Question

You are planning to save for retirement over the next 30 years. To save for retirement, you will invest $1,700 per month in a stock account in real dollars and $595 per month in a bond account in real dollars. The effective annual return of the stock account is expected to be 12 percent, and the bond account will have an annual return of 8 percent. When you retire, you will combine your money into an account with an effective annual return of 9 percent. The inflation rate over this period is expected to be 4 percent. How much can you withdraw each month from your account in real terms assuming a 25-year withdrawal period? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Monthly withdrawal What is the nominal dollar amount of your last withdrawal? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Last withdrawal $

Explanation / Answer

COnverting to nominal APRs with monthly compounding:
12%:=((1+12%)^(1/12)-1)*12=11.3866%
8%:=((1+8%)^(1/12)-1)*12=7.7208%
9%:=((1+9%)^(1/12)-1)*12=8.6488%

COnverting to real APRs:
12%:=(1+11.3866%)/(1+4%)-1=7.1025%
8%:=(1+7.7208%)/(1+4%)-1=3.5777%
9%:=(1+8.6488%)/(1+4%)-1=4.47%

Real AMount that can be withdrawn every month=PMT(4.47%/12,12*25,FV(7.1025%/12,12*30,1700)+FV(3.577%/12,12*30,595))=13851

Nominal amount of last withdrawl=13851*1.04^25=36924.49903
