RMD Calculator: Estimate Your Required Minimum Distribution
Use this RMD calculator to estimate your required minimum distribution (RMD) from a Traditional IRA, 401(k), 403(b), or eligible 457(b) based on IRS life expectancy tables and your prior year-end account balance. The calculator applies the current IRS age rules, determines the appropriate life expectancy factor, and estimates the minimum amount you must withdraw for the selected calculation year.
Sum manually if aggregating multiple Traditional IRAs — this build doesn't aggregate automatically.

Projection model: The RMD amount and any projected future distributions shown above are based on the information you entered. Current-year RMD calculations use applicable IRS life expectancy tables and distribution rules, while future projections assume a fixed annual rate of return and are not adjusted for inflation, taxes, investment fees, or future changes in IRS regulations. These results are hypothetical and provided for illustrative purposes only. Consult a qualified tax professional or financial advisor before making retirement distribution decisions.
What Is an RMD Calculator?
A Required Minimum Distribution (RMD) calculator is a retirement planning tool that estimates the minimum amount you must withdraw annually from tax-deferred accounts, including Traditional IRAs, SEP IRAs, SIMPLE IRAs, 401(k)s, 403(b)s, and eligible governmental 457(b) plans, once you reach the IRS-required distribution age. It uses your prior year-end account balance, your age, and the applicable IRS life expectancy factor to determine your required withdrawal.
This tool estimates your current-year RMD and projects future distributions based on IRS life expectancy tables and your selected assumptions. Results are estimates and may not reflect inherited account rules or unique beneficiary situations. Always confirm your required distribution with your plan administrator or a qualified tax professional before taking withdrawals.
How Does This Calculator Determine Your RMD?
This RMD calculator follows IRS distribution rules to estimate your required minimum distribution. It first selects the appropriate IRS life expectancy table based on your retirement account and beneficiary information. It then calculates your current-year RMD using your prior year-end account balance and the applicable life expectancy factor. If you enable projections, the calculator estimates future account balances and annual RMDs using your assumed annual rate of return.
RMD = Prior Year-End Account Balance ÷ IRS Life Expectancy Factor
Ending Balance = (Beginning Balance × (1 + Annual Rate of Return)) − Annual RMD
Future RMD = Projected Prior Year-End Balance ÷ Updated IRS Life Expectancy Factor
The calculator also updates the life expectancy factor each projection year according to the applicable IRS table and rounds displayed values based on standard financial rounding rules. Future projections are hypothetical and do not account for taxes, inflation, investment fees, additional contributions, or future changes to IRS regulations.

What You'll Need to Use This Calculator?
To use this RMD calculator, you will need your date of birth, prior year-end account balance, calculation year, beneficiary information, and your spouse's date of birth (if applicable).
Date of birth (account owner)
Enter your date of birth so the calculator can determine your age during the selected distribution year and apply the correct IRS life expectancy factor.
Whether a spouse is the sole primary beneficiary
Indicate whether your spouse is your only primary beneficiary. If applicable, the calculator determines whether a different IRS life expectancy table should be used.
Account balance
Provide your retirement account balance as of December 31 of the previous year. This is the balance the IRS requires for calculating your current year's RMD.
Spouse's date of birth (if applicable)
If your spouse is the sole primary beneficiary, enter their date of birth. The calculator compares your ages to determine whether the IRS Joint Life and Last Survivor Expectancy Table applies.
Calculation year
Select the year for which you want to calculate your required minimum distribution. The calculator uses the IRS rules and life expectancy tables applicable to that year.
What Are the Factors That Determine Your RMD Result?
Factors such as your age, prior year-end account balance, birth year, beneficiary information, and the applicable IRS life expectancy table determine your required minimum distribution (RMD). The calculator evaluates each of these factors to estimate the minimum amount you must withdraw for the selected distribution year.
Age in the calculation year
Your age during the selected distribution year determines which life expectancy factor the IRS assigns to you. This factor is one of the primary inputs used to calculate your required minimum distribution.
Account balance as of December 31, prior year
The calculator uses your retirement account balance as of December 31 of the previous year, since IRS regulations require this balance to determine your current year's RMD.
Birth-year tier
Your birth year determines the age at which you are required to begin taking RMDs. The calculator uses this information to apply the correct IRS starting-age rules for the selected calculation year.
Spouse's status as sole primary beneficiary
If your spouse is your only primary beneficiary, the calculator checks whether you qualify to use the IRS Joint Life and Last Survivor Expectancy Table instead of the Uniform Lifetime Table.
Spouse's age, if applicable
When your spouse is the sole primary beneficiary, their age is compared with yours. If your spouse is more than 10 years younger, different IRS life expectancy factors may apply, which can reduce your required minimum distribution.
