Non-Spouse Inherited IRA RMD Calculator
Required Minimum Distribution (RMD)

Understanding Non-Spouse Inherited IRA RMDs
When an IRA owner passes away, their beneficiaries may inherit the IRA. For beneficiaries who are not the surviving spouse, special rules apply regarding Required Minimum Distributions (RMDs). These rules ensure that the inherited tax-deferred funds are eventually distributed and taxed.
Who is a Non-Spouse Beneficiary?
A non-spouse beneficiary includes anyone inheriting an IRA who is not the deceased owner's spouse. This can be children, grandchildren, friends, or other individuals or entities. The rules for non-spouse beneficiaries differ significantly from those for surviving spouses.
The Required Minimum Distribution (RMD)
RMDs are mandatory withdrawals that individuals must take from their retirement accounts once they reach a certain age. For inherited IRAs, the RMD rules are designed to start distributions to the beneficiary. The calculation depends on several factors, primarily the beneficiary's age and the IRS life expectancy tables.
Calculating the Non-Spouse Inherited IRA RMD
The calculation involves determining the account balance as of December 31st of the year preceding the distribution and dividing it by the applicable life expectancy factor from the IRS. For non-spouse beneficiaries, the most common method is to use the IRS's Uniform Lifetime Table or, if the beneficiary is more than 10 years younger than the IRA owner, the Single Life Expectancy Table.
However, a critical rule for non-spouse beneficiaries is the 10-Year Rule, which applies to deaths occurring on or after January 1, 2020. Under this rule, the entire inherited IRA balance must be distributed by December 31st of the tenth year following the IRA owner's death. If the beneficiary is required to take annual RMDs during this 10-year period, they must do so. If they are not required to take annual RMDs (e.g., they are younger than the age when RMDs are typically required), they still must distribute the entire balance by the end of the 10th year.
This calculator primarily focuses on the annual RMD calculation. It uses the beneficiary's age to find the appropriate life expectancy factor from the IRS's Uniform Lifetime Table (which is also used for single beneficiaries in most cases where the 10-year rule is not the primary driver for the *current year's* RMD). Note that for deaths before 2020, different rules and tables might have applied.
The Math Behind the Calculation:
- Determine the IRA Account Balance: This is the account's value as of December 31st of the year *prior* to the year for which you are calculating the RMD.
- Determine the Beneficiary's Age: The age used is the beneficiary's age during the calendar year for which the RMD is being calculated.
- Find the Life Expectancy Factor: Consult the IRS Publication 590-B, Appendix A, for the relevant life expectancy table. For non-spouse beneficiaries, the Uniform Lifetime Table is generally used for annual RMDs. If the beneficiary is more than 10 years younger than the deceased IRA owner, they can elect to use the Single Life Expectancy Table, which can result in a smaller RMD. This calculator uses the Uniform Lifetime Table.
- Calculate the RMD:
RMD = (Account Balance on Dec 31st of Prior Year) / (Life Expectancy Factor)
Example Scenario
Let's say John inherits his mother's IRA. His mother passed away in 2023. The IRA had a balance of $500,000 on December 31, 2023. John was born on June 15, 1965. He will be 59 years old for most of 2024.
- Account Balance: $500,000
- Beneficiary's Age in 2024: 59
- Life Expectancy Factor for age 59 (from Uniform Lifetime Table): 25.3
John's RMD for 2024 would be:
$500,000 / 25.3 = $19,762.85 (approximately)
Important Note on the 10-Year Rule: For non-spouse beneficiaries inheriting an IRA due to the owner's death on or after January 1, 2020, the entire account must be distributed by the end of the 10th year following the owner's death. This calculator provides the *annual* RMD if applicable, but beneficiaries must also be mindful of completing full distribution by the end of the 10-year period.
