Inherited Individual Retirement Accounts (IRAs) come with specific rules regarding Required Minimum Distributions (RMDs). If you’ve inherited an IRA, understanding how much you’re required to withdraw each year is essential for staying compliant with IRS regulations—and avoiding unnecessary penalties. That’s where our Inherited IRA Minimum Distribution Calculator comes in.

Example: Using the Calculator in Practice
Let’s say you inherited an IRA with a balance of $150,000. You’re 45 years old and according to the IRS Single Life Expectancy Table, your distribution factor is 38.8.
Here’s how it works:
- Enter
$150,000
in the IRA Balance field. - Enter
38.8
in the Distribution Factor field. - Click “Calculate”.
✅ Result: Your minimum distribution for the year would be $3,865.98.
This tells you how much you must withdraw this year to meet IRS requirements.
Understanding the IRS Distribution Factor
The distribution factor is a number provided by the IRS based on the beneficiary’s life expectancy. It’s designed to calculate how long the funds will last if only the required minimum is withdrawn each year.
- Younger beneficiaries have larger factors, which result in smaller withdrawals.
- Older beneficiaries have smaller factors, leading to larger required withdrawals.
The factor is often pulled from one of three tables:
- Single Life Expectancy Table – Used by most non-spouse beneficiaries.
- Uniform Lifetime Table – For account owners or spouse beneficiaries who treat the IRA as their own.
- Joint Life and Last Survivor Table – Rarely used for inherited IRAs.
Always consult IRS Publication 590-B for the correct table and values.
Why Is Calculating RMDs Important?
If you fail to take the required distribution—or withdraw less than you should—the IRS imposes a 50% penalty on the amount you should have withdrawn. For example, if your RMD is $5,000 and you only take out $2,000, you could owe $1,500 in penalties.
Properly calculating and taking your RMD helps you:
- Avoid penalties
- Stay compliant with tax law
- Strategically plan your retirement income
Use Cases: Who Should Use This Calculator?
- Non-spouse beneficiaries who inherited an IRA before the SECURE Act's 10-year rule came into effect.
- Spouses who opt not to roll the account into their own.
- Trusts or estates as IRA beneficiaries, especially when using life expectancy methods.
- Financial planners helping clients determine annual distribution amounts.
- Executors or administrators managing estate disbursements.
