What Are Required Minimum Distributions and Why Do They Matter for Your Retirement?
The IRS requires you to withdraw a minimum amount from your traditional IRA, 401(k), and most other retirement accounts each year once you reach age 73. This is called a Required Minimum Distribution (RMD). The rule exists because these accounts received tax-deferred contributions, and the IRS wants to eventually collect income tax on the money. Failing to take your RMD results in a significant tax penalty.
Under the SECURE 2.0 Act signed in December 2022, the RMD starting age increased to 73 for individuals who turn 72 after December 31, 2022. The age will further increase to 75 in 2033 for those born in 1960 or later. Total US IRA assets reached $19.2 trillion as of December 31, 2025, according to the Investment Company Institute. This calculator uses the IRS Uniform Lifetime Table to determine your RMD and projects your distribution schedule for the next 10 years. For tracking your retirement savings growth, pair this with our 401(k) Calculator.
Inputs Required
- Your Current Age: Must be 73 or older to have RMD obligations
- Prior Year-End Account Balance: The December 31 balance of the account from the previous year
- Expected Annual Return: Used to project the future balance for the multi-year schedule
Outputs Provided
- This Year's RMD: The exact amount you must withdraw this year
- Monthly Equivalent: The RMD divided by 12 for budgeting purposes
- RMD as a Percentage: What fraction of your balance must be withdrawn
- 10-Year Schedule: Age-by-age projection of balance, RMD, and distribution period
How the Calculation Works
The IRS RMD formula divides your prior December 31 account balance by a life expectancy factor from the Uniform Lifetime Table. This factor decreases each year as you age, requiring you to withdraw a larger percentage of your balance over time. The IRS updated the Uniform Lifetime Table in 2022, extending life expectancy factors to reflect longer average lifespans.
RMD = Prior Year-End Balance / IRS Distribution Period
For example, at age 73 the distribution period is 26.5 years. At age 80 it drops to 20.2 years. At age 85 it is 16.3 years. This means a larger share of the account must be distributed as you get older. The multi-year schedule uses the projected balance each year (after withdrawing the RMD and applying investment growth) to recalculate the next year's distribution.

How to Use the Calculator
- Enter your current age (must be 73 or older for RMD obligations)
- Look up your account statement for the December 31 balance from last year
- Enter that balance as the prior year-end balance
- Set an expected return rate for the projection
- Review your current year RMD and the 10-year schedule
Example Calculations
Example 1: First-Year RMD at Age 73
Robert, a 73-year-old retiree in Arizona, has a traditional IRA with a December 31, 2025 balance of $500,000. His first RMD is due for 2026:
- IRS distribution period at age 73: 26.5 years
- RMD: $500,000 / 26.5 = $18,868
- Monthly equivalent: $1,572
- RMD as percentage of balance: 3.77%
Robert must withdraw at least $18,868 during 2026. Since this is his first RMD, he could delay it until April 1, 2027, but then he would need to take two RMDs in 2027 (his 2026 RMD plus his 2027 RMD), which could push him into a higher tax bracket.
Example 2: RMD at Age 80 With Growth
Patricia, an 80-year-old widow in Florida, has an IRA balance of $520,000 as of December 31, 2025. Her account has grown despite taking RMDs for 7 years:
- IRS distribution period at age 80: 20.2 years
- RMD: $520,000 / 20.2 = $25,743
- Monthly equivalent: $2,145
- RMD as percentage of balance: 4.95%
By age 80, the required withdrawal percentage has increased from 3.77% to 4.95%. If Patricia's account earns 6% per year, the growth still outpaces the RMD, but the gap narrows each year. By age 85, the distribution period drops to 16.3 years, requiring 6.13% of the balance to be withdrawn.
Real-World Scenarios
Tax Bracket Management
Margaret, a 75-year-old retiree in Pennsylvania, has $400,000 in her traditional IRA and $50,000 in Social Security income. Her 2026 RMD is $400,000 / 24.6 = $16,260. This pushes her total taxable income to approximately $66,260, keeping her in the 22% federal tax bracket. By knowing her RMD in advance, she makes quarterly estimated tax payments of $3,600 each to avoid underpayment penalties. Without planning, she would face an unexpected $3,500 tax bill plus penalties in April. For assessing your overall financial position, use our Net Worth Calculator.
Qualified Charitable Distributions
James, a 78-year-old in Texas, donates $15,000 annually to his church. Instead of taking his full RMD as taxable income and then donating, he uses a Qualified Charitable Distribution (QCD) to send $15,000 directly from his IRA to the church. The QCD counts toward his RMD requirement but is excluded from his taxable income. For 2025 and 2026, the QCD limit is $108,000 per year per individual. This strategy saves him approximately $3,300 in federal income taxes annually compared to taking the RMD as income and then donating.
Multiple Account Management
Linda, a 76-year-old in California, has three traditional IRAs at different brokerages with balances of $200,000, $150,000, and $100,000. She must calculate the RMD for each account separately but can withdraw the total from any one or combination of accounts. Her total RMD for 2026 is approximately $18,700. She chooses to withdraw it all from the largest account to simplify management. For 401(k) plans, the RMD from each plan must be taken from that specific plan. Linda uses this calculator for each account separately and adds the results.
Why This Calculation Matters
Missing an RMD triggers a 25% excise tax on the amount that should have been withdrawn (reduced to 10% if corrected within two years under SECURE 2.0). For a $20,000 RMD, that penalty is up to $5,000 on top of the income taxes owed. Knowing your exact RMD each year is essential for both compliance and tax planning. With $19.2 trillion in US IRA assets as of December 2025, RMDs affect millions of retirees annually. The IRS updated the Uniform Lifetime Table in 2022 to reflect longer life expectancies, slightly reducing required distribution amounts compared to the old table.
Common Mistakes to Avoid
- Using the wrong balance date: Always use the December 31 balance from the prior year, not the current balance. If your December 31, 2025 balance was $500,000 but the account grew to $540,000 by March 2026, you still use $500,000 for the 2026 RMD calculation
- Forgetting the first year deadline: Your first RMD can be delayed until April 1 of the year after you turn 73, but taking two distributions in one year increases your taxable income significantly. If you turn 73 in 2026 and delay to April 1, 2027, you must take both your 2026 and 2027 RMDs in 2027
- Ignoring inherited accounts: Inherited IRAs have different RMD rules from your own accounts. The SECURE Act requires most non-spouse beneficiaries to deplete the account within 10 years. Spousal beneficiaries have different options. Consult a tax professional for inherited account rules
- Applying 401(k) RMD rules to IRAs: Still working after 73? You may delay RMDs from your current employer's 401(k) if you are still employed there, but not from traditional IRAs or old 401(k)s from previous employers
- Not considering Roth conversions before RMD age: Converting traditional IRA funds to a Roth IRA before age 73 reduces future RMDs since Roth IRAs have no lifetime RMD requirement. This strategy requires paying taxes on the converted amount but can save significantly over the long term
Limitations of This Calculator
This calculator uses the IRS Uniform Lifetime Table for account owners. If your spouse is the sole beneficiary and is more than 10 years younger than you, you must use the Joint Life and Last Survivor Expectancy Table instead, which produces smaller RMDs. The calculator does not handle inherited IRAs, which follow different distribution rules under the SECURE Act and SECURE 2.0. It does not account for after-tax contributions to your traditional IRA, which reduce the taxable portion of your RMD. The projected 10-year schedule assumes a constant rate of return, but actual investment performance varies. For complex situations including multiple account types, inherited accounts, or the still-working exception, consult a tax professional or financial advisor.
