Trucking Cost Per Mile: Calculate Your Real Break-Even Rate

A truck can produce strong weekly revenue and still lose money. Gross revenue does not show how much fuel, insurance, equipment, maintenance, payroll, tolls, deadhead, and financing consumed along the way.

Cost per mile turns those expenses into a number that can be compared with freight revenue. It helps a carrier answer three essential questions: what does it cost to move the truck one mile, what average rate covers the business, and what rate is needed to produce the desired profit.

The calculation is simple. The hard part is including every cost and using every mile.

What cost per mile means

The basic formula is: total cost per mile = total operating costs for the period divided by total miles for the period.

Use all miles driven for business. Loaded miles, empty miles, repositioning, maintenance trips, and other operational movement all consume resources.

If the carrier spends $19,500 during a month and the truck runs 10,000 total miles, the cost is $1.95 per total mile.

That number is the operating cost, not the target selling price. The target rate must also support profit, reserves, and any cost that has not been included.

Why an industry average is not your break-even rate

ATRI reported in July 2026 that the industry average cost to operate a truck during 2025 was $2.336 per mile. That figure is useful because it shows the scale of modern trucking costs and provides a comparison point.

It is not a universal minimum rate. A paid-off truck with a strong insurance history may operate below the average. A new venture with expensive insurance, high equipment payments, poor fuel economy, or low monthly utilization may operate well above it.

The correct number comes from actual business records.

Step 1: Choose a useful period

Start with one month if the business is new. Use a rolling three-month or six-month view once enough records exist.

A single month can be distorted by a large repair, an annual premium payment, or unusual downtime. A rolling view shows whether the cost is moving in the right direction while still reacting to current conditions.

Use the same period for expenses and mileage. Do not divide one month's expenses by mileage from a different period.

Step 2: List fixed costs

Fixed costs continue even when the truck is parked. Some remain completely fixed, while others change only when the business adds equipment, drivers, or coverage.

Common fixed costs include:

• Truck and trailer payments.
• Commercial insurance premiums.
• Office and parking expense.
• ELD, software, phone, and subscription costs.
• Accounting, legal, registration, and administrative expense.
• Salaried management or support labor.
• Annual permits, plates, and fees converted to a monthly amount.
• Depreciation if the business uses it for management reporting.

Convert annual and quarterly expenses into a monthly amount. If an annual registration costs $1,200, include $100 per month in the model rather than allowing the renewal month to carry the entire cost.

Owner compensation needs deliberate treatment. If the owner drives, decide how the model will recognize the driver's labor and the owner's return on the business. Treating all remaining cash as profit hides whether the driving job and the company are each paying adequately.

Step 3: List variable costs

Variable costs generally increase as the truck works more miles or completes more loads.

Common variable costs include:

• Diesel and diesel exhaust fluid.
• Driver wages or mileage pay.
• Fuel taxes.
• Tolls and route permits.
• Maintenance and repairs.
• Tires.
• Factoring or quick-pay fees.
• Dispatch fees when based on revenue or loads.
• Lumper, washout, scale, and loading expense not reimbursed.
• Cargo claims and deductibles.

Some costs are mixed. Maintenance has a mileage component, but a major repair can occur unexpectedly. Insurance is usually treated as fixed, but the premium can change after an equipment or driver change. The goal is a useful operating model, not a perfect accounting label.

Step 4: Create maintenance and tire reserves

Waiting until a repair occurs makes a profitable month look excellent and the repair month look disastrous. A reserve spreads expected cost across the miles that create the wear.

One method: maintenance reserve per mile = expected annual maintenance and repair cost divided by expected annual miles.

Create a separate tire reserve if that makes the records easier to manage. Update both amounts when actual experience changes.

Keep the cash reserve in a real account when possible. An amount shown in a spreadsheet does not pay for an engine, tow, or set of tires.

Step 5: Count every mile

Total miles should come from reliable odometer, ELD, telematics, or dispatch records. Reconcile the source with fuel and maintenance records.

Separate the miles into useful categories:

• Loaded miles.
• Deadhead to pickup.
• Repositioning after delivery.
• Personal conveyance when applicable to the carrier's accounting policy.
• Maintenance and shop movement.
• Other business miles.

The total is used for cost per mile. The categories explain why the number changed.

Step 6: Calculate fixed, variable, and total cost

Assume one truck has these monthly results:

The calculations are: fixed cost per mile = $7,400 divided by 10,000 = $0.74. Variable cost per mile = $12,100 divided by 10,000 = $1.21. Total cost per mile = $19,500 divided by 10,000 = $1.95.

If the truck generated $24,000 in linehaul and accessorial revenue, revenue per total mile was $2.40. The operating margin before taxes and any excluded owner return was $0.45 per total mile, or $4,500 for the month.

Step 7: Add a profit target

Break-even means revenue equals cost. It does not fund growth or reward business risk.

A simple target: required revenue per total mile = total cost per mile + desired profit per total mile. If cost is $1.95 and the desired profit is $0.25 per total mile, the target becomes $2.20 per total mile.

A percentage margin can also be used. Be careful with the difference between markup and margin. Adding 15 percent to cost is not the same as earning a 15 percent margin on revenue. For a target margin: required revenue = cost divided by 1 minus the target margin. If a trip costs $1,560 and the target margin is 15 percent, required revenue is approximately $1,835. This calculation should be reviewed with an accountant if it becomes part of formal financial reporting.

Step 8: Convert the target into a load quote

Suppose a load has 700 loaded miles and 100 miles of deadhead. Total trip miles are 800. With a target of $2.20 per total mile, required trip revenue = 800 multiplied by $2.20 = $1,760.

The loaded-mile rate shown by a load board would be $1,760 divided by 700 loaded miles, or approximately $2.51 per loaded mile. This is why a carrier cannot compare a loaded-mile offer directly with a total-mile cost.

Add costs that are unique to the trip and not already included, such as unusual permits, expensive tolls, an escort, ferry charges, or a planned overnight delay. Confirm whether reimbursements are included in the rate or paid separately.

Step 9: Measure time as well as miles

Some loads fail because they consume too much time rather than too many miles. A 250-mile load with a morning pickup and next-day delivery may occupy most of two working days.

Track revenue per working day and revenue per on-duty hour alongside revenue per mile. For local and regional work, time may be the more important constraint.

A useful load review asks:

• How many hours will loading and unloading require?
• Does the appointment prevent another load that day?
• Will the truck arrive after the destination market stops booking?
• Is overnight parking available?
• Does the schedule create a legal hours problem?

Step 10: Review the model every month

Update actual revenue, expenses, mileage, and utilization. Compare the result with the prior month and rolling average.

Investigate changes in:

• Fuel cost per mile.
• Maintenance cost per mile.
• Driver cost per mile.
• Insurance cost per mile.
• Deadhead percentage.
• Average revenue per total mile.
• Revenue per working day.
• Days out of service.

The U.S. Energy Information Administration publishes weekly diesel price data. That data can help explain market movement, but the carrier's own fuel purchases and fuel economy determine the true fuel cost per mile.

Common cost per mile mistakes

• Using loaded miles instead of total miles.
• Leaving owner labor out of the calculation.
• Ignoring annual fees and irregular expenses.
• Recording repair bills without building a reserve.
• Treating factoring, quick-pay, or dispatch fees as invisible deductions.
• Comparing gross settlement revenue with a cost figure that excludes major expenses.
• Using an industry average as the carrier's exact break-even point.
• Setting one rate floor for every lane, season, and appointment pattern.
• Confusing cash in the bank with accounting profit.
• Failing to update the model when insurance, equipment, or utilization changes.
