If I hired you to work for me when you graduate paid you roughly $40,000 a year and together you ended up with $5,000 a year in your 401K for 5 years before you found out I was underpaying you and you left. Your 401K had that money and earned 7% a year for 35 years and your fees totaled about 1/2% and you never put any more money into it. How much would you have upon retirement?
FV of annuity | ||
The formula for the future value of an ordinary annuity, as opposed to an annuity due, is as follows: | ||
P = PMT x ((((1 + r) ^ n) - 1) / r) | ||
Where: | ||
P = the future value of an annuity stream | To be computed | |
PMT = the dollar amount of each annuity payment | 5000 | |
r = the effective interest rate (also known as the discount rate) | 6.50% | 7%-0.5% |
n = the number of periods in which payments will be made | 5 | |
Corpus value after 5 years= | PMT x ((((1 + r) ^ n) - 1) / r) | |
Corpus value after 5 years= | 5000* ((((1 + 6.5%) ^ 5) - 1) / 6.5%) | |
Corpus value after 5 years= | $ 28,468.20 | |
Now this corpus remains invested for next 30 years so crpus after next 35 years= | 28468.20*(1+6.5%)^30 | |
Now this corpus remains invested for next 30 years so crpus after next 35 years= | $188,299.10 | |
