Truck Cube Utilization at 65% target trailer fill rate: a worked example

Suppose target trailer fill rate falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. See how fully a trailer or container is loaded by comparing loaded cube against available trailer cube, with the gap to target.

The inputs for this scenario

  • Loaded cargo cube on the trailer: 3,000 ft³ (held at the documented default)
  • Usable trailer cube available: 3,816 ft³ (held at the documented default)
  • Target trailer fill rate: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Truck cube utilization = loaded cube ÷ trailer cube available.
  • Truck cube utilization works out to 78.62 % utilized at these inputs, and this is the headline figure for the scenario.
  • Gap to target fill works out to -13.62 points at these inputs.
  • Loaded cube works out to 3,000 ft³ at these inputs.
  • Trailer cube available works out to 3,816 ft³ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target trailer fill rate sits at 90% and the headline result is 78.62 % utilized, this scenario lands almost exactly on the baseline at 78.62 % utilized.
  • It computes what share of the trailer's usable cubic feet your loaded freight occupies, plus the point gap to your target fill rate. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Truck cube utilization: 78.62 % utilized (headline result)
  • Gap to target fill: -13.62 points
  • Loaded cube: 3,000 ft³
  • Trailer cube available: 3,816 ft³
