What Is Cost Per Mile (CPM)?
Cost per mile is the total amount it costs you to operate your truck for every mile driven. It includes both fixed costs (payments you make regardless of miles) and variable costs (expenses that change with how much you drive). Knowing your CPM is the single most important number for running a profitable trucking business.
Why Owner-Operators Need to Know Their CPM
If a broker offers you a load at $2.00/mile but your break-even cost is $1.85/mile, your actual profit margin is razor thin. By adding a standard 20% buffer, you get a suggested minimum billing rate that ensures you cover costs and take home real profit.
How to Lower Your CPM
Focus on reducing deadhead miles, negotiating better fuel discounts, keeping up with preventive maintenance to avoid expensive breakdowns, and maximizing the number of loaded miles you drive each month.
