1. Introduction: Personal finance
example problems including time value of money. Excel is a project-based
course containing multiple practical personal finance related
practice problems, which will contain a time value of money component to them, often needing calculations of present value and future
value calculations, which we will do using Excel. Down below, we have some Excel worksheets
that can be downloaded. Most of the Excel worksheets
will have at least two tabs. One will have the
answer key for it. So you can see how everything
is structured when it is all said and
done and completed. Another tab where we will be working the practice problem in a step-by-step fashion along with the instructional videos, the end result, the
final project will be the completed
Excel worksheets.
2. Rate of Increase: Personal finance practice
problem using Excel, calculating the
rate of increase. Prepare to get financially fit by practicing personal finance. We are in our Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down here
in the practice tab as opposed to the example
to have the example tab, in essence being an answer key, we have the information on the left-hand side
going to populate that into the blue area on
the right hand side, calculating our rate of return. Common kind of statistic that
we need to get in our mind. One which oftentimes people have trouble with thinking about percentages are kinda scared of ratios and percentages
sometimes, but they're really important for many different kinds
of measurement things, especially in finance, but with any kind of thing that you're trying to measure performance. Oftentimes with job performance, these types of calculations
being important as well, which we can see when we look at a particular and popular type
of job that being sports, where we break down to
basically statistics, which is basically job
performance for athletes. So what we have here,
we've got the purchase of a truck and we're going to say the cost at
Purchase was $18 thousand. And then we're going
to say that years have past five years have passed. The current price of the truck, or a similar truck
would be $22 thousand. Note what we're measuring here, we're not saying that we
purchased the truck and that particular truck
went up in value, that's not likely to happen. Most likely the truck
will decline in value due to depreciation. What we're saying here is that
similar trucks are going, the current price of a
similar truck is at the 22 thousand and that
would be one indication that we would think
one possibility or reason why that might be is because of the time value of money or inflation taking place. Meaning goods over time might be costing more because
the dollar itself is going down in value
when we're doing long time projections
about our budgeting, we need to take
into consideration the cost of the dollar. Typical trend, which will
be that the price of things we'll use it usually
be going up. In the US. They actually tried
to have the price go up by like
anywhere between 1, 3% is basically normal
rate of inflation. So you've got to take
that into consideration. If inflation gets
out of control, then it can go up by
significantly more than that. It could have a
significant impact on your budget and your purchasing
power in the future. It's really useful for us
to think about this kind of increase in terms of the
dollar amount change, but also in terms of
the percentage change. Because then we
can do things like in this scenario, we
can do things and say, well, if the car went
up by that much, Is that the same rate? That's a milk is going up or cheese or something like
that daily other products, are they going up
by similar rates? Can I assume an array greatly
increase, such as that? So let's take a look at this.
We're gonna say, alright, how would we calculate
the percentage increase? We're gonna take
the current price, the current price of the truck. I'm going to take
the later price, first tier, which
is the 22 thousand, assuming a similar truck
goes up to 22 thousand. Notice I'm just
using keyboard here, equals down, down,
down, left, left, left. And we're always taken
our data from the, from the information on the left-hand side
as much as possible so that if we wanted to change scenarios and run
different scenarios, we can do so by simply changing the data that will then populate our worksheet
to the right. Then we're going to say the
cost of truck in the past. And I'm gonna pick up
this information by picking it up on the cell B2. So I'm going to say equals
left, left, left, up. And there's the
1800s in cell B2. Enter. Let's go ahead and
underline that cell by going to the Home
tab font group. And underline, we can look at the dollar difference or
the change over time, which will be a
subtraction problem, which I'm going to put in
Excel by saying equals, use the up arrow, up, up to get to the
22 thousand minus. That brings me back to the cell. Then I'm going to use
the up arrow one time to get to that number and enter. So we have a difference
of 4 thousand. That 4 thousand is useful when you're comparing
things of a similar nature. But like I said, if you're
comparing this change or increase in price
to something else, like possibly are trying to drive some kind of
information from this to think about a change in your grocery list or
something like that, then you can't really do
it with the dollar change. And the similar kind
of thing will happen if you're measuring something
like work performance. So if you're trying to measure somebody's batting average, you got to take into
consideration that one person batted more
times than another person. It would not be fair if
you're talking about one person that got 20 at bats versus the other and
thick got ten and trying to see how many hits they
got or something like that. Or if you're a teacher
and you're trying to see how many people are
showing up to the course, it wouldn't be fair
if you're saying five people were absent from this course versus this course. But one course has 30 people in, the other course has 100 people in it or something like that. You can't, you gotta,
you gotta use these. Percentages in order to
make accurate comparisons. And these are things like I say, a lot of people
don't quite grasp. And when you're looking at
finance and even when you're looking at job performance
or something like that, people will often not know
how to apply statistics and, or purposely manipulate or
basically Lie with Statistics. And the way you lie
with statistics is not that the statistics
themselves are bad. It's just the same way you
lie with anything else. You basically give a half truth about the statistics and then you pack up a bunch of lies
on top of the half-truth. It's just that people are less good at picking up lies
related to statistics. When you do that verbally, you tell someone some
little fragment of a truth and then you pack
a bunch of lies on it. People are usually more sophisticated with words
and they're saying, Hey, look, you're totally lying. You said one true thing and you pack a bunch of lies
on top of it. Same. There's nothing wrong
with statistics. Statistics are good,
but truth needs to be. You've got to find
multiple angles to find the actual truth. If someone gives you
just one statistic for a complex thing and then
gives you a bunch of lives. That's not enough. Okay, So in any
case, we're going to compare that to the
original cost here. This is how you get the
percentage increase, which is gonna be equal to, I'm going to pick up
the same 18 thousand, the same 18 thousand. And so notice what
we compare it to. We compare it to
the original price. We don't compare it
to the second price. That's where the confusion
comes in oftentimes, and that's gonna
give us our rate of increase, rate of increase. I'm gonna go ahead and
put an underline under the 1800s by going
to the Home tab, font group and underline. And then we'll divide this out. We're going to take the 4
thousand divided by the 1800s. So this will equal, I'm going to hit
the up arrow twice, up, up to the 4 thousand, divided by the up arrow
once to the 1800s, E4 divided by E5 and
enter there, we have it. Now we got to make it a percent
so we can see the change. We're gonna go to the Home
tab to do that font group. And then you could
have the decimals. There's the decimal format. And then I'm going
to add it per cent. That moves the decimal
place two places over, adds the percent, then add a
couple of percentages here. So that's the percent
increase over that timeframe, which is five years here. Let's do a similar kind of
process and think about, well, what if we had a
year-by-year change? And we can think about
the percentage change on a year-by-year level. This can give us some idea of trends that are
happening over time. So this was a change that took place over a five-year period. Let's bring out these
numbers and imagine that these were the increases
from years 2345. And we'll do like a running
balance type of calculation. Now I'd like to get my
data as close to my, my calculations as possible. So I'm going to try to hide
some cells to do that. To do that, let's put
our cursor on column D. Left-click, drag on over to
column F, and then let go, right-click on that
selected area and then hide. So there we have it. And now I'm just
going to basically do a running balance kind of calculation will have the years, the amount that change, and the percent change. And note the table's already
set up for you here. But if you could start to
get a picture of the tables, knowing what you're going
to have in the columns and the rows is often a skill that is where it's a skill It's definitely
worth having and it takes practice to kinda see how you'd set
up a table here. So practice setting up a table. So we're going to have
year one, year one. And then I'm going to
say this is gonna be equal to year two. I'm just going to sit notice
I'm going to say equal, even though this
is not a number, but a words down here. So I'm going to say equal
and I can still pick up the words just like I
would with a number. And so I'm going to
say equals down, down, down, down, left,
left, left, and enter. And I could do that
all the way down, equals down, down, left, left, and then equals down,
down, down left, left, and then equals down, down, down, left, left. Also note, I could use the
autofill to do that as well. And anytime you want to
get used to basically just being able to see
when you can auto fill. So to show that I'm going to delete these ones. I just did. This one. If I double-click on that
is coming from here, if I copy this cell down, it will take the relative
cell as I go down, it'll go down each one cell. I should be able to simply auto fill this down, which
would be faster. So let's practice that. Putting our cursor
on the fill handle, dragging it on down
and there we have it, years one through five. So now we're going to pick
up the amount in year one. We have the 1800s
thousand year two, we got the numbers down here. I'm just going to
say equals down, down, down, down,
down, left, left, left equals down, down, down, down, left, left, left t equals down, down, down, down,
left, left, left. And equals down, down, down, down, left, left, left. Notice you can, you're
probably saying, Hey, why don't you
use the Auto Filter. I'm hoping you're saying that we serve so you could
use the autofill, gets weaker. Let's do that. Let's delete these ones and say, this one is coming
from right there. If I copy it down, I should be able to
use the autofill. Let's try it out. For
our cursor on it, put our cursor on
the fill handle, drag it down. There we go. Now this is the
same as copying and pasting would be the
same just so you know, I'll show you that
just real quick. If I copy this down, Control C or right-click and copy and pasting when I paste, I'm pasting the formulas. If I paste the first one, and that'll do the same thing in that instance as the autofill. Then we're going
to have to change. Now there's no change
in column one. The change in into
is simply going to be the second year
minus the first year. So I'm not looking at
a five-year change. I'm looking at a
year-by-year change, and I want to do this in
a running balance format. So this is gonna be equal to
left once minus left and up. So the 1850s minus 18 thousand, I'll do it again, equals
left ones minus left and up. Do it again equals left
ones minus left and up. One more time equals left
wants minus left and up. Now this one's a little
bit more complex, but you can use the
autofill with this one as well because everything's
within the table. So you would think that
if I copy it down, all the relative sales should copy down appropriately.
Let's check it out. I'm going to delete these. Put my cursor back on the 750, which is the 1850s
minus the 1800s. Put my cursor on the autofill handle right here
and left-click, drag it on down. And then I will typically
double-check it by double-clicking on one
of the cells and see, yes, it does indeed look like it's doing what we
expected it to. Then we'll take the
percent change. Now the percent change
is always the change, the difference that we
calculated from period to period divided by the
beginning period. So you're always divided
by the beginning period. That's where people kind of
get a little bit mixed up. That's why I'm
saying that loud and emphasizing that point because that's where people get
mixed up sometimes. So we're gonna say this equals
left once divided by left, left up the 1800s. And then this one, the
wallets percent of phi, that one we're gonna go to
the Home tab number group. You can add decimals
or you can make it a percent and add decimals. Let's do it here. This is going to be
equal to the change, which is going to be the 6,600 divided by the year two amount, because that's 600 is a
result of the 1850s minus the 1870s were looking
at the difference between year 32. So
there we have it. Let's go ahead and
let's use this time. I'm going to use the paintbrush in order to paint
the formatting. So I'm gonna go to the Home tab, clipboard Format
Painter, which will paint just the formatting
and then put that down here. So it has the same formatting
as the one above it. Anytime you're
looking at a cell, we don't know exactly
what the formatting is. That thing is useful. This is going to equal
the 550 divided by the 1850s format paintbrush it, clipboard Format Painter,
paintbrush one more time. This equals to 2100 divided
by the 199 format paintbrush, the one above it, Format
Painter paintbrush it. So there we have
it now, we could auto-fill that one down as well. So I'm going to delete these
and show that one more time. I'm going to delete these three. Try to simply copy this
one down because these are all even though it's a little complicated in the same table. Usually when you're dealing with something that
everything's in the same table and not in
the dataset to the left. You can copy it down and the relative cell references will do what you want them to. So we're gonna put our
cursor on the autofill, drag that on down. Then I'll typically
double-click one of the later ones to see if it's calculating the way we expect, and indeed it is. So now we've got our changes. Note that this dollar
change is useful. You can see the dollar
change and see how it's changing more one
year to the other. And you're like, well, four to five, there's
a big change there. What happened in four to five? And you can kinda
look into that there. But often that change, those big changes
stand out more, especially when
you're looking at those trends across
different kinds of things with the
percentage changes here. And I can say, well, that's
a big change in the percent. The price of milk grew up by 10.55 or something like that. You can start to ask those
questions and you can only do those kinds of comparisons
with the percentage change. Okay, so let's do the
same thing down here. But this time I want to, I want to see the change
compared to the base year, which is often a
common type of way. We would want to
see this meaning, I want to look at each year we have like we did
in year five and compete care each year to year one that we
started with the 1800s. Strive at this time, I want the years, the years are gonna be the same
as the one up top. You could copy these
and paste them. I would rather use formulas
whenever possible. So I'm going to use formulas. I'm going to say this equals
and I'm going to go up, up, up, up, up to that one. And then notice I
can auto-fill it down because these are all
relative cell reference. So I'm gonna put
my cursor back on this one and then
auto fill it down, putting my cursor
on the fill handle, dragging down like so. Then we have the amounts. The amounts are all going to
be the same here as well. So I'm just going to pick
up and do the same method. This equals the
one in the 1800s. And then Enter, I'm
going to auto-fill it down and I should have the
relative cells should, should populate
down here as well. Putting my cursor
on the autofill handle, left-click
dragging down. And there we have it again, bringing those cells down. Now this time, instead of
having a change column, I'm going to compare
everything to year one. Everything to the 800s thousand. So I'm gonna pick this one up and this time
I'm going to say equals the 1800s in my dataset. On the left-hand side. Note that since I'm picking something up from the dataset, if I copy it down, I might need to then make
it an absolute reference. In other words, if I want all
of these to be 18 thousand, which I do, I can't copy this one down because
it'll move the cell down. If I do so to five, I don't want it to do that. One way to fix that is I
can double-click on this. See the 100th thousand there, make this an absolute reference by putting my cursor in the b2, selecting F4 on
the keyboard and, or just putting a dollar sign
before the B and the two. That dollar sign
has nothing to do with dollars or a currency. It's just something
to tell Excel don't move the cell down
when I copy it down. And you only need a mixed references using
$1 sign instead of two. But $2 signs is conceptually
easier to think about. So absolute reference will work. Then I'll put my
cursor back on it, auto fill it on down. So now we've got the
1800s all the way down. Just so you know,
there's, there's another way sometimes
I will do that. Second method if I have
one number sometimes, and sometimes this is
useful, I'll delete this. I'll say equals
the one above it. And then I'll auto fill that down so I can auto
fill that down. And that means every sale
equals to one above it. So that if I changed
the first one, then it'll change all
the ones below it. But I think it's more
common to use this one. So I'll copy this back as the
absolute reference format. And then we'll have
the change here, which is just gonna be the
amount divided minus year one. This equals left, left the amount minus the
amount in year one. Obviously there's no change
from year one to year one. This equals the amount
minus the year one. This equals amount
minus year one. Then what I say I'm Malthus
is your three minus year one. This equals 0 or four
minus one equals 05 minus one. And so
there we have it. Could we auto fill
that one down? We could. So I'm going to delete these. Double-click here.
I can subtract that off by just saying
the autofill handle, grabbing the autofill
handle, dragging that down. I'll double-click it by
checking the last one. Looks good. Then we
can do our division. And it's always
gonna be the change divided by the starting point, which in this case is year one. That's our starting points. I'm gonna say this equals 0 divided by 18
thousand, which is 0. Even if we format it to home
tab number group Percent, define it, adding some
decimals. Let's do it here. This is going to be
equal to the change 750 divided by left, left the starting
point here, 118. That gives us,
let's go ahead and go to the Home tab number group. You could add decimals or
identify it and add decimals. Let's do it here. We're going to say this is
going to be equal to the 1350 divided by left,
left the 1800s. I'm going to use my
paintbrush this time. Home tab clipboard format, painter, paint, brushy it. And then we'll do that again. This equals left once 21900
divided by the 1800s. Let's paint brush
that 1750 paintbrush. Put that over here and
let's do it one more time. This equals the 4 thousand
divided by the 18 thousand. We could paintbrush that Home
tab paintbrush. Paintbrush. Could we auto fill that
one down? We could have. So let's do that one more time. Deleting these three,
selecting this one. This is the calculation. Putting my cursor on it, fill handle, left-click,
dragging it down. Then if I double-click
this last one, it does look like it's doing
what we'd expect it to. Notice that the bottom
line number here, 22 to 22, is basically what we got
in the first calculation. Meaning if I unhide
some cells up top, putting my cursor on
column B, left-click, dragging over to
column G, Let go, right-click on the selected area and unhide to
unhide these cells. We have the 2222. That's gonna be the change that we have here
on this last one. But now we're comparing each item to basically
the base year, which is another way
we can often see this kind of trend
type of analysis. And once again, the
percentage is often being useful when we're looking at
that kind of trend analysis. So like I said, these
don't be afraid of the statistics that makes
sure that you wanna be kinda comfortable with these
kind of basic statistics, these division kind of problems. They are fraction
type of problems and they come up all the time, not just in personal finance, just in your job reviews. If you're trying to trying
to judge someone else in their performance in some
way and you're not using statistics and you're comparing two people about something, you're probably not doing
it fairly. You got it. You have to use this statistics. And if someone's judging
you based on statistics, in some way judging
your performance, it'd be nice if you understood
what's, what's happening. So you can kind of determine whether or not
you're dealing with someone who's being fair
in their assessment, or possibly if they're
either not interpreting statistics properly or even intentionally misinterpreting
the statistics, which unfortunately is
obviously quite common as well.
3. Inflation & Estimated Increase in Personal Expenses: Personal finance
practice problem using Excel inflation and estimated increase in
personal expenses. Prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, I'd like to follow along
note that we're down here in the practice to have as
opposed to the example tab. The example tab, in essence
being an answer key, we have the information on the left-hand side going to populate that into the blue area
on the right-hand side, information saying that
we're going to estimate the personal expenses per year, costing us then per year
for personal expenses, 66 thousand, we're
going to assume that there's a yearly
inflation rate of 5%. And then ask ourselves
how much we're going to need in two years in order to cover the same kind of personal expenses
given the inflation. So we're going to use our same kinda future value calculation to estimate how
much we will need. But we're going to use it a little bit differently
because most of the time when people think about a future value calculation, as we saw in the past, we use it to basically estimate how much growth there might be in something
like an investment, like a savings account, like a stocks or bonds or our home going up in value
or something like that. Now we're applying
it to something which is going to
be the inflation. How much is the inflation
is going to be impacting? How much we'll have to
typically spend for the same amount of
goods in two years. So quick recap on inflation. That's gonna be the
purchasing power of the dollar going down. And notice there's gonna
be times in the economy. And I'm usually speaking from the standpoint of
the US economy, but the same will be true around the world with regards to inflation and the currency and purchasing power of the
currency and the US, it can be fairly stable when
compared to other countries. Just note that that doesn't mean that you won't have
to experience in your lifetime time
periods where inflation basically goes up and time periods when
inflation goes down. So when we're doing
long-term planning, we want to make sure
that we're taking into consideration the
likelihood that in our lifetime we're
going to have to experience increased and
decreased inflations. And we might have
extended periods of higher inflation and extended
periods of lower inflation. Both those two extremes make us feel like that's
always gonna be the way it is, like that's the new norm. And as soon as we
feel like that's the new norm, something
often changes. To change the new
norm does something. So note, the Federal
Reserve in the US usually shoots for inflation
of about one to 3%. Meaning they actually want the purchasing power
of the dollar to go down by some
systematic component to make sure that
there's enough money, currency in the market and
the economy in order to meet the needs of kind of like the lifeblood of the
economy is cash. So they want to make
sure that they have the right amount of cash there, but they try not to let
it go too much over that one to 3% and they
look at that closely. But again, the fact that
we try to do that doesn't mean it couldn't get out of control at some point in time. So we want to account for that. So we're going to
assume 5% which is above the norm and the US, which would be 123. But like I said, it's nowhere
really out-of-control. 5% is still within the realm. If something got out of control, you can have very
extreme interest rates was hopefully it doesn't happen. But that's the idea here. So the idea then being if I'm
spending my money today on a basket of goods to things
like food and whatnot then, and it cost me 66 thousand. And the money that
I have is going down by 5% in terms
of purchasing power, then how much will it cost me to live the same in terms
of my consumption, to spend the same
amount of money. So we're gonna do our
future value type of calculation in a similar
way as we did in the past. To do that, let's first take a look at our running
balance calculation, which is a useful thing to
give us more context than simply a future value
formula or function. So I'm gonna do are
running balanced table. I'm going to start
at period 012. We're going to use
our autofill to auto-fill the rest
of the way down. So I'm going to select
these three cells, going to put my cursor on the fill handle and
drag it on down to it continues on the
series to four periods down. Going to center this by going
to the Home tab up top, go into the alignment, and then we're
going to center it. So there we have it.
I'm going to start with the investment out here in F2. We're going to continue
on with our practice. I'm not typing in the 66 thousand at period
0, but saying equals, I'm hitting the left arrow on the keyboard,
left, left, left, and up to get to
cell B1 and enter. So we're gonna do a same kind of calculation as we
saw if I was to think about this as an
investment that was going up. But now I'm thinking about it as the expenses that I need to cover and how much I'm going to need in order to
cover those expenses. If we assume the purchasing
power goes down. So we're going to say, Alright, That means that
I'm going to take that 66 thousand times
the 5% increase. So let's do that this way. This equals left up
times, I'm sorry, that was right and up
and then times left, left, left to the five per cent. So F2 times B3 and Enter. Now I'm going to do
an absolute reference later so that we
can copy it down. But before we do it,
let's just calculate it straight away a few times. So that means that we had
66 thousand before and now it's going to cost us
another 3,300 after year one. If there's 5%,
basically inflation, that means it's going to take $69,300 to purchase
the same stuff that we purchased last time, like food and gas and whatnot
or personal expenses, cost us to 66
thousand last time. Now remember, that
doesn't mean that everything's going to
go up exactly the same. Sometimes food will go up more
and sometimes gas will go up and they could
go up and down. But we're trying to
get a broad idea of how much we're going to need in our total basic
expenses categorization by broadly categorizing
what inflation will be. Also note when you
talk to inflation or listen to people talking
about inflation, they will often use
terms like it's gonna be a short-term inflation are transitory or
long-term inflation. And in order to basically lock into what they're really
concerned about for the economy. Long-term inflation
problems, they often eliminate things that are the things you actually
spend money on. Food, electricity, gas, the things that are actually
important to most people. Oftentimes will be
taken out when you consider the impact of the
entire economy because they're trying to find out what the long-term inflation
indicators will be in trying to determine if inflation
will be short-term. But whether it's
short-term or not, if your food costs
go up your gas, then that's gonna be a problem. And you want to
calculate that and take that into
consideration so that the numbers that you'll
hear then from the Fed or from news anchors and
whatnot will be a kind of, you can't really go off it
completely all the time because they're looking in
terms of the broader economy. Oftentimes in any case, we're
then gonna do this again. This equals to 693 times, and then we'll pick
up the 5% again. So now it's gonna go up by
another 3 thousand for 65. And then I'm going
to say, alright, that means that we have
last time equals up to the 69300 plus left wants to
the 3 thousand for 65. That means that now it's
going to cost us 72,765. And notice this starts to
grow up quite quickly at even a modest rate of
inflation of the 5%, it's going to cost
us 72 thousand, 765, whereas in period 02 years ago, it only cost us the 66 thousand. Let's do it again. This is
going to be equal to the 72765 times the 5% left, left, left up, up. Now it's going to
be another 3,638. This is gonna be equal to
the 727625 plus the 3638. And now it's going
to cost us 76403 to get the same amount of stuff, which way back in period
0 cost us 266 thousand. Let's go ahead and do this with a running balance calculations. So I'm actually going
to delete these items, do it one more time, this time the easy way so we
can calculate it quickly. I'm going to delete these items. This first one, again
by saying equals right up to the 66
thousand times left, left, the five per cent. Now that 5% is
outside of the table. Anything that's
outside the table when I think about copying it down is something
I would think that I might need an
absolute reference for. I'm not gonna do it yet. I'll do that in a second just to prove
that I will need it. And then we're going to say
this equals the one above it plus the one to
the left of it. And so there's the 693, which is the 66
thousand plus 3,300. Let's go ahead and copy this
down and we'll see that we have a problem when we do so. So I'm gonna select these two, put our cursor on
the fill handle, left-click on it,
drag it on down. We have a problem because
that shouldn't be 0, that shouldn't be 0.
What should it be? Well, it should be taken that
number that looks right, but this 5% is wrong because it moved it down and it
should be 5% and it's not. So we need to fix it with
an absolute reference. So I'm going to delete
these second two here, selecting them, deleting them. I'm going to fix this
one before dragging it down again,
double-clicking on it. There's the 5% in cell B3. Putting my cursor and B3, we want to absolute ties it, which isn't really a word,
but I think it works. I'm going to put F4 on the keyboard to make it
an absolute reference, which is the proper phrase, dollar sign before the B
dollar sign before the three, you only need a mixed reference, but an absolute references kinda easier to understand because it basically means or telling Excel not to move
that cell down. Dollar signs having nothing
to do with dollars, simply code for Excel, telling it not to
move this cell down. Enter. Then I'll typically select
these two and move it down one cell just to double-check that it's
doing what I wanted to do. If I'm if I'm not sure that it will auto fill that
down, does look right. Let's double-click on it. That looks like it's doing
what we want. It looks good. Let's drag it on
down to your four then selecting these two cells, putting our cursor
on the fill handle, dragging it on down. Year for year four, we're up to 80 thousand to
23 to buy the same stuff. My food, the food I need
that I would only cost me 66 thousand like four years or five years ago or
something like that. Things are getting
out of control. The world's going to **** in
a hand basket these days. I remember when I used
to be able to buy a hamburger, happy meal anyway. Okay, so now I'm going
to hide some cells. Let's do this with just the
future value calculation instead of a running balance. To get over there, we're
going to hide some cells. So I'm going to put my
cursor on column D. We're going to hide the
columns, left-click on it. And we're going to drag
on over to column G. Let go. I'm going to right-click
on those selected areas and hide them
practicing are working within Excel so that we have our dataset right next to
where we're gonna be working. Once again, let's do our future value
this time I'm going to do it just for two years out. So we're gonna say two
years out, how much wood, how much would we need if we
add 66 thousand to pay for the stuff that we want
this time and we want to buy the same food
and gas and whatnot. And there's a 5% inflation. How much would we
need two years out? Well, we could do is simply
the future value calculation instead of a running
balance calculation. Although the running
balance calculation does give us that more
detailed information, I'm going to say this equals the future value FV shift nine. And then I'm going
to use my keyboard. So I'm going to go
left, left, left. We're looking for the
rate, just like it says right here in our
little data thing. So we pick up the rate that 5%, I'm not going to type in 5%. I want to pick that up
from the data because that's the proper way to
set up an Excel worksheet. Because then we can check and we can say, well,
what if it was 6%? What if it was 3%? And
we can see what's going to happen and run different
scenarios with it. Then I'm going to say
comma, number of periods. The number of periods
we're going to say is two, which I'm going to pick
up in our dataset down here as well instead
of just typing too. So I'm going to say
down, down, down, down on the arrow,
left, left, left. There's two comma. Now it's not a payment because
this is not an annuity. We're saying it's the same
662 and that's going up. We're not talking about
multiple payments. Therefore, I'm just gonna put two comments to move on
over to the next argument, which is the present value. Present value is
the starting point, which is the 66 thousand. I'm not going to hard
code it in there, but rather go down
left, left, left, and up to get to
that 66 thousand, we could close it up
with the brackets here, but we don't need to, because
Excel will do that for us. So I'm just going to say Enter. There, we have it. Although it's negative. If we don't want it to be negative, we can flip the sign by
double-clicking on it. You can see the brackets are now closed automatically by Excel, you could put a negative
before the present value, which is probably the
most proper way to do it. But I like to put
the negative right before future value on these present value,
future value ones, because it's the easiest
thing to see, in essence, multiplying the
whole thing times negative one, flipping the sign. So that means two years out, we can expect to pay 72765
to eat the same amount of stuff and get the same gas and
driving round that we did. Now, We gotta take, obviously, that's important,
got to take that into consideration
when planning here. So we got the, let's do
this with a table format. We could do that with
a table down here. So we could do the same
thing with a table. So let's say we have
the amount in year one. And let's imagine that
was the 66 thousand. And let's imagine they took away our Excel and they took away our calculator because
it's some kind of test question or
they're just mean. And they took away all the stuff that to make the
calculation easy. But they gave us this
table down here, so we don't have to
do it with math, so they're not totally cruel, but they made it a
little bit harder. So we're gonna go down
here and say, all right, it's gonna be the rate 5% and it's gonna be two
periods, two years out. Notice this rate
and the periods on this table and meaning also note we have to
have the proper table, which is the future value table, as opposed to the
present value table. It's not an annuity table, which would be a
series of payments, but present value of one or
future value of one table. The rates do happen to line up two years here because that's
what we're talking about, years and the periods
then will be years. But note you can
use the same table if you're talking about
any other period, as long as the rate
aligns up to it. In other words, if you
were talking about half years for like bonds
or something like that, then you'd have to make sure that the rates that
you're looking up here would represent
half-year rates, not the typical yearly rate, and then the table
who will still work. Okay, so we're taking the 5% 2 years out,
that on the table. The table gives us 1.1025. Notice that this is rounded
to four digits out, so it's not quite as exact
from the table because there could be multiple decimals
for the actual number. So we're going to be
rounding four digits out. So that's gonna be 1.1025. And I'm going to add
decimals here by going to the Home
tab number group, adding four decimals,
four decimals, decimal wise in it as
I like to call it. So we're going to say
the table amount, not an actual term
desk normalizing. But I think it just sounds good. Home tab, font group underline. And then we're going to say
then that's going to be the amount for year
two or two years out, which is going to be equal to up to the 66 thousand times up one, the 1.10 to five that gives
us our 72765. Once again. Now we're gonna do
it one more time. Let's do it with a formula, same calculation, but with
a mathematical formula, we're thinking that
our instructor now we're out of school, most likely they're making
it even there even crueler. That they took away
our calculator, they took away excel, and they didn't
give us any tables. I still make us do it with a formula like a
paper and pencil, like we're cavemen,
like it's any case. So we're going to hide the
cells to get over to column K, Putting our cursor on H, dragging over two j here so that we can hide
these cells and be working right next to the
data we're working on, right-click and hide. So now we're going to be
putting this formula, future value equals the
present value times one plus r to the n. So
ours being the rate, N being the number of periods. I'm going to put this into an Excel format to
table the same thing, algebraic item into a table. You could type it
out algebraically, of course, and just
enter the data this way. It would be, the
future value would be the unknown, would be, future value is going to be
equal to the present value is 66 thousand times times. Where's the times three times? And then one plus the rate, which is going to be 0.05 or
5% carrot to the six carat. Two. We're doing two periods out. So you could do that and
then solve it that way. I think it's useful to
put it into a table. And a lot of these
calculations you might actually start to
visualize in a table. So even in a test
question scenario, you might start to visualize
it in a table format. So if that's helpful,
That's helpful. Good to do in practice to work on putting things into tables, because it can be
useful depending on what you're doing that way. So I'm going to take
this information. I got two major components here that I want to
multiply together. So when I imagine putting
that into a table, kind of like we would do for a tax worksheet or
something like that, or some type of Excel worksheet. I want these two on
the outer column. Any other details such as
the one plus r to the n, I'm going to bring insight
to a sub calculation. So we're going to
have then the present value and the outer column. Present value in
the outer column, I'm going to pull the data
over from our sheets, so equals the 66 thousand. And then I'm going to
pick up a subcategory, which is going to
be this other side because it has other
stuff involved in it. I'm going to make a
subcategory of the one plus r to the n periods colon, indicating I'm going to pull
that into the inner column. And then the end result will
be in the outer column, which we can then
multiply it together. This is a similar format
that you'll see in financial statements
and whatnot, useful to kind of get an
idea of how you might structure these things
and how you might read these things
once structured. So we're going to say one. And then the rate, the
rate is going to be, rate is going to be the 5%. I'm going to take that from the table over here,
not type it in. So equals left, left, left, up, up, and enter. Going to make that a
percent in that cell by going to the Home
tab numbers group, you could add decimals. There's the 0.05, or
you could make it a percent by moving the
decimal two places over, adding the percent. And I do that by clicking
this little percent thing. And then font group
and underline. And that's gonna give us
then the one plus the rate. So we can sum that up. The one represents
100% of course, and the five per
cent equals the SUM. You gotta know that some
function shift nine. I'm going to do this
just with the keyboard. Up arrow once, holding down, Shift up arrow again. And then I can close
it up if I want to. You don't have to, because
Excel will do it for you. And there it is. Let's make that than a percent. Go into the home tab number
group, add some decimals. It could be 1.05 or you can
reflect it as a percent, which would be 105 per cent. Then we're going to take that
to the number of periods, which is going to be the number, I'm going to say to n periods. And that's gonna be two periods that we're taking it
to two years out. We're going to assume,
I'm going to take that from our Data tab over here. So equals the two going
to underline that by going to the Home tab
number group, underline it. And that's gonna be our total
here, which is going to be, I'll type that out again, it's gonna be one plus the rate. And then we take that to
shift 67 and periods. And then I put in periods here and that's going to be in the
outer column now. So this is the
final calculation, so I'm going to bring that
into the outer column. So this whole half
is now outside here. This equals left up, up the 10, 5%. Shift six for the carrot, which is to the power of
two or squared and enter. So there we have it. Now we're going to make
that add some decimals to it by going to the Home
tab numbers group. Let's add some decimals. It's going to add
a bunch of them. It could go on for
quite some time. We're at the 1.125 and that'll give us the end
result of the future value, which we're looking for here. This times this outer column. Now let's underline this first, just to add some more suspense. Font group underline it. And then we're gonna, we're
gonna, we're gonna multiply, I'm sorry, multiply the
outer column equals up, up, up to the 66 thousand
times this number we got to there and enter there
it is again, 72765. Let's just do some formatting just to shore this thing up. I would like this colon
means that we brought it to the inside for
subcategory calculation. Let's go ahead and
indent it just so we can redundantly indicate
that same thing, that this is a subcategory
of that item up top. By going to the Home
tab Alignment indent. Then I'll indent this one again, indicating that
now we're bringing that to the outer column, Home tab Alignment indent. Again, there we have it. Let's go ahead and unhide
some cells between b and k here so we can see all the wonderful work
that we have done. Let's go to our b,
left-click on it, drag on over to k, and then let go, right-click the selected area and unhide. And so there we have it.
So we add the 72765 here. We've got the 727065 there, we've got the 7765 here, and the 727065 here, representing once again,
what we really need to take into consideration
when we're doing budgeting in the future. The fact that the value of the dollars that
we're going to be spending will typically
be going down if you're in the US
somewhere between 13, possibly one in five. And if we are in a place of higher inflation as
the US is subject to, from time to time. Even though you might have
long periods without that, then it could be
higher than that. And we would just
want to take that into consideration, of course, especially when we're taking long-term planning into
consideration for our budgeting.
4. Home Cost Estimated Increase: Personal finance practice
problem using Excel, home cost, estimated increase,
prepare to get financially fit by
practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example. The example tab, in essence
being an answer key, we have the information on the left-hand side
going to populate that into the blue area
on the right-hand side. Our question being that
we're thinking about a home price starting
at this time period, at the 200 thousand, we're going to have an expected annual increase on the price 2%. And we're questioning
how much will be needed to buy an eight years. So this is a question
that some people might have in terms
of purchasing a home, might be planning
out to purchase a home at some point
in the future. In order to do that, There's a couple of steps that we would need to keep in mind. One, What's gonna
be the price of the area that we're looking
to purchase in at this 0.2, what do we expect
the price to be in the future as values go up, we would expect generally
all else equal over time. Once you have the target, then that should be aiming for. Then you can think about
how much you would need to save in
order to get there, how much you would have
to invest each year. An investment type of
calculation taking into consideration loans and whatnot as you do so in
downpayment and so on. So here we're just
thinking about the value of the home itself. And it's similar to
an inflation type of calculation because
all else equal, we would expect things
to typically go up in value due to the decrease in
the valuation of the dollar. However, note that the homes, of course, are gonna be
specific to a particular area. So this is another area
where you can kinda see the increase or decrease in the homes in a particular area. Measure that possibly to increases in other
types of things. To try to determine how much of the increase might
be due to, say, inflation and how much of it is going to be due
to other factors. But in any case, with regards to the home, a small increase in the value could have a significant impact
given the fact that the purchasing value
of the home is substantial generally for
individual purchasers, there's therefore a
small increase is something that
you'd want to make sure you're planning in? If we were to if we were
to think about purchasing a home and plan for it at
some point in the future. So we're going to say it, Let's gonna be
similar to our type of calculation for inflation. Note that when we look at our
future value calculations, which is what we're going to
use most of the time when you were to ask someone what a future value
calculation will be, they'll usually have an
investment scenario, meaning you're going to say
I've put some money down, how much will I have
at some point in the future given the
increase in the investments? We've been looking here
at how we can apply it to basically
purchasing in the future, meaning prices go up and inflation type of
scenario, or in this case, the home we're
expecting to go up at some rate in the future and
in our planning component. So let's do first are running balanced type of calculation. We're going to
have the number of years on the right-hand side. We'll just list out the eight
years and see how much we expect it to increase on
a year-by-year basis. And this is a really
good calculation because they can kind of give us an idea of where
we are at any point. So if we get, if we get above in our plans
and we're like, Now I can purchase
the home sooner. How much advantageous
would it be for me to do so if I'm estimating
a 2% increase. So I'm gonna say 12. We will put our cursor
on the fill handle, drag that on down. That'll take us down to eight. Let's center that by going to the Home tab
Alignment and center. And then I'm going
to put the price on the right-hand side. We're going to do that
not by typing it in, but rather with a formula
saying equals left, left, left, left, and up the
200 thousand and enter. Now we're gonna do
our calculation for the increase that
we're estimating. A 2% increase will do
that with a function once again equals right
arrow up arrow. And then we're going
to say times left, left, left to the 2%. So F2 times B3 and Enter. So we've got the 400
thousand increased plus the 200 thousand is
what we want here. So this is gonna be
equal up once to the 200 thousand plus left
ones to the 404 thousand, and that gives us 204
thousand after one year. That's what we expect to
be paying or would need to pay at that 2% increase.
Let's do it again. This time. This is gonna be
equal to write up the two O 4 thousand times left, left, left up, and enter 4,080. Then we're going to say this
equals the 204 thousand plus the 4,080
given us the 20880. Let's do it two more times
and then we'll think about how to do it the easy
way, autofill way. So we're going to do it again. This equals right
and up times left, left, left, up, up to
the 2% and enter 4,162. And then we're going to say
this equals the one above the 20880 plus the one to
the left of 4,162. And enter, that gives us
the 212 to 421 more time. Let's do it. This is going
to be equal to right and up to 12 to 42 times left, left, left, up, up, up 2%, enter 4 thousand to 45. And then this is going to be
equal to the one above it, 2012 to 42 plus the
one to the left, 4 thousand to 45 and enter
given us 2006 to 216,486. Price after four years. Let's do it again, this
time using the autofill, doing it the easy way. So we're going to
select these items. I'm just going to
delete the entire thing and do it one more time. Keeping in mind the
autofill option, this is going to be equal
to write up times the 2%. Now that 2% is outside
of my table here. So I'm going to think
that I need to make that an absolute reference
or a mixed reference. I won't do it yet.
