Lumber & Other Construction Materials: retirement plans
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.
199 retirement plans in lumber & other construction materials with 100 or more participants filed Form 5500 for plan year 2024 (198 defined contribution, 1 defined benefit). All Form 5500 pension filers in the group reported 160,475 participant records and $9.54B in net assets.
The median defined contribution plan held $63,377 per participant, above the national median of $53,031, and its employer put in $1,868 per active participant (national: $2,174). Among plans reporting Schedule C compensation the median was $153 per participant against $123 nationally.
Employers contributed $226M and participants $513M during the year, and the plans paid out $994M in benefits.
In 2009 the same group numbered 251 plans with $3.35B; by 2024 it was 199 plans (down 21%) and $9.54B (up 185%). 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 lumber & other construction materials?
199 plans with 100 or more participants filed Form 5500 for plan year 2024, out of 302 pension plans on the full form. Smaller plans file Form 5500-SF and are counted separately where shown.
What is the typical 401(k) balance in lumber & other construction materials?
The median defined contribution plan reported $63,377 in net assets per participant (middle half of plans: $43,526 to $91,425); 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 lumber & other construction materials?
The median defined contribution plan received $1,868 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 lumber & other construction materials?
Among defined contribution plans that report any Schedule C compensation, the median was $153 per participant and 0.28% 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.
Where does this come from?
Form 5500 annual reports in the EBSA research files, with filings received through 24 Aug 2026. Medians are computed by this site across plans with 100 or more participants.
