Time Value of Money

Discussion Questions
9-1.            How is the future value (Appendix A) related to the present value of a single
sum (Appendix B)?

The future value represents the expected worth of a single amount, whereas the
present value represents the current worth.

9-2.            How is the present value of a single sum (Appendix B) related to the present
value of an annuity (Appendix D)?

The present value of a single amount is the discounted value for one future
payment, whereas the present value of an annuity represents the discounted
value of a series of consecutive future payments of equal amount.

9-3.            Why does money have a time value?

Money has a time value because funds received today can be invested to reach a
greater value in the future. A person would rather receive \$1 today than \$1 in
ten years, because a dollar received today, invested at 6 percent, is worth
\$1.791 after ten years.

9-4.            Does inflation have anything to do with making a dollar today worth more than
a dollar tomorrow?

Inflation makes a dollar today worth more than a dollar in the future. Because
inflation tends to erode the purchasing power of money, funds received today
will be worth more than the same amount received in the future.

Chapter 09: Time Value of Money

9-5.            Adjust the annual formula for a future value of a single amount at 12 percent
for 10 years to a semiannual compounding formula. What are the interest
factors (FVIF) before and after? Why are they different?

FV  PV  FVIF Appendix A 
i  12%, n  10        3.106 Annual
i  6%, n  20         3.207 Semiannual

The more frequent compounding under the semiannual compounding
assumption increases the future value so that semiannual compounding is worth
.101 more per dollar.

9-6.            If, as an investor, you had a choice of daily, monthly, or quarterly
compounding, which would you choose? Why?

The greater the number of compounding periods, the larger the future value.
The investor should choose daily compounding over monthly or quarterly.

9-7.            What is a deferred annuity?

A deferred annuity is an annuity in which the equal payments will begin at
some future point in time.

9-8.            List five different financial applications of the time value of money.

Different financial applications of the time value of money:

Equipment purchase or new product decision,
Present value of a contract providing future payments,
Future value of an investment,
Regular payment necessary to provide a future sum,
Regular payment necessary to amortize a loan,
Determination of return on an investment,
Determination of the value of a bond.

27.   Annuity due (LO4) As stated in the chapter, annuity payments are assumed to come at the
end of each payment period (termed an ordinary annuity). However, an exception occurs
when the annuity payments come at the beginning of each period (termed an annuity due).
To find the present value of an annuity due, subtract 1 from n and add 1 to the tabular
value. To find the future value of an annuity, add 1 to n and subtract 1 from the tabular
value. For example, to find the future value of a \$100 payment at the beginning of each
period for five periods at 10 percent, go to Appendix C for n = 6 and i = 10 percent. Look
up the value of 7.716 and subtract 1 from it for an answer of 6.716 or \$671.60 (\$100 ×
6.716).
What is the future value of a 10-year annuity of \$2,000 per period where payments
come at the beginning of each period? The interest rate is 8 percent.

9-27. Solution:
Appendix C
FVA = A × FVIFA
n = 11, i = 8%    16.645 – 1 = 15.645

period? The interest rate is 12 percent.

9-28. Solution:
Appendix D
PVA = A × PVIFA
n = 9, i = 12%       5.328 + 1 = 6.328
PVA = \$3,000 × 6.328 = \$18,984

29.   Present value alternative (LO3) Your grandfather has offered you a choice of one of the
three following alternatives: \$5,000 now; \$1,000 a year for eight years; or \$12,000 at the

36.   Solving for an annuity (LO4) Dr. Oats, a nutrition professor, invests \$80,000 in a piece of
land that is expected to increase in value by 14 percent per year for the next five years. She
will then take the proceeds and provide herself with a 10-year annuity. Assuming a 14
percent interest rate for the annuity, how much will this annuity be?

9-36. Solution:
Appendix A
FV = PV × FVIF (14%, 5 periods)
FV = \$80,000 × 1.925 = \$154,000

Appendix D
A = PVA/PVIFA (14%, 10 periods)
A = \$154,000/5.216 = \$29,524.54

37.   Solving for an annuity (LO4) You wish to retire in 20 years, at which time you want to
have accumulated enough money to receive an annual annuity of \$12,000 for 25 years after
retirement. During the period before retirement you can earn 8 percent annually, while
after retirement you can earn 10 percent on your money.
What annual contributions to the retirement fund will allow you to receive the \$12,000
annuity?

9-37. Solution:
Determine the present value of an annuity during retirement:
Appendix D
PVA  A  PVIFA (10%, 25 years)
 \$12,000  9.077  \$108,924

To determine the annual deposit into an account earning 8% that
is necessary to accumulate \$108,924 after 20 years, use the

38.   Deferred annuity (LO3) Rusty Steele will receive the following payments at the end of
the next three years: \$4,000, \$7,000, and \$9,000. Then from the end of the fourth year
through the end of the tenth year, he will receive an annuity of \$10,000. At a discount rate
of 10 percent, what is the present value of all future benefits?