I'm going to then go, okay, I'm going to keep
that in my mind there. And this is going to
be equal to one above it plus the one to the left. And then I'll copy it down
to verify whether or not I'm right or wrong about that
absolute referenced cell. It's auto fill this
down just one set. Double-click on this and I
can say, Yeah, that one, move down, it shouldn't have this one's doing what we want. This one's doing what we want. So let's go back up. Let's delete these two and double-click on
this 4 thousand. I'm gonna make that
one. And B3 absolute, absolute ties in it, which isn't a word, but
I like the way it rings, like the way it
sounds by hitting F4 dollar sign before the B
dollar sign before the three, you only need $1 sign
for a mixed reference, but absolute will work. Dollar signs have nothing to do. You'll recall with
actual dollars it's just a code in Excel telling
Excel do not move that down. Enter. Let's copy this
all the way down. Now I'm gonna do, I'm
gonna be confident this time and copy
it all the way down. Autofill handle, dragging
it all the way down. I will then typically
double-click on the last one
or something like that to see if it does indeed do what we think it should do. And it does indeed do the
thing that we did it for. So there we have it. So that means at the end of eight years we're
looking 234332, significant increase in the
price given the fact that we're only looking at a
2% increase in the value. Remember, inflation
could be anywhere from 0 to 3% if they're, if they're not out of
control and the Fed too. So That's not certainly
not out of a, out of the range of the increase on a home price possibly. So let's go ahead and
hide these selfless. Do it a couple of
different ways. Let's do it with the
formula in Excel. Let's do with tables. Let's do it with a formula. So I'm going to put my cursor on D. I'm going to select over to, I think as g over here, so that we can hide these cells. So we can have our data right next to where
we are gonna do the data input,
right-click and hide. And let's do that here.
So now we're gonna do the future value calculation. This is the easy
way of doing it, but you don't get all
the detail this way. So we're going to
type in future value and we can double-click
on this one here or hit Shift Nine, which is the cooler
way to do it, or the nerdy or way to do it, which is cooler in the
sense that faster. So in any case, we're
then going to go left and then down. We want the 2%. So there's
the 2% on the rate. And then comma,
number of periods, we're gonna go left,
left, left, down, down, down, down eight periods. So there we have that. And then comma, and then
we have the payment. There is no payment because
this is not an annuity. So we're just going
to have two commas bringing us over to
the present value, which we're going
to pick up, left, left, left, and there it is. We could close it up
with the brackets. I'm just gonna leave
it as is the Excel. We'll close it up for us. There we have it. I think that's the same
number, isn't it? Pretty sure. Then it's negative. So I want to flip the
sign to positive numbers. I'm going to double-click on it. You could put a negative in
front of the present value. Probably the more
proper way to do it. But I liked doing it in front of the f over here is I put my
cursor in front of the f, put a negative in
front of it and enter flipping the sign. Now we can do it with the table. So the table is once again
would be used of course, in a situation where some cruel, some cruel school or something
took your calculator and your Excel and
made you give them, gave you these tables. Like you're in a cave, like you're a caveman. And you had to look at these tables to figure
out what you wanna do. If they do that, then
we can go, okay, we're gonna take the 200 thousand and then
we're going to look at the 2% and the eight
years, 2%, 8 years. So we're going to
percent and eight years. So we're at the
1.17171.17171.1717. And let's add some decimals
by going to the Home tab up top Number group,
adding some decimals. There we have it. Notice it's rounded
to four digits. So if there's anything
more than four digits, we could have a rounding
difference there. And we're going to then say
this is from the table, this is the table amount. So nothing too unusual with the table this
way, by the way, we're using the table
in the normal way, get into the end result of the Future Value font
group underlying. And this is going to be our
amount or future value. Let's call it future value, which is going to be equal to up to 200 thousand
times the 1.1717. And so notice it's
slightly different than we got up top with the 342. The difference is. Is $8. So notice as you got
bigger dollar amounts, that difference could be larger and that could be
due to rounding. And remember, if you've got a maniacal test question person that's trying to make
you use the tables. They can use that difference of $8 to force you to
use the tables. Because if your answer is this, then they're going
to know that she didn't use tables because
if you did the tables, you would have got that. Now let's do it with
the formulas here. So I'm going to hide
some cells again, we'll do with the formula
by putting our cursor on H. I'm going to drag on over
to j and then let go, right-click on the selected
area and hide again. This time looking at
our formula tabs. So here's our formula. Future value equals the present value times one plus r to the n. Straightforward
calculation this time because we're solving
for the future value, we're going to put this
in a table format, meaning I want these
two components to be on the outer
side of the table and this component right here
to be in the inside. In a similar way as we
might see, you know, like a tax return or
financial statement format. So I'm going to put them
in the present values, our starting point
present value. And that's going to
be on the outside. This is going to be equal
to the 200 thousand. And then we're going
to have on the inside, we're going to do
this calculation of the one plus r to the n, which I'm gonna do an a sub
calculation indicated by the colon here,
starting with one. The rate is then
going to be rate. And the rate is going
to be equal to the 2%, going to pull that from
the table equals left, left, left, up, up to 2%. Gotta make that a percent so it doesn't look like a 0 there. Home tab numbers. We could add
decimals, by the way, to 0.02 or percent of it, which isn't a word
but I like it. Percent of fight, it's
been identified in Excel. And then we go to the Home
tab font group and underline. And then we got this is gonna
be the one plus the rate, which we could do
with the trustee. Some function equals the SUM. Got to know this function
should be automatic. Shift nine, if it is not, work on it, work on it. Holding Shift Down, Up Arrow, doing it completely with the keyboard as
nerdy as possible. And then we're gonna go
back on over here and make it a percent Home
tab number group. You could add decimals
at the 1.02 or you could then hit the
Percent button for the 102%. Then we're gonna go to
the number of periods. So it's gonna go to n periods. And the number of periods
is going to be eight. So I'm going to say equals. And we'll pull this over
from the eighth over here, underline it by going
to the Home tab, font group and underline. And then that's gonna be our end result for
this component. This is gonna be one plus rate, shift or shift six
carrot and periods. And we'll put that on the
outside now because now we've completed this
subsection category. So this is going to be
equal to left, Up, Up, shift six carrot left, once, up, once the, and enter. Let's make that a decimal. So we're going to add
decimals, Home tab numbers. And then usually if I'm adding a whole bunch of
decimals just to see how much I call it
desk normalizing it. It's been destined them allies. Which again isn't a word
you probably want to type down or anything might
not be in the spell check, but I like it. And then we're going to say
that this is going to be then the end result. Let's get rid of this year one. That's not necessary,
that's not necessary. Then we can multiply this out. So we've got the two
components here. So let's multiply this out.
This equals up, up, up, up, up 200 thousand times
the 1.11.1716594. And that keeps on going on
forever in Excel by the way, but we're rounding it, getting us to that to 34332. Let's do some indentation
here just to make this nice. So we've got this
colon, Let's indent these three to indicate
that this is gonna be a subcategory that
was brought into the inside by going to the
Home tab Alignment indent. Let's indent this one
again, Home tab Alignment, indent this kind of indenting in this kind of stuff because
probably seems tedious. It does to me, still kinda completely dead to me when I was
learning this stuff. Like this is not I
just get the answer. I don't, I just get the answer, but you gotta make it nice. Presentation is half the
battle because half the people you present
stuff to in real life, they have no idea
what you're talking about and you just go out
and make it look nice. If you make it look nice, then people are normally happy. Then we're going to
say, there we have it. And then, so now notice that this amount here should
match what's in the table. So if you go to the
table down here, at the eight years, we had the 1.171. That's how they get to
that amount on the table. And notice this one's
rounded to four digits. That's why you get with
a different number because this is
the actual number which isn't rounded
and the table has to round to some number of digits. So let's go ahead and unhide. Now we're gonna
put our cursor on B and drag on over to k. So the BK right-click on the
selected area and unhide. So there we have it. We got to this to 34332 with our running
balance calculation, to 34332 with a future value, we got to the 234340 because it's an estimate
from the tables. And then we got to
the 234332 with the calculation of the
formula for future value.
5. Savings Account Compounding Interest Future Value: Personal finance
practice problem using Excel savings account,
compounding interests, using future value,
prepare to get financially fit by
practicing personal finance. And we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence
being an answer key, we have the information
on the left-hand side gonna populate that
into the blue area. On the right-hand side, we're looking at future
value calculations. Probably one of the
most common examples of a future value calculation that being related to
a savings account. Thinking about what
the interest or what the amount will
be in the account and the future considering an interest rate that
will be applicable. We can have a similar type of calculation with any
type of investment, if it was like stocks or bonds or any other kind
of investment that we're assuming that will
be going up in value like land or a home. Although of course it would not be interested in those cases, but we can still assume an
increase in value over time. We did similar problems
to this in the past, but we ask the
question as to how long it would take for
something to double, which is slightly different
than just thinking about where you will be at some
point in the future. If you have an
investment and assume interest rate or annual increase that will compound annually, as we will do this time. We're going to say the
savings account has 5 thousand in interest
rates are at 4%. Now note 4% could be
reasonable depending on the time period in which you have your money in
a savings account. If you're in a time period
as we currently are, where the interest rates have
been historically low for quite some time than 4% might seem high if you put something
into a savings account. But if interest rates
were to increase, then you might see at 4% whatnot in say, a savings account. And remember that
these rates can be applicable to other types
of investments as well. In other words, the method being used could be similar
to if you have stocks, although it would not be
interested in that case, but you could still assume an increase in the
value of the holdings. You can do the same for bonds
and so on and so forth. So we're gonna say then, how much would you
have in years eight? So if you had the money
in the savings account, you held it in the savings
account, you're getting 4%, which you're
compounding annually in our practice problem, how much would you
have in eight years? Now, most of the time when you
have a question like this, people will pull up the
financial calculator or Excel, get right to that bottom
line, answer for it. And that's a great tool to have. It's useful to then look
at the actual compound. And so we're going
to start off with a running balance calculation. Highly recommend getting used to the running balance
calculation because it'll show you what's
actually happening with regards to the compounding
of the interest. So I'm going to
start off with 01. Then we're gonna do
our autofill function to copy that on down, we're going to select
those two cells, put our cursor on
the fill handle, left-click and
drag that on down. So that's gonna give
us eight periods. Let's center that. But I go into the home tab, Alignment Group and center, then we're going to be on the
investment side of things. It's gonna be 5 thousand. At our starting point. We're not going to simply
type in 5 thousand, but rather take that
information from the data. So I'm going to say
equals left, left, left, left, and up, there's the 5 thousand. Then we'll do our
calculation at the 4%, we have a 4% increase. So 5 thousand times 4% we're going to assume
is the interests, the interests that we're
assuming we're going to keep into the account
and accumulate upwards in the future then applying a growth on the
interest rate per compounding. So this is gonna
be equal to them, the 5 thousand, right once up, once times left, left, left that 4% and Enter. We're going to copy
this down later and we will need an absolute
reference to do so, but we won't do that yet. We're going to think
about that in the future. Then we have the 5
thousand plus the 200, which we're gonna do this way, equals one plus left one. There's the 5,200. Let's do this a few more
times now we have 5,200 instead of the original 5 thousand that we're gonna be multiplying times
the rate of 4%. So this is gonna be
equal to right once up, once times left, left, left, up, and enter. So now we've got
the 208 interests increasing due to
the compounding. And this is going
to be equal to one, the 5,200 plus left once
the 208 given us 500408, Let's do it two more times
and then we'll go back and copy it on down using
the autofill function. So we're going to say this is
equal to the right once up, once the 45408, times left, left, left, up, up the 4%
and enter there's the 216. Then we're going to add this up. This will be equal
to up once the 500408 plus left once the 216, that gives us the 5,624. Let's do it one more time. This is going to be
equal to write one's up, one's times left, left, left, up, up, up 4%, the 225. This is gonna be
equal to up once to 5,624 plus left wants
to two to five, that gives us the 5,849. Now I'm going to go back and delete what we've done thus far. Do it again, keeping in
mind what we need to do in order to copy it on
down with the autofill. Let's delete this
thing and do it again. And this time it's
gonna be equal to write up times the 4%. Anything I'm grabbing on
this right-hand side, when I'm keeping
in mind that I'm going to auto-fill it down. I'm going to start
thinking I need an absolute reference
because I don't want that 4% to go down. It's outside the table. I probably need to do that,
but I won't do it yet. We'll do it in a second here. And this is gonna be equal
to up once plus left once. Now let's autofill it down
one time, copy it down. This would be the
same as copying it. In this case, autofill handle, drag it down, and then
I double-click here. This number doesn't look right. I said, Yeah, I moved it, move that down. I
shouldn't have done that. I don't want it to do that. I don't want it to do that, but this one did what
we wanted to do. So the relative sales look good. So let's go back and say, okay, let's delete these
two and do it again, double-click on that 200. We don't want that 4% to move
down. That's in cell B3. Put our cursor in B3,
F4 on the keyboard. Or you can simply type
in a dollar sign before the B and three,
making it absolute, you only need a mixed reference, but an absolute
works telling Excel, don't move that cell
down, don't you? Don't you don't you move
that cell down, excel. Alright, so now we're gonna go and we're going to
select these two and will auto fill it on down
and putting our cursor on the autofill handle,
dragging it down. And I'll be confident going
all the way down before I double-check it and then I'll
double-check this last one, see if it does what
we think it should. It looks correct.
It looks correct. Just like I knew it we
knew it was going to do. I was totally confident. Okay. So now let's get down
to this bottom line would be up to 6,843 at the end
of the eight years. And we can see how the
interest is compounding, which is useful with regards to the interest table
calculation here. Let's go ahead and
hide some cells now. So we'll put our cursor on D and let's scroll
on over to G here, even though you can't
see, I think that's a G. Know my alphabet. What right? Then let go and right-click and
hide those cells. So we got, we got the data
input right next to the data. And now let's do the same
thing with the future value, which is going to jump
right to that in number but not give us that
nice running balance. That's why you probably
want to do this one. And the running
balance together in practice would be the ones
you'd want to use in practice. And then the tables
in the formulas is probably what you would be forced to use from time to time if you're in
a test situation, in a school situation,
we're then gonna do this. We're going to say
this equals the f v. And we can double-click on
that or simply say shift nine, which is all the more
urine away from the mouse, the geekier you are, which is what we're
shooting for here. So left, left, left, down. And then we're
going to say comma. And then we're going to
get the number of periods. So the number of
periods is left, left, left, down, down,
down, down eight. And then comma. And the payment,
that's going to be, if we had an annuity, this is not an annuity. We don't have a series
of payments we're putting into the
savings account, but only one payment that we're expecting to compound
over periods. So two comments here. And then we got left
down, down, we, it shouldn't go and
left and then up 5 thousand and enter. I
don't need to close it up. I'm just going to say Enter. There it is. I think that's
the same number, pretty sure. But it's negative. I don't want it I don't want it
to be negative. So let's double-click on it. We could put a negative in front of the present value here. Or we can put a negative
in front of the f, which I like to do, which
probably isn't as proper. But it flips the sign of the
entire function, like so. And I think it's easier
to do personally. So now let's do the same
thing with the tables. Remember that the tables
would really only happen oftentimes they
were great before, before we had the computer and the financial
calculators and whatnot. But now you've
probably used them in a school setting when you have the maniacal
teacher that does, takes away your calculator
and Excel and acts like your work in a cave with chalk. That you got it, rock that's
not even got a good point on it that you're trying
to scratch into the side of the wall. Then we're going to say
that we got 4% 8 periods. So 4% 8 periods down here, we're going to say
this is gonna be the 1.36861.3686, 1.3686. And let's add some decimals. So we can see that number, Home tab number,
adding some decimals. There's only four of them. And notice that the tables
are limited in that way. They will be rounded. And we go to the Font
group underlying amount. And let's multiply this out. This is going to be equal to up, up the 5 thousand
times the 1003686. And there we have it. There. This one happens
to be exact here. So notice if I add some decimal, I'm kind of curious if
I add some decimals and add some decimals. So it's still a little bit off if you add the
decimals to it. So remember that. Test question can use that. Like if you're in
a school setting, you say, Look, I'm not, I am not a caveman. I don't need to use the tables. I have Excel. And I'm going to,
I'm going to use it. And then you do it
this way and you get the more exact answer. They can still see that. They can say, Well, you
should have got this 6,843 because we told you to use the tables and you didn't you got
something different. So we know that you didn't do it the way
we told you to do it. And that can be
something that they can differentiate on a test question
or something like that. So remember you have to
use the multiple methods. One, so that she can do the
test question properly. And two, so that you
can understand what other people are doing if
they use a method different, the method that you're using. So let's go ahead and
hide some cells again. So we have the column K
right next to our data. So we're gonna put
our cursor on H, left-click and drag
on over two j to j. Let go, right-click and hide. So now we're gonna do it
with our formula down here. Straightforward formula, future value equals the
present value times one plus r to the n. We're gonna do that instead of just plugging
it in algebraically, we'll build our table type of format over here
as we do so we're practicing doing
financial statements or tax return format, which is highly
useful in my opinion. So we're gonna go ahead and these two components we're going to put in the
outer column here, sub-categories we want
to put inside with a colon and with an
indentation possibly to indicate that it's gonna be a subcategory as well and
bring into the inner column. So we'll start off with
the present value. Present value, which is
this term right here. You got to put that
in the outside. It's gonna be 5 thousand. I'm not going to
type it in here, but rather say equals left, left, left, left, up, and enter. And then we're gonna
do the other side, which is gonna be the
one plus the rate to the n periods one plus. Notice here I have a colon here, meaning I'm going to pull
that into the inside. So I'm going to say one. And in the rate,
I'm going to say rate is going to be equal to because I'm
gonna pull it from there. The cell over here. I
could type in 0.04, but I don't want to type
it in there because I want to pull it
from the dataset, want to pull it
from the dataset. That's good practice,
that's good Excel practice. That's how we should do Excel. And so then we're gonna go to
the Home tab number group. We could add decimals to make it 0.04 or we could
make it a percent, percent ties in it, which isn't an actual word, but I think it should
be we should percent ties did in Excel,
it's been percentile. And then we have
one plus the rate. And we can use the
trustee some function. Remember that this
one of course, if we made it into a percent, would be number group
percentile is 100%. 100% plus the 4%
subtotal equals the SUM. Sum function gotta
know what shift nine I would do it without, without using the
mouse if possible. Up once holding down,
shift up again. We have our, we have our items here and then
we could close it up, but we don't need
to and just enter. There's the one we need
to add some decimals, Home tab number of deaths and analyzing
or adding decimals, which could call
desk normalizing it. Although again,
that's not a word, but I kinda like it 1.04%. Or if we make it a percent
by percentiles in it, 104%, then we're going to
take that to the power of n. So it's gonna go to n in
periods of say, periods. And that's going to be eight,
which we could type in, but we need to take
it from our data on the table to the left. Because that's how we
do things in Excel. That's how things are done. Home tab, font group underlying
that allows us to run different scenarios if
we so choose easily. And this is going to be
one plus the rate shifts, nine shifts six to the n
periods, shift nine periods. And hopefully I
spelled that right. And this is going to
go to the outer column because we finished
off this thing now. So now this is going to
go to the outer column. We're going to take the 104% to the power of eight
equals left, up, up 104% shifts
gives us the carrot left and up to the eight periods and enter. There, we have it. Let's add some decimals
there by going to the Home tab number group
and adding decimals. And then I just add
a bunch of decimals, I call it destiny
normalizing it. It's been destined to mobilized. And then we're gonna go
to the Home tab font. That's not a word. I know. I know. But it's still
think it should be. So then we're going to
say the future value is going to be here. And we can now multiply
these last two out, multiply these last two. This is going to be
equal to up, up, up, up, up the 5 thousand
times that desk normalized thing that we did. And that gives us this
843 adding some decimals. There's, this should be
a more exact answer. There we have it now notice
that this number right there, the 13685 should be
what's on the table. So if I go to the
table, what was it? 4484 per cent eight. And we get 4% 8, we get the 1.36861.3, and then they rounded
it to four digits. You can see there.
And that's what the differences with the
rounding difference. This is how they got
kind of a table, but they cut it off
to four digits. So then we can unhide this
by going to the b up top. Left-click, drag on over
h or K, that's the K. Right-click and unhide. So now we got the 6,834
from the running balance, 6,842.85 from the future value, which is exact number. There's 6,843, which is a little bit different due to rounding because of the tables. And then the 6,840 to 85, which should be more exact
for the actual finance, for the actual formula. And then of course, we've got a running
balance to show us the yearly interest
that has been accumulated upwards as well. Note the yearly interest
is often useful for these kinds of calculations because they might have
a tax impact as well.
6. Future Value Annuity Investment vs Non Annuity: Personal finance practice
problem using Excel, future value annuity
investment versus non annuity. Prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information on the left-hand side going
to populate that into the blue area on the
right-hand side, comparing and contrasting two different investment
type of scenarios. One in which we have the one investment that
we're going to say is compounding interest annually to see where we will be
at some future point. The second, we're
imagining we're putting more money in each time period. That would be the annuity
type of situation to see then where we will
be at some future point. So first one will be similar to what we
have seen in the past. We'll probably do it a
little bit more quickly. Therefore, as we then
move on to the new thing, the annuity thing, the
investment of the 1 thousand, the years, eight years, the return we're gonna say
is 11% annual compounded. Where will we be
then in terms of future value after the
eight year time period, then we'll compare that to
an investment each year of 1 thousand for eight years
rate of return at the 11%. Now note that these two are
not comparable in that, in the sense that we're putting much different dollar
amounts in for both of them. The first one we're
putting 1 thousand in, seeing the growth in
terms of interests. The second one we're
gonna be putting $8 thousand in over eight years. But we have the comparison
between an annuity kind of situation and a future value
of one type of situation. Okay, let's start off
with the first one. We'll do this a bit more quickly because we've
seen this once, a similar one in the past to it. So we're going to have
our number of years. We'll do this with
a running balance, then with the functions
and Excel than using tables and then using a
mathematical formula, Let's start off with
a running balance. So I'm going to say 012. I'm going to copy that down. So I'm going to
select these items, gonna go to the autofill handle down below and drag that down. We're gonna do this a
bit faster this time. So bear with me. If you wanna do it slowly, you can take a look at the
prior practice problems and will slow it
down a bit there. We're gonna go to the Home tab. We're gonna go to the alignment. We're going to indent it. And then we're going
to be calculated. And this, I'm going to call
this the interests here. I'm going to call it an increase because it could be
interested in it could depend on the type of
investment as to what that increase format
will be looking like. The investment amount is
going to be equal to, we're going to pick up the 1
thousand at time period 0. And then we're going to calculate the interests
which will be about 1 thousand times the
11% in the first period. So it's gonna be equal to write up the 1 thousand times the 11%. Now that 11% is
outside of the table, so I know when I copy it down, which we will do this time, the first time, I need to
make that absolute reference. So I'm gonna do that by
selecting F4 on the keyboard, putting a dollar sign
before the B and three, you only need a mixed reference, but an absolute
reference works telling Excel do not move that cell
down when I copy it down. All other cells that are inside the same table typically
will need to be copied down, which is the default, the default setting when
copying and pasting formulas. So this is gonna be equal
to the one above it, 1 thousand plus the
one to the left, which is gonna be the 110. That'll give us the 100110. I'm gonna go ahead and just
copy that down this time. I'm just going to
select these two. We're going to put our cursor on the fill handle and just
autofill all the way down, autofill it down
there, we have it. Double-click on the last one down here just to double-check, see if it does what
we think it should. It does indeed do what we
think it does need to do. And there it is. So we're at the 2304. If we do our running balance, we can see the increase in the interest
compounding as we go. Let's hide some
cells and then do it with the other formats here, including the tables and
the Excel functions. I'm going to put my cursor
on the D drop-down, going to drag to the left all
the way to D to G. Let go, right-click the selected area
and hide that information. And then we'll do
our calculation and the future value calculation. So we're gonna do
this with an Excel formula which will
take us right to that Indian balance equals
the future value FV. We can double-click on
the FV or hit Shift Nine. I'm going to try to do
this with the keyboard. All with the keyboard. We're going to say left, left, left rate that I'm
going to hit comma. And then we have the number of periods which is
going to be left, left, left eight on the periods. And then comma, there is no
payment because this is not an annuity but a
future value of one. Next time we will have an annuity and therefore
we'll be using that payment item which you might be asking
about at this point. Why don't we ever use that one? We haven't done an annuity. I don't believe
yet. If we haven't, then we haven't
used that one yet, but we will shortly and
you'll get to see that. So there we have it, the 2304. Let's flip the sign. By double-clicking on it, we can put a negative in front of either the present value. I like to put it in front
of the entire function. Flipping the sign to 200305. Let's do it with the tables. We should get to the tables. We can do the same thing here. This is what would
happen if you are doing it in a school setting. This is gonna be equal
to the 1 thousand they might take away your calculator, take away your Excel, and just give you this
table to work with. And we'll say, alright, do it this way. If we have two phi half to 11% 8 is what we're looking for. So 11% 8 periods. So 11% 8 periods is
going to be down here at the
2.30452.30452.30452.3045. And then we'll add
some decimals, Home tab number group, desk and normalizing it,
adding some decimals. And then we're going to say Home tab fonts group underline. And that'll give us our future
value as FV future value. Let's multiply that out. This equals up to the
1 thousand times, up one to 2.3045 to give us the 2305 matching what
we got up top. Let's do it again with
the formulas now. To do so, let's hide some cells, let's hide some columns
to get our data right next to where
we're going to do the input of the data. Putting our cursor on
the age drop-down, left-click and drag
it over to Jay. Jay, Jay letting go, right-clicking on the columns and then hiding those columns. Now we've got our data
right next to where we want our formula calculation. Now the formula bean, future value equals the
present value times one plus r to the n. I'm going to put that in a
table type of format, as we have seen in the past, trying to get the
outer column to be equal to these
two components. Any sub calculations on
the inside similar as to what you would see in a
tax return calculation possibly or financial
statement kind of set up. So we're going to
say this is gonna be the present value and
the outer column equal to the starting point of a 1 thousand will get
this sub calculation, which will be then the one
plus r to the n periods colon, representing that it will
be a sub calculation. We're going to save one. And then the rate is
going to be equal to, I'm going to pull this from
our data as we've seen in the past, the 11% enter, gotta make that a
percent so we can see it Home tab number, you
could add decimals, but I liked it, making it a percent Home tab, font group and underlying, let's do a subtotal here which
is one plus the rate using the trustee some function
equals SUM shift nine up, arrow holding down,
shift up again. To sum it up with the
keyboard and enter. Let's add some decimals there. Home tab font group
coupled decimals to get us to the 1.11 or percentiles it making it 111% will take that to n
periods then to n periods. And that's going
to be then periods of eight periods up top. Let's underline that by going to the Home font and underline. And that's gonna give us then
our whole subtotal here, which would be one plus
the rate shift nine, carat shift six,
periods, aperiodic. And the outer column. Then this is going to
be equal to lift up, up the 111% shifts six carrot to eight periods to
the power of eight. And then we're going to add some decimals here so we could see some more detail
Home tab numbers, adding some decimals,
deaths and analyzing it. And then we're gonna go to
the font group and underline. So there we have it and
that'll give us our n value. Finally, finally, I thought
we were doing this fast. I thought we were doing this. Okay, So this is going to
be equal to up, up, up, up, up the 1 thousand times the
desk denormalized number. And so there we have it. So there's the 2305
about once again. Okay, so now let's
do the new thing, which is to do it, to do this one down here and an annuity calculation
as a comparison. So we have the data repeated, repeated on the right. So I'm going to hide
all the columns from n all the way back so that we can just work with this
data over here. So I'm gonna put my cursor on n, drag all the way back. You don't have to
do this by the way, because the data is right here, but it might be a little
bit easier to do this. And then I'm going to hide,
right-click and hide. So there we have it. Now I have a little
bit of a problem. These two, these two
calculations that are now on top of each
other, but that's okay. We're looking at this
annuity calculation here. And so now we're on the
second set of data. It's the same as the
top set of data, except that now we have
this happening every year. So now we're imagining the 1 thousand being a payment that we're adding to our
investment each year. So we're saying, okay,
I'm going to put more into it each year. Kinda like if you're saving for retirement or something like that and you're adding
more money to it. And it's got interests that's compounding on at complex
things, making things. More complex, I should say. That's how English,
because I was one too. I'm not going to start off
at 0 here with the annuity. I'm just going to
start off with one and then drag this down. So we'll first think
of our annuity with regards to our table. Once again, we're
gonna do our table. We're gonna go to the Home
tab, Alignment and center. Now note when we think
about the annuity, oftentimes the first thing
we got to think about is usually like a
normal annuity. You think about the payment happening at the
end of the period, which kind of confuses things
because oftentimes you start the annuity with
the payment today. So you got to realize
that when you do the annuity calculation
that you're talking about, a series of payments
that happens at it come at a interval. And usually that interval is
at the end of the period. If you're talking years, it would be at the
end of the year. So we're not going to
start with period 0 here with an initial investment. In this case, we're going
to say the annuity happens. And that usually is
going to be again starting at the
end of the period. So I can put the
first payment here in either the payment column or the investment column
at period one. And I'm gonna say this
equals to 1 thousand. And then I'm going
to start calculating the increase or
interests if it was an interest bearing type of investment on that 1 thousand
starting in period two. Note if you're off, it's probably because
you're just kinda mess it up that first
interval, the first year. And you gotta, you gotta
take that into consideration when you're thinking about your actual calculations
and whatnot. And if you have a more complex
calculation where you have a starting point
that you're putting in and then the
annuity on top of it, then you can adjust
your calculation. Either saying that you've got that initial investment
plus the annuity or you can try to format or just the annuity so that the
annuity happens basically, the payments happen at the
beginning of the period. Okay? So now we're gonna, we're
gonna say then let's do our calculation for the standard annuity starting off here, this is going to be equal to
the 1 thousand investment. And then we're gonna
multiply that times the rate times left, left. I'm going to bring
it down to this 11 down here and enter. So it's gonna be
going up your one or two by that 110% again. And then we're going
to say this is, but we're also going to
have another payment. Another payment which I could pull from the left over here, or I could pull up above, because the payments are
always going to be the same. I'm going to calculate
this one a few more times before we simply
just copy it down. And then this one gets
a little bit more tricky when we do
our running balance because it's gonna be
the prior balance of the 1 thousand we had before, plus the new payment
plus the interest. So we can do that by saying the 1 thousand. Let's
do it this way. I can show you it could
be this plus left, left this plus left, that, or probably more
commonly entered. I'm going to delete
that as equals the one above it plus the sum, SUM of the two
items to the left. The sum of those two. So we're just adding
the two to the left and the one above it for our running balance is going to close it up. The brackets. For me,
there's the 2110. Then we can calculate
the increase again. And now of course we've
got another whole, another thousand
dollars in there, instead of just
the compounding of the interest plus the
interest compounding. So now it's going to be equal
to the 2110 times the 11%. Plus we got another 1 thousand
equals to 1 thousand. We will copy this down later. You can copy it down. So we'll cop, will do that soon. And this will equal the one
above it plus the sum of. And then I'm going
to say the ones to the left, holding down, Shift, selecting those two, closing
up the brackets and Enter. Let's do it again. This is
going to be equal to the 3,342 times the 11% Enter. This will be the 1 thousand
payment that we're gonna be making on an annual
basis, adding to it, This is gonna be equal to the investment we
had before plus the SUM some shift nine, left arrow. I'm going to select these
two holding down Shift, Control, Zero closing up. Let's do it a couple more times. This equals the
400710 times the 11%. This is going to be
equal to the 1 thousand. And this is going to
be equal to the one before plus the SUM shift nine, left arrow holding down Shift, Left arrow again holding
down Shift and zeros. They close up the brackets
and Enter one more time. This equals this two to
eight times the 11%. This equals the 1 thousand. This equals the one above it, plus the SUM shift
nine left arrow once holding down
shift left again, shift 0, closing up the
brackets and there we have it. Now I'm going to delete the
entire thing and do it again, keeping in mind that we want to basically copy this
whole thing down. How could we do
that? I'm going to select this whole thing. Delete it. No, it's okay. Because we're gonna
do it the fast way this time, the easy way. So this is going
to be equal to the 1 thousand times the 11%. Now right away I see that
11% is outside the table. That means I'm. Visualizing that I'm going to
need to make that absolute. I won't do it yet. And then this one is going
to be equal to the one. That one's not going
to change either. I can pull that from
outside the table. Again, the fact
that it's outside the table means that if
I need to copy it down, I'm probably going
to have to make that an absolute reference. And then this one is going to be equal to the one above it, plus the SUM shift
nine to the left, holding down shift left again, closing up the brackets. That's a complicated formula, but it's all within Excel. So if I copy this
down and say, well, what's going to go wrong here? I'm gonna select these
auto, fill it down. So if something went wrong
here because that moved down and something's
going to go wrong here. Because this moved down. I want to keep it
up to 1 thousand items outside the table. I need to make absolute,
in other words, so I'm gonna delete this,
double-click on R 110, that 11% in P7, put
our cursor and P7, select F4 dollar sign
before the P and seven, you only need a mixed
reference but absolute work. And then I'll do the
same thing for this one. This one's in the tape outside
of our data table here. So we're gonna say F4,
saying Don't move that down. I want that whole column that'd
be 1 thousand and Enter. Then I'll usually select
these three auto-fill at one time just to double-check
before I go all the way. And then I'm going
to double-click here and say, Does
it do what I want? It does, does it do what
we're supposed to do here? It does. Does it do what it's
supposed to do here? Indeed, it does do the thing
that we told it to do. So now let's put our cursor
on the auto-fill and drag it all the way down.
And there we have it. So we're at the ending
result, 115511859. The amount of payments
that we put in, of course, are the 8 thousand. So we actually put in 8
thousand every year to get and then we had
the interests that increase or whatever.
The increase is. At the 3,859, it'll depend on what type of
investment we have. Okay, so now let's do that the easy way with
the Excel function, which will jump to this
dollar amounts down here. But again, doesn't
give you anywhere near the detail of a running
balance table like this, which I highly recommend
being able to do even when you talk to financial people to help you out with it, they're just going to
get to this number. And if they probably don't
have a good visualization of what is actually happening a lot of
times in their mind. Oftentimes, table helps. Let's go ahead and hide these columns by
putting our cursor on R to V, the RV. Let's hide that. We're
going to hide the RV. It's kinda big to hide
the RV will go k. We're going to right-click
on it and hide it. Hiding the RV R2 V. Okay, so then we're gonna do the future value of the
annuity calculation. Here's where we get to use
that payment part now. So it's the same
starting point as the last future
value. Future value. You can double-click
or hit Shift Nine, and it starts out the same. So it starts out the
same, which is deceiving. But then there's a
twist or a difference. And then we're
going to say comma. So this isn't where
the twist is yet. Number of periods,
this is the same. It's still the same. Here's the twist, here's the difference, the
number of payments. Now we use it because the payment means that we have repetitive
payments that are happening each time for each of the eight periods that
we have assigned. So we're going to say right
now we have a payment, we get to use that thing. Then we're not going to use the present value
this time because you usually use one or
the other here and we have payment's not
a present value. So I'm going to just say
the payment that we have. And notice this is like a
normal standard annuity. There could be variance again, if you had a payment
at period 0, which we might talk about
in a future presentation, but normal kind of annuity. So we're going to
close this up and enter there. We have it. We have the same situation here where it's a
negative number. If I double-click on that, you could fix that by putting your payment amount,
making it negative, which is probably
the more proper way, but I'd like to just put a
negative in front of the f. There we have 11858
There, we have it. Now let's do it with a formula, which is kind of a
more intense way of doing because the formula
gets messy down here. So just note that if you're at a school that makes
you use this formula, then there'll be, there'll be an unkind if you have to do that in a test question
situation because, but we'll do it. We can do it, we can do it. So I'm gonna go ahead
and hide some columns. We're going to be hiding
from W to wi, wi, wi, wi. Then we're going to right-click
and then hide those. Okay, so now let's do this. So now we've got our formula. So here's a little
bit more complex looking formula
here it's going to be the future value equals
the periodic payment, which is $1000 payment
that is now not really the present value as P was
determined to be before, but periodic payments
times one plus the rate, which is the 11% to
the number of periods, which is eight minus one
over r, which is 11%. Now you could just type
this in algebraically. I'm going to try to build
our table with this. Again, noting that this is a complex formula to build
in a table type of setting. So I'm gonna kinda make a tax return kinda setting with it. Noting that I want
to have this to kinda components
that we multiplied together in the outer column. And then I would like to
have the numerator and denominator and more
complexity happening. On the inner columns. And that's generally how
you can basically put a longer kind of function or algebraic equation into Excel in a similar way
as you might seem like a tax return or unlike
financial statements. So let's just practice that. I know it's kinda tedious, but let's do it
because it'll be fun. So now we're going to
say we have the payment or the payments which are
gonna be in the outer column. This is going to be
equal to the 1 thousand. And then I'm gonna
pick on the numerator, which is gonna be
this item here. So I'm going to
pick the numerator. I'll just call it the numerator. And I'm going to say
that this is going to be the one plus r to the n. So I'm going to just
start off with one. And then I'm going
to type in the rate, which is R. I'm going
to pick that up by saying equals and make sure
we pick it up from our data. I'm going to basically
make that will make that a percent Home tab numbers. We could add decimals, 0.11 or percentiles
it and making it a percent 11% font group
and underline it. Let's put a subtotal in that
calculation right there. It looks like a good place
for subtotals sub TO tau using the trustee some
function equals the SUM, shift up, arrow holding down, shift up, again, hold it and
then close up the brackets. We don't really need to close up the brackets, but you can. And then we're gonna go
home tab number group. That'll give us 101.11 or
percentiles in at 111%. And then we'll take that
to the number of periods. Number of periods, which was n, otherwise known as n here. So we're taking that
to the power of n. That's where we are
in the calculation, to the power of n, n
power, which is eight. And then we're gonna
go to the Home tab font group and underline. And let's, let's
calculate that subtotal. Do the subtotal right there. It looks like a good
place for sub subtotal. So we're gonna take the 111%
carrot n, which is eight, equals up to 111, Shift six carrot
up once and enter. And then we can add
some decimals there and the subtotal Home tab numbers, dust animal lives in it. So we can see some detail by
adding multiple decimals. And then we're
going to say less. Let's just say less one for finally rounding out the
numerator here minus one. Then we're finally to
the end of this thing. That's gonna be the
whole numerator. Numerator for bringing this to the average column is
going to be equal to lift up, up this thing minus that one. Let's add some decimals
there, Home tab numbers, bunch of decimals, otherwise
known as just normalizing. So has been mobilized. And then, so now I'm gonna
do some indentation. Let's go ahead and indent these. Let's select these items. Go to the Home tab
Alignment indent, and we can indent
this one and then this one's going to
be indented again. Let's go to the Home tab
Alignment and indent this again. So there's the numerator and then we have
the denominator, which was simply the rate. Let's pick up the rate which
is 11%, equals the 11%. That's this amount right
there. There's the rate. Let's make that a percent. By going to the Home
tab Numbers Group, we could add decimals. There's the 11 or
percentiles it, and then go to the Home tab
font group and underline. And that'll give us then, let's call this a subtotal. Subtotal, which is the numerator
divided by the denominator, which we're going to
put in the outer column so that we can then multiply p times this whole thing
that we just calculated. So we'll put this in
the outer column. This is going to be equal to the num divided by
the denominator, numerator over the denominator. And then we can add some
decimals by going to the Home tab number group
desks and normalize it. Then that's gonna give us the future value of the annuity. There it is. There
it is. Right there. Hold on to say, let's
multiply this one up top 1 thousand times, which was p, the number of
payments times his desk normalized number
that we came to. And that'll give us
the 11859 about. That was good times. Good times. So let's do it one more time
this time with the tables. So let's hide these cells
and do it with the tables. Now I'm going to
hide from z to this a D. I think that's
gonna be a d over here. Right-click. We're
on the double. We've worked so many things
that were on two letters. That's when you know, you're
doing good work right there. When you're all the way
out, all the way out past when you've cleared the
whole alphabet of work, we've been clear in
the whole alphabet. So then this is going
to be equal to the 1 thousand will pull this
amount up from the table. Remember that you've
got to make sure that you're picking up
the right table. That's gonna be the,
the key component here, future value of an annuity as opposed to future
value of one. And you'll see it because
it will of course be compounding a
lot more quickly. Down here you'll
see bigger numbers in the meat of the table. So we're going to be
picking up then our data which was 11% in eight years. So we're still on, the periods are in years
and the rate is in years. So we're going to say, I
forgot already, 11811, 8% down here, that's gonna be the
11.85911.85911.8591.85911.859. Let's add some decimals, Home tab numbers coupled
decimals there, 11.85985911.859. And then that's from the table. And that's gonna give
us our future value, future value annuity t, which is going to be equal to 1 thousand times
that table amount. And that gives us our 11 859, which is pretty much
what we got before. So what's underlying that?
