Revenue Alone Tells You Nothing
A strong gross settlement can still leave you underwater once fixed costs and fuel are subtracted. Net profit, not revenue, is the number that decides whether the week actually paid.
Fixed Costs Get Spread Across the Week
Your truck payment, insurance, and other monthly fixed costs are divided by 4.33 weeks so they can be compared against a single week's revenue, the same time frame most settlement statements use.
Your Break-Even Rate Is Your Floor
Dividing total weekly cost by weekly miles gives you the exact rate per mile where you stop losing money. Any load priced below that number costs you to run.
Trucking Profit Calculator: Formula, Benchmarks, and a Worked Example
Weekly net profit is the number that tells an owner-operator whether the business is actually working, not just busy. Revenue can look strong on a settlement statement while fixed costs, fuel, and maintenance quietly eat most of it before a dollar reaches your pocket. This calculator converts your truck payment, insurance, and other fixed costs into a weekly figure, adds in fuel and maintenance scaled to the miles you actually ran, and shows what's left over. Once you know your break-even rate per mile, you can tell in seconds whether a load offer is worth taking or better left on the board.
What Weekly Net Profit Actually Measures
Weekly net profit is everything you brought in this week minus everything it cost to run the truck that week, fixed and variable combined. It's the single number that separates a business that's growing from one that's just staying busy. A truck can run every day of the week and still lose money if the rate per mile doesn't clear the true cost of fuel, maintenance, insurance, and the truck payment sitting behind it.
The Formula Behind This Calculator
This calculator starts by converting your monthly fixed costs (truck payment, insurance, and any other fixed monthly expense like permits, ELD, or phone service) into a weekly figure by dividing the total by 4.33, the average number of weeks in a month. Weekly variable cost is your combined fuel and maintenance cost per mile multiplied by the miles you actually drove that week. Add the two together for total weekly cost, then subtract that from your weekly revenue to get net profit.
Cost per mile, which doubles as your break-even rate, is total weekly cost divided by weekly miles. Net margin is net profit divided by weekly revenue, expressed as a percentage, and it's the fastest way to compare how efficiently two different weeks or two different trucks are running relative to what they brought in.
Realistic Industry Benchmarks
Most owner-operators aim for a net margin somewhere between 8% and 15% after every fixed and variable cost is accounted for, though the number swings with freight rates, fuel prices, and how new the truck's payment is. All-in cost per mile for a financed truck typically lands between $1.55 and $1.85, while a paid-off truck with lower insurance can run meaningfully below that. A margin under 5% for several weeks in a row is usually a sign the lane, the rate, or the truck's operating costs need a hard look.
A Worked Example
Using this calculator's own default numbers: $4,200 in weekly revenue, 2,200 weekly miles, a $1,800 monthly truck payment, $650 monthly insurance, $0.55 per mile in fuel, $0.18 per mile in maintenance, and $300 in other monthly fixed costs. Monthly fixed costs total $2,750, and dividing that by 4.33 gives a weekly fixed cost of $635.10.
Weekly variable cost is $0.73 per mile (fuel plus maintenance) multiplied by 2,200 miles, which comes to $1,606.00. Total weekly cost is $635.10 plus $1,606.00, or $2,241.10. Subtracting that from $4,200 in revenue leaves a net profit of $1,958.90 for the week, a net margin of about 46.6%. The break-even rate per mile works out to $1.02, meaning any load priced below roughly $1.02 a mile would be running at a loss once every cost is counted.
Why This Number Matters
Net profit is what actually funds truck replacement, emergency repairs, retirement savings, and everything else beyond just staying on the road. Tracking it weekly, rather than glancing at a settlement total, catches a slipping margin early enough to change lanes, renegotiate a rate, or trim a cost before a bad month becomes a bad quarter.
Common Mistakes With This Number
The most common mistake is judging a week by gross revenue alone and skipping the fixed-cost math entirely, which makes a high-mileage week look better than it actually was. The second is leaving maintenance out of the variable cost per mile, or underestimating it, which understates true cost and inflates the apparent margin until a big repair bill proves otherwise.

What Owner-Operators Say
“I used to look at my settlement total and feel fine. Once I ran the actual weekly numbers, I found two lanes that were barely breaking even.”
“Seeing the break-even rate per mile changed how I negotiate. I know exactly where the floor is before I say yes to anything.”
