What This Calculator Does
This trucking cost per mile calculator computes the all-in cost per mile (CPM) for trucking operations by breaking down every major expense category: fuel, driver compensation, truck payments, insurance, maintenance, tires, permits, tolls, IFTA taxes, technology, and depreciation. It calculates annual totals, per-mile costs, and the percentage each category contributes to total operating cost. When revenue per mile is provided, the calculator also shows profit per mile, annual profit, and break-even mileage. Results are benchmarked against 2026 ATRI (American Transportation Research Institute) trucking cost data.
The Formula
Total operating cost includes all fixed costs (insurance, permits, truck payment, depreciation) and variable costs (fuel, maintenance, tires, tolls) divided by total miles driven. Fuel cost is calculated as (Annual Miles / MPG) x Price per Gallon. Driver pay is annualized from salary, per-mile rate, or hourly rate. The break-even point shows the minimum miles needed per year to cover all costs at the given revenue rate.
Step-by-Step Example
Enter mileage and revenue
Owner-operator running 120,000 miles per year with average revenue of $2.50 per loaded mile.
Calculate fuel cost
At 6.5 MPG and $3.75/gallon: 120,000 / 6.5 = 18,462 gallons x $3.75 = $69,231 annual fuel ($0.577/mile).
Add all fixed and variable costs
Truck payment: $28,800. Insurance: $12,000. Maintenance: $16,000. Tires: $4,500. Permits: $3,000. Tolls: $5,000. IFTA: $2,500. ELD: $1,500. Depreciation: $15,000. Driver pay: $75,000.
Calculate CPM and profit
Total annual cost: $232,531. CPM: $1.938. Profit per mile: $2.50 - $1.94 = $0.56. Annual profit: $67,469. Break-even: 93,012 miles.
Real-World Use Cases
Rate Negotiation
Knowing your exact CPM allows you to set minimum rate thresholds when negotiating loads. If your all-in CPM is $1.85, you know any load below that rate loses money.
Fleet Benchmarking
Fleet managers compare CPM across trucks and drivers to identify which units are most and least efficient, targeting maintenance, fuel, or route improvements.
Buy vs. Lease Analysis
Comparing the CPM impact of purchasing versus leasing a truck by changing the truck payment and depreciation inputs shows the true per-mile cost difference.
Common Mistakes to Avoid
Not including all cost categories. Many owner-operators forget to include depreciation, IFTA taxes, ELD technology fees, and permits. Omitting even one category understates true CPM by $0.05 to $0.15.
Using gross miles instead of paid miles. If 15% of your miles are deadhead (empty), your effective CPM on paid miles is significantly higher. Track paid miles separately.
Not updating fuel cost regularly. Diesel prices fluctuate significantly. Recalculate CPM monthly or whenever fuel prices change by more than $0.25 per gallon.
Ignoring the impact of truck age. Older trucks have lower payments but higher maintenance and worse fuel economy. A 10-year-old truck may have a higher all-in CPM than a new truck despite no truck payment.
