Every load board sorts by rate per mile. Every broker quotes it. And it is the single most misleading number in trucking, because it leaves out the three things that decide whether you made money: the empty miles to get there, the days the load consumes, and what your truck costs to exist on those days. Here is how to turn a quoted rate into profit per day, with two loads that show why it matters.
What's missing from "rate per mile"
A quoted rate is almost always per loaded mile. It ignores:
- Deadhead. 150 empty miles to reach a 180-mile load means you drove 330 miles for 180 miles of pay.
- Time. A 925-mile run that takes two days and a 180-mile run that still takes a day, because of appointment windows and loading, are not comparable by the mile.
- Fixed cost. Your payments, insurance and permits cost the same on a day you gross $700 as on a day you gross $2,500. Every day on a load has to carry its share.
- Fees. Factoring, dispatch and quick-pay come off the top, as a percent of the gross.
The load math
You need five numbers about your own operation before you can judge any load. From a cost-per-mile model (or your last three months of bills): truck MPG, current fuel price, your variable cost per mile excluding fuel and driver (maintenance and tire reserves), your fixed cost per working day, and your driver pay model. The example truck below runs 6.5 MPG, fuel at $3.85, $0.16 per mile in reserves, $225 a day in fixed costs, driver pay of $0.60 on all miles, and a 3% factoring fee.
Load A: the long one
Chicago to Dallas. 925 loaded miles, 60 deadhead. Linehaul $2,150 plus a $0.42 per loaded mile fuel surcharge. Two days, $45 in tolls, factored at 3%.
| Line | $ | How |
|---|---|---|
| Gross revenue | 2,538.50 | 2,150 + (0.42 × 925) |
| Rate per loaded mile | 2.74 | 2,538.50 ÷ 925 |
| Fuel | 583.42 | 985 ÷ 6.5 × 3.85 |
| Variable reserve | 157.60 | 0.16 × 985 |
| Driver pay | 591.00 | 0.60 × 985 |
| Factoring | 76.16 | 3% × 2,538.50 |
| Fixed cost allocated | 450.00 | 2 days × 225 |
| Tolls | 45.00 | |
| Total cost | 1,903.18 | |
| Net profit | 635.32 | $317.66 per day · $0.64 per mile |
Load B: the one that looks better
A short hop with a great rate: 180 loaded miles for $650 plus the same $0.42 surcharge. But it's 150 miles of deadhead to get to it, and with the pickup window and the unload it takes the day.
| Line | $ | How |
|---|---|---|
| Gross revenue | 725.60 | 650 + (0.42 × 180) |
| Rate per loaded mile | 4.03 | 725.60 ÷ 180 — looks great on the board |
| Fuel | 195.46 | 330 ÷ 6.5 × 3.85 |
| Variable reserve | 52.80 | 0.16 × 330 |
| Driver pay | 198.00 | 0.60 × 330 |
| Factoring | 21.77 | 3% × 725.60 |
| Fixed cost allocated | 225.00 | 1 day × 225 |
| Total cost | 693.03 | |
| Net profit | 32.57 | $32.57 per day · $0.10 per mile |
Load B pays $1.29 a mile more than Load A and makes one-tenth the daily profit. The rate wasn't the problem. The 150 empty miles and the full day were. Revenue per all miles tells the story faster than rate per loaded mile: Load A is $2.58 across every mile driven; Load B is $2.20.
The three numbers to look at instead
- Revenue per all miles — gross ÷ (loaded + deadhead). Collapses the deadhead problem into one figure.
- Net profit per day — the number your bills are actually paid from. Decide what a day of your truck has to earn and measure every load against it.
- Breakeven linehaul — the gross at which net profit is zero. Everything above it is yours; everything below is a load you paid to haul. For Load B, breakeven gross is roughly $692, so $725.60 with the surcharge barely clears it.
Turning it into a counter-offer
Once you know your target profit per day, the minimum rate falls out of the same arithmetic. Say the target is $300 a day. Load B needs about $300 of net on a one-day load, which means about $276 more gross than it offers once factoring on the extra is counted. That's a specific number to put back to the broker ("I need $925 on the linehaul") instead of a feeling that it's a little light. If they can't get there, pass, and the next load on the board is one you've already run the math on.
A note on fuel surcharge
Treat the surcharge as revenue, not as a fuel rebate, and then cost fuel at the real pump price. Netting the two against each other hides the fact that a surcharge is usually paid per loaded mile while fuel burns on every mile, so a load with heavy deadhead can show a "covered" fuel bill that isn't. Keep both numbers visible; the math above does.
Two habits that make this automatic
Know your fixed cost per day. Monthly fixed bills divided by the days you actually work. For most single-truck operations it's a few hundred dollars a day, and it is the reason a one-day load has to be judged harder than a two-day load.
Log the loads you take. After a month you'll see which lanes and brokers actually produced profit per day, and it is rarely the ones with the highest quoted rate.
Run this on every load in ten seconds
The Load Profit Calculator takes the miles, rate, surcharge and days, pulls your costs from a Settings tab, and gives a TAKE IT / NEGOTIATE / PASS verdict against your target profit per day — plus the minimum linehaul that would hit it. $19, Excel and Google Sheets.
