What is the FIRE Movement?

FIRE stands for **Financial Independence, Retire Early**. The core idea is to save and invest a significant portion of your income until your portfolio can generate enough passive income to cover your living expenses for the rest of your life.

The 4% Rule Explained

The 4% rule originated from the Trinity Study, which found that an investor could typically withdraw 4% of their initial portfolio value (adjusted for inflation each year) and have a very high probability of the money lasting at least 30 years.

Using this rule, your FIRE number is simply **25 times your annual expenses**. If you want a more conservative approach, you might use a 3% withdrawal rate, which would require a portfolio 33.3 times your annual expenses.
