RMD Calculator: Required Minimum Distribution (2025) Updated Feb 2026

Who this is for: IRA and 401(k) owners age 73+ who must take required minimum distributions to avoid IRS penalties.

A Required Minimum Distribution (RMD) is the minimum amount you must withdraw annually from your tax-deferred retirement accounts once you reach a certain age. The IRS mandates these withdrawals to ensure that retirement savings are actually used during retirement, rather than passed on as tax-deferred inheritances.

What Is a Required Minimum Distribution (RMD)?

RMDs are minimum amounts that retirement plan account owners must withdraw annually starting at age 73 (or 72 if you turned 72 before 2023). The amount is calculated by dividing the prior year-end account balance by a life expectancy factor determined by the IRS.

Purpose of RMDs

• Ensure tax-deferred savings are used during retirement
• Prevent using retirement accounts as estate planning tools
• Generate tax revenue from previously tax-deferred growth

Which Accounts Are Subject to RMDs?

Required Minimum Distributions apply to nearly all tax-deferred retirement accounts, including traditional IRAs, SEP IRAs, SIMPLE IRAs, and most employer-sponsored plans such as 401(k), 403(b), and 457(b). Roth IRAs are the primary exception — they are not subject to RMDs during the original owner's lifetime, making them a powerful estate planning and tax-deferral tool for higher earners.

Accounts That DO Have RMDs

• Traditional IRAs
• SEP IRAs
• SIMPLE IRAs
• 401(k), 403(b), 457 plans
• Profit-sharing plans
• Other defined contribution plans

Accounts That Do NOT Have RMDs

• Roth IRAs (during owner's lifetime)
• Roth 401(k) (during owner's lifetime, but must roll to Roth IRA before death to avoid RMDs)

When Must You Take RMDs?

Under the SECURE 2.0 Act, most retirement account owners must begin taking RMDs by April 1 of the year following the year they turn 73. Every year after that, the RMD deadline is December 31. If you delay your first RMD until April 1, you will owe two RMDs in that calendar year — which may push you into a higher tax bracket and increase your Medicare premiums.

RMD Start Age

• Turning 73 in 2023 or later: First RMD by April 1 of the year after you turn 73
• Turned 72 in 2022 or earlier: Follow previous rules (already taking RMDs)

Deadline Rules

• First RMD: April 1 of the year after you turn 73
• Subsequent RMDs: December 31 each year
• Two RMDs in one year: If you delay first RMD to April 1, you must also take second RMD by December 31

How to Calculate Your RMD

Your annual RMD is calculated by dividing your prior December 31 account balance by a distribution period factor from the IRS Uniform Lifetime Table. The distribution period is based on your age at year-end and decreases each year, meaning your RMD percentage gradually increases as you age. For most account owners with a non-spouse beneficiary more than 10 years younger, the Joint Life Expectancy Table is used instead, which produces lower RMDs.

Uniform Lifetime Table (Partial)

The IRS Uniform Lifetime Table lists the Distribution Period factor for each age, which is used to calculate your annual RMD. The table below covers ages 73–80 — the most commonly used range. The full table extends to age 120 and is published in IRS Publication 590-B, Appendix B. As your age increases each year, the distribution period decreases, resulting in progressively larger RMD requirements.

RMD Penalties

Failing to take the full required minimum distribution each year triggers one of the most serious IRS retirement account penalties. Beginning in 2023 (under SECURE 2.0), the excise tax rate was reduced from 50% to 25% of the shortfall, and further reduced to 10% if you correct the mistake within a two-year window. The penalty is applied only to the amount you failed to withdraw, not your total account balance, and can be waived if the failure was due to reasonable cause.

• Penalty rate: 25% excise tax on amount not withdrawn (down from 50% in 2023)
• Reduced penalty: If corrected within 2 years, penalty drops to 10%
• Waiver possible: Can request waiver by filing Form 5329 if failure was due to reasonable error

RMD Strategies

While RMDs are mandatory, how you handle them is not. Savvy retirement planning focuses on minimizing the tax impact of RMDs through strategies like Qualified Charitable Distributions, Roth conversions before age 73, strategic timing of the first RMD, and coordinating withdrawals across multiple accounts. The right combination can reduce your adjusted gross income, lower Medicare premiums, and increase after-tax wealth for you and your heirs.

1. Qualified Charitable Distributions (QCDs)

If you are 70.5 or older, you can donate up to $100,000 directly to charity from your IRA. This counts toward your RMD but is not included in taxable income.

2. Roth Conversions

Convert traditional IRA funds to Roth IRA before RMD age. Roth IRAs do not have RMDs during your lifetime, though conversions are taxable events.

3. Delay First RMD Strategically

Consider whether taking your first RMD in the year you turn 73 vs. waiting until April 1 of the next year makes sense for your tax situation.

4. Coordinate Multiple Accounts

Calculate RMDs separately for each IRA, but you can take the total from one account. 401(k) RMDs must be taken from each plan separately.

Qualified Charitable Distributions (QCDs)

A Qualified Charitable Distribution allows IRA owners age 70½ or older to donate up to $100,000 annually (indexed for inflation starting 2024) directly from their IRA to a qualifying charity. The transferred amount is excluded from taxable income entirely — it does not count as a deduction, but it never enters your adjusted gross income (AGI), which can reduce Medicare premiums, phase-in thresholds for Social Security taxation, and other income-based benefits.

