How much of my early-retirement budget should be flexible so I can cut spending in a downturn?

The more of your spending you can pause in a bad year, the safer any withdrawal rate becomes. A common target for FIRE planners is to have roughly 20-30% of your budget be discretionary, meaning travel, dining out, hobbies, and big optional purchases you could delay. Your essential floor, such as housing, food, insurance, and utilities, should ideally be coverable at a conservative withdrawal rate even after a market drop. Separating the two on paper before you retire tells you exactly how much you could trim if sequence-of-returns risk hits early. Retirees who can flex 10-25% of spending downward for a year or two dramatically improve portfolio survival in research from Morningstar and others.
