Financial Independence Retire Early is a proven framework for building wealth and freedom. Here’s how it works in four simple steps.
Understand the FIRE Concept
FIRE stands for Financial Independence, Retire Early. It’s a movement focused on aggressive saving and investing so you can stop working years — or even decades — before the traditional retirement age.
Calculate Your Savings Target
Most FIRE strategies use the 4% rule: multiply your annual expenses by 25 to find your target portfolio size. Our calculators do the math for you based on your unique situation.
Track Investment Growth
Compound interest is the engine of FIRE. Even moderate returns grow dramatically over time. Our tools show you exactly how your investments could grow year over year.
Pick a Strategy & Take Action
Whether you choose Coast FIRE, Barista FIRE, or Fat FIRE, having a clear plan makes the journey manageable. Start with one calculator and refine your strategy as you learn.

Which Type Of FIRE Is Right For You?
There’s no one-size-fits-all path to financial independence. Understanding the different FIRE strategies helps you choose the right approach for your lifestyle and goals.
Coast Fire
You’ve saved enough that compound growth alone will fund a traditional retirement. You can “coast” — work just enough to cover current expenses without saving more.
Ideal for: People who want to downshift careers early
Barista FIRE
You leave your full-time job but work part-time (like a barista) to cover expenses and health insurance while your investments grow to full FIRE.
Ideal for: People who want freedom but enjoy some work
Fat FIRE
You retire early with a larger nest egg — typically supporting $100K+ in annual spending. No need to cut back on lifestyle.
Ideal for: Higher earners who want a comfortable retirement
Lean FIRE
Achieve financial independence with a minimalist lifestyle. Target $20K-$50K in annual expenses and retire much earlier than traditional timelines.
Ideal for: Minimalists who prioritize freedom over spending
Frequently Asked Questions
What is FIRE (Financial Independence, Retire Early)?
FIRE is a personal finance strategy focused on saving and investing aggressively — typically 50‑70% of your income — so you can build enough wealth to retire far earlier than the traditional age of 65. The core idea is that once your investment portfolio can cover your annual living expenses (usually calculated using the 4% safe withdrawal rate), you are financially independent.
What is Coast FIRE?
Coast FIRE means you’ve already saved enough that, even without additional contributions, your investments will grow to cover retirement by a traditional age (e.g., 60 or 65). You still work to pay current expenses, but you no longer need to save for retirement. Use our Coast FIRE Calculator to see if you’ve reached this milestone.
What is Barista FIRE?
Barista FIRE is a semi‑retirement strategy where you leave your full‑time career and take part‑time or lower‑stress work to cover living expenses (and sometimes health insurance) while your investments continue to grow. Try the Barista FIRE Calculator to estimate how much part‑time income you’d need.
What is Fat FIRE?
Fat FIRE targets a higher-than-average retirement spending level — typically $100,000 or more per year. It’s for people who want to retire early without significantly cutting their lifestyle. Our Fat FIRE Calculator helps you estimate the portfolio size you’ll need.
What is Lean FIRE?
Lean FIRE is a specific version of the Financial Independence, Retire Early (FIRE) movement where an individual saves enough to retire early by maintaining a minimalist, low-cost lifestyle.
How accurate are these calculators?
Our calculators use widely accepted financial planning assumptions like historical average market returns and the 4% safe withdrawal rate. They provide useful estimates for planning purposes, but they are not a substitute for personalized advice from a licensed financial advisor.
