Inherited Roth Ira Rmd Calculator

When you inherit a Roth IRA, the IRS has specific rules about how and when you must withdraw funds, known as Required Minimum Distributions (RMDs). These rules depend on your relationship to the original account owner, your age, and the method of distribution you choose.

How the Inherited Roth IRA RMD Calculator Works

This tool is designed for beneficiaries of Roth IRAs who need to determine their first-year required minimum distribution and get a suggested annual withdrawal amount.

It supports two main calculation methods:

  1. 10-Year Rule – You must fully withdraw the account within 10 years of the original owner’s death. This method in our calculator uses equal annual withdrawals for simplicity.
  2. Life Expectancy Method – Uses the IRS Single Life Expectancy Table to determine annual withdrawals over your lifetime, starting in the year after the original owner’s death.

Step-by-Step Instructions

  1. Enter the Account Balance
    • Type in the total balance of the inherited Roth IRA.
    • Use whole numbers or decimals (e.g., 250000 or 250000.75).
  2. Choose the Distribution Method
    • 10-Year Rule – No need to enter your age.
    • Life Expectancy Method – You’ll need to provide your age in the year after the original owner’s death.
  3. (If Applicable) Enter the Beneficiary Age

  5. View Results and Notes
    • For the Life Expectancy Method, the calculator displays a reminder that the divisor decreases by one each year.
  6. Reset if Needed
    • Click “Reset” to clear all fields and start over.
