Guide
To know what a load really costs you to haul, you have to split your expenses into two buckets: fixed costs and variable costs. Both go into your cost per mile — and missing either one gives you a number you can't trust.
Fixed costs stay roughly the same whether you drive 2,000 miles this month or 12,000. You owe them even when the truck is parked:
Because they're fixed, the more miles you run, the less each mile carries of them. That's why low-mileage months feel so expensive.
Variable costs rise and fall with the miles you drive:
Knowing both buckets tells you two different things. Your variable cost per mile is the floor — below it, every mile loses money before you've even covered the truck payment. Add your fixed costs spread across realistic miles, and you get your true break-even rate. That's the number that tells you whether a cheap backhaul is still worth taking.
