What this calculator works out

  • Projected revenue

    Ticket income across your attendance and price assumptions, plus sponsorship and other income you add.

  • Projected costs

    Fixed costs such as venue and staffing, plus per-attendee variable costs and processing fees.

  • Profit and margin

    What is left after costs, and how thin the margin is relative to total revenue.

  • Break-even attendance

    The number of attendees you must reach before the event stops losing money.

How to budget an event in three steps

  1. 1. Enter realistic assumptions. Start with the attendance you can defend, not the attendance you hope for.
  2. 2. Compare scenarios. Check the conservative case first — if it loses money, the plan needs changing.
  3. 3. Fix the biggest lever. Ticket price, sponsorship and fixed costs usually move the number more than anything else.
