Every dollar an owner-operator spends before payday comes out of the same pocket. There's no payroll department splitting off insurance, no fleet office negotiating fuel contracts.
Fuel, the truck itself, maintenance, insurance, permits, and taxes all draw down the same account before you see a cent of profit. Knowing where that money really goes is the difference between a business and a truck that happens to move freight.
Fuel is usually the biggest swing factor
Industry-wide, fuel ran $0.482 per mile in 2025, according to the American Transportation Research Institute's latest Operational Costs of Trucking update, barely changed from the year before. That stability didn't last. Diesel spiked past $5.50 a gallon last spring when the Strait of Hormuz disruption began.
Prices kept climbing from there, pushing past $6 a gallon during the third quarter, according to the Energy Information Administration. The disruption has dragged on for months, compounded by a Russian diesel export ban and refineries running near full capacity.
Fuel moves faster than almost any other line item, so it's worth checking against today's price before you set a rate. Pairing that with a fuel card is one of the few levers you actually control.
The truck itself is a fixed cost that never fully goes away
Combined truck and trailer costs averaged $0.404 per mile in 2025, whether that payment comes from a lease, a loan, or cash saved up front. The average truck on the road was 3.6 years old last year, with owners typically holding on to a tractor for about seven years and 633,000 miles before replacing it.
Once the note is paid off, the monthly bill disappears. The asset still needs to earn its keep in maintenance and downtime long after the payments stop.
Maintenance and tires rarely hold still
Repair and maintenance costs jumped 8.6 percent in 2025 to $0.215 per mile, reversing a rare dip the year before, as aging trucks and delayed replacements caught up with fleets across the industry. Tire costs climbed 6.4 percent to $0.050 per mile, driven in part by tariffs on imported rubber.
Skipping preventive service to save money in the short term tends to backfire. The average distance between breakdowns fell last year, meaning trucks are failing more often, not less. That pushes both repair bills and missed miles higher.
Insurance costs more than the premium
Truck insurance premiums rose 3.9 percent to $0.106 per mile in 2025, but the premium is only part of the real cost. Deductibles, self-insured retention, and litigation expenses add another layer on top.
That layer hits small and very large carriers hardest, for different reasons: small fleets pay more per mile for coverage itself, while large fleets absorb bigger out-of-pocket and legal costs when a claim goes to court.
Permits, tolls, and taxes are smaller but still add up
Permits and licensing averaged $0.008 per mile in 2025. Tolls climbed 13.2 percent to $0.043 per mile, the steepest jump of any line item that year.
None of that touches the biggest fixed obligation of all: self-employment tax, set by the IRS at 15.3 percent of net income, on top of whatever federal and state income tax is owed. A quarterly estimate, paid on time, keeps that bill from becoming a surprise every April.
Hidden costs to remember
Deadhead mileage, the miles you drive without a paid load, never shows up as its own line on an invoice, but it isn't free. ATRI's 2026 update put the industry's non-tank deadhead rate at 16.5 percent of all miles driven last year, and tank haulers ran empty on 44.3 percent of theirs.
Every one of those miles still burns fuel and adds wear without adding a dollar of revenue. It's the cost most drivers underestimate, because it never shows up as a bill, just as a lower number at the end of the week.
Know your number, then protect it
Fuel, the truck payment, maintenance and tires, insurance, permits, tolls, taxes, and the miles you drive without a paid load all add up to the same thing: what it actually costs you to run your truck. Add them up against your own mileage, line by line, and you get a number that matters more than any industry benchmark.
That number, not the one on the rate confirmation, is what tells you whether a load is worth taking.
Most owner-operators can tell you their rate. Fewer can tell you their number. The ones who can are usually the ones still running next year. Truckstop's Load Board helps you find loads that cover your cost per mile, and the Truckstop Fuel Card helps you cut fuel costs so you can keep more of what you earn. Start with Truckstop, and put that number to work before your next load.
