This iras & roth calculator runs on standard retirement mathematics: contributions compound monthly, withdrawals are tested against growth, and every figure updates live as you type.

Estimate only

Uses the Uniform Lifetime Table. Your plan may use the Joint-and-Last-Survivor table, and Roth IRAs have no RMDs for the owner.

Formula

The Uniform Lifetime Table divisor for the age divides the balance; the quotient must leave the account that year.

RMD = prior year-end balance ÷ IRS distribution period

Explanation

The minimum the IRS forces out — and the balance that stays invested.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Look up the IRS Uniform Lifetime Table divisor for the age.

Factor from the Uniform Lifetime Table
Age:73
Result: 26.5-year divisor
Step 2

Divide the prior year-end balance by the divisor.

RMD = balance ÷ divisor
Balance:$500,000
Result: $18,868 required
Step 3

The remainder stays invested and compounds for next year’s calculation.

Remaining = balance − RMD
Result: $481,132 stays invested
Final Answer
$18,868

Scenario

The rmd calculator run on the values above, showing the full calculation path rather than only the answer.

Inputs

Account Balance:$500,000
Age at Distribution:73

Calculation

1. Look up the IRS Uniform Lifetime Table divisor for the age. → 26.5-year divisor 2. Divide the prior year-end balance by the divisor. → $18,868 required 3. The remainder stays invested and compounds for next year’s calculation. → $481,132 stays invested

Result

Required Minimum Distribution: $18,868

Interpretation

RMD $18,868 on $500,000 at age 73 (÷ 26.5).

Understanding Your Result

Your Result: Required Minimum Distribution: $18,868

What This Means

The minimum the IRS forces out — and the balance that stays invested.

Why It Matters

RMD $18,868 on $500,000 at age 73 (÷ 26.5).

Professional Interpretation

RMD $18,868 on $500,000 at age 73 (÷ 26.5).

How this is calculated

The Uniform Lifetime Table divisor for the age divides the balance; the quotient must leave the account that year.

What drives the result

Traditional accounts give a tax break now and tax withdrawals later; Roth accounts reverse it. The winner is decided almost entirely by your marginal rate today versus in retirement — everything else is detail.

Recommendations

  • •Take the RMD before December 31 — the penalty for missing it is severe.
  • •If you do not need the cash, do a qualified charitable distribution straight from the IRA.

Educational Content

Introduction

The US retirement system is a menu of tax wrappers — 401(k)s, Traditional and Roth IRAs — each with its own contribution limits, match rules, distribution requirements and conversion options. Every figure on this page prices those rules: matches captured, taxes due, RMDs owed, and which wrapper wins at your tax rates.

Concept Explanation

Traditional accounts give a tax break now and tax withdrawals later; Roth accounts reverse it. The winner is decided almost entirely by your marginal rate today versus in retirement — everything else is detail.

Applications

▸Capturing the full 401(k) employer match before saving anywhere else
▸Choosing Roth vs Traditional contributions at your current bracket
▸Timing Roth conversions and RMDs to smooth lifetime taxes

Benefits

  • •Puts a dollar value on the employer match and on unclaimed match money
  • •Shows conversion tax today versus tax saved tomorrow in one comparison
  • •Uses IRS table factors for RMDs so the number matches your statement

Limitations

  • •Uses single flat tax rates — real filings blend brackets, states and Social Security rules
  • •Ignores contribution and income limits that phase out deductions and Roth eligibility
  • •RMD factors follow the Uniform Lifetime Table; some plans use different tables
  • •Estimate only: Uses the Uniform Lifetime Table. Your plan may use the Joint-and-Last-Survivor table, and Roth IRAs have no RMDs for the owner.

Best Practices

  • •Contribute to the 401(k) match cap first, then max an IRA, then return to the 401(k)
  • •Pay conversion tax from taxable cash, never from the converted balance
  • •Run Roth conversions in low-income windows: job gaps, sabbaticals, early retirement

Common Misconceptions

Myth: A 401(k) loan is free money since I pay myself interest.
Truth: The interest is double-taxed and the borrowed sum misses market growth — the true cost is the lost compounding.
Myth: Roth is always better than Traditional.
Truth: At a much lower retirement rate, Traditional wins; the answer flips with brackets, which is why most people should hold both.

Practical Tips

  • •Take RMDs before December to avoid year-end chaos.
  • •Donate RMDs directly as QCDs if charity is in the plan.

Common Mistakes

Using the wrong table.
Most owners use Uniform Lifetime; beneficiaries and younger-spouse cases differ.
Forgetting Roth IRAs have no owner RMDs.
Only pre-tax balances force distributions.

Assumptions

This calculator makes the following assumptions to provide estimates:

Uniform Lifetime Table: Standard-owner factors; special cases need their own table.

Limitations

Be aware of these limitations when using this calculator:

Limitation: Uses single flat tax rates — real filings blend brackets, states and Social Security rules
Limitation: Ignores contribution and income limits that phase out deductions and Roth eligibility
Limitation: RMD factors follow the Uniform Lifetime Table; some plans use different tables

Frequently Asked Questions

Answers to common questions about this calculator.

How is my RMD calculated?
Balance divided by the Uniform Lifetime Table factor for your age — e.g. $500K ÷ 26.5 ≈ $18,868 at 73.
What if I miss an RMD?
Penalties are severe (up to 25%, plus interest) — automate December withdrawals with a buffer.
Who uses the rmd calculator?
It is used by savers planning their IRA, by advisers modelling retirement scenarios before clients commit, and by near-retirees stress-testing income, taxes and timing. It sits in the IRAs & Roth group of the Retirement section of Atlascalcs.
How accurate is the rmd calculator?
Every figure follows directly from the inputs using standard retirement mathematics, so it is accurate to the quality of the values you enter. Markets compound unevenly and tax rules change, so treat smooth projections as planning guides and re-run yearly with actual balances.
How accurate is the RMD Calculator?
Every figure follows directly from your inputs using standard retirement mathematics, so accuracy depends on the quality of the return, inflation and spending assumptions you enter. Markets, taxes and life events will differ from any smooth projection.
Should I use nominal or real returns in the RMD Calculator?
Enter nominal (before-inflation) returns — the page converts to real purchasing power internally wherever the IRA math needs it, and shows today’s-dollar equivalents alongside nominal figures.
