About Community Event Budget Calculator

Contribution per attendee is the ticket price less the variable cost per head, and break-even attendance is the fixed costs divided by that contribution. The break-even count is the number that matters when deciding whether to book a larger venue, because fixed costs have to be covered before any surplus appears.

Formula

Break-even

attendees = ceiling(fixed costs / (ticket price - variable cost per head))

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
