Frequently asked questions about how to achieve financial independence

How to achieve financial independence if I'm just starting out?
Savings rate, emergency fund, and passive income sources
Start by auditing monthly spending, lock in a savings rate that fits your household, and automate contributions to index funds or ETFs. Use the FIRE calculator each quarter so you always know your FI number and the next step toward financial independence.
How much money to retire at 40 or 50?
Run the FIRE calculator with your annual expenses
Enter your living costs, passive income goals, and target age to see how much money to retire at 30, 40, or 50. Combine the output with a 4% safe withdrawal rate so you understand the exact gap between your current savings and your retirement target.
What is the 4% rule and safe withdrawal rate?
Understand the Trinity Study and SWR calculator
The 4% rule comes from the Trinity Study, which showed that withdrawing 4% of a diversified portfolio each year historically preserved principal. Use a safe withdrawal rate calculator to adjust for inflation, income volatility, and different investment mixes.
What's the difference between Lean, Fat, Barista, Coast, and Flamingo FIRE?
Choose the FIRE type that matches your lifestyle
Lean FIRE prioritizes minimalist spending, Fat FIRE funds a premium lifestyle, Barista FIRE mixes part-time work with partial retirement, Coast FIRE lets your investments grow while you cover current expenses, and Flamingo FIRE is a midway step that combines lump-sum investing with gradual lifestyle upgrades.
