What is FIRE and how do I calculate my FIRE number?
FIRE (Financial Independence Retire Early) is achieving financial independence to retire decades earlier than traditional retirement age. Your FIRE number = Annual Expenses ร 25 (based on the 4% rule). For example, if you spend $60,000/year, you need $1,500,000 saved. Use our calculator above to find your exact FIRE number and timeline.
What's the difference between Lean FIRE, Regular FIRE, and Fat FIRE?
Lean FIRE = 70% of your target (minimalist lifestyle, $25k-$40k/year expenses). Regular FIRE = 100% of target (comfortable lifestyle, $40k-$100k/year). Fat FIRE = 150% of target (luxury lifestyle, $100k+/year expenses). Our calculator shows when you'll reach each milestone.
What is Coast FIRE?
Coast FIRE means you have enough saved that it will grow to your full FIRE number by traditional retirement age (65) without any more contributions. You can 'coast' - work less, take lower-paying but more enjoyable jobs, or take extended breaks. Our calculator shows if you've reached Coast FIRE.
What is Barista FIRE?
Barista FIRE is when your savings + part-time income (like working at a coffee shop) covers your expenses. You need less saved because part-time work fills the gap. For example, if you need $60k/year and earn $20k part-time, you only need $1,000,000 saved (25x the $40k gap). Our calculator shows your Barista FIRE age.
Is the 4% rule safe for early retirement?
The 4% rule was designed for 30-year retirements. For early retirees (under 50), many experts recommend 3-3.5% for longer retirement periods. However, 4% remains a solid starting point. Our calculator lets you adjust the withdrawal rate to see the impact on your FIRE number.
How does geographic arbitrage help with FIRE?
Geographic arbitrage means moving to a lower cost-of-living area to reduce expenses and your FIRE number. For example, moving from San Francisco (COL 150) to Austin (COL 100) can reduce your FIRE number by 33%. Our calculator shows how adjusting COL affects your FIRE timeline.
What savings rate do I need to reach FIRE?
Higher savings rates = faster FIRE. At 50% savings rate, you can reach FIRE in ~17 years. At 65%, it's ~10.5 years. At 75%, it's ~7 years. The key is maximizing income and minimizing expenses. Our calculator shows your timeline based on your current savings rate.
Should I pay off debt or invest for FIRE?
Generally, if your debt interest rate is higher than expected investment returns (7-8%), pay off debt first. If debt rate is lower, invest for FIRE while making minimum payments. High-interest credit card debt should always be paid off first. Use our 'Should I Pay Off Debt or Invest' calculator to see the math.
