How to use this guide
Read the sections in order the first time, then use the headings as a working checklist. Keep one time period, vehicle or fleet definition, and set of units throughout the calculation. Replace examples with actual documents and note the source date when a rate or rule can change.
Save or download a calculator scenario only after reviewing every field. The site performs planning arithmetic; it does not validate the records, determine legal treatment, submit a form, or bind a carrier, customer, government agency, lender, or tax authority.
Start with complete revenue
Include linehaul and only the fuel surcharge or accessorial revenue reasonably expected under the rate confirmation. Separate reimbursements from true revenue where the distinction matters. Confirm loaded miles and realistic deadhead.
Do not count a backhaul that has not been booked as guaranteed revenue.
Allocate complete trip cost
Estimate fuel across all miles, maintenance and tire reserve, driver pay, tolls, permits, loading expenses, fixed-cost allocation, and other trip-specific costs. Time should include waiting and non-driving work relevant to the decision.
The load-profit calculator calls the result contribution profit because unentered business costs and taxes may remain.
Use scenarios and post-trip review
Run expected, downside, and upside cases for fuel, deadhead, waiting, and extra costs. Compare contribution profit with the target entered by the user rather than a hidden universal threshold.
After settlement, replace estimates with actual revenue, gallons, tolls, hours, and costs. The difference improves future bidding and identifies lanes that appear profitable only before reconciliation.
Verification and decision checklist
- Define the business question and time period before collecting inputs.
- Use primary records and current official sources where they apply.
- Keep paid miles, all miles, revenue, cash, deduction, tax effect, cost, and profit labels distinct.
- Run a conservative scenario when price, miles, utilization, delay, or tax treatment is uncertain.
- Compare the planning result with the controlling contract, settlement, filing instructions, or professional review.
Update the calculation when a route, quarter, rate, carrier policy, equipment decision, or source document changes. A saved estimate is a snapshot of assumptions, not a live guarantee.
