RMD Calculator

What is RMD (Required Minimum Distribution)?

Required Minimum Distributions (RMDs) are mandatory withdrawals that the IRS requires you to take annually from tax-deferred retirement accounts once you reach a certain age. The government allowed your investments to grow tax-deferred for decades, and RMDs ensure they eventually collect taxes on those funds. RMDs apply to traditional IRAs, 401(k)s, 403(b)s, and other qualified retirement plans, but not to Roth IRAs while the owner is alive.

The RMD amount is calculated by dividing your account balance as of December 31 of the prior year by a life expectancy factor from IRS tables. This factor decreases as you age, meaning you must withdraw a larger percentage of your remaining balance each year. Failing to take your full RMD results in a steep penalty of 25% of the amount not withdrawn, though this may be reduced to 10% if corrected promptly.

How to Use This Calculator

Step 1: Enter your current age at the end of the calendar year.
Step 2: Input your retirement account balance as of December 31 of last year.
Step 3: Select your account type (Traditional, Roth 401k, or Inherited).
Step 4: If married and your spouse is more than 10 years younger, enter their age.
Step 5: Click "Calculate" to see your required distribution amount.
Step 6: Plan your withdrawal strategy before the annual deadline.

RMD Calculation Examples

Example 1 - Standard RMD: At age 73 with a $500,000 traditional IRA balance, using the Uniform Lifetime Table factor of 26.5, your RMD would be $18,868 ($500,000 ÷ 26.5). This amount is fully taxable as ordinary income and must be withdrawn by December 31. Subsequent years use progressively smaller distribution periods, increasing the percentage that must be withdrawn.

Example 2 - Younger Spouse: At age 75 with a $400,000 balance and a spouse age 65 (10+ years younger), you can use the Joint Life and Last Survivor Expectancy table. The factor might be 28.7 instead of 22.9, resulting in a lower RMD of $13,937 instead of $17,467. This provision helps preserve assets when there's a significant age difference between spouses.

Example 3 - Inherited IRA: An inherited IRA from a parent who died after 2019 requires full distribution within 10 years under the SECURE Act. However, if the beneficiary is an eligible designated beneficiary (spouse, minor child, disabled, chronically ill, or not more than 10 years younger), they can stretch distributions over their life expectancy, taking smaller annual RMDs.

RMD Rules and Deadlines

• Age 73 Rule: RMDs must begin by April 1 of the year after you turn 73 (if born 1951-1959).
• Age 75 Rule: Those born 1960 or later start RMDs at age 75.
• First Year Deadline: First RMD can be delayed until April 1 of the following year, but then two RMDs in one year.
• Annual Deadline: All subsequent RMDs must be taken by December 31 each year.
• Still Working Exception: If working past RMD age with current employer 401k, may delay until retirement.
• Roth 401k: RMDs required from Roth 401k, but not from Roth IRA (while owner lives).
• Multiple Accounts: Calculate RMD for each IRA separately, but can withdraw total from one IRA.
• 401k Aggregation: Must take RMD separately from each 401k account (cannot aggregate).
• Penalty: Failure to take RMD results in 25% excise tax on amount not distributed.
• Penalty Reduction: Correct missed RMDs promptly—penalty may be reduced to 10%.
• Qualified Charitable Distributions: QCDs up to $105,000 can satisfy RMDs tax-free.
• Inherited IRAs: 10-year rule for most non-spouse beneficiaries; no annual RMDs required but full distribution by year 10.

RMD Strategies and Tips

• Don't Delay First RMD: Taking two RMDs in one year could push you into higher tax bracket.
• Consider Roth Conversions: Convert traditional IRA to Roth before RMD age to reduce future RMDs.
• Qualified Charitable Distributions: Use QCDs to satisfy RMDs tax-free while supporting charities.
• Consolidate Accounts: Fewer accounts make RMD calculations and management easier.
• Coordinate with Social Security: Time RMDs to minimize taxation of Social Security benefits.
• Tax Withholding: Consider having taxes withheld from RMDs to avoid quarterly estimates.
• Reinvest if Not Needed: Move unwanted RMDs to taxable brokerage account to stay invested.
• Review Beneficiaries: Ensure inherited IRA rules are understood by beneficiaries.
• Mark Calendar: Set reminders for December 1 to ensure RMDs are completed timely.
• Calculate Annually: Distribution period changes each year—recalculate every December.
• Coordinate with Spouse: Consider joint tax bracket when planning withdrawal timing.
• Life Expectancy Tables: Use correct table—Uniform Lifetime for most, Joint Life if spouse 10+ years younger.
• IRA Aggregation: Can take total IRA RMD from one account if multiple IRAs exist.
• Plan Early: Don't wait until December—market volatility could affect account balances.
