Jack and Jill need to save $7000 toward a new car. How long will it take them if they save $330 a month earning interest at 6.5% per year? (Treat as an ordinary annuity.) (State your answer in years rounded to the second decimal place, e.g., 12.34)
Number of payments required to achieve future value | = | log [(FV × r/ PMT) +1] /log(1+r) | |
Future value | FV | 7,000.00 | |
Rate per period | r | ||
Annual interest | 6.5% | ||
Number of payments per year | 12 | ||
Interest rate per period | 0.065/12= | ||
Interest rate per period | 0.542% | ||
Payment per period | PMT | $ 330.00 | |
Number of payments | = | log [( 7000×0.00542/330) +1]/ long(1+ 0.00542) | |
= | 20.13 | ||
Years | 1.68 |
Answer is:
1.68
