The FIRE movement, short for Financial Independence, Retire Early, is built on a simple idea: save and invest a large share of your income so that investment returns eventually cover your living costs.

Beginners should start by tracking every expense for a month, because you cannot set a realistic savings rate until you know exactly where your money currently goes each month.

A useful first target is saving twenty to thirty percent of take-home pay, then raising that rate gradually as you cut recurring costs and increase income over time.

Low-cost index funds are the default investment choice for most FIRE followers, since they offer broad diversification without the need to pick individual stocks.

FIRE is a long-term plan measured in years, not months, so consistency, patience, and regular reviews matter far more than any single dramatic financial decision.
