Truck Load Factor
How full a vehicle runs — empty space is wasted fuel and money.
Formula
Variables
Example
18 t on a 24 t truck: LF = 75%
How it works
Truck load factor compares the weight or volume actually carried with the vehicle’s maximum safe payload, then converts that ratio into a percentage. It works because dividing "used capacity" by "total capacity" tells you what fraction of the truck is being used; multiplying by 100 turns that fraction into a percent. A higher load factor usually means better utilisation, since more of the truck’s available carrying space is earning revenue instead of being wasted.
When to use it
Use this when planning shipments, checking how efficiently a fleet is being used, or comparing different route loads. It is especially useful for transport managers who want to reduce empty space, trips, and fuel costs.
Worked example, step by step
A truck can carry a maximum of 20 t. The actual load is 15 t. LF = (load carried / capacity) × 100 LF = (15 / 20) × 100 LF = 0.75 × 100 LF = 75% So the truck load factor is 75%.
Common mistakes to avoid
- Using the truck’s gross vehicle weight instead of its payload capacity
- Forgetting to multiply by 100, so the answer stays as a decimal
- Mixing up load factor with percentage of empty space, which is the complement of this value
Did You Know?
Return trips often run near-empty, which is why backhaul matching is a huge freight efficiency lever.
