i dont think that is right.
its an annuity problem, lookup your annuity formula
1. Paul plans to retire when he turns 55.
a. How much money will he need in his retirement investment so he can withdraw $40,000 per year for 30 years when he retires? Assume the interest rate in his reitrement years will be fixed at 8%, compounded annually.
b. Paul is 25 years old. How much does he need to save each year from now until he retires to fund his retirement plan? Assume the interest rate during his work years is fixed at 12%, compounded annually.
$40000 / 12 = 3333,333(a month)
A = P(1+i) exp n
P = 40000?
i = 0.08
n =30
A = 402, 506? Need feedback
Hello, terminator!
If you've been taught Compound Interest only,
. . you should not have been assigned this problem.
1. Paul plans to retire when he turns 55.
(a) How much money will he need in his retirement investment
so he can withdraw $40,000 per year for 30 years when he retires?
Assume the interest rate in his reitrement years will be 8%, compounded annually.
This is a Sinking Fund problem.
Formula: .
. . where: .
We have: .
Hence: .
At age 55, Paul will need
. . . Note that I rounded up. .(Why?)
(b) Paul is 25 years old. .How much does he need to save each year
from now until he retires to fund his retirement plan?
Assume the interest rate during his work years is 12%, compounded annually.
SpringFan25 is correct . . . This is an Annuity problem.
Formula: .
. . where: .
We have: .
Hence: .
Until his retirement, Paul must save each year.
