Minimum Required Distribution Calculator

Required minimum distributions sound simple — withdraw a set amount from your retirement accounts each year — but the details depend heavily on whose account it is and who is taking the distribution. An account owner, a surviving spouse, and a non-spouse beneficiary all use different IRS tables, different divisors, and sometimes entirely different sets of rules. Using the wrong table means withdrawing the wrong amount and risking penalties.

The Minimum Required Distribution Calculator on this page handles all three situations in one place. Enter your balance and age, then tell it whether you are the account owner, a spouse beneficiary, or a non-spouse beneficiary. It selects the correct IRS table — the Uniform Lifetime Table or the Single Life Table — looks up your divisor, and shows your required distribution, its share of the balance, and the monthly equivalent.

This guide explains when each table applies, how the beneficiary rules changed under recent law, what the 10-year rule means for inherited accounts, and how to avoid the most expensive mistakes. If you have ever been confused about which divisor belongs to your situation, this page will settle it.

Account Owners: The Uniform Lifetime Table

If the retirement account is yours — a traditional IRA, 401(k), 403(b), or similar tax-deferred account you funded yourself — your distributions are calculated with the IRS Uniform Lifetime Table. The table assumes a joint life expectancy with a hypothetical beneficiary ten years younger than you, which stretches the divisor and keeps required withdrawals smaller than a pure single-life calculation would.

How the Owner Calculation Works

Take your account balance on December 31 of last year and divide it by the table divisor for your age. At 73 the divisor is 26.5, at 75 it is 24.6, at 80 it is 20.2, and at 90 it is 12.2. A 75-year-old with $500,000 therefore must withdraw about $20,325. The calculator performs this lookup automatically — just select “Account owner” and enter your figures.

Spouse Beneficiaries Get Special Treatment

A surviving spouse who inherits a retirement account has options nobody else gets. The most powerful is treating the inherited account as their own: rolling it into their existing IRA or retitling it in their name. Once they do, the ordinary owner rules apply — the Uniform Lifetime Table, the standard beginning age, and no distributions until they reach it.

• Treat as own: The spouse rolls the account over and follows normal owner rules. Best when the spouse is younger than the threshold age.
• Remain a beneficiary: The spouse takes distributions based on their own single life expectancy, recalculated each year, with no 10-year deadline.
• Why it matters: A spouse who treats the account as their own can delay distributions for years or decades, while other beneficiaries face the 10-year rule.

In the calculator, a spouse who has rolled the account over should select the owner or spouse option, both of which use the Uniform Lifetime Table. A spouse taking beneficiary distributions uses life-expectancy recalculation, which generally produces smaller annual amounts than the 10-year rule would.

Non-Spouse Beneficiaries and the 10-Year Rule

The SECURE Act of 2019 rewrote the rules for most non-spouse beneficiaries. Instead of stretching distributions over their own lifetime, most now must empty an inherited traditional IRA or 401(k) entirely by the end of the tenth calendar year after the owner’s death. On top of that, if the original owner was already taking required distributions, the beneficiary must also take annual distributions during years one through nine.

The Single Life Table Still Matters

Even under the 10-year rule, the Single Life Table determines the annual distributions required during the ten-year window when the deceased was already past their beginning date. The table gives one divisor per age — for example, 53.3 at 30, 43.6 at 40, 34.2 at 50, 25.2 at 60, and 17.0 at 70. Divide the prior year-end balance by the divisor for the beneficiary’s age to get that year’s required amount, then empty whatever remains by the end of year ten.

Who Is Exempt From the 10-Year Rule

• Surviving spouses — covered above, with the most flexible options.
• Minor children of the deceased — take life-expectancy distributions until reaching majority, then the 10-year clock starts.
• Disabled or chronically ill individuals — may use their own life expectancy.
• Beneficiaries not more than ten years younger than the deceased — such as a sibling close in age, who may use life-expectancy payments.

These “eligible designated beneficiaries” use the Single Life Table with annual recalculation. In the calculator, select “Non-spouse beneficiary” to apply the Single Life Table to your age and balance.

Comparing the Two Tables Side by Side

The Uniform Lifetime Table and the Single Life Table can produce very different divisors at the same age, because they measure different things. The uniform table blends two lives; the single table measures one.

