Quick Take:
In 2025, the average diesel price hit just $3.57/gallon—the lowest in over two years—while fleets shelled out $44,327 per truck on fuel and owner-ops burned through roughly 20,500 gallons yearly (≈$70 000). When you bundle wages, truck payments, maintenance, insurance and permits, the total cost per mile lands around $1.30, based on $104 445 in annual expenses spread over 80 159 miles. Whether you’re cruising coast-to-coast or running local hauls, understanding each piece of the puzzle is the ticket to staying profitable on and off the road.
Ever noticed that paying for a diesel fill-up doesn’t sting quite as badly this spring? After years of volatility, U.S. diesel averaged $3.57 per gallon in April 2025, down from $4.00 a year prior. As U.S. crude dipped to $57.10/barrel in early May, drivers saw pump prices ease to a median $2.99/gal for gasoline—small relief, but real relief. Still, fuel remains the single biggest line item in any trucking budget, so even slight swings ripple through your bottom line.
Picture this: you roll into a Midwestern truck stop, and a fellow driver quips, “Back when diesel topped $5, I thought I’d have to refinance my house!” Thankfully, those days are behind us—at least for now. In 2025:
Every penny saved at the pump is profit in your pocket. With diesel on a mild downward trend—3.1 % lower year over year—drivers who track prices and change routes can shave off an extra few cents per mile.
If you think trucking pays the big bucks, you’re partly right—but after expenses, the math gets trickier. In 2025:
A quick coffee-shop lament often goes: “I drove 2 000 miles and only saw $800 in my pocket.” That’s why savvy drivers track not just miles, but every dime spent—knowing that every 0.01 ¢/mi saved on tires or tolls adds tangible earnings to your ledger.
Your truck isn’t just a workhorse—it’s a financed asset with payments that bite:
While payments might feel like a fixed overhead, remember that shopping for used trucks or negotiating loan terms can knock thousands off your annual tab.
Breakdowns don’t just strand you—they bleed cash:
Regular service intervals, proactive inspections, and shop loyalty programs can turn maintenance from a budget-busting surprise into a predictable line item.
No matter how smooth your drive, you can’t dodge these:
Insurance premiums jumped 12.5 % in 2025, making risk management and safe-driving discounts more valuable than ever.
Crunching annual expenses against miles traveled gives you your true cost per mile. Based on 2025 averages:
Category | Cost per Mile |
Fuel | $0.55–$0.64 |
Driver Wages & Benefits | $0.69–$0.78 |
Truck & Trailer Payments | $0.33 |
Maintenance & Repairs | $0.20 |
Insurance & Permits | $0.11–$0.19 |
Estimated Total | ≈$1.30 |
If you’re hitting 50 000 miles, your** cost per mile** might even climb to $1.50+ due to fixed fees—whereas running 130 000 miles can drive it down to around $1.10 as you spread those payments thinner.

She loves the freedom—her rig is her business. With a median gross of $186 k, she budgets $34 k for fuel, $24 k for payments, and $14 k for insurance, then hopes to clear $80 k net after 62 000 miles.
Fleet Driver Frank:
He trades that upside for stability: his company covers most overhead, he banks $57 k gross and takes home around $48 k, while enjoying per diems and no surprise repair bills.
Bottom Line:
Trucking in 2025 isn’t for the faint of heart, but savvy operators who track every expense—fuel, pay, maintenance, insurance, permits—can lock in profits. Use this guide and your own numbers in the Trucker Calculator to turn what feels like a guessing game into a precise, profit-driving plan.
