The FIRE (Financial Independence, Retire Early) movement is a lifestyle movement with the goal of gaining financial independence and retiring early. The model became particularly popular among millennials in the 2010s, gaining traction through online communities via information shared in blogs, podcasts, and online discussion forums.[1][2][3][4][5]

Those seeking to attain FIRE intentionally maximize their savings rate by finding ways to increase income and/or decrease expenses, along with aggressive investments that again increases their wealth and/or income. The objective is to accumulate assets until the resulting passive income provides enough money for living expenses throughout one’s retirement years. Many proponents of the FIRE movement suggest the 4% rule as a rough withdrawal guideline, thus setting a goal of at least 25 times one’s estimated annual living expenses. Upon reaching financial independence, paid work becomes optional, allowing for retirement from traditional work decades earlier than the standard retirement age.
