Owner-Operator Cost Per Mile Calculator

There's no single honest answer here — averages mislead more than they help, because your fixed costs and your miles per month are what set your number, not an industry-wide figure. The American Transportation Research Institute (ATRI) publishes the industry's standard annual operational-cost benchmark report, but the only cost per mile that matters for your rate decisions is the one you calculate from your own truck above.

Fixed costs — your truck payment, insurance, permits — hit every month whether you drive one mile or ten thousand. A parked truck still burns fixed costs. Variable costs only show up when the wheels turn. Splitting them matters because the more miles you run, the thinner your fixed costs spread per mile, which is why utilization drives your cost per mile as much as your rate does.

Use your real fleet average, calculated from your own fuel receipts and odometer readings — not the number on a spec sheet or a dealer's quote. A loaded Class 8 truck typically runs 6-7 MPG in real-world conditions, but terrain, load weight, idling habits, and truck age all move that number. Your receipts are always more accurate than a brochure.

Your all-in cost per mile is the floor under every rate you accept — quote below it and you're paying to haul the load. Use the break-even rate calculator to adjust that floor for deadhead miles, and the load profit calculator to test whether a specific load actually clears your number.
