An IRA is a retirement account that you may withdraw starting at age 60. Financial advisors suggest that you only withdraw 5% a year. If you had $100,000 on that account, at what age would you run out of money?

Pretty lousy account if it does not accrue interest. Anyway, just look up your formula for annuities, and plug in your numbers.
