How This Works
When you reach a certain age, the IRS requires you to start withdrawing money from your tax-deferred retirement accounts. These withdrawals are called Required Minimum Distributions, or RMDs. Think of it as the government saying, “You’ve delayed paying taxes long enough—now it’s time to start taking money out so we can collect our share.”
What age do RMDs start?
Your starting age depends on when you were born. If you were born between 1951 and 1959, you must begin taking RMDs at age 73. Were you born in 1960 or later? Your RMD age is 75. This changed recently with the SECURE Act 2.0, which pushed back the RMD age to give retirees more flexibility.
The calculation behind your RMD
The IRS doesn’t just pick a random number. Your RMD is calculated by dividing your account balance from December 31 of the previous year by a “life expectancy factor” from IRS tables. This factor gets smaller each year as you age, meaning you’ll need to withdraw a larger percentage of your account over time.
Step-by-Step Guide
Let’s walk through exactly how to use this calculator and what happens next.
Gather your account information
You’ll need your retirement account statement from December 31 of last year. This shows your exact account balance that the IRS uses for RMD calculations. If you have multiple IRAs, you can add them together, but 401(k)s must be calculated separately.
Enter your details
Select your account type from the dropdown menu. Traditional IRAs and 401(k)s follow standard RMD rules, while inherited accounts have different requirements. Then input your birth year or current age—the calculator will figure out which IRS table applies to you.
Special situations
If your spouse is your sole beneficiary and more than 10 years younger than you, make sure to enter their age. This allows you to use the Joint Life Expectancy Table, which typically results in a lower RMD. Similarly, if you inherited an IRA, you’ll need to provide when the original owner passed away.
What to do with your results
Once you calculate your RMD, you have until December 31 to withdraw that amount. You can take it all at once or spread it throughout the year—just make sure you hit the total by year-end. Your first RMD gets a little extra time: you have until April 1 of the year after you turn 73 (or 75). But be careful, because you’ll still need to take your second RMD by December 31 of that same year.
Different Account Types Explained
Traditional IRA
The most straightforward case. You can calculate one total RMD for all your traditional IRAs combined, then withdraw that amount from one account or split it among several.
401(k) Plans
Each 401(k) must be calculated separately, and you must take the RMD from each specific account. You can’t combine them like you can with IRAs.
Inherited Accounts
Rules vary based on your relationship to the deceased and when they passed away. Spouses have the most flexibility, while non-spouse beneficiaries typically must empty the account within 10 years.
Roth IRAs
Good news here—original Roth IRA owners never have to take RMDs during their lifetime. However, beneficiaries who inherit Roth IRAs do have distribution requirements.
Which IRS Table Applies to You?
The IRS publishes three different life expectancy tables, and using the wrong one could cost you money. Here’s how to know which one you need.
| Your Situation | Table to Use | Why It Matters |
|---|---|---|
| Most account owners age 73+ | Uniform Lifetime Table | Standard table for typical situations, built into this calculator |
| Spouse sole beneficiary, 10+ years younger | Joint and Last Survivor Table | Lower RMDs because of longer joint life expectancy |
| You inherited an IRA | Single Life Expectancy Table | Different rules for beneficiaries vs. original owners |
Common Questions Answered
The penalty is steep—25% of the amount you should have withdrawn but didn’t. So if your RMD was $20,000 and you took nothing, you’d owe a $5,000 penalty on top of regular income taxes. The good news is that if you realize your mistake quickly and correct it, the IRS may reduce the penalty to 10%.
Absolutely. The RMD is just the minimum—you can always withdraw more if you need it. However, taking extra this year doesn’t give you credit for next year. Each year stands alone, and you can’t “bank” extra withdrawals for the future.
Yes, RMDs from traditional IRAs and 401(k)s are taxed as ordinary income. That’s because you got a tax deduction when you contributed the money, so now the IRS wants its share. Plan accordingly, especially if a large RMD could push you into a higher tax bracket.
Yes, through what’s called a Qualified Charitable Distribution (QCD). If you’re 70½ or older, you can transfer up to $105,000 directly from your IRA to a qualified charity. This satisfies your RMD without increasing your taxable income—a win-win if you’re charitably inclined.
If you’re still employed by the company that sponsors your 401(k) and you don’t own 5% or more of the business, you can delay RMDs from that specific 401(k) until you retire. However, you still must take RMDs from IRAs and 401(k)s from previous employers.
Contact your account custodian—the bank, brokerage, or financial institution holding your IRA or 401(k). Most allow you to set up automatic annual RMDs, which can prevent missed deadlines. You can take it as a lump sum or schedule monthly payments throughout the year.
