IRA/401(k)/403(b) Retirement Calculation

Updated October 1997 - Require minimum withdrawals using IRS life expectancy table. At 70 1/2 you are forced to withdraw the minimum. Also now adds 10% withdrawal penalty for before 59 1/2.

Since the mortgage calcuator is so popular, I put together a form that does another calculation I find important, finding out how much to put away tax deferred to get a certain amount of money in the future, and how much you could expect to draw out of that money. Just put in some numbers to see what I am talking about!


Beginning Balance of Account
Monthly contribution
Current Age
Years until retirement
Estimated annual pre-retirement yield (%)
Estimated annual retirement yield (%)
Estimated annual inflation (%)
Estimated annual contribution increase(%)
Desired future monthly withdrawal amount (current dollars)
