The short answer

LTL is priced from what the freight is, not from how much of the truck you booked. Weight, density, class, distance, handling and accessorials each move the number, and a minimum charge sets the floor.

Important to know

  • LTL pricing is not a smaller version of truckload pricing.
  • Accurate weight, dimensions and classification matter because the shipment can be inspected after pickup.
  • Carrier tariffs and customer pricing agreements can change how the same freight is rated.

The main pricing inputs

Weight

The carrier rates the actual shipment weight, subject to the applicable tariff and pricing agreement.

Density and class

NMFTA says freight class is based on four transportation characteristics: density, handling, stowability and liability.

The 2025 NMFC changes made density the primary factor for many more commodities, but the correct NMFC item still matters.

Use the freight density tool for density. Do not use density alone to guess a final freight class.

Distance and service network

Origin, destination and the carrier's network affect the linehaul portion of the rate.

LTL normally moves through a terminal network rather than on one dedicated truck.

Handling and stowability

Freight that is difficult to handle, cannot be stacked, is unusually long, or consumes space inefficiently can affect rating through classification or tariff rules.

Accessorials

Additional services such as liftgate, residential service, appointments, redelivery or detention are separate from the basic movement.

See accessorial charges.

Minimum charges

LTL tariffs and pricing agreements commonly include a minimum charge or rate floor. That means a very small shipment does not keep getting cheaper forever as weight falls.

Carrier minimums are not universal.

Do not assume

  • A large discount means the final invoice can fall below the carrier's applicable minimum charge.
  • Two carriers use the same minimum-charge rule.
  • The class written on the BOL will automatically remain unchanged after inspection.

Why LTL can feel less intuitive than truckload

Truckload is often discussed as a lane and truck-capacity problem.

LTL is a network-rating problem. The carrier is combining your shipment with other freight and applying its classification, tariff and operating rules.

That is why accurate shipment data matters so much.
