BREAKING EQUIPMENT COST OUT IN JOB COSTING.
Most subcontractors bill equipment as one all-in hourly rate that buries the machine, the operator, fuel, mobilization, and fees together. When the job goes over, you cannot tell which one moved. Breaking equipment into separate cost codes, machine, operator, fuel, and fees, is what lets you see where a job is actually bleeding.
A $7.1M civil contractor was running 34 pieces of equipment and 14 trucks on a single all-in hourly rate. A skid steer billed at $450 an hour looked fine until you ran the real numbers: $979 a day just to have it on site, $200 to mobilize, fuel at 8 gallons an hour, and an operator at $47 an hour fully burdened. On a two-hour task they billed two hours and lost money every time. Once equipment was broken into separate cost codes and a daily standby rate was charged, the picture changed and their balance sheet improved by $779,000. The money was always there. They just could not see it. This page shows how to break equipment cost out in job costing.
WHY THE ALL-IN RATE HIDES LOSSES.
When equipment, operator, fuel, mobilization, and fees are bundled into one hourly number, an overrun is invisible. Did you burn more fuel than planned? Was the machine on site longer than estimated? Did the operator switch to a twelve-hour day? You cannot tell, because it is all one figure.
The fix is to break them out. Equipment cost basis is the true daily, weekly, or monthly cost to own and run a specific machine, separate from the operator who runs it and the fuel it burns. Track each against the plan and an overrun points to its cause instead of hiding in an average.
SEPARATE WHAT MOVES SEPARATELY.
The cost to own the machine, billed by time on site.
Charge a daily, weekly, or monthly rate for the machine being on the job, separate from whether it is running. This covers ownership: replacement cost, maintenance, insurance, and registration spread across the days you actually work it. A machine on site for a day costs you a full day even if it runs two hours, so it should be billed for the day.
Tracked apart from the machine.
The operator is labor, not equipment. Keep them in separate cost codes so that when an operator switches tasks or a day runs long, the labor overrun shows up on its own line instead of muddying the equipment number. Track operator cost fully burdened, including taxes, workers comp, and benefits.
The variable lines that quietly add up.
Fuel is consumption and moves with hours run, so it belongs on its own line where you can compare it to estimate. Mobilization, staging, and permit fees are one-time costs per deployment. Separating them is how you catch a job where the machine sat idle burning standby cost while the SOV only paid for run time.
HOW RENTAL MATH SHOULD WORK.
When you bill equipment by the week or month, there are 13 months in a year, not 12. Four weeks equals one month, the way rental companies charge you, and the way you should charge for owned equipment. A five-week project is one month and one week.
Pricing your owned equipment the way a rental house prices its fleet does two things: it recovers the real carrying cost of the machine, and it tells you honestly when renting is cheaper than owning. A $7.1M civil contractor found they were renting machines on one job while an identical owned machine sat idle on another, paying twice for the same capability because no one could see where equipment needed to be.
BUILD THE EQUIPMENT COST BASIS.
Breaking equipment out is a one-time setup that pays back on every job after:
SEE THE MACHINE, SEE THE MONEY.
Equipment is the second-largest cost on most civil and sitework jobs, and the all-in rate is where its losses hide. Break it out and the overruns become visible while there is still time to act.
The Construction CFO builds equipment cost basis into job costing as part of CFOS for subcontractors doing $1M to $12M, the same setup that recovered $779,000 of buried value for one civil contractor.
