Lean FIRE

Click to expand the explanation

⌄

Lean FIRE focuses on a disciplined lifestyle and a lower annual spending target. It is designed for people who want financial independence with a leaner but still sustainable retirement budget.

Standard FIRE

Click to expand the explanation

⌄

Standard FIRE uses the widely referenced 4% rule as a baseline. The goal is to build a portfolio that can support your inflation-adjusted retirement spending for decades with a balanced withdrawal strategy.

Fat FIRE

Click to expand the explanation

⌄

Fat FIRE is for investors who want a premium lifestyle after retirement. The target corpus is substantially larger and is built to support more comfort, travel, flexibility, and discretionary spending.

Coast FIRE

⌄

Coast FIRE estimates how much you need invested early so compounding can do the rest. Once that number is reached, you may pause aggressive contributions and let time carry the portfolio to your retirement goal.