The rules changed dramatically. Most non-spouse beneficiaries who inherited accounts after 2019 must empty the account within 10 years. You might also need to take annual RMDs during those 10 years if the original owner had already started taking RMDs. It’s complicated, so consider consulting a tax professional.
Avoiding Costly Mistakes
Even smart people make errors when it comes to RMDs. Here are the mistakes that trip people up most often.
Using last year’s balance incorrectly
Your RMD must be based on your account balance from December 31 of the previous year—not your current balance. If your account grew or shrank since then, that doesn’t matter for this year’s calculation. Using the wrong balance is one of the most frequent errors.
Forgetting about all your accounts
That old 401(k) from a job you left 15 years ago? It needs an RMD too if you’re old enough. Many people forget about accounts they opened decades ago. Make a complete list of all your retirement accounts to avoid missing one.
Miscalculating inherited IRAs
Inherited IRAs follow different rules than your own accounts. Non-spouse beneficiaries can’t just use the Uniform Lifetime Table. They need the Single Life Expectancy Table, and the calculation starts the year after the owner’s death.
Missing the April 1 deadline for first RMD
You get extra time for your very first RMD—until April 1 of the year after you turn 73 or 75. But here’s the trap: you’ll still owe your second RMD by December 31 of that same year. This means taking two RMDs in one calendar year, which could push you into a higher tax bracket.
Assuming Roth IRAs need RMDs
They don’t—at least not for the original owner. Roth IRAs are exempt from RMD requirements during your lifetime. But if you inherit a Roth IRA, different rules apply, and you may need to take distributions.
Planning Strategies
Smart retirees don’t just calculate their RMD at the last minute—they plan ahead to minimize taxes and maximize their retirement income.
Consider Roth conversions before RMDs start
If you’re 72 or younger, you might benefit from converting some traditional IRA money to a Roth IRA. You’ll pay taxes now, but that money won’t be subject to RMDs later. This strategy works best if you’re in a lower tax bracket now than you expect to be in the future.
Time your withdrawals strategically
You don’t have to take your RMD in December. Some retirees take it early in the year to lock in gains, while others wait to see how their accounts perform. If your account drops significantly during the year, your RMD stays the same—it’s based on last year’s balance.
Bunch your charitable donations
If you donate to charity anyway, using your RMD through a QCD can be tax-smart. The money goes directly from your IRA to the charity, satisfying your RMD without adding to your taxable income. This is especially valuable if you take the standard deduction and can’t itemize charitable donations.
Coordinate with Social Security
Large RMDs can increase your income enough to make more of your Social Security benefits taxable. You might also face higher Medicare premiums. If possible, try to keep your total income below the thresholds that trigger these additional costs.
2025 Updates and Changes
RMD rules keep evolving, and staying current helps you avoid mistakes and take advantage of new opportunities.
The IRS updated its life expectancy tables in 2022, generally lowering RMD amounts compared to the old tables. If you calculated RMDs before 2022 and are doing so again now, don’t be surprised if the percentage seems smaller—that’s the new tables at work.
For those born in 1960 or later, the RMD starting age increases to 75 in 2033. This gives younger retirees even more time to let their accounts grow tax-deferred. However, if you were born between 1951 and 1959, your RMD age is still 73.
Sample Calculations
Sometimes seeing actual numbers helps everything click. Here are three real-world scenarios.
Scenario 1: Standard traditional IRA
Maria is 75 years old with a traditional IRA worth $400,000 as of December 31, 2024. At age 75, her life expectancy factor is 24.6. Her RMD is $400,000 ÷ 24.6 = $16,260.16. She needs to withdraw at least this amount by December 31, 2025.
Scenario 2: Younger spouse beneficiary
Tom is 74, and his wife Susan is 62—making her 12 years younger. Tom’s 401(k) balance is $750,000. Because Susan is his sole beneficiary and more than 10 years younger, they use the Joint and Last Survivor Table. At ages 74 and 62, their factor is 26.5. Tom’s RMD is $750,000 ÷ 26.5 = $28,301.89.
Scenario 3: Inherited IRA
Jennifer inherited an IRA from her mother who passed away in 2024 at age 80. The account was worth $200,000. Jennifer is 55 years old. She uses the Single Life Expectancy Table, where her factor at 55 is 31.6. Her RMD for the first year is $200,000 ÷ 31.6 = $6,329.11. Each subsequent year, she subtracts 1 from the factor (30.6, then 29.6, and so on).
