What it actually costs owner-operators to run each kind of truck — and how to find your own number in under a minute.
Your cost per mile (CPM) is the break-even line every load has to clear. It varies a lot by equipment: a reefer burns extra fuel running its cooling unit, a flatbed carries securement and tarping costs, and a non-CDL box truck has far lower payments and fuel burn than a Class 8 sleeper. The table below shows typical all-in CPM ranges (including the driver's own pay) for each equipment type in 2026, alongside recent national average spot rates for context.
| Equipment | Typical all-in CPM | Avg spot rate* | Why it differs |
|---|---|---|---|
| Dry van | $1.70 – $2.05 | ~$2.79 | The baseline; lowest specialized costs. |
| Reefer | $1.95 – $2.35 | ~$3.12 | Reefer-unit fuel + extra maintenance and washouts. |
| Flatbed | $1.85 – $2.25 | ~$3.60 | Straps, chains, tarps, and heavier/awkward freight. |
| Box truck (non-CDL) | $1.10 – $1.50 | ~$1.50 – $2.00 | Lower payment and fuel burn, but lower rates too. |
| Hotshot (1-ton + gooseneck) | $1.20 – $1.70 | ~$1.50 – $2.20 | Low fixed cost, smaller loads, more deadhead. |
*National average spot rates including fuel surcharge, mid-2026. Ranges are TruckMargin estimates built from typical fixed costs (payment, insurance, permits), fuel at ~6.5 mpg, maintenance/tires, and owner pay. Estimates only — your lane, season, and equipment will move these.

All-in CPM = (monthly fixed costs ÷ miles) + (diesel price ÷ mpg) + maintenance/tires per mile + your pay per mile. The biggest swing factors are your truck payment, your real fuel economy, and how many miles you actually run — fixed costs spread thinner the more you drive, which is why low-mileage months quietly raise your CPM.
The refrigeration unit burns its own diesel and needs separate maintenance, and reefer freight often involves washouts and stricter handling — adding roughly $0.15–$0.30/mi over an equivalent dry van.
Per mile, yes — lower payments and better fuel economy. But box-truck rates are also lower, so margins can be similar. Run your own numbers above.
