Owner Operator Cost Per Mile: How to Find Your Break-Even Before You Lease On (2026 Texas Guide)

Diesel is over $6. Do you know what a mile costs you?

The U.S. Energy Information Administration put the national average for on-highway diesel at $6.276 a gallon for the week of Oct. 19, 2026, up about $2.66 from a year earlier. The Gulf Coast average, which covers Texas, was $5.903. Brent crude hit $116 on Oct. 23 (see this week's trucking news roundup). When fuel moves like that, the owner-operators who stay in business are the ones who know their own cost per mile to the penny — and turn down the loads that do not cover it.

This guide shows you how to work out your owner operator cost per mile, split it into fixed and variable costs, find your break-even on percentage pay, and use that number every time dispatch offers you a load. It is written by Maas Logistics LLC, an asset-based dry van and reefer carrier in Melissa, Texas, on the north side of DFW. We lease on owner-operators at 87–90% of gross with non-forced dispatch, so we would rather you show up knowing your numbers.

Everything below uses your numbers. The dollar figures in the examples are made-up round numbers to show the arithmetic. They are not Maas rates, quotes or pay promises.

What the industry averages say (and why they are not your number)

Every year the American Transportation Research Institute (ATRI) surveys fleets on what it costs to run a truck. Its 2026 report, released July 15, 2026, found that the industry-average cost to operate a truck in 2025 was $2.336 per mile, up 3.4% from the year before and the highest in the report's history. Without fuel, costs rose 4.2% to $1.854 per mile. The biggest percentage jumps were tolls, repair and maintenance, driver benefits and tires.

Those are useful benchmarks, but they are fleet averages. They include company-driver wages and benefits, office staff and fleet-scale truck buying. A one-truck owner-operator pays some things a fleet does not (your own insurance, your own downtime) and skips others (no office payroll). Your truck's age, your fuel mileage, your lanes and your truck payment can put you well above or below the average. Use ATRI to sanity-check your math, not to replace it.

Step 1: List your fixed costs (you pay these parked or rolling)

Fixed costs show up whether you run 2,000 miles a week or zero. Pull 12 months of statements and add up the monthly amount for each:

• Truck payment or lease payment (and trailer, if you own one)
• Insurance you pay — primary liability if you run your own authority, plus physical damage, bobtail/non-trucking liability, occupational accident, cargo, as your setup requires. Your lease agreement spells out what the carrier covers and what you cover; read it line by line.
• Permits, plates and registration (IRP plates, heavy vehicle use tax, any state permits), spread monthly
• ELD, phone and data plans, load or business software
• Accounting, tax prep and any business loans
• Health insurance and retirement you pay yourself, if you count them as business costs (you should — nobody else is paying them)
• Parking or yard rent, if you pay it

Add them up for the year, then divide by the miles you actually ran in those same 12 months (all miles, loaded and empty). That is your fixed cost per mile.

Example (made-up numbers): $54,000 a year in fixed costs ÷ 110,000 total miles = $0.49 per mile. Notice what happens if you only run 90,000 miles: the same $54,000 becomes $0.60 per mile. Fixed costs punish downtime — that is why sitting is so expensive.

Step 2: List your variable costs (they grow with every mile)

Variable costs rise and fall with the miles you run:

• Fuel — usually the biggest line
• DEF
• Tires
• Repair and maintenance — oil changes, brakes, injectors, aftertreatment, breakdowns. Set aside money every mile even in a good month.
• Tolls and scales
• Truck washes, lumper fees you are not reimbursed for, and other road costs
• Your own pay. If you do not pay yourself per mile, your "profit" is really your wages.

Fuel cost per mile is simple math

Fuel cost per mile = price per gallon ÷ miles per gallon.

Example (made-up mpg, real EIA price): At the Gulf Coast average of $5.903 and 6.5 mpg, fuel costs about $0.91 per mile. At the national average of $6.276 and the same 6.5 mpg, it is about $0.97 per mile. Drop to 6.0 mpg and the national-price number climbs to about $1.05. Half a mile per gallon is worth roughly 7 to 8 cents a mile at today's prices — that is idle time, speed and tire pressure, not luck.

Track every fill-up against your ELD miles for a month. Your real mpg, not the sticker number, goes into the formula.

