For owner-operators and fleet managers, understanding the balance between expenses and income is the difference between thriving and going out of business. Two metrics rule the industry: Cost Per Mile (CPM) and Revenue Per Mile (RPM).
What is CPM?
Cost Per Mile represents your total overhead for every mile you travel, whether the truck is loaded or empty.
- Fuel & DEF
- Truck & Trailer Payments
- Insurance & Permits
- Maintenance & Tires
What is RPM?
Revenue Per Mile is the gross income you generate for every mile driven. It dictates your earning potential.
- Line Haul Rate
- Fuel Surcharge
- Accessorial Fees
- Detention Pay

Mastering Your Margins
Set Better Rates
If you don't know your CPM, you don't know your "break-even" point. Never accept a load that pays less than your CPM plus your desired profit margin. Knowing your numbers gives you negotiation power.
Factor in Deadhead
Always calculate metrics based on total miles (loaded + empty). If a load pays $3.00/mile but requires 200 miles of deadhead, your true RPM drops significantly.
Watch Your Variable Costs
Fuel is your biggest variable cost. Fluctuations in fuel prices will change your CPM weekly. Keep your calculations updated frequently using our online tools.
