Job costing and finance

How to price equipment costs into a construction job

Price owned equipment with an hourly rate that covers both ownership cost (depreciation, financing, insurance, storage) and operating cost (fuel, maintenance, repairs, wear), then multiply by the hours the job needs. Price rented equipment at the full delivered cost, not just the rate on the quote.

To price equipment into a construction job, give every owned machine an hourly rate equal to its yearly ownership cost plus its operating cost, divided by the hours it actually works in a year. Multiply that rate by the hours the estimate needs, then add mobilization, demobilization, and the operator as separate lines. For rented equipment, use the full cost: rental rate, delivery and pickup, fuel, damage waiver, and any minimum charges. Either way, the equipment cost lands on the job as a direct cost, not buried in overhead.

Many small contractors charge nothing for equipment they own outright because "it's paid for." The machine is still wearing out, still insured, still parked somewhere. When it dies, the replacement has to come from job profits that never accounted for it.

What goes into an equipment rate

Federal cost rules for construction equipment are a useful checklist even on private work. FAR 31.105(d)(2) separates ownership and operating costs, lists operating allowances such as fuel, filters, oil, grease, servicing, repairs, maintenance, and tire wear, and notes that labor, mobilization, demobilization, overhead, and profit are generally not part of the equipment rate and need separate consideration. It also names the U.S. Army Corps of Engineers equipment schedule as an example of a predetermined rate schedule a contracting agency may specify.

How to build an hourly equipment rate

1. Estimate annual working hours honestly

Use hour meter readings and your equipment log, not the hours you wish the machine ran. Utilization is the biggest single driver of the rate. A machine that works half as many hours carries twice the ownership cost per hour.

2. Calculate yearly ownership cost

Depreciation is purchase price minus expected resale value, divided by years you plan to keep it. Add a cost of capital on the average investment (the interest you pay, or what the money would earn elsewhere), plus annual insurance, registration, and a share of yard or shop cost.

3. Calculate operating cost per hour

Fuel burn per hour times your fuel price, plus maintenance and repairs per hour from your service records, plus tire or track wear. If you have no history, start with the manufacturer's service intervals and parts prices and refine it after a season.

4. Add them and set the rate

Ownership per hour plus operating per hour is your cost rate. Some contractors also set a lower standby rate for days the machine sits on site but does not run, which covers ownership but not fuel or wear. FAR 31.105 uses a similar idea for suspended work on federal jobs, capping ownership allowances at a standby amount.

5. Charge it to jobs the same way you priced it

Post equipment hours to each job's equipment cost code at the internal rate, offsetting an equipment income or recovery account. At year end, compare what the rates recovered to what the fleet actually cost. If recovery runs short, the rates or the utilization assumption were wrong.

Worked example: a compact track loader

Say a sitework contractor owns a track loader. All figures are illustrative; plug in your own.

Example hourly rate at 1,000 hours a year
ItemAnnualPer hour
Depreciation ($68,000 cost, $20,000 resale, 5 years)$9,600$9.60
Cost of capital (7% on $44,000 average investment)$3,080$3.08
Insurance and registration$1,800$1.80
Yard and storage share$600$0.60
Fuel (2 gallons an hour at $4.00)$8.00
Maintenance and repairs$6.50
Tracks and wear parts$2.00
Total cost rate$31.58

A grading job needs about 120 machine hours, so equipment cost is roughly $3,790. Add two trailer hauls for mobilization and demobilization at, say, $350 each, and the operator at the burdened labor rate as its own line. Overhead and profit go on top of all of it.

Now say the loader only works 500 hours a year. Ownership cost per hour doubles from $15.08 to $30.16 and the total rate climbs to about $46.66. At that utilization, renting for the jobs that need it may cost less than owning. When to buy vs rent construction equipment walks through that decision.

Pricing rented equipment

Rental quotes look simple and rarely are. Price the equipment rental rate at the increment you will actually use (daily, weekly, or monthly), then add delivery and pickup, fuel or refueling charges, damage waiver or your own insurance, environmental or service fees on the quote, and a buffer if the schedule could slip into another rental period. Track it against the purchase order so off-rent calls happen on time. See how to manage equipment rental costs.

Where equipment rates show up after the bid

The rate is only useful if field hours get recorded against it. Have operators or foremen log machine hours by job and cost code on the daily report, the same way they log labor. Hour meter readings at the start and end of each week catch the gaps. When a machine moves between two jobs in one day, split the hours rather than charging the whole day to whichever job it ended on.

Review the rates once a year with actual fleet costs from the books. Fuel prices, insurance renewals, and a bad repair year can each move the operating side by a few dollars an hour. On change orders and T&M work, use the same internal rate plus markup so extra work recovers equipment the way base-bid work does. Keeping one rate sheet for estimating, job costing, and change orders avoids arguments later about which number was right.

Mistakes to avoid

  1. Charging nothing for paid-off equipment. It still costs money to insure, store, repair, and eventually replace.
  2. Using a rental company's rate for owned equipment. It includes their overhead and profit. Use your own cost and add your markup once.
  3. Leaving mobilization out. Two hauls on a small job can cost more than the machine hours.
  4. Rolling equipment into overhead. Then every job carries the excavator, including the interior finish jobs that never saw it.
  5. Never checking recovery. If the fleet cost $90,000 last year and jobs were charged $60,000, $30,000 of cost hid in overhead.

Frequently asked questions

Should equipment be a direct cost or overhead?

Equipment used on a job should be charged to that job as a direct cost at an hourly or daily rate. Only equipment that supports the whole company, like a shop forklift, belongs in overhead.

Is the operator included in the equipment rate?

Usually not. Most contractors price the operator as labor at a burdened rate on a separate line. FAR 31.105 also treats labor as separate from equipment ownership and operating costs.

What is a standby rate for equipment?

A standby rate is a reduced rate for days a machine is on site but idle. It typically covers ownership costs but not fuel, maintenance, or wear, since the machine is not running.

Can I use a published equipment rate schedule?

On some public contracts the agency specifies one. FAR 31.105 names the U.S. Army Corps of Engineers construction equipment schedule as an example. On private work, your own cost-based rate is usually more accurate for your fleet.
