Your Freedom Number

Financial freedom isn't vague. It's a specific dollar amount where your investments can cover your expenses with a high probability for a long retirement. Not "be rich." Not "have a lot." A precise, calculable number. The classic shortcut is useful, but it is not a promise of income forever: it was built around historical retirement horizons, so very early retirees and anyone facing unusual risks need a more conservative or flexible plan.

The rule was popularized by a landmark 1998 study, the Trinity Study. Researchers tested how portfolios held up across market conditions from 1926 onward. The answer became one of personal finance's most powerful rules.
