Lean FIRE

Lean FIRE is not about making deprivation permanent. It is about defining enough with precision.

By keeping durable living costs intentionally low, a household may reach financial independence with a smaller portfolio and a simpler operating system. Yet a lean plan can become fragile when it ignores healthcare, housing repairs, taxes, aging, family support, or the ordinary human desire for change.

In Lean FIRE, Elias Evermont shows you how to build a complete spending baseline, distinguish efficiency from sacrifice, calculate a realistic target, and design buffers around the categories most likely to rise. You will examine housing, transportation, food, insurance, healthcare, travel, family obligations, and the difference between temporary frugality and a life you can sustain for decades.

The book includes practical tables, stress tests, household examples, and a framework for deciding which expenses create genuine value. It also explains how to preserve flexibility when inflation, health, relationships, or location change.

Spend less where it does not matter. Protect what does. Build independence around a life that still feels abundant.
