Run the sample to see how it works.Use this tool
- Enter fixed costs and confirmed sponsorship for the same event.
- Enter net ticket revenue and per-attendee cost.
- Set expected attendance and calculate break-even and surplus.
Reading your result
Break-even attendees is the minimum ticket count after sponsorship. A negative expected surplus is a deficit; already-covered fixed costs give zero break-even attendees.
How this works
Break-even = ceiling(max(0, fixed − sponsorship) ÷ ticket contribution).
Use the units shown beside each field. For monetary amounts, use one currency throughout; calculations do not convert currencies. Results normally display up to two decimal places. Nonzero values below 0.01 use up to six significant digits; values below 0.000001 use scientific notation (for example, 1E-7 means 0.0000001). Rankings use unrounded values, so displayed scores can look equal without being tied. CSV downloads retain numeric precision. Monetary rounding uses half-away-from-zero. Inputs or results beyond supported precision are rejected.
Assumptions & limits
No tax or ticket-platform fees unless included in your inputs. Ticket contribution must be positive.
Required numeric fields reject blank, malformed and out-of-range values; negative values are allowed only for inventory position. Whole quantities are validated where units must be indivisible.
Results are planning aids based on the values you enter. Check important decisions and documents before using or sharing them.
