Calculate cost per mile

Cost per mile (CPM) is calculated by dividing total operating expenses by the total miles driven, giving you a clear picture of how much each mile on the road truly costs. Knowing your CPM helps you set competitive rates, manage budgets effectively, and pinpoint opportunities to cut costs in your trucking operations.

Why Cost Per Mile Matters

What Is Cost Per Mile?

Cost per mile (CPM) represents the average expense of operating your truck for each mile it travels, encompassing both fixed and variable costs. Schneider Owner-Operators

Key Benefits of Tracking CPM

1. Accurate Pricing: By knowing your true cost per mile, you can quote rates that cover expenses and secure a profit margin.
2. Budget Forecasting: CPM data reveals spending patterns, enabling you to plan maintenance and reserve funds for high-cost periods.
3. Performance Benchmarking: Comparing CPM across vehicles or routes highlights inefficiencies and areas for improvement.

Gathering Your Numbers

Tracking Your Total Miles

Include both loaded miles (when carrying freight) and deadhead miles (when running empty) to capture the full distance your truck covers.

Listing Fixed Costs

Fixed costs remain the same regardless of how many miles you drive and typically include:

1. Truck payments and leases
2. Insurance premiums
3. Licenses, permits, and registration
4. Depreciation and financing charges

Accounting for Variable Costs

Variable costs vary with usage and often include:

1. Fuel and fuel surcharges
2. Maintenance and repairs
3. Tire replacements
4. Tolls and parking fees
5. Driver wages or owner-operator draw

Putting It All Together

Manual Calculation

Once you have your totals, apply the simple formula:

CPM = Total Expenses ÷ Total Miles Driven

For example, if your combined fixed and variable costs for the month were $12,000 and you drove 10,000 miles, your CPM would be $1.20.

Tips to Keep Your CPM Low

1. Optimize Routes: Use GPS-based planning to avoid unnecessary miles and reduce deadhead time.
2. Stay on Top of Maintenance: Preventive upkeep cuts down on costly breakdowns and extends tire life.
3. Improve Fuel Efficiency: Monitor MPG, adopt smooth driving habits, and consider aerodynamic upgrades.
4. Negotiate Smartly: Work with brokers and shippers to secure rates that cover your true CPM plus profit.

Conclusion

Regularly calculating and reviewing your CPM enables you to make data-driven decisions that boost profitability and keep your fleet competitive. Authorities recommend continuous monitoring to adapt quickly to market changes and expense fluctuations.
