RMD Calculator - IRS Table Withdrawal Estimate

An rmd calculator estimates the minimum amount you may need to withdraw from an eligible tax-deferred retirement account for a distribution year. It is useful when you are turning 73, checking a traditional IRA withdrawal, comparing an IRA with an employer plan, or planning how an RMD may affect cash flow and taxable income. Enter the prior December 31 balance, not today's account quote.

• • Check a traditional IRA withdrawal: Use the prior-year-end balance and your age to estimate the annual distribution required from a traditional IRA, SEP IRA, or SIMPLE IRA.
• • Plan employer-plan cash flow: Estimate a 401(k) or 403(b) distribution, then confirm the result with the plan administrator because employer-plan aggregation and still-working rules can differ.
• • Estimate the tax effect: Enter an illustrative marginal tax rate to see a separate tax estimate and after-tax amount. The result does not replace a full return calculation.
• • Compare beneficiary situations: Test the younger-spouse selection when the spouse is the sole beneficiary and more than 10 years younger, then compare the resulting factor with the standard table.

Required minimum distributions are withdrawals required by federal tax rules from many retirement accounts. The amount is driven mainly by the previous year-end balance and a life-expectancy divisor. This page focuses on an original owner using the 2025 IRS tables; Roth IRA owners and inherited accounts use different rules.

For a broader spending-horizon question beyond the statutory minimum, the Retirement Withdrawal Calculator models how a chosen withdrawal schedule affects retirement savings.

The standard RMD calculation is a division problem: use the prior December 31 account balance and divide it by the IRS distribution period for your age. The calculator then shows an annual amount, a monthly equivalent, a percentage, and an illustrative tax effect.

• Prior December 31 balance: The account value on the last day of the preceding year.
• Distribution factor: The Uniform Lifetime Table divisor, or the Joint and Last Survivor divisor when the spousal exception applies.
• Marginal tax rate: An entered assumption used only to illustrate tax impact as RMD × rate.

The IRS Publication 590-B (2025) example uses a 73-year-old with a $38,400 prior-year balance and divides by 26.5, producing about $1,450. That example supports the same order of operations used here. The age-75 factor is 24.6, so the percentage of the balance rises gradually as the divisor falls with age.

The younger-spouse option is anchored to the IRS publication's age-75 and spouse-age-64 example, where the divisor is 25.3. Verify the exact age-pair divisor in the current IRS worksheet before acting.

According to Internal Revenue Service, Publication 590-B (2025), an IRA owner's distribution generally uses the prior December 31 balance divided by the applicable distribution period, including 26.5 at age 73 and 24.6 at age 75

If you need to project the savings that may fund future distributions, the Retirement Savings Calculator shows contributions and growth before the RMD stage.

Four ideas explain most differences between a calculator result and the number on a custodian statement: the balance date, the table, the tax assumption, and the account rules.

A qualified charitable distribution can change the tax picture because a direct IRA-to-charity transfer may count toward the RMD. The calculator does not subtract a QCD or model eligibility. Traditional IRAs may be aggregated, while employer plans require calculations.

According to Internal Revenue Service, RMD FAQs, many owners begin RMDs at age 73, the first distribution can generally be delayed until April 1 of the following year, and an uncorrected shortfall can face a 25% excise tax

When retirement cash flow includes federal benefits as well as an account withdrawal, the Social Security Calculator can model the Social Security portion separately.

Use this rmd calculator with the account statement and your beneficiary designation rather than guessing from today's market value. Then run a second case with a different tax rate or table choice when you are checking a planning range.

1. 1 Read the account statement: Enter the account value shown for December 31 of the preceding year. Use one eligible account at a time unless your calculation method explicitly allows aggregation.
2. 2 Enter the owner's age: Enter the age reached in the distribution calendar year. This page supports ages 73 through 120 and uses the age-specific IRS factor.
3. 3 Choose the account context: Select traditional IRA, 401(k), 403(b), SEP IRA, or SIMPLE IRA. The selection labels the situation; it does not override plan-specific rules.
4. 4 Check the beneficiary condition: Select yes only if the spouse is the sole beneficiary for the year, then enter the spouse's age. The Joint and Last Survivor exception requires more than a 10-year age difference.
5. 5 Add a tax assumption: Enter a marginal rate if you want the tax and after-tax illustrations. Use zero to see the gross RMD without an estimated tax deduction.
6. 6 Review and verify: Compare annual RMD, factor, table, tax illustration, and remaining balance with your custodian's calculation before arranging a withdrawal.

Suppose your statement shows $500,000 at the prior year-end and you are 75. Start with the standard table and a 22% illustration. Then test the spouse option only if your spouse is the sole beneficiary and more than 10 years younger. Use the lower-return or higher-tax scenario for budgeting, and take the final distribution instruction from your plan administrator.

To place this year's required withdrawal inside a complete retirement timeline, the Retirement Calculator combines savings, income, spending, and retirement-age assumptions.

A table-backed estimate makes the statutory withdrawal easier to discuss with a custodian, tax professional, or household budget. It also keeps the formula inputs visible instead of hiding them in a single percentage.

• • Uses the prior-year balance: The required account date is prominent, reducing the common mistake of substituting today's balance for the prior December 31 value.
• • Shows the actual divisor: Seeing the distribution factor makes it easier to audit the annual amount against the IRS table and understand why the amount changes with age.
• • Separates gross and tax illustrations: Annual RMD, estimated tax, and after-tax RMD are displayed separately so a tax assumption is not mistaken for the statutory withdrawal.
• • Supports household cash flow: The monthly equivalent helps compare a required annual withdrawal with pension, Social Security, and recurring spending needs.
• • Highlights beneficiary context: The spouse fields prompt you to check the sole-beneficiary and more-than-10-years-younger conditions before using the joint-life context.

Compare two labeled cases, such as the standard table, a qualifying younger-spouse case, and a different tax assumption. A withdrawal can affect estimated tax payments, withholding, Medicare premium calculations, and charitable plans, which are outside this calculator.

If a pension will cover part of the household budget, the Pension Calculator estimates that defined-benefit income alongside the RMD cash-flow number.

The formula is short, but several account and tax facts can change whether this estimate matches the amount you should actually distribute.

• • This calculator estimates an original owner's lifetime RMD from eligible account types; it does not calculate inherited-account distributions, Roth IRA lifetime-owner RMDs, annuities, or every plan-specific exception.
• • The younger-spouse result is a planning estimate anchored to the IRS publication example. Confirm the exact age-pair factor in the current IRS worksheet or with the plan administrator before acting.
• • The tax result is not a tax return calculation and does not include state tax, other income, deductions, withholding, Medicare effects, or qualified charitable distributions.
• • The calculator does not decide whether a distribution is timely. Confirm the first-year deadline, later-year deadline, and any correction or relief rules with the IRS guidance and your adviser.

The IRS says an uncorrected RMD shortfall can be subject to a 25% excise tax, with a possible reduction to 10% when corrected within the permitted period. That penalty is not included in the result because it applies to a shortfall and depends on facts beyond the account balance and age.

A qualified charitable distribution is another separate planning choice. IRS Publication 526 describes a direct IRA distribution to a qualified organization and states the 2025 annual exclusion limit is $108,000 for eligible donors. Do not subtract that limit automatically.

According to Internal Revenue Service, Publication 526 (2025), a qualified charitable distribution is made directly from an IRA to a qualified organization, requires age 70 1/2, and has a $108,000 annual exclusion limit for 2025

For a separate comparison with contract-based lifetime income, the Annuity Payout Calculator estimates annuity payout choices rather than an IRS-required withdrawal.