• Maximum: $100,000 per year
• Tax benefit: Excluded from taxable income entirely
• Count toward RMD: Yes
• Direct payment required: Must go directly to charity from IRA

Spousal Rules

Surviving spouses have the most favorable RMD treatment of any beneficiary category. A spouse who inherits a retirement account can roll it into their own IRA, treating it as if they were always the owner — which means they use their own age to calculate RMDs, can name new beneficiaries, and are not subject to the 10-year distribution rule that applies to most other inheritors. Spouses who are more than 10 years younger than the account owner also benefit from using the IRS Joint Life Expectancy Table, which produces significantly lower annual RMDs.

• Spousal beneficiaries: Can roll inherited IRA into their own IRA
• Younger spouse: If sole beneficiary and more than 10 years younger, use Joint Life Expectancy table (lower RMDs)
• RMD timing: Surviving spouse can delay RMDs until deceased spouse would have turned 73

Inherited IRA RMDs

The SECURE Act of 2019 fundamentally changed how most beneficiaries must take distributions from inherited retirement accounts. Before 2020, non-spouse beneficiaries could stretch distributions over their own lifetime (the "Stretch IRA"). Since 2020, most non-spouse beneficiaries must fully distribute the inherited account within 10 years of the original owner's death, with no requirement for annual withdrawals — though some beneficiary categories remain exempt from this rule.

• 10-Year Rule: Most non-spouse beneficiaries must empty inherited IRA within 10 years
• Exceptions: Spouses, minor children, disabled individuals, and those within 10 years of decedent's age may have different rules
• No annual RMDs required: For most beneficiaries, but all must be distributed by year 10

Roth 401(k) RMDs

While traditional Roth IRAs have no RMDs during the original owner's lifetime, Roth 401(k) accounts — which are employer-sponsored — were subject to RMDs until a significant change took effect in 2024. The SECURE 2.0 Act eliminated RMDs from Roth designated accounts in employer plans starting January 1, 2024, aligning them with Roth IRA rules. Owners of Roth 401(k)s should review their plan documents to confirm whether this change applies and consider rolling older balances to a Roth IRA for full flexibility.

• RMDs required: Yes, starting at 73 (unlike Roth IRAs)
• Solution: Roll to Roth IRA before 73 to avoid RMDs
• Tax treatment: Roth 401(k) RMDs are tax-free (qualified distributions)

RMD Strategy Comparison

Choosing how to handle your RMDs depends on your charitable inclinations, remaining life expectancy, estate goals, and tax situation. The table below compares the four most widely used RMD strategies across the dimensions that matter most for retirement planning.

Real-World RMD Scenarios

Understanding how RMDs work in practice requires seeing them applied to realistic situations. The three scenarios below illustrate how account size, age, charitable giving, and account type each affect the RMD calculation and tax outcome \u2014 and how strategic decisions can make a meaningful difference over a 10- to 15-year retirement horizon.

International RMD Equivalents: How Other Countries Handle Forced Withdrawals

The United States is not unique in requiring savers to draw down tax-deferred retirement accounts. Most developed economies have similar mandatory distribution mechanisms, though they differ substantially in timing, flexibility, and the consequences of non-compliance. Understanding international equivalents is particularly relevant for dual citizens, retirees abroad, or those approaching eligibility under multiple systems.

Your Decade-by-Decade RMD Planning Guide

The most expensive RMD mistakes happen decades before the first mandatory withdrawal. Proactive planning in your 50s and 60s can dramatically reduce the tax burden of RMDs in your 70s and beyond. Here is a practical guide to what you should focus on during each decade.

In Your 50s: Build the Foundation

• Maximize contributions to 401(k) and IRA accounts; take advantage of catch-up contributions ($7,500 extra for 401k; $1,000 extra for IRA from age 50)
• Assess your projected RMD at 73 using current balance \u00d7 expected growth rate \u00f7 26.5 distribution factor
• Consider whether future large RMDs will push you into a higher bracket or trigger Medicare IRMAA surcharges
• Begin small Roth IRA contributions to build tax-free balance outside RMD rules

In Your 60s: Conversion Opportunity Window

• Years between retirement (or early 60s) and age 73 are the optimal window for Roth conversions at potentially lower tax rates
• Convert enough traditional IRA balance each year to "fill" your current tax bracket without triggering the next bracket
• Coordinate with Social Security claiming strategy \u2014 converting before claiming SS maximizes the conversion window
• Review beneficiary designations; consider whether younger spouse or trust as beneficiary changes your optimal RMD table

In Your 70s: Active RMD Management

• Calculate your RMD each year using prior December 31 balance; your custodian is required to provide the calculation but not required to take correct action automatically
• Evaluate QCDs if you are charitably inclined; amounts up to $105,000 can be donated directly (2024 limit)
• Consider timing: January withdrawals maximize reinvestment time; December withdrawals maximize deferral
• If taking two RMDs in first year (delayed first RMD), model the combined income impact before deciding
• Review the Medicare IRMAA income thresholds \u2014 reducing AGI by even $1 can sometimes save $1,700+ annually in Part B/D premiums

In Your 80s and Beyond: Simplification and Legacy

• RMD percentages increase significantly (from ~3.77% at 73 to ~9.26% at 90); plan for growing taxable income
• Consider rolling remaining IRA balance into an immediate annuity to satisfy RMDs automatically and provide predictable income
• Update beneficiary designations to account for SECURE Act 2.0 changes to inherited account rules
• Consult an estate attorney about charitable remainder trusts or other vehicles that can satisfy RMDs while achieving estate goals