And there we have it. Let's unhide this
and just recap it. So I'm gonna, I'm gonna select from all the way over and see if I can
unhide the whole thing. Right-click and unhide and see if we didn't do everything
should come back. We didn't delete it. So it should all be there
still. There we have it. So we did our
original investments with the annuity calculation. We got to the 23052305 with
Excel 2305 with the tables, 2305 with the formula. And then we did the annuity, getting to the bottom
line of 11859, running balance,
although it's a bit more complicated to do
the running balance, I think it's really
worthwhile to do. We have the future value of an annuity using
that payment cell. Now still get into the 11859. Then we did it with a formula, get into the 11859, and then we did it
with the tables, get into the 11859.
7. Investment to Meat Goal Present Value: Personal finance
practice problem using Excel investment to meet a goal or objective with the use of present value calculations, prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab, in essence
being an answer key, we have the information on the left-hand side and a populate that into the blue area
on the right-hand side, we're looking at a scenario
where we're trying to meet a future financial
objective goal. And we would like to see
how much we would need to invest at this point in time given a fixed rate of growth to meet our future
investment goal. Now, note, we're
not talking about a series of payments
at this point in time, which would be an annuity
type of calculation in which we may talk about in a
future presentation, but rather a lump-sum
that we would put in to some investment
at this point, that if we assume to
grow at a fixed amount, will reach some
point in the future. So we have our information, how much would we have to
invest to have in the future? 2400. So we haven't objective
in the future of 2400. We can imagine we're
buying something that costs 2400 in the
future at some point, how much would we have
to put in today if we expect to get a rate
of return at 6% and have that grow for
five years compounding annually to then get to
the goal of the 2400. Again, we're not putting
in 2004 we're not putting an amount in annually
or anything like that. Just one lump sum today
to grow at annual rate 6% to get to the future
amount of the $2400. Now of course, the investment could be various investments. We might have it in
a savings account, you might put it in a CD. Same kind of calculation for any of them that
might be in stocks, it might be in bonds or whatnot. Same calculation, although
the kind of income might differ if it was
in stocks or let's say a savings
account and whatnot. So that's gonna
be our objective. Now when you think about this, the first thing you
might think about, well, it looks like
you're looking into the future trying to
get to that 2400. So oftentimes it's a
little confusing here. This is actually a
present value type of calculation because what
we would do is take that 2400 and bring it back
to the current point in time in order to basically see how
much we would have to put into day to grow to that
future point in time. But because we're looking
into the future, you might, your first thought
might be future value. And if you plug this into Excel, you could use the
future value in first, think about that and then
say, does that work? Then try to figure this out. So that might be
your first step. You might say, let me
put that data to say a future value type
of Excel function, which will look
something like this, equals the future
value, shift nine. And then we can
pick up the rate. They have a rate argument, we're going to say,
yeah, that makes sense. We got to rape comma the number of periods
where you're like, Yeah, we've got
number of periods. That's gonna be five. Comma the payment. We don't have a payment because it's not an annuity
we're making we're just wanted to make one lump sum payment at the beginning. So I'm gonna put two
commas there and then we need the present value. And the present value
is what we don't know. And this is the area
where we'd say whom? That's the piece that I do not know because this
amount over here, the 2400 represents
the end point. That's where we need
to be in the future. What we don't have is the starting point,
the current point. So you could use say Goal
Seek to then figure that out. We could say, okay,
well, I'll just put that component down here, the present value down here. And I'll make that my
investment amount, and then I'll populate it. So I'm going to say Enter. And then I can guess my
investment amount like a thousand down here to
start off with and say, okay, so now I got a thousand, I'm gonna make this
number up here, a positive number instead of negative by
double-clicking on it, you could put a negative
in front of the p, or you could put one
in front of the f, like, I prefer to do. Put one in front of the f. Probably not the
most proper way, but the way I like to do it. And then I can ask Goal Seek, I could say, well, I could
change this cell and say, well what if I made this like 1200 or something like that? And then change this until
I get to the proper answer. Or we can ask Excel to do that. We can say, alright, Excel, would you go to the data group? We're gonna go what if analysis, what if Goal Seek, will seek the goal
here and we'll say, all right, let's just see if
Excel will make this cell. I want to make that cell
what it needs to be, which is the future value, what I'm trying to get
to, which is that 2400. So I'm going to type in
two for down here by changing then what's in
this cell, the 1200. So we'll say, okay, and Goal Seek does that. And it says there's the
1793 and there's the 2400. So that's one way you
might do it because you might first think of that future value
and then you'd say, you know, that kinda makes sense that it's
the present value. Because if I'm looking
into the future, I'm trying to present value
of that back to today. Because if you present
value back to today, that would mean that
if you started with that value and you
earn 6% a year, that's where you would
end up in the future. So it's really just a
present value calculation. So we could do that
same thing here, which you might realize once you see the unknown components
who are like, well, why not try a present
value calculation where we can say equals the
present value shift nine. Rate, once again
is the 6% comma, number of periods
then is going to be 55 years that we're talking
about comma payment. There is no payment
because we're not talking annuity here. We're still talking about
present value of one, so comma, and now we have
the future value, which we have the future value, that's where it
is in the future. We're bringing it
back to the present. And that's in essence
what we're doing here. So I'm going to take
that future value. There it is, and enter
there we haven't. So yes, the present value calculation to bring
it back because if I invested then 1793 at
the 6% for five years, then I would end up with
the 2400 in the future. That's gonna be the idea. So
if I double-click on this, making it a negative by either putting a
negative in front of the future value or in front of a P, which I'll put
in front of the p. There we have it. Now, of course we
can do, now that we know what the present value, we can do the same present value calculations with a formula, we could do a running
balance kind of thing to confirm our calculation and
with the use of tables. So let's do that
to round this out. So I'm going to hide some cells. We can see our formula right
next to our data input, putting our cursor on the sea, dragging over to E, letting go right-click and
hide, hide those cells. We've got our data input
right next to our data. And now we'll take
this calculations. It's just a simple present
value calculation which equals the future value times or
over one plus r to the n, which are going to put in a
table format where we want the outer column
to be representing the numerator and
the denominator. Anymore subcategories
like a tax return or financial statement we want to indicate as a sub calculation. So I'm going to say,
all right, let's do the future value, FV, future value outside. We don't want to
make sure that we're pulling this data from the table on the
left equals left, left, left that 2400. Then I'm gonna do
a sub calculation which is going to
be the denominator, which I'm going to call the
one plus r to the n colon, indicating that this is gonna be a sub calculation pulled
into the inner column and indented to indicate that sub calculation
it's gonna be one. And then the rate is
going to be equal to 6%, which we're not
just going to type, but rather hit equals. Scroll on over to
that 6% and enter, making that a percent. By going to the Home tab
up top number group, you could decimal lies it adding decimals or hit the percent, moving the decimal
two places over, adding the percent font
group and underlying. Let's do a good
old subjects here. Subtotal, subtotal. So we're gonna be adding
the one plus the R before we take it to
the n. So I'm gonna say this equals the sum Trustee
some function shift nine up, arrow holding down,
shift up again, and enter trustees
some function. Let's go to the Home
tab number group desk normalized at 1.06, which if we present ties 106%. And then we're going to
say that this is gonna go to n periods. Periods taking it to the
power of n. We're going to take it to the power of n. And n is five periods in
terms of years. So we're going to say this
is gonna be equal to five. Taking that from
our table up top, Let's put an underline there
by going to the Home tab, font group and underline. And this is gonna
be our whole thing, which is the one plus r shift 0, shift six carrot to the n
periods, pure shift nine. And now we're going to
put this on the outside. So this is gonna be
then equal to the 10, 6% to the shift six
carrot to the power of, in other words,
n, which is five. Let's make that some
decimals by going to the Home tab number
group desk and normalizing it by adding
decimals is what that means. And then font group
and underlined. It's not a real word by the way, but it is still a good word, even though it's not real. And then present value, we're gonna go over here. And then we're going to say
this is going to be equal to the num aerator divided
by the denom a nadir. And there we have
it, the 1793 about. Okay, so now let's
do the same thing with a running
balance calculation. So we can, we can, now, now that we have this
starting point number we can do are running
balance calculation. Notice we couldn't
do are running balance calculation to back in from the 2004
into that number. But now that we
have that number, we can kinda prove it
in our minds by saying, Okay, does that make sense
to me that I got that 1793? Let's do a running balance
calculations starting there and see if I do
indeed end up here, as I would expect to see. So let's hide some
cells to do that. Putting our cursor on F, we're going to drag on over to I phi and then right-click, and then we're going
to hide those columns. Hide the columns. Let's do our running
balance calculation. This balance is running. This is a running balance. Better go catch it
because it's fast. So we're going to say this
is gonna be equal to 101. We're going to
auto-fill that down, selected these two cells, putting our cursor
on the fill handle, dragging it on down to five, center in that home tab
Alignment and center. And this, I'll just call
this the increase in caries, which may be interests. And I may not have done this
on all of the problems. I apologize if I have
the wrong name up top there and I called it
interests when it wasn't, but I'm sure I'll hear
about the horrible, horrible error that was made, but it has been corrected now. So note that it's
been corrected. Okay, so now we're
going to start with our starting point here, which I'll just
calculate it again. This was the investment amount which will take as
the present value. Let's do the present
value calculation again, negative present
value, shift nine. And then I'm gonna take the
rate which is the 6% comma, and then the number of periods, which is going to be the five
comma comma future value, which is gonna be
that 2400 and enter. So there's our 1793. I just did the same calculation.
I know I did it quickly. You could pull it from
the prior presentation or the prior calculation
that we just did, but we just calculated
it again up top. So that's our starting point. Now, if I calculate the
interest at 6% for five years, I would expect the
ending point to be that 2400. Let's do that. We're going to say this is
gonna be equal to the 1700s, three times the 6% for period
one. And there's the 108. And then I'm gonna say this
equals the 1793 plus the 108. Let's actually just
copy this down. We've seen this type of
calculation in the past. So to copy it down, note that if I double-click
here that 6% needs to not be moving down because
it's outside the table. And I want to just copy this
down right off the bat, right away, off
the bat Home tab. And then we got,
so this is gonna be before putting our cursor and before F4 puts the dollar sign
before the B and the four, you only need a mixed reference, $1 sign, but an absolute references
easier to think about. So we'll say enter. We'll select these two and
put our cursor on the fill handle and drag it on down.
And there we have it. So now you've got the interests
increasing as we go down. The ending number does
indeed get us to that 2400 making us say, I
think we did do that. I think we did do it right? I think this is the way
you're supposed to do it. The present value is the thing that you're
supposed to use. Let's do it one more time
with the tables here. Tables are gonna be equal to the two thousand, four hundred, two thousand four hundred. And we'll pick the
amount up from the table which
you'd only be doing. If you'd, most likely if you're in a school
setting where they take away all the other
neat and fancy stuff that you want to work
with and give you this sheet of paper and
like chalk with it. You're supposed to
look up on the table. So then we're going to
say that that's gonna be six per cent and five years. So we're gonna say 6%, 5 years, which is gonna be 0.7473. So this is gonna be 0.7473. Let's add some decimals by
going to the Home tab numbers, adding some decimals
underline it, Home tab font group
and underline. And this is going to then
be our present value. Present value calculation then is equal to the 2400
times the 0.7473. And there's the 179, 41794 approximating
this answer up top, it is an approximation due to the tables round
into four digits. Let's unhide some cells
just to see that. How, how about
approximation comes to be? So I'm going to unhide
from BTK selected my Selecting be left-click, scrolling over to k bk,
right-click and unhide. Getting our, I think I hit,
I'm gonna do it again. A to L. I hit the wrong button. I hit the wrong button. You probably did it right. But I'm gonna do
it again. Unhide. Unhide. I'm not hiding things, I'm unhide and things. So then if I go over here, this calculation right here could help us to figure
out what the table is. Now that you've got to do
one more step to figure out the table amount which
would be equal to, it would be the 1793
divided by the 2004. Adding some decimals
Home tab number. If we add some decimals
there, there it is. If I, if I'm going
to go ahead and make this a permanent piece of
our of our practice problem. So it should be the 0.7747258. And over here we had 0.7473. They rounded it right there, which results in that
slight difference. Not, not important
or not usually, not usually going
to be impacting your decision-making process
in real life and practice. But again, a maniacal test person could try to take
away your calculator and make you use the tables. And then they would know,
they would know that if you didn't do it because
of the rounding difference. So you gotta be careful of
that and test situations. And again, you really
just want to know multiple ways to do these
calculations because that'll give you
a better grasp of what is actually going
on by looking at it from multiple angles and
being able to see other people do the same
calculations in different ways.
8. Annuity Initial Investment Present Value of Annuity: Personal finance
practice problem using Excel annuity initial
investment calculation, using the present value
of annuity calculation. Now, prepare to get
financially fit by practicing that
personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information on the left-hand side
going to populate that into the blue area. On the right side, we're looking at
the general type of scenario where we are
thinking about wanting to have enough money in
an investment type of situation so that we
can be taking money out on a periodic basis
and thinking about having fixed rate of return for the money that is
still in the account. Now this is often
one that's gonna be more difficult for
us to visualize as to which tool we should
be using for this type of calculation because it's
something that looks like an annuity is an annuity, but it's something that
we're planning for it to be happening in the future. So we might think
it would be like a future value annuity
type of calculation. But in reality, it's gonna be a present value type of
calculation because what we're trying to do is
look at the series of annuity payments from a
present value standpoint, bring it back to
the current date. As of this point in time, think about how
much money we would have to put in at this point in time in order to pay out
that annuity portion. Let's see if this
makes sense here. Here's our information. How much would have
to be invested to be able to take out
each year, $500. So we want to take out each
year $500 for seven years. And the amount that's still
in the account we're going to assume is going to be
accumulating a 7% increase. So this would be a type
of thing you might do when you're doing
retirement planning or something like that and
you're trying to think about how much money
do I need if I was to take out so much per
year and the amount that I still have in there is going
to be increasing upwards. So that kind of scenario, you might have other scenarios in a similar type of situation. If you're planning for something that's going to result in a series of payments
that's going to be happening at some future point. Okay, we're gonna do our
present value calculation. Let's start it off with
a present value of an annuity in an Excel
function type of format. Then we'll prove that by
basically running the table, which is often a
great tool to kind of verify that we have our mind
wrapped around this thing. We're gonna do a
present value of annuity calculation
equals the present value. It starts off the same as
the present value of one. You can double-click on the
present value or shift nine. There is our function argument. We're going to pick
up the rate which is you could type in there at 0.07. I'm going to point to
the cell at the B64, the 7% comma number of periods, number of periods is
going to be seven. So I'm going to scroll down,
down, right down, down. I'm going a little bit faster
in Excel as we get used to using Excel hopefully
at this point. So then I'm going
to say comma again. This time we are using the
payment because this is an annuity calculation as opposed to the
present value of one, in which case we skipped the payment and went
to the future value. In this case, we have
the payment of 500. We're imagining that to
be repetitive payment, not just a onetime payment, that will be increasing by 7%, but one in which
case we would be putting it in each period. So then we're not going
to have any future value. So I'm just gonna leave
it there and enter, and there we have it. Let's increase the
size of this a bit. We're at the 2000s, 694. Let's make it a positive number
by double-clicking on it, we can put a negative in
front of the payment, which is probably more proper. I like to put it in
front of the p here. So there we have it. So we're at the 2694 now, you might have thought, well, if I would need 500
times seven would be the basic calculation
that you would need 3,500. But of course, you
don't need exactly 3,500 to be taken
out 500 each year. The return is getting 7% return. So then the next step is to
say, well, I don't know, let me double-check
that this number is correct by basically running that number in our
running balanced type of calculation over here. And if it's correct, if I start at that
investment point here, take out $500 each year, then am I going to end up at 0 at the end of
this time period? That's kinda what
we're looking for to see these two
things side-by-side. Let's go ahead and hide
that some columns here. I'm gonna put my
cursor on column D, drag over to column F, D to F def, and right-click and hide
those, hide those columns. And let's do this calculation
again. I'm going to say 01. I'm going to copy that
down to line seven, highlighting those two
or selecting them, putting our cursor on
the autofill handle, dragging down to seven. Then we'll go to the Home tab Alignment Group and center it. There we have it. Now, I'm going to recalculate
the investment again, doing that calculation,
again just to practice it. And negative present
value, shift nine, the rate left, left, left, left down, down, down 7% comma, number of periods
left, left, left down, down, down seven comma, and then the payment
left, left, left, left down, down to
the 500 and Enter. There's our 2695 about we're going to say that
that's going to be an increase for
whatever the value is that we're increasing it for. So if it was a savings account, it would be interest
if it was stocks, we're going to say the
value is gonna go up, we're estimating
by 7% and so on. So I'm going to say this
is going to be equal to lift, lift up 2695, about times the 7, 7% percent and enter. Now I'm not going to
copy it down yet. I'll do a couple of
these calculations and then we'll copy it down. And then I'll go back and make the absolute references
needed to do so. Then I'm going to make it a
negative for the payment. I'll make it a negative
here for the payment. A 500 because we're going
to take out 500 each year. That's the point. And at the
end of this we should end up at 0 if everything worked out
the way it's supposed to. So this cell we could be
sick equals the investment, the 22695 plus the
189 minus the 500. But because I put it
in here as a negative, I'm going to say plus
the negative number, which will be a
subtraction problem. So the 2695 plus
the interest earned minus the amount of we're gonna be paying out in the annuity. And there we have it now, I think it would be better
to calculate this one. I'm going to delete
that this way. This equals the one
above it plus the sum of the fact that this number is negative allows
us to do that nice. Some function of these two closing up the
brackets and Enter. Let's do it again. This
equals to 2383 times the 7%. And then this is gonna be
the negative of the 500. And then this is going to equal the amount above it plus the SUM some shift nine left arrow
holding down shift left, again holding down the Shift and 0 and enter
there, we have it. Let's do a couple more times. This is gonna be equal to
the 2050 times the 7%. Then 500 negative at the 500. And then this is
going to be equal to the prior balance plus the SUM, the sum left arrow
holding down shift, left shift 0, closing up the brackets and
Enter one more time. And then we'll do the autofill, doing it the easy way than to take this
item times the 7%. This is gonna be equal
to the negative 500. This will be equal to
the amount above it plus the SUM shift nine left arrow holding down shift
left again and enter. See I didn't close
the bracket up and it gave me a little error,
but that's okay. Then it fixed it.
So there it is. So now let's delete
it and let's do it again as if we're
going to copy it down. I'm going to delete
these and do it again as if copying it down. And this equals this
2695 times the 7%. And then the payment is going
to be the negative 500. And then this is gonna
be equal the one above it plus the SUM shift nine left arrow holding down shift and shift 0
to close it up. Now if I copy that down, selecting these items and using the autofill to copy it down. Then we'll see what
the problems are. So this problem here, it moved the 7% down. So we don't want, we
want to fix that. And this one got moved down
from the 500 down here. So those two we're going to fix. So I'm going to delete these
and I'm going to fix it by double-clicking and
anything outside of our table that's usually
what we need to fix. So this is in B6, I'm going
to put my cursor in B6, say F4 on the keyboard. To put a dollar sign
before the B and six, you only need a mixed reference, but an absolute reference works. And then I'm going to
put my cursor here, double-click on the 500. Once again, select F4 on the keyboard dollar
sign before the B, and therefore say an Excel do not copy that down and enter. Now let's copy it down again. I'm going to auto-fill it the whole way down this
time because I'm confident I'm confident that
we did it right this time. So there we have it and the
bottom line number gets to 0, indicating that,
yes, indeed this is the proper amount
that we calculated. So you can see how that worked. And then if I double-click on
this last one, we see yes, that doing what we
expect it to do, everything is doing exactly
what it's supposed to. Okay, so now let's do
this with a formula. Then let's do the present value of an annuity with a formula. I'm going to select
the cells from. Let's go from c to k here. I may be larger. I didn't want to make
below if I want to go to from C to j, C j, let Glo right-click
and hide those cells. Now let's do this with
our present value of an annuity calculation. So here it is, down here, this
is a long kind of formula. If your instructor or someone
forces you to do this, they're kind of mean because
it's kind of a long formula. But they might, and it might be worthwhile just
to kinda look at, look it over to get an idea
of what it looks like. Again, in practice, of course, you'd probably be using the Excel worksheets and I
think the running balance, those combination between those two will actually give
you the most insight. For what you're normally
going to be using these four. Alright, so we're
going to start here with the payment amount. So P stands for the
payment amount. Obviously you can, you can
plug this into this formula. The payment would
be the 500 times the one minus one
over one plus r, which is seven per cent to n, which is gonna be seven years
divided by R, which is 7%. I'm going to break this
out into a table format, which I think is good
practice just to do and just to build tables with like kinda
like a tax return format. And we know that
financial statements are similar,
similarly formatted. Notice this one is a long, ugly formula with multiple different
division components to it. And therefore we're going to have different subcategories. You might set it up a little bit differently if you were
to set up a table. But just practicing putting a long formula into this kind of table structure actually is fairly useful
oftentimes in practice. So I'm going to say,
Alright, the 500. My major thing is
these two components. I want to put these on the
outer side, outer column, and then I'm going to
bring a whole nother inner column for these two. And then this numerator
I'm going to bring even further inside
for a sub calculation, given them more detail there. Alright, so the payment
is going to be 500. I'm going to say
this equals the 500. And then I'm going to
call this the numerator, which is not an exact Item. I could actually list
out the numerator, but I'm going to call this
the whole numerator up top. And notice it's one
minus this whole thing. So I'm gonna put down
here just one in this inner column because once I'm done with this numerator, I'm going to want that to fall
out into the outer column. And then I'm going to call this, and I know this is kind of
a convoluted item here, but it's going to
say numerator to, which I'm going to indicate
as this one right there. So I'm just going to
indicate that as one. I'm not going to
put a colon because it says just gonna be the one. And then I'm going to say
the one plus r to the n, which is the denominator of this hierarchy little
component here. So I'm going to say this
is gonna be one plus r shift to the
carriage shifts six, n is gonna be then I'm
going to put this on, and I'm going to put a colon
on this one because there's, so I'm going to bring
it to the inside again. This is going to be one, the rate is going to be
then the seven per cent. So let's call this
just the rate. The rate is going to
be equal to the 7%, bringing that into the inside, Let's make that a percent go
into the home tab numbers, making it a percent font group. And then underline,
I'm going to call this a sub calculation. So this is a sub
subtotals sub TO tau. I'm going to use the trustee
some function equals the SUM shift nine up arrows
holding down shift up again, and then closing that up, making that a percent Home
tab numbers per cent to find it 107% that I'm going to
take that to the power of n. So I'm going to say
this is going to go to the periods n period in periods, in other words, which is
gonna be seven periods. So this is going to go
to seven periods, seven. And let's underline
that by going to the Home tab font
group and underline. And that's gonna be this
whole subcategory calculation which was one plus r, and then shifts to the n, which I'm going to put it
in the outer column now. So now we're pulling this
to the outer column. This is going to be
equal to the 10, 7% shift six carrot to the
seventh power, power of n. Let's add some decimals there. We're gonna go to
the Home tab number, group and desk denormalize it, just adding a whole
bunch of decimals. And so there we have that. Then we could indent
this whole thing. Let's go to the
Home tab Alignment, indent, indent,
this whole thing. Home tab Alignment, indent, and then indent this one again, Home tab Alignment and dent. And so there we have that. And then we've got,
I'm going to call this a subtotals sub, subtotal, which is gonna be
this whole thing right here. And I'm going to pull that
into the outer columns, put an underline here,
font group and underline. And now I'm going to
subtract this column here. So subtracting this out, notice I'm only doing
something to the left or right above in our calculations, this is gonna be
equal to the one divided by now the
1.605 and so on. Adding some decimals
Home tab number group, Let's destiny
symbolized that number. So it's been desk normalized.
So there we have that. And then we can pull
up the denominator, I'm sorry, then we can
get the full numerator. So this is going to be
the numerator torr, which is gonna be this
whole thing now one minus that thing underline here, I'm going to go to
the font group and underline, subtract this out. Notice I'm in the same column. This colon might indicate that I could have
one more column, but we'll do this
in the same column. This is going to be equal to the one minus one
minus the 0.622750. Adding some decimals there, Home tab number, group
desks and normalizing. So there we have that. And then we can take
the denominator, which is R here. So that's gonna be the rate. So let's pick the denominator,
which we'll just say, let's call it denominate
torr, or the rate. With the brackets around that, that's gonna be equal
then to the 7%, again, 7%, making that a percent by going to
the Home tab numbers, group per cent ties in it, font group, and underlining it. And then we have
our subtotal here. Let's call this a sub total, and we'll bring that
to the outside. And we'll divide this out. This is going to be equal to the 0.37725 and so on
divided by the 7%, making that a percent or adding decimals Home tab numbers
desk normalizing it. So there we have that
and that'll give us the present value
of the annuity. Finally, by taking
this component times this whole thing here, underlining this one
before we do Home tab, font, group and underlying,
multiply this out. This equals the item way up
top 500 times this 5.389. And so on. Adding a couple of
decimals there, Home tab numbers
coupled decimals. So there's our 2694 once again. So again, I know that was
kind of a long table type of worksheet and whatnot. So if you were to calculate this in practice in
a test question, it's can be kind of cruel again to make you do that
multiple times. And the Excel functions
are useful to do that. And of course you
could plug this into the formula here as well. So I'm going to hide this.
Let's look at the tables now. I'm going to hide from L to Q. Right-click on the selected
area and hide those cells. And let's do this
with a trustee table. So we're going to
say the payment, payment is going to
be equal to 500. Now, make sure you've
got the right table. We are talking about
the present value of an annuity table. And once we have that, we're
simply looking for 777, 7% periods or years, yearly percent yearly
years and periods. This is gonna be 775.38935.3893. Adding decimals Home tab, the number group, add
four decimals there. And this is gonna
be from the table. And let's underline
this by going to the Home tab font
group and underline. And this will give us
the present value of an annuity t. Let's just
keep it and knew at T, this will be equal to the
500 times the 5.3893. And we can add a couple
of decimals there. And there we have it. Let's unhide a few tables here or unhide some
of these columns. And then just recap what
we've got on hiding. And we're gonna put our
cursor from our column to be right-click on the
selected area and unhide. Then we can see that we got
this calculation at the 2694 with the present
value of an annuity. We double-checked it by starting there and then having the
annuity payments ending at 0, which gives us verification
that it was done properly. We then look at the present
value of the annuity. We get down to
that 2694 as well, noting that this amount is in essence the amount
from the table. This is the amount that she
could build the table from. Its more than four digits long, which means we have a slightly
different number here, the 2.65694, fairly, very close, but slightly different
due to the tables rounding to four digits.
9. College Savings Calculation: Personal finance practice
problem using Excel, college savings
calculation, prepare to get financially fit by
practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information
on the left-hand side, going to populate that into the blue area on
the right-hand side looking at a college tuition
saving type of scenario. So there's a couple of types of things that we would
commonly need to take into consideration when
thinking about college savings. One is we want to think about
how much money we're going to need when the college
basically starts. And then two, we've
got to think about the idea that the college
is kind of like an annuity. You would think that we can estimate how much
it's going to be costing for the time period
that we will be there, which would be like four years that we'd basically
be planning for. So we have two things
that are involved here. We've got once the
college years start, we have an annuity
type of situation where we would assume set cost that it's going
to be costing for, let's say, a four-year
time period. And then two. Once we know that
annuity amount, we can think about how
much we would need to be investing at this point in time in order to save enough to get to that to
that annuity amount, to get to the college
years point in time. Then of course, we can take into consideration student financing and other kinds of
things that would go into into play at that point. So at this time, were
trying to figure out how much would
basically college costs at the point
in time that college would start using our
annuity type of calculation. And we're going to
be assuming that the costs for college
are gonna be the 25 thousand per year for four years with a rate
of return at the 6%. So in other words, if we had
a series of annuity payments then for four years that are going to cost us
the 25 thousand, how much would we have to
invest in order to cover that? And of course, the first
calculation you'd say, Well, we would need then we would need the 25 thousand times four, which would be the 100 thousand. And I'm gonna make
that blue here, that 100 thousand total. But if we have money in
the savings account and during the annuity and it's
getting the 6% increase, then we don't need the full 100 thousand at the
starting point. So first we want to
think about how much we would need at
that starting point, the next step, and that's
what we'll work on here. The next step would then think about how are we
going to get to that, to that starting point number in terms of our savings as of today and or any other financing that that could be taking place. Okay, so we'll do now, this is a similar
kind of thing with this annuity type
of calculation, which seems a little bit one of the more difficult
ones to visualize in your mind because your
thing, you're saying, this is an annuity kind
of thing because this is, we're going to assume
it's a 25 thousand for four years even payment. But it's something
that we're planning to happen like in the future. So you might say that it
should be a future value. Annuity might be
your first guess, but it's actually
a present value of an annuity because we're
trying to figure out the annuity payments and
then bring them back to the amount that they would be at the start of the annuity. So to prove that, then we'll do a present value type of
annuity calculation, and then we'll prove it with a running balance type
type of calculation. And then we'll do
the other methods of calculating a present
value of an annuity. So let's start this out. We'll do this a little
bit quickly because we've seen some
similar problems. The difference here
is the scenarios that you want to keep in
mind that you can use these different calculations
for and be able to understand when you look
at different things that you're planning on
that are gonna be in the future and need to take into consideration time value
of money that you know, you can figure out which
tools to be using. We're going to say this
is gonna be equal to the present value, shift nine. We're going to pick up
the rate which I'm going to type in there at 0.06. But take that from the table. At the 6% comma, we're now at the
number of periods, which is going to be four. We're going to say for
bringing that from the table here and then comma, the payment, the
payment is gonna be the 25 thousand for each
of those years. And we are using a
payment because we're talking about the
annuity point in time. Once in college, we don't
have any future value. So I'm just going to leave
it at that and enter. Let's go ahead and make that a positive number by
double-clicking on it. And then I'm gonna
put a negative. We could put it in
front of the payment. I like putting it in front
of the present value. So I'm going to put
a negative here, flipping the sign to the 8667, six twenty seven, sixty four. So if if at the start of
college we plan on taking out 25 thousand each year and
we're generating six per cent. We should not need
hopefully the 100 thousand, but the 86627, given the fact that the amount that's in the savings account, hopefully we will be
making around that 6% of of interests or increase or whatever
value that we have, whether it be a savings account, where it would be
interest or it would be stocks or
something like that. Let's go ahead and hide
some cells and kinda prove that by doing a
running balance calculation, we're gonna put our
cursor on column D, drag over to column F. Let go right-click on the
selected area and hide them. And then we'll do our
running balance calculation. I'm going to put our periods
here by saying 01 and so on. Selecting those two cells, put our cursor on
the autofill handle and dragging that on
down to four periods, going to go up top
to the Home tab, the alignment group
and center that. Now our starting point, I'm going to recalculate
just to practice this again, this is gonna be
our starting point. And then we're going to imagine this annuity playing out and the end result should be 0
at the end of this process. So let's, let's
test that out and see if that is indeed
the case negative. Present value shift nine. We're going to pick
up the rate over here at the 6% same calculations. So I'm gonna do it
a bit quicker here. Comma, number of periods is gonna be the four
periods and then comma and the payment is going to be the 25
thousand, That's it. And enter there is our
starting point at the 86628. So if we had that at the
beginning of college and then we're saying
that this is going to be, I'm just going to
call it the increase instead of interests because it might not be a savings account, we might have it in
some other format. But whatever format it is, we're going to assume
a 6% increase. Now I'm going to try to do
this a little bit quicker. I'm going to plan as
we go to copy it down. And so any absolute references, I'm gonna do that
on as we go here. So this is gonna be equal
to the 86628 times. And then the 6%. Anytime I pick up something
outside the table, I'm going to think and say,
what am I going to need to make that an absolute
reference to copy it down? Do I want that cell
to move when I copy this down to the
relative Cell Below, the answer is I do not want it to move, and therefore, yes, I do need to make an
absolute reference, selecting F4 on the keyboard, putting a dollar sign
before the B and eight, you only need a mixed reference, but an absolute
reference will work. Then we'll do the payment here. The payments are all
going to be 25 thousand. I'm gonna make that a negative. And 25 thousand so that it'll show up as a
negative number, allowing me to use my sum function when
we sum them up on the, on the outer column here. So this one again is picking up something outside the table. When I copy it down, I don't want it to move down. Therefore, I need an
absolute reference here too. So I'm going to select
F4 on the keyboard, dollar sign before the B and the six. So there we have that. So now we want the 86628 plus
the increase for the gains that we're going to have
as this is still in an investment minus
the 25 thousand, which is the actual cost
we're going to have to pay for the college
on a yearly basis. So this is going to be
equal to the one above it. And then I'm going to say plus because and use
the sum function. And then as I sum these up, it's going to be adding one and subtracting the other due
to the negative number. Closing it up, shift
0 to close it up. And hopefully we've
done everything we need to do to
now copy it down. So I'm going to select
these three cells, put our cursor on
the fill handle, drag it on down. And there we have it at
0 at the end of the day. So that kinda proves that our present value
calculation is correct. We have 86628. If everything goes well, we can spend the
25 thousand each year and still have
enough instead of having 100 thousand
due to the fact that whatever still in the account's gonna be generating that 6%. When you're doing a retirement
type of calculation, you typically have a similar
kind of thing in mind. You've got a big chunk of money that you're trying
to and nibble at over time without having it go away and still earn interests so that she
can live on the thing. So now let us do it in the calculation with
the formulas over here. So we'll do the same
calculation with the formulas. And this is more of a
complex formula to do so hopefully they don't make you do this too much in a classroom, but they probably will at
least introduce it to you. So we'll do that by putting
our cursor on column C, dragging over two j, C j. And then right-clicking,
we're going to, we're going to hide those cells were doing this calculation. So you could simply plug the information
into this formula, which would be the payment, which would be the 25
thousand times the one minus one over one plus r, which is 6% to the
number of periods, which is n, or four
divided by r, which is 6%. Again, we're going to use this opportunity to
make a complex table, given the fact that this
is a complex formula with two division
components in it. And see if we can build
basically a table. On. The table doesn't
need to be perfect. But practicing putting
something into a table format like
this is good practice. And so that's what
we'll use it for. This is the format. You might see a tax return in. The format you might see
financial statements in just building the
table can be useful. It's also something that you can use if you're basically having a similar calculation that
you want someone else to use. And you want to
make the data input screen an easy data inputs grand or something like that. So we're going to say
we have the payment up top, picking up a payment. I'm going to put that
in the outer column using our strategy of having the two major components in the outer column and
then the inner column. I'm going to take the two
major components here, numerator, denominator
and the inner column. And then this numerator, I'm going to have to
break this thing out as well given the fact that
it's somewhat complex two, so this would be a
fairly complex thing to put it into a table. And so if you look
at tax returns, you have complex things
in tables that are in a similar format
like this, right? So this will be the 25 thousand. Then I'm going to call
this just the numerator. Numerator, and this is the whole
numerator, this whole apart. And notice I have another numerator kinda
subcategory here. I'm gonna put a colon
bringing this to the inside. I'm going to put over here
starting with just this one. I'm just going to put
one here because I got to have one minus
this whole thing. And then I'm gonna put
another subcategory which I'm going to call
the numerator 2s. I'll call it numerate
toward tour, to which I know is a funny name. But you can then
I'm going to say this is gonna be
one because now I'm in here in this
subcategory calculation. I'm just going to put
that on one line. I don't need a sub category for it because there's
only one number in it. And then the denominator,
which I'm gonna call, I could say denominate torr, which is one plus r to the
n, something like that. And so that's gonna
be the denominator. I'm going to put a colon for a subcategory on
the denominator, which is gonna be
one plus the rate, which is going to be equal
to the six per cent. So now I'm in here
one plus the rate 6%. I'm gonna make that a percent
Home tab number group per cent to fight it. Font group underline it. Then we'll put the
subtotal here. So subtotal, subtotal and sum that up equals the
good old SUM shift up, arrow holding down,
shift up again. Let's make that 8% by
going to the Home tab, font group, or number of
group percent define app. The 106 per cent will take that to the number
of periods or n. So I'm going to take that
to the periods, periods. No one as n, which is
going to be four periods. Four periods. Let's
underline that home group, font, Home tab, font
group underline. And that's called that
another subtotals sub total TO tau, bring that to the outer column. So this is going to
be the outer column. This equals the 106%
shift six carrot to the power of four. Let's add some decimal so we see some activity there by going to the Home tab number of
group desk and embolize in it, adding bunch of decimals. And it could keep on going, but we'll keep it there. And let's actually call this, this should be the,
we're going to call it the denominator here. So that's, this whole thing. Is Indian this kind of process. So I could indent these
selected this whole thing, Home tab Alignment and dent and possibly indent this
again, Home tab Alignment, indent again, we're going to pull this to the
average column, Home tab, font group
and underline. So now we've got this division
problem we'll do here. We'll pull that in
the outer column. So this is gonna be equal to, notice we're only working
in one column at a time. So I'm gonna be in this column
and then divided by this. This is standard kind of
financial statement formatting, oftentimes where you work
in one column at a time. And then we're gonna
go to the Home tab. We're gonna go to the numbers and some decimals
destiny analyzing that. So there we have that. So now we've got this
whole piece done. And now we're in this
outer column where we have one minus that whole piece, which will be the end of
the numerator calculation, which indicated by this colon, would think that we would
put it into another column, but I'm gonna keep this
in the same column here. So this is gonna
be the whole num, num or eight torr, which is going to be
equal to the one. We're working in
one column again, minus this thing which just
came to that decimal number. We need to add decimals
there so we can see it. Home tab number, group, desk and normalizing it. Let's put an underline
under this one, where we go font group
and, and underline. So there's the numerator, then the denominator,
which is the rate. So that's this denominator, the rate we can put
right underneath here, and that's gonna be the 6%. So we're going to
say 6%, they're adding that to a percent. Home tab numbers
per cent define it, font group underlining it. Then we'll call this a sub tote, subtotal, putting that
in the outer column, this whole thing
divided by this. So now we'll have this
whole thing done, which we can finally
multiply times the payment. Putting that in
the outer column, this will eat the num array ptr divided by the
denominator on nature, adding some decimals
Home tab numbers, desk minimizing it, underlining it by going to
the font group and underline. And finally, that'll give
us our present value of the annuity working
in the outer column. Now, we're going to multiply the 25 thousand, this whole thing, this thing times this whole thing that we just calculated, the 3.46 and so on. This equals then the
25 thousand times. 3.46 and so on gives
us about the 86628. Let's add couple of decimals, Home tab number,
coupled decimals. Finally, there we have it. Okay, I tried to correct some
spelling here and I tried to do the indentation
is a little bit, make sure we got those lined up. But now since there we got
it, we have that there. You can double-check
that on the answer key if you want to look at it
a little bit more detail, okay, and that's the green tab. Let's do this one more
time with the tables. So I'm going to put
my cursor on K here. And before we do just
note that this cell right there represents how
you build the tables. Notice it has more
than four digits, which will result in the
tables which are limited to four digits being somewhat
off in terms of rounding, which will not be
too bad for what our purposes are here
for decision-making, given the fact that
it is an estimate. But in practice or in a test situation,
they could use that. Remember, to distinguish
what you're, what you used to calculate. Okay, let's hide some columns. Put in our cursor on column K, dragging over to
column P, let go, right-click the
selected area and hide those columns and do it one
more time with the tables. So we're going to
have the payment, which is going to be
equal to the 25 thousand. We're going to look
for the tables now, 6% for year, 6% for years. So there's the 6% for years. Is that, by the way, make sure you have
the right table. We're looking at the
present value of an annuity table here. Typically you have
four tables to pick from present value
of an annuity, 6%, 4 years, 3.4651. So we got 3.4651
adding some decimals, Home tab number,
group, desks, animals. And then we're going to say
this is from the table. And this is gonna be the
present value of an annuity. We're going to say
multiplying this out 25 thousand times the 3.4651, putting an underlying Home
tab font group and underline, we get the 86628. Let's add a couple of decimals
Home tab number group, a couple of decimals there. He's got the 86, six,
twenty seven, fifty. Okay, Let's unhide some
cells and just recap here, putting our cursor on column B, dragging to our
right-click unhide. So we had the 25 thousand that we want
to take out each year, which if we didn't have any other earnings on it
would be the 100 thousand. We calculated that if we have a 6% earnings in the
beginning amount, we would need only the 86, we'd only need 86627, 64. And then we prove that by
basically starting that and having a running balance
which brings that down to 0, proven, proven the annuity. Then we've got in
this calculation, we've got the 86, six, twenty seven, sixty
four using our formula. And then we've got
slightly different number using the tables of
the 86, six, twenty, seven, fifty due to the
difference of rounding, because of this number is
rounded to four digits. That's the number that
came from the table. And if we look at the actual
number that we calculated or closer to the actual
number going more digits out. It's going to be different due to the rounding of
the four digits.
