How to Calculate Present Values

1.If the discount factor is .507, then .507*1.126 = \$1

2.125/139 = .899

3. PV = 374/(1.09)9 = 172.20

4. PV = 432/1.15 + 137/(1.152) + 797/(1.153) = 376 + 104 + 524 = \$1,003

5.FV = 100*1.158 = \$305.90

6. NPV = -1,548 + 138/.09 = -14.67 (cost today plus the present value of the perpetuity)

7.PV = 4/(.14-.04) = \$40

8.a. PV = 1/.10 = \$10

b. Since the perpetuity will be worth \$10 in year 7, and since that is roughly
double the present value, the approximate PV equals \$5.
PV = (1 / .10)/(1.10)7 = 10/2= \$5 (approximately)

c. A perpetuity paying \$1 starting now would be worth \$10, whereas a perpetuity starting in year 8 would be worth roughly \$5. The difference between these cash flows is therefore approximately \$5. PV = 10 – 5= \$5 (approximately)

d. PV = C/(r-g) = 10,000/(.10-.05) = \$200,000.

9. a. PV = 10,000/(1.055) = \$7,835.26 (assuming the cost of the car does not appreciate over those five years).

b. You need to set aside (12,000 × 6-year annuity factor) = 12,000 × 4.623 =
\$55,476.

c. At the end of 6 years you would have 1.086 × (60,476 - 55,476) = \$7,934.

11. Same as 10.
