Trucking cost per mile calculator

The short answer

Cost per mile is everything your business spends in a period, divided by every mile you ran in that period — including the empty ones.

Enter your numbers below and you will get your cost per mile, your fixed and variable split, and the loaded rate you need to break even once deadhead is accounted for. Nothing is stored and no email is required.

Slide 02, "Know Cost Per Mile": knowing operating expenses is essential for knowing what needs to be made to turn a profit and to justify a request for a higher rate.
How one mile of revenue is consumed by cost A horizontal stacked bar showing a single mile of running cost split into fuel, maintenance, insurance, truck note and other fixed costs. The end of the bar is marked as the break-even point. A separate line above shows a booked rate, and the gap between break-even and rate is labeled as the only part that is profit. No dollar figures are shown, because the figures differ for every operation.

The five numbers
Slide headed "5 Financial Numbers Every Carrier Must Know": cost per mile, break-even rate, weekly fixed expenses, tax reserve percentage, and net profit after everything.
Slide headed "Know Your Numbers": understanding essential metrics is crucial for trucking success and financial stability. Cost per mile, insurance structure, compliance timing, cash flow gaps.
Definition slide headed "RPM & CPM". Rate per mile: the rate of a load divided by the total number of miles from the origin, deadhead possibly included, to the destination. Cost per mile: the sum of the monthly expenses divided by the number of miles driven for the month. Knowing operating expenses, including variable ones such as fuel, repairs, meals and maintenance, helps in knowing what to charge and accept to see a profit, and where to cut costs if necessary.
Fixed costs — happen whether you move or not

Variable costs — happen per mile

Use the same period for both sides. Weekly costs with weekly miles, or monthly with monthly — never one of each.

Cost per mile — All costs ÷ all miles
Break-even loaded rate — What loaded miles must earn to cover deadhead
Fixed per mile — Falls as you run more miles
Variable per mile — Roughly constant per mile

How to do it on paper

  1. Pick a period and stick to it. A month is usually the most honest, because it smooths out a good week and a bad one.
  2. Add every fixed cost for that period. Truck note, insurance, permits, plates, ELD, accounting, phone — and your own pay. If it happens whether or not the wheels turn, it is fixed.
  3. Add every variable cost for that period. Fuel, DEF, tires, maintenance, tolls, scales, parking.
  4. Add all the miles for that period — loaded and empty. This is the step people skip, and skipping it is what makes an unprofitable operation look fine.
  5. Divide total cost by total miles. That is your cost per mile.

A $4.00/mile load isn't always better than a $2.20/mile load.

Why break-even is higher than cost per mile

Your costs are spread across every mile you run. Your revenue is only earned on the loaded ones. So the rate you charge on loaded miles has to carry the empty ones as well.

If a quarter of your miles are deadhead, every loaded mile is carrying about a third more cost than your headline cost per mile suggests. That is the gap between "this rate covers my costs" and "this rate actually pays me", and it is why the calculator above asks for the two mileage figures separately.

Three ways the arithmetic goes wrong
Slide numbered 1, "Mixing Time Frames": adding weekly miles but comparing them against monthly expenses. Quick fix — always match time frames.
Slide numbered 2, "Forgetting Fixed Costs": many truckers count fuel, tolls and repairs but skip insurance, permits, truck payments or dispatcher and broker fees.
Slide numbered 3, "Not Separating Business and Personal": mixing personal expenses with trucking costs muddies the water. Quick fix — keep a separate account and card.

The five numbers this feeds into

Cost per mile is the first of five. The others only make sense once you have it.

  1. 01 Cost per mile
  2. 02 Break-even rate
  3. 03 Weekly fixed expenses
  4. 04 Tax reserve percentage
  5. 05 True net profit
Her working method
Checklist slide headed "The Metrics I Care About": revenue per day, weekly revenue, deadhead, profit margin, fuel cost, reload market, time utilization.
Slide 03, "Know Market Rates": the going rate for a specific lane and commodity can be used as a benchmark for negotiating.
Slide 01, "Know Your Lanes": being able to estimate transit times and express that to brokers ensures timely deliveries and proficiency.

Now use it on an actual load

Knowing your cost per mile is what turns "that rate sounds good" into a decision. If you want someone applying it to your week, that is the job.

Three mistakes that break owner-operator cost arithmetic Three numbered cards. One: mixing time frames — adding weekly miles but comparing them against monthly expenses; the fix is to always match the time frames. Two: forgetting fixed costs — counting fuel, tolls and repairs but skipping insurance, permits, truck payments and dispatcher or broker fees; the fix is to track both fixed and variable costs. Three: not separating business and personal — mixing personal spending with trucking costs; the fix is a separate account and card for the business. 1 MIXING TIME FRAMES Weekly miles set against monthly bills. QUICK FIX MATCH THE PERIODS 2 FORGETTING FIXED COSTS Fuel and repairs counted. Insurance, permits and the note skipped. QUICK FIX FIXED + VARIABLE 3 BUSINESS MIXED WITH PERSONAL Grocery runs and truck costs in the same account. QUICK FIX SPLIT THE ACCOUNTS ALL THREE PRODUCE A COST PER MILE THAT LOOKS FINE AND ISN’T

FAQ

Cost per mile questions

What is cost per mile?

Every dollar your business spends in a period, divided by every mile you ran in that period — loaded and empty. It is the number that tells you whether a rate is profitable. Anything above it contributes; anything below it costs you money to haul.

Do I include deadhead miles?

Yes. This is the mistake that makes people think they are more profitable than they are. Empty miles cost fuel, tires and hours, and they earn nothing. If you divide costs by loaded miles only, your cost per mile comes out artificially low and every rate looks better than it is.

Do I include my own pay?

Yes, and treat it as a fixed cost. If you do not pay yourself in the calculation, you are not running a business, you are running a hobby that happens to move freight. Put in what you actually need to take home.

Fixed or variable — which is which?

Fixed costs happen whether the truck moves or not: truck note, insurance, permits, ELD subscription, accounting, your own pay. Variable costs happen per mile: fuel, tires, maintenance, tolls, def. The distinction matters because fixed costs per mile fall as you run more miles, which is why a slow month is far more expensive than it feels.

What period should I use?

Match the timeframes. Weekly miles against weekly expenses, or monthly against monthly. Mixing them — adding up a week of miles and comparing it to a month of expenses — is one of the most common arithmetic mistakes in trucking, and it makes your cost per mile look about a quarter of what it really is.

Is my break-even rate the same as my cost per mile?

Close, but not identical. Cost per mile is what running costs you. Break-even rate is what you must charge to cover it — and because part of your mileage is deadhead, the rate on the loaded miles has to carry the empty ones too. If a quarter of your miles are empty, your loaded rate needs to be meaningfully above your cost per mile just to break even.

Do you store what I enter?

No. The calculator runs entirely in your browser. Nothing is sent anywhere, nothing is saved, and there is no email gate.
