The FIRE Movement: A Minimalist Guide to Financial Independence, Retire Early
Master the 4% rule to calculate your exact FIRE number, slash expenses through intentional minimalism, and reclaim decades of freedom from the 9-5 grind.
The key objectives of The Rich Minimalist mini-manifesto are health and freedom. In modern life’s trap we are very unfree. We are especially financially unfree. Being financially free is the basis for freedom. The FIRE principles can provide a solution.
Introduction: The Race to Financial Freedom
The FIRE Movement—Financial Independence, Retire Early—is more than a financial strategy. It is a cultural phenomenon that challenges the traditional 40-year career path—an idea that I like very much at The Rich Minimalist (challenging rules just because of tradition).
At its core, FIRE is about optimizing your life to achieve Financial Independence as quickly as possible, giving you the option to Retire Early and pursue a time-rich life.
In this post I will demystify the FIRE movement, break down the core mathematical principles, explore the different strategies that have emerged, and provide you with actionable steps to accelerate your journey to financial freedom.