10. Retirement Savings FV of Annuity: Personal finance
practice problem using Excel retirement saving
calculation with the future value of
an annuity formula. Prepare to get financially fit by practicing personal finance. And we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information on the left-hand side
and a populate that into the blue area on
the right-hand side, we're looking at a retirement
savings type of scenario. Note that there's
two general kinds of scenarios that you'll set up in your mind when
you're thinking about the retirement savings. So in other words, if you're
thinking about saving over your earning years
and thinking about how much you would
need at retirement. You might phrase that one
way to say, Hey, look, I'm going to save as much
as I can at this point in time on a yearly
basis or periodic basis, and assume some rate of interest on that increased
amount that I'm going to put into a savings account or some other retirement account
and then try to determine, given an average rate of growth, how much we would
have at retirement, which we're going
to say in 40 years at this point in time. You can compare that
and contrast that to the other view you might
look at, which would be, how much money will I need at retirement in order to support my needs at the point of retirement after I'm done
with my earning years. Meaning you might then do
an annuity calculation at that point in time to determine how much of a
basically a nest egg, what big chunk of money
that you're going to need to be generating revenue if you were to eat
away at it as you consume that revenue over
the retirement years. And then you would be
thinking about a goal, an end goal to get to
that lump sum of money that you would need at
the retirement point. So in this case, we're going to start
off with the first of the two scenarios thinking about we're in our earnings years, we're going to try to
save as much as we can and think about what
if we were able to put away just say $5 thousand for the next 40 years
and get a return. We're going to estimate
an average return or an even return in this case, which is one of the limitations
of our present value, we're going to kind of estimate
a nice even returned of the 7% over that
entire time period. Note, of course,
you can get more complex with these
kind of scenarios. You could then increase in C, I'm going to put 5 thousand
in for the next ten years. And in the next ten years
I think I'm going to earn more money and I'll
put 10 thousand in, in the future and
so on and so forth. But to do that, you'd have to get a little
bit more complex than simply just an annuity, right? You'd have to then make
some adjustments because your payments into the retirement
plan would not be even. But you can use these tools for similar calculation
as that as well. So let's look at this.
We're going to say the investment each
year is gonna be 5 thousand that we're
going to put it and we're gonna say it's gonna
be for 40 years. We got 40 years to
save this depths, and then the rate
is going to be 7%. So we're going to say a rate
of returns seven per cent. So let's first do this with our running balance calculation, which you might think
that's a tedious thing to do given the fact we're
talking about 40 years here, but not hard to do with Excel. You can go out. You
can even do it on a monthly basis
if you needed to, because you could just simply copy and paste this thing out. So let's do that. So we're going to start
off at period one. Note that when we think about
an annuity calculation, we're typically not
starting at time period 0. We're going to start because
the annuity happens, you assume kind of at
the end of the period. And that's how the
calculation works. So if you have an
initial investment at this point in time and
then are adding to it, then you got to account for that basically initial
investment and then the annuity
component to it. So note we're starting
at one instead of 0. Then two, we're going to
select those two cells. And then I'm gonna
put my cursor on the autofill handle and
drag all the way down. Notice it gives me
that nice little number range that tells me where we are at all the way down to
40 periods and then let go. I'm going to center that
by going to the Home tab, the alignment and center it. There we have it. And then I'm gonna put the investment and
the outer column, and I'm going to have this
as the initial payments. The investment is the initial payment that we're going to have as we consider it
to be our annuity, which we're going to say
happens in year one. So we're gonna say this is
equal to the 5 thousand. And then I'm going to
have the investment just simply be the
same, 5 thousand. Now, I'm going to do this
fairly quickly because we've seen this calculation
in the past. So I'm going to copy it down and I'm going
to populate this assuming that it will be
copied down from here. Meaning any cells that need
to be absolute reference, ties are into an
absolute reference, those typically outside the
table from our dataset. We will do so as we go. So we're going to say
that there's gonna be an increase which will be equal to the 5 thousand. And then we're
gonna multiply that times the rate, which
is gonna be the 7. 7% is outside the table. So that's something
that I do not want to move down when I
copy the cell down. Therefore, I'm going
to make it absolute. I'm gonna do so by selecting
F4 on the keyboard and, or put a dollar sign
before the B and five, only a mixed
reference is needed, but an absolute reference
works and it's easier to think about the payment then is
always going to be the same. So I'm going to say
the payment equals. That 5 thousand this time
I'm going to make that an absolute reference by
selecting F4 on the keyboard, putting a dollar sign
before the B and the three, and then Enter. And then we've got the
initial investment, which is gonna be the 5
thousand plus the increase, which might be interests. It might be increased
in value if it's in stocks and whatnot
are index funds, different types of
investments that we have. But we're going to say
the increase in value is going up by the 350. So I'm going to
say plus the SUM, shift nine of these two, and then we're
entering another or adding another 5
thousand into it, we're saying each year. So then I'm going
to close that up. And there we have it. So now we've got the 5 thousand plus another 5
thousand that happened in year two plus the interest that is accumulating as we go. I'm going to select these
three cells and I'm just going to auto fill it
all the way down now. So I'm gonna put my
cursor on here now note, if we're not confident that
this was going to work, you might auto fill it
down simply one cell, double-check these
cells that they are doing what you expect them to, and then copy them the
rest of the way down. Selecting these three, putting our cursor
on the fill handle, dragging all the way down to 40 time periods down here
and there we have it. And so we're down here
at after 40 years, we're at that 998176. So almost at the million
there in the 40 years that just the 5 thousand per year. And we could see, we could
see how the increase in the interest is
happening here as we go. Fairly small amount
of increase with a gain on the revenue
that we're generating. As we go through here, you can see how much we put in, in terms of total payments, the sum of this column, we would be putting
in 5 thousand, that'd be 200 thousand that
we put in over 40 years. And how much we earned, which would be this column, which would be income from it. This would be the 798176 over and over those
40 year time period. So hopefully you can see the
running balance table really useful to get a better grasp
of what, what happened. Now if you were to ask them
when they are even work with a financial analysts to on
this or something like that, they probably wouldn't
graph it out like this, but would rather just do a future value of
annuity calculation. So let's do that now and note the contrast
between the two. You probably want to do both
of these things in practice, the annuity
calculation in Excel, and then show it to yourself
by actually calculating, calculating the payment
to confirm what is in your mind and then get a better visualization
of what is happening. So this is gonna be equal to
the future value shift nine. We're going to pick up the rate, which is going to be the seven
per cent over here, comma. And then the number of periods is going to be for T periods. And then comma, we do have a payment this
time because we're talking about an annuity instead of a present
value of one. In other words, we're
not just talking about 5 thousand and the
interests that will accrue on that or increase on at or be earned for it over 40 years, but having another 5
thousand that will be inputting every year for
the 40 year time period. So Enter and there
we got our 998175. Let's make that a positive number by double-clicking on it, you could put a negative
in front of the B here, or in front of the f, which I choose to do in front of the f. So there we have it. So again, this would be
the first thing that most people would probably do, or the simplest thing to do. But notice how much
more information, how much better
you get a grasp of it if you actually
graph it out here and then put the table together for it and you can determine how much your payments will be, how much the interest will be. You can look at the
yearly interest as well. You can take into consideration the tax impacts on different
types of savings accounts, whether you put it into
an IRA account or for one K or outside of the
IRA or Roth IRA and all that fun stuff that you can take a look at with
the savings account on a yearly basis and consider the tax impacts related
to just to note also, you might be thinking,
well, if that's 7%, that's gonna be my rate of, of revenue or gain
that I'm assuming. What about inflation? Because you might think, well, the purchasing power is
gonna go down over 40 years, around one to 3% as well. So when you think
about the actual purchasing power
you're going to need, you're also thinking
about where, where's that endpoint
going to be? You're going to need more
money, in other words, to retire 40 years from now, you would think than today. If the economy does, hopefully it goes well
and that there's gonna be some kind of inflation
that will happen. So when you play and how much money you're
going to need at the end. Is that going to need, is that
going to be enough money? In other words, in 40 years,
it might be enough money. The starting point, if you
look at it in 40 years, you're going to have
different purchasing power related to it. So you got to take into
consider Asian inflation. So let's do this a couple
of different ways. We'll do this with
the formula now, which is less
likely to be needed in when you go to a
financial planner, they're not going
to break out this, this future value
formula most likely, and putting it
together that way. But when you're in
a school setting, they might do that and
then we'll use the tables. So let's go ahead and
put our cursor on. Let's go to column C and drag over to column J
and hide those cells. Right-click on those
cells and hide them. And now we'll put
this formula into a table over here and do that and try to build
our table with it, which is good practice in Excel. So we have the future value
equals of an annuity. That's gonna be the P,
which is the payment, the 5 thousand times
one plus the rate, which is 7% to the n, which is the number of periods, or 40 minus one over
r, seven per cent. So you can type,
you can write that down and solve it algebraically. We're going to put
it into our table. The practice putting
things into a table, into a tax return
kind of format, into a financial
statement format. To do so, I want these
two primary components to be on the outer column. And then I would like
these other two primary numerator and denominator
to be an inner columns. And then this more
complex numerator, I might break out to
another inner column. So we've got the payment,
that's going to be easier, that'll be in the
outer column up top. The payment is going to
be equal to 5 thousand. Then I'm going to pull it into the inside of this thing
and I'm going to try to get to the numerator first because it's
gonna be more complex. So let's pick up the numerator. I'm going to indicate
a colon that this is gonna be pulled inside. And then I'm going to say
that this is going to be one. And then the R,
which is the rate, is going to be the 7% or
something right here. That's gonna be equal to the 7%. Let's percentiles that by
going to the home Tab Numbers, Group per cent ties it, font group underline it. Then we'll have a subtotals
sub TO tau sub tote, which will equal
the SUM shift up, arrow holding down,
shift up again, making that then a percent Home tab number percent times 107%. Then we're going to take that
to the number of periods, number of periods or n. And so that's gonna be right
here in our calculation. That's going to be 40 periods. 40 periods. And let's underline
that by going to the Home tab font
group and underline. That's gonna give us another,
let's call it a subtotal, subtotal, sub total
toe, toe, toe. And that's gonna be in
the outer column here. Actually, I'm not going
to bring that in the other column that's
in the inner column. This is going to be equal
to the 107 per cent shift, six carrots up one and Enter. So that's gonna give us our 15. Let's add some decimals, make it more specific
Home tab number, decimal lies in it. So 14.19744 and so on. So that brings us to this
whole piece, minus one here. So I'm just going
to say less one. And that'll give us
our whole numerator. So that'll give us
the numerate torr. Finally, that'll finish
up this calculation. So let's indent
this whole thing. Go into the home tab
Alignment indent, and then I'm going to
indent this again, Home tab Alignment,
indent again, let's underline this one. Home tab font group underline. Bring this to the outer column and this is going to be
equal to that 14.97. So on minus the one
gives us around 14. Let's add some decimals. Home tab number, destiny symbolized, Dustin
normalized it. And then we're going
to say this is gonna be the denominator. So that's the whole numerator. Now that this whole
thing is done, denominator is simply
going to be our or the 7, 7% percent percentiles in
that home tab numbers, percentiles, font
group underline. And then that's gonna give us, Let's call this a
sub tote, subtotal. And that's gonna be
in the outer column. Now that's this whole thing. We've now got this whole thing that's going to be
in the outer column, which will then
multiply times p. Notice we're only
doing calculations in one column at a time. In other words, I'm
not jumping from a calculation from one
column to the other. That's common practice in financial statement
type settings. So this is gonna
be that divided by the 7% then num
divided by the denom, adding decimals Home tab numbers destined to mobilize in it. And then underlying font
group and underline. And that'll finally gave
us the future value. Finally give us
the future value, which will be this times
this or the outer column. Now only doing things in
one column at a time, the 5 thousand
times that 199.63, whatever and so on. Let's add a couple
of decimals here by going into the home tab
number coupled decimals. So when 99817556, Let's do it one more time
this time with the tables, this time with the tables. So hopefully a school
doesn't make you do that. Algebra too much on it. And they might give
you the tables which is slightly nicer, which is just going to
take this 5 thousand and multiply it times the
amount from the table, which would be at
periods 40, rates seven. So we're looking seven
on the rate 40 all the way down at the bottom of
the table, way down here, 199.635199.635199.635199.635, adding some decimals, Home tab number group decimals. This is from the table. Let's go ahead and underline that by going to the Home tab, font group and underline. And that'll give us once again the future value of an annuity. Multiplying this
out, this is the 5 thousand times the 1.63599. Add a couple of decimals there, Home tab number group
coupled decimals. We're up to 998175, slightly different than the 9.5698175 due to the fact
that this number right here, which is the number that
is used to build table, is really more than three
to four digits out. So they rounded it on the table, resulting in a slightly
different number, which can be somewhat more distinct when you're talking
about larger numbers, but as often or when you're looking at retirement
type of accounts. So just notice that that
rounding difference could be larger as you deal with larger numbers depending
on the circumstances. Okay, Let's unhide and recap. So I'm gonna, I'm gonna
put my cursor on l, drag on all the way back to B and unhide those cells,
right-click and unhide. So there we have it. I should probably
run a spell check. Let's just did I
misspell anything enumerators spelled wrong? Okay. Got it. And then so now we've got this 5 thousand
all the way down, gives us that 199998176. So notice this
table very useful. Then we've got the future value. This is probably what someone
would give you if you talk to a financial advisor. And then it's really
useful to plug that into a table so you
can visualize it. You can get to that same
9.5698998175 with the formula. And you can get to a close
number with the use of the tables which you might
see in book problems, mainly in the school setting.
11. What if We Saved Our $5 a Day Coffee Habit: Personal finance practice
problem using Excel. What if we saved our
$5 a day coffee habit? Prepare to get financially fit by practicing personal finance. Now before we go into
this in much depth, I do want to point
out something that many people are
probably thinking. So we can address that first. Many people are
probably thinking, I know what would
happen if I cut my $5 a day coffee habit, I'd fall asleep at
work, I'd get fired. I wouldn't have any money then I'd have to spend all my time in the coffee shop because that's the only place I
get decent Wi-Fi. And if I didn't buy any coffee, then the baristas were all
get mad at me because I'm sitting there using
the Wi-Fi and not buying any coffee and so on. If not buying coffee,
in other words, would cause you a problem, then you don't have to do this. But the general idea would
be that if you can cut out a little bit of money on
a daily basis and save it. It could kinda go a long way. So here we are in
our Excel worksheet. We have the practice
tab on down below, and then the example tab, the example tab, in essence
being an answer key, we got the information
on the left-hand side. We're going to populate
that into the blue area. On the right-hand side. We're going to imagine we have
a cost per day of the $5. We're going to imagine
that we saved that $5 in some way, shape or form, possibly buy coffee,
possibly in some other area. So then we're going to say
that how much would that be on a yearly basis if we were
to add that up those days, a yearly basis, I'm going
to use that 360 day year, which is often done in finance because it kind of
evens out the months. Meaning it's nice to be able
to assume 30-day months. So it's all nice and even 12
times 30 would be the 360 as opposed to the more close to accurate number in
terms of actual days, which would be around 365. I'm going to take
then five times 360, that would be $1800 a year. And then let's assume
just on a yearly basis. And again, you could do
this on a daily basis, but let's say we take
that $5 and spend it on a yearly basis of the 1800 and put it into
a savings account. What would that do if we
could over ten years, if we're assuming
compounding yearly at eight per cent in
whatever we're investing in, whether that'd be stocks, that savings account or so on, in terms of our average
investment returns at the 8%. So this would be a future value of an annuity type
of calculation. Let's first do it by just doing a running balance
type of calculation, just listing out the number of years and assuming that we're depositing or making another
deposit yearly of the 1800s. Now this is an
annuity calculation. So we're not going
to start at 0. Usually we start at the
end of each period, which is going to
start at period one, period one, period
two, and so on. Let's copy that on down
with the auto-fill. I'm gonna do this a little
bit quicker because we have seen this in the past or similar problems just as a different kind of scenarios
to take a look at here. We're gonna go to
the Home tab up top alignment and center this. Now the first payment
is going to happen in year one and our
assumed annuity, and we're gonna do it
on a yearly basis. We're going to assume that 1800. Now, note that you
could do this. You could think about, well, I'll save that money on a weekly basis or a
monthly basis and so on. You can adjust your
calculations accordingly. We're going to keep to
the yearly basis here. We might do that in a
future presentation to look at the compounding
that could happen or the annuity that could happen if you're
putting more money in on a basis other than
basically a yearly basis, then we're gonna have the investment which
is going to be equal to the 1800s starting point, then the increase
that we're going to have from the investment, which could be from stocks, could be interested
in a savings account, and so on would be equal
to the 1800 times. We're going to pick up the 8%. I'm gonna make that an absolute reference because
we're outside the table. I want to copy this cell down. I'm going to do that by
selecting F4 on the keyboard, putting a dollar sign
before the B and the six, I'm going to select
tab this time, which will take me
right to the tab to the right instead of Enter, which will take me
to the tab below it. Then we're going to
pick up the payment which is gonna be that 1800. That once again is something
outside the table. I want to make it an
absolute reference selecting F4 on the keyboard dollar
sign before the B and four, I'm going to say tab now taken up to the
cell to the right. Then I'm going to say
equals the one above it, plus the SUM shift nine left arrow and then
holding down shift left, again, closing up the
brackets shifts and Enter. Now I'm going to select
those three cells and auto fill it down, putting our cursor on the fill
handle, dragging it down. And we can see the increase resulting that we'd
be saving on a, on a earning on a yearly basis, we would be having 26,076 the payments that
we put in place. You can select this column
and see the sum calculation, 18 thousand over the ten years. And the increased
meaning the earnings and interest or whatever
format we have, 8,076. Let's do that same thing
with an annuity calculation. Now, let's hide some cells
from C onto G. Let's go from Right-click and
hide those cells. We're gonna do this with
an annuity calculation. Once again, I'm gonna
do this a little bit faster since we've
done this a few times, I'm going to say negative
this time instead of equals, which is a little bit faster. And we'll flip the sign so that we do not have
to basically put, go back in and put
a negative number. It will then result in
a positive end result. Notice I can still type
in future value here and it still gives us
our functions down here, just like if I typed equals. So if you want to
flip the sign easily, instead of putting a negative, instead of putting equals, you could just start with
negative and then type your function like you
normally would shift nine. The rate is going to be equal to this eight per cent comma. The number of periods
is going to be ten in this case comma, and then the payment is going to be because it is an annuity, we will be using the payment
that 1800 and enter. There. We got the 2675. Again with the $0.81. We could do that same thing
with the calculations for a table and the calculations for the mathematical formulas. Two ways you
probably wouldn't be doing this so much in practice, but can do oftentimes
for test questions. So we're gonna put our
cursor on H, drag to j. Let go, right-click that
selected area and hide. We're gonna do this formula now, future value of an annuity, which is the payment,
which is gonna be the 1800 times one plus r, which is going to be the 8%
to the number of periods, which is ten, and then
minus one divided by R, 8%. Practicing putting this
into a table format, a format you might see
in a tax return or similar to a financial
statement format. We're gonna put the payment
up top outer column 1008. Then we're going to
have the numerator. I'm just going to call
this the numerator, which is gonna be
this whole thing, which I'm gonna put in the
inner column or inside and indicate that with
the colon up top. I'm going to bring
that inside here. This is going to be equal to, let's say one right here, that I'm picking up the rate, the rate which is going to be equal to the eight per cent, making that 8% by going to the Home tab number
per cent ties in it, underlining it, Home tab
font, group and underline. That's gonna give us a subtotal. We're going to
call it sub total. Summing this up using the
trust, The SUM function, SUM shift up, arrow
holding down, shift up. Again. Let's make this a
percent by going to the Home tab numbers and
percentiles it 108%. We're gonna take that to n Now, which is gonna be the
number of periods. Here we odds, and
that'll be n periods, which is gonna be
ten equal to ten. Underlining that
we're gonna go to the Home tab font
group and underlying, we don't really need
the decimals here. Removing the decimals, then
we'll have another subtotal. So this is going
to be a subtotal. And we're going to
take this as equal to the 108 per cent shift six or
carrot to the ten periods. That's going to give us two, but we're going to add
some decimals going to the Home tab number group
desk, normalizing it. And then that's going to be
this whole piece right here. Then we're subtracting
one from it. So I'm going to
just say less one. Underlining that by going to the Home tab font,
group and underline. And let's give us
That's going to be the numerator, torr. Torr. Let's put that in
the outer column, and this is gonna be
equal to the 2.15. So on minus one. Let's make that eight per
cent or add decimals, I should say Home tab number, group desks and normalized. So there we have that. And then we got the denominator. The denominator. So we've got this
whole thing here. Now we're going to
take the denominator, which is simply R, put
that in the same column, that's going to be 8% the rate
making that a percent Home tab number group per cent ties and then font group
and underline. And that'll give
us, Let's call this another subtotals, sub total. Putting that in
the outer column, this being equal to the numerator divided
by the denominator, making that then a desk animal eyes number
adding decimals, in other words, Home tab number, group, desk normalized, then
font group and underline. And that'll finally get us to the future value of the annuity. Future value of the annuity. Now, multiplying these two
components, the outer column, that being the 1800, times the 14.48 and so on. We get about 2676. Let's add some decimals
Home tab number group, a couple of decimals. Let's do some indentations here, selecting these items and indent them home tab
Alignment, indent. And then we'll take the
numerator and dent that again. We could do some spellcheck, see if I misspelled anything. Yeah, of course. Of course you did
misspelled stuff. Okay, so there we have
it now let's do it with the table one more time
with the table time. And this is gonna be a payment. And the payment is
simply going to be that 1800 picking them
out from the table, making sure we got
the proper table. This is the future value
of an annuity table. And we're looking 810810. Here's the eight. Here's the
1014.48714.48714.48714.487. Add a couple of decimals, Home tab number coupled decimals underline it
font group underline. And there's our FV
future value annuity. Multiplying that out equal
the 1800s, that 14.487. And so we're at the 2677, 60 close to the twenty six, seventy five, eighty one. Not exact due to rounding. This being the actual
number that would be on the table if they took it out more than three
to four digits, this being where it is at. If only taken out
three to four digits, resulting in a slightly
different number between the table and
our other calculations. Let's go ahead and unhide
ourselves by going to the be to L column. Let go right-click unhide. We're going to say if
we save that money, we would be totally tired and our whole life
would fall apart. But we would have we would
be able to save $26,076. All the baristas would hate us, give us mean looks in the coffee shop because
we never buy anything. But we would save $26,076
or an urn that over time. If we saved it, then we'd
have the future value of the annuity also twenty-six,
seventy-five eighty one. If we calculate it
with our function, we calculated it this way. Twenty-six seventy-five
eighty one with a formula and then slightly different twenty-six
seventy six, sixty. If we use the tables.
12. Option to Receive Money Today vs a Series of Payments: Personal finance practice
problem using Excel option to receive money today versus a series of payments
in the future, prepare to get financially fit by practicing personal finance. We are in our Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tap the example tab in
essence being an answer key, we have the information
on the left-hand side. I'm going to populate
that into the blue area. On the right-hand side, we have our general
type of scenario. The general circumstance being that we have a
lump-sum that we can either receive now or received a series of
payments in the future. This type of problem often represents something like a
lottery type of situation. So if we won the lottery, you get the question as to whether you want to
get the money upfront now or if you want
to get them in a series of payments
in the future. This could also apply to
other scenarios such as like winning a lawsuit settlement
or something like that, or insurance settlement,
you could possibly have a similar option of either
receiving an upfront some, or a series of payments. So for example,
here's our situation. We have the option to receive
45 thousand today for whatever reason
that might be might be some type of settlement,
might be the lottery. We want some prize or
something like that. Or we can get $7 thousand
payments for nine years, which would be better to
7 thousand payments for nine years or the
$45 thousand today? Well, the answer will depend on our discount rate that
we will be using. So for example, if I just
look at the dollar amount, of course, comparing the two, the 7 thousand here, I'm just going to equal to
7 thousand times nine would mean that over nine years
we would get 63 thousand. Which would of course indicate
that this one would be better because we're gonna get more money than
the 45 thousand. But of course we're going to
get that over nine years. And the option, the other option means that if I had the money today than I might be able to
do something with it today. And the common response,
oftentimes it's well, I don't maybe I don't need
the 45 thousand right now. So I'm okay with getting at 7 thousand a year or
something like that. But still, even if you've got the money today and
you didn't need it, you could put the money to work and have it earning
a return on it. So there's at least two factors
that are involved here. One, time value of money
will typically go down. So if I get 7 thousand
a year later, the purchasing power of
that 7 thousand will typically be less than
if I got it today. But above and beyond that, if we got it today, we could put it to work
with something today, either spending it
on what we want or by investing it and
getting a return on it. Whatever that return is, the thing we're losing. That's the opportunity cost of us choosing the other option. So that'll be more than just generally inflation if we think we can get a return
higher than inflation. In other words, if
I thought I can get that 45 thousand today, invest it in some way or use it in some way
where I'm getting a benefit that I believe is
worth a 7% return on it, then that, then that's the return will have to
take into consideration. So the biggest problem
with these types of calculations is where do
you get that 7% return? It is not simply
the interest rate, because the interest
rate in the US might be around one to 3% if the Fed or the government shoots
properly for what they want. But it's also the opportunity costs that you're
losing for what you think you could have
gotten with that 45 thousand if you had it today? Again, either through the
pleasure of simply using it if you needed it or
if you don't need it, then where you could have
invested at what return are you losing by not
having it upfront? And that's gonna be
the discount rate that will have to use here. If we, if we assume
that then to be the 7%, we'll do our calculations. So if we get a series, obviously if we get
the lump-sum payment that happens at time period 0, we get the money today, we do whatever we want with it. We might invest it and get some return on it at
that point in time. If, on the other
hand, we're gonna get a series of payments
of 7 thousand. Then we're going to discount it. We're going to discount
that series of payment using the present value
calculation to try to get a number that is equivalent to this time period 0 numbers. So we can do our comparison. Let's start that
off with a formula. Excel formula equals
the present value is going to bring it back
to the present Shift, Nine, left, left, left, left. We're going to pick up the rate. So we have the right
here and then comma, we're then gonna go left, left, left number of periods, which is gonna be nine comma. And this will be a payment
instead of skipping the payment to go
to the future value because this is an annuity. We're dealing with series of payments, so
we're gonna go left, left down to the 7
thousand and Enter. I'm going to make that
a positive number by double-clicking on it and
then flipping the sign. So I'm gonna put a
negative in front of the p. You could put a
negative somewhere else, banker put it in front
of the p in my case, and that's gonna be the 45605. So that's pretty close
to what we had before. So if we got the
lump-sum payment where we're at the 45 thousand. This one is slightly
more so the annuity, it looks like it's
gonna be slightly more even if we present value it at the 7%. So we're comparing, of course, 0 period $0 to getting the money today to the period
$0 equivalent, assuming the discount
rate at the 7%. Let's do the same calculation with our mathematical formula. Before we do, we're going
to hide some cells. I'm going to put my
cursor on column C, drag over to column E, let go, right-click, and let's
hide some of those cells. So we're gonna be working
here on the table. I'll make this a
little bit larger so we can see our information. Okay? So now we're going to
do this calculation will do this fairly quickly because
we've seen it in the past. I want to jump to the running
balance calculation next, which I think is a
useful thing to look at. So if you want to skip
forward to that one, you can't hear if you don't
wanna do this calculation, but I think it's worthwhile to look at the running balance. So it's going to be p
equals the payment. The payment is gonna be the
7 thousand times one minus the one over one
plus r 7% to the n, nine periods over
r seven per cent. I'm gonna plug that
into our table format, putting these two
primary components and the outer column and any sub calculations inside
in the inner columns. So we're going to start
off with the payment and the outer column here, and this is gonna
be the 7 thousand, so this will be the 7 thousand. And then I'm going to
take the numerator, some sub categorizations, this whole thing
on the numerator. And then I'm going to
do another subcategory, which is simply going
to be this numerator or the one on the full numerator I'm going to put on the outside, this one is solo one. And then I'm gonna put this
calculation in the inside. So I'm looking up
the other numerator, which is this one on top, which I'm gonna
call numerator two, which I know is not the
most descriptive name. Enumerate tore too. And that's gonna be then one, this one right there, one. And then I'm gonna put that
over the denominator here, the one plus r to the n. So I'm going to say the
one plus r shift to the n, going to put a colon indicating
that this is gonna be a sub counter calculation
of that inside here one. And then I'm going to say
the rate is going to be r or seven per cent per cent. To find that by going to
the Home tab number group, making that 8% font group
and underlining it. Then that's gonna
give us a subtotal, which I'm gonna call sub TO Tau. Use the trustee some
function equals the SUM shift nine up
arrow holding down, shift up again and enter, making that then a percent
Home tab numbers percent define it 107 per cent. Taking that to the periods
and periods which is n, that's gonna be nine years. So that equals then
the nine years. Let's underline that by
going to the Home tab, font group and underline. Then that's gonna give
us our whole thing, which is one plus r to the n. And let's get
rid of the colon though, removing the colon,
putting this into the outer column because we had the colon indicating
a subcategory. Now go into the outer column. This equals left up, up, shift six carrot, left
up to the power of nine. Enter. We're going to add some
decimals to give us a bit more detail there by
going to the Home tab number, group, deaths in the Molas,
did destiny symbolized? Then that's not a real
word, but remember, but it's fun to say,
there we have it. So now we've got this, this whole thing, bottom part, and now we can divide
these two out. I'm going to call
that then a subtotal. Subtotal. Put that then in
the outer column. This is going to be,
I'm only working one column at a time. So now I've got this
one right there divided by this desk, the normalized number,
adding some decimals there, Home tab number group. Yes, in normalized. Then go to the font
group and underline. Then we can say now we've, we've got wherein
this outer thing. So now we're gonna do this
as B, the whole numerator. Now, put this in
as the numerator. And I'm going to keep
this in the same column, even though it's, keep
it in the same column, this is going to
be equal to one, This one way up top minus
this desk normalized number, which also needs to be desk
normalized Home tab number, deaths in them allies. And then we're
going to take that divided by the denominator. So we'll say denominate torr, which is the rate. And that's going to be
equal to the 7, 7% percent. Making that up per
cent by going to the Home tab numbers
group per cent to find it font group and
underlining it. And then that's gonna
give us a subtotal, again sub TO towel
in the outer column, which is going to then be
that's going to be equal to the num array ptr divided by that denom and adding
some decimals there, Home tab number group, yes and no lies. And that'll get us finally to the present value calculation
down below present value. Which is gonna be
these two components multiplied together
the thing way up top, which was the seventh thousand
times this 6.51 and so on. Let's add just a
couple of pennies. Home tab number group couple of pennies, do some formatting. Let's underline this one, home tab font underlying. Let's add some indentations to this whole thing right here. Indentations to
this whole thing. I'm going to say Home
tab Alignment, indent. And then let's indent
this thing again. Let's do another
indentation here, Home tab Alignment
and dent that again. And let's indent
this one more time. Uno vase mosque. Poor or five or that was
my attempted Spanish. Sorry about that.
Indicates here we have it. So now we're going to
then lets unhide some, let's hide some columns. And let's do this
again with the, with the running balance. So I'm gonna put my
cursor on column F, left-click and drag over to k. Let go, right-click
the selected area and hide those columns. Note I've made an
adjustment here from the table to
another kind of concept that might make this a little bit more
clear of a decision. Note when we have
a decision between these two items,
something like this, what we will typically do with bring things back
to the present, present value them
so we can compare them both in present
value terms. It might make sense to or
help to solidify this by thinking about them in
future value terms as well. In other words, if I had
this 45 thousand upfront, the assumption of this
discount rate is that I can get value of that 45
thousand at a 7% return. So I could think
about, okay, where, where would I be in nine
years if I got a value, some kind of return of a
seven per cent on that, and compare that then to the future value of
the annuity payments, assuming I can get
a 7% return as we basically get the money for
nine years in an annuity. So let's do that and I'll
just do this one with basically the Excel
functions here. So I'm gonna say
this is gonna be the future value of a lump-sum. So I'm going to say this equals the future value shift nine. I'm looking at the
rate which is going to be that 7% comma, the number of periods
is going to be nine. And then I'm going
to have two commas because I'm not going
to put a payment here. But look at the present
value of the option of getting the money
upfront, the 45 thousand. So we'll start with a
45 thousand and Enter. And that'll give us
the AD2, 731 about. Now let's think about
the future value. If I was to get 7 thousand
for nine years and be able to invest that 7
thousand when I get them each time period at the 7%, where would we be in
terms of future dollars? We would be at the negative
future value shift nine rate will be 7%. Comma, number of periods, I'm gonna say is nine. And then comma. Now we will use the
payment because this is an annuity calculation. Let's take the 7 thousand and
enter. So there we have it. So you can see where a
difference between the two. Let's see what that
difference is. As far as future dollars, this would be equal to AD2, 731 minus the 83846. That's a difference of 100115 in terms of future
value dollars. So we brought these both out nine years into
the future and we have a difference in
future doubt value dollars of the 1015. Let's now think about bringing
that future value amount, that future value
difference back to the present by basically discounting it back to present value, present value of
one calculation, which would be negative
present value shift nine. The rate would be the 7% comma, number of periods would be nine. And then comma, comma
because it's not a payment, we're gonna, we're
gonna present value, this future value amount
Back to the current point, and that would
give us these 607. Now note, if we unhide
some cells here, I'm going to unhide from m, from B to M. Putting my cursor, I will be selecting over two m. Let go, right-click and unhide. I think I did the
wrong thing I hit. I'm gonna go from a to N, right-click and unhide.
I don't want to hide it. I want to unhide it. So notice when we did the present value here,
we had a difference. Let's put a difference
column here. And I know this is
jumping around, but I felt that this
might be more beneficial. So we've got the
45607 minus the 45, there's our 67 seven, right? So when we present valued it, we had a difference between the two options of
$607 are pretty close when we future value it and think about it
in future value terms, you have a difference of 100115 in future value dollars
way out into the future, and then we can
present value that. And again, you get
down to the 607. So you can kinda think
about it both ways. The traditional way to
look at it, of course, is to try to take
whatever's in the future, bring it back to
a time period 0. But notice the
point is of course, that you're trying
to measure things as of apples to apples, they say or the same
thing to the same thing. So if you put both things out in the future, you can do that too. But again, if you
want to see it in terms of current dollars, you would then have to discount
it back to the present. Okay, Let's do the same
thing with the tables here. During the tables will
pick up the table and that's going to be
equal to the 7 thousand. I'll just pick it up right here. Pick up the amount
from the table, which is making sure that
we have the proper table, which is going to be the
present value of an annuity. We're back to the
present value thing. Present value of
an annuity table. We're looking 7%, 9 years, 7979, which is going to be
these 6.51526.5152, 6.5152, adding decimals by going to the Home
tab number group. You decimals there. And then that's gonna
be our present value of an annuity at T equal to the seventh thousand times the 6.5152 gives us about the 45606. So let's just recap
what we've done here. The two decisions going all
the way back to the left. We can either get the
45 thousand upfront or the 7 thousand over a
series of nine payments. If we got the 7 thousand over
a series of nine payments, it looks better at first
glance, of course, because that would be $63
thousand versus 45 thousand, but it's over nine years. If we were to
discount that series of payments were at the 45607, It's still better, but
only slightly than the 45 thousand by
the 607 difference. We then present valued
using the formula to get that 45607 about again. We then compared
it and said, well, what if we future
valued the two options? And we found that we got the difference between
the two options in future value terms nine
years from now, 100115. And if we present value that, we get that 607 different again. And then we did it
with the tables. And we got this 45606 again, let's go ahead and put an
underline under that one.
