The insurance company which manages the retirement fund promises to pay a stated (or nominal) rate of 12% per year, but with quarterly compounding. if your mother invests $1000 each six months, starting 18 months from today, how much will she have 5 years from now, assuming the last payment is made at the end of year 5?
Draw the time lines for all the problems and show all the formulas/equations.
Time Period | Investment value | Interst rate multiplier | Calculation of multiplier | Amount |
0 | $ - | |||
6 | $ - | |||
12 | $ - | |||
18 | $ 1,000.00 | 11.9764 | (1.03), 84 times | $ 11,976.42 |
24 | $ 1,000.00 | 8.4000 | (1.03), 72 times | $ 8,400.02 |
30 | $ 1,000.00 | 5.8916 | (1.03), 60 times | $ 5,891.60 |
36 | $ 1,000.00 | 4.1323 | (1.03), 48 times | $ 4,132.25 |
42 | $ 1,000.00 | 2.8983 | (1.03), 36 times | $ 2,898.28 |
48 | $ 1,000.00 | 2.0328 | (1.03), 24 times | $ 2,032.79 |
54 | $ 1,000.00 | 1.4258 | (1.03), 12 times | $ 1,425.76 |
60 | $ 1,000.00 | 1.0000 | (1.03), 0 times | $ 1,000.00 |

The given rate of interest is 12% , which is compounded quarterly. Then interest rate each quarter will be 3% |
Formula using the problem is so just Instalment value * Interest rate multiplier which is compunded quarterly
For Ex. first installment paid on 18 months so the period for which interest compounded is 84 quarters.
