IRA Withdrawal Calculator for Forecasting Future Required Withdrawals

IRA Withdrawal Calculator Sign

The IRA Withdrawal Calculator will calculate your current minimum required withdrawal and then forecast your future required withdrawals if you are an IRA owner age 70-1/2 or older.

Not only will the calculator tell you which Life Expectancy Table was used to calculate the results, but it will also display a year-by-year chart showing your forecasted future required withdrawals based on your expected IRA account earnings -- up to age 113!

Note that if you are age 70-1/2 or older, but would just like to calculate an estimate of the current year's required minimum distribution, see the IRA RMD Calculator.

Or, if you are younger than age 70-1/2 but would like to forecast the effect required withdrawals will have on your present or future retirement, please use the IRA Distribution Calculator instead.

If you're not sure what required IRA withdrawals are or when they are required, or if you want to know what the calculator bases its calculations on, be sure to visit the Learn tab for answers.

Important: Please keep in mind that the results of this calculator are merely estimates so you should not use them for calculating your actual required withdrawal amounts. Consult your plan administrator for the exact amount required.

Help and Tools


Minimum withdrawal basics and the RMD formula.

When Do Withdrawals Start?

Minimum withdrawal (distribution) requirements come into play when an owner of a qualified retirement plan reaches age 70-1/2, or when a beneficiary assumes or inherits an IRA from the deceased owner.

You can defer withdrawal for the first year of the distribution to the following year (for tax purposes), but you must withdraw it before April 1st. After that, you must make your withdrawals before December 31st. The penalty for insufficient distributions is 50% of the undistributed amount.

Minimum Distribution Formula

To calculate the amount of your required minimum withdrawal, you first need to look up your life expectancy factor in the IRS life expectancy tables.

Once you find your life expectancy factor, you then divide the year-end balance of your IRA by that factor. The result is the amount you are required to withdraw from your IRA by the end of the current year (or April 15th of the following year if this is your first year of making required withdrawals).

IRS Life Expectancy Tables

IRS Life Expectancy Tables are three tables provided by IRS Publication 590-B for determining minimum distribution requirements for qualified retirement plans. The three tables are Single, Joint Life and Last Survivor, and Uniform Lifetime.

How the IRA Withdrawal Calculator Works

The IRA Withdrawal Calculator is based on Table II (Joint Life and Last Survivor Expectancy) and Table III (Uniform Lifetime) Table from IRS Publication 590-B (2018) (opens new window).

If your spouse is the sole beneficiary and is more than ten years younger than you, you must use Table II. If you are unmarried or your spouse is not more than ten years younger than you, or your spouse is not your sole beneficiary, you must use Table III. In either case, the calculated results will indicate which table the calculator used in the displayed results.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