• At age 75: Uniform divisor 24.6 versus single-life divisor 13.4 — the single-life required distribution is nearly twice as large.
• At age 60: The uniform table does not even start until 72, while the single-life divisor at 60 is 25.2.
• At age 40: Single-life divisor 43.6, producing a required withdrawal of about 2.3 percent — relevant for younger beneficiaries of inherited accounts.
• The trend: Both divisors shrink with age, but the single-life table starts lower and falls faster, forcing larger percentage withdrawals.

This comparison shows why selecting the right situation in the calculator is essential. A 75-year-old owner dividing $500,000 by 24.6 owes about $20,325, while a 75-year-old non-spouse beneficiary dividing the same balance by 13.4 owes about $37,313 — and must still empty the account within ten years.

Deadlines and Penalties You Must Not Miss

Every required distribution has a December 31 deadline, and the penalty for falling short is an excise tax of 25 percent of the shortfall — cut to 10 percent if you fix the error promptly. The old 50 percent penalty was reduced by the SECURE 2.0 Act, but 25 percent of a large distribution is still a painful bill.

• Owners: First distribution due by April 1 after reaching the threshold age; every later one by December 31.
• Beneficiaries under the 10-year rule: Annual distributions by December 31 in years one through nine when required, with the full balance gone by December 31 of year ten.
• Missed year-ten deadline: Whatever remains in the account at the end of the tenth year should have been distributed — the entire leftover balance becomes due.
• Correction: If you discover a shortfall, take the missed amount immediately, file for the reduced 10 percent penalty, and document reasonable cause.

Beneficiaries are especially prone to missing these rules because grief and paperwork delays eat into the first year. If you inherit an account, your first call should be to a tax advisor, not the custodian’s general helpline.

Worked Examples for Each Situation

Let us run three scenarios through the calculator to show how the situation changes the result. Each uses a $500,000 prior year-end balance.

1. Owner, age 75: Select “Account owner.” The Uniform Lifetime Table divisor is 24.6, so the required distribution is about $20,325 — roughly 4.07 percent of the balance.
2. Non-spouse beneficiary, age 40: Select “Non-spouse beneficiary.” The Single Life Table divisor is 43.6, so the annual required amount is about $11,468 — and the full balance must still be emptied within ten years.
3. Spouse beneficiary, age 75: Select “Spouse beneficiary.” The Uniform Lifetime Table applies again: about $20,325, with no 10-year deadline hanging over the account.

Same balance, same age in two of the cases — but the beneficiary owes nearly double the owner’s amount and faces a hard ten-year finish line. The table you use is everything.

Tricky Situations: Trusts, Disclaimers, and Split Accounts

Naming a trust as beneficiary adds a layer of complexity that rewards careful drafting. A properly structured see-through trust lets the IRS look through to the underlying human beneficiaries and apply the 10-year rule to them — but the trust document must be delivered to the account custodian by October 31 of the year after the owner’s death. Miss that paperwork deadline and the account can default to the least favorable payout: a five-year emptying rule if the owner died before their required beginning date.

Disclaimers are another precision tool that few families know about. A beneficiary who does not need the money can formally disclaim it within nine months of the death, passing the account to the contingent beneficiary — often a younger heir in a lower tax bracket, or a charity that pays no tax at all. Done correctly, a disclaimer redirects an IRA to wherever it does the most good; done late or informally, it has no legal effect.

When several people inherit a single account, splitting it into separate inherited IRAs by December 31 of the year after death lets each beneficiary follow their own schedule and use their own age. Without a timely split, the oldest beneficiary’s age can dictate the payout pace for everyone, accelerating taxable distributions for younger heirs who would rather wait. Custodians can process the split, but only if someone asks in time.

Tax Planning Inside the 10-Year Window

Beneficiaries under the 10-year rule control the timing of most of the tax bill, because only the annual required amounts during the window are fixed — the rest can come out in any year, including all at once in year ten. Spreading withdrawals evenly across the decade avoids bunching income into a single punishing bracket, which is exactly what happens when heirs procrastinate and then empty the account in the final year at top marginal rates.

