Calculating your cost per mile is essential for determining whether you are charging enough for hauling a load. Knowing and understanding how to calculate cost per mile can help ensure you do not lose money. Truck drivers can go out of business if they don’t calculate their average cost per mile, which is why taking the time to do so is crucial.

To calculate your cost per mile for trucking, you will need to divide your total expenses by the total number of miles that were driven. Once you have your number, we can help you find ways to reduce your cost per mile and make your business more successful.

How to Calculate Trucking Cost Per Mile

Follow the steps below to determine how to calculate delivery cost per mile.

1. Calculate How Many Miles You Will Drive

To start, you may want to create a spreadsheet for tracking the factors involved in the calculation. The first factor in the formula for cost per mile is the number of miles you drive. This number includes both your compensated miles and deadhead miles, also known as the miles for which you are not compensated. Miles driven can vary greatly by owner-operator and could even vary from month to month for the same driver.

Choose a period over which you will track the number of miles driven. If you don’t already have a tracking system in place, you can use your odometer to calculate your mileage manually. You can also use software to track your mileage.

For example, you may decide to track your miles driven over the course of a month. At the start of the month, write down the number on your odometer and do the same at the end of the month. The difference is the number of miles you drove that month.

2. Determine Your Fixed Costs

On your tracking spreadsheet, include a column for your fixed costs. The fixed costs for your trucking company are the expenses that remain constant each month, no matter how many loads you transport or miles you drive.

Divide the total of any annual costs by 12 to get your monthly cost. Add it to the total of your other fixed costs. License plates, for example, are typically paid one time a year. If your yearly cost for license plates is $900, your cost per month is $75.

Your fixed costs may also include:

  • Permits
  • Salaries
  • Insurance
  • License plates
  • Truck payments
  • Accountant costs
  • Parking expenses
  • Cell phone payments
  • Equipment loan payments

Typically, your largest fixed costs will be your truck and insurance payments. Unless business operations change, you’ll add up your fixed costs only once to calculate your cost per mile.

3. Find Your Variable Costs

You’ll also need a column on your spreadsheet for your variable costs. These are the costs that vary each month, depending on how many loads you’ve transported and how many miles you’ve driven. The more miles you drive, the more your variable expenses increase. The fewer miles you drive, the lower your variable costs will be. Though these costs could be in a similar range from month to month, the exact cost isn’t the same.

Variable costs may include:

  • Fuel
  • Tolls
  • Tires
  • Food
  • Repairs
  • Utilities
  • Lodging
  • Unloading fees
  • Per-mile wages
  • Load board fees
  • Truck maintenance
  • Freight broker fees
  • Dispatching services

Typically, fuel, broker fees and driver wages are the largest variable costs. Depending on how drivers are paid, wages or salaries could fall under fixed or variable costs. Flat salaries fall under fixed costs, and per-mile wages fall under variable costs. A system for tracking these expenses is essential.

4. Calculate Your Trucking Cost Per Mile

Once you know miles driven and your total fixed and variable costs, you can calculate your cost per mile. Divide your total monthly costs by your total monthly miles to get your cost per mile for that month.

You can also calculate your cost per mile separately for your fixed and variable costs. To get your fixed costs per mile, divide your fixed costs by the miles. For example, if your fixed costs for the month are $2,000 and you drove 10,000 miles, your fixed cost per mile would be $0.20.

Perform the same calculation to get your variable costs per mile. For example, if your variable costs are $3,000, your cost per mile would be $0.30. Add these numbers together to get your total cost per mile, which would be $0.50. Use a trucking cost per mile calculator to help you calculate your cost per mile.

Having this number can help you understand how much you need to earn to cover your expenses and how much you need to earn to make a profit. In the above example, every cent you earn above $0.50 becomes a profit. If you charge $1.00 a mile, you’d make a profit of $0.50 per mile.
