Occupancy is people present divided by the venue’s capacity. Set an alert level below 100% so door staff can slow entry before the limit is reached.

Also called: Occupancy rate calculator, Capacity tracker.

## Inputs
- People present (default 450)
- Capacity (default 600)
- Alert level (unit %; default 90)

## Results
- Occupancy
- Spaces left
- Alert level reached at
- Status

## Formula

```
Occupancy % = People ÷ Capacity × 100;  Spaces left = Capacity − People;  Alert headcount = ⌊Capacity × Alert% ÷ 100⌋
```

Where:
- Capacity: the maximum number allowed
- Alert%: the level at which you start managing entry

## Worked example
1. Occupancy = 450 ÷ 600 × 100 = 75%.
2. Spaces left = 600 − 450 = 150.
3. Alert at 600 × 90% = 540 people.

**Result:** With 450 of 600 inside, the venue is 75% full, with 150 spaces left and 90 more admissions before the alert level.

## What the result means

Keep entry and exit counts running through the event; the occupancy at any moment is entries minus exits.

## Assumptions and limits
- The headcount is accurate at the moment you enter it.
- Capacity limits can apply to each room or zone separately, not just the whole venue.

## Questions

### Where does the capacity figure come from?

Usually from the venue’s licence or fire risk assessment. This calculator does not set it.

### Why set an alert level?

Queues and groups arrive in bursts. Slowing entry at 85–90% avoids going over the limit.
