Sitework contractors average 5.5% net profit margin at $1M–$5M, rising to 7.5% at $10M–$25M and 11.5% at $100M–$500M. The gap between average and top performers comes down to three things: self-perform percentage, whether environmental compliance overhead is priced into bids, and how consistently change orders get documented and billed.
Net profit is what's left after every dollar goes out the door — direct costs, field labor, materials, overhead, G&A, all of it. These are the industry averages for well-managed sitework operations at each revenue level. If you're below your band, the problem is almost always self-perform mix, environmental overhead recovery, or change order capture — not field performance.
How to calculate your net profit margin: Net profit after all expenses — including owner salary at market rate, not as a distribution — divided by total revenue for the trailing 12 months. Compare that number to the benchmark for your revenue band below.
Trade note — Sitework Contractors: Sitework net profit is directly tied to self-perform percentage. Contractors who self-perform 80%+ carry higher overhead — equipment, supervision — but typically generate 1–3% better net margin than subcontract-heavy operators. Self-perform retains the margin that would otherwise go to subs. If you're below benchmark, check your self-perform mix before you check anything else.
Sitework contractors below benchmark almost always have one of these three problems. None of them are field performance issues — they're financial structure and PM discipline issues. The good news is they're fixable.
SWPPP compliance, stormwater management, and environmental permit coordination create overhead that straight earthwork operations don't carry. Contractors who don't price this explicitly subsidize environmental compliance out of net margin on every site with environmental complexity. That's not a cost problem — it's a bidding problem.
When self-perform percentage drops — say from 70% to 50% — revenue may hold steady while overhead stays the same. The margin that used to come from self-performing that scope is gone, but the cost structure hasn't adjusted. Net margin compresses without anyone pulling a single bad job.
Additional clearing, changed grades, unexpected utilities — sitework scope changes are constant. Contractors who document and bill changes systematically show 2–4% better net margin than those who absorb it. That entire spread is driven by PM discipline on change order documentation, not field performance.
Net profit isn't something you discover at year end. It's something you manage monthly — by scope type, self-perform mix, and overhead allocation. Here's how SPM does it for sitework clients.
SPM sets up ControlQore to track net margin separately by sitework scope — clearing, grading, utilities, paving — for clients with multi-scope operations. Scope-level margin analysis reveals which parts of the business are generating returns and which are subsidizing the others. That visibility changes how bids get built.
When Executive clients are evaluating changes to their self-perform vs. subcontract mix, SPM models the net margin impact before the decision is made — showing whether the margin improvement from the changed scope mix justifies any overhead adjustment required. The model runs against actual job cost data in ControlQore.
SWPPP documentation, environmental coordination, and compliance reporting costs are tracked as a dedicated overhead category for sitework clients. This visibility surfaces the true cost of maintaining compliance capability — and supports accurate bid pricing on environmentally complex sites so the cost stops being absorbed from net margin.
Both tiers include ControlQore setup and full-service bookkeeping. Executive Financial adds the monthly CFO advisory layer — strategic meetings, WIP reporting, and direct access to Josh. No payroll. No scope gaps. Fully operational in 60 days.
Sitework contractors in the $1M–$5M range average 5.5% net profit margin. At $5M–$10M the benchmark is 6.5%, and at $10M–$25M it reaches 7.5%. Self-perform percentage, environmental compliance overhead recovery, and change order capture rate are the three biggest variables separating top performers from average at every revenue level.
Gross margin is revenue minus direct job costs — field labor, materials, subcontractors, and job equipment. Net profit margin is what's left after overhead is also deducted. Gross margin tells you if your jobs are priced and executed correctly. Net profit margin tells you if the whole business is generating a return. You need both numbers to run a construction company.
SPM's direct engagement covers $1M–$12M in revenue. The benchmark data on this page covers the full revenue spectrum for reference. For contractors above $12M, SPM can make the right introduction to firms that specialize at larger scale.
The benchmarks assume owner compensation is included as an expense at a reasonable market rate for the owner's role — not as a distribution. An owner-operator who takes no salary and reports 15% net profit isn't outperforming the benchmark — they're just not paying themselves. Normalizing for owner compensation makes the comparison meaningful.
