Question

Your retirement strategy is to invest 500 per month in an equity mutual fund and 200 per month in a bond fund. Your retirement date is 30 years from now. The expected return on the stock fund is expected to be 8% and the expected return on the bond fund is expected to be 3%. When you retire, you will combine your money into an account with an expected 5% return. How much can you withdraw each month from your account assuming a 25 year withdrawal period? At the end of the 25 years, the account value will be zero.

Explanation / Answer

We first find future value of nvestments.

We have 30 Yrs investmnet period with monthly PMT = 500 for MF & 200 for Bond

Equity MF :

FV(MF) = FV(rate,nper,pmt,pv)

= FV(8%/12,30*12,-500,0) = $745,180


Bond Fund :

FV(BF) = FV(rate,nper,pmt,pv)

= FV(3%/12,30*12,-200,0) = $116,547


So Total Corpus at end of 30 Yrs = EF+BF

= 745180 + $116,547

= $861,727


Now for next 25 Yrs, we have PV = $861,727, FV=0, Rate = 5%/12 & we need to find monthly withdrawl PMT

So Montly withdrawl = PMT(rate,nper,pv,fv)

= PMT(5%/12,25*12,861727,0)

= $5,037.57
