401(k) plans by state
53
US states have at least 10 of the 57,824 published 401(k) plans on 401(k) Monitor headquartered there, led by California with 6,801 plans on file. Each state page ranks the largest plans and compares the state’s plan-paid fees with the national median of $122.17 per participant.
State means the sponsor’s address on the Form 5500, not where employees work. Our published set covers 57,824 of the 57,824 large plans in the form-year-2024 DOL EFAST2 bulk data, richest data first, so state counts grow as coverage grows.

Coming as coverage grows
These states and territories have published plans on file, but fewer than 10. They get a page once enough plans are published; the plans themselves are already searchable from the home page.

Where these numbers come from
Every large 401(k) plan files a Form 5500 with the Department of Labor. We group the published plans by the sponsor’s state, rank them by active participants, and take the median of plan-paid administrative cost per participant where the filing makes it computable. The “largest plan” column above is a different measure: Schedule H total assets at end of plan year. Full detail in the methodology.
