Trucking cost per mile calculator
Enter your monthly expenses to calculate your cost per mile (CPM) and the rate per mile you need to break even. Knowing your CPM is the foundation of every load pricing decision.

Understanding cost per mile
Cost per mile (CPM) is the total amount it costs to move your truck one mile, after accounting for both fixed and variable expenses. Knowing your CPM lets you look at any rate confirmation and know immediately whether that load covers your costs — and by how much.
Fixed vs. variable costs
Fixed costs are monthly bills that stay the same whether you drive 5,000 miles or 12,000 miles: truck payments, insurance, ELD subscriptions, permit fees. These costs per mile go down as you drive more miles, which is one reason why consistent volume matters for owner-operators.
Variable costs scale with miles: fuel is the biggest one, followed by maintenance, tires, and driver pay if you are not driving yourself. These costs per mile stay roughly the same regardless of monthly volume.
Why deadhead percentage matters
Deadhead miles (empty miles driven without a load) cost you fuel and maintenance but generate no revenue. When you calculate CPM based on total miles but price loads based on loaded miles only, the empty miles still need to be covered. A 15% deadhead rate means you need your loaded-mile rate to cover the cost of 1.18 miles for every loaded mile you actually bill.
This calculator spreads your total variable costs across all miles, then divides by loaded miles to give you a break-even rate that accurately reflects the cost of running empty miles as part of normal operations.
Factoring fees and effective rate
If you use invoice factoring, the fee reduces your effective rate. A $2.50/mile load with a 3% factoring fee nets you $2.425/mile after the fee. This calculator applies the factoring fee to the loaded-mile revenue to show you the actual rate per mile you retain.
What rate do you actually need?
Break-even is not a business — it means you covered expenses and earned nothing. Setting a target profit margin (15–25% is common for owner-operators) gives you the minimum rate you should accept to actually run a profitable operation. The calculator adds the profit margin on top of break-even to show the rate per loaded mile you need to hit your target.
How to use this in rate negotiations
When a broker offers a rate, the first question is not whether it is competitive with the market — it is whether it covers your costs. A rate that feels competitive because "other trucks are taking it" may still be a money-losing load for your specific cost structure. Know your number first. Every rate confirmation is a comparison against your CPM before it is a comparison against market rates.
Typical CPM ranges for owner-operators
Total CPM for over-the-road dry van owner-operators generally runs $1.40–$1.90/mile, though it varies significantly by truck age, insurance profile, miles driven, and equipment type. The main cost centers as a percentage of total expenses: fuel typically 35–45%, fixed costs (truck payment, insurance, permits) typically 30–40%, maintenance and tires typically 12–18%, and other variable costs the remainder. Operators running newer trucks with higher payments but lower maintenance costs often see a similar total CPM to those running older paid-off equipment with higher repair exposure — the cost mix shifts but the total is often comparable.
Short-haul operators (under 300 miles per load) typically have higher CPM because fixed costs spread across fewer total miles per month. Reefer operators have higher fuel cost from the refrigeration unit and higher insurance. These differences are why knowing your specific number matters — industry averages can be misleading for any given operation.
Frequently asked questions
- What is a typical cost per mile for a trucking owner-operator?
- Total CPM for an over-the-road dry van owner-operator typically runs $1.40–$1.90/mile. Fuel is usually the largest portion at $0.55–$0.65/mile; maintenance and tires add $0.15–$0.22/mile; insurance $0.10–$0.15/mile; truck payment $0.20–$0.35/mile. Your actual number depends on your specific expenses — use real numbers, not industry averages, when evaluating loads.
- What is the difference between cost per mile and break-even rate?
- CPM is total expenses ÷ total miles (including deadhead). Break-even rate is the minimum revenue per loaded mile you need to cover all expenses — it is higher than CPM because it accounts for empty miles that cost money but generate no revenue. A target rate adds your profit margin on top of break-even.
- How does deadhead percentage affect the rate I need?
- Every empty mile costs fuel and maintenance without generating revenue. At 15% deadhead, your 10,000 monthly miles include 1,500 empty ones. All those empty-mile costs must be recovered from the 8,500 loaded miles. Higher deadhead requires a higher rate per loaded mile to cover the same total cost base.
- How does factoring fee affect my effective rate?
- A 3% factoring fee on a $2,500 invoice costs $75 — you receive $2,425. Over 500 loaded miles, effective rate drops from $5.00 to $4.85/mile. This calculator builds the factoring cost into the break-even rate so you see the gross rate you need to quote, not just the net you want to keep.
