Colin is trying to decide whether he should make his IRA contribution at the beginning of the year or at the end of the year. He wants to save $5,000 per year for 25 years in his IRA that can earn 8% per year. What would be the difference in his account value if he made the payments at the beginning of each year rather than at the end?

Ans $ 29242
P = | Periodic payments |
r = | rate of interest |
n = | no of years |
IF PAYMENT MADE AFTER THE END OF THE YEAR | |
Future Value of Annuity = | P ( (1 + r)n - 1 ) / r |
5000* ((1 + 8%)^25 - 1) / (8%) | |
$ 365530 | |
IF PAYMENT MADE AT THE BEGINNING OF THE YEAR | |
Future Value of Annuity Due = | (1 + r) * P ( (1 + r)n - 1 ) / r |
(1 + 8%) * 5000* ((1 + 8%)^25 - 1) / (8%) | |
$ 394772 | |
DIFFERENCE OF FUTURE VALUE = | 394772 - 365530 |
$ 29242 | |
