Trucking cost per mile calculator
Most owner-operators can quote their rate per mile but not their cost per mile. That's the number that decides whether a load makes money. Enter your real bills and miles — you'll get your cost per mile and the break-even rate every loaded mile has to pay.
How to figure your cost per mile
Two buckets, one division. Everything that bills you monthly no matter what — truck note, insurance, plates, permits, ELD, phone, accountant — goes in the fixed bucket. Divide that total by the miles you run in a month and you have your fixed cost per mile.
Everything that only costs you when the wheels turn goes in the variable bucket, priced per mile: fuel (pump price ÷ your MPG), maintenance and tires as a set-aside, tolls, scales, washes. Add the two buckets together and that's your total cost per mile.
Why empty miles change everything
Deadhead miles burn fuel and wear tires but nobody pays you for them. That means the paying miles have to carry them. This is why a load can show a fine rate per mile on the load board and still lose you money: the board quotes loaded miles, your costs run on all miles. The calculator above does that adjustment for you and reports break-even per loaded mile — the number worth comparing to a rate.
When your break-even is above market
It happens, and hauling more freight rarely fixes it. You have three real levers: cut a fixed bill (refinance, re-shop insurance, drop what you don't use), cut a variable cost (fuel buying, MPG, planned maintenance instead of roadside), or reduce deadhead so more of your miles pay. Holding out for a better rate is a fourth lever, but it only works if you have enough cash to wait — check your runway before you count on it.
Common questions
How do you calculate cost per mile for trucking?
Add up your fixed monthly costs (truck payment, insurance, permits, plates, overhead) and divide by the miles you run in a month — that's your fixed cost per mile. Then add your variable costs per mile: fuel (diesel price divided by MPG), maintenance and tires, tolls and everything else. Fixed cost per mile plus variable cost per mile is your total cost per mile.
What is the difference between fixed and variable costs?
Fixed costs hit whether the truck moves or not — the payment, insurance, plates, permits, your phone, your accountant. Variable costs only happen when you roll: fuel, tires, maintenance, tolls. Fixed costs per mile get worse in a slow month because the same bills spread over fewer miles.
Why do empty miles raise my cost per mile?
Deadhead miles cost you fuel and wear but earn nothing, so the paying miles have to cover them. If 15% of your miles are empty, your loaded miles need to pay roughly 18% more than your all-miles cost per mile just to break even.
What should I do if my break-even is above market rates?
You have three levers: cut a fixed cost (refinance, shop insurance, drop a subscription), cut a variable cost (fuel strategy, MPG, maintenance planning), or run more paying miles by reducing deadhead. Raising your rate only works if you can actually hold out for it, which depends on how much cash you have in reserve.
