How Much to Charge for Excavation — Your Machine Rate, Built Honestly
The hourly rate on your card is carrying more than your time — it's carrying the iron. Excavation contractors who price from the going rate instead of their machine math are usually converting equipment equity into customer discounts. Here's the build.
The machine-rate calculation (mini-ex example)
- Ownership: $700/mo payment + $150 insurance ≈ $10,200/yr.
- Operating: fuel ~$12/hr, tracks/teeth/maintenance reserve ~$8/hr.
- Utilization honesty: 600 billable meter-hours a year (not the 2,000 you imagined).
- Machine cost/hr: 10,200 ÷ 600 + 20 = $37/hr before anyone sits in it.
- Operator loaded: $55/hr. Overhead share: $18/hr. Cost: $110/hr.
- At 35% margin: ÷ 0.65 ≈ $169/hr quoted. The bigger iron runs the same math with bigger numbers.
Pricing a job from the rate
Job = mobilization + (machine hours × rate) + trucking cycle + materials + restoration. Example: French-drain dig, 80 lf — float 45 min each way ($254), 5 machine hours ($845), stone 12 tons delivered ($540), pipe and fabric ($260), restoration hour ($169) ≈ $2,070 quoted. Every line defensible, every line reusable on the next drain.
The two leaks to plug
Free mobilization — the float is real hours on real diesel; line it. Optimistic utilization — dividing ownership across hours you don't actually bill makes every job quietly subsidize the machine. Count last year's meter hours and believe them.
