RMD Calculator
Free Required Minimum Distribution Tool
Use this RMD Calculator to estimate how much you may need to withdraw from your retirement account this year. Under current federal tax rules, eligible retirement account owners are generally required to begin taking minimum distributions once they reach the applicable required beginning age. A missed RMD can generally be subject to a 25% excise tax on the shortfall amount, potentially reduced to 10% if corrected within the applicable two-year correction period by filing Form 5329. This tool gives you an estimate in seconds.
This calculator is designed as a general estimate for individual account owners of traditional IRAs and other applicable tax-deferred accounts. Employer-sponsored plans such as 401(k) and 403(b) plans may have special rules, particularly for account owners who are still employed by the plan sponsor. Consult your plan administrator or a qualified tax advisor for those situations.
Future Account Balance and RMDs
Illustrative projection only. This is not a tax or legal forecast. It assumes the rate of return entered above, no additional contributions, and no other withdrawals beyond the required RMD. Each year’s RMD is subtracted from the prior year-end balance after applying the assumed return. Actual account performance will differ.

What Is an RMD Calculator?
An RMD Calculator is a straightforward tool that tells you the minimum amount you must withdraw from your tax-deferred retirement accounts each year once you reach the applicable age threshold. The acronym RMD stands for Required Minimum Distribution. If you own a traditional IRA, a 401(k), a 403(b), or most other employer-sponsored retirement plans, tax rules generally require eligible account owners to begin taking minimum distributions once they reach the applicable required beginning age, so that the deferred tax on those accounts is eventually recognized.
This RMD Calculator handles the math for you. It takes your account balance from December 31 of the prior year, divides it by a life expectancy factor, and shows you the estimated dollar amount you may need to withdraw. The tool also projects your RMD for future years, so you can plan ahead and avoid the excise tax that can apply to a missed distribution.
How Does This RMD Calculator Work?
The core formula behind every RMD Calculator is simple: RMD = Account Balance ÷ Life Expectancy Factor. The applicable life expectancy factors are published in Publication 590-B. The factor depends on your age and, in some cases, your spouse’s age.
Here is what this RMD Calculator does step by step:
- It calculates your age from the year of birth and the RMD year you enter.
- It looks up the life expectancy factor for your age from the Uniform Lifetime Table (Publication 590-B, Table III), which applies to the distribution year you enter.
- If your spouse is the sole beneficiary and is more than 10 years younger, the RMD Calculator shows a notice directing you to Publication 590-B Table II (the Joint Life and Last Survivor Table), because the exact factor for your age combination must be read from that table.
- It divides the balance by the factor to get your estimated RMD.
- It shows the RMD percentage and your estimated remaining balance after the withdrawal, plus a multi-year projection.
That is the entire process. There is no guesswork and no hidden complexity. The RMD Calculator is designed to be a clean, focused tool — it does not mix in 401(k), SEP IRA, or SIMPLE IRA dropdowns because those account types have their own separate calculators.
First RMD Deadline: April 1 Exception
Your first RMD has a special rule. While subsequent RMDs are generally due by December 31 each year, your first RMD may generally be delayed until April 1 of the year following the year you reach your applicable RMD age. This date is called your Required Beginning Date (RBD).
Be careful, though: if you delay your first RMD to the following April, you must still take your second RMD by December 31 of that same calendar year. That means two taxable distributions in one year, which can push you into a higher tax bracket or increase Medicare premium surcharges. Many retirees choose to take their first RMD in the year they reach RMD age to avoid this doubling effect. The RMD Calculator estimates the amount, but the timing decision is one to make with your tax advisor.
RMD Age Rules: When Do You Have to Start?
The age at which RMDs begin has shifted several times in recent years. Under current federal law, the rules are now staggered based on your birth year. The table below shows the current schedule for individual account owners of traditional IRAs and other applicable tax-deferred accounts.
| Birth Year | Applicable RMD Age | Notes |
|---|---|---|
| 1950 or earlier | 72 | Already reached RMD age (historical age) |
| 1951 – 1959 | 73 | Reach age 73 between 2024 and 2032 |
| 1960 or later | 75 | Individuals who attain age 74 after Dec 31, 2032 |
Age 72 was the applicable RMD age under the older rules and continues to apply only to individuals who were already at that age under the previous schedule. Under the current rules, the applicable age is 73 for those born between 1951 and 1959, and 75 for those born in 1960 or later (this applies to individuals who attain age 74 after December 31, 2032). This RMD Calculator automatically applies the correct factor for whatever age you enter. Employer plans may have special rules — particularly for account owners who are still employed by the plan sponsor — so consult your plan administrator for those situations.
RMD Calculator for Spouses Who Are Sole Beneficiaries and More Than 10 Years Younger
One of the most overlooked situations in RMD planning is the “younger spouse” scenario. If your spouse is the sole beneficiary and is more than 10 years younger than you, the applicable rules allow the use of the Joint Life and Last Survivor Expectancy Table (Publication 590-B, Table II) instead of the Uniform Lifetime Table. This table produces a larger life expectancy factor, which means a smaller RMD — and a smaller tax bill.
Our RMD Calculator asks whether your spouse is the sole beneficiary. When the answer is Yes and the birth years show the spouse is more than 10 years younger, the calculator shows a notice directing you to the current Publication 590-B Table II, because the exact joint life factor for your age combination must be read directly from that table. This approach ensures that no approximated factor is ever used.
If your spouse is not the sole beneficiary, or is not more than 10 years younger, the RMD Calculator uses the Uniform Lifetime Table — the table most retirees use.
Understanding the Life Expectancy Factor
The life expectancy factor is the divisor used to spread your retirement account over your expected lifetime. The Uniform Lifetime Table, updated in 2022, reflects longer life expectancies than the older tables did. That means the factors are slightly larger, which results in slightly smaller RMDs for most people.
