Trucking Cost Per Mile Calculator

What is trucking cost per mile?

Trucking cost per mile is an estimate of how much it costs your operation to move the truck one mile. Knowing this number gives owner-operators and small carriers a stronger starting point for evaluating rates, estimating profit, setting revenue targets and deciding whether a load makes financial sense.

A useful cost-per-mile estimate should include more than fuel. Truck payments, insurance, permits, maintenance, tires and other operating expenses can materially change the real cost of running the truck.

Trucking cost per mile formula

Torz Freight uses the following planning formula:

(Monthly fixed costs ÷ Monthly miles) + (Fuel price ÷ MPG) + Other variable cost per mile

This separates your monthly fixed expenses from costs that increase as the truck travels more miles.

Fixed trucking costs

Fixed costs are expenses your business generally has to pay even when the truck is not moving. Depending on your operation, these may include:

• Truck and trailer payments
• Commercial insurance
• ELD or technology subscriptions
• Permits and registrations
• Parking or yard costs
• Accounting and business services
• Other recurring monthly expenses

The calculator divides your monthly fixed costs by your expected monthly miles to estimate the fixed-cost portion of each mile.

Variable trucking costs

Variable expenses generally increase as the truck runs more miles. Fuel is usually one of the largest, but it should not be the only expense considered.

Other variable cost per mile may include items such as:

• Maintenance reserve
• Tire reserve
• Oil and service costs
• Repairs
• DEF
• Wash expenses
• Other mileage-based operating costs

Example cost per mile calculation

Suppose an owner-operator has:

• $4,000 in monthly fixed costs
• 10,000 monthly miles
• $3.75 diesel price per gallon
• 7 MPG
• $0.25 per mile in other variable costs

Fixed cost per mile: $4,000 ÷ 10,000 = $0.40

Fuel cost per mile: $3.75 ÷ 7 = about $0.54

Add the other variable cost: $0.25 per mile

Estimated total trucking cost per mile: about $1.19 per mile

This is a planning example only. Your real operating cost will depend on your equipment, mileage, fuel economy, insurance, maintenance history and business structure.

Why cost per mile matters when choosing loads

A load can look attractive based on the gross rate while still producing a weak result after deadhead, fuel, operating costs and fees are considered.

Cost per mile gives you a baseline. From there, you can compare the load's revenue against your estimated cost and determine whether enough margin remains for owner pay and business profit.

For a more complete load-level calculation, use the Load Profit Calculator.

How deadhead affects trucking profitability

Empty miles still consume fuel, tires, maintenance and driver time. That is why evaluating only loaded miles can make a rate look better than it really is.

When estimating monthly operating cost, use realistic business mileage that reflects the miles your truck actually travels. When evaluating a specific load, calculate loaded and empty miles together.

You can also use the Deadhead Cost Calculator and True RPM Calculator to evaluate the effect of empty miles.

Cost per mile vs. rate per mile

Cost per mile and rate per mile are not the same thing.

Cost per mile estimates what it costs you to operate the truck.

Rate per mile measures the revenue earned from freight.

Your rate needs to cover operating cost before the remaining amount can contribute to owner pay, taxes, reserves and profit.

Use the Break-Even RPM Calculator to estimate the minimum gross RPM needed to cover your operating cost and percentage-based fees.

Frequently asked questions

What should I include in trucking cost per mile?

Include both fixed expenses and mileage-related operating costs. Common categories include truck payments, insurance, fuel, maintenance, tires, permits, subscriptions and other recurring business expenses.

Should owner pay be included in cost per mile?

That depends on how you use the number. Some operators calculate basic operating cost first and then add owner compensation and profit targets separately. The important thing is to use the same method consistently when comparing loads and setting rates.

Should I use loaded miles or total miles?

For an overall operating-cost estimate, total business miles are generally more useful because the truck still incurs expenses while empty. For individual loads, consider both loaded miles and deadhead miles.

How often should I recalculate cost per mile?

Recalculate whenever major expenses change and review the number regularly as fuel prices, maintenance costs, insurance, mileage and equipment expenses change.

Does a higher rate per mile always mean a better load?

No. Deadhead, total miles, fuel usage, fees, time and operating cost can change the real result. Compare the full economics of the load rather than relying only on the advertised loaded rate.
