Oil, gas and mining 401(k) plans
The median 401(k) plan in oil, gas and mining paid $124.28 per participant per year in plan-paid administrative fees, computed from 618 of the 653 oil, gas and mining plans on file, form year 2024.
Computed from DOL EFAST2 Form 5500 bulk data, not surveys. All 57,824 large plans in the form-year-2024 data are read here, so the 653 plans in this industry are every plan of that size filed under its business codes. The median is taken over the 618 of them whose filing reports a plan-paid administrative cost, because a filing that reports none has no cost to rank. It still does not describe the whole industry: a plan with fewer than 100 participants files a shorter form and is not in this data at all.

Median plan-paid administrative cost per participant per year among 618 oil, gas and mining plans with usable fee data, form year 2024.

Which employers count as oil, gas and mining here?
Oil and gas extraction, mining and support activities (codes 211110 to 213115) plus petroleum refining (324110 to 324199), grouped together so integrated oil companies sit with extraction. Sponsors here include ConocoPhillips, Exxon Mobil and Shell.
The code is the IRS principal business activity code the sponsor itself puts on Form 5500, line 2d. Medians count only plans whose Schedule H shows a positive plan-paid administrative expense (618 of 653 plans here). Plan-paid expenses exclude fund expense ratios and employer-paid bills, so every figure is a floor, not the all-in cost. Latest filing in this group received by the DOL July 20, 2026; source dataset last refreshed July 28, 2026. Full methodology
