Load Profitability Calculator

The trucking industry runs on speed. Brokers want an answer in two minutes. Load board postings disappear. There's always pressure to book and move. That pressure is why so many owner-operators accept loads that look fine on the surface and lose money in practice.

A real load analysis takes about 90 seconds. Here's the complete process.

Step 1: Get the Total Rate, Not the Per-Mile Rate

When a broker says "$2.80/mile for 520 miles," your first move is to compute the total: $1,456. That's the actual money moving from broker to you. Always work in total dollars — it's harder to obscure costs when you're comparing dollar amounts to dollar amounts.

Step 2: Calculate Your True Cost on This Specific Run

Your cost per mile (CPM) is an average across all loads. But each load has its own cost profile. A run on I-70 through the Rockies burns more fuel than a flat I-10 run at the same mileage. A run through New Jersey and New York adds $80–$120 in tolls a run through Kansas doesn't have. Add any route-specific costs before you analyze the margin.

A typical 520-mile dry van run might look like this: fuel at $4.10/gallon, 6.5 MPG = 80 gallons = $328 in fuel. Operating cost at $0.18/mile × 600 total miles (with 80 miles deadhead) = $108. No tolls. Total cost: $436. With $1,456 revenue, net profit is $1,020. Margin: 70%. TAKE.

But add 150 miles of deadhead (common when running to rural areas): total miles jump to 670. Operating cost rises to $120.60. Fuel for 670 miles at 6.5 MPG = 103 gallons = $422. Total cost: $543. Net profit: $913. Margin: 63%. Still a TAKE — but $107 less than you thought.

Step 3: Always Compare Against Your Monthly Minimum

The per-load analysis tells you if a load is good. But you also need to know if you're on track for the month. If your monthly fixed costs (truck payment, insurance, permits) are $4,200 and you need $6,000 to take home a decent wage, you need to average roughly $300 net profit per load day across your working days. A marginal load on a slow day may still be the right call if the alternative is parking.

Context matters. The calculator gives you the math — you apply the judgment.

Most owner-operators negotiate loads based on feel. They know $1.80/mile feels bad and $3.50/mile feels great, but they can't tell a broker exactly why a specific load at a specific rate doesn't work. That's a weak negotiating position, and brokers know how to exploit it.

When you know your minimum acceptable rate to the dollar, the negotiation changes completely.

How to Calculate Your Minimum Rate

The formula is simple: minimum acceptable rate = total costs × 1.25.

Total costs means fuel, operating expenses, tolls, and anything else this specific load requires you to spend. Multiply by 1.25 to get the revenue that produces a 25% margin. Anything below that number is not worth accepting.

For a load with $480 in total costs, your floor is $600 ($480 × 1.25). If the broker is at $560, you can say: "My costs on this run are $480. At $560, I'm making 17% margin — that's below what I need to stay in business. I need $610 to make this work." That's a specific, defensible number. Brokers respond to that differently than "I need more."

When the Math Says Walk Away

There are loads that simply don't pay enough for your cost structure, and no amount of negotiation will fix them. Recognizing these quickly is as valuable as closing a good load — every minute spent trying to rescue a bad load is a minute not spent finding a good one.

The rule is clean: if the broker's best offer is below your break-even rate (total costs ÷ total revenue = negative profit), decline and move on. You are not obligated to run freight at a loss because a broker has a shipper who needs coverage.

Common Mistakes That Inflate Your Apparent Floor

• Using average CPM instead of this-load CPM — if this load has extra tolls or unusual fuel stops, your actual cost is higher than your average
• Forgetting deadhead cost — 100 miles of deadhead at $1.68/mile (variable cost only) is $168 that comes directly out of the load rate with zero revenue to offset it
• Ignoring time cost — a 2-day load that pays $1,200 is worse than a 1-day load that pays $700, because time has value

Model every load through the calculator before you quote a rate. Your minimum acceptable rate is a function of actual costs, not a number you pick.

Most owner-operators evaluate loads based on the line haul rate and nothing else. That's leaving real money in the broker's pocket. Accessorial charges — the fees beyond the base rate — can add $50 to $400 to a single load's revenue when you know how to claim them.

Detention Pay

Detention is the most common accessorial, and the most commonly uncollected. The standard is: two hours of free time at pickup, two hours at delivery. After that, you charge detention. Industry rates run $50–$75/hour for standard freight, $75–$100/hour for reefer or specialized.

To collect detention, you need proof — usually a timestamp from the shipper's dock, a signed BOL with arrival and departure times, or photos with timestamps. If you arrive at 09:00 and don't get a door until 11:45, that's 45 minutes of detention. At $65/hour, that's $48.75 you're owed. Multiply that across 15 loads per month and you're looking at $700+ in uncollected revenue.

Set expectations with the broker before you arrive. When you book the load, confirm the detention rate and how to document it. Some brokers will tell you their shippers "never go over free time" — ignore this and document arrival every time anyway.

Lumper Fees

Lumpers are third-party unloaders at the consignee. If the consignee requires a lumper, you shouldn't be paying for it out of your load rate — the shipper or broker covers it. Get the lumper receipt and submit it with your invoice as a reimbursable expense. Lumper fees run $100–$300 depending on the load and location.

Before accepting a load to a warehouse known for requiring lumpers, confirm in writing that lumper fees are covered. If a broker won't commit to this, factor the potential lumper cost into your rate negotiation.

Other Accessorials Worth Tracking

• Layover pay: If you're held at a shipper overnight due to delays, you're owed layover compensation — typically $150–$250/day
• TONU (Truck Ordered Not Used): If you show up and the load is cancelled, you're owed a TONU fee — usually $100–$200
• Fuel surcharge: Some contracts include a fuel surcharge above a base diesel price — make sure yours is being calculated correctly
• Stop-off charges: Multi-stop loads should include a per-stop fee ($50–$75 per additional stop) beyond the first delivery

The load profitability calculation gets more accurate when you include all revenue, not just line haul. Add expected detention, confirmed lumper reimbursements, and any other accessorials into the total revenue field before analyzing the margin. A load that barely makes 20% margin on line haul alone might hit 28% once you account for an hour of detention pay at a notoriously slow shipper.
