This calculator can be used to determine your Required Minimum Distribution (RMD) from a traditional 401(k) or IRA. In general, you must begin withdrawing money by April 1st of the year following the year that you turn 70½. In general, your age and account value determine the amount you must withdraw. Note that taxes may be due on distributions from a traditional IRA or 401(k). Do not include balances from a Roth IRA or Roth 401(k) when using this calculator. This calculator is not designed to work for beneficiary (inherited) IRAs. That capability may be added in a forthcoming update.
