Utility Contractor Financial Benchmarks
Utility contractors, water, sewer, storm drain, and site utilities work, should target 22 to 30% gross profit per project, 12% net profit, and 9 to 13% overhead, the same as any commercial subcontractor. The number that gets missed most is equipment cost basis: the true daily, weekly, and monthly cost of owned and rented equipment. A $7.1M turnkey utility contractor went from maxed lines of credit to $750,000 in new available capital in 90 days once equipment costs and billing were rebuilt correctly.
Utility work runs on equipment: trenchers, excavators, compaction equipment, trucks. Most utility subs price it with a rough all-in hourly rate that bundles the machine, the operator, and fuel into one number pulled from memory or last year's bid. That number is almost always wrong, and it's wrong in the direction that quietly erodes margin.
| METRIC | HEALTHY TARGET | WITHOUT REAL EQUIPMENT COSTING |
|---|---|---|
| Gross profit per project | 22–30% | Diluted by unbudgeted equipment idle time |
| Net profit | 12% | Can run negative during fast growth phases |
| Overhead | 9–13% | PM time and mobilization often go untracked |
| Cash reserve | $650K+ | Frequently near zero during growth |
Case: $7.1M Turnkey Utility Contractor
This civil and utility contractor grew from $500,000 in year one to $5M in year two, projecting $12M in year three. Growth that fast usually feels like winning. It nearly cost him the business. By the time we came in, he had maxed two lines of credit, an SBA loan, and a personal line of credit secured against his home.
We built a cash flow forecast, corrected the billing process, and put a real collections routine in place. In the first 30 days, $310,000 in overdue receivables hit the bank. Within 90 days, all debt was cleared and the business qualified for a new $750,000 loan on the strength of clean financials.
How To Actually Calculate Equipment Cost Basis
The true cost of a piece of equipment includes ownership duration, replacement cost, general maintenance over its life, insurance and registration, and major repairs spread across the ownership period, divided by realistic annual working days. That produces a daily, weekly, and monthly rate you can actually bid against, instead of a number that feels roughly right.
What's a healthy overhead percentage for a utility contractor?
Target 9 to 13% of revenue, though PM time and mobilization costs specific to utility work often go untracked and push real overhead higher without contractors realizing it.
How do you calculate true equipment cost basis for utility work?
Combine ownership duration, replacement cost, maintenance, insurance, and major repairs, divided across realistic annual working days, to get a real daily, weekly, and monthly rate rather than a guessed hourly number.
Why does fast growth create cash problems for utility contractors?
Spending on labor, equipment, and materials happens immediately, while collections lag 30 to 45 days plus retention. Fast revenue growth without a cash flow forecast can outrun the business's ability to collect.
How fast can a utility contractor recover from maxed credit lines?
One turnkey utility contractor cleared two lines of credit and an SBA loan in 90 days and was approved for $750,000 in new capital, once billing and collections were rebuilt and receivables were collected systematically.
