A rate snapshot is worthless until you convert it into a number you will not go below. This week the market is handing independent dispatchers a specific problem: linehaul is drifting down a few cents at a time while diesel sits nearly $1.87 above where it was a year ago. That combination does not call for panic, but it does call for a floor you calculate rather than feel.
- Calculate a floor from carrier marginal cost plus fuel; quote linehaul and fuel separately; recalculate fuel math every Monday.
- Read load-to-truck ratios first to gauge leverage; hold flatbed floors hard and favor strong origins like Ohio River and California.
- Set one hard reject number per truck per week, write it down Monday, share with the carrier, and stick to it when markets soften.
The numbers on the table this week
Dry van spot linehaul averaged $2.21 per mile, down 1.6% or four cents from the prior week, according to DAT’s latest dry van report. Reefer held nearly flat at $2.63 per mile, off less than a cent, per DAT’s reefer report. Flatbed came in at $2.70 per mile, down two cents but still 35.1% above last year and 28.3% above the nine-year seasonal average of $2.10, per the flatbed report. All three figures are linehaul only — fuel is not in them.
On fuel, the national on-highway diesel average came in at $5.599 per gallon for the week of August 31, down about five cents week over week but roughly $1.87 higher than the $3.73 average a year earlier, per the EIA’s Gasoline and Diesel Fuel Update. That single line explains most of the margin complaints you are hearing from owner-operators right now.
Read the load-to-truck ratios before you read the rates
The ratios tell you how much leverage you actually have. Dry van sits at 9.98 loads per truck, easing from 10.05 a week earlier but nearly double the 5.77 of a year ago. Flatbed firmed to 36.11, from 33.31, against 20.44 last year. In both cases truck posts fell faster than load posts — capacity leaving, not freight surging.
That distinction matters when a broker tells you the market is soft. A falling rate on a tightening ratio is a seasonal give-back, not a collapse. You have more room to hold a number than the headline decline suggests, particularly on open deck.
With capacity pulling back faster than freight, the load-to-truck ratio firmed to 36.11, up from 33.31 a week earlier and well above 20.44 a year ago.

Build the floor: cost per mile plus fuel, then negotiate up
Start from the carrier’s real marginal cost, not a round number. ATRI’s Analysis of the Operational Costs of Trucking: 2026 Update put the industry-average cost to run a truck at $2.336 per mile in 2025 — the highest in the report’s history — with costs excluding fuel at $1.854 per mile. Add the fuel component separately: at $5.60 diesel and 6.5 mpg, fuel alone is about 86 cents per mile. At 7.0 mpg it is about 80 cents.
Put those two together and the message is blunt. A van load at the $2.21 national linehaul average, run by a carrier at ATRI’s average cost structure, is not a profitable load — it is a break-even load at best. Your floor has to be built from your carrier’s own numbers, and it usually needs to sit above the national average, not at it.
Then price against the linehaul benchmark, not the all-in offer. If a broker quotes $2.95 all-in on a 600-mile van run, back out the fuel surcharge before you compare it to $2.21. Dispatchers lose money by mentally comparing an all-in number to a linehaul benchmark and concluding the load pays better than it does.
- Recalculate the fuel line every Monday. A twenty-cent move in diesel is roughly three cents per mile at 6.5 mpg — real money over a 2,500-mile week.
- Quote linehaul and fuel separately. It makes your rate defensible and stops brokers from using a fat surcharge to disguise a thin linehaul.
- Chase the strong origins. Van rates lead from Ohio River at $2.53 and California at $2.51; Florida–South Georgia trails badly at $1.59. Do not let a truck sit in a weak origin waiting for a number that region is not paying.
- Hold your flatbed floor hardest. A 36:1 ratio is leverage. Open-deck is the one place this week where walking away from a cheap load costs you the least.
- Watch the mid-September forecast. DAT’s 35-day outlook puts dry van at $2.24 in mid-September within about eight cents. If you are quoting September commitments, that is your center point.
- Set a hard reject number per truck, per week. Write it down Monday. Deciding in the moment on a Friday afternoon is how floors erode.
The demand signal worth tracking into Q4
For anyone dispatching open deck, July single-family housing starts fell to a seasonally adjusted 808,000, down 9.9% from June and the third decline in four months. Building permits, though, rose 5.0% to a 1.443 million annual rate. Permits lead starts, so the read is a pause rather than a break — but construction-linked flatbed volume typically follows starts by one to two quarters. If your carriers run building materials, plan for a softer stretch in late Q4 and start prospecting industrial and machinery freight now rather than in November.
What to do with this before Friday
Take twenty minutes today and write one floor number per truck for the week, built from that carrier’s cost per mile plus this week’s fuel math, and share it with the carrier so you are defending the same number. Then check the diesel print again next Monday — a five-cent move is noise, but two more weeks of drift in either direction changes the arithmetic on every long haul you quote.
