Racked capacity is bays × levels × pallets per level. Floor capacity is the usable floor area divided by the pallet footprint, times how high you stack.

Also called: Pallet positions calculator, Warehouse space utilisation calculator.

## Inputs
- Storage type (options: Pallet racking, Floor stacking; default racking)
- Rack bays (default 40)
- Pallet levels per bay (incl. floor) (default 4)
- Pallets per level (default 2)
- Storage area length (unit m; default 30)
- Storage area width (unit m; default 20)
- Aisles and clearance (unit %; default 40)
- Pallet length (unit m; default 1.2)
- Pallet width (unit m; default 1.0)
- Pallets stacked high (default 2)
- Target utilisation (unit %; default 85)
- Pallets stored now (default 250; optional)

## Results
- Pallet positions
- Working capacity at target
- Current utilisation
- Free positions

## Formula

```
Racking: Positions = Bays × Levels × Pallets per level.  Floor: Positions = ⌊Area × (1 − Aisle%) ÷ Pallet footprint⌋ × Stack height.  Utilisation = Stored ÷ Positions
```

Where:
- Levels: beam levels plus the floor position, if used
- Aisle%: floor share taken by aisles, clearances and staging
- Stack height: pallets stacked on top of each other

## Worked example
1. Positions = 40 × 4 × 2 = 320.
2. Working capacity at 85% = 320 × 0.85 = 272.
3. Utilisation = 250 ÷ 320 = 78.13%; free = 70.

**Result:** The racking has 320 pallet positions; at an 85% working target that is 272, and 250 stored means 78% full.

## What the result means

Running close to 100% slows receiving and put-away because there is nowhere to move stock. If you are regularly above your target, plan extra space or reduce slow-moving stock before peaks.

## Assumptions and limits
- Every position takes one standard pallet.
- Floor stacking uses whole pallet footprints only; partial footprints are dropped.
- Racking load ratings, floor loading, fire-code clearances and stack stability are not checked. Follow the rack supplier’s and local safety requirements.

## Questions

### What aisle allowance should I use for floor stacking?

It depends on the forklift and layout. Measure a section of your own floor and divide the pallet area by the total area to get your figure.

### Does this tell me how many cartons fit on a pallet?

No. It counts pallet positions in the building, not cartons per pallet.
