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 PayFixed 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
Monthly Fixed Costs
Truck payment, insurance, permits/plates, parking, and other costs that don't vary with miles.
Monthly Miles
All miles run in a month, loaded and empty.
Fuel Cost per Mile
Diesel price per gallon divided by the truck's average MPG.
Maintenance per Mile
Tires, preventive maintenance, and repairs averaged per mile, commonly $0.15–0.25.
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.
