Excavation Contractor Net Profit Margin.
Excavation contractors net 5.5 percent at $1M to $5M, rising toward 7.5 percent by $10M to $25M as overhead spreads over more revenue. Gross margin runs 21 to 26 percent and overhead falls from 14 to 11 percent across those bands. Hitting the benchmark is a job-costing and equipment-cost question, not a volume question.
If you run an excavation business and want to know whether your profit is where it should be, this page gives the net profit, gross margin, and overhead benchmarks by revenue band, the equipment-cost trap that quietly drains margin, and the two systems that turn the benchmark into a floor.
5.5 To 7.5 Percent By Revenue Band.
Excavation contractors net 5.5 percent at $1M to $5M and climb toward 7.5 percent by $25M as overhead spreads over more revenue. That is the net profit benchmark, what is left after both direct job costs and overhead. Gross margin runs 21 to 26 percent across those bands, and overhead falls from 14 percent down to 11 as the business scales.
Net profit is the only number that proves the business works. You can run full crews and full equipment and still net nothing if the jobs are not costed and the overhead is not controlled. The benchmark below is the bar. Hitting it is a job-costing and overhead question, not a volume question.
| Excavation Revenue Band | Gross Margin | Overhead | Net Profit |
|---|---|---|---|
| $1M to $5M | 21% | 14% | 5.5% |
| $5M to $10M | 23% | 13% | 6.5% |
| $10M to $25M | 24% | 12% | 7.5% |
| $25M to $50M | 26% | 11% | 8.5% |
The CFOS target runs a step better than the industry average: gross margin plus 2 points, net profit plus 1.5, overhead minus 2. At $1M to $5M that turns a 5.5 percent benchmark into a 7 percent target.
Where Excavation Net Profit Leaks.
Excavation is equipment-heavy, and equipment is where the margin hides. Most subs bundle the machine, the operator, the fuel, and the mobilization into one all-in hourly rate. When it is all one number you cannot see whether you went over on fuel, ran the machine longer than estimated, or stretched a day into twelve hours. The job looks fine until the year does not.
A $7.1M civil and earthwork contractor with 34 machines and 14 trucks was estimating everything as one bundled rate. A skid steer billed at two hours of work sat on site all day at a real cost of $979, losing money every time. Once the equipment cost basis was broken out, machine by machine, with separate rates for the unit, fuel, and mobilization, the balance sheet was up $779K in three months. The money was always there. It was buried in a bundled rate.
Cost The Machines, Then The Jobs.
Net profit on excavation work follows from two systems. First, an equipment cost basis that prices every machine by the day, week, and month, separate from fuel and mobilization, so idle days and overruns show up. Second, job costing that mirrors the estimate so you know in real time whether a job is trending over or under, not three months after it closed.
With both in place the overhead number gets honest, the bids get built on real costs, and the 5.5 to 7.5 percent benchmark becomes a floor instead of a hope. The Construction CFO installs both as part of the engagement and runs the monthly cadence that keeps them accurate.
