What This Calculator Does

Calculate your required minimum distribution (RMD) based on account balance and age.

It combines Account Balance (Dec 31 prior year), Your Age This Year, Estimated Tax Rate to estimate Required Minimum Distribution, Distribution Period, Monthly Equivalent.

Formula & Method

Core equations: Required minimum distribution uses the IRS Uniform Lifetime Table: RMD = \frac{B}{DP} where B is the account balance on Dec 31 of the prior year and DP is the distribution period for your age. Tax owed: T = RMD \times r_{tax} Inputs are applied in base units, then derived metrics are computed from the same equations and rounded for display.

Notation used in the formulas: R = Required Minimum Distribution; x_{1} = Account Balance (Dec 31 prior year); x_{2} = Your Age This Year; x_{3} = Estimated Tax Rate.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.

Inputs Used

  • Account Balance (Dec 31 prior year): Account balance as of December 31 of the prior year
