Box Truck Cost Per Mile Calculator (2026)
Enter your fixed costs, fuel, maintenance and own pay to find your break-even per mile. Then check a load offer after unpaid pickup and return miles. All dollar amounts are USD.
Every mile counts.
What you keep on the whole load · before income tax
—All-in cost/mile = fixed ÷ monthly total miles + diesel ÷ mpg + maintenance/tires + your pay. Offer per total mile = offered rate × paid miles ÷ (paid + unpaid miles). Profit is after your entered pay, before income tax. Defaults are examples, not market rates.
Pricing a local delivery route? Per-mile math can miss time spent loading, unloading and waiting. Use the box-truck delivery pricing calculator to work out a route/day quote and price per paid stop from your hours and costs.
TruckMargin Pro saves your box truck's cost profile and checks any load against your real cost per mile in seconds — $9/mo founding rate.
See Pro →What it costs to run your box truck per mile
Your break-even includes both the truck and the work you do: monthly fixed costs spread over all miles, fuel, maintenance and tires, plus your own pay. Lower monthly mileage raises the fixed cost of every mile. An offered rate must cover unpaid travel too; a high paid-mile rate can hide a weak total-mile result.
2026 box truck cost per mile — the components
Illustrative component ranges for a non-CDL 26-ft diesel box truck at the October 19, 2026 diesel price. Your fixed cost per mile depends most on insurance and how many miles you actually run:
| Cost component | Modeled / mile | Why |
|---|---|---|
| Fuel | ~$0.63–$0.78 | About 8–10 mpg at $6.28 diesel |
| Maintenance & repairs | ~$0.10–$0.20 | Oil, brakes, belts; medium-duty parts |
| Tires | ~$0.03–$0.05 | Assumes a six-tire truck; replace with your actual tire budget |
| Fixed ÷ miles (payment, insurance, permits) | ~$0.30–$0.55 | Your insurance, payments and utilization determine this cost |
| Your pay | ~$0.40–$0.55 | Pay yourself a wage, or the truck only looks profitable |
| All-in | ~$1.46–$2.13 | Sum of component bounds, before profit |
Ranges are TruckMargin planning estimates; the total sums the low and high component bounds using EIA diesel ($6.276/gal, week of Oct. 19, 2026). Compare equipment assumptions in cost per mile by truck type.
What deadhead does to a $2.50-per-mile offer
These are worked scenarios, not market-rate benchmarks. Each example pays $750 for 300 paid miles and assumes an all-in cost of $1.65 per total mile, including owner pay. Add all unpaid travel needed for the job.
| Unpaid miles | Total miles | Revenue / total mile | Profit after modeled costs |
|---|---|---|---|
| 0 | 300 | $2.50 | $255.00 |
| 50 | 350 | $2.14 | $172.50 |
| 100 | 400 | $1.88 | $90.00 |
| 150 | 450 | $1.67 | $7.50 |
Profit = $750 − total miles × $1.65. The calculator uses your full-precision inputs; this table uses a separate rounded $1.65 scenario.
Per mile, per stop or per day?
For a highway load, compare revenue per total mile with your all-in cost. For local multi-stop delivery, also price your time: ten stops at 20 minutes each add 3 hours 20 minutes before loading and driving. A fixed mileage allowance alone does not show that workload.
The delivery-route pricing tool separates vehicle costs, hourly driver/helper pay, overhead and profit. It shows how longer stops and fewer billable stops change the quote you need. Use its time-based model for local work; do not add this page's all-in cost on top of its wages and overhead, which would count those costs twice.
Set a rate from your costs
There is no verified national box-truck rate average in this tool. Quotes depend on the lane, equipment, service requirements, timing and customer. Start with your own break-even, include all travel and work time, then compare the actual offers available to you. The rate-per-mile calculator also converts a flat load payment into a total-mile rate.
Frequently asked questions
What is the average cost per mile for a box truck?
The component-based model on this page sums to about $1.46–$2.13 per mile including owner pay, using 8–10 mpg and $6.276/gal diesel for the week of October 19, 2026. This is a planning range, not a measured industry average. Insurance, payments, and miles can move your result outside it.
What is the average box truck rate per mile in 2026?
This page does not claim a verified national box-truck rate average. Compare actual offers with your costs after unpaid miles. For example, $2.50 per paid mile on 300 paid miles yields $750; with 100 unpaid miles, that is $1.875 per total mile before costs. Local delivery also needs an allowance for loading and time at each stop.
Do you need a CDL to drive a box truck?
Under federal rules, a single vehicle generally requires a Class B CDL when its GVWR or actual gross weight is 26,001 pounds or more, whichever is greater. A qualifying combination can require Class A. Even below those weight thresholds, certain hazardous materials or passenger operations require a CDL. States may impose additional requirements; truck length alone does not determine licensing.
Why can a box truck cost less per mile than a semi?
A smaller truck may have lower payments, fuel use and tire costs, but insurance and utilization can outweigh those savings. The six-tire, 8–10 MPG example here is a planning model, not a guarantee for every box truck. Use your own costs and mileage.
How do I know if a box truck load is worth it?
Multiply the offered rate by paid miles, then divide the revenue by all miles including unpaid pickup and return travel. Compare that result with your all-in cost per mile. For local delivery, also account for loading, waiting, stop time and helper pay in the delivery-pricing calculator.
Methodology & sources
All-in cost/mile = monthly fixed ÷ monthly total miles + diesel ÷ mpg + maintenance and tires per mile + owner pay per mile. Effective offered rate = paid-mile rate × paid miles ÷ total miles. Cost ranges and load examples are TruckMargin planning scenarios, not measured market averages. Diesel default: $6.276/gal, U.S. EIA on-highway average, week of October 19, 2026.
