Required Minimum Distribution (RMD) Calculator
Calculate your annual IRS-required distribution from 401(k), IRA, and other tax-deferred retirement accounts
Enter your details above and click Calculate to see your RMD breakdown.
RMDs apply to traditional IRAs, 401(k)s, 403(b)s, and other tax-deferred retirement accounts. Roth IRAs are not subject to RMDs during the owner's lifetime.
How to Use This Tool
Follow these steps to calculate your Required Minimum Distribution:
- Select your preferred currency from the dropdown menu.
- Enter the total balance of your tax-deferred retirement account as of December 31 of the prior year. This includes traditional IRAs, 401(k)s, 403(b)s, and similar accounts.
- Enter your current age for the year you plan to take the distribution. RMDs are mandatory starting at age 73.
- Select the appropriate life expectancy table: choose Uniform Lifetime Table if you are single or your spouse is not more than 10 years younger, or Joint Life and Last Survivor Table if your spouse is the sole beneficiary and more than 10 years younger than you.
- Click the Calculate RMD button to see your detailed distribution breakdown.
- Use the Reset button to clear all inputs and start over, or Copy Results to Clipboard to save your breakdown.
Formula and Logic
The IRS calculates RMDs using a simple formula:
RMD = Prior Year End Account Balance ÷ Life Expectancy Factor
The life expectancy factor is determined by the IRS based on your age and filing status, published in IRS Publication 590-B. This tool uses the official 2024 IRS Uniform Lifetime Table and Joint Life and Last Survivor Table factors for calculations.
For ages not explicitly listed in the tables (over 100), the tool extrapolates factors by decreasing the age 100 factor by 0.4 per additional year, which aligns with IRS guidance for advanced ages.
Practical Notes
Keep these real-world finance considerations in mind when planning your RMDs:
- Roth IRAs are not subject to RMDs during the original owner's lifetime. Roth 401(k)s are subject to RMDs, but you can roll them into a Roth IRA to avoid this.
- If you fail to withdraw the full RMD amount by the deadline, you may be subject to a 25% excise tax on the shortfall (reduced to 10% if corrected within 2 years).
- Your first RMD can be delayed until April 1 of the year after you turn 73, but all subsequent RMDs must be taken by December 31. Delaying your first RMD will result in two distributions in the same tax year, which may push you into a higher tax bracket.
- RMDs are taxed as ordinary income in the year they are withdrawn. Plan for the tax liability to avoid underpayment penalties.
- You can withdraw more than the RMD amount, but you cannot count excess withdrawals toward future years' RMDs.
Why This Tool Is Useful
This calculator simplifies IRS RMD compliance for a wide range of users:
- Retirees can quickly verify their annual distribution requirement without manually looking up life expectancy factors.
- Financial planners can use the detailed breakdown to advise clients on tax planning and retirement income strategies.
- Account holders approaching age 73 can project future RMDs to adjust their savings and withdrawal plans.
- The tool includes both common life expectancy tables, eliminating the need to cross-reference IRS publications for most users.
- Copy-to-clipboard functionality makes it easy to share results with tax professionals or keep records.
Frequently Asked Questions
What accounts are subject to RMDs?
RMDs apply to all tax-deferred retirement accounts, including traditional IRAs, SEP IRAs, SIMPLE IRAs, 401(k)s, 403(b)s, 457(b) plans, and profit-sharing plans. Roth IRAs are exempt during the owner's lifetime, and Roth 401(k)s can be rolled into Roth IRAs to avoid RMDs.
Can I aggregate RMDs from multiple accounts?
You can aggregate RMDs for IRAs: calculate the total RMD for all your IRAs, then withdraw the full amount from one or more IRAs. For employer-sponsored plans like 401(k)s, you must calculate and withdraw RMDs separately for each plan, unless the plan allows aggregation.
What if I turn 73 later in the year?
Your RMD age is based on your age as of December 31 of the distribution year. If you turn 73 in November 2024, you are required to take an RMD for the 2024 tax year.
Additional Guidance
Consider these additional tips for managing your RMDs:
- Set up automatic withdrawals from your retirement accounts to ensure you never miss an RMD deadline.
- If you do not need the RMD funds for living expenses, consider reinvesting the withdrawal in a taxable brokerage account to keep your money growing.
- Work with a tax professional to coordinate RMDs with other income sources to minimize your overall tax burden.
- Review your RMD calculation annually, as your life expectancy factor decreases (and RMD amount increases) as you age.
