Cost Per Mile Calculator

The Cost Per Mile Calculator computes what it costs to run a truck for one mile: fixed costs (truck payment, insurance, permits) spread over monthly miles, plus variable costs per mile (fuel from price and MPG, maintenance, driver pay) — giving the total cost per mile and the break-even freight rate a load must beat.

Formula

Fixed $/mile = Monthly Fixed Costs ÷ Monthly Miles · Fuel $/mile = Fuel Price ÷ MPG · Total $/mile = Fixed + Fuel + Maintenance + Driver Pay

Fixed costs accrue whether the truck moves or not — the payment, insurance, permits, and parking are the same at 5,000 or 12,000 miles a month, which is why cost per mile falls as utilization rises. Variable costs scale with distance: fuel per mile is simply the price per gallon divided by the truck's miles per gallon. The total is the floor for rate decisions: any load paying less than your all-in cost per mile (including deadhead miles to reach it) loses money.

Variable Definitions

Fixed

Monthly Fixed Costs

Truck payment, insurance, permits/plates, parking, and other costs that don't vary with miles.

Miles

Monthly Miles

All miles run in a month, loaded and empty.

Fuel ÷ MPG

Fuel Cost per Mile

Diesel price per gallon divided by the truck's average MPG.

Maint

Maintenance per Mile

Tires, preventive maintenance, and repairs averaged per mile — commonly $0.15–0.25.

Driver

Driver Pay per Mile

Driver compensation per mile, or salary converted to a per-mile figure.

Example Calculation

Scenario: An owner-operator runs 10,000 miles/month: - Fixed: truck payment $2,400 + insurance $1,100 + permits/other $400 = $3,900 - Diesel $4.10/gal, truck averages 6.8 MPG - Maintenance $0.19/mile · Driver (own) pay $0.65/mile Calculation: Fixed per mile = $3,900 ÷ 10,000 = $0.390 Fuel per mile = $4.10 ÷ 6.8 = $0.603 Variable per mile = $0.603 + $0.19 + $0.65 = $1.443 Total cost per mile = $1.833 Break-even rate = $1.83/mile; at +15% margin, target ≥ $2.11/mile A load offered at $1.70/mile is $0.13/mile underwater before deadhead — decline or negotiate.

How to Interpret Your Result

• Know this number before negotiating — brokers do. Loads below your all-in cost per mile only make sense to reposition the truck strategically. • Remember deadhead: if a 500-mile load needs 100 empty miles, spread the revenue over 600 miles when comparing to your cost. • Fixed cost per mile is your utilization lever: the same truck at 8,000 vs 11,000 miles/month can differ by $0.15+/mile in fixed burden. • Recalculate when diesel moves — a $0.50/gal swing at 6.8 MPG changes your cost by about $0.07/mile.
