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.

Estimated Load Contribution
Excludes driver compensation, insurance, truck payments, and other fixed overhead. Subtract those costs before treating this estimate as net profit.
Mathematical formula & methodology
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.
- Factor in estimated highway toll road expenses (such as the PA Turnpike, Ohio Turnpike, or NYC bridge crossings) and required trailer washouts.
- 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
Evaluating a freight load solely on the quoted rate per loaded mile is the most common dispatching mistake in trucking. A load paying $3.50 per loaded mile for 300 miles ($1,050 gross) that requires 200 miles of deadhead to pick up is actually a 500-mile trip paying only $2.10 per total mile — often below break-even operating costs.
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.
Trip duration and dock turnaround speed are equally decisive. A 500-mile run that unloads in forty-five minutes enables the driver to reload and run another load the next morning, whereas a load delivering to a congested grocery distribution center with six-hour dock detention destroys weekly asset productivity regardless of the initial rate per mile.
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?
Tolls through corridors like the Pennsylvania Turnpike, New York Thruway, or George Washington Bridge can exceed $150 to $300 for a five-axle commercial truck. Dispatchers must negotiate toll surcharges or route trucks through toll-free alternatives.
What is an acceptable net profit margin for an independent motor carrier?
Healthy independent carriers target a net operating profit margin between 15% and 25% after fuel, driver compensation, maintenance reserve, insurance, and equipment financing are fully deducted.
