Use one period and one fleet scope
Choose a month, quarter or another consistent period. Include the costs and miles for the same trucks and dates. Dividing a yearly insurance cost by one month’s miles produces a misleading number.
Add the costs of operating
For a cash-budget view, include fuel, driver compensation, truck or trailer payments, insurance, maintenance and tires, tolls and other operating overhead for that period. Include owner-driver compensation if you want the result to reflect the cost of your labor.
Use one consistent accounting approach. A cash payment view and a depreciation-based profit view are different; avoid counting the same ownership cost twice. Ask your accountant how to allocate irregular or prepaid costs for your intended analysis.
Count empty miles too
Total operating miles include loaded and empty movement. If you divide all operating costs only by paid miles, that is a different figure: the amount each paid mile would need to cover. Both can be useful if clearly labeled.
For a simple illustrative calculation—not a fleet benchmark—$10,000 in period costs divided by 5,000 total miles equals $2.00 per mile. If only 4,000 of those miles were loaded, the same costs require $2.50 per loaded mile before profit.
Use the result as a baseline
Compare periods using the same method. A single month can be distorted by a major repair or unusually low utilization. Review several periods and keep an eye on the inputs, not just the final number.
Cost per mile is not a recommended freight rate. A quote also needs to account for profit, empty repositioning, waiting time, route demands and costs not included in your model.
