Fleet Management • Operating Cost Per Mile

Fleet Total Cost of Ownership (TCO) & Operating Cost Per Mile

Calculated Output Metrics

Total Operating Cost Per Mile $2.05 / mile

Total Annual Cost Per Tractor $225,500.00 / yr

Fuel Cost Per Mile (6.5 MPG) $0.61 / mile

Fixed Equipment Overhead $0.39 / mile

Analytical Proof & Invariants

Machine Precision

Governing Mathematical Formula:

Cost Per Mile (CPM) = (Fixed Annual Overhead / Annual Miles) + Variable Operating Cost Per Mile

Step-by-Step Mathematical Derivation

Fuel Marginal Cost

Fuel Cost = $3.95 / 6.5 MPG = $0.608 per mile.

Maintenance & Tire Allowance

Standard Class 8 preventive maintenance, repairs, DEF fluid, and tires average $0.185 per mile.

Fixed Annual Overhead Conversion

Fixed Costs = (Lease $2,400 × 12 = $28,800) + Insurance $14,500 = $43,300/year. Overhead per mile = $43,300 / 110,000 miles = $0.394/mile.

Total Cost of Ownership

CPM = Fuel ($0.608) + Driver ($0.72) + Maint ($0.185) + Overhead ($0.394) = $1.907/mile ($209,770/year).

Frequently Asked Questions

What is the average cost to operate a commercial semi-truck per mile? +

According to the American Transportation Research Institute (ATRI), the average marginal cost of operating a Class 8 truck is $2.00 to $2.25 per mile, driven primarily by fuel (30%) and driver wages (35%).

How can fleet managers lower their cost per mile? +

Implement 65 mph speed limiters (improves fuel economy by 1 MPG), install aerodynamic trailer skirts and tire pressure monitoring systems, and negotiate bulk fuel network discounts.
