Cost Per Mile in Trucking: How to Calculate and Reduce It

Cost per mile is the total cost of running your trucks for every mile they drive. The formula: (Fixed Costs + Variable Costs) / Miles Driven = Cost Per Mile, calculated over the same period. Know that number and you know which loads make money and which do not.

This guide breaks down what goes into your cost per mile, how to calculate it by hand with a worked example, and six practical ways to bring it down. If you would rather not do the math yourself, a TMS like TransPlus tracks cost per mile for you on every trip.

How to Find Your Total Cost Per Mile

What Does Cost Per Mile Mean?

Cost per mile refers to the total cost to operate your fleet on a per-mile basis. This number will help you determine the total cost to own your fleet, thus helping you make better, more data-driven decisions that can improve your profits and optimize your fleet operations. Plus, having an understanding of your total cost per mile will make it easier to bid on potential loads and determine the return on investment for your jobs.

How to Find Your Cost Per Mile

Calculating your cost per mile is a pretty simple equation and using fleet management software is the easiest way to calculate it. Platforms like TransPlus have automated features that calculate your cost per mile, per fleet. However, there are some ways to calculate your truck costs on your own.

To find your trucking cost per mile, you will follow this formula: (Fixed Costs + Variable Costs) / Miles Driven = Your Cost Per Mile. There may be additional expenses and indirect costs that do not fit neatly into either category that may need to be included in the equation and added to your costs.

Example: ($50,000 + $150,000) / 120,000 miles = $1.67 per mile

Let’s break this down a bit more. Your fixed costs are the costs that do not change for each transport job. Some examples of fixed costs for the transportation industry include taxes, insurance premiums, and permits or licenses.

Examples of Fixed Costs for Cost Per Mile

• Truck and Equipment Payments
• Driver and Company Insurance Payments
• Licensing and Permits
• Taxes and Fees
• Depreciation of Equipment
• Additional Overhead Cost

Your variable costs will change on a job-by-job basis. They will also vary and fluctuate depending on how large your fleet is and how efficiently you are running your business. In general, the biggest variable expenses for fleets are fuel costs and maintenance fees. However, wages for your drivers, toll costs, and truck part replacement costs are also common variable costs to consider.

Examples of Variable Costs for Cost Per Mile

• Fuel Costs
• Maintenance and Repair Costs
• Tire Costs
• Driver Wages and Salaries
• Tolls and Weigh Station Fees
• Food and Per-Diem Costs for Drivers
• Detention and Loading Dock Fees
• Layover Fees

Other costs that may be considered either fixed or variable include tire maintenance, lease and purchase payments for the trucks themselves, truck driver benefits costs, etc.

Lastly, your miles driven will refer to the number of miles driven for a particular job.

It’s vital to have all this data and these metrics on hand to calculate your total cost per mile. Fleet management software can be a particularly helpful tool in calculating this number regularly, as well as gathering the necessary data to calculate it.

How To Reduce Your Cost Per Mile

There are a few ways companies can reduce their cost per mile for their fleets. To start, opting for fuel-efficient vehicles can help reduce the cost to regularly fuel your fleet, though the initial investment can be quite hefty and can take a while to be worth it. Managing and staying up to date with all of your fleet’s fuel receipts and connecting those inputs to your fleet management software can make a big difference.

Staying up to date with your vehicle preventative maintenance can cut down on costs related to regular maintenance and repairs. Using fleet management software can also help your management teams keep an eye on the routes that your truckers are taking to ensure the best possible mileage.

Strategies to Reduce Your Cost Per Mile

• Employ Fleet Management Software - Fleet management software and a Transportation Management System (TMS) can help optimize routes, improve efficiency, and reduce costs.
• Reduce Fuel Costs - Promote fuel-efficient operations for your fleet by investing in fuel-efficient equipment and employing practices to reduce fuel costs.
• Regular Maintenance - Perform regular maintenance checks on all fleet vehicles to ensure smooth operations and avoid downtime.
• Optimize Routes - Optimize your routes for fuel efficiency and travel time to reduce costs.
• Reduce Empty Miles - Empty miles are additional costs that can be mitigated by ensuring your trucks are always full and moving cargo.
• Retain Qualified Drivers - Qualified drivers can help your fleet remain efficient and reduce potential costs.

Trucking Cost Statistics

Trucking costs keep changing and vary by region, which makes it even more important to stay on top of your cost per mile data. According to the American Transportation Research Institute (ATRI), the average cost of operating a truck hit a record $2.336 per mile in 2025. That figure is a U.S. national industry average, so your own number will sit above or below it depending on your lanes, equipment, and region. To put it simply, if one of your trucks drove 75,000 miles at that average, it cost roughly $175,200 to keep that one truck in operation. It’s clear that each and every mile that you can reduce costs for will result in tangible savings for your business, which is why understanding your cost per mile and all of the factors that create it is so valuable.

The squeeze is coming from specific line items, and ATRI's 2026 Operational Costs of Trucking report, covering 2025 data, shows exactly which ones. Excluding fuel, costs rose 4.2% to $1.854 per mile. The steepest increases were tolls (up 13.2%), repair and maintenance (up 8.6%), driver benefits (up 6.6%), and tires (up 6.4%), while fuel and driver pay rose slower than inflation.
