Time Value of Money

Problems

1. Future value (LO2) You invest $2,500 a year for three years at 8 percent.

a. What is the value of your investment after one year? Multiply $2,500 × 1.08.

b. What is the value of your investment after two years? Multiply your answer to part a by 1.08.

c. What is the value of your investment after three years? Multiply your answer to part b by 1.08. This gives your final answer.

d. Confirm that your final answer is correct by going to Appendix A (future value of $1), and looking up the future value for n = 3, and i = 8 percent. Multiply this tabular value by $2,500 and compare your answer to the answer in part c. There may be a slight difference due to rounding.

9-1. Solution:

a. $2,500 × 1.08 = $2,700

b. $2,700 × 1.08 = $2,916

c. $2,916 × 1.08 = $3,149.28

d. Appendix A (8%, 3 periods)

FV = PV × FVIF

$2,500 × 1.260 = $3,150

2. Present value (LO3) What is the present value of:

a. $8,000 in 10 years at 6 percent?

b. $16,000 in 5 years at 12 percent?

c. $25,000 in 15 years at 8 percent?

Solution:

3. Present Value (LO3)

a. What is the present value of $100,000 to be received after 40 years with an 18 percent discount rate?

b. Would the present value of the funds in part a be enough to buy a $125 concert ticket?

Solution:

Appendix B

PV = FV × PVIF (18%, 40 periods)

a. $100,000 × .001 = $100

b. NO. You only have $100 in present value.

4. Present Value (LO4) You will receive $4,000 three years from now. The discount rate is 10 percent.

a. What is the value of your investment two years from now? Multiply $4,000 × .909 (one year’s discount rate at 10 percent).

b. What is the value of your investment one year from now? Multiply your answer to part a by .909 (one year’s discount rate at 10 percent).

c. What is the value of your investment today? Multiply your answer to part b by .909 (one year’s discount rate at 10 percent).

d. Confirm that your answer to part c is correct by going to Appendix B (present value of $1) for n = 3 and i = 10%. Multiply this tabular value by $4,000 and compare your answer to part c. There may be a slight difference due to rounding.

9-4. Solution:

5. Future value (LO2) If you invest $12,000 today, how much will you have:

a. In 6 years at 7 percent?

b. In 15 years at 12 percent?

c. In 25 years at 10 percent?

d. In 25 years at 10 percent (compounded semiannually)?

9-5. Solution:

Appendix A

a. $12,000 × 1.501 = $ 18,012

b. $12,000 × 5.474 = $ 65,688

c. $12,000 × 10.835 = $130,020

d. $12,000 × 11.467 = $137,604 (5%, 50 periods)

6. Present value (LO3) Your aunt offers you a choice of $20,000 in 50 years or $45 today. If money is discounted at 13 percent, which should you choose?

9-6. Solution:

7. Present Value (LO3) Your uncle offers you a choice of $100,000 in 10 years or $45,000 today. If money is discounted at 8 percent, which should you choose?

9-7. Solution:

Appendix B

PV = FV × PVIF (8%, 10 periods)

PV = $100,000 × .463 = $46,300

Choose $100,000 after 10 years.

8. Present Value (LO3) In Problem 7, if you had to wait until 12 years to get the $100,000, would your answer change? All other factors remain the same.

9-8. Solution:

9-9. Solution:

Appendix B

EMBED Equation.DSMT4

The difference is $17,200

9-10. Solution:

11. Future value (LO2) If you invest $8,000 per period for the following number of periods, how much would you have?

a. 7 years at 9 percent.

b. 40 years at 11 percent.

9-11. Solution:

Appendix C

FVA = A × FV IFA

a. $8,000 × 9.20 = $ 73,600

b. $8,000 × 581.83 = $ 4,654,640

12. Future value (LO2) You invest a single amount of $12,000 for 5 years at 10 percent. At the end of 5 years you take the proceeds and invest them for 12 years at 15 percent. How much will you have after 17 years?

9-12. Solution:

13. Present value (LO3) Mrs. Crawford will receive $6,500 a year for the next 14 years from her trust. If a 8 percent interest rate is applied, what is the current value of the future payments?

9-13. Solution:

Appendix D

PVA = A × PVIFA (8%, 14 periods)

= $6,500 × 8.244 = $53,586

14. Present value (LO3) John Longwaite will receive $100,000 in 50 years. His friends are very jealous of him. If the funds are discounted back at a rate of 14 percent, what is the present value of his future “pot of gold”?

9-14. Solution:

15. Present Value (LO3) Sherwin Williams will receive $18,000 a year for the next 25 years as a result of a picture he has painted. If a discount rate of 10 percent is applied, should he be willing to sell out his future rights now for $160,000?

9-15. Solution:

Appendix D

PVA = A × PVIFA (10%, 25 periods)

PVA = $18,000 × 9.077 = $163,386

No, the present value of the annuity is worth more than $160,000.

16. Present value (LO3) General Mills will receive $27,500 per year for the next 10 years as a payment for a weapon he invented. If a 12 percent rate is applied, should he be willing to sell out his future rights now for $160,000?

9-16. Solution:

17. Present value (LO3) The Western Sweepstakes has just informed you that you have won $1 million. The amount is to be paid out at the rate of $50,000 a year for the next 20 years. With a discount rate of 12 percent, what is the present value of your winnings?

9-17. Solution:

Appendix D

PVA = A × PVIFA (12%, 20 periods)

PVA = $50,000 × 7.469 = $373,450

18. Present value (LO3) Rita Gonzales won the $60 million lottery. She is to receive $1 million a year for the next 50 years plus an additional lump sum payment of $10 million after 50 years. The discount rate is 10 percent. What is the current value of her winnings?

19. Future value (LO2) Bruce Sutter invests $2,000 in a mint condition Nolan Ryan baseball card. He expects the card to increase in value 20 percent a year for the next five years. After that, he anticipates a 15 percent annual increase for the next three years. What is the projected value of the card after eight years?

9-19. Solution:

Appendix A

FV = PV × FVIF (20%, 5 periods)

= $2,000 × 2.488 = $4,976

FV = PV × FVIF (15%, 3 periods)

= $4,976 × 1.521 = $7,568.50

20. Future value (LO2) Christy Reed has been depositing $1,500 in her savings account every December since 2001. Her account earns 6 percent compounded annually. How much will she have in December 2010? (Assume that a deposit is made in December of 2010. Make sure to count the years carefully.)

9-20. Solution:

21. Future value (LO2) At a growth (interest) rate of 8 percent annually, how long will it take for a sum to double? To triple? Select the year that is closest to the correct answer.

9-21. Solution:

Appendix A

If the sum is doubling, then the tabular value must equal 2.

In Appendix A, looking down the 8% column, we find the factor closest to 2 (1.999) on the 9-year row. The factor closest to 3 (2.937) is on the 14-year row.

22. Present value (LO3) If you owe $30,000 payable at the end of five years, what amount should your creditor accept in payment immediately if she could earn 11 percent on her money?

9-22. Solution:

23. Present value (LO3) Barney Smith invests in a stock that will pay dividends of $3.00 at the end of the first year; $3.30 at the end of the second year; and $3.60 at the end of the third year. Also, he believes that at the end of the third year he will be able to sell the stock for $50. What is the present value of all future benefits if a discount rate of 11 percent is applied? (Round all values to two places to the right of the decimal point.)

9-23. Solution:

Appendix B

PV = FV × PVIF

Discount rate = 11%

$ 3.00 × .901 = $ 2.70

3.30 × .812 = 2.68

3.60 × .731 = 2.63

50.00 × .731 = 36.55
