You are setting up your IRA. You have decided that you can afford to put $640 per month (end of each month) for 22 years into the account that is paying 9.4% compounded monthly. At the end of the 22 years, you would like to make annual withdrawals of $88,000 from the account, first withdrawal end of first retirement year (i.e., in 23 years) and you expect the account to pay 5.7% annual interest during this period, compounded annually. How many years into retirement before the retirement savings would run out? (Round your answer to 2 decimals)
