How much must you save annually, beginning 1 year from now, in order to accumulate $2,500,000 by the end of 35 years to cover your living expenses in retirement? Assume the funds in your IRA earn 10% annually. Also, how much total interest has been earned on your savings? Note: This problem is the future value of an ordinary annuity (FVAord) and I am asking you to find the annual PMT (or C as our authors note in the text). Finally, please round your answer to the nearest whole dollar ($1).
Annual Payments (PMT, of C)=
Total Interest Earned =
Future Value (F.V.) required = $2,500,000
Time period (n) = 35 years
Interest rate (r) = 10%
Let the Annual Annuity be to be beginning year 1 from now be "PMT"
Step 1 : Calculation of Annuity
Formula for Future Value of Annuity
2500000 = PMT ((1+0.10)35 -1) / 0.10
2500000 = PMT (28.1024368 -1) / 0.10
2500000 = PMT* 27.1024368 / 0.10
2500000 = PMT* 271.024368
PMT = $9224.26
Annual Payments (PMT or C) = $9,224.26
Step 2 : Calculation of Interest earned
Total amount of Principal invested for 35 years = Annuity *35 years = $9224.26 *35 = $322,849.20
Total Interest earned = Future value - Total Principal Invested
= $2,500,000 - 322,849.20
= $2,177,150.80
Total Interest Earned = $2,177,150.80