Maintenance and tires: reserve per mile

Look back at 12 months of shop and tire bills and divide by the miles you ran. If your truck is older or out of warranty, use a bigger number than last year's. Put that amount per mile into a separate maintenance account every settlement. When the big repair hits, the money is already there.

Step 3: Add it up — your all-in cost per mile

All-in cost per mile = fixed cost per mile + variable cost per mile (including what you pay yourself).

Example (made-up numbers): $0.49 fixed + $0.97 fuel + $0.20 maintenance and tires + $0.06 tolls, DEF and other road costs = $1.72 per mile before you pay yourself. Add the per-mile wage you want to take home, and that total is the number every load has to beat.

Write your number down. Update it every month when fuel moves, and every time your truck payment, insurance or mileage changes.

Step 4: Find your break-even on percentage pay

When you lease on at a percentage of gross, the carrier keeps a share of the load revenue and you keep the rest — at Maas, owner-operators keep 87–90% of gross. Before you compare percentage deals, read what "percentage of gross" should include and ask any carrier, in writing, exactly what is counted in gross and what gets deducted from your settlement.

To find the gross revenue per mile a load must pay for you to break even:

Break-even gross per mile = your all-in cost per mile ÷ your percentage.

Example (made-up numbers): With a $1.72 all-in cost:

• At 87%: $1.72 ÷ 0.87 = about $1.98 gross per mile to break even
• At 90%: $1.72 ÷ 0.90 = about $1.91 gross per mile to break even

And remember to count all the miles. A load that pays well on loaded miles can lose money once you add the deadhead to get to it. Divide the load's gross by loaded plus empty miles before you compare it with your break-even.

Step 5: Use the number on every load offer

Knowing your cost per mile only helps if you are allowed to act on it. That is the point of non-forced dispatch: you can look at a load, run your numbers and say no when it does not pay. On forced dispatch, you take what you are given. We explain the difference in forced vs. non-forced dispatch for owner-operators. Maas runs non-forced dispatch.

A quick load check before you say yes:

1. Total miles = loaded miles + deadhead to pickup.
2. Your share = load gross × your percentage.
3. Your share ÷ total miles = what you actually earn per mile.
4. Compare it with your all-in cost per mile. Is the gap worth the days and the hours of service it takes?
5. Think about where it leaves you. A load into a weak freight market can cost you a long deadhead out.

Dry van vs. reefer: costs are not the same

If you pull a reefer trailer you own, the reefer unit burns its own fuel and needs its own maintenance, so your variable cost per mile is higher. Reefer freight often pays more for that reason, but only your numbers can tell you whether the difference covers it. If you are deciding between the two, read dry van vs. reefer CDL jobs in Texas. Maas hauls both dry van and reefer full truckload, OTR in the 48 states.

Five ways Texas owner-operators lower cost per mile

1. Run more productive miles. Fixed costs spread across more miles cost less per mile. Cut empty miles and long waits wherever you can.
2. Fix fuel economy before you chase rates. Idle less, ease off the speed, keep tires at pressure and alignment in spec. Every tenth of an mpg counts at $6 diesel.
3. Fuel where it is cheaper. Gulf Coast diesel averaged about 37 cents less than the national average the week of Oct. 19, 2026. Plan fuel stops along your route instead of filling wherever the light comes on.
4. Keep a maintenance reserve. Preventive maintenance is cheaper than a tow and a week down.
5. Know your settlement. Read every deduction, every week. If you do not understand a line, ask until you do.

Owner-operator or company driver? Run the numbers both ways

Not every driver should own a truck. If the math above shows thin margins on your truck, compare it with a company driver job where the carrier pays for the truck, fuel and maintenance. Maas company drivers earn 50+ CPM dry van and 60+ CPM reefer — see how per-mile pay works in CPM pay explained, and apply as a company driver if that fits you better.

If you own your truck and want to lease on, start with our owner-operator lease-on guide for Texas, then look at owner-operator jobs in Dallas and apply as an owner-operator.

For shippers: why carrier costs show up in your rate

Fuel, repairs, tires and insurance all landed on truck costs in 2025, and diesel is higher again this fall. That is why a good quote shows the base rate and fuel separately. Our guide on how freight quotes are priced walks through it. Maas is asset-based and never re-brokers freight. Request a dry van or reefer quote.
