Reefer vs Dry Van Cost Per Mile
Reefer freight pays more — and costs more. Here is the premium itemized, so you can tell whether the extra rate is profit or just reimbursement.
Where does the extra $0.19/mi go?
Four line items separate a reefer from a dry van. Same truck payment, same insurance base — the gap is fuel economy, cooling-unit fuel, maintenance, and cargo coverage:
| Cost item | Dry van | Reefer |
|---|---|---|
| Tractor fuel economy | 6.5 MPG | 6.1 MPG |
| Tractor fuel $/mi @ $6.20/gal | $0.95 | $1.02 |
| Reefer unit fuel | — | ~$760/mo (~$0.08/mi at 10k mi) |
| Maintenance reserve | $0.15/mi | $0.18/mi |
| Cargo insurance adder | — | ~$150/mo |
| Total premium vs dry van | baseline | ~+$0.19/mi |
How does the reefer-vs-dry-van math work?
At $6.20 diesel, tractor fuel costs $0.95/mi dry van ($6.20 ÷ 6.5) versus $1.02/mi reefer ($6.20 ÷ 6.1) — a $0.07 gap before the cooling unit burns a drop. Add ~$760/month reefer fuel spread over 10,000 miles ($0.076), $0.03 in extra maintenance reserves, and ~$150/month in cargo insurance adders ($0.015). Total: roughly $0.19 per mile. Run fewer than 10,000 miles and every monthly item costs more per mile — utilization punishes reefers faster, because more of their cost is monthly. Plug your own miles into the cost per mile calculator with the reefer preset and watch the break-even move.
Do reefer rates cover it?
Sometimes — and that is the whole decision. Produce, pharmaceutical, and food-service lanes often pay a premium over dry van, but it swings hard by lane, season, and direction. A $0.25/mi premium on a steady reefer lane beats the $0.19 cost and leaves real profit; a $0.08 premium on a backhaul-heavy lane means the dry van would have paid better. Never judge on the loaded rate alone: test every candidate lane in the load profit calculator with deadhead included, and add the fuel surcharge as its own line. Also budget the hidden reefer taxes: appointment delays, washouts between loads, and claim risk on temperature loads — all of which cost hours even when they don't cost dollars.
Which should you choose: reefer or dry van?
Choose dry van if you want the lowest break-even, simplest operations, and the widest load board — the easiest business to run profitably. Choose reefer if you have (or can build) steady temperature-controlled lanes whose premium clears $0.19/mi with margin, and you can live with night loading, stricter appointments, and higher upfront trailer cost. Either way the process is identical: compute your true break-even with your miles and your quotes, then refuse freight below it. Start with the dry van preset, then flip to the reefer preset and compare the two break-evens side by side.

Reefer vs dry van FAQ
How much more does reefer cost per mile than dry van?
About $0.19 per mile at typical 2026 figures: ~$0.07 from worse fuel economy (6.1 vs 6.5 MPG), ~$0.075 in reefer-unit fuel, ~$0.03 in extra maintenance, and ~$0.015 in cargo insurance adders.
Do reefer loads pay more per mile?
Often yes on produce, pharmaceutical, and food lanes — but the premium varies by lane and season. It must beat your ~$0.19 per mile extra cost, or the dry van pays better.
What MPG should I use for reefer vs dry van?
Start with 6.5 MPG dry van and 6.1 reefer, then replace both with your own three-tank average. A half-MPG error moves fuel cost several cents per mile.
Is reefer fuel IFTA-taxable?
Generally no. Cooling-unit fuel is off-road use — track it separately from propulsion fuel and run propulsion numbers through the IFTA calculator.
Can a reefer haul dry freight?
Yes, with the unit off — many operators take dry loads to reposition. Washouts, extra weight, and worse fuel economy still apply, so price those miles honestly.
Should a new owner-operator start with reefer?
Only if the numbers work on your lanes. Higher revenue potential, higher costs, more complexity. Model both setups in the cost per mile calculator before committing.