13. Loan Payment Calculation & Amortization Table: Personal finance
practice problem using Excel loan payment calculation
and amortization table, prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along
now that we're down here in the practice have as
opposed to the example tab. The example tab in essence being an answer key information on the left-hand side going
to populate that into the blue area on the
right hand side, looking at a loan
situation where we have an imagination
of our borrowing, the 11 thousand, the
interest is going to be 5%. Now, obviously, if
we are borrowing, interest is in essence, you can think about
it as the rent on the purchasing
power of the money. So we're borrowing money. It's similar to as
if we were using basically a place to live or for using
basically a place to work and renting that place
where borrowing the use of it and have to pay
basically rent on the use of it, interests. You can basically think of as the same thing we're borrowing
the purchasing power, have to pay rent for
that purchasing power. That's going to be called
basically interest. We're going to repay
in years, seven years. So we're gonna be making
installment payments will be paying yearly. And usually when
you're looking at a fixed kind of setup for
a repayment of a loan, which is quite common for a personal kind of
financing options. Although note, you could have different financing
options when you look at basically like
business financing options. But most of the
most common things we think about on the
personal side of things, we have a fixed set of
payments that we repay. Oftentimes we don't repay
yearly, we repay monthly. We will take a look at
monthly repayments, but that's a little bit more of a twist in our calculations. So we'll take a look at that
in a following presentation. We'll start off here
with yearly repayments. This would be applicable if
you're thinking about like a home loan or
something like that, which is often paid
off in installments, once again, monthly usually. But similar concept. Or if you're talking
about any kind of financing like a car or
something like that. Now first, we're gonna be thinking about the
payment option, which is often something
that you would be thinking about
if you're the loan, if you're the one that's
granting the loan. But clearly, if you're if
you're kind of budgeting yourself and you're
trying to think about how much money you
would want to borrow, then you would want to do a
calculation such as this. So think about what the
payments would be if you could get borrowing at
certain terms and whatnot. So that's gonna be the
kind of concept with it. Once you know what that is, then it's useful to make an amortization table to list out what the actual
payments will look like. So that's gonna be,
that's gonna be the idea. Now, you have this information. We could use the
payment calculation, which is a function in Excel, but it's kind of,
it's related to, once again, the present
value calculations. So oftentimes you
might first the most comfortable with the
present value calculations. And you might say, how about if I'm going to back
into this payment situation? Is there some way that
I can use basically the present value
calculation to do so. So let's, what we might start doing then is to take our data, start plugging it into the present value calculation
and see if we can use that with the help and use of the Goal Seek and then get
a better idea possibly, if there's another function
related to which there is, which is the payment
function here as we go, we might say, okay, let me see if I
could start plugging this into like a present value. Shifts nine, we're going to say the rate would be this 5%. So we're going to pick up the
five per cent and B2 comma, the number of periods
would be seven. So we know that we
know the number of periods would be seven, the payment amount comma then
we have the payment amount. And we should have
a payment amount because this is basically going to be a series
of payments kind of situation and that's
what we don't have. So if I look at
the present value, I'd say, okay, I
don't have that. I'm going to put that in a, in a cell down here and say
That's gonna be my unknown. And then the present value, the end result of this
thing we actually know should be basically
the 11 thousand, that should be the
starting point. So if I say Enter here, we can kinda back in
and use our Goal Seek. And we can also say, okay, I can either use Goal Seek or I can see that that payment
thing right there. The PMT is what I'm missing. Maybe there's an Excel
function which is called PMT, and we can do that directly. But considering I know the
present value more clearly, I'm going to use it first and use the Goal
Seek to kind of back into what I need and then we'll verify it with a
payment calculations. So I'm gonna, I'm gonna
type in a payment of 1 thousand down here
just to test it out. And I know the end result
should be 11 thousand now I would like the result
to be a positive number. So I'm going to
double-click on it again. I'm gonna put a
negative in front of the P to flip the sign. And then I can start
to adjust this. I can say, well, I know what the end result needs to
be that 11 thousand. If I make this like 2 thousand
or something like that, I'm getting closer
to the 11 thousand. I can ask Excel to do that for us using the
Goal Seek feature, which would be in
the Data tab up top. And the what if in
the forecast group, What If Analysis Goal Seek. Let us seek the
goal we want to set then this cell up top to be 11 thousand by changing then this data input cell
right here we can say, OK. And there we have
it, the 19011901. So in this instance then we
would have to make payments, repayments if we're paying
them on a yearly basis of 100901 for the
borrowing of the loan. Now we could also think about
that and say, okay, well, I can get there
more quickly with just a payment to
calculation down here. Let's use the trustee
payment calculation. This is equal to the PMT
payment shifts nine. The rate is going
to be over here at the 11% comma number of periods then is going to be the seven periods and then
comma the present value. That's our starting point. That's, that's gonna
be our loan amount. So present value is gonna
be the loan amount, that's the money
we're getting now and enter and there we have it. The 100901. I'm going to flip the
sign of it again, making it a positive,
double-clicking on it. You can do so by putting a negative in front
of the payment, which is probably more proper, I like to just put it
in front of the p, flipping the whole thing, multiplying by negative
one in essence. So now that we have that, we can then do our
calculation with our loan, with our loan over here and do basically an amortization
type of table. This is really
useful to be able to do and this will give you once again a better understanding. I'm going to make these
cells a little smaller here so we can keep all
this stuff together. A better understanding of the
pictorial picture of what you're basically doing and the interest in the
loan balance as we go. It can also help you to record the payments accounting system. If you're trying to track what's your current
loan balance is, what your interest is. So you can deduct
the interest for taxes and all that
kind of stuff. So let's go ahead and say
we got, we got year 01. I'm going to select
those two cells. We're going to put our cursor
on the fill handle and auto fill that on
down, auto-fill. Then let's go to the Home tab. Let's go to the alignment for some reason it's
shaded out here. I want to center that. There we go, center it. Then we're going to say that
we have our starting point, which is the loan balance, which I'm going to put at period 0 all the way in column K, which is going to be equal to the 11 thousand,
that's our loan. And we're going to
think about, well, what if we had
payments on that with the 9% interests and we're
going to make payments on it. This is a common
kind of format to set up an amortization
table you might want to practice if you're doing this in a school setting
or something like that. Or if you are calculating loans
for a home or purchasing, purchasing equipment or a car, you might want to set up a table like this and just
practice setting up the columns because that
can be a little bit tricky once you know
how to set them up. It's fairly easy to do this. And again, in Excel, even
if you're doing a loan with 30 year payments
and whatnot, even if you're
doing it by month, 30-year payments and you
gotta go down to 360 cells. That's okay. You
can copy it down. You can figure out
what the yearly interest rate would
be and whatnot. That's why
spreadsheets are nice. Spreadsheets are nice. So then we're going to say to the payment
that we're going to make each year is going to be equal to the amount was
pulled it from here. We already calculated
the payment. So there's the payment. Then we know what the
interest is going to be. The interest is going
to be the 11 thousand balance times the 5%. That's the rent that we're
paying on the borrowed money. So this is gonna be equal to the 11 thousand K3 times left, left, left, left, left, up to the 5% Enter. So that means that we're gonna
be paying the 1901 about. There might be pennies involved
here, we've rounded it. The interests related
to it is 550. So that means of the 100901550 is like go
into rent, it's gone. We're not getting any decrease in the loan balance from it. The difference
between the two is the decrease in the
principle that we will have. So we're going to say
the loan decreases the amount we pay minus the
rent on it, the interests. And so that 1351 about is what the loan balance
actually goes down by. So this is going to be equal to the 11 thousand minus that 1351. So now the loan balance
is going down to here. So if you were to record this in an accounting ledger
or something, decrease cash or the 100901
interests would be like rent, it would be an expense, and then the loan would
decrease by 1351, there would be three
accounts affected. In essence, bringing your balanced loan
balance down to nine, 1649 and record the interest
expense at the 55050, which would bring
down your net income. Okay, So let's do it again. The payment would then
be once again, 100901. Now, in a future presentation, we'll do this with
monthly payments, which will be a bit
more complicated because we'll have to deal
with the added periods. So we will do that in
a future presentation. It's not too much
more complication. Once you get this down, this is gonna be equal to
the 9649 times the 5%. Notice that the interest will go down because that's how
the loan was set up. So most loans are actually
set up in this format. So you can have nice
even payments that's easy for individuals and
companies to budget. But the sacrifice on that is the fact that you've
got this funny business happening between
the interests and the decrease in the
loan balance as it, as it goes down has a different amount
each time due to this. So the payments the same, but now the interest
is different. So now I got to take the
payment minus the interest. That means the decrease in the loan balance
is now different. So the interest will
always be going down because we borrowing less
money at this point in time. So we're paying less
rent on that money, and that means we're
paying the same amount. So that means that we actually
have a bigger decrease in the principle as the loan
continues on into the future. So this will be equal to
the 9649 minus the 1419. Let's do it a couple more
times and then we'll use our auto-fill feature
to copy it down. This equals the 1901, this equals the eight
to 30 times the rate of the five per cent. And then we have the difference. The 1901 payment
minus the interest, which is now at 412, gives us the decrease in the
loan balance of the 1489. That means the prior
loan balance of the 8230 minus the 1489 gives us the new loan balance that we
still have outstanding is at the 67 for one about. So we're going to pay once
again that 1901 and year four. Now the interest is going to be these 6741 times the
rate, which is 5%. And so we paid the
same amount 1901, but the rent or interest
has gone down 337, meaning the decrease
in the loan goes up. And our prior loan balance
was the 6741 minus the 1564 new loan balance, 5177. Let's do it one more
time and then we'll go back up and do it the easy way. Instead of this way I'm going
to hit this one then say tab instead of enter.
And then equals. That takes us to the
cell to the right, equals the prior balance
times the five per cent tab. And then this equals
the amount we paid minus the interest tab. And this equals
the one above it, the 5177 minus 1642. And that gives us the new
loan balance of the 3535. Now, before we end
this thing off, because we should be at 0 at the end and we would get there. But we're going to start over the suspense just to
maintain the suspense. And then we're going
to do it again, this time using
autofill to make it, don't do it easy,
do it the easy way. So I'm gonna delete
this whole thing. No, all that work was wasted. Okay, we'll do it
again. It's okay. Okay, so we're gonna say this is going to equal the payment
which is over here. Notice that from somewhere
outside the table, when I copy it down, I don't want that
cell to move down. So I'm going to say
F4 on the keyboard, dollar sign before
the E and the five, you only need $1 sign or a mixed reference,
but absolute works. Then we've got the
interest calculation, which is going to be equal to the 11 thousand times the rate. Note that the rate is
outside the table, which once again means
that I don't want it to move down one
when I copy it down. So I'm gonna make that
an absolute reference, hitting the F4 on the keyboard. Or you can put a dollar sign
before the B and the two, you only need a mixed
reference again, but absolute is easier
to think about. Then we can subtract
these two out. This is going to be equal
to the 1901 minus 255. Oh, those are both within our
table and I do want them to copy down relatively when it moved down properly
like they normally do. So I don't need to
do anything to them. Then this is gonna be
equal to the one above it minus the one to the left. And I want those
both to move down relative nothing is
outside the table there, so that one should
do as we want it to. So let's go ahead and then select these and
auto fill it down, grabbing fill handle,
dragging it down. If you do this properly, the bottom-line
number should be 0. That's your indication
that you've, that you've done this correctly. This can help you to actually
record your payments, breaking out the proper amount of interest in principle and double-check what's your
principal balance will be as, as well as give you help in terms of what your
interests payments will be. Interests is gonna be
something that's going to have an impact on your
income statement. And you could have tax
impacts on that because it'll typically be deductible
portion of the payment. Alright, now, let's do this one more time with
a table over here. You might say, how can
I do this with a table? Because the tables are
usually used to give us basically the the present
value calculation. So now I'm going to
use a present value of an annuity calculation to back in to a number on the table, which is something you probably
wouldn't need to do in practice because
you do it in Excel. But some nefarious teacher or something school
might make you use the tables in this odd way. And so we can say we can
do it, It's not hard. We just do our same table thing. We're going to say payment. You got the payment than
the amount from the table. And then the present
value of the annuity. This is how we usually
use the tables. What we're gonna do is now we know what the end result is. So I'm not going to
rework the algebra. I'm going to say,
Well, the end result is gonna be that 11 thousand. And then I'm going to
get the amount from the table and then I can back
into the payment from it. So we're just gonna
that's why it's yellow. That's why I made
it yellow because we're going to back
into the payment. So I'm going to say the
amount from the table, we gotta make sure we
get the right table. This is an annuity
table, present value, same thing we did up top
present value of the annuity. So we're going to use a percent
and the number of years. So five per cent and
seven, here's the five. There's the
75.78645.728645.78645.7864. And then we can back into this. So if this times
this equals that, I should be able
to take then this, the 11 thousand divided by that. And obviously you can write it down and work it
out algebraically. You can double-check it and say, did I do it right? If I take this times this, I should get 11 thousand. I did do it right. Okay, so there's that,
so we can do that. We can use those
tables and again, be aware that the tables can be used in such nefarious ways. If for test purposes and
then know how to do it. The easy way for actual practice when you're
figuring this stuff out.
14. Monthly Loan Payment Calculation & Amortization Table: Personal finance
practice problem using Excel monthly loan
payment calculation and amortization table. Prepare to get financially fit by practicing personal finance. And we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down here in the practice tab as opposed to the example tap the example
tab in essence being an answer key information on the left-hand side
and populate that into the blue area on the right-hand side looking
at a loan scenario, once again, similar a
prior presentation, but this time we're looking at monthly payments as opposed
to a yearly payments, making it a little bit more complex to do our calculations. So we're going to say that
we're gonna be borrowing the 11 thousand
for the borrowing, the interest rate this
time is going to be 12%. And we're going to say
that we pay repaid in monthly payments
for three years. So in other words, we're
gonna be paying it back for three years, but we're gonna be
paying monthly, as is often the case for many
kind of loan situations, like a mortgage or loan
for financing a car or something like that as it is typically going to be set up. Now note, as we look at
this payments calculation, if you were to get a loan for financing the car and whatnot, normally the person
that's calculating the loan will just give you
the payment information. You would like to be
able to calculate it yourself so that you can go into a situation and practice
different kinds of payments and interest
rates settings to see what would happen and also get a better determination
through the creation of an amortization table
of the payments and interest in what the relationship
will be to the loan. So let's calculate this out. We got our information,
we're going to calculate the payment then. Now first, you might first
be most familiar with that present value calculation as opposed to the
payment formula, there is a payment function, in other words in Excel. But when you're first
looking at this, you might say, look, this looks like a
present value of an annuity kind of thing because the payments
are all the same. Let's try with the
present value, see what the unknown is, and possibly use our goal, seek to figure it
out and then see using the present value
function whether or not there's another function
that we could then use called the
payment function to then rework the equation and
solve using that function. So in other words, we might
first start off and say, let's, I know this is a
present value kind of things. So let's go Present
Value Shift Nine and say that we have a rate. The rate is gonna
be the 12 per cent. Now, note this is where
it's confusing that 12% is a yearly rate. And normally when you're
talking to people, they will quote a yearly rate, because the yearly
rate will be somewhere between 1, 100% generally. But we're gonna be
paying monthly. And therefore we got
to have the rate that's going to be
equal to the payment. So I need to take the yearly
rate and divide it by, divide it by 12 in this case. So that's gonna be the
kinda twist involved here. Note that no one really
quotes the monthly rate, which in this case would
just be 1% per month. Because although 1% is
fairly easy to say, if it was 1.05432 or whatever, something like that,
then obviously that becomes much more difficult
to to be dealing with them. The yearly rate, which would be just simply 12 years
or the convention. And then you have to basically make the adjustment
to whatever you need to adjust it to use
in your calculations. Then I'm going to say comma. We have the number of periods. Now the periods were
given in years. Once again, it's going to
be paid off in three years. But just like if you had a 30-year mortgage or
something like that, but you know, you're gonna
be paying it off monthly. So you're going to take
that three years and times 12 because there's
12 months in a year. So we'll take the
three years times 12. And then we're going to say
comma and the payment amount. That's what we don't know. That's what we don't know. I can do two things. I could say, well, I
think the end result here should actually be
the 11 thousand, the amount we're borrowing. That's the present value. I can then use goal seek
to figure out the payment. Or I can go to
another function and see if Excel has a function
called Equals PMT, which it does, which is
the payment function. So we're gonna start off
here pointing to this cell and try to use Goal Seek
to back into this first, because we might
first understand the present value
calculation best. And so there we have it and then we can guess at a number. I could say, well,
what if this was 500? We'd get a result of 1545. We want a result of 11 thousand. That's what should be
in the end result. I would like it to be a
positive number, however. So what I'm gonna do is
double-click on this 11 thousand. I'm gonna put a negative
in front of the p, which will basically
take the entire thing multiplied times negative one, flipping the sign to
that 15,054 positive, then I can adjust this
number down here to like 400 and so on until I get
it to what it should be at, which is that 11 thousand. We can then ask Goal
Seek to do that for us by going to
the Data tab up top, go into the forecast group, the What If Analysis
and say Goal Seek. We're going to seek
the goal and we want to set then this cell to be 11 thousand hardcoding
that in other words, typing it in there. Then we want to do that
by changing this cell. So we're asking Excel to make that cell whatever
it needs to be the payment so that that cell
up top gets to the answer. We know what should be,
which is 11 thousand. There we have it
where at the 365 about there might be pennies, but we're going
to keep it there. Let's add well as look at the panties. So they're
gonna be pennies. There are pennies, so
it could go on here, but we're going to round
it to two pennies, which is gonna be 3.36650 to get the pennies
Home tab number group. Adding the decimals. Then we could do it
the other way with the payment formula
because we saw that there's a payment thing here. So let's see if Excel has a function for the
payment thing. We're going to say
I think they do. I'm pretty sure I've
seen one before. I'm pretty sure I've seen
that before somewhere. So there's the
payment. There it is. Let's go shift nine. We're going to pick the rate. The rate is 12%. Once again, that's a yearly rate. So we've got to
divide that by 12 to get the monthly rate comma. Then we got the number of
periods, which is three, but those are years and
we're doing this monthly, so I'm going to take the
three times 12 to get the monthly periods comma. And then the present
value is the amount we're borrowing at
the current level, the current 0.11 thousand in B1 and enter
there, we have it. Once again, let's
add some decimals, Home tab number group
coupled decimals. And then let's
make it a positive number by double-clicking on it. I'm just gonna put
a negative before the PE flipping the sign
of the whole thing. There we have it. So there we go. So now, now we can do
an amortization table. So note the number of periods we have is
actually going to be equal to three times 12. So we're looking 36 months
in terms of the periods. So keeping that in mind, let's build our table out here. And I'm going to say, let's
bring this up from 01, and I'm going to
bring that down to 36 months by
selecting these two, grabbing the autofill, it doesn't matter
how long this is. You can do this for 360 months, which would be like
a 30-year loan. That's fine because you can
just drag it down like this. That's what Excel is four. That's what Excel is here, four. And then we can go
to the Home tab Alignment and center it. And then we're gonna
go to the loan balance and the outer column, this is going to be equal
to the eleven thousand, eleven thousand on the balance. And then we'll just do our
calculations once again, the payment we
already calculated, that's going to be equal
to this payment amount. And then we're going
to take the interests. And the interests is a little
tricky because we got it. We got to take
into consideration months instead of years, and they gave us the
yearly rate over here. Let's do this real quick. And the trusty
calculator over here, just so we can see it. We're going to say, we will
take the 11 thousand times. You could say that 12, which
will be the yearly rate. And that will give you the 1320 for a year's worth of interest. But then we're only talking
about a month here. So I take that divide it by 12. That's how I would normally calculate it with a calculator, because that's the
way that you're not going to get these
decimal number. The easiest way to do it
typically if you're doing that, but when you calculate
it in the formula, as we saw, we could do
something like this. 0.1 to the rate divided by 12
gives us the monthly rate, which happens to be 0.01 here, which is conveniently
given the problem, of course, we set it up conveniently nicely
so it's one per cent. But that can be a
little bit confusing. That's a monthly
rate and then we can multiply that times
the 11 thousands. So either way you want
to think about it, it's useful to think about it both ways when
you're calculating, depending on whether you're
using a calculator or Excel. Okay, So let's do that.
We're going to say this is going to be equal
to the 11 thousand. We're going to say
times the 12%. And that 12% would give
us the result per year. And then I'm gonna take
that and divide it by 12 to give us
the monthly result. And there we have it. So let's then decrease it. So this is the amount
we're paying threes. And by the way, if
you didn't divide by 12 and you came up with this, you'd say that doesn't
make any sense because the interest is
more than what I'm paying. That doesn't make an, oh, I didn't divide it by two. And then you're going
to divide it by 12. So that might happen. And then we've got the
365 minus the 110. So we're paying 365 minus 110, which is the rent portion, which we're not getting back. So we're going to reduce the
principal by only the 255. So then we got the equals the 11 thousand prior balance minus the reduction
of the principle. That's gonna give us the 10745. So if we were to record this, like in an accounting system, we'd have the loan
balance at 11 thousand, we pay cash goes down 365, but 110 of it is
interest expense, and the loan is only going
to be decreased by 255. So once recorded, the new
balance would then be 10,745. Alright, let's do
it a couple more times and then we will
auto fill it down. Don't worry, we won't do
this the whole way down. We'll just do it a
couple more times here. So this is gonna be the 365. The interest is
going to be equal to the new balance of a 1074
or five times the 12%, but that's the yearly rate. So we've got to divide that by 12 to get to the monthly amount. That's gonna be the 107, it being less than
the prior balance. We're going to take the
same payment of the 365 minus the decrease
interest amount that gives us an increased loan decrease
in which is going to be equal to the prior loan balance minus the decrease in the loan. We're now at the 10
thousand for 87. Let's do it again and we're
going to pay the same amount, which is the three
sixty-five thirty-six, the interest is now gonna
be the new loan balance to 10487 times the 12 per cent, but that would be
the yearly rate. So we divide that by 12. And then we're going
to subtract this out. We're paying the 365
minus 2102 interests, gives us the 2.6D. That means the loan balance, which was privately at 10
thousand for 87 minus the 260, gives us the new loan balance
of 10 thousand to 26. Let's do it two more times, two more times, and then
we'll do it the easy way. 365 payment interest
is going to be the 10 thousand to 65
times the rate of 12%, but that would be for a year, so we divide it by 12
for the monthly rate. Then we're going to
take the amount of the payment which is
still the same 365, but now the interest is
going down to the 1A2, so the decrease in the
loan goes up to 263. So now we've got the
new loan balance, which is was at ten
to six to ten to 26 minus the 263 new
balance, 99631. More time and then we'll
do it the easy way. One more time. We're going to say this
is gonna be equal to the 9963 times the
12 per cent up top. We will take that divided by 12 to get the monthly amount. We're down to a 100. We've got the 365
payment minus the 100 down means the decrease in
the principles at the 266, the prior balance
at the 9963 minus 266 gives us the 9697. Okay, now i'm, I'm
gonna go back and delete the whole thing so
we can do it the easy way. This is painful to delete
it, but it's okay. You don't have to delete it. I'll do it, but delete it. Let's do it again.
So this is going to be equal to the 365. Now this time I want
to copy it down. That number is outside my table. So I'm going to have
to absolute ties it because I don't
want it to move down. So I'm gonna select F4 and the keyboard dollar sign
before the E and the five, you only need a mixed
reference, in other words, $1 sign, but $2 signs
is easy to think about. So that's what we'll do. This
is gonna be equal to the 11 thousand on the
interest times the 12%. That 12% outside the table, again, don't want it to move
down when I copy it down. So I'm going to select F4 on the keyboard dollar sign
before the B and two. Then I'm gonna divide by 12, which is a hard-coded number. It will copy down as we
go as we want it to. So we're good. Move. This then is equal to
the 365 minus the ten. Both of those are
inside of our table. Both of them are wanting
to be moved down. No absolute
references necessary. This is gonna be equal to the 11 thousand prior
balance minus 255. Again, both those
inside of our table, both of them need
to be moved down to relative when I copy down. So nothing special needs
to happen there as well. Let's go ahead and select these three, will copy them down. Now if I wasn't confident and I am confident, so
I won't do this, but if I wasn't,
I'd copy it down just one cell and see if it
does what we want it to do. But since we're
totally confident, I'm going to copy it
all the way down. And the confirmation
number here should be that this last one should be
0 if we did it right. 0, just like I told you,
I told you it would. If I, if I double-check these, is it doing what
we expect it to? This is pulling that cell
all the way up there. Yeah. That's what we wanted. This is pulling that cell all
the way up there. Looks good. Looks good. And this end result is 0, making me think that things
have been done properly. So you can see the
payments the same, the interests goes
down over time. The loan balance than more of your payment is then a decrease in the loan
balance over time. And this becomes
quite significant, especially when
you're looking at deductible kind of things like a home loan where the
interest portion is deductible and it's important to be able to figure this out. You can then do because
you can then say, Okay, for the next year, this is the interest
we would be paying, which would be the
1146 and so on. If it was a deductible loan for a business,
same kind of thing. You might, might have tax implications that you have to be taken
into consideration. It's also just
useful to see what is actually happening in terms of how much you are
paying for rent interests, in essence, and how much
is being paid back with regards to the loan
principal amount. Okay, let's do it again. Or one more thing with a tables. Remember this is a table. The backing into the table, you got to do the reverse format to get to the table amount, but I'll set it up in the
same format here we would say this is gonna
be the payment, which is what we're looking
for times the table. This is what we usually
do. It gives us the present value of an annuity. Now we already know
what the end result is. That's the 11 thousand. We can find the amount from the table and then
back into the payment. So the new twist, however here is that
we're not looking for years and yearly rate. We're looking for months, which is gonna be 36 months. And that's why we
don't often use the tables or y book problems, avoid monthly rates because three years already has you almost to the end of the table. The end of the
table only goes so far and I don't even have
a table Hold on a second. It's over here
because I see why. Okay. So it only goes down to 50 and then it starts
skipping periods down here. And the rate or even rates
and they don't go below, below 1%, which
is also a problem which we made
conveniently to be 12%. So the monthly rate
is simply one. So it's nice to have
nice even rates. In other words, if
you're using tables. But in real life it doesn't
really matter because Excel can take care
of uneven rates. So in other words,
we're looking for then 36 periods and
we're looking for 1%. And so when we go
down to the table, note that we've gotten you've probably gotten used
to the periods, meaning years and the percents
being yearly percents. But what you got to keep
in mind is that it doesn't matter what the two are
as long as they match. So if I'm seeing these periods
as months, that's okay. As long as I see
the interest rates as the monthly interest rate, if I was to look at
these and months, looking up 36 months, and then use the
yearly rate of 12, that would be a problem. But if I convert these
two months using the 36 months and I use the monthly rate of
one, then I'm okay. So that's gonna go down here to the to the 30.10830.10830.108. And then we can back into this amount now
because I can say, well, if the yellow number
times this is that, then I should be able
to say that this is the 11 thousand divided
by the 30,000.108, giving us that three
sixty five thirty-five. Again, we could double-check
it down here by recalculating that
365.35 times the 3D, 0.108 equals 11 thousand. Let's blue a fire that one
just to double-check it. So there we have it. So we've taken this, we've basically got our
payment amount on it. Very useful, very useful to this number note you
can find a lot of tools to help you out to
figure out the payment. But using Excel, I
think, is the easiest, most transparent thing to do that you can
understand it with, then take that payment, prove it in your mind, and get a better understanding
of it by putting in, into an amortization table where the end
results should be 0, which should give
you some confident that you set up your
table correctly. And that'll give you
a lot more context on which to make decisions
related to car loans, home loans, and
that kind of thing.
15. Annuity Due or Annuity Beginning Period: Personal finance practice
problem using Excel annuity due or annuity where the payment is due at the beginning
of the period, prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information
on the left-hand side, we're going to populate
that into the blue area. On the right hand side, we're looking at an
annuity situation which is a series of payments
on normal annuity, usually assuming the series of payments happens at
the end of the period. Now we're going to basically
assume the payments are happening at the
beginning of the period. We got the payment amount, which is gonna be
the $1 thousand. We've got the rate at the 5% that yours are
going to be six years. We're gonna do a future
value calculation of an annuity and we'll do one for the standard annuity and
look at the difference. If we were to calculate the annuity due or the
series of payments happening basically
at the beginning as opposed to the end
of the timeframe. So let's first do that with just simply the Excel functions, normally the normal
standard annuity. If I'm looking at the
future value of annuities, meaning I'm going
to make a series of payments every year, assuming at the end
of the year for six years at a 5% rate, where will we be in
terms of future value? We're going to say this is, I'm going to start
with a negative to flip the sign at the start, which is going to be
future value shift nine will pick up the rate, which is going to
be the 5% comma, the number of periods is
going to be the six periods, which is going to be the years, and then comma, and the payment is going
to be the 1 thousand. So this is what we
have seen in the past. Notice that we haven't been using these other
two components here because by default we're
at the standard annuity. But notice if I hit
a comma, again, I'm going to say comma, that gives us the present value. We don't have one comma. Again, that takes
us to the type. Now the type says here, the default is basically end of the period versus the
beginning of the period. So by default, typically having this end of the period
or 0 calculations. So in other words, if I was to hit the 0 calculation here, we then have the type
added and then Enter. That'll give us this 1008 O2. If I double-click on this again, and I remove the
0 and just remove these last two fields
which are not required. It will by default give us the same calculation
of the 68 O two. Now, if I want to change that, then I can use that
type field to make the adjustment away
from the default, which is two, which
is to say it's at the beginning of the period. Let's see what that
would look like. So it's going to be a
same starting point. This will be the future
value shift nine, the rate once again
at the five per cent. Then comma, we got the
number of periods. The number of periods
is going to be six comma and then the payment, the payment is going to be the
1 thousand and then comma, I'm not going to put
a present value here. I'm going to put
another comma and note the present value
is typically there when you're not doing an
annuity where you would skip the payment and
use the present value. This time I'm going to
skip the present value to get to the type calculation, which I do want to
use because I want to remove myself from the
default and go to this one, which is indicated with a one, the beginning of the period. So I'm going to select
that one that'll put a one for the type. Now, we could close it up or we can leave it as is and then say Enter and we get them
to a different result, a larger result, because
we're assuming here then that the payment went in at the beginning of the period. Let's see if we can make
some more sense of this by basically putting these
two into the table. We'll start at our first table doing the standard kind
of annuity and then compare it to the one of the payments happened at
the beginning of the period. So note with a standard annuity, I'm not going to put
a time period 0. I'm going to start at 12. I'm going to select
those two cells, put my cursor on
the fill handle, drag it on down for
our six periods, Home tab Alignment, center. And then the payment
is going to be equal to the 1 thousand at period one. Notice that no interest
is going to happen, no increase in the value due to the fact
that we're assuming that happened at the end of the period one, end of the year. In this case, the investment at the end of the year will
still be the 1 thousand. Then we're going to calculate the increase which would
be interest to whatever the increase would be increased in value if it was stocks
or something like that. In the next period, which
would be the 1 thousand times, we're going to save
the five per cent. I'm going to select
F4 on the keyboard because I will copy this down since we've seen this
one in the past. So F4 dollar sign before the B and the two before
the B and the two. And that would mean
it's absolute, it's not going to move down. You only need a mixed reference, but an absolute references
easier to think about. About 50. Then we're gonna be
seeing the payment is the same at the 1 thousand. That's also something I
don't want to move down. So I want to make it
absolute by selecting F4 dollar sign before
the B and the one. Once again, you only need a mixed reference but
an absolute works. Then we're going to have
then the investment, which is gonna go up by both
the 1 thousand and the $50. And that's gonna be calculated as the 1 thousand
we started with. And J2 plus, I'll
say plus the SUM, the sum shift nine, left arrow of these two
items to 50 plus the 1 thousand plus 1 thousand
closing the brackets. And there we have the 2050. I'm simply going to
copy those cells down. I'm going to select these three, put our cursor on
the fill handle, auto-fill and copy that on down, dragging it on down. That gets us to our end
result of the 6,008 O two, we would have put in six
payments given us the $6 thousand over the six years and the amount of increase
we had if we sum this up, would be the $802. Now, this one will
be a little bit more confusing if we think about the payment that happens
at the beginning. So I'll set the table up two different ways so
we can look at that. The first way, we might do
the same kind of process. We're going to say we've got 01. I'm going to start at 0
this time instead of out1. And copy that down. I'm going to copy this down
to six periods that I'm gonna go to the Home tab,
Alignment and center. And then I can
think about periods 0 as basically the
starting point, meaning the end
of period 0 would be the beginning of period one. So the payment happens at
the beginning of the year. You're thinking, which
I'm going to say is that the end of period 0. So you got the same
kind of starting point. So I'm gonna say
this will then IQ actually let me put
that in the payment. The payment here is going to
be equal to the 1 thousand. And that means the
investment is gonna be the same at the 1 thousand
at that point in time. And then I'm going to
say in period one, then, now we're actually going to be calculating interests
in period one because we're assuming that we had it at the beginning
of the period. And therefore interests
will be calculated for the year of period one. And we're indicating
that by having the investment amount
at the beginning of the prior period
so that we can have a similar table formatted. So let's see what
that would look like. This would be equal to
the one thousandth times. I'm going to scroll up
and pick up the 5%. I don't want that cell
to move down again. So I'm going to select
F4 on the keyboard, dollar sign before the B and to making it absolute so
that when I copy it down, it does not move down. Note you only need
a mixed reference, but the absolute works. Then the payment is
going to be equal to, and I'll pick up the 1 thousand. I want to make that absolute. So when I copy it down, it doesn't move down. F2 for on the keyboard, dollar sign before
the B and the one. And then we have a
similar calculation here. We've got the prior amount, 1 thousand plus the sum of shifts nine left
arrow holding down shift the 50 and the
1 thousand shifts 0 it up 1 thousand plus
1 thousand plus 50, given us the 2050, then I can copy this down. This is a similar format, just kind of a different
starting points selecting these three cells. We're going to
copy that on down. Let's do the good
old copy down here. And so there we have it. We
have the similar layout. Now, you can say, well, this doesn't quite make
sense because now I've made seven payments
here of 7 thousand. And so what we're gonna do is basically delete this last one. And that'll give us two
are balanced of the 7,142. So it's a little bit
staggered in the format, but hopefully that
might be clear to you. You will do, we'll try it
a different method to, so that might click
a little bit more. But remember that this period 0 actually represents the
beginning of the year. So we put it at the beginning of last year of the 1000s so that we can have
the same structure and then calculate
this the same way. And then the $50 is being calculated on the 1 thousand
that we put in period 0. But we're kind of
assuming happened at the beginning of period one, earning the 50 thousand
in period one. And then we had
another 1 thousand, which is a little confusing
given the fact that, that 1 thousand would be there at the beginning of
basically period two. So in other words, at
the end of period one, you really got the 1050 that would be in there
as you accumulate it, the interest, this
payment then what basically happened
at the beginning? You can think of these
two days at the same day, right at the end
of the first year, the first day of
the second year, the next 1 thousand going in, bringing the amount up to 2050, calculating the interest on that would be at that one oh, three. And that would be what
we would have at, at year two, then the 1
thousand would be put in. Again, we're really, what would happen is that the
beginning of year three, you put the 1 thousand in at the first day
we got up top kind of imagining the
end of year two and the beginning of year three
being basically the same, and so on and so forth, until we get to your six here, which once again does not
have a payment because we put the payment at
the end of last year, at the end of year five. We can calculate the interest on it and then we get to
our ending balance. So this structure
is the same format. We can come up to a little
bit more complex of a table, which might give us a
better grasp of this. So let's make a little bit
more complex of a table and see if that makes it
a little bit more. This time we're going to
start with year 12 and so on. Same kind of format at
the starting point. And I'll pull this down. And then we're gonna go to the Home tab Alignment
and center it. Then we could say,
okay, let's let's start the payment at the
beginning of the year. So I'm going to say this equals
the 1000-dollar payment. I'm going to select
F4 on the keyboard, F4 to put dollar
signs and Enter. Then we're going to stay
at the start of the year. And we'll say the start of
the year balance versus the Andy the year balance of the start of
the year balance, which will be that $1 thousand. And then we're
going to calculate the increase for
that time period, which would be from January
1st to the end of year December 31st, all
in the same year, we're saying this is
gonna be equal to the 1 thousand times and we'll
scroll on over to the 5%. I'm going to select F4 on the keyboard to
make that absolute. So that times the 5%. And then we have the end
of the year balance. So we now we've got
two year balance, beginning and end equals
the sum of the 1050, then we can say, alright,
the payment for year two is going to
happen at January. It's going to be the same. I'm just going to say equals
the one above it this time. And then the year start
balance will then be equal to the 1050 plus the 1 thousand we put
up in the beginning. So that's our January
balanced, January 1st balance. It's going to increase during the year January
through December by this equals the 2050 times. I'm going to scroll all the way over to that five per cent. Again, the five per
cent, and enter. So there we have that. And then the year-end balance
would be equal to the sum of the beginning balance plus the three oh,
one, oh three. About getting us to that 2153. And then we have another payment which would be 1 thousand. The starting balance
would then be equal to the to the 2153. I'm sorry, hold on a sec. The starting balance yeah. It would be equal to the
2153 plus the 1 thousand. And then the increase
would be equal to that 3,153 times scrolling over
the five per cent up top. And then we'd have our
ending balance equal to the sum of these two numbers. And there we have it. Let's do it one more time. And this time we'll figure that we're going
to copy it down. Note that I didn't use an
absolute reference here, I'm equally in the one above it. That's also another method if this whole column
will be the same that you can do instead of using the absolute method,
absolute value. So I'll keep that the year start balance is going to
be equal to this number, the prior year-end balance
plus the 1 thousand payment, that's the January balance. They're both within the table. There's nothing I need to do for absolute references there. Then the increase is
going to be equal to that 400110400310 times. I'm gonna go all the
way left and then up to that 5% that is
outside the table. So I'm going to
make it an absolute reference selecting F4 or putting a dollar sign
before the B and the two. And then over here, the year-end balance
is going to then be equal to the sum of these two. There's no nothing
outside the table, so I should be able
to copy that down. Then if I select these
four columns and put our cursor on the fill
handle and drag that down. Then we get to that 7,142. Once again, this one might
make a little bit more sense, but obviously we
had the structure, the table a little bit differently
than we had over here. Or how you might
structure the table in a normal type of annuity
and just want to point out that obviously they're the same kind of thing
that's happening is just basically when you're calculating
the payment to be made, be made at the beginning
or the end of the period.
