What Is FIRE Movement (Financial Independence, Retire Early)?

The FIRE (Financial Independence, Retire Early) movement is a personal finance philosophy that emphasizes aggressive saving (typically 50-70% of income), frugal living, and strategic investing to accumulate enough wealth to cover living expenses indefinitely, enabling optional early retirement. The core principle relies on the 4% Rule (or variations), which suggests that a portfolio can sustain annual withdrawals of 4% of its initial value indefinitely. FIRE has several variants: Lean FIRE (minimal budget), Fat FIRE (comfortable lifestyle), Barista FIRE (part-time work for benefits), and Coast FIRE (enough saved that compound growth alone will fund retirement). The movement has grown significantly through online communities and personal finance blogs.
