You just graduated from college and are starting your new job. You realized the importance to save for the future and have figured out that you will save $3,000 per month for the next 12 years; and then increase to $7,000 per month for the following 6 years. The amount accumulated at the end of these investments will be your retirement egg nest. You plan to start retirement and start withdrawing monthly amounts the following month (you will be in retirement for 21 years). If your required rate of return is 12% compounded monthly, how much are your monthly withdrawals?
