Freight Load Contribution & Margin Calculator
Estimate load contribution, revenue per total mile, and hourly return after fuel, tolls, maintenance, and dispatch fees before accepting a load.
Spot load contribution & margin analyzer
Estimated load contribution
Fixed example assumptions: 6.4 mpg, 8% dispatch fee and $0.18 maintenance reserve per total mile. Excludes driver compensation, insurance, truck payments and other fixed overhead. Subtract those costs before treating this estimate as net profit.
Mathematical formula & methodology
Assumptions and limits
- Fixed example assumptions: 6.4 miles per gallon, 8% dispatch fee and $0.18 maintenance reserve per total mile.
- Change the displayed trip inputs to explore scenarios. Fixed assumptions remain unchanged in this calculator.
- Contribution excludes driver compensation, insurance, equipment payments and other fixed overhead. It is not net profit.
How to use this calculator
- Input the total broker rate confirmation offer.
- Enter the loaded billable miles and the unavoidable empty deadhead miles required to reposition to the pickup shipper.
- Enter estimated tolls and scale tickets for the intended route. Other charges, including washouts or permits, need to be accounted for separately.
- Input total elapsed transit hours including estimated dock loading and unloading delays.
- Examine estimated load contribution, revenue per total mile, fuel expense, and contribution per hour. Driver compensation and fixed truck costs are not included, so subtract them before treating this as net profit.
Operating context & strategy
Loaded-mile rates can hide repositioning costs. In an illustrative example, $1,050 over 300 loaded miles is $3.50 per loaded mile; add 200 empty miles and the same revenue is $2.10 per total mile. Whether that works depends on the carrier’s actual costs and alternatives.
Professional dispatchers evaluate loads using Total Miles Arithmetic: dividing gross revenue by (Loaded Miles + Deadhead Miles) and deducting fuel, tolls, maintenance wear, and dispatch fees. This estimate is load contribution, not fully loaded net profit: compare it with the carrier's cost-per-mile baseline and separately account for driver compensation, insurance, equipment financing, and other fixed overhead before accepting a load.
Elapsed trip time matters alongside miles. Compare feasible appointments, expected waiting, driver availability and reload options. Contribution per hour uses the elapsed hours you enter; it is not driver pay or proof that a reload will be available. Use a delay scenario when the dock or delivery window is uncertain.
Frequently asked questions
How should dispatchers evaluate deadhead miles against loaded rates?
Always calculate Revenue Per Total Mile: Gross Pay ÷ (Loaded Miles + Empty Deadhead Miles). If total revenue per mile falls below your carrier's break-even operating cost, the load should be negotiated higher or rejected in favor of closer freight.
How do highway tolls affect regional load profitability?
Use a current route-specific toll estimate for the actual vehicle, axle count, payment method and crossings. A different route may change fuel, time and restrictions as well as tolls. Include the trade-off in your planning rather than assuming a toll-free alternative is feasible.
What is an acceptable net profit margin for an independent motor carrier?
This calculator does not estimate fully loaded net profit or set a target margin. Its contribution figure excludes driver compensation and fixed overhead. Subtract all omitted costs and use your own operating goals before deciding whether a load is financially suitable.
