RMD Calculator Starting at Age 75

This calculator estimates your Required Minimum Distribution (RMD) if you start taking withdrawals at age 75, based on your account balance and the IRS Uniform Lifetime Table. Enter your account balance and age, and you’ll get the annual amount you must withdraw. It uses the standard IRS divisor for your age, which is the most common method for unmarried owners.

Formula

The RMD is calculated by dividing your retirement account balance (as of December 31 of the previous year) by a life expectancy factor from the IRS tables. For age 75, the Uniform Lifetime Table divisor is 22.9.

RMD = Account Balance ÷ Divisor

• Account Balance – the fair market value of your IRA or retirement plan at the end of the prior year (in dollars).
• Divisor – the life expectancy factor from the IRS Uniform Lifetime Table, which depends on your age. For age 75, it is 22.9.

Worked Example

Using the default values: account balance = $500,000, age = 75.

1. Find the divisor for age 75 from the Uniform Lifetime Table: 22.9.
2. Divide the balance by the divisor: $500,000 ÷ 22.9 = $21,834.06.
3. Round to the nearest dollar: $21,834.

So, if you have $500,000 in your IRA at age 75, your RMD for the year is $21,834.

When Does the RMD Start at Age 75?

The SECURE 2.0 Act raised the age at which RMDs must begin. For anyone who turns 72 after December 31, 2022, the first RMD is required at age 73. However, if you turn 74 after December 31, 2032, the age increases to 75. This means that people born in 1960 or later will not have to start taking RMDs until they reach age 75. If you are already past the required beginning date, you must still take an RMD each year, and this calculator helps you figure out the amount for the current year.

How to Use This Calculator

Enter your account balance as of December 31 of the previous year. This includes all traditional IRAs, SEP IRAs, SIMPLE IRAs, and employer plans like 401(k)s and 403(b)s. If you have multiple IRAs, you can calculate the RMD for each separately, or combine them for the total. The calculator uses the Uniform Lifetime Table, which applies to most unmarried owners and married owners whose spouse is not more than 10 years younger. If your spouse is the sole beneficiary and is more than 10 years younger, you may use the Joint Life and Last Survivor Expectancy Table, which gives a lower RMD. This calculator does not account for that exception.

Common Mistakes and Misconceptions

A frequent mistake is using the current year’s balance instead of the prior year-end balance. The IRS requires you to use the account value on December 31 of the previous year. Another common error is forgetting to take the first RMD by April 1 of the year after you turn the required age. If you delay your first RMD to April 1, you must take two distributions that year (the first and the second), which can push you into a higher tax bracket. Also, note that the divisor decreases each year as you age, so the RMD amount generally increases even if your balance stays the same.

How to Read the Result

The result is the minimum amount you must withdraw from your retirement account each year. You can withdraw more than the minimum, but you cannot withdraw less without facing a 25% excise tax on the shortfall (reduced to 10% if corrected promptly). The withdrawal is subject to ordinary income tax. If you have multiple IRAs, you can take the total RMD from one account or split it among them, but for employer plans, the RMD must be taken from each plan separately.

Limitations and When to Consult a Professional

This calculator provides an estimate for the Uniform Lifetime Table only. It does not account for inherited IRAs, which use different tables, nor does it factor in the spousal exception mentioned earlier. The IRS updates the tables periodically, and the divisor for age 75 may change if new tables are issued. Always verify the current table on the IRS website or with a tax professional. For large balances, complex beneficiary situations, or if you are considering a Qualified Charitable Distribution (QCD), consult a tax advisor to ensure you meet all requirements.

Frequently Asked Questions

Can I start RMDs at 75 even if I turned 73 earlier?

No, if you have already reached your required beginning date (RBD), you must continue taking RMDs each year. The age increase applies only to those who are not yet subject to RMDs. If you turned 73 in 2024, you must take your first RMD by April 1, 2025, and annually thereafter.

What happens if I miss an RMD?

The IRS imposes an excise tax of 25% of the amount not withdrawn (10% if you correct the error within two years). You must file Form 5329 with your tax return to report the missed distribution and pay the tax. The sooner you correct it, the lower the penalty.

Does this calculator work for inherited IRAs?

No, inherited IRAs use different life expectancy tables (Single Life Expectancy or the 10-year rule). This calculator is only for your own retirement accounts. For inherited accounts, consult the IRS Publication 590-B or a tax professional.

Can I take my RMD in monthly installments?

Yes, you can take distributions throughout the year as long as the total by December 31 meets the annual requirement. Many people choose monthly or quarterly withdrawals to manage taxes and cash flow. Just be sure the total equals at least the RMD amount.

Is the RMD taxable?

Yes, RMDs are treated as ordinary income and are subject to federal income tax, and possibly state tax. If you have made after-tax contributions to your IRA, a portion may be tax-free, but this is rare. You can avoid taxes by donating up to $100,000 directly to a charity via a Qualified Charitable Distribution (QCD), which counts toward your RMD.
