What is Lean FIRE?

Lean FIRE stands for "Lean Financial Independence Retire Early." It is a personal finance lifestyle and retirement approach where individuals aim to achieve financial independence by living on a minimalistic or very frugal budget. Unlike traditional FIRE, which often targets a more comfortable or luxurious standard of living in early retirement, Lean FIRE focuses on reducing expenses drastically to retire earlier with a smaller nest egg.

Simple Explanation

Lean FIRE means retiring early with just enough money to cover a modest lifestyle—focusing on essentials rather than extras. This path requires careful budgeting, frugality, and prioritizing needs over wants.
