Estimating

What is equipment cost in construction?

Equipment cost is the full cost of the machines a job uses: rental bills for rented gear, and ownership plus operating cost for equipment the contractor owns.

Equipment cost is one of the four main direct cost types, next to labor, material, and subcontracts. For rented equipment it is easy: the rental invoice, delivery, fuel, and damage waiver. For owned equipment it is harder, because the machine has no invoice. The contractor has to set an internal hourly or daily rate that recovers what it costs to own and run the machine, then charge each job for the hours used.

What goes into an owned equipment rate

  • Ownership cost: depreciation (purchase price less expected resale, spread over its useful life), financing interest, insurance, property tax, and registration.
  • Operating cost: fuel, oil, filters, tires or undercarriage wear, and routine repairs.
  • Major repairs and overhaul: set aside per hour so the engine rebuild in year five is already paid for.
  • Not included: the operator's wages. Those go on the labor line, with burden.

How equipment cost works on a real job

Say a site contractor owns a mid-size excavator. The numbers below are illustrative; use your own purchase price, hours, and repair history.

Example: building an hourly rate for an owned excavator
Cost itemAnnual amount
Depreciation ($240,000 purchase, $90,000 resale, 6 years)$25,000
Interest on equipment loan$9,000
Insurance and tax$5,500
Fuel and fluids$22,000
Maintenance and repairs$14,500
Total annual cost$76,000
Expected billable hours per year1,200
Internal rate per hourabout $63

On a $185,000 storm drain job the excavator works 160 hours. The job is charged about $10,100 in equipment cost (160 hours times $63). If the estimate only carried fuel, the job would look $7,000 or so better than it really is, and the company would slowly bleed the cost of owning the machine.

For rented equipment, the estimate has to cover the full rental cycle, not just the days the machine works. A lift needed for 9 working days that sits on site over two weekends is often cheapest as a two-week rental. Add delivery and pickup charges, which can be a large share of a short rental.

Common mistakes

  1. Using the utilization you hope for. If the machine actually works 800 hours a year, a rate built on 1,200 under-recovers by a third.
  2. Charging only fuel to jobs and leaving ownership cost in overhead, which hides which jobs actually need the equipment.
  3. Letting rentals run. Off-rent calls that come a week late are pure waste. An equipment log helps.
  4. Using a published equipment rental rate schedule on a change order without checking what the contract allows.

Frequently asked questions

Should owned equipment be charged to jobs?

Yes. Charging an internal rate shows true job cost and recovers the cost of ownership in bids. Leaving it in overhead makes heavy-equipment jobs look better than they are.

Is the operator part of equipment cost?

Usually not. Most contractors put operator wages and burden on the labor line and keep equipment cost for the machine itself.

When is renting cheaper than owning?

When a machine would sit idle much of the year. Low utilization drives the owned hourly rate up, while a rental is paid only when needed.

What is standby time?

Time a machine is on site but not working, often because of a delay. Contracts may pay standby at a reduced rate on changes or delay claims, so record it in the daily log.