9-38. Solution:
First find the present value of the first three payments.

PV = FV × PVIF (Appendix B) i = 10%

1) \$4,000 × .909 = \$3,636
2) 7,000 × .826 = 5,782
3) 9,000 × .751 = 6,759
\$16,177

Then find the present value of the deferred annuity.

Appendix D will give a factor for a seven period annuity (fourth
year through the tenth year) at a discount rate of 10 percent. The
value of the annuity at the beginning of the fourth year is:

PV A  A  PVIFA (10%,7 periods)
 \$10,000  4.868  \$48,680

This value at the beginning of year four (end of year three) must
now be discounted back for three years to get the present value of
the deferred annuity. Use Appendix B.

9-20
Chapter 09: Time Value of Money

PV  FV  PVIFA (10%,3periods)
 \$48,680  .751  \$36.559

Finally, find the total present value of all future payments.

Present value of first three payments                         \$16,177
Present value of the deferred annuity                          36,559

OR

Take the PVIFA for 10 years at 10% and subtract the PVIFA for 3
years at 10% to end up with the 7 year deferred annuity.

PVIFA = 6.145 (10 years at 10%)
PVIFA = 2.487 ( 3 years at 10%)
PVIFA = 3.658 (years 4 through 10 years at 10%)

\$10,000 × 3.658 = \$36,580

Present value of first three payments                \$16,177
Present value of the deferred annuity                 36,580

39.   Present value (LO3) Kelly Greene has a contract in which she will receive the following
payments for the next five years: \$3,000, \$4,000, \$5,000, \$6,000, and \$7,000. She will then
receive an annuity of \$9,000 a year from the end of the sixth through the end of the 15th
year. The appropriate discount rate is 13 percent. If she is offered \$40,000 to cancel the
contract, should she do it?

9-39. Solution:
First find the present value of the first five payments.
PV = FV × PVIF (Appendix B) i = 13%

9-21
Chapter 09: Time Value of Money

1) \$3,000 × .885 = \$ 2,655
2) 4,000 × .783 = 3,132
3) 5,000 × .693 = 3,465
4) 6,000 × .613 = 3,678
5) 7,000 × .543 = 3,801
\$16,731
Then find the present value of the deferred annuity.
Appendix D will give a factor for a ten period annuity (sixth year
through the fifteenth year) at a discount rate of 13 percent. The
value of the annuity at the beginning of the sixth year is:

PV A  A  PVIFA (13%, 10periods)
 \$9,000  5.426  \$48,834

This value at the beginning of year six (end of year five) must
now be discounted back for five years to get the present value of
the deferred annuity. Use Appendix B.
PV = FV × PVIF (13%, 5periods)
= \$48,834 ×.543 = \$26,517

9-39. (Continued)
Next, find the total present value of all future payments.

Present value of first three payments            \$16,731
Present value of the deferred annuity             26,517
\$43,248
Since the present value of all future benefits under the contract is
greater than \$40,000, Kelly Greene should not accept this amount
to cancel the contract.

40.   Deferred annuity (LO3) Kay Mart has purchased an annuity to begin payment at the end
of 2113 (the date of the first payment). Assume it is now the beginning of 2011. The
annuity is for \$12,000 per year and is designed to last eight years.
If the discount rate for the calculation is 11 percent, what is the most she should have paid
for the annuity?

9-40. Solution:
Appendix D will give a factor for an 8 year annuity when the
appropriate discount rate is 11 percent (5.146). The value of the
annuity at the beginning of the year it starts (2113) is:

PVA  A  PVIFA (11%, 8periods)
 \$12,000  5.146
 \$61,752

The present value at the beginning of 2011 is found using
Appendix B (2 years at 11%). The factor is .812. Note we are
discounting from the beginning of 2113 to the beginning of 2011.

PV = PV × PVIF (11%, 2periods)
= \$61,752 × .812
= \$50,142.62
The maximum that should be paid for the annuity is \$50,142.62.

41.   Yield (LO4) If you borrow \$9,725 and are required to pay back the loan in five equal
annual installments of \$2,500, what is the interest rate associated with the loan?

Appendix D

9-23
Chapter 09: Time Value of Money

PVIFA  PVA / A (5 periods)
 \$9,725/\$2,500

Interest rate = 9 percent

Go across period 5 until you find 3.890. Go up to the percentage
at the top of the column and find 9 percent.

42.   Loan repayment (LO4) Tom Busby owes \$20,000 now. A lender will carry the debt for
four more years at 8 percent interest. That is, in this particular case, the amount owed will
go up by 8 percent per year for four years. The lender then will require Busby to pay off the
loan over 12 years at 11 percent interest. What will his annual payment be?

