Each ticket contributes its price, less fees and the cost of serving that attendee. Divide the fixed costs that sponsorship does not cover by that contribution to get the break-even attendance.

Also called: Event break-even ticket calculator.

## Inputs
- Fixed event costs (default 20000)
- Sponsorship and other fixed income (default 5000; optional)
- Average ticket price (default 60)
- Ticketing and payment fees (unit %; default 5; optional)
- Cost per attendee (default 22; optional)
- Venue capacity (unit people; default 500)
- Currency

## Results
- Paying attendees to break even
- Contribution per attendee
- Ticket revenue at break-even
- Share of capacity
- Profit if sold out

## Formula

```
Contribution = Price × (1 − Fee%) − Cost per attendee;  Break-even attendees = ⌈(Fixed costs − Sponsorship) ÷ Contribution⌉
```

Where:
- Fixed costs: costs that do not change with attendance
- Sponsorship: income that does not depend on ticket sales
- Contribution: what each extra attendee adds after fees and their own cost

## Worked example
1. Contribution = $60 × 0.95 − $22 = $35.
2. Costs to cover = $20,000 − $5,000 = $15,000.
3. 15,000 ÷ 35 = 428.6, rounded up to 429 attendees (85.8% of 500).
4. Sold out: 500 × $35 − $15,000 = $2,500 profit.

**Result:** The event breaks even at 429 paying attendees, 85.8% of capacity; a sell-out makes $2,500.

## What the result means

If break-even needs more than about three-quarters of capacity, the event has little room for a slow sale. Raise the price, cut fixed costs or secure more sponsorship before committing.

## Assumptions and limits
- All attendees pay the average price; complimentary guests should be added to the cost per attendee or fixed costs.
- Uses one average price; tiered or early-bird pricing changes the mix over time.

## Questions

### Why round up?

You cannot sell part of a ticket, and 428 tickets would leave the event slightly short.

### Should staff and speakers count?

Count their costs (in fixed costs or cost per attendee) but not as paying attendees.
