What is the FIRE movement?

FIRE stands for Financial Independence, Retire Early. The goal is to save and invest enough money to live off investment returns indefinitely, allowing you to stop working far earlier than the traditional age 65. The core principle: save 50–70%+ of your income, invest aggressively in low-cost index funds, and reach a portfolio size of 25x your annual expenses (based on the 4% safe withdrawal rate).
