Suppose a man is

30
years old and would like to retire at age
60.
​Furthermore, he would like to have a retirement fund from which he can draw an income of
​$100,000
per
yearlong—​forever!
How can he do​ it? Assume a constant APR of
6%.

1 answer

since he want to have 100,000 "forever"
he will need a fund so that 6% of it = 100000
.06x = 100000
x = 1,666.666.67

so he has to accululate that much in 30 years, let the annual amount to save be P
P(1.06^30 - 1)/.06 = 1,666,666.67
P = 21,081.15 is needed each year
