How this calculator works
Use the explanation to understand the formula, assumptions, and practical limits behind the calculator result.
What Does This Calculator Estimate?
This calculator estimates the annual required minimum distribution (RMD) using the IRS Uniform Lifetime Table for ages 73 and above. It divides the prior-year-end account balance by the distribution period associated with the age entered.
RMD Formula
Where:
- = required minimum distribution
- = prior-year-end account balance
- = distribution period from the applicable IRS table
Practical Example
For an account balance of 500,000 USD at age 73, the Uniform Lifetime Table factor used by this calculator is 26.5.
| Item | Amount |
|---|---|
| Prior-year-end balance | 500,000 USD |
| Distribution period | 26.5 |
| Estimated annual RMD | about 18,867.92 USD |
| Monthly equivalent | about 1,572.33 USD |
Important Eligibility And Timing Caveat
The calculator estimates the amount once an RMD is due. It is not a full first-RMD-year eligibility checker. The IRS generally requires the first RMD by April 1 of the year after the year you reach age 73, with later annual RMDs due by December 31. Taking the first withdrawal in the following year can mean two RMDs fall into the same tax year.
What This Calculator Does Not Handle
- Inherited-account rules
- Spouse-beneficiary table exceptions
- Roth IRA lifetime treatment
- Multiple-account aggregation rules
- Whether a workplace-plan still-working exception applies
Why the Result Matters
If required withdrawals are missed or too small, the IRS may impose an excise tax on the shortfall. Use the calculator for planning, then confirm the exact account type, due date, and table with the plan custodian or a qualified tax professional.
Frequently asked questions
Which balance should I enter for an RMD?
Use the account balance from the end of the previous calendar year, because that is the balance the Uniform Lifetime Table formula applies to for the current year's RMD.
Does this tell me whether I must take an RMD this year?
No. It estimates the amount for someone already using the Uniform Lifetime Table. First-year timing, inherited accounts, spouse exceptions, and account type can change the rule that applies.
What happens if I miss an RMD?
The IRS states that insufficient distributions may trigger a 25% excise tax on the shortfall, reduced to 10% when corrected within the allowed period. Because timing and relief rules matter, confirm a missed distribution with a tax professional quickly.
Do Roth IRAs require lifetime RMDs?
Original Roth IRA owners do not have lifetime RMDs, but inherited Roth accounts follow separate beneficiary rules. Do not use this calculator as a substitute for inherited-account guidance.