9-42. Solution:
Appendix A
FV = PV × FVIFA (8%, 4periods)
FV = \$20,000 × 1.360
= \$27,200 Amount owed at end of 4 periods

Appendix D
A = PVA /PVIFA (11%, 12periods)

over the eight-year life of the loan, what equal annual payments must be made to discharge
the loan, plus pay the bank its required rate of interest (round to the nearest dollar)? How
much of his first payment will be applied to interest? To principal? How much of her
second payment will be applied to each?

9-43. Solution:

9-24
Chapter 09: Time Value of Money

Appendix D
A = PVA / PVIFA (10%, 8periods)
= \$50,000 / 5.335
= \$9,372.07 Annual payments

First payment:
\$50,000 × .10                      = \$5,000 first year interest
\$9,372.07 – \$5,000                 = \$4,372.07 applied to principal

Second payment: First determine remaining principal
\$50,000 – \$4,372.07     = \$45,627.93
\$45,627.93 × .10        = \$4,562.79 second year interest
\$9,372.07 – \$4,562.79 = \$4,809.28 applied to principal

44.   Loan repayment (LO4) Jim Thorpe borrows \$70,000 toward the purchase of a home at 12
percent interest. His mortgage is for 30 years.
a.   How much will his annual payments be? (Although home payments are usually on a
monthly basis, we shall do our analysis on an annual basis for ease of computation.
We will get a reasonably accurate answer.)
b.   How much interest will he pay over the life of the loan?
c.   How much should he be willing to pay to get out of a 12 percent mortgage and into a
10 percent mortgage with 30 years remaining on the mortgage? Suggestion: Find the
annual savings and then discount them back to the present at the current interest rate
(10 percent).

45.   Annuity with changing interest rates (LO4) You are chairperson of the investment fund
for the Continental Soccer League. You are asked to set up a fund of semiannual payments
to be compounded semiannually to accumulate a sum of \$200,000 after 10 years at an 8
percent annual rate (20 payments). The first payment into the fund is to take place six
months from today, and the last payment is to take place at the end of the 10th year.
a.    Determine how much the semiannual payment should be. (Round to whole numbers.)
On the day after the sixth payment is made (the beginning of the fourth year) the interest
rate goes up to a 10 percent annual rate, and you can earn a 10 percent annual rate on funds
that have been accumulated as well as all future payments into the fund. Interest is to be
compounded semiannually on all funds.
b.    Determine how much the revised semiannual payments should be after this rate
change (there are 14 payments and compounding dates). The next payment will be in
the middle of the fourth year. (Round all values to whole numbers.)

now 18 years old (five years have passed), and she wants to get married instead of going to
college. Your parents have accumulated the necessary funds for her education.
Instead of her schooling, your parents are paying \$10,000 for her current wedding and
plan to take year-end vacations costing \$3,000 per year for the next three years.
How much money will your parents have at the end of three years to help you with
graduate school, which you will start then? You plan to work on a master’s and perhaps a
PhD. If graduate school costs \$32,600 per year, approximately how long will you be able to

COMPREHENSIVE PROBLEM
Modern Weapons, Inc. (Comprehensive time value of money) Mr. Rambo, President of
Modern Weapons, Inc., was pleased to hear that he had three offers from major defense
companies for his latest missile firing automatic ejector. He will use a discount rate of 12 percent
to evaluate each offer.

9-31
Chapter 09: Time Value of Money

Offer I      \$500,000 now plus \$120,000 from the end of years 6 through 15. Also if the product
goes over \$50 million in cumulative sales by the end of year 15, he will receive an
additional \$1,500,000. Rambo thought there was a 75 percent probability this would
happen.
Offer II     Twenty-five percent of the buyer’s gross margin for the next four years. The buyer
in this case is Air Defense, Inc. (ADI). Its gross margin is 65 percent. Sales for year
1 are projected to be \$1 million and then grow by 40 percent per year. This amount
is paid today and is not discounted.
Offer III    A trust fund would be set up for the next nine years. At the end of that period,
Rambo would receive the proceeds (and discount them back to the present at
12 percent). The trust fund called for semiannual payments for the next nine years of
\$80,000 (a total of \$160,000 per year). The payments would start immediately. Since
the payments are coming at the beginning of each period instead of the end, this is
an annuity due. To look up the future value of the annuity due in the tables, add 1 to
n (18 + 1) and subtract 1 from the value in the table. Assume the annual interest rate
on this annuity is 12 percent annually (6 percent semiannually). Determine the
present value of the trust fund’s final value.
Required: Find the present value of each of the three offers and then indicate which
one has the highest present value.
