Owner-operator profit per mile

The short answer

Profit per mile is what is left after everything — including your own pay, your tax reserve and your maintenance reserve — divided by the miles you ran.

Most carriers who think they are measuring profit are measuring revenue minus fuel. That gap is why a busy year can end with nothing in the account.

Slide reading "Profitable carriers know their numbers", listing cost per mile, break-even rate, insurance exposure, and which lanes actually make sense.
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 RATE YOU BOOKED PROFIT FUEL MAINT TIRES INS NOTE BREAK-EVEN VARIABLE — MOVES WITH THE MILE FIXED — YOU PAY IT PARKED RATE PER MILE IS NOT PROFIT PER MILE
One mile, by where the money goes FIG-03
Rate per mile is not profit per mile
Slide headed "Load A": $4.00 per mile, 300 miles, equals $1,200 revenue. "Sounds great… right?"
Slide headed "Meanwhile… Load B": $2.20 per mile times 650 miles equals $1,430 revenue. The truck keeps moving, no waiting at the dock, no sitting overnight with no freight, and the destination has a strong freight market so the next load is already lined up before unloading finishes. "Less per mile. More per day." That is the shift in thinking that separates struggling carriers from profitable ones.
Slide headed "The Bottom Line": Truck A earns $600 a day at $4.00 per mile over 300 miles with long delays and dead time; Truck B earns $1,430 a day at $2.20 per mile over 650 miles with no waiting and constant movement. Same road, same hours, very different results. "Rate per mile doesn't tell the whole story."
The subtraction

From gross to what you keep

Every line below comes out of the top number before anything is yours. The order is roughly the order people forget them in.

The illustration

Where a strong-looking month actually lands

Using the same figures as the cost-per-mile worked example — 10,000 loaded miles, 2,000 empty, $18,000 of total cost including a $5,000 owner's pay.

Gross revenue $21,000 10,000 loaded miles at $2.10
Total costs $18,000 Includes $5,000 own pay
Net profit $3,000 On top of the owner's pay
Profit per mile $0.25 $3,000 ÷ 12,000 total miles

Twenty-five cents a mile of genuine profit, on top of paying yourself $5,000. That is a healthy month. Take the owner's pay out of the cost column and "profit" becomes $8,000 — a number that looks better and tells you nothing.

Where the money leaks
Slide reading "One — Recourse or Nonrecourse", explaining that with recourse factoring you are responsible for unpaid invoices, while non-recourse means the factoring company assumes the risk.
Slide reading "Two — Contract Length": short term versus long term, early termination, buyout options and associated penalties.
Slide reading "Three — Watch For Fees": transparency is key, request a clear breakdown of all fees including hidden costs, and negotiate the total cost.

Factoring is a cost line most carriers never compare.

The three reserves that separate a business from a hustle

  • Tax. Moved to a separate account the week the money arrives. The percentage is between you and your accountant; the timing is not negotiable.
  • Maintenance. Reserved per mile as though it were a bill. Breakdowns are scheduled events with unknown dates.
  • Slow season. Freight is cyclical. The carriers who survive a soft market are the ones who funded it during a good one.

A carrier without these reserves is not choosing to take cheap freight when the turbo goes — they are forced to, which is a much worse position and it compounds.

Where profit per mile sits among the numbers

It is the last of the five, and it depends on all four before 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

I don’t believe in telling business owners, “You need this policy,” without explaining WHY. I want you to understand the risk first. Then, we can talk about the solution.

Her working method
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

Know the number, then protect it

Dispatch that books against your break-even instead of against the board is how the profit line stays positive in a soft market.

Cutting what you can control
Slide headed "Ten ways to mitigate fuel expenses": reduce load weight, reduce deadhead, reduce idle time, preventative maintenance, tire pressure, fuel additives, efficient trip planning, consider weather conditions, monitor speed, rate per mile.
"Did you know?" slide: "Idling a semi truck burns about a gallon of diesel per hour, which could cost you thousands over the course of a year." Attributed to Shay Denise, CEO.
Quick tip slide: "Set an average daily rate. Whether you're a carrier or dispatcher, have an average amount per day that you want your truck or trucks to make, and only secure loads that fall in line with that."
Where weekly revenue crosses weekly cost Two lines plotted against miles run in a week. A cost line starts above zero, because fixed costs such as the truck payment and insurance are owed before any mile is driven, and rises gently with fuel and maintenance. A revenue line starts at zero and rises more steeply. The point where they cross is the break-even mile. The area before the crossing is marked as loss and the area after it as profit. No values are shown on either axis, because they differ for every operation. BREAK-EVEN LOSS PROFIT COST REVENUE FIXED COSTS — OWED AT ZERO MILES MILES RUN THIS WEEK →

FAQ

Profit per mile questions

What is profit per mile?

What is left after every cost of running the business, divided by the miles you ran. Not revenue per mile, and not revenue minus fuel. If your tax reserve, your maintenance reserve and your own pay are not in the calculation, the number you are looking at is not profit.

Why does my gross look great and my bank account not?

Because gross is the first number in a long subtraction. Fuel, the truck payment, insurance, maintenance, tires, permits, factoring fees, dispatch, tolls, parking, accounting and tax all come out before anything reaches you. A carrier grossing well can be losing money and stay busy the whole time — busy is not the same as profitable.

Should I count my own pay as a cost or as profit?

As a cost. Pay yourself a defined amount as a fixed expense, then measure profit on top of that. If your pay is whatever happens to be left, you have no way of telling a good month from a bad one, and no way of knowing whether the business would survive hiring a driver to replace you.

How much should I reserve for tax?

Set a percentage and move it out of the operating account the week you get paid, not at quarter end. The exact percentage depends on your entity and your situation and is a question for your accountant — but the discipline of separating it immediately is what prevents the January problem, whatever the number is.

What about maintenance?

Reserve for it per mile, every settlement, as though it were a bill. Major repairs are not surprises, they are scheduled events with unknown dates. A carrier without a maintenance reserve is one turbo away from taking bad freight to cover a repair, which is how a mechanical problem becomes a business problem.

Is profit per mile the right metric?

It is the right accounting metric and the wrong booking metric. Use profit per mile to judge the business over a month. Use revenue per day to judge an individual load, because a load consumes days rather than miles.
