Suppose you will deposit $500 per month for 10 years with the first payment occurring at the end of the current month (i.e., one month from today and the final deposit 10 years from today). Assume that you will begin withdrawing funds in level annual amounts at year 21 and that you will make 10 annual withdrawals of $35,000 (i.e., the first withdrawal is at 21 with subsequent withdrawals each year), You will also make a second stream of level quarterly deposits for 10 years with the first deposit occurring 3 months after year 10 (or at time 10.25) and the last at time 20. How much will you need to deposit in this second stream to cover your subsequent withdrawals if the EAR is 5.1162%
