Per-trip profitability is the profit on a single load — revenue minus all variable costs to move it. In the soft 2026 freight market, average margins hide loads that lose money, and only trip-level math catches them. TruckerPro's free trip profit calculator turns a 30-second input into a profit dollar amount and margin percentage you can use during a quoting call.
TL;DR
- Per-trip profit = revenue − variable costs (fuel, tolls, driver pay, factoring, deadhead).
- Healthy margin per trip in 2026: 15–25% dry van, 20–30% reefer, 25–40% specialized.
- Reject the load if contribution margin is negative or depends on an unbooked backhaul.
- Average margin lies. A 12% net average can include 30% loss-making loads.

What is per-trip profitability?
Per-trip profitability is the profit a single load generates — total revenue minus the variable costs needed to move that one load. It's a different number from the carrier's overall margin, and it's the number that should drive every accept-or-reject decision on a spot load.
The terminology gets used loosely. "Trip profit," "load profit," "lane profitability," and "contribution margin per trip" all describe roughly the same calculation. The technically correct term is contribution margin — what the load contributes toward fixed costs and profit, after the variable costs to move it. We'll use "trip profit" and "contribution margin" interchangeably here.
What it is not: it is not net profit. A load with a $200 contribution margin doesn't put $200 in your bank account — it contributes $200 toward covering the truck payment, insurance, dispatcher salary, office rent, and other fixed costs. Net profit appears only after fixed costs are covered.
But here's the thing: fixed costs are fixed. They don't change whether the truck runs 8,000 miles in a month or 12,000. The only number that changes with each accept-or-reject decision is contribution margin. That's why it's the right number for load-by-load decisions.
How do you calculate trip profit?
The full formula:
Trip profit = Linehaul revenue + Accessorials − (Fuel + Tolls + Driver pay + Factoring fee + Deadhead cost + Per-load broker/board fees)
Walking through each line:
- Linehaul revenue. The base rate the broker or shipper agrees to pay for moving the freight. Read the rate confirmation carefully — the per-mile number on a load board may not match the rate con.
- Accessorials. Anything billable on top of linehaul: fuel surcharge, detention, layover, lumper, multi-stop pay, hazmat. The accessorial charges guide covers what's standard.
- Fuel. Total miles ÷ truck mpg × diesel price. A 6.5 mpg truck running 800 miles at $4.20/gal: 800 ÷ 6.5 × $4.20 = $516.
- Tolls. Estimated using the free toll calculator — zero on Western lanes, $30–$200+ on Northeast lanes.
- Driver pay. If paid per loaded mile (typical), it's loaded miles × pay rate. If salaried, allocate the trip's portion of the daily salary.
- Factoring fee. If you factor invoices, the fee comes off the top — typically 1.5–3% of invoice value for recourse factoring.
- Deadhead cost. Empty miles to reposition for this load × per-mile deadhead cost (~$1.20). If the truck would be empty regardless, you can argue this is sunk cost; for a clean per-trip view, include it.
- Per-load fees. Some carriers pay $5–$15/load to a load board (major load boards) or $10–$25 to dispatcher services on a per-load basis.
The result, divided by linehaul revenue, gives the contribution margin percentage.
A worked example
A spot-market load: Newark, NJ to Cleveland, OH. Broker offers $1,150 linehaul, no accessorials. The truck is currently in Newark unloaded — no deadhead repositioning needed.
| Line item | Amount |
|---|---|
| Linehaul revenue | $1,150.00 |
| Accessorials | $0.00 |
| Gross revenue | $1,150.00 |
| Fuel: 460 mi ÷ 6.5 mpg × $4.20/gal | −$297.23 |
| Tolls: NJ Turnpike + PA Turnpike + IN Toll Road (5-axle) | −$165.00 |
| Driver pay: 460 loaded mi × $0.45 | −$207.00 |
| Factoring fee: 2% × $1,150 | −$23.00 |
| Deadhead repositioning: 0 mi | $0.00 |
| Total variable cost | −$692.23 |
| Contribution margin (dollars) | $457.77 |
| Contribution margin (%) | 39.8% |
This is a good load. 39.8% contribution margin clears every benchmark for dry van; the truck contributes $458 toward fixed costs and profit on this single trip.
Now flip one variable: imagine the truck is currently in Albany, requiring 150 miles of deadhead to get to Newark for this load. Add $180 deadhead cost (150 × $1.20). New contribution margin: $277.77 / $1,150 = 24.2%. Still acceptable, but materially different.
Now flip another variable: imagine the broker offered $850 instead of $1,150 (which is closer to current Newark–Cleveland soft-market spot rates).
| Line item | Amount |
|---|---|
| Gross revenue | $850.00 |
| Total variable cost (with 150 mi deadhead) | −$872.23 |
| Contribution margin | −$22.23 |
Now the load loses money. Even before fixed costs, the truck is moving $22 backward by accepting this load. Reject.
The same broker may pitch this $850 load three times in a busy day — and a dispatcher running on instinct may take it. A dispatcher running trip profit math on every quote sees the negative number and walks.
What is a good profit margin per trip in 2026?