Life expectancy table selected (Uniform Lifetime or Joint Life)
Based on your age and beneficiary information, the calculator selects either the Uniform Lifetime Table or the Joint Life and Last Survivor Expectancy Table to determine the appropriate life expectancy factor.
Life expectancy factor for the applicable age
Each IRS life expectancy table assigns a factor based on the applicable age. The calculator divides your prior year-end account balance by this factor to calculate your required minimum distribution.
Rounding convention applied to the final figure
After completing the calculation, the estimated RMD is rounded using standard financial rounding conventions, providing a clear and consistent result for reporting and planning purposes.
How This Calculator Rounds Your RMD
This RMD calculator rounds your required minimum distribution up to the next whole dollar while maintaining precise calculations throughout the process. This approach helps reduce the risk of under-withdrawing your required minimum distribution.
-
Rounds up to the next whole dollar, never down
Once your RMD is calculated using the applicable IRS life expectancy factor, the final withdrawal amount is always rounded up to the next whole dollar. For example, an RMD of $12,450.01 is displayed as $12,451.
-
Prevents an IRS under-distribution penalty
Withdrawing less than your required minimum distribution can result in an IRS excise tax if the shortfall is not corrected. By rounding upward, the calculator helps minimize the possibility of an under-distribution caused by rounding down.
-
Applies to every year in a projection
When generating multi-year RMD projections, the calculator applies the same rounding methodology to each projected annual distribution, ensuring consistent estimates throughout the projection period.
-
Tracks your balance to the exact cent
Although the displayed RMD is rounded to a whole dollar, all underlying calculations, including annual investment growth, account balances, and future RMD estimates, are performed using exact cent-level precision before the final rounding step.
-
Reflects Imeson's firm policy, not an IRS rule
The rounding method used by this calculator is Imeson's internal calculation policy, adopted to provide conservative and consistent estimates. The IRS does not require taxpayers to round every RMD up to the next whole dollar, so you should follow your plan administrator's or tax professional's guidance when taking actual distributions.
What Are the Limitations of Our RMD Calculator?
This RMD calculator provides estimates based on the information you enter and current IRS distribution rules, but it does not account for every retirement or tax situation. The following limitations may affect the accuracy or applicability of your results.
-
Results Depend on Your Inputs: The calculator assumes all information you enter, including your age, account balance, beneficiary details, and projection assumptions, is complete and accurate. Incorrect or incomplete inputs will produce inaccurate estimates.
-
Not Designed for Every RMD Scenario: The calculator does not cover all distribution situations, such as inherited retirement accounts subject to beneficiary-specific RMD rules, multiple beneficiaries, certain trust beneficiaries, or other complex IRS exceptions.
-
Assumes Current IRS Rules Remain in Effect: Current-year calculations use the applicable IRS life expectancy tables and distribution rules available today. Future projections do not account for changes to IRS regulations or legislation that may affect future RMD requirements.
-
Projection Assumptions Are Hypothetical: Multi-year projections assume a fixed annual rate of return and scheduled RMD withdrawals. Actual investment performance, account balances, and future distributions will vary over time.
-
Does Not Calculate Taxes or Penalties: The calculator estimates your required minimum distribution only. It does not calculate federal or state income taxes, withholding amounts, potential excise taxes, or the overall tax impact of taking your distribution.
-
Not Financial or Tax Advice: The estimated RMD should be used for educational and planning purposes only. Before making retirement distribution decisions, confirm your required withdrawal amount with your retirement plan administrator or a qualified tax professional.
What to Do With Your RMD Once You Know the Number
Once you know your required minimum distribution (RMD), the next step is to plan how and when you will take the withdrawal while meeting IRS requirements. Taking the correct amount by the applicable deadline can help you stay compliant and avoid unnecessary penalties.
Confirm the Calculated Amount:
Compare the estimated RMD with the amount provided by your retirement plan administrator or IRA custodian to ensure it reflects your account information and the applicable IRS rules.
Coordinate Multiple Retirement Accounts:
If you own multiple eligible retirement accounts, understand the IRS aggregation rules for your account type before taking withdrawals. Some accounts allow RMDs to be aggregated, while others require separate withdrawals.
Withdraw the Required Amount on Time:
Take at least your required minimum distribution by the applicable IRS deadline for the calculation year. Failing to withdraw the full amount may result in an IRS excise tax on the undistributed portion.
Update Your Retirement Income Plan:
Incorporate your annual RMD into your overall retirement income strategy, cash flow planning, and spending needs to help manage your finances throughout retirement.
Plan for Taxes
RMDs from most tax-deferred retirement accounts are generally taxable as ordinary income. Consider the potential tax impact and whether you want to have federal or state taxes withheld from your distribution.
Consult a Qualified Professional if Needed:
If you have inherited retirement accounts, complex beneficiary arrangements, or questions about tax planning, consult a qualified tax professional or financial advisor before taking your distribution.
