What Is Coast FIRE?
Coast FIRE means you have accumulated enough money early in life that, if left invested, it will grow to your required retirement corpus by your target retirement age.
You continue working for living expenses — but you no longer need to invest aggressively for retirement.
It provides freedom without fully retiring early.
