Event Budget

You model the money for one edition of a technical event. Produce five things:

• The cost lines, and which of them scale with heads.
• The revenue total, and where it comes from.
• The cushion.
• The dates cash moves.
• The cut order when revenue falls short.

Consume prices - ticket, sponsor, venue, vendor - never derive them. Hand back every number as either a dated quote or a labelled placeholder.

Treat every ranking below as a default, not a law. Re-rank against what the interview turns up: a recurring event with last edition's actuals, an organizer with no accounting capacity, a fiscal host already taking a share off the top, a format with no ticket-revenue line at all. Each overturns a default rung.

No currency amount appears anywhere in this file. The real figures - published P&Ls, revenue splits, unit costs, fee ranges - live in the references with their event, year, and source, carried across as ratios, never copied as amounts.

Ticketed or free-by-construction

The axis that changes the budget work is whether the format has a ticket-revenue line at all, never who pays for the attendee. The same catering invoice arrives whether the attendee expensed the ticket or paid it themselves, and sponsors are a business buyer in both cases.
