401(k) balance by age

Arc does not publish a 401(k)-only balance by age. The Federal Reserve bulletin reports retirement accounts that combine IRAs, Keogh accounts, and employer plans. In 2022, 54.3% of families held one, with a conditional median of $86,900 and a conditional mean of $334,000. Those are not 401(k) balances.

No 401(k)-only series

The bulletin’s retirement-account figures include IRAs, Keogh accounts, and employer plans such as 401(k), 403(b), and thrift savings accounts. A 401(k)-only median by age is not in that table. These numbers are not relabeled as 401(k) balances.

What would still be required

A 401(k)-only table would name the plan type, say whether workers with a zero balance are included, and give a year. The bulletin’s definition is wider than that on purpose. Until a primary 401(k)-only series is added, this page shows the combined-account figures and says what they are.
