inherited ira distribution calculator

If you're searching for an inherited IRA RMD calculator, a 10-year rule IRA calculator, or an IRA beneficiary distribution schedule, you're in the right place. Inherited IRA rules can feel confusing, especially after the SECURE Act changed many timelines. This page helps you estimate withdrawals and understand how distribution choices affect taxes and account longevity.

How inherited IRA distributions work

An inherited IRA is a retirement account passed to a beneficiary after the original owner dies. The distribution rules depend on who inherited the account and whether the original owner had already begun required minimum distributions (RMDs).

Most non-spouse beneficiaries: the 10-year rule

For many beneficiaries, current law requires the inherited IRA to be fully distributed by the end of the 10th year after death. In some cases, annual RMDs may also apply during years 1-9 (especially if the decedent had already started RMDs), but the key point is that the balance typically must be zero by year 10.

• You can often choose timing: equal annual withdrawals, larger withdrawals in later years, or custom amounts.
• Tax impact can vary significantly depending on distribution timing.
• Higher withdrawals in peak earning years can create avoidable tax drag.

Eligible designated beneficiaries: life expectancy method

Certain beneficiaries may use life expectancy-based distributions (often called “stretch” treatment), such as:

• Surviving spouses (with additional options)
• Minor children of the account owner (until majority, then usually 10-year rule)
• Disabled or chronically ill beneficiaries
• Beneficiaries not more than 10 years younger than the decedent

Under this approach, the annual RMD generally starts by dividing the prior year-end balance by an IRS life expectancy factor, then reducing the factor by 1 each year.

What this inherited IRA distribution calculator does

1) 10-year level withdrawal estimate

The calculator computes a level annual withdrawal amount that would deplete the account over your selected remaining years, considering your expected annual return. It also shows estimated taxes and after-tax cash flow.

2) Life expectancy projection

You can enter your initial IRS life expectancy factor and project annual RMD-style withdrawals. This is useful for planning and comparing scenarios before filing distributions.

3) Year-by-year table output

The output includes starting balance, growth, distribution, estimated tax, and ending balance for each year so you can see the full path of the inherited IRA over time.

How to use this calculator effectively

• Start with your most recent inherited IRA statement balance.
• Use a conservative long-term return estimate (for example, 4% to 6%).
• Enter your current marginal tax rate for a quick tax estimate.
• Test multiple scenarios: equal withdrawals vs. heavier later-year withdrawals.
• Coordinate timing with Social Security, Roth conversions, and Medicare IRMAA thresholds when relevant.

Common inherited IRA planning mistakes

Waiting too long to plan

Many beneficiaries delay withdrawals until late in the 10-year window, then face large taxable distributions in one or two years.

Ignoring annual income stacking

Inherited IRA distributions can push other income into higher brackets. Strategic spreading can reduce lifetime taxes.

Using the wrong beneficiary rule

Not all beneficiaries follow the same timeline. Determine whether you are subject to the 10-year rule, life expectancy treatment, or another special case.

Important notes before you act

This calculator is an educational estimate, not official tax or legal advice. Actual inherited IRA distribution requirements depend on account type (traditional vs. Roth), beneficiary classification, year of death, and current IRS guidance. Always confirm your required minimum distribution obligations with your custodian, tax professional, or estate attorney.
