What's the average trucking cost per mile in 2026?
The American Transportation Research Institute (ATRI) put the industry-average marginal cost of operating a truck at about $2.26 per mile in 2024, with non-fuel costs at a record ~$1.78/mile. For a solo owner-operator, the all-in number — fixed costs + fuel + maintenance, tires and DEF + your own pay, divided by the miles you actually run — usually lands between $1.80 and $2.20 per mile, depending on your truck payment, fuel economy, and monthly miles. That all-in figure is your break-even rate: the price per total mile (loaded + deadhead) a load must beat before it makes you a dime. The calculator above works it out from your real numbers in seconds, and the load checker tells you instantly whether a rate clears it.
How to calculate your trucking cost per mile
Your cost per mile (CPM) is the single most important number in an owner-operator business. It's what separates a load that builds your business from one that quietly drains it. The formula is simple — total costs ÷ total miles — but the accuracy lives in the details.
There are three buckets to add up:
- Fixed costs — what you pay whether the wheels turn or not: truck and trailer payments, insurance, permits, IFTA, plates, ELD and software subscriptions, parking. Spread these across the miles you actually run each month.
- Variable costs — costs that rise with miles: fuel (the big one), maintenance and repairs, tires, and DEF. Fuel per mile is just diesel price ÷ your real MPG.
- Your pay — the wage you owe yourself. Leaving this out is the most common mistake owner-operators make, and it's why a "profitable" truck can still leave you broke.
Add those three per-mile numbers together and you have your true all-in CPM — your break-even rate. Most owner-operators land somewhere between $1.80 and $2.20 per mile all-in, but yours depends on your payment, your fuel economy, and how many miles you run. Recalculate it every quarter, and any time fuel spikes, insurance renews, or you take on a new payment.
What's a good rate per mile in 2026?
As a quick gut-check, mid-2026 national-average spot rates sit near $3.00/mi for dry van, $3.39/mi for reefer, and $3.69/mi for flatbed, including fuel surcharge. Those track DAT's June 2026 national benchmarks — dry van spot topped contract for the first time since February 2022 and flatbed set a record high, with the market historically tight but cooling seasonally off the June peak into mid-July. Those are national averages; your lane, season, and equipment move them a lot, so check current numbers on our rate-per-mile calculator and crowd-sourced lane rates before you quote. The number that actually matters is the rate per total mile (including your deadhead) measured against your cost per mile. A $3.00/mi load with 200 miles of deadhead can pay less than a $2.40/mi load right under your wheels — exactly what the load checker above figures for you.
