Introduction
A Required Minimum Distribution (RMD) is the smallest amount of money you must withdraw from your retirement account each year once you reach a certain age. The IRS requires these withdrawals from accounts like traditional IRAs and 401(k)s so they can collect taxes on money that has been growing tax-free. If you don't take out enough, you could face a big penalty of up to 25% of the amount you missed.
Our RMD Calculator helps you figure out exactly how much you need to withdraw each year. Just enter your account balance, your age, and a few other details, and the calculator works out the amount. It uses the IRS Uniform Lifetime Table to divide your account balance by your life expectancy factor, giving you an accurate RMD amount. This tool makes it simple to stay on track with your withdrawals and avoid costly mistakes during retirement.
How to Use Our RMD Calculator
Enter your retirement account details, date of birth, and optional tax information below. The calculator will determine your Required Minimum Distribution (RMD) amount, show estimated taxes, and project your RMDs and account balance over time.
Retirement Account Balance as of Dec 31 of Last Year: Enter the total value of your retirement account as of December 31 of the prior year. If you have more than one account of the same type, enter the combined total of all those accounts.
Account Type: Select the type of retirement account you hold, such as a Traditional IRA, 401(k), 403(b), 457(b), or other employer-sponsored plan. Different account types may follow slightly different RMD rules.
Calculation Year: Choose the year you want to calculate your RMD for. This is usually the current year.
Date of Birth: Enter your month, day, and year of birth. The calculator uses this to find your age at the end of the calculation year, which determines the IRS life expectancy factor used in the RMD formula.
Sole Beneficiary Is a Spouse More Than 10 Years Younger: Check this box if your only beneficiary is your spouse and they are more than 10 years younger than you. This applies a different IRS life expectancy table that lowers your RMD. If you check this box, enter your spouse's date of birth as well.
Expected Annual Growth Rate: Enter the rate of return you expect your retirement account to earn each year. This is used to project your future account balances and RMDs over the chosen projection period.
Estimated Federal Tax Rate: Enter your estimated marginal federal income tax rate. The calculator uses this to show how much of your RMD may go toward federal taxes.
Estimated State Tax Rate: Enter your estimated state income tax rate. If your state does not have an income tax, set this to zero.
Projection Period: Choose how many years into the future you want to project your RMDs and account balance. Options range from 5 to 30 years.
What Is a Required Minimum Distribution (RMD)?
A Required Minimum Distribution, or RMD, is the smallest amount of money the IRS says you must withdraw from your tax-deferred retirement accounts each year once you reach a certain age. These accounts include Traditional IRAs, 401(k)s, 403(b)s, and 457(b) plans. Because you never paid income tax on the money going into these accounts, the government requires you to start taking money out, and paying taxes on it, during retirement.
When Do RMDs Start?
The age at which you must begin taking RMDs depends on when you were born. Under the SECURE 2.0 Act, the rules are:
- Born in 1950 or earlier: RMDs started at age 72 (these individuals are already taking distributions).
- Born 1951–1959: RMDs begin at age 73.
- Born 1960 or later: RMDs begin at age 75, starting in 2033.
If it is your very first RMD year, you can delay that first withdrawal until April 1 of the following year. However, doing this means you must take two RMDs in one year (the delayed first-year distribution plus the current year's distribution), which could push you into a higher tax bracket.
How Is an RMD Calculated?
The formula for calculating your RMD is straightforward:
RMD = Account Balance (as of December 31 of the prior year) ÷ IRS Life Expectancy Factor
The IRS provides life expectancy factors in published tables. Most people use the Uniform Lifetime Table (Table III). For example, a 75-year-old has a life expectancy factor of 24.6. If that person had $500,000 in their Traditional IRA at the end of last year, their RMD would be $500,000 ÷ 24.6 = $20,325.20.
There is one important exception. If your sole beneficiary is your spouse and they are more than 10 years younger than you, the IRS lets you use the Joint and Last Survivor Table (Table II). This table gives a larger life expectancy factor, which means a smaller required withdrawal. This can be a helpful way to keep more money growing tax-deferred in your account.
What Happens If You Miss Your RMD?
Failing to take your full RMD on time comes with a steep penalty. Under the SECURE 2.0 Act, the IRS charges a 25% excise tax on the amount you should have withdrawn but didn't. This was reduced from the previous 50% penalty. If you catch and correct the mistake within the IRS correction window, the penalty drops further to 10%. Either way, it is a costly error that is easy to avoid with proper planning.
RMDs and Taxes
RMD withdrawals are treated as ordinary income for tax purposes. That means they are added to your other income for the year and taxed at your federal (and possibly state) income tax rate. This is important to keep in mind because a large RMD could push you into a higher tax bracket, increase the taxes on your Social Security benefits, or raise your Medicare premiums through IRMAA surcharges.
Tips for Managing Your RMDs
- Qualified Charitable Distributions (QCDs): If you are 70½ or older, you can donate up to $105,000 per year directly from your IRA to a qualified charity. This counts toward your RMD but is not included in your taxable income.
- Spread withdrawals across the year: Instead of taking one lump sum, consider monthly or quarterly distributions to manage cash flow and tax withholding.
- Plan ahead with Roth conversions: Converting some Traditional IRA funds to a Roth IRA before RMDs begin can reduce future required distributions since Roth IRAs have no RMDs during the owner's lifetime.
- Combine accounts if allowed: If you have multiple IRAs, you can add up all the RMD amounts and take the total from one or more of them. However, 401(k) RMDs must generally be taken separately from each plan.
Understanding your RMD is an important part of retirement planning. By knowing how much you need to withdraw, when the deadlines are, and how taxes apply, you can make smarter decisions to protect your savings and avoid unnecessary penalties.
