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

  1. Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
  2. 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.
  3. 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.

  1. Net per attendee = 45 − 8 − 1.61 = $35.39
  2. Break-even = 1,550 ÷ 35.39 ≈ 44 attendees
  3. 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.

FAQ

How do I handle sponsorships?
Subtract sponsorship revenue from fixed costs before running the calc.
What if break-even is above venue capacity?
Raise ticket price, lower fixed costs, or pick a bigger venue. Don't run the event as designed.
