Cost Per Mile Calculator

Your cost baseline on the left. Every load decision on the right.

1
Set your cost baseline (left panel)
Enter your weekly miles, monthly overhead (truck payment, insurance, permits), maintenance reserve, fuel MPG + price, and daily expenses. Do this once in the morning — your costs don't change load-to-load.
2
Set your profit margin goal
In the CPM output box, enter the profit margin % you want to earn on top of break-even. 20% is the default. This becomes your Target Rate — the number a load must beat to be worth taking.
3
Evaluate each load (right panel)
Enter the load miles, deadhead, gross revenue, days on load, and any deductions (dispatch, factoring, driver pay). Hit Calculate and read your verdict instantly.
4
Read your verdict
🟢 Healthy Margin — rate meets or beats your target
🟠 Marginal — profitable but below your target
🔴 High Pressure — below break-even, you're paying to work