16. Present Value Monthly Periods: Personal finance
practice problem using Excel present value calculation
with monthly periods, prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow
along note that we're in the practice tab as opposed
to the example tab. The example tab in essence
being an answer key, information on the
left-hand side get to populate that into the blue area on the right-hand
side, the question says, how much would we
have to invest to be, to have in the future 25 thousand rate of
return at 24% years, three years, but this time
not compounding yearly, but rather compounding monthly. We want to have in the future, 25,024% is the rate of return. That then is the
yearly rate of return, not the monthly rate of return. When we look at the tables, you'll be able to determine
why we picked 24%. And if you're working
in a school setting, you can get an idea of the limitations that a
school might have if they're trying to limit
you to the use of the tables in the way that
they format their problems. And then we've got three
years that we're going to have to break out into months. So let's first do that. We're going to say, okay,
we're not compounding this yearly, we're
compounding monthly. That means we have to calculate
how many periods we have, which is going to be three
times 12 or 36 periods. Now that already when we do our running balance calculation, you could see how much more
complicated that will be, because we're going to
have to compound it 36 times as opposed to three times if it was
compounded yearly. That then again, is one
reason that many practice problems we'll focus in and
0 in on yearly calculations, even though many kind of real-life settings
compounded monthly. So if you're in Excel, once you have the concept down, not really a problem to
be able to copy and paste this information down
for longer periods. Let's do the present
value calculation. Note that this 25
thousand, the future, what we want to do with
bringing it back to the current time period to
see how much we can put in today that would be earning
24% compounded monthly for 36 period or three years
to get to that end period. That's why it's going to be
a present value calculation. I'm going to do
it fairly quickly because we've seen it before, but I'm going to
highlight the new things that will be involved. The major things
you want to keep in mind is that that rate that's been given twenty-four percent
is usually a yearly rate. And that's gonna be similar
if you're talking about like a loan for a home loan
or something like that, which you know, is
a monthly payment. Generally, they're going to quote it as if it's
a yearly rate. They're not going to give
you the monthly rate because the monthly rate to be quite small and confusing and whatnot. So they'll give it to
you in a yearly basis. But when you do the calculation, you need the monthly rate, which means it's
going to be that 24 divided by 12, in essence. Now, again, the software
can do that quite easily. So let's see what
that will look like. It's gonna be negative to flip the sign present
value shift nine, then we'll pick up the rate, which is going to be that 24, but that's the yearly rate and we're doing monthly periods. So now I got to
divide that by 12. That's the new thing that
we gotta do in terms of an Excel function comma
number of periods. Now it was three years. They might give you three years, in which case you would
take three years times 12. Or we already did that here, which is 36 periods. So 36 periods, comma, and then the payment that
would be for an annuity. This is not an annuity
present value. This is a function of one, present value of one, so two commas bringing us
to the future value. The future value
where we want to get to is the 25 thousand, picking up the 25
thousand and enter. So we're at the 12 thousand
to 55 or 56 about, Let's add some decimals Home tab number group
coupled decimals. So we're at the 12
thousand to 5558. Okay, so then let's do
this with a formula basis. Same kind of thing.
This is what you would probably do in practice. And then you would
probably wanna do a running balance
in practice. But before we get to
the running balance, let's do the table that
we're gonna do in Excel. But it'll be similar to
an algebraic format, meaning we'll do the
formula down here. So let's go ahead and
hide these cells up top. I'm going to put my cursor on C, drag on over to E, right-click on those
cells and hide them. We're gonna look at this formula which you could plug
in algebraically, it's still just a
straightforward present value. The future value over
or times one over would be the future value of
25 thousand over one plus r. But now are, is not 24%
but 24 divided by 12. We need the r that matches
the number of periods. And then to the periods of 36 periods which are
monthly periods, making sure that
the periods then 36 periods match the rate, which is not the yearly rate, but the monthly rate. So in a formula it
would look like this. We're going to say,
all right, here we got the outer column is
the 25 thousand. We're going to bring inside
this inner calculation, as we have seen in the past, for the denominator, which
would be one plus the rate. But now the rate, There's
the new thing is gonna be equal to the 24 divided by 12. I'm going to make that a
percent Home tab number. We're going to
make it a percent. We can add some decimals and obviously rounds to
two nice and evenly. Now note that I used 24 per cent in part so that it does round, nice and evenly to two. You can see that if we had a yearly rate of 5% or
something like that, then the monthly rate would
be something kind of ugly, something ugly to basically
talk about, right? That's why a book
problem will be limited to something like
a twenty-four percent. If you're going to use
the tables, obviously, you can still calculate this
in Excel without a problem, no matter if it was an
ugly number or not. But also note that when
you're talking about rates, that's why we don't use monthly rates when
we talk about them, even though will be
compounding monthly. Because again, the yearly
rate makes more sense, It's easier to deal with. So let's go ahead and underline that will go to the
Home tab font group. And underline, There's our 2%. And then we've got the, we're gonna call this
the one plus the r. One plus the r. And this is going to be equal to the SUM Shift Up Arrow,
adding those up, making that up per
cent Home tab numbers, obviously that would be 1.02 and a decimal or percent
ties in it 102%. And then we're gonna take that
to the power of n periods, periods to the power of n and n. Another new thing here
is not three years now, but rather 36 months. And so as long as these months
match up with the rate, same thing, rate,
the monthly rate. In this case, we're
good and we're gonna go home tab font group
and underlined. And that's gonna give us then
the result of the 1plus, our shift six carrot
to the n periods. And that's going to be
in the outer column, which is gonna be equal to the one or 2% shift
six carrot to 36, and that's gonna give us two. Let's add some decimals. Home tab numbers,
destiny symbolized. Then we're gonna
go to the Home tab font group and underline it, and that'll give us our
present value, present value. Finally dividing this out, this equals to 25 thousand divided by that desk
normalized number, adding a couple of decimals, Home tab numbers coupled
decimals, there we have it. So we've got that same 12
thousand to 5558, again, that we'd have to put down up front compounding monthly for three years or 36 monthly
periods at 24% the yearly rate, which would be 2%
monthly rate to get to the 25 thousand
after that time period. Okay, so let's go
ahead and indent this, selecting these items Home
tab Alignment, indent. Let's indent this one again. Alignment and dent. Okay, now let's do this again. This time. Let's do a running
balance table, which again it's a longer period because it got monthly periods. But that's okay because
we have what's known as a spreadsheet in
Excel, makes it easy. So we're going to then
put our cursor on F, drag on over to I, right-click and hide,
right-click and hide. And then let's do this one. I'm going to say this
is just going to go from one to start at 001 to selecting those three. And then we're going to
auto fill it, fill handle, dragging it all the way down
36 periods, no problem. Because, because
Excel, that's why. And then we're gonna
go to the Home tab, Alignment and center. And then we're going to say that the investment that we're
going to start with, which I'm going to
recalculate again to start at the starting point and
prove that we will end than at the 25 thousand. So I'm gonna do it
again negative, do it with our formula present value shift nine rate is the 24, but then I got to divide
it by 12 because I need the monthly rate comma number of periods is going to
be not three years, but 363 times 12 comma. And then the payment is
going to be no payment. What am I doing to two commas because it's not an annuity, future value 25 thousand. And there we have our 12
thousand to 56 again. And now let's do our
interests calculations and we'll do just a
couple of them here. We won't do it 36 times. And then we'll drag it on
down with the autofill. So this is gonna be equal to, and I will do it a couple
of times because again, this one will be a little
bit different due to the twenty-four percent
needing to be monthly rate. So in other words, if I
took that 12 thousand to 56 times 24, that would be the
rate for a year and I got to divide it by 12. And that'll give us the monthly. I think it's worthwhile to
kinda look at this two ways. Note that if I was to do this in a calculator for a problem, I would do it this
way, 12 thousand to 56, about times 0.24. And that would give
us about this. There's rounding involved
and then that would be for a year interests if
that was for a year, but it's only for months. So divided by 12, that would
be the monthly amount. Or, and this is how you
think about it in Excel. You can take the 0.2
for the monthly or a yearly rate divided by 12
given you the monthly rate, 2% then times the 12 to 56. And you'll get to
that same result about rounding involved. Alright, so then that means the investments can be equal to 12 thousand to 56 plus T2 45. Let's do it a couple more
times and then we'll go back in and auto fill it. So we're going to
say this is now that 12 thousand to 1200502 times
the twenty-four percent and then divide it by 12. And then this is going to
equal the prior amount, that 12,005 over one plus d 250. Let's do it two more times here. This equals the 12,751 times
the twenty-four percent, But then divide it by 12. This equals the amount above it plus the amount to the left. Now we're at the 13,006 and
this is gonna be equal to 13,006 times the twenty-four
percent divided by 12. This will equal the 13,006 plus 260 and so on and so forth. Now, I'm going to delete
this and do it again, but this time keeping in mind that we're going to
auto fill it down and making any absolute references
that we have to do it. So we'll delete this,
selecting this item. No, don't delete it. Don't let God all that work on. Okay, let's do it again. This is going to be equal
to the 12 thousand to 56 times the Twenty-four. Twenty-four is outside of
where I want to be here. I don't want it to copy
down when I auto fill. So I'm going to select
F4 on the keyboard, putting a dollar sign
before the B and four, you only need a mixed reference, but an absolute will work, then divide it by 12. That is a hard-coded
or typed in number. That one will continue on
when I copy it down as well. And then this one is
simply going to be the one above it plus the one
to the left of it. It doesn't have anything
outside the table. Therefore, I want them both
to move down relative, so I don't need to do any
absolute references there. Then I can just
select these two. And once again, I don't
care how many periods there are because I can just grab the fill handle
and drag it down. Doesn't even matter. You can have we can
do a whole mortgage, 360 monthly payments
for a 30-year mortgage, which we might do later. And whatever. I don't care why, Because Excel, that's y. And then we get to
the bottom line here, that's gonna be
the 25 thousands. So we get to 25 thousand
proven to us that we do indeed start at the
12 thousand to 56. If we compound monthly
using this calculation, we get to the ending
0.25 thousand there. Let's do it with our tables. So if we do the tables here, we got the investment. The investment is
going to be the 1225 thousand that we're
gonna present value. Now again, this is another one where you look
at the tables. We've been using the tables. And I'm sorry, I'm
saying again a lot. I notice I'm saying again a lot. So if that's annoying
anybody I'm working on, I'm trying I'm trying to stop. I'm trying to stop. But we got the percents up top and the
periods on the left, the periods before
we've always thought as years and the percents
as yearly percent. So as long as those two
things match, we're okay. But this time we
need 36 periods, which are monthly periods. And therefore we have to
match the related percent, which needs to be
a monthly percent, which would be the 24 divided
by 12, which would be two. Now, note that if this was something like five
or something like that, you wouldn't be able to find the percent here because one, it wouldn't be even and they
only have even percents. And two, it would be
smaller than one. So if because it's
a monthly percent, so notice how severely
limited the tables are when a practice
problem starts dealing with monthly time period compounding as opposed
to yearly compounding. That's why most book problems
will simplify problems that might often be monthly
in real life to yearly. So they can force you
to use the tables. That's not a problem
when you're, when you're using Excel, but if you're forced to use the tables, that is a problem. So you'll see percents
like twenty-four percent, because if I divide that by 12, that gives me a
nice two per cent, which is nice and even that I
can then use in the tables, don't let that limitation make you feel like that's a real
limitation on in life. Because normally
people don't take your calculator away or your Excel worksheet
when you're doing stuff. And so it's not a problem, therefore, but when you're in a book problem
tables, that's it. Okay, so we've got the 236, which is way down here. Notice I'm limited
to like three years. I can't go too far over that
because it only goes to 50 payments and it's separated, kind of weird down here because five years would be
60 months, right? And a monthly
period and whatnot. So in any case, we're limited to the
number of years if it's a monthly as well with the table. So 36 I said it was
thirty-six point 4.4909020 to adding some decimals Home tab
numbers destined to moles. And this is from the table. And then we're gonna
go to the Home tab font and underline. And that's gonna give
us our present value. Present value,
which will be equal to the 25 thousand
times the 0.4902. Adding some decimals by going to the Home tab numbers
coupled decimals. Notice this number
slightly different, of course, than
what we got here. Well, let's unhide some cells. Double-check this due
to rounding tables, rounded to four digits. Okay, let's put our cursor on, be dragged on over to k b, k, right-click and unhide. So now we've done it this way. We've got the 12
thousand to 5558. We did it this way with the
formula 12 thousand to 5558. This is basically the
amount that should in essence be on actually,
that's not the amount. If you want the
amount on the table, you could calculate it this way. It will be the 12 thousand to 5558 divided by the 25 thousand. Adding some decimals,
Home tab numbers. Decimals, that's the amount
that would be on the table. Notice it doesn't
stop at four digits. When we look at the table,
it does stop at four digits. That's why we have this
rounding difference between the calculation and
the table calculation. Note that's not a
problem in real life due to it being an
estimate in any case. So it won't affect
our decision-making process most of the time, but it will be some
difference that a school could use to force you to see
that you use the table. And if you don't, they can
say See you didn't even, you didn't follow
the directions. F. And so you don't
want that to happen. So be aware of that.
17. Present Value Annuity Monthly Periods: Personal finance practice
problem using Excel, present value of an annuity
using monthly periods, prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information on the left-hand side
going to populate that into the blue area on
the right-hand side, the information says,
how much would have to invest to be able to
take out each month? $1500 for three years. So for three years, we would like to take
out monthly $1500, the rate of return
is going to be 12%. Now note what we're looking
for is a lump-sum that we can then have that's going to be generating interest on
it as it's in there, but then we're gonna be
pulling out 1500 from it. So this is actually
a present value type of a calculation of an annuity. So we're thinking
of the annuity, which would be a
series of payments of the 1500s over the three years, but on a monthly basis. So we do this on a
monthly process that we're taking out
1500 each month, present value them to the starting point at
this point in time. And then think and then
we can basically prove that with our running
balanced type of calculation. So in other words, the number of months that we're looking
at is going to be the three times 12 or 36 months. So we want to be able to take
out $1500 for 36 months. Let's do our present
value calculation. It will be the present value of an annuity type of calculation,
now slightly different. So we've seen these before. If you want to do
this a little bit slower for a yearly
present value, take a look at prior
presentations. We're going to focus
in on the new thing. So we'll say negative to
flip the sign instead of equals present value shift nine, the rate is gonna be the 12%, but that rate is a yearly rate. Notice we generally
assume that we're given the yearly rate unless
told otherwise, even though we're
gonna be working with something that's gonna
be on a monthly basis. And that's generally
what will happen. That's just the convention
of how we use rates. Because if I was to
give monthly rates, oftentimes you would have a
small, ugly looking rate, although this one would be 1%, 12 percent divided by 12 months, which is nice and even, which is why we picked it. But in practice, if it was
like a 5% yearly rates, you can see the monthly
rate would be a problem. So we're going to divide that
by 12 in our calculation. That's the new thing. Comma number of periods is
not gonna be three years. But if that was
what we're given, we would be three times 12. Or we can just we've
done that here, it's the 36 periods
then making sure that the periods
matches the rate. And then comma, now we
are doing an annuity, so we're looking
at payment here. So the payments are
gonna be 1500 and Enter, that'll give us the 45,161. So the idea then being that if we had the lump-sum of 45,161, then we should be able
to take out 1500 for three years each month of those three years or
for 36 monthly periods. If we're earning a return on
everything that's still in there at the 12% yearly rate, which would be 1% monthly rate. So let's do a running
balance calculation to kind of prove
that to ourselves. Now I'm gonna go ahead
and hide some cells. I'm going to put my
cursor on column C, drag on over to E, let go and right-click. Let's hide these cells. Right-click it doesn't want to, right-click, isn't staying
there and then hide. Okay? So then we're going to say 012 and we're going to
drag this all the way down to 36 periods, noting that we have
more periods here, But if we're using Excel, not a problem, it
should be okay. So we're gonna put our cursor
on the autofill handle. Left-click, drag it on
down to 36 periods. Look how easy that is to do. And then we're gonna
go up top Home tab, Alignment and center that. It's just incredible, just incredible the
ease at which we could do that with the
tools at our disposal. So then we're gonna,
and I'm gonna call this the increase. This is the increase. And then I'm going to
say the investment, I'm going to recalculate
it again just to practice it. It's
gonna be negative. Present value shifts,
nine, rate 12%. But then I got to divide that by 12 because I'm looking for the monthly rate which would be 1% comma number of periods
is not three years, but three times 12 or 36 periods because their monthly periods, comma payment 1500s, and enter. So there it is,
again, about 45161. Let's go ahead and then
calculate our increase. So whatever still in the
annuity would be the 45,161 times the rate of 12%, but that 12% is the yearly rate. So I got to divide that by 12. That's the tricky new thing. That's the tricky new twist. Note that when calculating
that you might do it this way. 45161 times the 0.12 or 12%, that would be the
interest for a year. That's what I would first do in a calculator if I had a
paper and pencils usually, and then take that
and divide it by 12. That would be the
monthly amount about or you can basically take than the rate 0.12 divided by
12 to get the monthly rate, one per cent, which is kinda
what you do when you think about an Excel function
as we just saw usually. And then multiply that times the 45161 and you get
about the same number. So let's go then. We have a payment,
so we're going to be taken out each time. I'm going to make this a
negative by saying negative instead of equals and
point to that 1500. And then we had the
prior investment equals the one above it. Plus, and I'm going to
say the sum of using the trustees some
function shift nine, and I'm going to add these
two together, summing them. That's what somebody means. Even though this one will
basically subtract because it's a negative number of
closing up the brackets. The 45161 plus the 452 minus the 1500s
gives us the 44113. Let's do that a couple
more times before we use the autofill
to do it the easy way we're taking now the 44113
times the 12% down here, but that's the yearly rate. So we're going to
divide it then by 12. That's the monthly amount. We got the same negative 1500
were taken out each month. So we're increasing or earning
100 or 441 each period, but we are taking out
more than we're earning. Of course, bringing down
the investment amount, which means that our
earnings are gonna go down as we go on each period, although we still have earnings
each time we compound. So this is going to be equal
to the 44113 about plus the SUM shift nine left arrow holding down shift
left again shift 0, closing up the
brackets and Enter. Let's do it two more times here. This equals to 4554
times the 12%. That's the yearly
rate dividing that by 12 for the monthly amount. This is gonna be the
negative of the 1500s. I'm going to select tab
to go to the next cell. This equals the item
above it plus the SUM, the sum shift nine left arrow holding down
shift left again, closing up the brackets Shift 0. Let's do it one more time. This equals to 45985 times 12%. That's the yearly rate
divided by 12 to get to the monthly amount Tab to go directly to the
cell to the right, negative to make it a
negative number of the 1500s, this is going to equal the
amount above 4585 plus the SUM shift nine left arrow holding down shift left again, shift 0, closing it up. There, we have it. Now let's do the
whole thing again, but the easy way so we
can auto fill it down. So I'm going to delete
what we've done thus far, selecting these atoms. No, don't, don't, don't do. Yeah. Oh my gosh. I can't believe you
delete it. That's okay. We'll do it again
because we're gonna do it the easy way this time. This is going to be equal to the 45161 times, times the 12%. Now that 12% is outside
of the table here, so we want to make it an
absolute reference by selecting F4 on the keyboard dollar sign before the B and the eight, you only need a mixed reference. But an absolute reference
is easy to think about. Then we're going to
divide that by 12. That's what we call a
hard-coded or typed in number that will also copy down
as we auto fill down. So this is going to be
equal to the payment, I'm going to say
negative of the payment. That payment also
outside the table. Therefore, we want to make
it absolute because we don't want it to move
down when we copy down. So I'm going to select F4 and the keyboard dollar sign
before the B and four. Then this one is
going to equal the 45161 about plus the sum, SUM shift nine left arrow holding down shift left
again and shift 0. And we'll close that up. Now there's nothing here
that's outside the table. So although this is our
most complex formula, all within the table, I want it all to move down
relative when we copy it down, so no absolute
ties in necessary. Let's go ahead and
select these then. And we're just going to
copy it all the way down, putting our cursor
on the fill handle, dragging it down 36 periods. Right on, down, there we go. And the end result at 0, indicating that it looks
like we did it correctly. So that's going to
give us an indication. So that's basically what
you'd want to do in practice. Now let's do a book problem
types of things where we will do with a formula and then we'll do
it with the tables. So we're going to put
our cursor on column F. Let's drag on over to j. Let go right-click, and
let's hide those cells. Let's hide those
sales. My right-click, it keeps doing something
funny like that. I want to hide those, want to hide those cells. Okay, so then we're
gonna do this. You could do this and
just plug it into the formula down here, which is kind of
an ugly formula. So it would be the present value of an annuity
equals the payment, which would be the 1500 times one minus one over one plus r, which is gonna be the
12% divided by 12, or one per cent to the
number of periods, which would be three times 123 years times
12 or 36 periods. Those are the new things.
That's why I'm saying it kind of emphasis like with
an emphasis on it, because that's the new
thing from the light. So that's the new stuff. So the 37 next period's divided by R, which is the rate, which is
12 divided by 12 months, or 11 per cent. So let's put that
into our formula as we've done in the top, making a table out of it. Because that's
always good times. And then we'll emphasize the new stuff again
in our table. So this isn't new stuff. This is the same
stuff that 1500, but making sure that's our
monthly amount though. And then we have the numerator. And I'm going to put the
calculation of one here. Which is that one right there. And then I'm going to call
this numerator to numerate, numerate Tor to, which
I'm just going to put one here and that's gonna
be this one right there. And then we're going
to put this as the denominator of
one plus r shift nine shifts six carrot to the n periods colon because we're pulling
up to the inside. One is gonna be here. The rate is going to
be our right there. Here's the new thing. Here's
where the new thing happens. It's going to be
equal to the 12%, but that's the yearly
rate divided by 12. Let's percent defy that
by going to the Home tab number group percent of phi. It's 1%. That's why we made
it nice. And even again here with the 12
per cent yearly rate, obviously if it was something
like 5% or something, we have some small, less than one decimal
monthly percent, which is okay for Excel, but it can be a little confusing to discuss
and talk about. Then we're going to
go to the Home tab up top font group and underline, this is gonna be what
we'll call our subtotal, subtotal, a SUB TO Tau, which is going to be
equal to the SUM, the sum of these two items. And we'll make that into
a percent Home tab number per cent defy were
at the 10, 1%. We're going to take that
to the number of periods. We're down here at the
number of periods now, That's going to be to
the number of periods, which is n, and our
calculation which was 36. This is new, not three years, 36 months, 36 months
for three years. And we're gonna go
to the Home tab, fonts group underlying. And then that's gonna
give us then our 36. That'll give us our total here, which was the one plus r shift nine to the end but
without the colon, because this is the end result which we are going to bring
into the outer column, which will be then the
one-on-one percent shift six carrot to
the 36th periods. And that gives us one, which we're going to
add some decimals to Home tab number, cinema lysed. It's been destined to mobilize. So there we have that. Let's do some indentations here. Let's go ahead and
indent this whole thing. Home tab Alignment and dent. And then let's
indent this thing by going home tab
Alignment, indent, and then let's
indent this and go home tab Alignment in den, that looks way better, that looks way better. So then this is gonna
be the numerator. And then I'm gonna say
this is a subtotal, so SUB TO tau. And we'll bring this
to the outside. And so now we're going to go
ahead and divide this out. This is going to be then the one over that desk
normalized number. We're going to add decimals it by going to the
Home tab numbers. We're going to
normalize that one. Let's bring that one out too. So I'm going to
indent that Home tab Alignment and indent that
all the way out here. I'm going to underline
this number, font group and underline. And now we've got the numerator, which so the end of
the new moraine torr, which is now going to be one minus this whole thing
represented in this column, one minus that whole thing. Let's underline here, Home
tab font and underline. This is gonna be
equal to the one minus the destined
them allies number, adding decimals to it, Home tab number, deaths
and normalizing it. And then we're going to
have the denominator, denominator, which is
gonna be the rate. And that's simply going
to be equal to the 12th, but that's the yearly rates. We've got to divide
it by 12 to get the monthly rate or 1%. Home tab numbers per
cent define to that 1%, underlining it by going
to the font group and underline that's gonna give us another and we'll
call it a subtotal, bringing that to
the outer column, and that'll be this
whole piece here now. So we're gonna, we're
gonna divide this out. This equals the numerator
divided by the denominator, which is gonna be 30 about, Let's add some decimals
Home tab number, desk and hemolyzed. And then we're going to say that's finally
going to give us to the present value of the annuity at the
bottom of the line, the bottom line, which is gonna be these two things
multiplied together, which are represented in
the outer column here. That's the 1500s times
the 3D 0.107 and so on. Let's add a couple of
pennies here by going to the Home tab number
a couple of pennies, we're up to 45.26161. Let's put an underline
here while we are at it. Home tab font group underlined. So there we have that
again. Now let's do it with the tables. Let's do it with the tables. So let's go ahead and
hide some cells here from K on over to P. K
to P, right-click. And let's hide those cells. Don't delete them,
just hiding them. And then we're going
to say this is gonna be the payment, payment. And this is going to
be equal to the 1500s. Now when using the tables, note the limitations
of the tables. We had to limit it
to three years to make sure that we
had 36 periods. If you go much over that, you're going to
have limitations on how many periods
are in the table. And we picked a nice even 12% because if you divide
that by 12, you get 1%. So in other words, when
you look at the table, the percents in our past
problems have been always percent per year because our periods were
a yearly period. But if you have something other than yearly periods like months, then the periods represent
months now instead of years. And you have to have the
matching percent up top, which means that if you're
given a yearly percent, if it's a small
yearly present like 2% a year than the
monthly percent. You got to divide that by 12. It's not gonna, you're
not gonna be able to use the table. We used 12%. Because if that's
a yearly percent and you divide it by 12, you can have the monthly
percent, which is 1%. In this case, we used
36 or three years, which adds up to 36 periods. Because if you use
something like five years, you're gonna be at 60 periods. And again, you're
limited to the table. So just note the
limitations of a table. Those are limitations in
a school kind of setup. If they're going to
force you to use tables in a setup
where you don't, you're not forced to use tables. You're not limited by them
because you're simply going to use a calculator or Excel
to do the calculations. So we've got the 30.108. So this will be 3.1080
adding some decimals. And we're going to say Home tab number adding
a couple of decimals. Let me double-check that. This was at 36.108130,
30.108. That's right. So then let's multiply this out. This is gonna be 1500
times the 30.108. And so there we have it. Let's say this is
from the table. This is a present value of
annuity underlining here, Home tab, font group underlying. Let's add a couple of decimals
to note the rounding. Notice that this is rounded
to three to four digits here, typically from the table. Let's go ahead and
unhide some cells now, putting our cursor on column B, dragging over to our H-Br, let go and let go. Right-click on the selected
items and then unhide. So now if I add a couple
of decimals here, Home tab numbers, we got the 45, one, sixty one, twenty six. We got that with our
running balance and then we kind of proved
it by going down to 0. And then we've got the
same thing here, the 4545, one sixty one twenty six here. And then with the table, we got the 45162 slightly different due to the
rounded a four digits. If you were to see
the actual number, it would be closer
to this that we saw when we did our
mathematical calculation. That difference is due to the
rounding from the tables.
18. Future Value Monthly Periods: Personal finance practice
problem using Excel, future value calculation,
using monthly periods. Prepare to get financially fit by practicing personal finance, we are in our Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information on the left-hand side
going to populate that into the blue area. On the right-hand side, we have the information of an
investment at 50 thousand, the rate of return
thirty-six percent, we're going to say that's
a yearly rate, the years, two years, but we're going
to be compounded monthly. So in other words,
the question is, where will we stand in
the future if we have an initial investment of the 15 thousand of the 50
thousand rate of return, 36 thousand per cent per year. And it's gonna be for two years, but we're going to be
compounding monthly. Note that the Thirty-six
percent will make more sense as to why
we chose it when we look at the limitations
of the tables when you're using that format
of calculations. So we're gonna be looking at our future value type
of calculation. There's a couple of different
ways we can do this. Sometimes this is a type of problem where
it's kinda easiest. Oftentimes to just run the
table and think about where we will be in the future as we do a running balance
type of calculations. So let's start off
with that this time. Note that we have two years. We're not going
to be compounding yearly, but rather monthly. So that means the number of periods is going to be equal to two times 12 or 24 periods. Obviously, when we
compound monthly, we have a whole
lot more periods. So when we do a running balance, it can be somewhat more tedious. But when doing it in Excel, not really a problem because
we can just copy it down, use our autofill type of calculations to do So
let's do that first. I'm going to start
with period 01, and then select
those two periods. Put our cursor on
the fill handle, drag it on down to 24 periods. And then let's center that
Home tab Alignment and center. Then we're gonna have
our initial investment which is going to be
equal to the 50 thousand. And then we'll do
our calculation with the interests or it could
just be the increase. Let's call it for
whatever type of investment that we have at
that thirty-six percent, which is probably not interests if we've got thirty-six percent, but in any case this
is gonna be equal to the 50 thousand. And then we're going to
say times the 36 per cent, but that's the yearly rate. So when we go to the monthly, we have to divide that by 12. That's gonna be the new thing that we're taking a look at. So we're at that 1500, which is our darn good
Monthly returned typically. So let's see how we can calculate that a couple
of different ways. You can take the 50 thousand, you can then multiply
it times 0.36. That would give you the
yearly return and then divide it by 12
to get that 1500. Or you can take the 0.36 divided by 12 to get the monthly
rate, which would be 3%, which is nice and even which
is the reason we chose thirty-six percent
because that 3% is something that we can
easily look up on a table, even though we're looking
at monthly rates, then you can take that and
multiply it times the 50. And that'll give you
once again that 1500. Let's do this a couple of times. This is going to be equal to the 50 thousand plus the 1500s. That's going to increase
the investment to 515. Let's do it a couple
more times and then we'll do the autofill. This is gonna be the 515
times the Thirty-six percent divided by 12. That's the new thing. And then this is going to
equal the 515 plus the 1545 gives us the 5345. Let's do a couple more times. This equals the 5345
times the 36 per cent, then divide it by two to get us the monthly percent
or monthly amount. However you want
to think about it. This equals the 53,045 plus
the 1591 given us the 546. Thirty-six, let's do
it one more time. This is gonna be equal to 54 to six Thirty-six times
that thirty-six percent divided by 12, given us the 1 sixth 39. Now we have the balance of
the 54636 plus 1 sixth 394, 56 to 75. Let's do it again. Keep it in mind
and setting it up as we go so that we
can auto fill it down, adding absolute references
when necessary. I'm going to delete
what we've done so far. Really, you're
going to delete it. I'm going to undo know. We're gonna do it again here. We're gonna, we're
gonna think about basically auto-fill When
we do at this time, this is going to be equal to the 50 thousand times
the Thirty-six percent. Now that is outside the table. So that's typically
something that we want not to move down when
we copy it down. So we're going to use
the absolute reference, which is F4 on the keyboard, or dollar sign before
the B and three, you only need a mixed reference, but an absolute one works. And then we need to
divide that by 12. The 12 is a hard-coded
or typed in number. Therefore, it'll copy
down as we go to. So then this is going
to be equal to the 50 thousand plus the 1500s. Although this is a more
complex calculation, nothing is outside the table. Both of those cells
we want to move down relative when
we copy it down. Therefore, no absolute
references necessary here. We're then going to
select those two cells, put our cursor on
the fill handle, left-click on it and drag
it on down 24 periods to get to the 101640 about. There's that. Let's do it again.
Let's do it this time. Let's do it with the future
value calculation in terms of an Excel worksheet
formula or function. This is probably the
two ways that we would do this most
commonly in practice. And then we'll move
on to the table and the mathematical formula. Two ways that you
might do this in a school typesetting
more likely. Let's go ahead and
hide some cells first, I'm going to put my cursor on C, even though it's really
skinny over here. And then scroll on over to F. Let go, right-click
the selected area and hide those items. And then we'll do our
calculation here. I'm going to do it
more quickly than in the past because we've
seen these in the past, but I'll kind of
emphasize the new areas. So I'm going to say negative
future value shifts nine. This is all the same, but
then the rate is that 36% and we got to divide that by 12 because we're looking
for the monthly rate. So divided by 12,
that's the new thing. Comma number of periods would be two years if
compounded yearly, but now 242 times 12, which we already have down here. So I'm just going to
pick up the 24 comma. This is not an annuity, so we don't have
a payment commas that brings us to
the present value, which is at the 50
thousand and enter. So there's our one-to-one
six forty. Again. We can also, of course
do that with the tables. So we can say that
we have the tables, which is the payment, let's say, which is gonna be
the 50 thousand. When we look at the tables, then we're not looking at the periods no longer
represent years to us. They have to represent months. And the percentages need to
represent them to relate it. Monthly percents, not yearly presents were given
the yearly percent. So we'd have to take
that and divide by 12. So if we take 36 divided by 12, we would get three. So the monthly percent is three, which you can see why we're
chose that percent if we're working on a
book problem where we're forced to use tables. Because if I use
a percent that's uneven or less than one, then we're going to have a
problem with the tables. So remember, if
you're in a school setting where they're going
to force you to use tables, they will often be limited
in these ways and you can kinda keep that in mind as you're working
through the problems. So we got three and then we're also limited to the
number of periods. That table only goes
down to 50 periods. So we've got two years here, which in months would be 24, which is still
pretty far down on the table even though
it's only two years, so 24 and then three on the percent is going
to give us that too. 03282.03282.03 to eight,
adding some decimals, Home tab number group a couple of decimals
or four of them. This is the amount
from the table underlining that Home tab, font group and underline. And that's gonna
give us then our MT, which we'll call future value. Let's say this equals to 50
times that 2.03284101640. Let's add a couple of
pennies Home tab number, a couple of pennies, even there. Now, let's do it again
this time with the, with the mathematical formula pointing out the
differences here. If we were to do a
mathematical formulas such as this for
the future value, let's hide a few cells. Hiding this cell I can't
see what it is but that skinny sell on over to, I let go and right-click
and we'll do this again. Don't delete it,
hide it, Hide it. And then we've got
the future value equals the present value, which would be the 50 thousand
times one plus the rate. The rate would be the
Thirty-six divided by 12 or three to the
number of periods, which would be two
years times 12 or 24. Those would be the
major changes as you plug it into your
algebraic equation, which we will do in the format
matt of a table of top. We're going to save. We'll start off with
the present value in a similar way as we've seen with prior presentations
at the 50 thousand. And then we're going
to say that we have these sub calculation, which is going to
be the one plus the rate to the n periods
that we're going to pull that into the
inside, which is one. The rate is going to
be equal to the 36th, but we got to divide that by 12. This is the new thing. That's the new thing here. Home tab number per cent define that gives us a nice even three, which is not likely to happen. Oftentimes when you're
really doing that in real life because you won't
have a nice even present. But we're going to
go to the Home tab, font group and underlying. Let's give us subtotal here, which is going to be oral. Just call it one plus the rate, which is our subtotal,
equals the SUM, sum of those two numbers, making that a percent
Home tab numbers, we could add a
couple of decimals, 1.03, or make it a percent
103 per cent when we do. And that will then be
taken to the number of n periods and periods, periods. So this is going to
be not two years but 24 periods because we
have monthly periods now, that's one of the new things. Home tab, font group
and underline. And then that's
going to give us, we'll call it the one
plus the rate shift to the ships six periods
of n periods. And we'll put that
into the outside. This equals the 103 per
cent shift six carrot to 24 periods. Adding a couple of
decimals Home tab numbers. Deaths in a more
lies in that cell. Fonts group underline. And that'll give us
our future value. Let's call it the future value. Future value, which is going
to be equal then to the 50 thousand times the 2.032
and so on gives us our 1011, 40, adding a couple
of decimals there, Home tab number group
coupled decimals, and make it a little wider so it can handle the decimals
that are added. There we go. Let's do some indentations
selected in these cells. And let's indent them
alignment and indent, alignment group indent, and then alignment,
droop and indent. Okay, so now let's unhide some cells putting
our cursor from B to K so we can see what
we've done thus far. Btk, let go,
right-click and unhide. So now we had our, we had a running balance
getting us to the 101640. We had our 101640 with
our Excel formula, which we can add a couple
of pennies to if we want. Number group, a
couple of pennies, one-on-one, six
thirty-nine, seventy one. And then we got 101640 on the tables due to
rounding from the tables. And then we've got the
101, six, thirty, nine, seventy one also with the Excel, with the mathematical formula. I'm going to delete this up top. And this number right here from the tables is rounded
to four digits. You can see it matching
up to this number here, which is actually longer
than four digits, which is the result or the cause of the
slight difference. Here for rounding.
