The Record Cost Per Mile Is Not Fuel. It Is Everything Else

ATRI's highest cost per mile ever is not fuel. Total operating cost hit 2.260 dollars per mile on 2024 data, and with fuel stripped out the rest rose 3.6 percent to 1.779 dollars, a record. Empty miles run near 16 percent. The lines you control are wear, and wear is measured in the shop.

The most expensive mile ATRI has ever measured was not made expensive by diesel. In its analysis of the operational costs of trucking, the American Transportation Research Institute put the total cost of running a truck at 2.260 dollars per mile with 2024 data. Strip fuel out of that number and what is left rose 3.6 percent to 1.779 dollars per mile — the highest non-fuel operating cost ATRI has ever recorded.

Read that again, because it changes where you look. Fuel is the line everybody watches, the one posted in numbers three feet tall at every exit. The record was set by the lines nobody posts: tires, repairs, insurance, the truck payment, the driver.

Why the non-fuel number is the one that bites

Diesel goes up and diesel comes down, and when it goes up you can see it coming a week out. Non-fuel cost does not behave that way. It ratchets. An insurance premium that jumps does not come back down next quarter. A tire program that runs 20 percent short of its expected life does not correct itself. A truck that eats an extra set of steers every year has quietly rewritten your cost per mile, and no fuel island sign will ever tell you.

That is the difference between a price and a cost. Fuel is a price you pay. Non-fuel is a cost you build, one decision at a time, and most of it is built in the shop.

The 16 percent almost nobody prices

ATRI also puts empty miles at roughly 16 percent of non-tank truck operations. That is close to one mile in six burning fuel, wearing tires, adding hours and generating exactly zero revenue. Every cost per mile you calculate is being divided by miles that include those.

Private fleets are attacking it with software. US Foods reports about a 2 percent annual reduction in miles driven through route planning, and says it has cut 4.9 million miles since 2022 even while deliveries grew. Volvo says aerodynamic work on the VNL is worth close to 7 percent in fuel efficiency, and up to 10 percent on large sleepers in some configurations. On the pay side, Walmart says annual driver compensation can exceed 100,000 dollars — a reminder that the biggest non-fuel line is a person, not a part.

An owner-operator does not have a route planning department. What an owner-operator has is a truck that either runs straight or does not.

What actually moves your non-fuel number

Here is the honest version. You do not control insurance. You do not control what a new truck costs. You control wear, and wear is where the record was set.

• Alignment. A drive axle out of line makes the truck crab down the road while the steer tires scrub sideways to keep it straight. You pay for that twice: in fuel to overcome the drag, and in a set of steers that dies early.
• Tire pressure. Underinflation raises rolling resistance and cooks the casing from the inside. It is the cheapest thing on this list and the most skipped.
• Irregular wear. Feathering, cupping and one shoulder gone while the other looks new are not tire defects. They are the tire reporting a suspension or alignment problem in the only language it has.
• Idle time. Hours spent idling for climate control burn fuel and put engine hours on a truck that is not moving, which is non-fuel cost dressed up as fuel cost.

Run your own number before the quarter ends

Take your last twelve months. Add fuel, maintenance, tires, insurance, payments, permits and your own pay. Divide by every mile you turned, loaded and empty. That is your real cost per mile, and it is the only number that tells you whether a load pays.

Then do it a second time with fuel removed. If your non-fuel side is climbing while your miles hold flat, the truck is telling you something before it breaks. A free inspection at The Truck Savers puts numbers on that: alignment readings, tire wear patterns and suspension condition, measured rather than guessed. For idle hours, an APU takes climate control off the engine.

The record cost per mile was not set at the fuel island. It was set in a thousand small places where wear went unmeasured. Los fierros nunca mienten.
