You are planning for your retirement. Beginning in one year, you will contribute the first of 20 yearly after-tax dollar payments of $6,500 into your Roth Individual Retirement Account (IRA). After these payments, no more funds will be deposited or withdrawn until this date in 2056. If your expected rate of return is 8 percent, how much will your Roth IRA be worth in 2056?
