How to Calculate Your Required Minimum Distribution (RMD) in 2026

Our free RMD calculator (Required Minimum Distribution calculator) helps retirees, financial planners, and beneficiaries determine the exact mandatory withdrawal required by the Internal Revenue Service (IRS). Whether you are managing a Traditional IRA, SEP-IRA, SIMPLE IRA, or employer-sponsored 401(k), calculating your distribution accurately protects you from severe IRS tax penalties while keeping your retirement income plan on track.

The Official IRS RMD Formula Explained

Calculating your minimum distribution is straightforward when using the official IRS formula. The IRS requires you to use the fair market value of your account at the close of business on December 31 of the previous year and divide it by your life expectancy divisor from IRS Uniform Lifetime Table III.

Annual RMD = Prior Year-End Account Balance (Dec 31) ÷ IRS Life Expectancy Factor

1. Dec 31 Balance

Look at your year-end statement (e.g., Dec 31, 2025 balance for your 2026 RMD).

2. Age Factor Divisor

Find your age as of Dec 31 of the distribution year in the IRS table below.

3. Divide & Withdraw

Divide the balance by the factor. Withdraw the full amount before Dec 31.

When Do RMDs Start? SECURE Act 2.0 Age Rules

The Setting Every Community Up for Retirement Enhancement (SECURE) Act 2.0 established a phased increase in the required beginning date for mandatory distributions:

Prior Law

Age 70½ / 72

Applies to individuals born on or before December 31, 1950.

Current Rule

Age 73

Applies to individuals born between 1951 and 1959 (Turning 73 between 2024 and 2032).

Future Rule

Age 75

Applies to individuals born on January 1, 1960, or later (Taking effect in 2033+).

IRA Distribution Rules vs. 401(k) Minimum Distribution Rules

Understanding account aggregation is essential when utilizing an ira minimum distribution calculator versus a workplace retirement calculator:

Traditional, SEP & SIMPLE IRAs (Aggregation Allowed)

If you hold multiple Traditional IRAs at Vanguard, Fidelity, Schwab, or other institutions, you calculate the RMD for each account separately, add the figures together, and withdraw the total from any single IRA or combination of IRAs.

401(k) & 403(b) Plans (No Cross-Plan Aggregation)

Workplace 401(k) plans cannot be aggregated across different plan sponsors. You must satisfy the RMD for each specific 401(k) plan directly from that plan. However, if you are still working past 73 and do not own >5% of the company, you can defer RMDs from your current employer's plan until actual retirement.

Tax Strategy: Lower Your RMD Tax Hit with a Qualified Charitable Distribution (QCD)

Because RMD withdrawals are taxed at ordinary federal and state income tax rates, large distributions can push retirees into higher tax brackets and trigger elevated Medicare IRMAA surcharges. If you do not require the distribution for living expenses, you can direct up to $111,000 in 2026 (indexed for inflation per IRS Notice 2025-67) directly to a qualified 501(c)(3) charity via a Qualified Charitable Distribution (QCD) starting at age 70½. For married couples with separate IRAs, both spouses can donate $111,000 for up to $222,000 combined. Furthermore, under SECURE 2.0 §307, up to $55,000 can be utilized for a one-time split-interest gift annuity or charitable remainder trust.

Calculate your Qualified Charitable Distribution savings

Tax Source Verification: Calculated in accordance with IRS Publication 590-B, Internal Revenue Code (IRC) Section 401(a)(9), Notice 2025-67 (2026 QCD limits), and Treasury Regulation § 1.401(a)(9)-9 (Uniform Lifetime Table III).

Frequently Asked Questions

Authoritative answers to common questions about this calculation

Q1.What is a Required Minimum Distribution (RMD)?

A Required Minimum Distribution (RMD) is the mandatory annual dollar amount that the Internal Revenue Service (IRS) requires retirement savers to withdraw from qualified tax-deferred retirement accounts once reaching a designated age threshold. These accounts include Traditional IRAs, SEP IRAs, SIMPLE IRAs, 401(k)s, 403(b)s, and 457(b) plans. Because contributions to these accounts were made pre-tax and investment returns accumulated tax-deferred over decades, Congress enacted RMD statutes under Internal Revenue Code Section 401(a)(9) to prevent individuals from permanently sheltering accumulated wealth from federal and state income taxes. Distributions are treated as ordinary taxable income rather than preferential capital gains.

Q2.How do you calculate your Required Minimum Distribution (RMD formula)?

Your annual RMD is calculated using a straightforward formula mandated by IRS Publication 590-B: Annual RMD = (Prior Year-End Account Balance as of December 31) ÷ (IRS Life Expectancy Factor). For example, if your Traditional IRA was worth $500,000 on December 31, 2025, and you turn 73 during 2026, your IRS distribution factor from Uniform Lifetime Table III is 26.5. Dividing $500,000 by 26.5 yields a mandatory 2026 distribution of $18,867.92 (or 3.77% of the portfolio). If your spouse is your sole primary beneficiary and is more than 10 years younger than you, you use the IRS Joint Life and Last Survivor Expectancy Table II instead, which provides a larger divisor factor and reduces your required annual withdrawal.

Q3.What is the RMD starting age under SECURE Act 2.0 in 2026?

