Contractor Equipment Hourly Cost Calculator
Calculate the true hourly cost to own and operate a piece of construction equipment — the basis for equipment line items in bids. Enter purchase price, useful life, salvage value, annual maintenance, insurance, and fuel costs to compute the true hourly cost and the minimum bid rate with a 20% margin. Equipment operated without capturing full ownership cost is equipment given to clients for free.

- Summary
- Equipment: $85,000.00 purchase price, 7-year useful life, $0.00 salvage. Annual depreciation: $12,142.86. Annual operating cost: $29,142.86 (depreciation $12,142.86 + maintenance $8,500.00 + insurance $2,500.00 + fuel $6,000.00). At 1000 hours/year: true hourly cost $29.14/hr. Minimum bid rate at 20% margin: $36.43/hr. CFMA guidance: equipment costs should be recovered in bids; operators who use equipment without capturing depreciation are effectively giving it away for free and will face a cash crisis at replacement.
How this calculator works
This calculator computes the true hourly cost to own and operate a piece of construction equipment. It adds up annual depreciation (straight-line), maintenance, insurance, and fuel, then divides by annual productive hours to produce a per-hour ownership cost. That rate is what the contractor must recover in bids for every hour the equipment works on a project.
Contractors who bid equipment at market rental rates without computing their own ownership cost often underprice when owned costs are high (low utilization, heavy equipment with expensive maintenance) or overprice when owned costs are low (fully depreciated equipment with low operating costs).
The four components of equipment cost
Annual depreciation: the most important and most commonly ignored cost. Depreciation represents the decline in the equipment's value as it is used. Straight-line depreciation: (purchase price − salvage value) / useful life years. A $85,000 excavator with zero salvage and 7-year life depreciates at $12,143/year — $12.14 per hour at 1,000 annual hours.
Annual maintenance: preventive maintenance, repairs, and parts. AGC's rule of thumb: annual maintenance runs 10-15% of purchase price in years 1-5. For heavy equipment operated in harsh conditions, budget toward the high end. Operators who under-budget maintenance face large unplanned repair costs that destroy project margins.
Annual insurance: inland marine (equipment floater) policy covering the equipment against damage, theft, and loss. For road-licensed vehicles, this is the commercial auto policy. Rates vary by equipment type, age, value, and operator experience rating.
Annual fuel: diesel or gas consumption at expected utilization hours. For excavators, wheel loaders, and similar equipment: estimate gallons per hour from the manufacturer spec × current diesel price × annual hours. Electric equipment uses kWh × local rate.
Utilization: the great multiplier of equipment cost
The utilization input (hours per year) is the most sensitive variable in the model. Doubling utilization halves the hourly cost, because all four cost components are fixed or semi-fixed per year.
| Annual hours | True hourly cost (example: $17K/year total cost) | |---|---| | 250 hours/year | $68.00/hour | | 500 hours/year | $34.00/hour | | 1,000 hours/year | $17.00/hour | | 1,500 hours/year | $11.33/hour | | 2,000 hours/year | $8.50/hour |
The practical implication: a contractor whose excavator sits idle for 6 months of the year is paying twice the hourly rate compared to a contractor with full utilization. Renting may be cheaper than owning for low-utilization equipment.
When to rent vs. own
Compare the computed true hourly cost from this calculator against local equipment rental rates for equivalent equipment:
- If your true hourly cost < rental rate: ownership is cheaper, assuming utilization is maintained.
- If your true hourly cost > rental rate: renting is cheaper, and you also eliminate the capital risk, the repair exposure, and the idle-cost problem.
The typical break-even utilization for general construction equipment (excavators, skid steers, lifts) is 400-700 hours per year — below that threshold, renting usually wins; above it, owning wins. Run this calculator at your actual expected utilization, then call your local equipment dealer or rental house for a current daily/weekly rate comparison.
Because most equipment cost is fixed — it accrues whether the machine is running or sitting in the yard. A $85,000 excavator with $17,000/year in total annual cost (depreciation + maintenance + insurance + fuel) costs $17/hour at 1,000 hours/year utilization and $34/hour at 500 hours/year utilization. Idle equipment doubles the hourly rate. This is why large equipment rental companies can undercut owned equipment on hourly rate for contractors with low utilization — the rental company achieves 2,000-3,000 hours/year of utilization across their fleet, while the small contractor's owned equipment sits idle for half the year. The buy-vs-rent decision should compare this calculated true hourly cost against the rental market rate for equivalent equipment.
