Cost Per Mile
Cost per mile (CPM) is the total operating cost divided by total miles driven in a given period. It includes both fixed costs (insurance, truck payment) and variable costs (fuel, maintenance) per mile.
In Depth
Knowing your CPM is fundamental to trucking business management. Industry averages range from $1.40–$2.20/mile depending on equipment, fuel prices, and operating region. Most owner-operators underestimate CPM by forgetting variable costs like tires, repairs, and depreciation.
Fixed CPM decreases as you drive more miles per month — your truck payment is the same whether you drive 8,000 or 12,000 miles. Variable CPM stays roughly constant per mile. This is why maximizing loaded miles per month is critical to profitability.
Usage Example
Example: 'After calculating all expenses, my true cost per mile is $1.87. I need to average at least $2.10/mile to earn a reasonable income.'

Rate Per Mile
Rate per mile (RPM) is the gross revenue a carrier earns per mile driven. It is calculated by dividing the total load rate by total miles (loaded + deadhead) and is the most common profitability metric in trucking.
Operating Ratio
Operating ratio is total operating expenses divided by gross revenue, expressed as a percentage. A ratio of 85% means $0.85 of every dollar earned goes to expenses, leaving a 15% profit margin.
Break-Even Rate
The break-even rate is the minimum rate per mile a carrier must charge to cover all operating costs without making a profit or loss. Any rate above break-even generates net income.