Life events inside the window create genuine planning opportunities. A beneficiary who retires, takes a sabbatical, goes back to school, or otherwise has a low-income year can pull larger distributions at much lower rates than during peak earning years. Mapping the ten-year window against your expected income curve — and coordinating with a tax advisor — can save tens of thousands of dollars.

Charitable beneficiaries change the picture entirely. Leaving an IRA to a qualified charity means the 10-year distribution is received tax-free, making retirement accounts the most tax-efficient asset to leave to causes you support. Many estate plans deliberately steer IRAs to charities and leave appreciated stock or real estate — which get a step-up in basis — to human heirs instead.

Frequently Asked Questions

What is the difference between an RMD and a minimum required distribution?

There is no difference — the terms are interchangeable. Both refer to the annual amount the IRS requires you to withdraw from tax-deferred retirement accounts, calculated from your balance and an IRS life expectancy divisor.

Which IRS table should I use for my distribution?

Account owners and spouse beneficiaries use the Uniform Lifetime Table. Non-spouse beneficiaries and certain eligible beneficiaries use the Single Life Table. When a spouse is more than ten years younger and is the sole beneficiary, the Joint and Last Survivor Table applies.

How does the 10-year rule work for inherited IRAs?

Most non-spouse beneficiaries must empty an inherited traditional IRA or 401(k) by December 31 of the tenth year after the owner’s death. If the owner was already taking distributions, annual distributions are also required during the ten-year window.

Can a spouse delay distributions from an inherited IRA?

Yes. A surviving spouse may roll the inherited account into their own IRA and follow normal owner rules, which means no distributions until they reach the threshold age themselves. This is usually the best option for younger spouses.

What divisor does a 75-year-old use?

An account owner or spouse beneficiary age 75 uses the Uniform Lifetime Table divisor of 24.6. A non-spouse beneficiary age 75 uses the Single Life Table divisor of 13.4 — a much larger required withdrawal.

Are Roth IRAs subject to required distributions for beneficiaries?

Beneficiaries of Roth IRAs must still empty the account within ten years in most cases, but the distributions are generally tax-free since the original owner already paid tax on the contributions.

What is the penalty for missing a required distribution?

The excise tax is 25 percent of the amount you failed to withdraw, reduced to 10 percent if corrected promptly. You must still take the missed distribution and pay ordinary income tax on it.

Do you pay tax on a required distribution?

Distributions from traditional IRAs and 401(k)s are taxed as ordinary income. They can also increase your Medicare premiums two years later through income-related surcharges.

Can you take the distribution from a different account?

For IRAs, you may aggregate: calculate each IRA’s share but withdraw the total from any one of them. For 401(k)s and other employer plans, each plan’s distribution must come out of that plan.

What happens if the account owner dies mid-year?

If the owner had not yet taken that year’s required distribution, the beneficiary must take it by December 31 of the year of death, based on the owner’s divisor for that year.

Do minor children follow the 10-year rule?

Not immediately. A minor child of the deceased takes life-expectancy distributions until reaching the age of majority, and the 10-year clock starts at that point.

Can a trust be a beneficiary?

Yes, but the rules are complex. See-through trusts can qualify for beneficiary treatment, while other trusts may force faster distribution. Trust paperwork should always be reviewed by an estate attorney.

How do you calculate the distribution for multiple beneficiaries?

If an account is split into separate inherited IRAs by December 31 of the year after death, each beneficiary uses their own age and the 10-year rule. If not split in time, the oldest beneficiary’s age can govern the payout.

Is it better to take the distribution early or late in the year?

The amount is the same either way, but taking it early removes the risk of missing the December 31 deadline. Some retirees also coordinate timing with Roth conversions and charitable distributions for tax efficiency.

Does this calculator replace professional tax advice?

No. It applies the correct IRS tables to your inputs, but inherited accounts, trusts, disclaimers, and multi-state issues deserve professional review. Use the result as a planning estimate.

The Minimum Required Distribution Calculator takes the guesswork out of which table applies to your situation. Select the option that matches your role, enter your numbers, and you will have the right divisor and the right amount in seconds — then mark December 31 on your calendar and take it on time.
