About Required Minimum Distributions
An RMD is the minimum amount the IRS requires you to withdraw each year from tax-deferred retirement accounts after a certain age. The government wants its tax revenue eventually - RMDs make sure you can't defer indefinitely.
Who must take RMDs:
- Traditional IRA, SEP IRA, SIMPLE IRA owners
- 401(k), 403(b), 457(b) participants (unless still working at sponsor company)
- Inherited IRA / 401(k) beneficiaries (different rules - 10-year rule for most)
Who doesn't need RMDs:
- Roth IRA owners (during their lifetime)
- Roth 401(k) owners (since 2024 - SECURE 2.0)
Starting age (SECURE Act 2.0):
- Age 73 if born 1951-1959 (turning 73 between 2024-2032)
- Age 75 if born 1960 or later (starts 2033)
Missed RMD penalty: 25% of the shortfall (reduced from 50% by SECURE 2.0). Drops to 10% if you correct within 2 years and file Form 5329.
How RMDs are calculated
- Take account balance from December 31 of prior year
- Look up your age in IRS Uniform Lifetime Table (Pub 590-B)
- Divide balance by the table's distribution period factor
- Withdraw at least that amount by Dec 31 (or April 1 next year for first RMD)
- Pay ordinary income tax on the withdrawal at your marginal rate
Example: $500K IRA, age 73 → distribution period 26.5 → RMD = $500,000 ÷ 26.5 = $18,868.
Worked example
Retiree, age 75, $750,000 in Traditional IRA, 22% federal tax bracket.
- Distribution factor for age 75: 24.6
- RMD: $750,000 ÷ 24.6 = $30,488
- Federal tax (22%): ~$6,707
- Net to retiree: ~$23,781
- If they skip the RMD: 25% penalty = $7,622 + still owe income tax
FAQs
Can I take more than the RMD?
Absolutely - RMD is a minimum, not a maximum. Many retirees take more in low-income years to "fill brackets" before Social Security or pension kicks in.
What if I have multiple IRAs?
Calculate RMD for each Traditional IRA separately, then take the total from any combination of your IRAs. 401(k)s are different - each plan must distribute its own RMD separately.
Still working past 73?
If you're still employed at the company sponsoring your 401(k), you can defer RMDs from that 401(k) until you retire (no 5%+ owners). This doesn't apply to IRAs - those still require RMDs at 73.
QCD (Qualified Charitable Distribution)?
Donate up to $108,000 (2025) directly from IRA to charity - counts toward RMD but not taxable income. Excellent strategy if you'd donate anyway. Reduces AGI = lower Medicare premiums and less Soc Sec taxation.
Inherited IRA RMDs?
Most non-spouse beneficiaries must drain inherited IRA within 10 years (SECURE Act). Annual RMDs may also be required for years 1-9 if original owner was already taking RMDs. Spouses can roll over to their own IRA.
How to use the RMD Calculator
The RMD Calculator is a browser-based tool that runs entirely on your device. Inputs you enter never reach a server - all calculations happen client-side in JavaScript. This means:
- Privacy: nothing is logged, sent, or stored by 3Tej. Inputs disappear when you close the tab.
- Speed: results update as you type. No network round trip.
- Offline use: once the page is cached, it works without internet.
- No signup: no account, no email, no rate limits.
Step by step
- Enter your inputs in the form above. Each field is labeled with its unit (currency, percent, kg, etc.) and the expected range.
- Read the result as it updates. The number reflects the formula commonly accepted in RMD-related calculations.
- Adjust to see sensitivity: change one input at a time and watch how the output moves. This is the fastest way to understand which variable matters most.
- Copy or screenshot the result for later reference. The page state persists for the session if your browser allows it.
When you would use this
- Quick estimates: when you need a number now and don't want to open a spreadsheet.
- Sensitivity analysis: testing how a result changes as inputs vary, before committing to a real-world decision.
- Comparison: running the same calculation with different inputs to compare options side by side.
- Learning: building intuition for how the underlying math behaves.
- Documentation: capturing a snapshot of inputs and outputs at a point in time.
Frequently asked questions
Is the RMD Calculator accurate?
