Required Minimum Distribution Calculator

Avoid stiff penalties for taking out too little from tax-deferred retirement plans

AARP, Updated May, 2022

Required Minimum Distribution (RMD)

Use this calculator to determine your Required Minimum Distribution (RMD). The IRS requires that you withdraw at least a minimum amount - known as a Required Minimum Distribution - from some types of retirement accounts annually. The distributions are required to start when you turn age 72 (or 70 1/2 if you were born before 7/1/1949). This calculator has been updated for the 'SECURE Act of 2019 and CARES Act of 2020'.

What is a required minimum distribution (RMD), and why should I care about it?

An RMD is the smallest amount you must withdraw from your tax-deferred retirement accounts every year after a certain age. At some point in your life, you may have put money into tax-deferred retirement accounts, such as Individual Retirement Accounts (IRAs) and 401(k) workplace retirement accounts. The key words here are “tax-deferred.” You postponed taxes on your contributions and earnings; you didn’t eliminate them. Eventually, you must pay tax on your contributions and earnings. RMDs make sure that you do that.

When do I have to take RMDs?

If you were born after June 30, 1949, you must start taking RMDs by April 1 of the year after you turn 72. Let’s say you celebrated your 72nd birthday on July 4, 2021. You must take the RMD by April 1, 2022. You’ll have to take another RMD by Dec. 31, 2022 and by Dec. 31 each year after that.

If you were born before July 1, 1949, you had to start taking your RMDs by April 1 of the year after you hit age 70 ½ (that’s six months after your 70th birthday). The Coronavirus Aid, Relief, and Economic Security Act (CARES Act), enacted in March 2020, suspended all RMDs for 2020. If you would normally have taken an RMD on Dec. 31, 2020, you must have taken one by Dec. 31, 2021.

How much do I have to withdraw each year?

The amount changes each year, according to your age. Start by calculating how much you had in all your tax-deferred accounts as of December 31 of the previous year. Next, find your age on the IRS uniform lifetime table and the corresponding “distribution period.” The distribution period is an estimate of how many years you’ll be taking RMDs. If you’re 72, for example, the distribution period is 25.6 years, based on your life expectancy. Then divide your balance by the distribution period. Let’s say you have a combined $100,000 in your tax-deferred retirement accounts. $100,000 divided by 25.6 is $3,906.25, which is the amount you must withdraw. If you are in the 25 percent combined state and local tax bracket, you’ll owe $976.56 in taxes on your RMD.

You can take your RMD out of one account, or take bits from each one, so long as you withdraw the required minimum.

What type of retirement accounts require RMDs? 

  • Traditional IRAs
  • Simplified Employee Pension (SEP) IRAs
  • Savings Incentive Match Plan for Employees (SIMPLE) IRAs
  • 401(k)s
  • Nonprofit 403(b) plans
  • Government 457 plans
  • Profit-sharing plans, and
  • Other defined contribution plans

Roth IRAs are funded with after-tax contributions, and they don't require RMDs until after the owner dies. If you're still working and have a traditional 401(k) or other workplace defined contribution plan, you may be able to defer RMDs until April 1 of the year after you stop working.

What if I don’t take my RMD?

Don’t skip an RMD. If you do not take any distributions, or if the distributions are not large enough, you may have to pay a 50 percent excise tax on the amount not distributed as required, according to the IRS.
