A truck is full when it reaches its weight, volume or floor-space limit, whichever comes first. This shows the load as a percentage of each and the one that limits the load.

Also called: Trailer fill rate calculator, Load factor calculator.

## Inputs
- Load weight (unit kg; default 18000)
- Payload capacity (unit kg; default 24000)
- Load volume (unit m³; default 70)
- Cargo space volume (unit m³; default 90)
- Pallets loaded (default 26)
- Pallet positions (default 33)

## Results
- Load utilisation (highest of the three)
- Limiting factor
- Weight used
- Volume used
- Pallet positions used
- Spare payload
- Spare volume

## Formula

```
Weight % = Load ÷ Payload × 100;  Volume % = Load volume ÷ Capacity × 100;  Pallet % = Pallets ÷ Positions × 100;  Utilisation = the highest of the three
```

Where:
- Payload: the most cargo weight the vehicle may legally carry
- Capacity: usable internal cargo volume
- Positions: pallet spaces on the floor

## Worked example
1. Weight: 18,000 ÷ 24,000 = 75%.
2. Volume: 70 ÷ 90 = 77.78%.
3. Pallets: 26 ÷ 33 = 78.79%, the highest, so floor space limits this load.

**Result:** The truck is 78.79% utilised; floor space runs out before weight or volume.

## What the result means

The highest percentage is how full the truck really is. If floor space limits you but volume is low, stackable pallets or double-decking could add load; if weight limits you, adding light, bulky freight is the way to fill it.

## Assumptions and limits
- Weight, volume and pallet positions are independent limits; axle loads are checked separately.
- A load within payload can still overload one axle. Use the axle load calculator to check how it is distributed.

## Questions

### Why not average the three percentages?

A truck can take no more once any one limit is reached, so the highest figure is the true fill rate.

### What counts as payload?

The permitted gross vehicle weight minus the vehicle’s unladen weight, including driver and fuel as your rules require.
