The Number That Runs Your Business
Your cost per mile is the single most important number in your trucking business. Get it wrong, and every load decision you make is based on bad data. Get it right, and you'll know instantly whether any rate is worth your time.
The industry average cost per mile for owner-operators is $1.50 to $2.20. But averages are dangerous — your number could be $1.30 or $2.50 depending on your truck, your insurance, your fuel efficiency, and a dozen other factors.
Here's how to calculate YOUR number.
Fixed Costs (They Don't Care How Many Miles You Run)
Fixed costs hit your bank account every month whether you run 10,000 miles or zero. That's what makes them dangerous — when you're sitting, they're still burning.
| Fixed Cost | Monthly Range | Notes |
|---|---|---|
| Truck payment | $1,500 - $2,800 | Depends on new vs. used, terms |
| Insurance | $800 - $2,000 | Liability, physical damage, cargo, bobtail |
| Permits & licensing | $100 - $300 | IRP, IFTA, UCR, authority renewal |
| Health insurance | $400 - $1,200 | Often overlooked |
| Accounting/bookkeeping | $100 - $300 | Software or CPA |
| Phone/ELD/subscriptions | $100 - $250 | ELD, load boards, apps |
| Trailer payment | $0 - $800 | If you own/lease a trailer |
Typical monthly fixed costs: $3,000 - $7,500
How to Convert to Per-Mile
If you run 8,000 miles per month:
- Low end: $3,000 ÷ 8,000 = $0.38/mile in fixed costs
- High end: $7,500 ÷ 8,000 = $0.94/mile in fixed costs
This is why miles matter. The more miles you run, the lower your fixed cost per mile. But running cheap miles just to lower this number is a trap — a $1.40/mile load doesn't help you if your variable costs eat the rest.
Variable Costs (They Scale With Every Mile)
| Variable Cost | Per-Mile Range | Notes |
|---|---|---|
| Fuel | $0.45 - $0.75 | Biggest variable: depends on MPG and diesel price |
| Maintenance reserve | $0.10 - $0.20 | Tires, oil, brakes, unexpected repairs |
| Tires | $0.03 - $0.06 | Amortized per mile |
| Tolls | $0.02 - $0.10 | Highly route-dependent |
| Lumper/accessorial | $0.01 - $0.05 | Loading/unloading fees |
| Scale tickets | $0.01 - $0.02 | Weigh station charges |
Typical variable cost: $0.65 - $1.15/mile
The Fuel Deep Dive
Fuel is usually 30-40% of your total costs. Your per-mile fuel cost depends on:
- Diesel price: $3.50 - $4.50/gallon (varies by region and season)
- Your truck's MPG: 5.5 - 7.5 MPG for most Class 8 trucks
- Route terrain: Mountains vs. flatland can swing your MPG by 1-2 points
Formula: Diesel price ÷ MPG = Fuel cost per mile
At $4.00/gallon and 6.5 MPG: $4.00 ÷ 6.5 = $0.62/mile in fuel
The Costs Most Truckers Forget
Here's where the gap between your "estimated" cost per mile and your REAL cost per mile lives:
1. Deadhead Miles
When you drive 200 miles empty to pick up a load, those miles cost you fuel and time but pay you nothing. If 15% of your total miles are deadhead, your effective cost per mile on loaded miles is 15% higher than you think.
2. Days, Not Just Miles
A $2,500 load over 1,000 miles looks great at $2.50/mile. But if it takes 3 days including loading/unloading wait times, your daily profit might be worse than a $1,800 load over 800 miles that you complete in 1 day.
3. Destination Market
Delivering to a freight hub like Dallas or Chicago means immediate reload options. Delivering to rural Montana means you might deadhead 300 miles to find your next load. That deadhead cost should be factored into the FIRST load's profitability.
4. Overhead Allocation
Your time has value. If you spend 2 hours booking a load, doing paperwork, and waiting at a shipper, that's time you're not driving. Smart operators allocate their time as a cost.
5. Seasonal Fuel Variation
Diesel prices swing 20-30% between seasons. If you calculated your cost per mile in summer, it might be significantly wrong in winter.
Putting It All Together
| Category | Low End | High End |
|---|---|---|
| Fixed costs per mile | $0.38 | $0.94 |
| Variable costs per mile | $0.65 | $1.15 |
| Total cost per mile | $1.03 | $2.09 |
Your number is somewhere in that range. The only way to know exactly is to add up YOUR costs — not the industry average.
What To Do With Your Number
Once you know your true cost per mile:
- Any load below your CPM is a loss. No exceptions, no "but it gets me to a good area." The math doesn't lie.
- Target 20-30% margin above your CPM. If your CPM is $1.60, target loads at $2.00/mile or higher.
- Recalculate quarterly. Fuel prices change. Insurance renewals change. Your CPM shifts.
- Factor in deadhead and destination. A $2.00/mile load to a dead zone costs more than a $1.85/mile load to a freight hub.
The Better Way
Calculating your cost per mile by hand is essential — every owner-operator should do it at least once to truly understand their numbers.
But evaluating every individual load against that number, while also accounting for deadhead, destination market, tolls, and multi-day overhead? That's where the manual process breaks down.
The truckers who make the most money aren't the ones with the best spreadsheets. They're the ones who see their profitability on every load instantly, compare dozens of options in seconds, and pick the best one — not just the first one that passes the math test.
