What this inherited IRA RMD calculator does

This page helps you estimate annual withdrawals from an inherited IRA. The calculator supports the two most common frameworks people ask about:

  • Life expectancy method (often used by eligible designated beneficiaries in specific cases)
  • 10-year rule for many non-spouse beneficiaries under SECURE Act-era rules

It gives you a practical withdrawal number for the current year and, when relevant, reminds you about the year-10 full distribution deadline.

Quick inherited IRA RMD rule refresher

1) Life expectancy method

Under this approach, annual RMD is generally calculated as:

RMD = Prior year-end balance / applicable life expectancy factor

You must use the correct IRS divisor for your beneficiary type and year. If you input the right factor, this calculator returns the matching dollar estimate.

2) 10-year rule (owner died before RBD)

If the original owner died before the required beginning date (RBD), many beneficiaries have no strict annual RMD in years 1-9, but the account must be emptied by the end of year 10.

The calculator therefore shows:

  • Required amount this year (often $0 before year 10)
  • A level-withdrawal suggestion so you can avoid a giant year-10 tax hit

3) 10-year rule (owner died on/after RBD)

In this scenario, annual withdrawals may apply in years 1-9 in addition to the year-10 emptying requirement. The calculator estimates the current year amount using your divisor and flags the year-10 rule.

How to use this calculator correctly

  1. Enter your inherited IRA prior December 31 balance.
  2. Select the distribution method matching your account type and beneficiary status.
  3. Enter the current tax year.
  4. If using a 10-year method, enter the original owner’s year of death.
  5. If your method needs a divisor, enter your distribution factor.
  6. Click Calculate RMD.

If you are unsure which divisor to use, check the current IRS guidance and your custodian’s inherited IRA notice. A single wrong factor can materially change the distribution amount.

Example scenarios

Example A: Life expectancy method

Balance: $300,000. Factor: 25.0. Estimated RMD: $12,000.

Example B: 10-year rule, owner died before RBD

Balance: $180,000, current year still before year 10. Mandatory annual RMD may be $0, but a level strategy could suggest spreading distributions over remaining years.

Example C: 10-year rule, owner died on/after RBD

Balance: $400,000, factor: 22.0. Estimated annual RMD: about $18,181.82, while still tracking the final depletion deadline at year 10.

Common inherited IRA mistakes to avoid

  • Missing the year-10 deadline and assuming year 1-9 withdrawals were enough.
  • Using the wrong life expectancy table or wrong divisor year.
  • Forgetting that inherited Roth IRAs can still have beneficiary distribution rules.
  • Ignoring tax-bracket planning and taking everything in one high-income year.
  • Assuming all beneficiaries follow the same rules (spouse, minor child, trust, and non-eligible beneficiaries differ).

Planning tips to reduce tax friction

  • Model multi-year withdrawals instead of waiting for year 10.
  • Coordinate inherited IRA withdrawals with Social Security timing and Medicare IRMAA thresholds.
  • Review state tax impact before taking large lump sums.
  • Re-check annual guidance as inherited IRA regulations continue to evolve.

FAQ

Does this calculator file taxes for me?

No. It is an estimate tool only.

Can I use this for spouse rollovers?

Not directly. Spousal options can include treating the IRA as your own, which follows different RMD mechanics.

Is the result guaranteed to match my custodian?

Not always. Custodians apply specific account records, beneficiary designations, and regulatory interpretation. Use this as a planning estimate and verify before year-end.
