Formula & Theory - RMD Calculator
The RMD Calculator uses these formulas:
Annual RMD = Prior Year-End Balance ÷ Distribution Factor
Monthly Equivalent = Annual RMD ÷ 12
| Symbol | Meaning |
|---|---|
| Prior Year-End Balance | The account balance on December 31 of the previous year |
| Distribution Factor | Life expectancy factor from the Uniform Lifetime Table |
| Annual RMD | Minimum amount required to withdraw this year |
Assumptions and Limits
The RMD Calculator uses the Uniform Lifetime Table. It does not handle multiple accounts (must aggregate balances), inherited IRAs, or beneficiary RMDs. RMDs missed by the deadline may face a 25% excise tax (10% if corrected timely).
