USING EXCEL FOR TIME VALUE OF MONEY CALCULATIONS
Once you get familiar with these functions, you will be able to directly type in the information,
but to start, it is easier to let EXCEL lead you lead you by the hand.
To use these functions, click on “insert”, “function”, then choose the category “financial”.
PV (Present Value Function)
EXCEL’s PV function computes the present value of a lump sum payment and/or an annuity.
The function has the form:
=PV (discount rate, number of periods, payment, future value, type)
The Pv function asks you to insert values in cells for:
Rate:
which is the discount rate
Nper: the number of periods
Pmt:
the amount of one payment in the annuity (if there is an annuity)
Fv:
the lump sum of money to be received/paid in the future (if there is one)
Type: type is important only if the present value involves an annuity; type = 0 if
the first payment in the annuity is one period from today and 1 if the first
payment in the annuity is made today.
Example 1a: A wealthy relative wants to put some money in a savings account for you today.
She wants you to receive $15,000 from the account in 6 years; the bank promises her it will pay
interest of 5% compounded annually on the money she deposits. How much should she deposit?
You would enter:
Rate:
5%
Nper:
6
Pmt:
Fv:
15000
Type:
Answer ($11,193.23) the answer is negative to indicate that she
would have to pay that amount of money to the bank.
Note:
Pmt and Type are left blank, since this isn’t an annuity
Example 1b: Another wealthy relative wants to put some money in a savings account for you
today. She wants you to receive $15,000 from the account in 6 years; the bank promises her it
will pay interest of 5% compounded monthly on the money deposited today. How much should
she deposit?

Example 2a: A third rich relative of yours wants to deposit some money in the bank in Example
1b; however, he wants you to be able to withdraw $2,000 a month from the bank every month for
the next 20 months and have a zero balance in the account after the 20th month. He wants to
deposit the money today and wants the bank to start giving you your checks one month from
today.

to start giving you your checks starting the day he makes his deposit.

Answer ($38,461.81)
Example 3: (Chapter 9 material) X Corporation wants to raise some capital. They offer you a
bond which has a face value of $10,000, a stated annual interest rate (or coupon rate) of 6% (paid
twice a year starting 6 months from now), and a maturity date 20 years from today. You want to
earn a return of 8% compounded semiannually. How much would you loan X Corporation?

8%/2

Fv:

Type:
Answer ($8,020.72)
FV (Future Value Function)
The function has the form:
=FV (discount rate, number of periods, payment, present value, type)
The Fv function asks you to insert values in cells for:
Rate:
the discount rate
Nper:
the number of periods
Pmt:
the amount of one payment in the annuity (if there is an annuity)
Pv:
the lump sum of money to be received/paid today (if there is one)
Type:
type = 0 if you want to know how much money there will be
immediately after the last payment; type = 1 if you want to know
how much money there will be one period after the last payment.

Example 4: A wealthy relative wants to deposit $15,000 in a savings account in the bank in
Example 1b today for you. She wants to leave the money in the bank for 6 years The bank
promises her it will pay interest of 5% compounded monthly. How much will be in the account
in 6 years when she instructs the bank to send you a check for the balance? You would enter:

Pv:

Example 5a: Another rich relative of yours wants to deposit some money in the bank in
Example 1b; he wants to deposit $2,000 a month in the bank every month for the next 20 months

PMT (Payment Function)
Example 7a. (Chapter 10 material) You lease a machine to a customer. The machine has a fair
value of $70,000; the lease period is for 4 years and the lease contains a guaranteed residual
value of $8,000. You charge the lessee 8% compounded monthly. The first month’s lease
payment is due one month from today. How much should each lease payment be?

Answer $1,566.93
Note: Pv is entered as negative; Fv and the answer are positive since you will be
receiving the Fv and the lease payments.
Example 7b. (Chapter 10 material) You lease the same asset as in Example 7a under the same
terms, except you want to receive the first lease payment the day the lease is signed (which is
more common):

RATE (Implicit Interest Rate Function)
Example 8. You want to buy an asset; the seller tells you the price is $10,000. You ask if you
could get the asset today, but pay for it in the future. The seller says “Ok, if you pay me in the
future, I want you to pay me $600 in one year, $600 in two years and $10,100 in three years.”
You want to determine what interest rate the seller is charging you.

NPV (Net Present Value)
The function has the form:
= (NPV, Value1, Value2,…)
Example 9 Your cost of capital is 8%. An opportunity arises to invest in something that will
cost you $8,000 one year from today and $1,000 in one year later; you think that the investment
will repay you $2,000 at the end of three years and $3,000 at the end of years four through seven.
You should invest in the project if the present value of what you will receive will exceed the
present value of what you must pay – that is, if the net present value is positive.
Rate
8%
Value1
-8000 (payments you make are negative)
Value2
-1000
Value3

Value4

Value5

Value6

Value7

Answer $1,210.74
Note: if the answer, above, had been negative then the return on the investment would not cover
your cost of capital
As you can see in the financial category, EXCEL has many other financial functions you can use,
most of which you should now be able to figure out on your own.