Healthy contribution margins by equipment type in the 2026 market:
| Equipment | Healthy contribution margin | Floor (don't go below) |
|---|---|---|
| Dry van | 15–25% | 8% |
| Reefer | 20–30% | 12% |
| Flatbed | 18–28% | 10% |
| Specialized (heavy haul, oversize) | 25–40% | 18% |
| LTL / regional | 18–25% | 12% |
The "floor" isn't a hard rule — strategic loads (positioning for a high-margin backhaul, dedicated-lane test runs, customer-relationship freight) can be acceptable below it. But the floor should be a flag for review, not the average.
A carrier whose average contribution margin sits at the floor is in trouble. A carrier whose average sits in the healthy range can absorb the occasional below-floor load without breaking. The carrier profit margin benchmarks guide digs into the broader benchmark landscape.
When should you reject a load?
Reject when any of these are true:
- Negative contribution margin. The load loses money before fixed costs. No strategic justification matches "I'd like to lose money on purpose."
- Backhaul-dependent profitability. If the only profitable scenario assumes a return load you haven't booked, the load is one phantom-backhaul away from being a 100% deadhead loss. Book the backhaul first, then accept.
- HOS conflict. A load that requires the driver to violate hours-of-service rules to deliver on time is rejected on principle — and on safety. No spot rate justifies a violation.
- Equipment mismatch. A load that requires equipment you don't have (pallet jack, straps, tarps, hazmat placards). Sourcing the equipment last-minute eats margin.
- Customer red flags. Slow-pay broker reputation, missing rate confirmation details, vague accessorial language. The trip-profit math is irrelevant if you don't get paid.
For (1) and (2), the calculator is the tool. For (3)–(5), it's professional judgment.
Why average monthly margin hides losses
A carrier looks at the monthly P&L and sees 12% net margin — fine. The carrier accepts that as "we're doing okay" and moves on.
What the average hides: a typical for-hire carrier's load distribution is something like:
- Top 20% of loads: 30%+ contribution margin
- Middle 50%: 15–25% contribution margin
- Bottom 30%: under 10%, with the bottom 10% running negative
The 12% average comes from blending those buckets. The carrier is leaving real money on the table by running the bottom-30% loads — those loads consume capacity (driver hours, truck hours, dispatch attention) that could otherwise be used for middle or top loads.
The lever: trip-level visibility. Once a carrier ranks last month's loads by contribution margin and sees the bottom 30% explicitly, the conversation changes. "Why are we running these?" is the right question. Sometimes the answer is "we shouldn't be" — and cutting them, plus redeploying capacity to better lanes, can lift the carrier's monthly average from 12% to 16% with no other changes.
The same logic shows up in dispatch KPIs: visibility forces discipline.
How to use the free trip-profit calculator
The free trip profit calculator is built for two workflows:
Workflow 1: real-time quoting. A broker calls. While they're talking, plug in the rate, miles, fuel mpg, and toll estimate. The calculator returns contribution margin in dollars and percent. Decision in 20 seconds.
Workflow 2: end-of-week review. Run last week's loads through the calculator, build a quick spreadsheet of contribution margin per load, sort descending, and look at the bottom 5. Are they strategic or are they leaks? Most weeks there's at least one leak.
Inputs the calculator accepts:
- Linehaul revenue
- Accessorials (detention, layover, fuel surcharge)
- Total miles (loaded + deadhead)
- Truck mpg + diesel price (or accept the default)
- Driver pay rate per mile
- Factoring percentage (or 0% if not factoring)
- Toll estimate (use the toll calculator and paste the result)
Outputs:
- Total variable cost
- Contribution margin (dollars)
- Contribution margin (%)
- Cost per loaded mile (your effective CPM for this trip)
It's free, browser-only, no account. Use it during quoting calls or as a pre-acceptance check on every load over $1,500.
Frequently Asked Questions
What is per-trip profitability?
Per-trip profitability is the profit (or loss) on a single load — total revenue minus all variable costs to move that load. Unlike monthly average margin, it tells you whether each individual load was worth running. In a soft 2026 market, knowing your trip-level number is what stops you from filling the truck with money-losing freight.
How do you calculate trip profit?
Take linehaul revenue plus accessorials (detention, layover, fuel surcharge), then subtract variable costs: fuel, tolls, driver pay (if per mile), factoring fee, deadhead repositioning cost, and any per-load broker or load-board fees. The result is contribution margin — what the load contributed toward fixed costs and profit.
What is a good profit margin per trip in 2026?
In the current freight market, a healthy contribution margin per trip is 15–25% on linehaul revenue for dry van, 20–30% for reefer, and 25–40% for specialized. If a load comes in under 10%, scrutinize: it may be a strategic move (positioning for a backhaul) but it should not be your average.
When should you reject a load?
Reject when contribution margin is negative — the load loses money even before fixed costs. Also reject when the only profitable scenario depends on a backhaul you have not lined up. Phantom backhauls turn "thin but acceptable" loads into 100% deadhead loss-makers.
Why does average monthly margin hide losses?
Averages can be carried by a few high-margin loads while the bottom 20–30% of loads run at a loss. A carrier averaging 12% net could have one third of loads losing money, one third breakeven, and one third highly profitable. Trip-level visibility lets you cut the losers without giving up the winners.
How does the free trip-profit calculator help?
Plug in revenue and your variable costs (the calculator pre-fills typical fuel + driver-pay numbers based on miles and rate inputs) and get a profit dollar amount and margin percentage in seconds. Useful for spot-rate decisions during a quoting call and for a 5-minute end-of-week review of which loads carried their weight.
