You are planning to save for retirement over the next 20 years. To do this, you will invest $1,300 a month in a stock account and $1,000 a month in a bond account. The return of the stock account is expected to be 8 percent, and the bond account will pay 5 percent. When you retire, you will combine your money into an account with a return of 6 percent. How much can you withdraw each month from your account assuming a 25-year withdrawal period?