19. Future Value Annuity Monthly Periods: Personal finance practice
problem using Excel, future value of an annuity calculation
using monthly periods. Prepare to get
financially fit by a Practicing Personal Finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information
on the left-hand side, I'm going to populate
that into the blue area. On the right-hand side, we have a savings
type of scenario. We're going to imagine
we're going to invest each month One thousand dollars, not per year, but per month. We're gonna do it for 1.5
years on a monthly basis. The rate of return
is gonna be the 12%. We're assuming that's
the yearly rate. So when we think about the
monthly component for it, we'll have to break it
down to a monthly rate, which would be the 12% divided
by 12 or one per cent. So first let's think about the number of periods that
will be covered here. If we're going to talk
about 1.5 years, 1.5 years, we're going to take
that 1.5 times 12, that would give us 18 months. So the number of periods we have in months will be 18 months. We're going to put in 1
thousand per month over that 18 month or 1.5 years
at the yearly rate of 12%, which would be a monthly
rate of one per cent. Let's first think about
that with a table that's going to be the starting point with this type of investment, which I think is most
intuitive to think about. So I'm going to say
this is gonna be from period 12 and so on. Notice I'm starting at
period one instead of at period 0 because we're
looking at an annuity here. And typically the annuity is calculated at the
end of the period. So we'll start at the
end of the first period. Selecting those two items. I'm going to drag that on
down to our 18 periods. Obviously, this running
balance calculation table is longer when we're talking about monthly period instead of a yearly
kinda calculation. But with Excel, easy to do, we can just drag it on
down, not a problem. We're going to center
that by going to the Alignment Group and center. There we have it now
this might be interests, I'm just going to
call it an increase. Because it could be
interests are it depends on the investment
that we are in as to the format of the gains or whatnot that
we will be getting from it. And we're going to
say that the payment will be $1 thousand. So that's gonna be the
payment that we're putting in to the investment. We're going to say that happens
at the end of the year, therefore, no interests
accruing on that first payment. So that's gonna be simply
our starting point at that $1 thousand
than a year later, we're going to have what
are increase would be, which will be interest
or dividends, or basically gains if we're
in stocks and whatnot. And we're going to assume
that that's at the 12% gain, which is the yearly rate. But we're talking about
months, in this case. 1 thousand times the
12% that would be per year divided by 12 to
get the monthly amount, which will be around ten. Now if we thought about that
in the trusty calculator, you could do it a couple
of different ways. Normally, I would do
it like this if I had a calculator and I had
to do it by hand, right? 1 thousand times the 0.12, the yearly rate would give us the interest if it
were for a year, 120 for a year, but it's per month. So I got to take that
and divide it by 12. So we get the ten. Or you can think
about it this way, which is kind of the way
you need to think about it when you're looking
at Excel functions, which would be the yearly rate, 0.12 divided by 12 for
the monthly rate of 1%, then times the 1 thousand. And that would give us our ten. Notice that that
rate that we used, the yearly rate of
the 12% is nice. And even so we can
divide it by 12 and get the monthly rate of one. That's not always the case when you're doing that process. But for book problems
that could be necessary if you're gonna be
using things like tables, having ugly-looking numbers
that are below 0 and or nice or not nice even
numbers is not a problem. You're doing this in Excel. Okay, So then the
next payment is going to be the payment of 1 thousand. And now we're going to say that and let's make the payment. Well, then we're going to
say this will equal the 1 thousand plus the SUM shift nine left arrow
holding down shift left, again, closing up the brackets. So that would give us
the 1 thousand plus the 1 thousand plus the
ten or the 2010. Let's do it a few
more times and then we'll do the autofill
to copy it down, we'll do it then the easy way. In other words, let's go
ahead and say this is going to be the
2010 times the 12%. We're gonna take that
and divide it by 12. And that'll give us
tab Twenty about. And then we're going to
say the payment is gonna be the same 1 thousand that we're putting in every
month on a monthly basis. This is gonna be the prior
amount plus the SUM or some shift nine left arrow
holding down shift left again, closing it up, shift 0, Enter. So the 2010 plus 224,013. Then we're going to calculate
the 3,030 times the 12% then divided by 12 that
I'm going to select tab. And the payment will once
again be 1 thousand. So our new balance is
going to be the 3,030 plus the SUM some shift nine left arrow holding
down shift left again. Plus the 1 thousand
and the third, closing up the brackets
gives us 4,060. Let's do it one more
time and then we'll go back and do it the easy way. This is the 4,060 times
the 12% divided by 12. I'm going to select tab. Payment is going to be
equal to 1 thousand tab. This is gonna be the
prior 4,060 plus the SUM, some shift nine brackets
of the 1000s and the 40, closing up the brackets. And there we are at the 500101. Now we're gonna go
back and do it again, but thinking about
how we can auto fill so we can do
it the easy way. So we're going to
select these cells, delete them, I'm
going to delete them and start all over again, but that's okay because
this time, the easy way, this is gonna be the 1
thousand times the 12. And that 12 is
outside the table. So I'm going to
make it absolute by selecting F4 on the keyboard. Then I'm gonna
divide this by 12. That 12 is hard-coded or
typed in, and therefore, it will be copied down as
we copy the cell down, no need to do
anything special to it for that to be the case. Then we're going to say this
equals the one thousand. One thousand needs to be the same cell
when I copy it down. So we're gonna make
it an absolute reference selecting F4 and the keyboard dollar sign
before the B and the three. Then we're going to
say this is gonna be equal to the one above it plus the SUM some shift nine, the ones to the left and
close up the brackets. Although this is a
more complex formula, everything's in the table. Everything should move down relative when we copy it down. Nothing special needed,
no absolute references. Therefore, now let's go ahead and select
those three cells. Use our autofill
handle, clicking on it, dragging it on down
to 18 periods. And at the end of the day, at the end of the time frame, we get the 19615 about. That's gonna be
our ending result. Let's calculate it
again this time using the future value of an
annuity calculation in Excel, the function, these
two components are probably the things that would be most useful in practice. Then we'll move to the mathematical formula
and the tables, things you might often see in a school setting more likely. Let's go ahead and
hide some cells. Putting our cursor on column C, dragging over to column G, C to G, right-click those
cells and hide them. Then we're gonna do
our calculation here. I'll do it a little
bit more quickly because we've seen
it in the past, pointed out the new
things that will be here. This is going to be
negative to flip the sign future
value shifts nine. The rate is gonna be that 12%, but that's a yearly rate. So we've got to
divide that by 12. That's the new thing. That's the new thing
we're doing here. Then comma number of periods would be years
if it were yearly. But no now is to 1.5 years times 12 or 18, which we already have. So I'm gonna be picking up
the 1800s instead of the 1.5 years to 18 months
comma payment, payment is going to
be the 1 thousand, which is pretty straightforward
as long as we make sure that we know that that's
the payment per period, which in this case is per month. Okay. And then we're
going to say Enter, we get that 19614. Let's add a couple
of pennies this time Home tab Alignment, couple of pennies
on the decimals. 1960s, 14, $0.75. Now let's, let's do
it the mathematical formula way and we'll point out the differences
that happened here, which will be with the
rate in the periods again. So let's put our
cursor on column. I think that's h. I can't see it too well because
it's kinda, it's hidden. But that's skinny column. We're gonna go to that
one on over to j. Let go right-click and hide those cells were looking
at the formula down below, which is the future value
of an annuity calculation, which is calculated as
P times one plus r. R being the rate, not the 12%, but 12 divided by 12, which would be 1% to the
number of periods, n, which is not gonna be 1.5 years, but rather 18 months, which is 1.5 times 12. Those are the new
things, minus one divided by the rate, once again, being not 12, but
12 divided by 12, which would be 1%
the monthly rate. Okay, so let's do it. Let's do it then. Let's do it in our table format. We'll do the table format. So on the outer column
we've got the 1 thousand. Then we've got the numerator. The numerator, which
is going to be then one plus the rate. So we're right here
at the rate now the rate is going to
be equal to the 12%, but we're dividing it by
12 for the monthly rate, making that a percent Home
tab number group per cent, define it 1%, font
group and underline. Then we'll get the
subtotals sub TO tau, which will equal the
sum of shift up, arrow holding down, shift
up again and enter. Let's make that 8% as well. By going to the
Home tab numbers, you can add some decimals, 1.01 or make it a percent, which would be 101%. Then we'll take that
to the number of periods we're right
here in the formula. So we're going to take
that to the number. Of periods, which we can say
is called N in our formula. And that n is represented by the 1800s, which is in months. So it's not 1.5 years, but 1.5 times 12 or 18. And we're then
going to underline that Home tab font
group and underline. And that'll give us, let's call it another subtotal, subtotal. And this is gonna be equal to the 101% shift six
to the carrot of 18, enter, adding some decimals to that so we can
see what's going on in their home tab
number group desk and a mobilizing it? Yes, In a mobilized. Then we're going to say less. One, One, One right here. We're right there on the
numerator still one. Underlining that by going to the Home tab fonts
group and underline. And then finally, we'll bring that out to
the outer column and we'll call that
the numerate, tore. Numerate, tore numerator. I can't. Okay, here we go. This is going to be equal to
this number minus the one. Adding some decimals,
Home tab number, group deaths and normalized. So there we have that. Let's do some indentations here. Let's select these. These items. Go to the Home tab
Alignment, indent this item. Home tab Alignment in dance. So there we have that. And then we just need
the denominator, which is the rate denominator. I typed it better that time. Well, it's faster. I'm
not even sure if it's spelled if I spelled it
wrong and I apologize, but the rate is gonna be
the 12% divided by 12. That's the new thing
because we need the monthly rate,
not the yearly rate. Home tab number group
and percent of phi, that font group underline it, and then we'll add it and make it another subtotal, subtotal. Bringing that to
the outer column, that's gonna be this
whole thing that we finally got done calculating, which is going to be equal to the numerator divided
by the denominator, making that a desk cannibalized
number, adding decimals, Home tab numbers,
deaths in the Molas, and then font group
and underline. And that's gonna give
us our future value of an annuity calculation. Finally, just multiplying
this outer column out, which is going to be equal to the 1 thousand times that desk normalized number we came to. Let's add a couple
of pennies here. Adding pennies Home
tab number group, a couple of pennies, 19, 14.75. About let's, let's
do it one more time, this time with tables. So I'm going to hide
sum from k to o. Now put our cursor
on the column K, the skinny column there, and then go on over to o. Let go right-click and
hide from the table. We're going to have the payment. This is what she might do
in a classroom setting. Payments. And the payment is going
to be the 1 thousand. Then we just find the
amount from the table, noting that you've got
to have the right table. This is an annuity table
that we're looking at. So we've got the future
value of the annuity. And then we got
noticed in the past the periods and the rates represent yearly
rates and years. Now they represent months. So that means we
have 18 months here. And then the percent isn't 12%, but 12 divided by 12 or 1%. And you can see why we
picked 12 as the percent, because 1% is on the table
and uneven percent would not be on the table and
anything below 1% would not. Therefore, if I chose a yearly percent of
anything under 12, wouldn't be on the table and
anything that's not evenly divisible by 12 wouldn't
be on the table. So that could be
useful to know in a school setting if they're
going to be using the tables. So we're going to
say we got 118 than one in 18 brings us
to the 19.61519.615. That's from the table. Let's add some decimals
to the Home tab numbers. Animals, make an underlying
font group and underline, and that's gonna give us our
future value of an annuity, multiplying this out 1
thousand times the 19.61. And we're going to
add a couple of decimals Home tab number group coupled decimals
worth the 1960s, 15. Let's unhide some cells and
just recap what we have done. Putting our cursor on column B, dragging on over to column Q, right-clicking on it and unhide. So now we did this with
a running balance, getting us to about 19615. We did this with the
annuity formula function within Excel 1961475, got to that same
more exact number, more exact in the
tables at least of the 1840s and 75 here. And then on the tables
we got to the 19615, slightly different
due to rounding, noting that this
amount here from the tables rounded to
three to four digits, whereas the actual
number we can see from the mathematical formula is
not rounded to four digits, but continues on resulting
in that rounding difference.
20. Annuity Due Present Value: Personal finance practice
problem using Excel, annuity due present
value calculation. Prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Now we're down here
in the practice tab as opposed to the example tab. The example tab in essence being an answer key information on the left-hand side going
to populate that into the blue area on the
right-hand side, comparing and contrasting
annuity calculations for a standard annuity
present value of a normal annuity versus the present value
of an annuity due, or in other words, an annuity where the payments
happen at the beginning of the period as opposed
to the end of the period. In other words, normally when we just think about an
annuity by default, the payments we're assuming are happening at the end
of the time period. And we can then choose to have the payments happen
at the beginning. But of course that will
affect the end result. The easiest way to
start looking at that is to see the
Excel functions, in my opinion, to see what
those differences are. Then we'll kinda solidify
what is actually happening in our mind by doing a
running balance calculation. And we'll try to verify the
future value calculation. So we can kind of go back and forth from present
and future value, which might give us a better
understanding as well. Let's start off
with the standard annuity calculation in Excel. So we've seen this in the past. I'll do it fairly quickly. Negative present
value so that we can flip the sign shift nine. And we're going to then say that this is going to be
equal to the rate. The five per cent
were on the rate. And then comma, the number of
periods is going to be six. And then comma the payment
because this is an annuity, we use the payment
of the 1 thousand. Now normally that's where we
stop and we just know that the default will then be a
normal annuity typically, which will have the
payment at the end. And we can say Enter,
we get the 5,076 about. But note that if I
double-click on this, you see that we still
have these two kinds of arguments down here below
that we could go to. Now normally these
two arguments are the differences between an
annuity and a non annuity. So this time we used an annuity, therefore had the payment as opposed to having two commas, not using the payment and
having the future value. But I can have another comma. It will then take us
to the future value. We're not going to
use the future value, but I might want to
get over here to this, to the type argument. So comma again will take
us to the type argument, which by default they
have as a normal annuity. Now, we could choose
the number one here, and that would change it to
basically an annuity due. So if we want it by default, have that 0 up top,
it won't change. The bottom-line number is
just gonna be the same thing. If I choose one, then it will change the
default settings. So if I keep that
there were still at the normal kind of
annuity even though we extended the formula to
include the type explicitly. Now here let's do that
and then we'll change the type to the
beginning of the period. So same starting point, negative, present
value shifts nine. Rate is gonna be the 5% comma number of periods
is now going to be six. Same thing, comma number. And then the payment is once again going
to be 1 thousand. And then I'm going
to try to get over that type field again. So I'm going to
add another comma. And now the future value, we don't have a future
value because it's not an annuity calculations. So another comma,
and now we have the type which I'm going to choose beginning
of the period, which is indicated by a one. You can double-click on
it or type in a one. And we get to a
different result, which is going to be that
5,329 as opposed to the 5,076. Now, to kind of solidify this in our mind we can do are
running balanced type of calculation starting
at the end result and working it back to see
what is going on here. Sometimes it's a
little bit easier with this particular calculation
to kinda think about it. Well, because if we have the 1000-dollar
payments at the 5%, sometimes it's easier to
actually projected out to the future value and then
present value it back. Sometimes that clicks
more in people's minds. So let's just see what
that would look like. For example, if I
thought about this as a future value
calculation at the 5% and then I brought it back
to the current time period. We'll get to the
same end result. So for example, I'm gonna make this a future
value annuity, the same time series of
payments, same rate. But now I'm going
forward in time. We're going to end up
at a 0.6 years out. And then we're going
to have to bring that point back to the present to get to the
current present value. So for example, it
would look like this negative future value. Shift nine. The rate would be the 5% comma, number of periods would
be six periods comma. And then the annuity, we're going to pick
the 1 thousand. We have the same kind of thing. I could go to the type
here and make it a 0, but it's already
there by default, if I leave it as is, so I'm going to say, okay, that would then be
the future value. So that would be. Series of payments as
if they were earning 5% and that's where we would
be six years in the future. Now I can, I can say, okay, well what if I took
that future value 60 years out and I use
a present value of one, taking that single amount
back to time period 0, discounting it at the 5% that should give us to the same
result that we got to up here. So let's try that. That's gonna be negative. Present value shifts, nine rate, five per cent, comma, number of periods is going
to be six comma and then no payment because now we're
going to use present value of one for that one number comma, and then up once to
that future value we just calculated and Enter, and that'll give us to
that, to that 5,076. Now sometimes the reason
that's kinda easier to see sometimes is because when you do the running balance
for an annuity, it's kinda easier to
build the table of going forward to get to the
future value of that 600802 to kind of verify it in your mind and then bring it back using the present value
calculation here. Of course, you could
do the same thing for like an annuity due. I can do annuity due going
forward into the future, which would look
like this negative future value shift nine, the rate 5% comma, number of periods
would be six comma, the payment would be
1 thousand comma. And then I'm going
to try to get over that type field again. So I'm going to
say comma, again, bringing us to the type. And this time I'm going
to choose the one to make it at the beginning
of the period and Enter. So now we're at the
7,142 if we were to visualize it going out
six years into the future. And then if I simply
present value that back to the
current time period, six years back, we should
get to this 5 thousand 329, which we could do by saying
negative present value shift nine rate is going
to be the 5% comma, number of periods is
going to be six comma, comma because this
is not an annuity. Future value would be that
number we just got to. And then that would bring
us back to the 5,329. So again, that could
give you some idea too. And then you can kinda
do you're running balance tables to come
up to these numbers, which, which could solidify
how this whole thing works. We're going to now
try to recalculate, use these numbers to
verify what we have done. So let's go over here
and think about are running balance for a
normal kind of annuity. I'm going to start at 012. Select those three numbers. Autofill on down. We're gonna go to the Home tab, the alignment and center. And I'm going to
start at the balance, which is the end result here of our normal annuity,
which was a 5,076. And then try to prove this by basically going
through a series of payments in ending up at 0
at the end of this process. So in other words, we're going
to say that the increase here would be equal to the 5,076 times the 5%. The payment is
gonna be that even 1 thousand each time, each time. And I'm just going
to copy this down. So I'm going to
double-click on this one. That 5% is outside. We're gonna, we're
gonna make it an absolute reference
selecting F4 on the keyboard dollar
sign before the B and to this payment is outside. So I'm going to make it
absolute by selecting F4 dollar sign before
the B and one. And then I'm going
to add this up. This is the prior
balance to 5,076 plus the sum of
these two numbers. This one being a negative means that when I
sum them together, which usually means adding, it means it's going to
subtract it because I'm adding a negative number,
closing the brackets. There we have it. So
the 5,076 plus the 254, about minus 21 thousand, brings us down to 4,329. Obviously the inquiry
we're getting, the gain that we're getting is less than the payment
that's going out. If we continue this process, we would assume then at
the end of the six years, we would be down to
0 at that point. So let's select these three. Use our autofill by putting
our cursor on the fill handle and dragging
that on down. And we get, We get to 0 at
the bottom line number. That should verify because
you can say, Okay, if I had a series of
payments for $1 thousand, that's going to be
equivalent to the 5,765 if the rate was
5% for six years. Because if I was to take out One thousand dollars for
each of that time period for 6 thousand over the
six years after that 5% rate over
that time period, I would end up with
a net result of 0, even though I took out
basically the 6 thousand over the six-year time period and
started with an amount of only the 5,776 about. Now, if we did this one, it's a little bit more of a complex calculation
here to do that. So I got a little bit
more complex of a table. So we'll start here with 012. We're going to
auto-fill that down, dragging on down, auto-fill
that down to the bottom. We're going to go
to the Home tab Alignment and center that. And we'll say that this balance. Starts at the at the 5329. And then what we're going
to say is the payment happens at the
beginning of each year. So I'm going to say
negative of the 1 thousand. I'm going to select F4 on the keyboard because I'm
going to copy that down. So there's our
negative 1 thousand. So the beginning balance at the beginning
January of year one, we can say January 1st of
year one would be that 5329 plus the 1 thousand
or in other words, plus a negative number
or minus that number, bringing it down to 4,329, which will result in
our increase being less because now we're saying it's happening from January, december, given us an ending
balance that we're assuming we'll be getting the interests on or whatever our gain is. So that's gonna be the 4,329. Plus. Then we'll, we'll
hold on a sec forth. That's 321 times the 5, 5% percent up top. Once again, I'm going to select F4 on the keyboard to make that absolute. So
there we have that. So now the interest is going
to be less in year one here, because, because we said that the payment happened
in the front end. So then if we were
to add this up, we would have an ending balance. This would be the
ending balance, the sum of the beginning
balance plus that increase. So now we're at the 4,546
and this is gonna be, let's call it the
ending balance. So then we can copy that down. If I was to copy this down
and auto fill that down, we then should get down to 0 at the bottom line once again. So we were at this point
at the end of year one, and then at the beginning
January 1st of year two, we got the other 1
thousand coming out. That means our
beginning balance in January 1st of year two is to 4,546 minus 21
thousand or 3004546. Then there's an
increase on that for the year of year to
January through December, which is that number
times the percent of 5%. And then we can
add those two up. That's gonna be then
our ending balance at the beginning
plus the increase. And then at the
beginning of year three, we're going to say that
the $1000 went out. So that means that at the
beginning of year three, we have this 3,723 minus
the 1 thousand or 2723, which we're going to
multiply times the 5% and then add those two together to
get the ending balance. And then at the
beginning of year four, we took out another 1 thousand. And so that means the
beginning balances that to nine are the 2859
minus 21 thousand times the 5% was it five per cent is gonna give
us 93 ending balances, the adding of those two. And then at the
beginning of your five, we took out another 1 thousand. And that means our
balanced went down to 952 at the beginning
of the year. We earned 45 during the year. And then if we add
those two together, we got the 1 thousand left. And at the beginning of
your six, we take that out. And that means we're, we're down to 0 and we're
not going to get any benefit in the year six because of course the balance is now down and we're not gonna, we're not gonna get
any income in on it.
21. Present Value of Annuity using Non Annuity Excel Functions: Personal finance practice
problem using Excel, present value of an annuity. Using non annuity,
Excel functions prepare to get financially fit by practicing personal finance. We are in our Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab in essence being an answer key information on the left-hand side
going to populate that into the blue area on the right hand side will be
looking at the present value of an annuity due and the normal kind of annuity
type of calculation. Then also breaking it
out into its components, into its individual periods, in this case years. And applying the
present value of one calculation on a
year-by-year basis. Something that you might
say, why would I do that? That's somewhat tedious, but it's fairly easy
to do in Excel. And it's actually quite common, even if you have a nice
annuity kind of set up, because then you
get the more detail on a year-by-year basis. And also when you're looking at a more complex cash
flows situation that you can't break out into
a nice standard annuity, then this is the method that
you basically have to use. This is often a common
method when we think about the present value of
an annuity just to keep us scenario in your mind is
if you're budgeting going forward into multiple periods into the future and you're
trying to think about, should I do one path or another? For example, should I purchased a new piece of equipment
or something like that? And you're trying
to project into the future what
that would result in terms of cashflow streams
or returns into the future, that kind of
decision-making process. So here's going to
be our information. We've got the amount
is going to be $100. We got the rate 7%. The years at five years, we're just going to do this with the Excel functions this time. So we're not going to be using a mathematical calculation and we're not going to
be using the tables. We're going to do what we
normally do in practice here, which is going to be
an Excel function. And then we'll add
some more detailed, possibly with a running
balance when applicable. So first we'll just do
the normal calculation. We'll do it fairly
quickly because we've seen this in the past. The normal annuity calculation, I'm going to say negative to
flip the sign present value, shift nine, the rate is
going to be that 7%. I'm going to say comma, we're going to pick up
the number of periods, which is going to be
five periods down here, and then comma, and
then it is an annuity. So we're gonna be using
the payment item. That payment we're going
to say is 1 thousand, We present value that
we're at the 4,500. Obviously, if we were to
add up all the payments, the total cash flow. So cash flow without the
present value would simply be equal to the 1 thousand times
five versus the 5 thousand. Let's go ahead and make
this one black and white. And let's go ahead
and make this one. This one will already be there
on your Excel worksheet. Okay, so then we
might say, well, let's break this out into a one-by-one Present
Value of 15 times. And so this hopefully
will give you an idea of the interplay between
these two things as well. But the present value of one and the present
value of an annuity. Also note and be aware of how we're setting
up the table here. Because how you set up
the table will make these calculations much
easier and allow you to do projections
and more complex and nuanced to projections a
lot more easily as well. So we're going to set this up by putting our years over here. I'm gonna say 12. Selecting those two, going to put our cursor
on the fill handle, drag it on down to five periods, or five periods is
due five periods. And we'll center that Home
tab, Alignment and center. Then the payment is simply
gonna be $1000 each period. So I'm gonna say this
equals $1 thousand. So there we have it. I'm going to say,
we could say F4 on the keyboard expecting that we're going to be
copying that down, putting a dollar sign
before the B and three, in other words, making it
an absolute reference. And then what we'll do is, let's copy that down first. Here's our series of payments. Let's copy that down. So there's our five
payments of 1 thousand. If we total this up, we can put up the total here. This is going to
be the sum equals the trustee equals SUM, shift up, arrow holding down, Shift Up, up, up, up, and enter. So now what we'll do is we'll
just present value of one, not an annuity we have on our annuity setup in
our years set up. And we'll just do
a present value of one calculation on an
individual by individual basis, which is something
that we can copy down. So you can see this is
fairly easy to set up once you have the table
properly put together. We're going to say this is
a negative present value, shift nine, the rate is
going to be that 7%. Now we will do this
a couple times, but if you were to copy it down, you'd say F4 on the keyboard so that you have an
absolute reference there. So that you can
copy that down and the 7% doesn't move down. Comma, we'd have the
number of periods. Now here's where the number
of periods is now one, not five, because we're
doing this one at a time. So we're trying to
take the one payment that's gonna be one year out, bring it back to 0. And I'm going to pick that
one up not by typing it in, but having it over here in
our formula or in our table. And note how convenient that is. Because by not typing it
in and using the table, I can then copy this down and this cell will copy
down relatively. So I don't have to deal with reformatting it all the time. And again, that
makes your table way easier to be copying down. So we'll say comma
and then comma again because this
is not an annuity. Now we're doing the
present value of one, and we'll simply point
to that 1 thousand. And there we have it. So
the one payment that's one year out is if I bring it back to time period 0 would be 935 about. Let's do it again. We'll just do it a couple more times and then we'll
go back up and copy it on down using
the autofill feature, negative present
value, shift nine, the rate is going to be
that seven per cent. We're going to say comma, number of periods is
going to be this two, which we're not hard
coding or typing, but rather getting
from our table. And notice how nice it is that
I can then copy that down comma and then comma
because this is not an annuity but
present value of one, we're basically taking
this $1 thousand, discounting it back
two periods to period 0 using the discount rate of 7%. Let's do it again, negative
present value, shift nine, we're going to pick
up the rate 7% comma. We'll take the number of
periods, which is now three, which I'm going to
pick up from this cell instead of hard-coding
or typing it comma no payment because this is not an annuity
comma future value, One thousand again and enter. So we discounted this $1000.3 years out that
we're expecting to get it back three years using
the discount rate of 7%. Obviously, you're
getting a present value, which you get a decrease as we go further out into the future, expecting the
cashflows happening further out in the future, which is what you would expect. And also something
that gives you a better visual or concept or idea of what's
actually happening. Then you get, when
you just kinda get the magic number here
for five years out. So this can give you a lot
more contexts and again, easy to do really in Excel. So now we're going to say
Do it again, Present Value, Shift Nine is going to be, then the rate is going to
be the 7% comma number of periods four comma and then comma future value,
one thousandths. Do we discounted that
1 thousand back for years now at the
7% to get the 763, let's go ahead and
delete these and do it one more time
this time with the autofill just to see how easy it is to auto-fill it down. So we'll say negative
present value. Shift nine rate is that 7%? I'm going to make sure to hit F4 on the keyboard this time, making it absolute dollar
sign before the B and four. That means it's not going to
move when I copy it down. Comma number of periods
is gonna be that one. This one, I do want to copy it down and that's
why I structured the table to have the years
in a column format like this in if cell reference that I can easily reference just the year. If I put something like
year one in this cell, I can't reference it because
it's not a number anymore. But if I put a one there, I can reference this
and copy it down. Then comma, comma future
values that 1 thousand. We want that to move
down as we copy it down. So we're gonna say, okay, and then we're just going to
do our auto-fill feature, putting our cursor
on the autofill, dragging it on down. I'll double-check
the last one by double-clicking on it to see if it does indeed do what we want. The rapes pick it up at the 7%. We've got the payment, which is picking up here, and we've got, we've
got the future value. This is the number of
periods picking up here. Future value, it looks like
it's doing what we want now we can just
simply sum it up, equals the SUM UP, holding down, Shift Up, up, up, up and enter. That's gonna give us our
4,100 matching out here. Let's put an underlying just to make it look a
little nicer font, group and underlined.
So there we have it. Like I said before
you had Excel, you would try to avoid this kind of calculation
whenever possible. And when you're working
with book problems, you're going to avoid
it because calculating five separate present value
calculations is tedious. And you don't wanna do it. But if you're using Excel, you can see how easy
it is to do and how much more flexibility
you have to do that. And it actually gives you, even with a normal common
calculation for an annuity, it gives you more detail that you're going to want to have. So it's often useful to do that even in a standard annuity. And when you have more
complex cashflows, if you're doing something and making projections
into the future that you're going to have
uneven cash flows in some way, then you basically have to do this if you're trying
to project or budget into the future and you're imagining what would
happen if my revenue goes up by 5% each year
or something like that? Well now you've got
an uneven cash flow into the future and whatnot
if you're going to present value that and try
to compare it to some other option where
you think revenue is going to grow
differently but for a longer time frame and
that kind of thing. So we can also set
this table up to, I like to see it this way. That's how I tend to set it up. But a lot of times when you
do budgets and whatnot, you'll end up with a budget on this kind of horizontal fashion. And then you can use your, use your present
value table function in this format as well. So in other words,
let's hide this. Sales and look at that,
we're going to put our cursor on column C, drag on over to column I. Let go, right-click the
selected area and high, don't delete it, just hide it. And then we're gonna,
we're gonna do this again. This time we'll just
do the same thing, but now the years
are on top here. So we've got our
years broken out. And the reason this
is helpful is if you do like an income statement, you'd have income
and expenses that list out here by year possibly. And then you can have
a complex series of cash flows for inflows and outflows for an
income statement. And then you can get your
bottom-line cash flow. And then you can
simply apply out your present value to try to discount everything back to the current time period using
your discount rate here. So let's try that out. So we're going to, we're
going to say the payments. This is gonna be
the payments now, just gonna be that 1 thousand. So this is going to be
equal to the 1 thousand. I'm gonna say F4
on the keyboard to put a dollar sign
before the B and three. And then we can just
add that across. We can say, let's bring those payments across
with a five payments. That of course, adds up
to the 5 thousand that we're expecting to
happen in our annuity. Let's do the trustee SUM to
say there's our 5 thousand, then we can have our
present value calculations. Same kind of concept, except now we just
got a little bit different format of a table. So it's useful to see, to be able to see these
tapes In your mind, to start to build them. What do I want? Do I want, do I want them the x
and y-axis and whatnot? Now, the better you
can visualize those that easier it makes
things, it's basic stuff. It's nothing, nothing difficult, but it is difficult in that
until you start visualizing. It's kinda hard to see how you
want to set your table up. So in any case, this is gonna be the present value shift night. Let's make it a negative
present value, shift nine. The rate is gonna be that 7%. Once again, we can make an F4 or absolute reference
to copy it across. Although we will first do
this a couple of times before we do copy it across
comma number of periods. Now there up top
here, one period out. So we've got one period out. Notice that we do have each of these headings as
just one number, because if there's anything
other than a number in it, I can't reference to it. I have to hard
code the number in my formula and then it
doesn't copy across easily. So just be aware of that makes the table a lot easier
if you can copy it across and then comma and
comma future value is gonna be that 1 thousand
right above there and enter. So there we have it. Let's do it a couple more times. Negative present
value, shift nine, rate 7% comma, number
of periods is now two, which I'm picking up from
the table up top comma, comma because it's
not an annuity, but present value of one, future value is the 1 thousand. So we discounted back that
1 thousand now two years at the discount rate 7%
through it one more time. And then we'll do the
autofill negative present value shift nine rate is gonna be that 7% comma
number of periods is now three, which I'm picking up
from the top column of the table, comma, comma because it's
not an annuity but present value of one. Picking up the future value, which is the 1
thousand and Enter. So on. Let's go ahead and then do
this for the whole thing here. Let's delete these and
do it one more time. Being mindful of what we need
to do to copy it across, including things like
absolute references. So we'll say negative
present value shifts nine, rate 7%, that's
outside the table. So I'm going to make
an absolute reference by selecting F4
and the keyboard, putting a dollar sign
before the B and four, you only need a mixed
reference, by the way, but an absolute references
easier to think about. Comma, number of periods
is now that one. I don't need an absolute
reference here because I want that to move
to the right as we copy the cells
to the right comma it's not a payment because
it's not an annuity comma. The future value is
the one above it. I don't want an
absolute reference here either because I'm going
to copy it across. Also note that if this
was a basic table, you might just get this number from the reference to the right, which is the 1000s, and make it absolute. But if you've got a more
complex series of payments, then of course you'd
want the payments will be listed up top. So it's more common
to this format. And then we're going
to copy it across, put our cursor on the
autofill handle and drag it on down, drag it on down to five periods. Then we can sum this up equals
the SUM of these items. And there we have that 4,100. Once again, Let's
unhide some cells. We're gonna go put our
cursor on column B, drag on over to k, Let go right-click
on those cells and unhide, unhide those cells. And we can see those in a
few different ways here. Now look again, just note that this kind of format
to set this up. Like I said, you won't see it in textbook problems as much
because they're trying to, they're trying to
focus in on what you might be able to
do with tables and formulas and on a test set and
when they take away excel. But when you have Excel, you can see how much more
flexibility this leads you to. I mean, you can come up with much more complex
scenarios or what you think is going to be
a future cash flow and not be restricted. If you're restricted to
something like this, then you start coming up with
future cash-flows scenarios that are too even you've
got too much perfection. If you're able to easily set
up a worksheet like this, which is quite easy to do. You can start to brainstorm in cashflows scenarios that
are going to happen in the future that are
more complex and possibly more closer
to real life and then actually be able to have more predictions and whatnot
of what's gonna go on. Obviously, once you set the
table up to you can change any of your data here
to like 8% and whatnot. And that'll change everything
in your scenario as well. And you want to practice setting
up your Excel worksheets like that so that you can
run different scenarios.
22. Future Value of Annuity using Non Annuity Excel Functions: Personal finance practice
problem using Excel, future value of an annuity. Using non annuity,
Excel functions prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down here
in the practice tab as opposed to the example
tab, the example tab, in essence D and an answer key, we have the information
on the left-hand side. We're going to
populate that into the blue area on the
right-hand side. First, starting off with the future value of
an annuity function, as we have seen it in the past. Then breaking out that function
into individual periods, which we will then have future value of one
calculations to get an idea of how the two calculations are
similar and related. And also because in practice, it can be quite
useful to break out the information into
a year-by-year basis, both because it gives you
more information about the annuity itself on a year by year or period
by period basis. And because it
allows you to have more complex type of scenarios. So let's see what
we have over here. We've got the payment
of 1 thousand. We're going to say
the rate is 7% and we have five periods this time looking into a
future value type of scenario. So we might have
a situation where we're estimating how
much we're going to be receiving in the future
to try to see where we will be at the
end of five years. In this case, nice
even payments. And we can work that out. But you might imagine a situation where you
have less even payments. And in that case you won't
be able to do a nice, nice standard
annuity calculation, but rather would have to do some combination of an
annuity and something else, or just break something
out year by year, which is very
common in practice. Something booked
problems don't often do given the fact that they
tried to take away excel. And so you can't really
use it to do that. But if you have Excel, it's very practical to set up your spreadsheets
in this format. So let's take a look at it. We're gonna say the
normal future value of an annuity will do this fairly quickly because we've
seen it in the past, will be negative
future value shift nine, we're picking up the rate, which is that 7% comma,
the number of periods, which is going to
be five periods over here, and then comma. And we are using
the payment portion because this is an
annuity up top, will pick up the 5
thousand that gives us our annuity of the 5,751. Now if we just look
at the cash flows, then obviously if
we just say we have the 1 thousand times five, that would give us our
cashflow of the 5 thousand. But because of the time value
of money or the increase, if we're thinking
of an investment, we would end up in a future
period amount of the 5,751 according to the
annuity calculation. We're going to go ahead
and format this one. Now let's break that
same calculation into a year-by-year calculation. We'll do it this way. I'm
going to say years 12. You're going to select
those two years and then use our autofill handle to click on the
autofill handle and drag it on down to five years. Center that by going to the Home tab,
Alignment and center. Then we'll just list
out our payments again, which will be equal
to the 1 thousand. I'm going to list each
of them out one by one. So I'm going to say F4 on
the keyboard and just copy that 1 thousand down to
the five periods F4, giving us an absolute reference, dollar sign before the B
dollar sign before the three. Enter. Putting our cursor back on that, grab the autofill handle, left-click on it, drag
it on down for the 1 thousand all the way
down five periods. Let's total this up toe down, which is gonna be equal
to the SUM of shift up, arrow holding down,
Shift Up, up, up, up, summing that column up, giving us the 5 thousand. Let's put an underline here, fonts group and underline. So now once we have this
nice setup process, we can easily then do a
future value calculation, but this time, do it on a
period by period basis. This is a little bit more
complex than we saw with the present value calculation because we're gonna be
going forward in time. We'll take a look
at that shortly. But just note, if you set
the table up properly, it's still pretty easy to do the future value calculation and be able to copy that down. Also note that if
it wasn't annuity, you might not need
this payment column. You can simply do
the future value and do an absolute
reference of your data, 1 thousand over here. But it was some kind of system where you do not have even
cash flows each year, then you'd want to set it
up basically in this way. So it's common to kinda set
up your payment flows over here and then line up the future value
calculation next to it. So now what we're
gonna do is we're gonna do future value of one calculations for
the five periods. And notice we're going
forward, not backwards. I'm not trying to bring this
back to a time period 0. I'm trying to go forward to
the end of the five periods. So that means this one is gonna be a future
value calculation. That's going to be future
value of one up four periods, 1234 periods here
instead of going back. So that complicates that
formula a little bit. When we compare that
to the present value, this one starts at year two, so it's got 123 periods. To get to the future
after five periods, this one starts at 32 periods
to get to period five. So let's do this calculation,
see what it looks like. It's gonna be negative
future value shift nine will pick up the rate,
which would be the 7%. When we copy it down, we would make that
absolute reference. But I won't do that yet
because we'll practice this a few times comma the
number of periods. Now this is where it's a
little bit different because what we want here
is four periods because we're imagining
this starts at the end of year one
because it's an annuity. So what we want is for
you can type in four. Let's start doing that first, let's put the four there
first and then comma. Then the payment
would be this one. It's not a payment
because it's not a it's not an annuity comma comma. The present value would be this 1 thousand and then Enter. And that would
give us the 100311 because we increase in it
for that four periods. However, I can't copy this down. If I was to take this and
grab it and copy it down, then I've got this
messed up thing. One because this, this moved down because I didn't make
it an absolute reference. So I could make that an
absolute or hit that one. And then, and then
also because I have to change this for because what I want it to
be as three now, because there's only
three periods, the left. So the question then is, well, how can I set this up so that
I can copy this thing down? And what you could do is
you could say, alright, instead of having four there, what I want is to
say this is going to be the five minus the one. And then I can use
this same kind of balanced table
that'll come up with for the problem with that
is when I copy it down, this five is going to move down. I don't want it to move down. This one is going to move down, and I do want that
one to move down. This first one right there, which represents the five. I'm going to put an absolute
reference on that F for putting a dollar sign
before the G and five, so that every time
I copy this down, that one stays the same. This one moved down. So
I should come up with three next time, which
is what we want. Let's test that out. I'm gonna put my cursor
back on it, copy it down. And I didn't do an absolute, I'm going to go back and run it again, this one right here. Let's put an absolute
reference on this percent, which is our normal
standard process. And then let's copy it down. And now it looks like it's
doing what we want, right? So this subtraction problem is taking five minus
two, which is three, which is how many
periods we want, because we're at period t, We want 123 periods left. And then you can copy that down. It's a fairly complex formula, but once you get, once you understand
it, it should be, you'll start to pick it up. Let's do it a couple
more times and then we'll copy it down
the rest of the way. So this one would be negative. Future value shift nine rate
would be that 7% comma, number of periods would then be, I'm going to do it this way. That would be the
five minus the two, which would be three. Comma payment, no payment
because it's not an annuity. Two commas future value
the 1 thousand and enter through it two
more times here, negative future value, shift nine, rate the 7% comma, number of periods is gonna
be five minus three, which gives us two. Which makes sense because
if I start at three, we got the two periods 45 left. Comma no payment
because it's not a present value of an annuity. So comma, the present
value is 1001 more time negative future value shifts nine rate at the
seven per cent comma, number of periods is going to be the five minus four or
one comma the payment, no payment comma
the present value, the 1 thousand and Enter. Now I'm going to delete it and I'm gonna do it one
more time being mindful of the
absolute references so we can copy them down. So I'm going to delete it,
do this one more time so we can do it with the
absolute references, negative future value,
shift nine, rate 7%, selecting F4 on the keyboard because that one is outside of our cell dollar sign before
the B and the four comma, number of periods is
going to be five. But I want that
not to move down. Here's the tricky one
because that one is in our table so that you
would think that I don't need to do anything
for that one because usually our table and
not outside in the data, we don't need to do anything, but this one's a little
tricky because that five is always the end date. So I want to make
that one absolute. I'm going to select
F on the keyboard and then minus the one. That one is not absolute because I do want it
to move down so that it's always five minus whatever
whatever year we are on, whatever period we are on. So we're going to say comma
and then comma again, the present values
at 1 thousand. I do want that one to move down, therefore, no
absolute reference. And so there we have
it. Let's copy it down and see if it does
what we would expect. I'll take the fill handle and
drag it down five periods. And then I'll just
double-click on it, Double-check one of
these and say, Yeah. It looks like it's
taking the five minus four or one would be there. The 7% is taken. The 1 thousand looks
right? So it looks good. And then if we sum this up, we're going to then get in the outer column underlying that font group and underline, we get once again to that 5,751. And we can see how each
of those payments, as we now bring it
into the future, results in a little
bit less in terms of future value dollars
because it doesn't have the time to basically accumulate the 7% gain or increase it, you're assuming will
happen by the time we get to the end of the
five-year time period. Now we can do this again
and format our table. This way. We can have where we
can have the years up top and we can have the
payments on the side. Sometimes this is useful
to do just in practice and sometimes people just like
to see it that way better. So we want to be able to
format our tables both ways so we can work with
other people that format their tables differently, possibly format or tables, which whatever way makes most sense with what we are
doing and so that we can follow along with anybody
else who once again is format in the table in whatever way they want
to format the table. So we'll put our
cursor on column C, drag on over to column I. We're going to hide those cells. Right-click and hide those
cells, hide those cells. And then we'll do it again. So the payment is going to
be equal to the 1 thousand. I'm going to select F4 and the keyboard, making
that absolute. So I can just copy that 1 thousand through
the five periods. Putting my cursor back
on that 1 thousand, you could do this
with a keyboard, by the way, instead
of the autofill, I could say Control
C on the keyboards, since we'll start practicing
more geeky maneuvers here, right arrow holding down shift, left or right, right, selecting those four cells and
then Control V pasting it. And we get the same kind of
process as the auto-fill. And you're more, you're
impressing the geeks, doing that. You're pressing the
geeks, which is good. Then we're going to then do
our future value calculation, which is going to be negative
future value shift nine. The rate is going to be over
here on the seven per cent. And let's do it a
couple of times. We would absolute
reference that, but those steward a
couple of times again, comma number of periods. Here's the tricky part. So we're going to try
to do it this way so we can pick it up
from our numbers, five minus the one, we would absolute
reference times the five. So I can copy it over, but let's just keep it
the way it is now. That means that it's
going to be for, which makes sense
because we have four periods after
period one here. Comma, no payment because
it's not an annuity. So two commas, present
value is the one above it. Then I'm going to select tab on the keyboard which
won't take me to the one under as inter would
but to the one to the right. Negative future value
shift nine, rate 7% comma, number of periods is
now the five minus the two comma no payments. So two commas present
value is the 1 thousand. Then we're going
to select tab on the keyboard and do it again. Negative future
value, shift nine, rate 7% comma,
number of periods is gonna be that five minus
the three to give us two. I think that comes out to two. If I'm doing my math properly, I'm not very good at
doing them in my head because I use Excel
all the time. But I'm pretty sure that one, okay, in any case,
there we have it. Now let's delete these
and do it again, keeping in mind the
absolute references necessary to copy
this thing across. So let's do it again
and say, Okay, this is gonna be equal to
the Future Value Shift Nine, rate 7% That one's
outside the table. So I gotta make that
an absolute reference. So I'm going to select
F on the keyboard, dollar sign before
the B and four, you only need a mixed reference, but an absolute reference
is easier to think about comma, number of periods. I'm gonna do it this
way. What the five, this is the tricky
one because that one, although it's inside the table, I don't want it
to move because I want that in number
to be the same. So I'm going to select
F4 on the keyboard. I think I hit F5 or something, something funny happened there, F4 on the keyboard. So there we have that.
