EXCAVATION CONTRACTOR NET PROFIT MARGIN.
Healthy net profit margin for excavation contractors runs 5.5–6.5% at $1M–$10M in revenue, against a 12% CFOS target. The single biggest compressor is blending structural and mass excavation rates together, which hides the fact that structural excavation costs significantly more per unit to perform.
Excavation contractors often price a job with one blended rate covering both mass excavation and structural excavation, even though the two use different equipment classes and carry very different production costs. That blending shows up as fine gross margin on the estimate, but net margin erodes as the actual cost mix skews toward the more expensive structural work. The fix isn't a better bid; it's separating the two cost structures so both get priced and tracked correctly.
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.

| METRIC | INDUSTRY LOW | SPM TARGET | STRONG | NOTES |
|---|---|---|---|---|
| Net Profit Margin | 5.5% | 12% | 11.5% | Primary bottom-line indicator; most compressed by unbilled cost categories. |
| Gross Margin | 21% | 22–30% | 30% | Job-level margin before overhead absorption. |
| Overhead Rate | 14% | 9–13% | 8% | Lower is better; scales down as revenue grows. |
| Days Sales Outstanding | 90 | 45 | 30 | Time from billing to cash in hand. |
| Working Capital Ratio | 1.0 | 1.5 | 2.0+ | Current assets to current liabilities. |

WHAT MOVES THIS NUMBER.
Blended excavation rates hide which type of work is actually costing more
Structural excavation, foundation work, requires tighter tolerances, more careful equipment operation, and often hand work at the edges, all of which cost more per cubic yard than open mass excavation. When both are priced under one blended rate, net margin absorbs the difference invisibly.
Above-benchmark excavation contractors separate structural and mass excavation cost codes
Top performers track cost per cubic yard separately for structural versus mass excavation and price accordingly, instead of relying on one blended historical rate. They also treat equipment standby during site access delays as its own billable event.
Check rate blending, standby billing, and backfill/compaction cost codes first
If net margin is below benchmark, check whether structural and mass excavation are tracked as separate cost codes, whether equipment standby during access delays is billed or absorbed, and whether backfill and compaction are broken out from the excavation rate or lumped in.
