Ask ten owner-operators their cost per mile and half won’t have it to the penny. That’s the number a broker is really testing when the rate comes in low — whether you know your floor well enough to say no. Cost per mile is simple to define: total operating cost divided by total miles. It’s just easy to get wrong, because the biggest pieces are the ones you don’t write a check for every day.
The formula is fixed cost per mile + fuel per mile + maintenance per mile. Get those three honest and you have a floor you can price against at 9 p.m. when a load board lights up and you have four minutes to answer.
Three steps, one number
The same defaults the calculator above starts on: $6,090 fixed over 10,000 miles a month. It’s a cash floor — a wage for your own seat comes out of what’s left above it.
Sanity-check your number
ATRI reports an industry-average operating cost of $2.336 per mile for 2025 in its 2026 study. That fleet benchmark is useful context, not your personal cost floor. Equipment, mileage, fuel, compensation and the costs included in a calculation all change the result.
This calculator starts with a $1.49 sample truck cost per mile before your pay, taxes and load-specific expenses. Replace the sample with your bills and realistic miles. The new owner-operator cost guide helps you build a budget around quotes for your own operation.

Cost per mile is step one
Knowing you cost $1.49 a mile is worth nothing until a broker offers $2.25 for 700 loaded miles with 150 empty to the pickup. Then the number does its job: $1,575 spread over 850 real miles is $1.85 a mile the truck actually drives — still above the floor, but a lot thinner than the quoted rate made it sound.
That’s the move cost per mile sets up: judge every load across loaded plus deadhead, against your floor plus the margin you want. Our rate per mile calculator runs that check, and the load profit calculator turns it into a take, counter, or pass on a specific offer.
Straight answers
Add up your fixed monthly bills — truck payment, insurance, permits, ELD, parking, software — and divide by the miles you actually run in a month. Add fuel per mile (diesel price ÷ your real MPG) and a maintenance reserve per mile. The three together are your all-in cost per mile. On the sample profile used here that lands near $1.49 a mile; the calculator on this page shows the breakdown on your own numbers.
Your cost depends on your equipment, total miles, fuel, bills and compensation. ATRI reported an industry-average operating cost of $2.336 per mile for 2025 in its 2026 study. That historical fleet benchmark is not a personal owner-operator budget; use your own inputs and include your pay and load-specific expenses.
Two buckets. Fixed costs stay the same whether the truck moves or not: truck and trailer payment, insurance, plates and permits, ELD, parking, phone, accounting or software. Variable costs move with the miles: fuel and a maintenance reserve for tires, PMs, and repairs. Keep per-load costs like tolls, lumpers, and factoring fees separate — they belong on the specific load, not the monthly average.
Because fixed bills are spread over changing mileage. Your truck payment and insurance don't shrink when you run fewer miles, so a slow month spreads the same bills over less distance and your cost per mile climbs. Run 8,000 miles instead of 10,000 on $6,090 of fixed bills and your fixed cost per mile jumps from about $0.61 to $0.76 — the same truck, a worse floor.
Cost per mile is what your truck spends to run a mile. Rate per mile is what a load pays per loaded mile. Profit is the gap between them. Knowing your cost per mile is step one; the next step is checking a load's rate — across loaded plus deadhead miles — against that floor. Our rate per mile calculator does exactly that.
Yes — it runs right on this page with no account, no email, and no card. It starts on the sample profile used here so you can see the shape, then you change any field to your own numbers. When you want to check real loads against your floor, a 14-day solo trial starts with your first successful full check.
The two biggest levers are miles and MPG. Running more paid miles a month spreads your fixed bills — truck payment, insurance, permits — over more distance, so a slow month always raises your cost per mile; keeping the truck loaded moves the number more than trimming any single bill. On the variable side, MPG is what you control day to day: less idling, steady speeds, and correct tire pressure cut fuel cost per mile more than a fuel-card discount does. Refinancing a high truck payment and re-shopping insurance at renewal chip away at the fixed side.
It depends what you're deciding. For a break-even floor — the rate below which a load literally loses money — use cash cost per mile without your pay, which is what this calculator shows. When you're judging whether the business is worth running, add a driver wage per mile so your time isn't priced at zero. Most owner-operators track both: the cash floor for a go/no-go on a load, and the all-in-with-pay number for whether the month actually worked.

Backhaul keeps your cost profile once, pulls this week’s diesel automatically, and prices every load against your real floor — the route with tolls, deadhead, and the broker’s FMCSA record — then follows the math from decision to delivery to getting paid.
