The pre-tour financial plan that lays out all expenses (per-diems, bus, fuel, hotels, crew salaries, production costs) against projected revenue (guarantees per show + back-end participation + merch). Used to determine whether the tour pencils: whether the artist makes money or loses money. Built by the tour accountant or tour manager in advance, reviewed weekly during the tour to track variance. Bad budgets get acts in trouble; tight budgets keep tours sustainable.
