Cost Per Mile Summary
This freight calculator provides estimates for US truck drivers. For final decisions involving pricing, taxes, or logistics planning, always consult with a certified professional.
What is trucking cost per mile (CPM)?
In the United States freight industry, trucking cost per mile (CPM) is the total financial expense required to operate a commercial truck for every single mile it travels. This metric includes both loaded miles (when you are hauling freight) and deadhead miles (when you are driving empty).
Knowing your true CPM is the most critical metric for owner-operators and fleet managers. It determines your break-even rate—the absolute minimum revenue per mile (RPM) you must earn from a broker or shipper just to cover your expenses. If your rate per mile is lower than your cost per mile, your trucking business is losing money on that load.
How to Calculate Trucking Cost Per Mile
Our free trucking calculator above does the heavy lifting, but understanding the formula behind it helps you manage your trucking expenses better. The basic formula is:
A Real US Trucker Example
Let’s look at a realistic scenario for an owner-operator driving a dry van across the Midwest:
- Total Miles Driven in a Month: 10,000 miles (includes 1,500 deadhead miles)
- Fixed Costs: $3,500 (Truck payment, commercial insurance, ELD, parking)
- Variable Costs: $6,000 (Diesel fuel, maintenance fund, tires, tolls)
- Total Business Expenses: $9,500
Calculation: $9,500 ÷ 10,000 miles = $0.95 per mile.
This driver’s baseline cost is 95 cents per mile. To generate a sustainable trucking profit, they must secure freight rates well above $0.95/mi to pay themselves a salary and grow their business.
Fixed vs. Variable Trucking Costs
To use the freight cost calculator accurately, you need to classify your trucking expenses into two main categories:
Fixed Costs
These are expenses that stay the same every month, regardless of whether your truck is parked or running 3,000 miles a week.
- Truck payments or lease
- Commercial truck insurance
- Health insurance
- Permits, plates, and IFTA software
- Monthly parking fees
Variable Costs
These expenses fluctuate based directly on how many miles you drive and the regions you operate in.
- Diesel fuel (your biggest expense)
- Preventative maintenance & repairs
- Tires and oil changes
- Tolls and scale fees
- Driver pay (if paying per mile)
Frequently Asked Questions
Should fixed costs be calculated monthly or weekly?
Either approach works, but consistency is the key to accurate truck accounting. If you enter monthly fixed costs into the calculator, you must enter your total miles driven for that exact same month.
Does cost per mile include deadhead (empty) miles?
Absolutely. Deadhead miles consume diesel and cause wear-and-tear without generating revenue. If you run 500 loaded miles and 100 empty miles to your next pickup, your CPM must be calculated using the full 600 miles.
