Suppose that at time 20 you will receive a retirement bonus of $50,000 from your company. If the annual percentage rate (APR) is expected to be 6 percent, compounded monthly, from now until time 20, how much would you need to save at the end of each month in order to be able to make the desired withdrawals at retirement (i.e., in order to have $1,276,935.35, including the bonus, saved at time 20)?
