How Do I Calculate My Break-Even Rate Per Mile?

What is a break-even rate per mile?

Your break-even rate per mile is the lowest gross rate that covers every cost a mile creates — truck payment, insurance, maintenance, fuel, and the percentage fees that come off the top of the rate before you ever see it. Under that number, the load costs you money to haul. Above it, margin begins. It is the single most useful number to know before you open a load board, because it turns “that rate feels okay” into one honest number you can compare against.

breakEvenRate = baseCPM ÷ (1 − commission%)

Two inputs, one division. The first input is your base cost per mile — the full stack of fixed, variable, and fuel costs spread across the miles you actually run. If you haven’t built that number yet, start with how do I calculate cost per mile for a semi truck? — everything on this page sits on top of it. The second input is the total of every fee charged as a percentage of the gross rate: dispatch, factoring, quick pay.

The whole trick of this formula — and the part most calculators and most napkins get wrong — is in that denominator. You divide by what’s left after the fees. You do not add the fees on top.

Why do you divide by (1 − commission %) instead of adding it?

Because the fee isn’t charged on your cost. It’s charged on the gross rate — the bigger number. Say your base cost is $1.80 per mile and your dispatcher and factoring company together take 10% of gross. The intuitive move is to add 10% to your cost: $1.80 × 1.10 = $1.98 per mile. Book at $1.98, and here is what actually happens: the 10% fee comes off the $1.98, not off the $1.80. You keep $1.98 × 0.90 = $1.782 — about two cents per mile under your cost, on a load you booked believing it broke even.

The correct question is: what gross rate R leaves me exactly $1.80 after the fee? That’s R × (1 − 0.10) = $1.80, which solves to R = $1.80 ÷ 0.90 = $2.00. Divide, don’t add. The gap looks small at low fee percentages and grows fast as they stack:

At a typical 6% (the worked example’s 3% dispatch + 3% factoring), the add method quietly underprices you by about $17 a week. At 15% — dispatch plus factoring plus a quick-pay discount — the error is roughly $119 a week, over $6,000 a year, hidden inside loads that looked like they broke even on the broker’s napkin. The error always lands on the same side: the add method never overprices you. It only ever leaves you short.

What goes into the base cost per mile?

The numerator of the break-even formula is your base CPM — three per-mile components added together:

baseCPM = fixedCPM (weeklyFixed ÷ weeklyMileGoal) + variableCPM + fuelCPM (price ÷ MPG)

Fixed costs — truck and trailer payments, insurance, permits, ELD, phone — don’t care how far you drive, so the fewer miles you run, the more each mile has to carry. Variable costs scale with the odometer. Fuel is usually the single largest slice; the mechanics of that line get their own page: how do I calculate fuel cost per mile for a truck?

For scale: ATRI’s 2025 update put the industry’s average total marginal cost at $2.260 per mile (2024 data) — a fleet number that includes driver wages, so it isn’t directly your base CPM. It’s a landmark, not a target. Your break-even is built from your real cost per mile, not an industry average — don’t be the average driver.

How do you price for a target margin instead of just breaking even?

Break-even is a floor, not a goal. Hauling at exactly break-even means the truck earned its keep and you earned nothing. The same gross-up logic extends to pricing for profit: decide the margin you want to keep from each gross dollar, and put it in the denominator next to the commission.

targetRate = baseCPM ÷ (1 − commission% − margin%)

Same $1.80 base CPM, 10% total commission, and say you want a 15% margin: $1.80 ÷ (1 − 0.10 − 0.15) = $1.80 ÷ 0.75 = $2.40 per mile. Check it: at $2.40 gross, the fees take $0.24, costs take $1.80, and $0.36 stays with you — exactly 15% of the gross. The naive approach here would be to break even and hope the margin shows up. This formula prices it in before you commit.

Notice what the two formulas give you together: a floor ($2.00) and a target ($2.40). The space between them is your negotiating room, in numbers instead of feelings.

How does the break-even floor work on a real load?

The floor is a per-mile number; a load is a bundle of loaded miles, deadhead miles, tolls, dock hours, and a flat rate. To use the floor, put the load in the same units: rate ÷ loaded miles gives rate per loaded mile, and every cost — including the deadhead miles you drive for free — gets counted against the load that caused them. The full chain lives in how do I calculate load profitability end to end?

A dated snapshot of why it matters. On July 10, 2026, a real $1,350 load from Erie, PA through Buffalo, NY to Boston, MA — 458 loaded plus 93 deadhead miles, $210 in tolls, 7.5 MPG, EIA diesel at $4.578/gal, 3% dispatch plus 3% factoring, $0.96/mi operating costs, 1.5 hours at the dock — grosses $2.95 per loaded mile. Napkin math (rate minus fuel and tolls) said +$804, roughly $64/hr estimated. The full math said +$194, about $15.50/hr estimated over 12.5 on-duty hours — a $610 gap between the two answers, with the load’s true cost landing at $2.52 per loaded mile. Both numbers cleared a $2.00 floor; only one of them told you what you actually keep.

Whether a rate above your floor is worth saying yes to is a different question — that comparison, with named industry benchmarks, is covered in what is a good rate per mile for owner-operators? LoadWizz computes this floor from your wizard profile — dispatch, factoring, and quick pay correctly grossed up as a share of gross. The math itself asks for nothing but a calculator and five honest inputs; more of it lives in the Learn library.