Under the Setting Every Community Up for Retirement Enhancement (SECURE) Act 2.0 enacted into federal law, the mandatory RMD starting age is determined by your exact year of birth. If you were born between 1951 and 1959, your required beginning age is 73 (taking effect between calendar years 2024 and 2032). If you were born on January 1, 1960, or later, your RMD starting age increases to 75 (taking effect beginning in 2033). Retirees born in 1950 or earlier were grandfathered under prior rules, starting RMDs at age 72 under the original SECURE Act of 2019, or age 70½ under pre-2020 tax law.

Q4.What is my RMD if I turn 73 this year — do I have to take it by December 31?

If you turn age 73 during the current calendar year, IRS regulations provide a one-time grace period granting you until April 1 of the following year (known as your Required Beginning Date or RBD) to take your initial RMD. However, deciding to delay your first RMD until April 1 creates a severe tax trap: you will be forced to take two RMDs in that single subsequent tax year. Specifically, you must take your deferred first-year RMD on or before April 1, and your second-year RMD on or before December 31. Doubling up distributions in a single 12-month period bunches taxable income, which frequently pushes retirees into higher marginal tax brackets, triggers elevated Medicare Part B and Part D IRMAA surcharges, and renders up to 85% of Social Security benefits taxable. Most CPAs recommend taking the first RMD by December 31 of your 73rd birthday year unless your income that year is exceptionally high due to pre-retirement wages.

Q5.How does an IRA distribution calculator differ for multiple Traditional IRAs vs 401(k)s?

The IRS enforces distinct aggregation rules depending on whether funds are held in individual retirement arrangements or employer-sponsored plans. If you own multiple Traditional IRAs, SEP IRAs, or SIMPLE IRAs across different brokerage custodians (e.g., Vanguard, Fidelity, Schwab), you calculate the RMD separately for each account, add the totals together, and withdraw the aggregate amount from any single IRA or combination of IRAs you choose. In contrast, workplace 401(k), 403(b), and 457(b) plans cannot be aggregated across different employers; you must compute and distribute the exact RMD from each respective plan individually. Furthermore, if you are actively employed past age 73 and do not own 5% or more of the employer, you can defer RMDs from your current employer's 401(k) under the "still-working" exception until actual retirement.

Q6.What is the penalty for missing an RMD or withdrawing too little?

Prior to SECURE Act 2.0, the IRS imposed one of the harshest penalties in the tax code: a 50% excise tax on any undistributed RMD shortfall. Under SECURE 2.0 (IRC Section 4974), Congress reduced the standard excise penalty to 25% of the shortfall amount. Furthermore, if the taxpayer identifies the error and withdraws the corrective distribution within a statutory two-year "correction window" while filing IRS Form 5329 with their return, the penalty is further reduced to just 10%. If the shortfall was due to reasonable cause (such as serious illness, mental incapacity, or custodian calculation error), taxpayers can submit Form 5329 with a formal Letter of Explanation requesting a complete waiver of the excise tax penalty under IRS reasonable cause provisions.

Q7.Do Roth IRAs have required minimum distributions?

No. Original Roth IRA owners are completely exempt from Required Minimum Distributions throughout their entire lifetime. Because contributions were funded with after-tax dollars and qualified earnings are permanently tax-free, the IRS does not require mandatory distributions while the owner is alive. Additionally, beginning on January 1, 2024, SECURE Act 2.0 eliminated pre-death RMDs for employer-sponsored designated Roth 401(k) and Roth 403(b) accounts, placing them on equal footing with Roth IRAs. However, non-spouse beneficiaries who inherit either a Traditional or Roth IRA remain subject to post-death distribution rules, typically requiring complete account liquidation within 10 calendar years under the SECURE Act 10-year rule.

Q8.Can I satisfy my RMD using a Qualified Charitable Distribution (QCD)?

Yes. If you are age 70½ or older, you can execute a Qualified Charitable Distribution (QCD) of up to $111,000 in 2026 (indexed for inflation per IRS Notice 2025-67, up from $108,000 in 2025 and $105,000 in 2024) directly from your Traditional IRA to a qualified 501(c)(3) public charity. For married couples filing jointly where each spouse maintains their own IRA, each spouse can donate up to $111,000, allowing a total family distribution of up to $222,000. Under SECURE 2.0 Section 307, taxpayers can also utilize up to $55,000 of their QCD limit as a one-time election to fund a split-interest entity, such as a Charitable Remainder Unitrust (CRUT), Charitable Remainder Annuity Trust (CRAT), or Charitable Gift Annuity (CGA). QCD amounts count dollar-for-dollar toward satisfying your annual RMD but are 100% excluded from your adjusted gross income (AGI).

Q9.Can I roll over or convert my RMD directly to a Roth IRA?

No. Internal Revenue Code regulations explicitly prohibit rolling over or converting any mandatory RMD dollars into a Roth IRA. The IRS operates under a strict "first dollars out" rule: every dollar withdrawn from a tax-deferred account during an RMD year is legally deemed to satisfy the RMD first until your total annual RMD requirement has been completely fulfilled. Attempting to convert RMD funds to a Roth IRA creates an ineligible rollover, triggering excess contribution penalties of 6% per year on Form 5329 until corrected. However, once you have fully satisfied your RMD requirement for the tax year and paid ordinary income taxes on that withdrawal, any additional voluntary distributions above the RMD threshold can be converted to a Roth IRA without restriction.
