401(k) plans by state
53
US states have at least 10 of the 57,824 large 401(k) plans 401(k) Monitor reads 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. Each count below reads all 57,824 large plans in the form-year-2024 DOL EFAST2 bulk data, so it is every plan of that size filed from that state, whether or not that plan has a page here. A plan with fewer than 100 participants files a shorter form and is not in this data at all.

States with too few plans for a page
These states and territories filed fewer than 10 large plans in this data. They get a page when a future DOL file carries enough of them; 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.
