Question
You are planning to save for retirement over the next 25 years. To do this, you will invest $700 per month in a stock account and $300 per month in a bond account. The return of the stock account is expected to be an APR of 9 percent, and the bond account will earn an APR of 5 percent. When you retire, you will combine your money into an account with an APR of 6 percent. All interest rates are compounded monthly. How much can you withdraw each month from your account assuming a withdrawal period of 20 years? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Withdrawal $ 6910.13 (incorrect)per month
Explanation / Answer
Monthly Withdrawl $ 6,902.45 per month Working: a. Future Value of annuity of 1 @ 9% = (((1+i)^n)-1)/i Where, = (((1+0.0075)^300)-1)/0.0075 i 9%/12 = 0.0075 = 1121.1219 n 25*12 = 300 b. Future Value of Stock Investment = Monthly investment x Future Value of annuity of 1 = $ 700.00 x 1121.1219 = $ 7,84,785.36 c. Future Value of annuity of 1 @ 5% = (((1+i)^n)-1)/i Where, = (((1+0.004167)^300)-1)/0.004167 i 5%/12 = 0.004167 = 595.5453 n 25*12 = 300 d. Future Value of Bonds Investment = Monthly investment x Future Value of annuity of 1 = $ 300.00 x 595.5453 = $ 1,78,663.58 e. Combined Future Value of Investment = $ 7,84,785.36 + $ 1,78,663.58 = $ 9,63,448.94 f. Present value of annuity of 1 @ 6% = (1-(1+i)^-n)/i Where, = (1-(1+0.005)^-240)/0.005 i 6%/12 = 0.005 = 139.5808 n 20*12 = 240 g. Amount of monthly withdrawl = Total Accumulated amount at the beginning of withdrawl period/Present value of annuity of 1 = $ 9,63,448.94 / 139.5808 = 6,902.45
