Trucking Cost Per Mile Calculator
Enter your fixed costs, your miles and your fuel numbers, and this works out your cost per mile and the rate per loaded mile you need just to break even, with empty miles counted the way they actually bite. It is benchmarked against ATRI's published industry average, and unlike most cost-per-mile calculators it is not the front door to a software demo: no lead capture, no signup, just the arithmetic.
The formula, and which miles to divide by
Two divisions, two different questions. Dividing by all miles tells you what the truck costs to run, which is the number for comparing months and spotting creep. Dividing by loaded miles only tells you the rate you have to charge, because the empty legs cost nearly full price to run and earn exactly nothing, so the paying miles carry them. At a 16 percent deadhead share, every dollar of cost per mile becomes about $1.19 of required rate per loaded mile, and skipping that adjustment is the most common way an "I covered my costs" month quietly does not.
Worked example
$4,500 a month of fixed costs ($2,500 truck and trailer, $1,200 insurance, $800 everything else), 9,000 miles at 16% deadhead, 6.5 MPG at $5.90 diesel, 25 cents a mile of maintenance, no driver pay entered:
Fuel is 1,384.6 gallons, $8,169.23. Maintenance accrues $2,250. The month costs $14,919.23, which is $1.66 across all 9,000 miles but $1.97 per loaded mile, because only 7,560 of those miles paid. That $1.97 covers everything except the driver; pay yourself ATRI's industry-average $1.028 a mile and the rate that truly breaks even is about $3.20 a loaded mile.
Benchmarked against the industry's own ledger
ATRI's 2026 Operational Costs of Trucking report, the industry's standard reference, puts the 2025 average at a record $2.336 per mile: $1.854 of non-fuel costs plus about 48 cents of fuel, with driver wages and benefits at $1.028, which is 44 percent of the whole figure. Two honest cautions before comparing your number to it. The average leans toward large fleets, whose insurance and equipment cost less per mile than an owner-operator's, so running above it does not mean you are doing something wrong. And if you left driver pay blank, remember ATRI's figure includes it; add their $1.028 to your answer before comparing, or enter your own pay above.
If your break-even is above the board, the math is not the problem
ATRI reports truckload operating margins below 1 percent in 2025, the third year of the freight recession, with flatbed carriers averaging an operating loss. So a break-even rate that sits above the loads on offer is not a broken calculator; it is a precise measurement of a brutal market. What the number is actually for: knowing which loads to decline, seeing exactly how far a rate is from covering you, and watching the two levers that genuinely move it. More loaded miles dilute the fixed costs, and less deadhead raises the share of miles that pay; the result above prices both for your own numbers.
The costs that hide between the big lines
Fuel and the truck payment announce themselves. The lines that sink months quietly are maintenance, which accrues per mile even when nothing breaks (the industry average is around 25 cents, and it rose 8.6 percent in 2025), tolls, up 13.2 percent, the fastest-rising line in the report, and insurance, which has climbed for years and lands whether you drove or not. If your cost per mile looks better than the example above, check whether it is genuinely better or whether a future repair bill is riding along uncounted.

Frequently asked questions
What is the average trucking cost per mile in 2026?
ATRI's 2026 Operational Costs of Trucking report puts the 2025 industry average at $2.336 per mile, a record, of which $1.028 is driver wages and benefits and about 48 cents is fuel. That average leans toward larger fleets with cheaper insurance and equipment; a single owner-operator with a truck payment usually runs higher on everything except the driver line, which is your own income rather than a cost.
How do I calculate my cost per mile?
Add a month of fixed costs (truck payment, insurance, permits, parking, software), a month of variable costs (fuel from your MPG and the diesel price, plus maintenance and tires per mile), and divide by the miles you ran that month. The subtlety is which miles: dividing by all miles tells you what the truck costs, but dividing by loaded miles only tells you the rate you have to charge, because nobody pays for the empty legs.
Why does deadhead change my break-even rate so much?
Because the empty miles cost nearly as much to run and earn exactly nothing, so the loaded miles have to carry them. At the roughly 16 percent non-revenue mileage ATRI has reported, every dollar of per-mile cost becomes about $1.19 of required rate per loaded mile. Cutting deadhead from 16 to 10 percent is worth more than most fuel discounts.
What should I count as fixed versus variable costs?
Fixed costs arrive whether the truck moves or not: the truck and trailer payments, insurance, plates and permits, parking, ELD and software subscriptions. Variable costs scale with miles: fuel, maintenance, tires, tolls. The split matters because more miles dilute the fixed costs; the same truck costs less per mile in a busy month, which this calculator shows you directly.
Is my number supposed to be higher than the spot rate?
In the 2026 freight market, it might genuinely be. ATRI reports truckload operating margins below 1 percent in 2025, the third year of the freight recession, so a break-even rate that sits above the loads on the board is not a broken calculator, it is the market being brutal. The honest uses of this number are picking which loads not to take, and knowing exactly how far a rate is from covering you.
Where does my own pay go in this calculation?
Your choice, and the page handles both. Enter a driver pay per mile and it is treated as a cost, the way a fleet accounts for it. Leave it blank and the break-even rate is the floor that covers everything except you, so everything above that rate is your income. For scale, ATRI's industry average driver compensation is $1.028 per mile in wages and benefits.
What does maintenance really cost per mile?
ATRI-era figures put combined repair, maintenance and tires around 25 cents a mile as an industry average, and it was one of the fastest-rising lines in 2025, up 8.6 percent. Older trucks run higher and new ones lower, but the mistake that hurts is counting zero in the good months: the transmission bill was accruing per mile all along.
Why does this calculator not ask for my email?
Because it is a calculator, not a sales funnel. Most cost-per-mile tools online belong to factoring companies, load boards or fleet software vendors, and the arithmetic is the bait.
