FLEET BURDEN

CONSTRUCTION FLEET BURDEN AND OVERHEAD THE TRUE COST OF COMPANY VEHICLES.

QUICK ANSWER

A contractor who answers the question what does your truck cost with the monthly payment is understating the real cost by a factor of 2 to 3x. Insurance, fuel, maintenance, registration, and depreciation are all fleet costs. Left out of the overhead rate they get paid out of project margin, and the bid never recovers them. Across a fleet of 8 vehicles that understatement runs $80,000 to $120,000 per year, absorbed from net profit on every project, year after year. The fix is a fleet cost inventory that calculates true annual ownership cost per vehicle and allocates it correctly, to overhead for non project vehicles and to direct job cost for project assigned equipment.

Two numbers go wrong at once when fleet is treated as one lump of overhead. Overhead comes out too high, because trucks assigned to a single project are sitting in it. Job level margin comes out too low, because those same trucks are never charged to the project they serve. Both errors compound, one at bid time and one at closeout. Contractors who build a true cost per day for field equipment and charge it to the project usually find their real overhead rate moves 2 to 4 points, and that the movement was cost they were already paying.

THE DEFINITION

WHAT IT MEANS.

Fleet burden is the true annual cost of a company truck or piece of equipment, not just the payment.

WHAT WE SEE IN THIS BUSINESS

WHY THE FLEET NUMBER IS WRONG.

01

The payment isn't the cost

A company truck with a $650 per month payment costs $7,800 per year in principal and interest. It also costs comprehensive insurance at $2,400 per year, registration and plates at $300 per year, fuel at $4,200 per year at average utilization, maintenance and tires at $1,800 per year, and depreciation at $6,500 per year on a $32,500 truck depreciating over 5 years. Total annual ownership cost is $23,000, or $1,917 per month, which is roughly 3x the payment most contractors quote when they're asked.

02

Every vehicle sits in overhead regardless of assignment

Company vehicles that go to specific projects belong in those projects as direct job expense. A superintendent truck that's 100 percent on one project belongs in that project's direct cost, while a shop truck used across all projects belongs in overhead. Treating all vehicles as overhead inflates the overhead rate and understates direct job cost at the same time, so both numbers are wrong in ways that compound at bid time and at closeout.

03

There's no cost per day for field equipment

Equipment deployed to specific projects needs a true cost per day: annual depreciation plus annual insurance plus annual maintenance plus annual fuel, divided by productive days per year. Without that charge rate, equipment cost stays in overhead and the project that used the machine never carries it. Job level margin on that project then reads better than the work really earned.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

One truck, the full cost stack

A $650 per month payment is $7,800 a year. Add insurance at $2,400, registration and plates at $300, fuel at $4,200, maintenance and tires at $1,800, and depreciation at $6,500 on a $32,500 truck over 5 years. Total annual ownership cost is $23,000, which is $1,917 per month against a $650 payment.

Eight vehicles, one year

When that difference exists across 8 company vehicles, the fleet burden in overhead is understated by $101,600 per year. That's cost the business is already paying and not recovering in any bid price. It comes out of net profit on every project until the overhead rate is corrected.

The bid rate correction

Most contractors who run this exercise for the first time find their real overhead rate increases by 2 to 4 points from underaccounted fleet burden. That increase is real cost that was being absorbed from project margin on every job. Correcting the rate at bid time recovers it going forward, without changing what the business costs to run.

HOW TO BUILD ACCURATE FLEET BURDEN

THREE STEPS TO THE REAL NUMBER.

Inventory every company vehicle and piece of equipment

Record the VIN or serial number, acquisition cost, current book value, monthly payment, insurance cost, annual maintenance budget, and primary assignment, whether project, overhead, or mixed. The inventory is the part most contractors have never built. It's the input to everything else on this list.

Calculate true annual ownership cost for each

Payment plus insurance plus registration plus fuel at average utilization plus maintenance. That total is the number that belongs in the overhead rate or in direct job cost, not the payment alone. Depreciation belongs in it too, because the truck is being consumed whether or not anybody books the entry.

Assign each item to overhead or direct based on actual usage

Project assigned equipment goes to direct job cost at the project charge rate, overhead assigned equipment goes to overhead, and mixed use equipment gets prorated. Then the overhead rate calculation gets updated with the corrected fleet figures. Both the overhead rate and the job level margin become usable at the same time.

Build the equipment charge rate for field equipment

For equipment deployed to projects, the cost per day is annual depreciation plus annual insurance plus annual maintenance plus annual fuel, divided by productive days per year. When the machine goes to a project, the charge rate goes with it as direct cost, and the equipment ownership cost sitting in overhead drops by the amount charged out. The result is job level margin that includes the real cost of the equipment that did the work.

COMMON QUESTIONS

FREQUENTLY ASKED.

Prorate it by estimated usage. If the superintendent truck is 70 percent on one project and 30 percent general, then 70 percent of the true annual cost goes to that project as direct job cost and 30 percent goes to overhead. Document the proration and apply it the same way every month, and where usage swings a lot by period, track mileage by project monthly and reallocate quarterly.
Depreciation on vehicles and equipment used on specific projects belongs in direct job cost through the equipment charge rate. Depreciation on overhead vehicles, meaning office vehicles, the owner vehicle, and yard equipment not deployed to projects, belongs in overhead. The question to ask is always whether the asset is generating project revenue or supporting the business, because project goes direct and business support goes to overhead.
Yes. The overhead rate calculation at engagement start includes a fleet inventory: true annual cost per vehicle and piece of equipment, the project or overhead assignment, and the resulting fleet burden in the overhead rate. Most clients find the fleet burden correction increases the overhead rate by 2 to 4 points and recovers $15,000 to $60,000 annually in overhead cost that wasn't being recovered before.
