Quick Answer
Cost per mile (CPM) is your total operating expenses divided by total miles driven: add all fixed monthly costs (truck payment, insurance, permits) and variable costs (fuel, tires, maintenance, tolls), then divide by miles driven. Your CPM is your breakeven rate — any load paying below it loses money.
Key Takeaways
- CPM = total operating expenses ÷ total miles driven; it equals your breakeven rate.
- Separate fixed costs (per month, e.g. truck payment and insurance) from variable costs (per mile, e.g. fuel and tires) before dividing.
- Include every business expense and spread annual costs like inspections and registration across 12 months.
- Driving more miles per month lowers CPM by spreading fixed costs over more miles.
- Target loads paying at least 20% above your CPM, then add target profit per mile to set your minimum acceptable rate.

Why Cost Per Mile Matters
Cost per mile is the single most important number in your trucking business. It tells you the minimum rate you need to break even on every load. Without knowing your CPM, you're essentially guessing whether a load is profitable.