The RMD Calculator applies the standard formula for rmd. Accuracy is limited only by your input precision. For decisions with material consequences, use the result as a starting point and verify with a qualified professional or the relevant official source.

Can I share results from the RMD Calculator?
Take a screenshot or copy the output. The page doesn't generate shareable URLs for specific calculations - inputs stay in your browser only.
Why are the results different from another rmd tool?
Most likely: different formula assumptions, different default values, different rounding rules, or different applicable rates. Check the methodology if both tools document it. Both can be valid for different scenarios.
Real-world scenarios where the RMD Calculator helps
Day-to-day decisions
Quick estimates without opening a spreadsheet. The RMD Calculator runs the math instantly so you can compare options, sanity-check assumptions, and move on.
Planning ahead
Build a forward-looking model. Change one variable at a time to see how sensitive the rmd output is to each input. The variable that moves the result most is where you should focus your real-world attention.
Cross-checking advisors
Compare what a professional or quoted source tells you against an independent calculation. Discrepancies are conversations worth having before signing.
Documentation
Capture inputs and outputs at a point in time. Screenshot the result with the date for audit trails, joint decisions, or future reference.
Learning intuition
By varying inputs, you build a sense of how rmd actually behaves. The numerical pattern teaches faster than reading prose.
Sensitivity analysis
Identify which input drives the result. The most-impactful variable is where small improvements pay off most.
Comparing alternatives
Run the same rmd calculation across multiple options and rank them by the dimension you care about (cost, return, speed, risk).
Pre-meeting preparation
Walk into a negotiation, sales call, or strategic discussion with the rmd numbers already in your head. Beats winging it from memory.
What the RMD Calculator does and does not handle
What it does
- Applies the standard formula widely accepted in rmd-related calculations.
- Updates instantly as you adjust inputs - useful for sensitivity analysis and what-if scenarios.
- Runs entirely in your browser using JavaScript. Your inputs never reach a server.
- Handles common edge cases (zero values, very large numbers, negative inputs where applicable) with sensible defaults or validation messages.
- Works offline once the page is cached. No internet needed for repeat calculations.
- Free, unlimited use. No signup, no rate limits, no paywall.
What it does not handle (and where to go)
- Personal financial advice - the calculation gives you a number, not a recommendation. Speak to a qualified advisor for decisions with significant financial consequences.
- Country-specific rules where local variation is high - the tool uses the most common methodology; some jurisdictions have variations.
- Real-time market data when applicable - most calculations use static reference values. Live market prices are out of scope.
- Auto-filling from external accounts - all inputs are manual. Browser autofill works for repeated entries.
- Saving results across devices - all state lives in this browser session.
Common mistakes and pitfalls
- Using rough estimates as inputs. Garbage in, garbage out. The RMD Calculator is only as accurate as what you type. Look up exact numbers from your statement, contract, or source document.
- Confusing units. Most fields are labeled (currency, percent, kg, etc.) but read the label before typing. A monthly figure entered into an annual field will be off by 12x.
- Ignoring the assumptions baked into the formula. Every calculator has assumptions (e.g., uniform growth rate, no fees, no taxes). Read the methodology section to understand what's included and what's not.
- Comparing without holding other variables constant. When testing options, change only ONE input at a time. Changing multiple inputs makes it impossible to tell which one drove the result.
- Treating the result as final. The output is a model. The real world adds fees, taxes, timing differences, and exceptions. Use the result as a starting point, not a final answer.
- Misreading rounded display. Most fields display 2 decimal places but compute at full precision. Two inputs that look identical may produce slightly different outputs.
Best practices for accurate results
- Pull exact values from authoritative sources (bank statement, payslip, official rate table, contract) rather than ballparking from memory.
- Match units carefully. Watch for monthly vs annual, gross vs net, percent vs basis points, USD vs INR.
- Run the calculation multiple times with slightly different inputs to see how sensitive the result is.
- Screenshot or note the inputs alongside the output for future reference - results change if rules or rates change.
- Cross-check against a professional source (advisor, accountant, official tool) for any decision with material impact.
- Update annually. Tax rates, contribution limits, and benefit thresholds change yearly. Rerun key calculations every January.
