How the Inherited IRA RMD Calculator Works
Inherited IRA distribution rules depend heavily on your relationship to the original account owner. This calculator estimates your RMD under the life expectancy method, the 10-year rule, or the 5-year rule, depending on your beneficiary type.
This inherited IRA RMD calculator computes:
- Applicable Life Expectancy Factor — from the IRS Single Life Expectancy Table (approximate)
- Estimated Current Year RMD — your required withdrawal this year
- RMD as % of Balance — the proportion of the account required to be withdrawn
- Full Distribution Deadline — when the entire account must be depleted
Inherited IRA RMD Formula
Life Expectancy Method (Spouse & Eligible Designated Beneficiaries)
RMD = Account Balance ÷ Life Expectancy Factor
For non-spouse eligible designated beneficiaries, the factor is set in the first distribution year and reduced by 1 for each subsequent year (not re-looked-up from the table).
10-Year Rule / 5-Year Rule
These rules generally require the entire account to be emptied by the end of the applicable year, with annual RMDs potentially required during the 10-year window if the original owner had already begun taking RMDs.

Frequently Asked Questions
What is an inherited IRA RMD?
An inherited IRA RMD (Required Minimum Distribution) is the minimum amount a beneficiary must withdraw each year from an inherited retirement account, with the calculation method depending on the beneficiary’s relationship to the original owner and other factors.
What is the 10-year rule for inherited IRAs?
Under the SECURE Act, most non-spouse beneficiaries who are not “eligible designated beneficiaries” must fully distribute the inherited IRA within 10 years of the original owner’s death, and may also owe annual RMDs during that period if the original owner had already started taking RMDs.
Who qualifies as an eligible designated beneficiary?
Eligible designated beneficiaries include surviving spouses, minor children of the account owner (until they reach the age of majority), disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the account owner. They can generally use the life expectancy method instead of the 10-year rule.
What happens if I don’t take my RMD?
Failing to take a required RMD can result in an IRS excise tax penalty on the amount not withdrawn, though this penalty has been reduced under SECURE 2.0 if corrected in a timely manner.
