CONCRETE CONTRACTOR NET PROFIT MARGIN.

QUICK ANSWER

Healthy net profit margin for concrete contractors runs 5.5–6.5% at $1M–$10M in revenue, below the 12% CFOS target. The single biggest compressor is labor variance against the bid placement rate that goes untracked until closeout, well after the overrun could have been caught.

Concrete jobs are priced against an assumed placement rate, cubic yards per crew per day, but most contractors don't compare actual placement rate to that assumption until the job closes out. By then, whatever labor variance occurred is baked into the final number with no chance to correct course. That lag between when the variance happens and when it's discovered is what separates net margin from gross margin here.

Net Profit Margin Formula: Net Profit ÷ Total Revenue × 100. Net margin measures what's left after every cost is paid, including overhead; gross margin only measures job-level cost before overhead absorption.

DSO and Working Capital Ratio targets are flat across trades; margin and overhead targets are CFOS targets applied to concrete subcontractors. Benchmarks validated 2026-06-14.

WHY THE NUMBERS VARY

WHAT MOVES THIS NUMBER.

WHY NET PROFIT VARIES

Labor variance discovered at closeout instead of weekly is the primary compressor

Concrete crews are priced against a bid placement rate. Without weekly comparison of actual to bid rate, variance compounds silently across the job and only shows up in full at closeout, long after there was any opportunity to adjust crew size, sequencing, or billing.

WHAT DRIVES ABOVE-BENCHMARK PERFORMANCE

Above-benchmark concrete contractors track cost-to-complete by pour, weekly

Top performers compare actual placement rate to bid rate every week, by pour, not just at month-end. That visibility lets them catch and correct variance in week two or three instead of discovering it in the closeout report.

WHAT TO DO IF YOU ARE BELOW BENCHMARK

Check weekly placement-rate tracking, SOV billing structure, and change order discipline on weather holds first

If net margin is below benchmark, check whether placement rate is tracked weekly against the bid, whether the SOV bills mobilization and materials as their own line ahead of the placed-concrete milestone, and whether weather delays are documented as change orders.

COMMON QUESTIONS

FREQUENTLY ASKED.

A healthy net profit margin for concrete contractors is 5.5–6.5% at $1M–$10M in revenue, improving toward the 12% CFOS target with scale. Margins below that range at this size usually point to labor variance discovered too late to correct.
The gap is driven mostly by labor variance against the bid placement rate that isn't tracked weekly, plus pre-pour costs, formwork, rebar, pump trucks, that hit before any placed-concrete billing milestone is reached.
The three biggest compressors are labor variance discovered at closeout instead of weekly, pre-pour mobilization costs front-loaded before billing can start, and phase-stacking on multi-phase jobs that funds two phases of cost against one phase of collected revenue.
CFOS serves commercial concrete subcontractors subcontractors doing $1M–$12M. Monthly fees run $1,900 to $8,500 depending on revenue and which of the three service tiers fits your business (Core Financial, Executive Financial, or Strategic Financial). Onboarding takes 60 days.
