Required Minimum Distribution (RMD) Calculator
Estimate your annual RMD using the IRS Uniform Lifetime Table (commonly used for traditional IRA and employer plan owners).
Educational estimate only. Special rules apply for inherited accounts, certain spouse beneficiary situations, and employer plans where you still work.
What is an RMD?
An RMD, or Required Minimum Distribution, is the minimum amount the IRS generally requires you to withdraw each year from tax-deferred retirement accounts such as traditional IRAs, SEP IRAs, SIMPLE IRAs, and many employer plans once you reach the applicable age.
The purpose is simple: these accounts received tax benefits over time, and eventually the IRS wants taxable distributions to begin.
How this RMD calculator works
This calculator uses the standard IRS formula:
RMD = Prior Year-End Account Balance ÷ Life Expectancy Divisor
The divisor comes from the IRS Uniform Lifetime Table (updated in 2022). For most account owners, this is the correct table.
Quick example
- Prior year-end balance: $500,000
- Age: 75
- Uniform Lifetime divisor at age 75: 24.6
- Estimated RMD: $500,000 ÷ 24.6 = $20,325.20
Who needs to take RMDs?
In general, RMD rules apply to most pre-tax retirement accounts. Roth IRAs for original owners typically do not require lifetime RMDs, but inherited Roth accounts can have distribution rules.
Common accounts impacted
- Traditional IRA
- SEP IRA
- SIMPLE IRA
- 401(k), 403(b), and similar employer plans
- Inherited retirement accounts (special timing rules apply)
RMD age and timing basics
Under current law, many people begin RMDs at age 73, with age 75 applying for younger birth cohorts. Your exact start age depends on birth year and account type, so always verify with current IRS guidance or your plan administrator.
Your first RMD can often be delayed until April 1 of the year after you are required to begin, but delaying can result in two taxable RMDs in one calendar year.
Tax impact and planning ideas
RMDs are generally taxed as ordinary income. Because of that, it helps to plan ahead.
Potential strategies to discuss with a professional
- Take distributions monthly or quarterly to smooth cash flow.
- Coordinate withdrawals with Social Security and other taxable income.
- Use withholding so you are not surprised at tax time.
- Consider Qualified Charitable Distributions (QCDs), if eligible.
- Review Roth conversion opportunities before RMD years.
Common RMD mistakes to avoid
- Using the wrong balance: RMD uses your account value as of December 31 of the previous year.
- Missing deadlines: Late or missed RMDs can trigger penalties.
- Confusing account rules: Inherited accounts and spouse scenarios can differ significantly.
- Ignoring tax withholding: A large year-end distribution may create a tax crunch.
Final thoughts
An RMD is straightforward in formula but nuanced in real life. This calculator gives you a practical estimate and helps you model your annual distribution amount. Use it as a planning tool, then confirm specifics with your custodian, CPA, or financial advisor before filing taxes or executing large withdrawals.
