This RMD calculator helps individuals estimate their annual required minimum distribution from traditional IRAs and retirement accounts. It’s designed for anyone age 72+ who needs to calculate mandatory withdrawals to avoid IRS penalties.
Financial planners and retirees use this tool to budget for tax obligations and plan sustainable withdrawal strategies across multiple accounts.
Enter your account balance and age to see exactly how much you must take out this year, with breakdowns by account type and tax implications.
RMD Calculator
Calculate your required minimum distribution for traditional IRAs, 401(k)s, and other retirement accounts
How to Use This Tool
Enter your total balance across all traditional IRAs, 401(k)s, and other subject retirement accounts as of December 31 of the previous year. Input your age as of December 31 of the current year for which you're calculating the RMD. If you're married and your spouse is more than 10 years younger than you and is the sole beneficiary of your accounts, select the Joint Life table and enter your spouse's age. Click Calculate to see your total RMD amount, the life expectancy factor used, and which IRS table applies.
Formula and Logic
The RMD is calculated by dividing your account balance (as of the previous year-end) by your life expectancy factor from the appropriate IRS Uniform Lifetime Table or Joint Life and Last Survivor Expectancy Table. The formula is: RMD = Account Balance ÷ Life Expectancy Factor. The life expectancy factor decreases as you age, causing your RMD to increase over time even if your account balance remains constant. For multiple accounts, you can calculate the RMD per account using the same factor, but you may aggregate balances across like accounts (e.g., all traditional IRAs) and take the total from one account.
Practical Notes
RMDs apply to traditional IRAs, 401(k)s, 403(b)s, and most other tax-deferred retirement accounts. Roth IRAs are not subject to RMDs during the original owner's lifetime. You must take your first RMD by April 1 of the year after you turn 72 (or 70½ if you reached that age before 2020), but subsequent RMDs are due by December 31 each year. Taking your RMD from one account satisfies the requirement for all accounts of the same type. Consider tax withholding to avoid underpayment penalties. If you're still working and don't own 5% of the business, you may delay RMDs from your current employer's 401(k) until retirement.
Why This Tool Is Useful
This calculator removes the complexity of manually looking up IRS tables and performing division, providing instant, accurate RMD estimates. It helps retirees budget for the additional taxable income and avoid the steep 25% penalty (potentially 50% if not corrected) for missed RMDs. Financial planners use it to model withdrawal strategies across multiple accounts and years, optimizing tax efficiency. The breakdown by account type and clear display of the life expectancy factor aids in understanding how RMDs grow over time, supporting long-term financial planning.
Frequently Asked Questions
What happens if I miss my RMD deadline?
The IRS imposes a 25% penalty on the amount that should have been withdrawn but wasn't. This can increase to 50% if you don't correct the shortfall in a timely manner. You must file Form 5329 with your tax return and may request a waiver if you can show reasonable error and reasonable cause.
Can I take my RMD from any account?
For multiple accounts of the same type (e.g., several traditional IRAs), you can calculate the RMD for each account separately but take the total aggregated amount from any one or combination of those IRAs. For 401(k)s, you must take the RMD from each 401(k) account separately—you cannot aggregate across different 401(k) plans.
Do RMDs affect my Social Security taxation?
Yes. RMDs increase your adjusted gross income, which can cause a higher portion of your Social Security benefits to become taxable. Up to 85% of Social Security benefits may be taxable depending on your combined income (AGI + nontaxable interest + half of Social Security). Plan RMDs with other income sources to manage tax brackets.
Additional Guidance
Always verify your calculations with the latest IRS Publication 590-B, as tables and rules can change. For inherited IRAs (beneficiaries), different rules apply—use the Single Life Expectancy Table for most nonspouse beneficiaries. Consider qualified charitable distributions (QCDs) if you're charitably inclined; up to $100,000 can be transferred directly from your IRA to charity and count toward your RMD without being included in taxable income. State tax rules may differ; some states exempt retirement income. Consult a tax professional for complex situations involving multiple account types, inherited accounts, or if you're subject to state RMD-like rules.
