The week looked good. Every truck moved, the board was full, drivers were happy enough. Then the numbers came in and the margin was thin again. A full board and a profitable week are two different things, and most dispatch scoreboards only measure the first one.
Five numbers separate them. None of them require a consultant, and all five can be pulled from loads you already ran. What they have in common is that they measure the work between the loads — the empty miles, the idle trucks, the paperwork sitting in a folder — which is exactly where carrier margin quietly leaks out.
1. Revenue per loaded mile
Total revenue tells you how hard you worked. Revenue per loaded mile tells you whether the work was worth doing. Take the linehaul on a load, divide by the loaded miles, and you have a number you can compare across lanes, customers, and brokers no matter how long the haul is.
- Look at it by customer and by lane, not just fleet-wide — one broker averaging $1.10 while your book averages $1.45 is a decision, not a data point.
- Good looks like a stable number that holds through a soft market. A number that swings 30% week to week means you are pricing on whoever calls first.
- The common mistake is including fuel surcharge in the numerator. It flatters the rate and hides which lanes are actually paying.
2. Deadhead percentage
Empty miles are the purest form of loss in trucking: you pay for the fuel, the hours, and the wear, and you bill nobody. Divide empty miles by total miles for the week. Anything in the low teens is normal; anything over 20% means your next load is being found too late.
The fix is rarely a better rate. It is finding the outbound load before the truck is empty, which means knowing where every truck will be tomorrow rather than where it is now.
You do not fix deadhead by negotiating harder. You fix it by booking earlier.
3. Loaded miles per truck per week
This is your utilization number, and it is the one that tells you whether growth means adding trucks or getting more out of the ones you have. A fleet running 2,200 loaded miles per truck per week with the same drivers and the same lanes as a fleet running 2,700 is leaving a truck's worth of revenue on the table for every eight it owns.
A quick rule of thumb
Divide the gap by your average loaded miles per load. That is how many loads a week you are missing — usually a dispatch and detention problem, not a sales problem.
4. Days from delivery to invoice
Every day between the wheels stopping and the invoice going out is a day of your own money financing someone else's freight. The number is easy to measure and uncomfortable to look at: average the days between the POD timestamp and the invoice date.
Carriers who sit at five or six days almost always find the delay in the same place — the paperwork arrived late, or arrived incomplete, and nobody noticed until billing went looking for it. Scanning the BOL at the dock instead of at the end of the week moves this number more than any collections process.
5. Accessorial capture rate
Detention, layover, extra stops, lumper fees. You earned them, and a meaningful share never makes it onto an invoice because nobody logged the arrival and departure time. Compare accessorials billed against accessorials that actually occurred for one month. The gap is money you already worked for.
This is the most winnable of the five. It requires no new freight, no new trucks, and no rate negotiation — only that the times get recorded where the work happens.
Bringing it together
Read together, these five explain the thin week. The board was full, but the trucks ran 19% empty, sat two days waiting on a reload, and three loads went out unbilled for detention nobody logged. That is a busy week and a thin month, and none of it shows up in total revenue.
Pick two to watch this week — deadhead percentage and days to invoice are the usual place to start. Measure them for a month before you try to move them. The number that surprises you is the one worth working on.
