Frequently Asked Questions
What is a FIRE number?
Your FIRE number is the amount of money you need invested to be financially independent. It's typically calculated as your annual expenses divided by your safe withdrawal rate (usually 4%), based on the Trinity Study.
What is the 4% rule?
The 4% rule suggests you can withdraw 4% of your portfolio in the first year of retirement, adjusting for inflation each subsequent year, and have a high probability of not running out of money over 30 years.
