EXCAVATION CONTRACTOR NET PROFIT MARGIN.
Excavation contractors at $1M–$5M revenue typically net 5.5–7.5% after overhead. At $5M–$10M, the target improves to 7.5–9.5% as overhead spreads over more revenue. Below 5% consistently means one of three things: equipment costs not fully allocated to jobs, overhead rate understated in bids, or labor overruns on production-rate-sensitive phases like rock, wet conditions, or tight urban sites.
Excavation is one of the most equipment-intensive trades in commercial construction. That equipment intensity creates margin pressure that most excavation contractors manage poorly — either by undercharging for owned equipment or by renting on jobs where owned machines should be deployed. This page covers net profit benchmarks by revenue band, the specific margin leaks unique to excavation, and how to close the gap.
NET PROFIT BY REVENUE BAND — EXCAVATION CONTRACTORS.
These are net profit ranges after overhead and owner salary. Gross margin for excavation typically runs 21–25%. If your gross margin is in range but net profit is low, the problem is overhead — the rate is too high or it is not being recovered in bids. If gross margin is also low, the problem starts in the estimate.
Context matters: These ranges assume the owner is paying themselves a market-rate salary through overhead — typically $120K–$180K at $3M–$8M revenue. If owner compensation is being drawn from profit instead of overhead, the net profit number is inflated and not comparable to benchmark.
THE THREE SPECIFIC PROBLEMS IN THIS TRADE.
Equipment Cost Not Allocated to Jobs Correctly
The most common margin leak in excavation. Owned excavators, dozers, scrapers, and haul trucks are deployed on projects but charged at an all-in daily rate that does not cover true ownership cost — replacement reserve, insurance, maintenance at real utilization, and idle days. A Cat 336 excavator that costs $1,100/day to own and operate getting billed at $800/day loses $300 every day it is on site. On a 45-day sitework project, that is $13,500 in unrecovered equipment cost — per machine.
Production Rate Variance on Difficult Ground Conditions
Excavation production rates vary dramatically with ground conditions — loose soil, rock, high water table, urban site constraints. Bids built on best-case production assumptions get beaten by average-case reality. If you estimate 200 CY/hour on common fill and hit rock at 3 feet, you are running at 40 CY/hour for days without a change order. Tracking production rate by phase and ground condition type across closed jobs is the only way to build estimates that hold up.
Haul and Disposal Costs Estimated at Optimistic Distance and Rate
Haul costs — trucking material on and off site — are notoriously easy to underestimate. Dump site distance changes, rates increase mid-project, disposal fees for contaminated material hit without warning. Building in 10–15% contingency on haul costs and tracking haul actuals by load is the fix. Haul should be its own job cost code, not bundled into general civil labor.
