Trucking cost per mile calculator with a full cost breakdown

How it's calculated

• Fixed costs = everything you pay each month whether the truck runs or not, plus your own pay if you add it.
• Fuel = total miles ÷ MPG × diesel price.
• Variable costs = maintenance, tires, tolls and fees that grow with the miles you run.
• Cost per mile = (fixed + fuel + variable) ÷ total miles, loaded and empty.

Yearly bills such as plates, permits, IFTA and UCR go in as one twelfth a month. The diesel default is the weekly US average from EIA 453213; use what you actually pay. The cost lines start with EXAMPLE values so the chart has something to show. They aren't averages and they aren't a benchmark, so replace every one with your own numbers.

A worked example

EXAMPLE: an owner-operator with a financed tractor and trailer runs 9,000 miles a month at 6.5 MPG, with diesel at $6.20. Monthly costs are the starting values in the calculator.

So every mile this truck runs, loaded or empty, has to bring in at least $1.65 just to keep the business even. That's before the owner takes any pay. Add $5,000 a month as the owner's own pay and the floor rises to $2.20.

Miles change the answer more than you think

Fixed costs don't care how much you drive. Spread over fewer miles, they cost more per mile:

That's why a slow month hurts twice: less revenue, and a higher cost on every mile you did run. It's also why the miles input should be your real average, including empty miles, not the number you hope to hit.

Reading the result

Your break-even rate

Your truck cost per mile is the lowest all-in rate per mile you can accept and still stay even. Compare every offer to it on an all-in basis, after deadhead, not on the loaded rate the broker quotes. A load that pays less can still make sense now and then, but a week of them means the truck is losing money while it runs.

Which line to work on

The chart sorts your costs from largest to smallest. Fuel is usually on top, which makes MPG, idle time and route choice worth real money. Fixed lines tell you whether the truck is carrying too much debt for the miles it runs. Maintenance that swings month to month is a reason to average a few months before you trust the result.

With or without your pay

Run it both ways. Without your pay, the number is what keeps the truck alive. With it, the number is what keeps you working. The second one is the floor to quote from.

More than one truck

Run the calculator once per truck, not once for the fleet. Each truck has its own payment, miles and fuel economy, and an average hides the one that's losing money. Shared costs such as insurance, software and accounting can be split evenly across the trucks. If one truck's cost per mile sits well above the others, that's where to look first: debt, a maintenance problem, or a lane that runs too many empty miles.

Where to find your numbers

You likely have every figure already, spread across a few places:

• Bank and card statements for truck and trailer payments, phone, software and parking.
• Fuel card reports for gallons and price paid; divide miles by gallons for your real MPG.
• IFTA returns for total miles by quarter, the cleanest source for miles per month.
• Insurance declarations for the yearly premium, divided by 12.
• Shop invoices and your maintenance log for repairs and tires; average at least three months.
• Settlement statements for dispatch and factoring fees actually charged.

Common mistakes

• Dividing by loaded miles only. Empty miles cost the same to run, so they belong in the total.
• Leaving out yearly bills. Plates, permits and UCR feel like one-offs but they're part of every mile.
• Using your best month. A strong month with no repairs makes the truck look cheaper than it is.
• Forgetting fees. Factoring and dispatch percentages are real costs per mile once the loads are paid.
• Skipping your own pay. A truck that only breaks even is a job that pays nothing.

Cost per mile for different trucks

The same calculator works for any equipment we dispatch, from a 26 ft box truck to a heavy-haul setup. The lines change weight: a reefer adds unit fuel and maintenance, a flatbed adds tarps and straps, a hotshot often runs lower fixed costs on fewer miles. Add those costs to the closest line rather than leaving them out.

What to do with your number

Take it into every rate conversation. The load profitability calculator uses it to show what a single load nets, and the counter-offer target rate calculator turns it into a number to ask a broker for. When we dispatch for you, your floor is the first thing we write down, and offers below it don't reach your phone unless you've asked to see them.
