Gross revenue is not the number that matters
A truck grossing $18,000 a month can be less profitable than one grossing $14,000. The difference is what it costs to produce each mile — and most owner operators have never sat down and calculated it properly. Start with the total cost of running the truck for a month, divided by the miles actually driven that month, including empty ones.
The fixed costs almost everyone forgets
Truck payment, trailer payment, insurance, permits, IFTA, ELD subscription, parking, accounting and your own health coverage do not stop when the truck sits. Add them up annually and divide by twelve. That is your monthly nut — the number you must clear before the first dollar of profit exists.
Variable costs, honestly measured
Fuel, tolls, maintenance reserve, tires, def, lumpers, scale tickets and repairs. The reserve is the one carriers skip: a tire and brake job you did not budget for is not an emergency, it is an expense you failed to amortize. Set aside a per-mile reserve for maintenance from every settlement.
Now run the load math
Take the rate, divide by total miles including deadhead, and subtract your cost per mile. If the number is thin, the load is thin — regardless of how good the rate per loaded mile looked on the board. Do this on ten loads and you will find that your best-paying lanes are not the ones you assumed.
What to do with the number
Once you know your cost per mile, you have a floor. Every negotiation starts from it. A dispatcher who does not know your cost per mile is negotiating without knowing what a bad load is — which is exactly why we build this number into the lane strategy on day one.
This is the thinking behind billing & invoicing, back office support and route planning — the same analysis, run for you every week instead of read about once.
It applies hardest to dry van freight and box truck freight, where the margin is thin enough that the arithmetic decides the week.
