Trucking cost per mile calculator: the number every rate has to clear
Enter a normal month: fixed bills, diesel price and fuel economy, per-mile costs and the miles you run. You get your cost per mile, split fixed and variable, a break-even rate, and a target rate with your margin.
Fixed costs per month
Variable costs
Your cost per mile
$1.27
- Fixed
- $0.48/mi ($4,760/mo)
- Fuel
- $0.59/mi
- Other variable
- $0.21/mi
- Target with 15% margin
- $1.50/mi
Break-even all-in rate: $1.27 per mile you drive. About $12,706 to run this month.
Total $12,710
Every load needs to clear $1.27 a mile across loaded and empty miles. Our dispatchers counter from your number, and you approve every load.
Get loads above my costThe trucking cost per mile is the one number that tells you whether a load makes money, and most carriers know it only roughly. This calculator builds it from a normal month of your own bills. Fixed costs spread over the miles you run; fuel and the other variable costs add on top. Drag the miles slider and watch the fixed share move along the curve: a slow month makes every mile more expensive.
How it is calculated
- Fixed cost per mile = fixed monthly costs ÷ miles per month (loaded and empty).
- Fuel cost per mile = diesel price per gallon ÷ miles per gallon.
- Other variable cost per mile = maintenance + tires + tolls + driver pay, each per mile.
- Cost per mile = fixed + fuel + other variable. This is your break-even all-in rate.
- Target rate = cost per mile ÷ (1 - margin). A 15% margin on a $1.27 cost means about $1.50.
The cost blocks under the results show one month in dollars, so you can see which costs are biggest before you decide what to cut.
A worked example
One owner-operator monthExample
- FIXED$4,760 ÷ 10,000 mi = $0.476/mi
- FUEL$3.80 ÷ 6.5 mpg = $0.585/mi
- OTHERMaintenance $0.15 + tires $0.04 + tolls $0.02 = $0.21/mi
- COST$1.271/mi, about $12,710 for the month
- TARGET$1.271 ÷ 0.85 = $1.495/mi with a 15% margin
These are EXAMPLE numbers for one tractor-trailer. Your insurance, payment and fuel economy will differ, sometimes a lot.
How to read the result
The split matters as much as the total. If fixed costs are a big share, miles are your lever: more loaded miles in the month lower every mile's cost. If fuel dominates, fuel economy, idle time and where you buy diesel are your levers. If repairs keep surprising you, put a real number in the maintenance line instead of hoping, because a cost you leave out still gets paid.
Where to find the numbers
- Fixed costs: your bank statements. Payments, insurance, plates, permits, IFTA filings, ELD and load board subscriptions, parking, phone.
- Fuel: your fuel card report. Divide gallons into miles for real economy, not the sticker number.
- Maintenance and tires: last year's repair and tire spending ÷ last year's miles.
- Miles: your ELD or IFTA records, loaded and empty together.
Industry surveys publish average costs per mile each year, and they're useful for spotting a line that's far off. Your own records are the only numbers that count for pricing your loads.
Lowering truck cost per mile
Some costs move only at renewal time, like insurance and the truck payment, so the everyday levers are miles, fuel and downtime:
- Fewer empty miles. Planning the reload before you deliver cuts deadhead, which costs the same per mile as loaded running and pays nothing.
- Less idling. Idle hours burn fuel without adding a mile.
- Steady speed. Fuel economy usually drops as highway speed climbs.
- Preventive maintenance. A scheduled service costs less than a roadside repair plus the lost days.
- Fewer idle days. A day parked still carries a full day of fixed costs.
Change one input at a time in the calculator to see which lever moves your number most.
From cost per mile to the rate you accept
Your cost per mile covers every mile; loads only pay for loaded miles. So compare the cost with a load's all-in rate, which spreads its pay over the deadhead too. The rate per mile calculator does that and gives a counter-offer from your target. Running a 26 ft box instead of a tractor? The box truck cost per mile calculator starts from box truck numbers and shows the loaded rate you need at different deadhead levels.
