FIRE Variants Explained

There are several approaches to Financial Independence:

  • 🔥Regular FIRE: 25× your annual expenses, allowing you to maintain your current lifestyle
  • 🌿Lean FIRE: 25× half your expenses, for a minimalist retirement
  • 💎Fat FIRE: 25× 1.5× your expenses, for a comfortable retirement with extras

Why Savings Rate Matters

Your savings rate is the most important factor in reaching FIRE. A 50% savings rate means you can retire in about 17 years, while a 70% rate cuts it to just 10 years.

  • 2Reduce expenses by cutting unnecessary subscriptions and lifestyle inflation
  • 3Invest in low-cost index funds to maximize returns
  • 4Track your spending to identify savings opportunities