For example, at age 75 the factor is 24.6. That translates to an RMD percentage of about 4.07%. At age 80 the factor drops to 20.2, pushing the RMD percentage up to roughly 4.95%. The older you get, the higher the percentage you must withdraw.
A reliable RMD Calculator uses the Uniform Lifetime Table (Publication 590-B, Table III), which applies to the distribution year you enter. This calculator also directs you to the Joint Life and Last Survivor Table when the younger-spouse exception applies, so you can look up the exact factor from the current published table — you can see the factor, the percentage, and the remaining balance right on the results card.
About the Table Values Used in This Calculator
The calculator currently uses the Uniform Lifetime Table as published in IRS Publication 590-B (Table III). The factors reflect the current published edition of that publication. The IRS may revise these tables in a future edition, in which case the calculator values would need to be reviewed and re-entered to match the new tables. Users should verify the applicable factor against the latest IRS publication before relying on the result.
Why You Should Use an RMD Calculator Every Year
RMDs are not a one-time event. You have to take a distribution every single year once you reach your start age. The amount changes each year because your account balance changes and your life expectancy factor changes. Relying on memory or a rough estimate is risky.
A missed RMD can generally be subject to a 25% excise tax on the shortfall amount, and the penalty can potentially be reduced to 10% if the missed distribution is corrected within the applicable two-year correction period by filing Form 5329. A RMD Calculator takes five seconds to use and helps eliminate that risk.
Beyond penalties, knowing your RMD helps with tax planning. The distribution is taxable income. If you know the number in advance, you can adjust your withholding, plan for quarterly estimated taxes, or decide whether to take the RMD early in the year versus late.
RMD Calculator vs. Other Retirement Calculators
Many online calculators try to do everything at once. They mix RMDs with 401(k) projections, SEP IRA rules, and SIMPLE IRA nuances. That approach creates confusion and often produces inaccurate results.
This RMD Calculator is intentionally focused. It calculates one thing: your Required Minimum Distribution. There are no account-type dropdowns, no contribution fields, and no distracting options. You enter your balance and your age, and you get the answer. If you need a 401(k) calculator or a SEP IRA calculator, those are separate tools. This page is dedicated solely to RMDs.

Frequently Asked Questions About the RMD Calculator
Are the life expectancy factors in this calculator kept up to date?
The calculator currently uses the Uniform Lifetime Table as published in IRS Publication 590-B (Table III). The factors reflect the current published edition of that publication. The IRS may revise these tables in a future edition, in which case the calculator values would need to be reviewed and re-entered to match the new tables. Always verify the applicable factor against the latest IRS publication before relying on the result.
Does this calculator apply to 401(k) or 403(b) accounts?
This calculator is designed as a general estimate for individual account owners of traditional IRAs and other applicable tax-deferred accounts. Employer-sponsored plans such as 401(k) and 403(b) plans may have special rules — particularly for account owners who are still employed by the plan sponsor. Consult your plan administrator or a qualified tax advisor for those situations.
What if my spouse is exactly 10 years younger?
The special joint life rule only applies when your spouse is more than 10 years younger. If they are exactly 10 years younger, you use the Uniform Lifetime Table. This RMD Calculator follows that rule precisely.
How does the calculator handle the joint life situation for a younger spouse?
When both conditions are met — your spouse is the sole beneficiary AND is more than 10 years younger than you — the applicable rules allow the use of the Joint Life and Last Survivor Table (Publication 590-B, Table II). The calculator shows a notice directing you to that table so you can look up the exact factor for your age combination. The joint life factor depends on both your age and your spouse’s age, and it must be read directly from the current published table.
What is the deadline for the first RMD?
Your first RMD may generally be delayed until April 1 of the year following the year you reach your applicable RMD age. This date is called your Required Beginning Date. Subsequent RMDs are generally due by December 31 each year. If you delay your first RMD to April 1, you must still take your second RMD by December 31 of that same year, resulting in two taxable distributions in one calendar year. Many retirees choose to take the first RMD in the year they reach RMD age to avoid this doubling effect.
Can I use this RMD Calculator for an inherited IRA?
No. Inherited IRAs follow a different set of rules, including the 10-year rule for most non-spouse beneficiaries. This RMD Calculator is designed for original account owners who are calculating their own lifetime RMDs.
Does the RMD Calculator account for Roth accounts?
Roth IRAs and designated Roth accounts in 401(k) plans are not subject to RMDs during the owner’s lifetime. This RMD Calculator assumes you are working with a tax-deferred account like a traditional IRA or a pre-tax 401(k).
What is the penalty for missing an RMD?
A missed RMD can generally be subject to a 25% excise tax on the shortfall amount. The penalty can potentially be reduced to 10% if the missed distribution is corrected within the applicable two-year correction period, which generally requires taking the missed distribution and filing Form 5329 with your tax return. Using an RMD Calculator each year helps you avoid this tax entirely.
Final Thoughts on Using the RMD Calculator
Once you reach the applicable RMD age, you must withdraw a minimum amount every year. The RMD Calculator on this page gives you that number instantly, without account-type confusion and without unnecessary complexity.
Use it once a year. Enter your year of birth, confirm the RMD year, enter your prior year-end balance, and answer the spouse question if it applies. The RMD Calculator does the rest. It shows your estimated RMD, the life expectancy factor, the RMD percentage, and your remaining balance after the withdrawal. It even projects future years so you can see how the numbers evolve.
Bookmark this RMD Calculator and come back every January when you are planning your withdrawals for the year. A few seconds of input can help you avoid the 25% excise tax and keep your tax situation under control.