And then minus the one, which will give us four periods. But this one, I do
want that one to move. Therefore, no absolute
reference there. Comma, comma present value
is gonna be that 1 thousand, which I do want to move, so I'll keep that one as is. There we have it. I didn't put a negative in
front of the f. So let's put a negative in front of the f to
make it a positive number. And then let's do our
copying and pasting with the keyboard Control C. Instead of a fill handle, you could use the fill handle to right arrow hold down shift, then right, right, right. And then Control V. And there we have
that it looks good. I would double-click on a
cell over here and say, is it doing what I want? Like there it is. And by the way, if
you don't want to double-click and you want
to do that in a geeky way. You can hit F2 on the keyboard, F2 to see what's in there. And there we have it. And so, yeah, it looks like it's doing what I would expect. Now let's sum up this way. Let's sum these things
up equals the SUM shift nine and left arrow holding
down shift left, left, left, left and enter and
sum this up equals the SUM shift nine left arrow
holding down shift left, left, left, left, and enter. So there we have that 5,751. Once again, let's unhide ourselves by putting
our cursor on column B, dragging on over to column K, letting go right-clicking on the selected area and unhide. So there we have
our calculations in multiple different formats, which again quite useful
to be able to do that. Something you won't
get in book problems oftentimes because they
take away your spreadsheet. But in practice, you can do a lot more complex
projections and possibly get a better conceptual feel
of what's happening from a period by period system or
period by period process. Which again, I think
I can give you some more insights into how you're putting
these things together.
23. Home Loan Payment Calculation & Amortization Table: Personal finance
practice problem using Excel home loan payment
calculation and amortization table
prepared to get financially fit by
practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab. The example tab, in essence
being an answer key, we have the information
on the left-hand side is going to populate that
into the blue area. On the right-hand side. We're going to do the
loan payment calculation as well as an
amortization schedule. This is very useful
when you're talking about a home loan
type of situation because it'll give
you a little bit more detail than you might have if you're just looking up the
calculation on the payment, which is usually what you end up looking up
when you're doing your calculations or working
with someone else to try to land or budget
into the future. Because the amortization
table gives you an idea of the
interests that would be paid versus the principal. And that can help
you out with tax calculations and whatnot if you're taking that into
consideration to note, the similar process can be done with any kind of
thing when you're doing a financing of a large
type of purchase such as a car or
something like that. The home loan is often
the more complex one, due to the fact that
just the length of it is often quite long. So the standard loan, we got, the 30-year type alone going
30 years into the future, which seems very, very daunting to make an
amortization table for, given the fact that that's a
long time into the future. But with Excel, we can do that and we can do
that fairly easily. So that's what we
will practice here. Also note, of course
there's a bunch of different loan terms
that could be out there. We're gonna go with the standard 30-year fixed
locking in the rate. So we'll have that
set up for us. So we're going to
say the loan is the 200 thousand note that when we're talking about the
loan for a home purchase, that's not the purchase price
of the home, necessarily. Most likely not generally. It's gonna be the loan
amount related to it. And then we're going to say
the rate is going to be the 5% on the rate. We're going to say the years
are going to be 30 years. And we're going to
say that we pay monthly note when you're talking about any
kind of financing, typically, they will they will quote the rate at
the yearly rate, even though most of
the times when we're financing things on
the personal side, we will be paying on a
monthly basis and they will work very hard to give
us the monthly amount and make it an even monthly amount so that they
can see if we're going to be able to pay
that and we can budget easily for
a fixed amount. So we're going to have to
deal with that rate and kinda into a monthly rate given the fact that we're gonna
be doing monthly payments. That's one of the complications
we'll talk about. Then we can calculate
the payment. When you're planning
something like financing and you're working
with someone to do so. Or if you're trying to
look it up yourself, then oftentimes you'll get
the payment calculation down and not the
amortization information. The amortization tables give you more insights and I think it's useful to be able to
put them together. Once we have this
all put together, if we do it properly, we can then change our data
and we can easily say, well, what if I have
$150 thousand loan? What if I have $100 thousand
loan and so on and so forth. And we can make a
much more complex and nuanced worksheet than we can basically with one just given us a
payment calculation. So let's see how
that would start. Now note, when we look at
this payment calculation that's similar to the
present value calculations. So the payment
calculation is related to the present value as we've
seen in prior presentations. I won't show that again. But we're extending on with these present value
type of calculations, converting it to basically using the payments component
of the present value. So in other words,
just, just so you know, if I was to say negative
present value and see this calculation has a payment component in it right there with the
payment component. That's what we're solving for this time would be the payment. First, we need to think
about the number of periods. Now if it's a 30-year
loan, we're gonna, we're gonna say that
there's 12 months of course, each year. So that means that we're going
to have equals 30 times 12 or 360 periods that we're
going to have to deal with. But again, that's okay because
we have Excel to help us. Now let's do our
payments calculation. Going to start with a negative instead of an equal and that'll flip the sign to make
it a positive result. And then I'm going to
say PMT shift nine. That'll start our argument. We have the rate, which is
gonna be the five per cent. But this is where
the tricky piece is, that's five per cent per year and we need it
to be per month. So we're going to
divide that by 12 and that'll give us
the monthly rate. And then comma, the number
of periods is not 30 years, but monthly periods
30 times 12 or 360, which we put in this
cell, in cell B5. And then comma, we're not, the present value is gonna be the loan amount that
we have up top, the 200 thousand on
the present value, and there we have it and enter. So we've got the 1074 about
double-clicking on it. There's our data, 1074. Once we have that number, then we can build our
amortization table, which once again seems daunting. 360 periods, but not a problem here
because we have Excel, we have Excel and
Excel makes it easy. So we're going to
say 12 are 012, and then I'm going to
copy those three sales or autofill them down, selecting them, putting our
cursor on the fill handle, I'm going to bring this
all the way down to 360. Notice it gives us
that nice little number format to help us out, gives us some help
there and we'll bring it all the way down. Say Man, that's taken forever. Are we sure we want to get into this giant table
that we're making. Sure we do. It's not a problem
because Excel can do it. And so then we have There it is. I'm going to then go home
tab, Alignment and center. And so there we have that. Then I'm gonna put the loan balance on
the right-hand side. Now note, one of the difficult
things on setting these, these amortization tables up is just to get your
columns Correct. So if you're doing this
for a test situation, you might want to practice
settings your columns up so you can build your
table appropriately. But once you have them set up or if you have a template
of your tables, then it's fairly
easy to populate. The loan balance is going to be equal to the 200 thousand. That's where we
start at period 0, the payments are all
going to be the same. That's the point
of the payments. Whenever they forced the
payment to be the same, even though the interests to be changing from period to
period or in other words, the interests changing
from period to period is the cost that we pay for basically having the
payments be all the same. That's the confusing
point of it, so that we can make the
payments nice. And even. So we're gonna say the
monthly payments we already calculated to be that 104074. I would like to make
that an absolute reference so I can copy it down. If I were to copy it down, we will do this a few times. However, I would select F4. The interests then would be calculated by taking
this is going to be equal to the prior
balance times the 5%. That would be for a year though. So we've got to take
that and divide it by 12 to get the monthly amount. In other words, if we pulled
out the trusty calculator here and did it within
the trustee calculate, we can take the 200 thousand
times the 0.05 or 5%. That would be 10 thousand
if it were for a year divided by 12 months
monthly rate, 833.33. So then we could do it this way, which is kinda how we
think about it in Excel. Sometimes 0.05, that's gonna be the rate for a year divided
by 12 monthly rate. Is that ugly small number, which is why we don't talk about monthly rates even
though we might use them in the calculation, times the 200 thousand. Once again, getting
us to that 8.3333. So if this is the amount that we're paying and the interests, which is the rent that we're paying kinda like for the use of the purchasing power
and a similar way as when we were renting before
we purchased the home, which has paid the
rent for the use, and we never get to see
that money again, right. It's just goes away. That means that
it's going to be, the difference between those
two will be the reduction. So the payment minus
the interest is how much the loan balance
will be going down by. So this is going
to be equal to the 200 thousand minus the 240. And this case, notice that
the bulk of it during the beginning of the
loan is going to interests as opposed to
the reduction of the loan. And then towards the end
that will switch and change. If we do this again, I'm
going to say, Alright, the payment is again 1074. Now the interest is going
to be slightly less given the fact that the
loan balance has gone down. So it's gonna be this
199760 times the 5%. I'm not going to do the
absolute reference right now. I'm just going to
calculate it a few times. And so I didn't divide it by 12, then divided by 12. And there we have it. Then
if I subtract this out, we got the 1074 minus
the 832 gives us the reduction in
the loan that the 241 slightly going up here, slightly going down
on the interests. That means that
the prior balance, the 199760 minus the
241, gives us 199518. Let's do it a couple more times, like three more times here. We've got the payment. Interest
is going to be equal to the 199518 times the 5% tab. The reduction in the loan
is gonna be the 1074. Hold on a second. I didn't
divide it by 12 again. I'll get it right one of these times I'm going to
take that that would be the yearly amount
divided by 12 tab. Then we're going to take
the 1074 minus the 831 tab. Then we're gonna be
picking up the 199518 plus or minus to 42. And that brings us
to the 199 to 76. Let's see if I could do
it cleanly this time. This is gonna be the one O 74 interests is now gonna be the 199276 times the 5% divided
by 12 gives us the 830. And then we're going to take
this as equal to the payment 1074 minus the 830 and tab. Now we've got the prior balance, the 1997276 minus the 243. Let's do it one more time. This equals the 1074. This is the new balance, 2199033, times the
five per cent. And then take that
divided by 12 tab. The reduction in the loan
balance is the payments minus the amount that's
going to interest tab. And then our new balance
is the 199033 minus the 244 and entered
given us the 298788. Let's do it again. This time. We're going to just figure out what we need to
do to copy it down. Then we'll use our
autofill to do so. Notice that these
changes are fairly small on an incremental
month by month basis because the
loan is going out so long and we've got the 5% rate. But over the three-year
time period, this will have a
significant change towards the beginning
and end of the loan. So I'm going to delete this
and do it one more time. Being mindful of what we need to do to be able
to copy it down. So it using our absolute
references and so on. So we're gonna do
this to the payment that we're going to have is just gonna be equal to the payment
we calculated down here. That's outside of our table. I want it to be the
same all the way down. So I'm gonna make this
an absolute reference, selecting F4 on the
keyboard dollar sign before the B and six. Remember you only need
a mixed reference, but an absolute reference works and it's easier to think about, then the interests
will be equal to that 200 thousand times the 5%. That 5% is outside the table. I don't want it to move
down when I copy down. Therefore, I'm going to make
it an absolute reference selecting F4 on the keyboard. Instead of tab I hit Tab F4 on the keyboard dollar sign
before the B and two. Then I'm gonna divide that by 12 and I'm just going
to hard code the 12, meaning it's going to copy
down as we copy down as well. Hardcode, meaning
typed it in there. Then I'll subtract
these two out. This is going to be
equal to the payment, the 1074 minus 833 interests. Both of those I
want to copy down. Both of those are inside
the table, therefore, no absolute reference
needed on either of them. Tab, then we got this
equals the loan balance prior to this minus the
240 reduction in the loan. Both of those are
inside the table. Both of those I
want to move down relative as I copy
the formulas down. Therefore, no absolute
reference needed there either. So then we can just copy these. Now, normally I would select
these three or four cells, copy them down one time, grabbing the fill handle, dragging it down one time and double-checking that it does
what we think it should. This one looks correct. This one looks correct. So this one looks
like it's doing what we want and so does this. So we'll copy it down. Once we get all the way
down to the bottom, the loan balance should be 0 after 30 years or 360 periods. That'll give us an indication that we've done this properly. So we'll grab that
fill handle again, drag it all the way
down to the bottom, which is 360 periods. And you can see how
this would be very difficult to do by hand without some kind of
computer to do it. But with Excel done
magical, and there it is. The end is at 0. I can see that at the bottom
line here are payments, now are almost all principle
out of that payment. And we made on the last one, we only paid $4 of interest. And it was all principle here. Now notice that's not really a problem for budgeting purposes because you're saying that
whatever I can pay the 1074, what do I care? How much is broken out between
interest and principal, but one, You gotta, you gotta care to the point
that fact that you're paying interest is like the
rent that you're paying over and above the value
of the loan amount. And to the fact
that you could have tax implications on this as well that we need to
take into consideration. So that's the next step you can kinda look at if you
were financing this. Most of the times
you talk to people, they'll only give you this
number and they'll say, well, how much can you afford? And they'll just increase in, decrease this number right here. But really you want to know how much interest
you're actually paying. You kinda concerned with the interest rate and how
much interests you're paying. And you then can start to
think about tax impacts. Because in this first
year, the interests, if I was to try to figure out the interests for
the first year, equals the sum of the interests column for 12 months would
be these cells right here. So then I can say, well,
that's how much I'm paying in interest
for the first year, which will differ
from the second year, which would be the sum
of 24 up to up to 13, I believe, would be different. I'm paying slightly
less interests. And when I start to talk
about the tax implications, the interest becomes important. And you gotta be careful with the tax implications
because it gets quite confusing as to whether your standard deduction or you have an itemized deduction, then you can take
into consideration whether or not you can write off like the the the the
taxes related to.
24. Retirement Plan Worksheet: Personal finance
practice problem using Excel retirement plan worksheet, prepare to get financially fit by practicing personal finance. Here we are in our
Excel worksheet. If you have access to
the Excel worksheet, would like to follow along. Note that we're down
here in the practice tab as opposed to the example tab, the example tap in essence
being an answer key, we have the information
on the left-hand side. We're going to populate
that into the blue area. On the right-hand side, we're looking at a
retirement type of scenario. Our major goal is to take some of the tools that
we've gotten with these present and
future value time value of money calculations, put them together
as we think about a fairly complex
decision process, one of the most complex
decision processes we have when we're talking about personal finances
and that's typically the retirement setting,
the retirement planning. Why is it complicated? Well, it's far out
into the future. We're thinking about
what's going to happen in the future. We don't know what
the time value of money is going to be
with regards to how much we're going to be
earning in the future with regards to our
savings accounts, we don't know how much
we're gonna be able to earn over our earnings years, meaning how much our cell we
will be able to increase, how much will be able to put
in to the savings account. We don't know exactly what
our life expectancy will be. So we have a lot of
unknowns that we kinda have to put into a scenario. Many of those unknowns
being specific to us, which is why when
you think about a standard cookie cutter type of retirement plan calculator, none of them are gonna
be that great really because they're gonna
be hard to understand, because they're going to
make a lot of assumptions that you may not
see transparently. And also, there's so many different variables
that it's hard to know what exactly is going on with a
standardized type of thing. If you can take some of these tools and put
them into a worksheet, then you can, you can customize your retirement plan a little
bit more, more easily. And you might also
be able to get a better grasp of what is
actually happening with it. Also, you can make some more customizations with your Excel worksheet by changing the data for different scenarios to update it and whatnot as
you, as you work with it. So we're just going
to use some of the tools to basically
practice some of the concepts with relation to a retirement plan that you might then take and then
put together and put a more customized
plan for yourself on. So here's gonna be
the basic data. We're going to say first
we got the retirement age. Remember there's two
kind of things do you got to keep in mind when you do the retirement one is at the point in time
that you retire, you're no longer earning
money through your earnings, through revenue, although you have earnings from your savings. And then your nest
egg is going to be going down at that
point in time, although you'll still
be generating revenue, you're gonna be
pulling more money out then you're generating. So the question is,
how much nest egg, how much money do you need in
order to last you the rest of your life to live in the comfort that you
want to be living in. That's kind of an
annuity calculation that you gotta get
to that point, then you can think about
during your earning years, how much you would
have to put away, say on a yearly basis or so on to get to that point in time after retirement
point to have enough that you can then eat
into it going forward. Okay, So here's our information. We've got the retirement age, we're going to
assume it's at 60. We're going to assume
we live to a 100. We are going to live to a 100. They got the yearly
spending at 75 thousand. Now note this is another
unknown kinda component because you might look at your current spending
and estimate what you're going to need to
spend at retirement. And then you might actually do a time value of
money calculation, accounting for inflation,
which is like one to 3%. To think about how much
you can spend to earn the same amount or live the same way you're
currently living now. So that's another thing
you can kind of consider. We're just going to
assume 75 thousand. We're pulling out 75 thousand
a year at retirement. And then we've got the rate,
we're going to say is 7%. Another unknown
factor, of course, meaning we're going to try to average and say we're
going to earn average over this life and whatnot
of the 7% on our savings. So when we put it into
our retirement plan, we put it into our
stocks and whatnot. We're going to assume an
average over that time of 7%. Now, people will argue what that percent can be and whatnot. But if you're investing
over a long term, then you're more likely to get a reasonable average percent
over that time period. So you can talk to your,
basically your finance, financial people to see
what that percent will be. But just remember
if you're thinking long-term investment, hopefully over that long
term, you can get a nice, even fairly good return
on it would be the idea, even though it's going
to fluctuate in-between that time period and
it's going to drive you crazy on the downturns
at least, right? So then we're going to say
that the current savings we currently have 10
thousand already. And the years from
years to retirement, the years that we
have to retirement, we're going to say is 30 years. So we have 30 years that
we're gonna be able to save. So before we get to
retirement age 60. So that's how much
time we have to build up our income
to get there. Now, this second component, we're going to do
this when we get a little bit more
complex of a scenario. Because when we start to think
about our savings plans, we can get more nuanced on that later and so we'll
talk about that later. So let's first just
think about, okay, well, how much would I
need then if I'm gonna be picking up 75 thousand, spending 75 thousand
a year after, after 64, until I turned a 100 and then
I die right at 100. How much, how much would I need at that point in time
in order to have enough in my savings
account to be eaten away at it at 75 a year. For that, we do
our present value of an annuity calculation. So I'm going to say negative. Present Value Shift Nine, the rate I'm going to
say is seven per cent. We're gonna be earning 7% on it. Comma, we got the
number of periods, which we're going to say,
I'll do it this way, is the 100 minus 60 is how much time we're
going to spend from the retirement age to a 100. So we're going to say, alright, and then the payment
is going to be, the payment that we have is 75. We're going to have the 75 that we're going to be spending. That means at 60, we're going to need 999878. So that's how much
we're gonna we're gonna need at the point of
retirement if we're just gonna be eating
away at that for the next 40 years, and
then we'd be in there. It'll be down to 0 after a 100. So then we've got the
target there of the 999878. So now we've got to
think, okay, well, what do I gotta do to get there? So I've got 30 years now. I've got 30 years to
get to that. 999878. And how am I going to do that? Well, I already have 10 thousand and I'm going to assume
that that's 10 thousand. I'm not spending
that's 10 thousand in my savings account
for retirement. What's that? What if I don't
do anything and I just leave that
there and it grows at 7% until retirement
for 30 years. That's my baseline. Well,
if I don't put any more in, I just calculate that one. I'm going to say that's
going to be equal to the negative future value. The rate is going to be that 7%. We're going to imagine it
grows at the 7% again, comma, we're going to say the number of periods
is going to be 30. We've got 30 years for that
to grow before we get to 60. And then comma, the
payment is going to be then the ten thousand,
ten thousand. So there we have that. That
means that hold on a sec. It's not a payment.
Let me delete that. It's not a payment. That would be an annuity. We're going to say comma comma the present value
because I'm not putting this in every year. That's how much we
currently have. That would be the present value. There we have it
that would give us a future amount at 60 of 76123. That's where we would
start at or that's what we have thus far if we
assume it just to grow. Now the difference between the two is what
we're going to have to start putting
in at that point. So that means that we
have a difference of 999878 minus the 76123. That means that we're
going to have to get an compile another 923756 over our life over the next 30 years
to get to that point. Now then the easiest
calculation would be, well, how much would I
have to put in on an annuity calculation in
order to get to that 923756, how much would I have
to put in each year? Now, that's gonna be the
easiest calculation, but it's not very nuanced because if we're
starting off in our, earlier in our career, we probably have less money maybe than we might have
in our peak earning years. So that means, that means that later on we'll
get a little bit more nuanced and try to
think about how much I can put in if I had more money to put it in
because obviously I'm limited to how
much I can put in. I can't just say I'm going
to normally need to put in or be able to put in
more when I earn more. But if I was to put it in a nice even amount
over 30 years, we can do a nice
annuity calculation. And what we're
gonna do a payment, we're gonna do a payment
formula which is a different or an alteration of the present value and
future value formula. So I'm going to say negative
to flip the sign PMT. We can then say the rate is
going to be the 7% again, comma, number of periods, we're going to say
is 30 periods. And we're going to say comma. And the present value
that we need is, I'm going to say two
commas because we actually need a future value. We need the future
value of that 999878. Actually, sorry, we need
the future value of the 923756 and then Enter. And that will give us the 9,779 that we'd have to
be putting in each year. We would assume in
order to get to that to that added
amount that the 923756. So that would be a
basic kind of scenario. Once you have this
kind of setup, then you can change your
data over here and you say, well, what if, what
if this was 8%? What if this was 10% and
so on? What if it was 5%? Now, if you want to make that and that's gonna be
a basic scenario, note that we will
then do it a little bit more nuanced in a second. But let's first run
some tables based on this scenario is just
to give it a little bit more concrete in our minds. So if for example, we thought about this 999878
and just kinda verify in our minds that I'm
going to have that for 40 years and spent 75
thousand for 40 years. How does that work? Let's run a running
balance table for that. And say at the time
of retirement, which is when we're 60, we're going to say then
from period 01 and so on, we got 40 more years
until we die at 100, we are going to
die right at 100. Or if we, if we
live more than 100, then we're going
to be penniless. But that's okay. We're gonna we're gonna go to the Home
tab, Alignment and center. Then. We're going to say here that our investment is
going to be this. This is how much we
have when we'd retire at 60 that we're going
to start eating away at. We're going to start
eating away at it. So that means if we're earning a 7% return each year, we'd say, okay, in the first
year after retirement, we'd have that
999878 times the 7%. I'm gonna say F4. I won't do it yet. I'll
just multiply that out. That's how much we would earn, but we're taking out negative
75 thousand each year. So then what's going to
happen after year one, we would have the 999878 plus the SUM left holding
down shift of those two. And that would give
us the 994870. Now I'm going to copy this
down after I do it this time. So I'm gonna do it again,
but this time thinking about the absolute references
needed to copy this down. So this then would be
the 994870 times the 7%. The 7% is outside of my cells. I'm going to select F4 and
the keyboard dollar sign before the B and for tab. And then the expenses
are going to be negative of that 75 thousand. Then I'm going to spend, I want that to be an absolute
reference as well, not to, not to move
when I copy it down. So F4 and the
keyboard dollar sign before the B and three tab. And this is gonna be equal
to the one above it plus the SUM shift nine left arrow holding down shift left again, closing up the
brackets, shift to 0. So there we have it. Now
I'm just going to copy this down and this should decrease. Our investment will slowly
decrease for 40 years. If I copy this down until
we get down here to 100, at 100 were like I'm going
to spend my last penny. And then we keel over and die once we've spent
our last penny. And there it is. And you might want more
of a cushion, of course, then than that if you're, if you're planning to be a 100, I probably won't
make it do a 100, but I feel like that's a
cushion already for me, but any case, we have that. And so I can kinda verify
our calculation there. So now let's think about
this savings amount. If I put this if
I put this away, each period, will I
really get to that 923. So we can verify that or give us some a little
bit more nuance on that. So I'm going to hide
some cells to do that. I'm going to put my
cursor on column F, drag over to j, let go,
right-click and hide. So then let's do
this. Do this again. Now, this is going to
be for 430 periods. So I'm going to
start here at 12, and it's gonna be
selecting these two. I'm going to drag it on down, autofill down to 30 periods. T periods is going
to be right here. And then I'm going to scroll back up and we're going to say, Alright, so the payment
that we're going to have, we're going to say that this
payment and notice we're starting because this is
an annuity calculation. We're starting basically at
the end of the period one. And let's center those two. I'm gonna go to the
Home tab Alignment. We'll center these. And then let's say
the first payment we're going to say is that 9779. And that's going
to be our savings. So that's our savings. And then in period
two, that's when we'll start calculating the earnings for it to match our annuity
or an annuity calculation. This is going to be
equal to then the 9779, we're going to say
times then the 7% that's outside the table. So I'm going to say F4 on the keyboard so I
can copy it down. Dollar sign between the B and for before the B and for tab. And then we're going to say the payment amount is
always gonna be the same, which is going to be
equal to that 9779. I want that to copy down or not to move down
when I copy it down. Therefore, F4 on the
keyboard dollar sign before the E and seven. And then our savings
account is going to be equal to the amount
we had before plus the sum of both
the earnings on it and the payment closing up
the brackets and Enter. So this one's going to be going up by earnings and payments. That should be good
to copy that down. And once we get to the bottom, we should be able
to verify this by checking it to this number just to double-check
that that would indeed give us get
us to the 923756, which is the added amount we need considering the fact
that the 10 thousand we're assuming is going to be
earning or get us to the 76123 by the time we get
to retirement at 60. So we'll put our cursor
on the fill handle. We'll drag this
down and say, Okay, That gets us down here
to the 923923756. So that verifies this number. It gives us an idea of
the earnings that are being populated, that format. So next, you might want to kinda combine these
together and try to do a running balance that combines our total investments
since we're earning 7% on the entire thing. So that could look something
like this just to, just to see how these
running balances can be kinda put together in
multiple different ways. Putting my cursor on column K, adjusting to call them. Oh, let go. And we're going to
hide those cells. So now I'm going
to try to get back to this number up top. And I'm going to include
the fact that we already have the 10 thousand
at time period 0. And see if we can
basically do are running balances and
get to that number. So let's start
with, in this case, we're going to start
at time period 0. Which means we have the investment already
in place of the 10 thousand and we're
going to assume we're earning 7% on that. So I'm going to then have
period one and period two. We'll drag this on down,
auto-filling that down. We're going to say
dragging that on down to the 30 periods. Let's center that Home
tab, Alignment and center. So then we're going to the
interests can be calculated as that 10 thousand the prior
balance times the 7% earnings, which we want to make
an absolute reference. So I can copy it down
by selecting F4 on the keyboard dollar sign
before the B and four. And then we're going to say
the payment now starts here. This payment is
going to be equal in this 9779 that we're going to be putting in each year selecting F4 on the keyboard so
we can copy that down. It stays at the same cell. Then the investment is gonna be the 10 thousand plus the sum of the amounts to
the left shift, left again and hold
down shift and 0. And then we should
be able to copy that down and
hopefully get to this 999878 by using their
auto-fill auto-fill feature. So there we have the 9998787. Combine them together on our table to look at
our at our earnings. Let's hide these cells
by going from P, where to put my cursor
on P and scroll on over to t. Let go, right-click and
hide these cells. Now, the other way you might think about this
is you might say, well this is good, but I don't think
I'm gonna be able to put the same amount
in each year. What if I don't start putting larger amounts
until later years, which most people have to do. I can't I can't start putting that big amount in
my early years, I don't have the
money, but maybe later I can put in more money. And so what if I put it together a scenario like
this, I'm gonna say, well, for the next 30 years that
I have until I get to 60, I'm going to say that my
earnings for years one through five are
gonna be 45 thousand. Years six through
ten are going to be 55 thousand and then 11 through 2055 thousand for six through 1011 to 20, there's
going to be 65. And then from 21 to 30, I'm going to be
earning 75 thousand. Now, if that's the case, I would be able to afford
possibly putting more money in the later years of my work
life than the early years. And I might want
to take that kind of nuance into consideration. One way we might take it into consideration is to say, okay, what if I tried to put some
percent into into retirement? Let's just pick a percent here. I'm going to choose like 5% that I'm gonna put in of
my earnings to start with. And then I'll run my
running balanced table. And then I'll try to change
that cell using Goal Seek to whatever it needs to be in order to get to my objective, which is going to be in
this case that 923756. So let's see how
this might work out. So we've got our same 3030 years here, we've got 30 years. I can't use an annuity
now because it's complex. I'm going to have to
use the future value of one type of calculations. We can do this in a couple of different ways. So
let's try this. Let's say if I go 12, I select those two and
I copy that down to my 3030 years here. This one will actually be
the total downhill sold, total it up, down below. And then let's go ahead
and center these. I'm going to select these items
and center that Home tab, Alignment and center.
So there we have that. And then let's say, let's put our income
down on each line out. Now you don't need
this. You could take your data from over here. But I'm gonna, I'm
gonna try to pick up my income by saying this
is going to be equal to, this is what I imagine
we're earning each year. I'm going to select
F4 on the keyboard and just copy that on
down for five periods. So I'll copy that down
for five periods. And then I'll try to
figure out where I will be on a future value from
a year-by-year basis. Now you might say that looks like an annuity
for five periods. We could use a combination of annuity and future value of one. We'll take a look at that
in a second as well. But having a year-by-year
calculation can be just as easy
to do with Excel. So let's check that out. We're going to say,
alright, and then in your six, we got this 55. I'm going to select F4 that
we're gonna be earning and we're going to earn that
from your six to ten. So autofill that to your ten. Then in year 11, we're
going to earn 65, we believe F4 on the
keyboard and we're going to earn that will say
from 11 to 20. Then in year 21
we're going to earn 75 F4 on the keyboard. And then we're going to
copy that down until we retire at 3030 years. Then what we're gonna
do is take 5% of that. There's 5% which I'm
going to apply to each one of them and I'm
going to keep that cell nice. And even so that
I can then change that cell to whatever it
needs to be to meet my goal. And that's what that's the plan. So I'm going to say right,
that means I'm going to invest 45 thousand
whatever my income is, times five per cent. I want to make that 5% an absolute reference so
we can copy it down, selecting F4 on the
keyboard. Copy that down. That means I'm going to take
out of my 47,000 to 50. Probably not gonna
do it to get us to that goal, but that's okay. That's our starting point. Copy that down. And then obviously we're taking more out because we're taking the same percent out of a larger income as
our income increases. Now we'll do a
future value of one for each, each year here. So we'll do our
future value of one, negative future value
shift nine rate. We're going to assume 7% growth
comma, number of periods. This is the tricky part. I gotta, I gotta take, I'm at period one
minus the 30, so 29. I'm gonna do that by
taking my end number. So I can copy this down easily. The 30 way down here, make that absolute by
selecting F4 because I want that to stay the same minus
the beginning number. And that one I want to copy
down when I copy it down, and that allows me to easily
copy this thing down. I also want an absolute
reference on the rate, F4 on the rate, and then comma it's not
an annuity this time, so no payment two commas
present value is going to be that 2 thousand
to 50 and enter. So hopefully I did that right. I'm gonna go ahead and copy
this down. I believe I did. We'll do a double-check on it. We'll put our cursor
on the autofill, drag that down,
dragging that down. And so that's gonna
be our total. Then, then we have
our total down here, which I can sum up. I can sum up and say, all right, what does that get me at 30, where will I be in future
value if that's all correct? I would be at the two
seventy five sixty seven, which doesn't meet our
goal of the of the 923756. So then I can say
well, okay, well, how much would I have to put in since I can just change this? I can say, well what if I make, if I take 10% of each? Now, I'd be putting in 4,500 here and then
6 six thousand, five hundred, five
thousand, five hundred. And that would add up to 543. So that's getting closer. And then I can use
11% and so on. And try to see what happens. Or I can use goal seek
to say, Hey, Excel, would you change this cell
to get to this end number to be the same as where
I need it to be to meet my objective
that 923756. So we could say all
right, let's do that. Let's go to goal seek data tab, what-if analysis and the
forecast Tools Goal Seek. And I want to say Excel, would you set this
cell down here, that cell to be I got
a hard-coded in there. I want it to be 923756. Please do that by changing the percent that I'm
gonna be taking out of my wages based on this
projected income and Enter. And then it's going to
even it out for us. So there it is. So
it's done that for us. And then they're
saying about 17% is about how much we'd
have to be pulling out. Which means when
we're earning 52,654, when we're earning fifty
five thousand nine thousand, three hundred fifty
four and sixty five, the 11,055 and so on. These are some ways you can
get a lot more nuance with this type of calculation than just a straight
annuity over 40 years. Now also note if you see something like this,
you might say, well, doesn't that look like for
separate annuity calculations? Why don't I do four separate
annuity calculations, which you can do, and that could simplify things. But there's a bit
of a twist to it. So let me just show you that
as well as you can kinda combine the present value
of one and the annuity. So let's put our
cursor on this cell. I'm going to drag on over to y. Let go, right-click
and hide these again. And let's try to do this in like a grouping of annuity groupings. So I'm just going
to say this will be equal to this grouping. And then we'll just copy that down. So there we have that. And this is going to
be our total tau. And say, let's just calculate our investment now
for this time period, which would be the 45
thousand times this percent to 17% or the one
we calculated around 17%. I want, I want this to stay the same and these
two to copy down. So I'm going to select
F4 on the keyboard. So I'm taking 17% of those three numbers by
auto-filling this down. So 17% of the fifty-five, seventeen percent
of the 65 to seven, 3% of the 75 represented here. Then I'm going to do my
annuity for five years here. For, what is it? Five-years here, ten years
here, ten years here. Now the problem is that once I do my annuity
for five years, I'm left off at the
end of year five. And that money is still, is gonna be generating
revenue until I retire up to 30 here. And that's why I gotta
do two steps when I, when I do this kind of method. So for example, I'd have to say negative future
value shift nine, the rate, we're going to say 7% growth comma,
number of periods. I'm gonna hard-code as
five from years one to 55. We're going to say comma. And then the payment
is going to be, we're going to assume
that amount is the amount of the payment and enter. So that gives us the 4414, But that's at the
end of period five. If I keep that in my investment account until
the end of end of retirement, we're going to have to say then I'm going to have
more money, right? So then I got to say, Okay, let's do a future value of one, which would be the rate comma, the number of periods, which I'm going to say
is 30 total down here, minus the five, which is
where I left off on this one. That's how many more
periods are gonna be there? 25. And then comma. Comma. It's not a payment this time, but it's because it's not
an annuity present value of one for that 44. That means that's going to
bring us up to the 238880. So let's do that again here. This is for another five years, negative future
value shift nine. The rate is gonna
be the 7% comma, number of periods is five again, because it's six through ten. Comma in the payment's
going to be that 9354. But that's at the end of
year ten and I got till you're 30 for it to keep
on earning less money. So we gotta go Future
Value Shift Nine rate is gonna be the 7% comma, number of periods is going
to be then let's say 30 minus where we
left off ten comma. And then comma again to get
to the present value is this. And so there we have it. So we are actually 208167. And then this one negative
future value shift nine, rate 7% comma number
of periods is ten. Now 11 to 20 comma payment
is gonna be that 1155. And then I've got another
ten years to get to 30 here. So negative future
value shift nine, rate 7% comma number of periods, I'm going to say
30 minus the 20, which is where we
left off or ten comma not a payment because
this is not an annuity. The present value is that 150
to 742 enter one more time, negative future
value shift nine, rate 7% comma number
of periods is ten. Comma payment 12756. That's going to
end at period 30, so nothing else needs to happen. Summing that up. That's another way
we can get to that, to that 923756 that we got here. So you might see it
grouped in that format. And this is a little
bit easier to look at this way as well. Although the running balance
for 30 periods was just as easy to construct
and you can get more nuanced in your calculations. And then of course you
could change these and say, well what if I made 8, 8%? If you've got
everything structured properly, you can see what's, what's your earnings would
basically be and everything should kind of be
able to be adjusted. If I change this back to seven, what if I wanted to spend like 100 thousand because I
think there's gonna be inflation or something like
that for the whole time. Hopefully that will calculate. So everything, everything
will populate for itself, although we use Goal Seek here. So this one, you know, that Goal Seek is going to not, not account for this one
will have to adjust that. But in any case, you can see how using your data
over here will help you to kinda make adjustments and
adjust these things. Let's go ahead and
unhide some cells. We're gonna put our
cursor on E to the W, a right-click and unhide. So like I said, the
basic idea is you can do a general kind of concept for the year projections
and this format, but this doesn't give
you a lot of nuance. And this in particular
limits you to the fact that you're not
gonna be able to put in an even amount each year. And then you can
try to project what your earnings will
be in the future and how much you're
going to put in. And you can kinda get
a feel of the cost of you waiting later
until you put in money. Because if you put money
later in towards retirement, you're not getting
the earning that you would have if
you put it in early. But of course, you
can't put it in early because you don't
have the money early. You can only put in the
money that you have. And you can kinda balance
those two things out when you get a more nuanced
type of calculation. And that obviously
means you've got more complex type of
table and you might have to move from an
annuity calculation to future value of
one to two mole, that kind of thing over.
