How many people have $1 million in their 401(k)?

Fidelity Investments counted 769,000 401(k) accounts with $1 million or more at the end of June 2026, a record. Fidelity’s plans cover 25.8 million 401(k) savers, so that’s about 3% of them.

The count covers only the plans Fidelity runs. Accounts at other providers aren’t in it, so the national total is higher.

The average 401(k) millionaire in Fidelity’s data is 58 and has been saving for about 25 years.

A 401(k) is one piece of net worth. Counting everything a household owns minus what it owes, about 21.5% of U.S. households are worth $1 million or more. See how many Americans are millionaires, or check your own rank with the net worth percentile calculator.
