Andrew has purchased a new car He wishes to set aside enough
Andrew has purchased a new car. He wishes to set aside enough money in a bank account to pay the maintenance for the first 5 years. It has been estimated that the maintenance cost of a car is as follows: Year Maintenance Cost $120 $150 $180 $210 $240 2 4 Assume the maintenance costs occur at the end of each year and that the bank pays 5% interest. How much should Andrew deposit in the bank now?

Solution
This is the calculation of present value (PV) by the discount rate of 5%.
Year
Cost = C
5% factors (F) = 1/(1 + 0.05)^n [where n = number of years]
C × F
1
120
0.95238
114.29
2
150
0.90702
136.05

0.78352
188.04
PV
766.64
Answer: The deposited amount should be $766.64.
| Year | Cost = C | 5% factors (F) = 1/(1 + 0.05)^n [where n = number of years] | C × F |
| 1 | 120 | 0.95238 | 114.29 |
| 2 | 150 | 0.90702 | 136.05 |
| 3 | 180 | 0.86383 | 155.49 |
| 4 | 210 | 0.82270 | 172.77 |
| 5 | 240 | 0.78352 | 188.04 |
| PV | 766.64 |
