What is the Lean FIRE Calculator?

Lean FIRE is a minimalist approach to Financial Independence. It involves drastically reducing your living expenses so that you can retire much earlier on a significantly smaller portfolio. Lean FIRE practitioners typically aim for an annual budget of $40,000 your local currency or less. By stripping away luxury expenses, you can escape the rat race decades ahead of your peers.

How to Use This Tool

  • Housing, Transport, Food: These are the “Big Three” expenses. Reducing these inputs will drastically lower your required portfolio.
  • Other Expenses: Calculate your bare-minimum survival budget.
  • Savings Rate: Notice how high your savings rate gets when you reduce your expenses!

Frequently Asked Questions

Is Lean FIRE dangerous?
Lean FIRE leaves less room for error. Because your budget is already stripped to the bare minimum, unexpected expenses or market downturns can be challenging to navigate without returning to work. Building a larger cash buffer is recommended.
Where do Lean FIRE retirees live?
Many locals pursuing Lean FIRE practice geo-arbitrage—moving from high-cost-of-living (HCOL) areas like a major city or another major city to lower-cost provinces like Alberta, Nova Scotia, or even retiring abroad to countries with a lower cost of living.
