The Shipper's Manifest reported that the published long-distance LTL price index rose 4.25 percent in September to 319.869, a record, while weekly diesel averaged 15.17 percent above August. Its argument, in LTL Prices Hit a Record as September Diesel Averaged 15 Percent Above August: What a Lane Rate Is Built From, is that a public series explains direction, not your number, and the risk is mistaking a billing error for market movement. Here is what that looks like on one shipping desk.
The operation in this walkthrough is illustrative, built to reflect a typical small or mid-sized manufacturer, distributor or warehouse: Pennhollow Blower Works, a 97-person maker of industrial ventilation blowers and louvers in a 61,000 square foot central Ohio plant, running about 70 outbound LTL shipments a month. Its customer, Halvern Mechanical Supply, is invented too, and every figure below is illustrative. The workflow and the arithmetic are real. The companies are not.
The line
Most months, Pennhollow ships the same load to Halvern, a distributor outside Macon, Georgia, on its own carrier account at its own negotiated discount. The desk requotes it in October and the number is higher than the one anyone remembers. The September headlines are fresh, so the conclusion arrives fast: the incumbent carrier raised rates, and someone starts looking at moving the lane. Nobody has the August quote in front of them, and nobody has asked whether the shipment changed.
What did not move
The shipment is six pallets, each 48 by 40 by 60 inches, and 3,900 pounds in total.
- One pallet: 48 x 40 x 60 = 115,200 cubic inches, divided by 1,728 = 66.67 cubic feet
- Six pallets: 6 x 66.67 = 400 cubic feet
- Density: 3,900 pounds divided by 400 cubic feet = 9.75 pounds per cubic foot
Density is the measurement. Freight class is what a density scale assigns to it, and 9.75 lands at class 100. Class, weight break and the discount were all the same in August, so the linehaul cannot have moved.
The two quotes, line by line
A fuel surcharge is a percentage of linehaul, read from the carrier's own published table against the weekly diesel index named in the shipper's agreement.
- August: linehaul $740.00, fuel at 23.0 percent = 740.00 x 0.230 = $170.20, total $910.20
- October: linehaul $740.00, fuel at 27.5 percent = 740.00 x 0.275 = $203.50, limited access delivery $94.00, total $1,037.50
The increase is $1,037.50 minus $910.20 = $127.30, or 14.0 percent above August. It splits with nothing left over:
- Linehaul: $740.00 minus $740.00 = $0.00
- Fuel: $203.50 minus $170.20 = $33.30
- Limited access delivery: $94.00
- Check: $0.00 plus $33.30 plus $94.00 = $127.30
Two causes, neither of them a rate hike
The $33.30 is the diesel index doing what the Manifest described: the surcharge percentage stepped from 23.0 to 27.5, checkable against the carrier's own table. That part is the market, and it is small.
The $94.00 is not the market at all. Halvern's receiving moved this autumn to a site the carrier classifies as limited access. That accessorial attaches to the delivery address and would appear on any carrier's quote there.
Neither would change if the lane moved. The desk tests that: it requotes the same lane with a second connected carrier. That live quote comes back at $1,088.40, which is $1,088.40 minus $1,037.50 = $50.90 above the incumbent. Moving the lane would have given up a negotiated discount and paid more.
What a benchmark can and cannot be
A public index shows which way rates drift, not what your lane should cost. The only benchmark a shipper can fully verify is its own previous quote on its own lane, with the shipment details held constant. LanePilot does not publish a market-rate benchmark, and does not compare your rate with other shippers or an industry average. The lane performance it shows comes only from your own shipment history.
The fix
LanePilot is one system, a TMS and WMS for small and mid-sized manufacturers, distributors and warehouses. Live rates from the carriers connected to your own account come back side by side on one screen, and freight class is calculated automatically from weight and dimensions using standard NMFC density breakpoints. A saved shipment template for a lane you run often means the October requote starts from the same pallets and weight as August.
When you book, LanePilot generates the bill of lading and books on your own connected carrier account, prepaid. It is never in the payment flow, and it does not contact or negotiate with your carrier for you. You choose the carrier. Every requote draws a quote credit, so compare against the prior quote first.
Run this on your own desk
One. Before you blame the carrier, pull the last quote for the lane. Compare linehaul, fuel and accessorials line by line.
Two. Confirm the shipment is identical. Pallets, dimensions, weight, density, class.
Three. Check the fuel percentage against the carrier's published table and ask what triggered every accessorial.
If the linehaul is identical and the whole gap sits in fuel and accessorials, the market is not what moved your number. LanePilot is free to try at lanepilottech.com/signup.
