At age 73, with a prior year-end balance of $500,000, your distribution period is 26.5. This requires a mandatory withdrawal of $20,000.00 for the current tax year. If your portfolio grows at an annual rate of 6.0%, the balance at age 100 is projected to be $258,506.47, with a cumulative total of $1,074,303.41 withdrawn in RMDs.

How to Calculate Your RMD

Each year, your RMD is calculated by dividing your account balance on December 31 of the prior year by your life expectancy factor from IRS Table III:

RMD = Account Balance (as of Dec 31) ÷ IRS Distribution Period

For example, if you are age 73 with a previous year-end balance of $500,000, your distribution period is 26.5. Your RMD is:
$500,000 ÷ 26.5 = $18,867.92 (which is roughly 3.77% of the total balance).

Frequently asked questions

At what age do Required Minimum Distributions (RMDs) start?

Under SECURE Act 2.0, RMDs start at age 73 for individuals born between 1951 and 1959. For individuals born in 1960 or later, RMDs start at age 75. Roth IRAs do not require lifetime distributions.

How is an RMD calculated?

Your RMD is calculated by taking your traditional IRA or 401(k) account balance on December 31 of the previous year and dividing it by the distribution period (life expectancy factor) matching your age in the IRS Uniform Lifetime Table (Table III).

What is the penalty for missing an RMD?

The penalty for failing to take an RMD is 25% of the amount that should have been withdrawn but wasn't. This penalty can be reduced to 10% if you correct the error and withdraw the missing amount within a timely correction window.
