Plans whose sponsor entered this principal business activity code on Form 5500.
Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances. The business code is chosen by the filer from the list in the Form 5500 instructions.
51 retirement plans in automotive mechanical, & electrical repair & maintenance with 100 or more participants filed Form 5500 for plan year 2024 (49 defined contribution, 2 defined benefit). All Form 5500 pension filers in the group reported 77,432 participant records and $4.06B in net assets.
The median defined contribution plan held $21,453 per participant, well below the national median of $53,031, and its employer put in $1,265 per active participant (national: $2,174). Among plans reporting Schedule C compensation the median was $103 per participant against $123 nationally.
Employers contributed $84.1M and participants $108M during the year, and the plans paid out $360M in benefits.
In 2009 the same group numbered 53 plans with $2.12B; by 2024 it was 51 plans (down 4%) and $4.06B (up 91%). From plan year 2023 the 100-participant line counts participants with account balances, which moved many plans to the short form.

Questions and answers
How many retirement plans are there in automotive mechanical, & electrical repair & maintenance?
51 plans with 100 or more participants filed Form 5500 for plan year 2024, out of 366 pension plans on the full form. Smaller plans file Form 5500-SF and are counted separately where shown.

The median defined contribution plan reported $21,453 in net assets per participant (middle half of plans: $12,356 to $37,554); nationally it was $53,031. This is a plan-level average that includes former employees, not a typical person's balance.
What do employers contribute in automotive mechanical, & electrical repair & maintenance?
The median defined contribution plan received $1,265 in employer contributions per active participant, against $2,174 nationally. Plans with no employer contribution are included at zero.
What are average 401(k) fees in automotive mechanical, & electrical repair & maintenance?
Among defined contribution plans that report any Schedule C compensation, the median was $103 per participant and 0.51% of net assets (nationally $123 and 0.26%). Schedule C leaves out fund expense ratios and fees the employer pays, so it understates total cost.
