Short example
A $1,550.00 fixed-cost workshop selling $45.00 tickets with $8.00 catering per attendee and ~$1.61 in fees needs about 44 attendees to break even. Below capacity of 80 — but requires strong promotion.
All calculations are estimates based on average platform fees. Real profits may vary depending on category, ads, and shipping.

How to use this calculator
- Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
- Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
- Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.
Formula
Break-even attendees = Total fixed costs ÷ (Ticket price − Per-attendee cost − Per-ticket fees)
Worked example
$1,550 fixed costs, $45 ticket, $8 catering, ~$1.61 fees.
- Net per attendee = 45 − 8 − 1.61 = $35.39
- Break-even = 1,550 ÷ 35.39 ≈ 44 attendees
- At 40 expected, projected profit ≈ −$135
Answer: ~44 attendees needed to break even
How it works
Event math is unforgiving because most costs (venue, marketing, staff) are locked in before ticket #1 sells. Setting a break-even number before you sign the venue prevents the most common event mistake.
How to interpret your results
- Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
- Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
- A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
- Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.
Common mistakes
- Assuming ticket price × capacity is 'the revenue' — you rarely fill capacity.
- Underestimating no-shows and last-minute cancellations.
- Forgetting per-ticket payment processing fees.
