How to use the Understanding FIRE (Financial Independence, Retire Early)

FIRE (Financial Independence, Retire Early) is a lifestyle movement with a simple goal: accumulate enough assets that passive income covers your living expenses forever. The EzCalcy FIRE Calculator helps you find your 'Freedom Number'—the exact portfolio size you need to say goodbye to mandatory work.

🔥 The 4 Types of FIRE

1. Lean FIRE (Essentialist)

Living on strictly essential expenses (e.g., < $40k/yr). For those who value freedom over luxury.

2. Fat FIRE (Luxury)

Retiring with an upper-middle-class lifestyle (e.g., > $100k/yr). Requires a much larger portfolio but offers zero compromise.

3. Coast FIRE (Front-Loaded)

You have saved enough that compound interest alone will hit your FIRE number by age 60. You only need to earn enough to cover current bills.

4. Barista FIRE (Hybrid)

Retiring from a high-stress career to a low-stress part-time job (like a barista) that covers ~50% of expenses or provides health insurance.

📉 The 4% Rule Explained

Origins from the 1998 Trinity Study. It states that if you invest in a mix of stocks (50-75%) and bonds, you can withdraw 4% of your portfolio in the first year of retirement, and adjust that amount for inflation every subsequent year, with a 95% chance of not running out of money for 30 years.

The Formula

FIRE Number = Annual Expenses × 25

⚠️ Risk: Sequence of Returns

The biggest threat to FIRE isn't running out of money at age 90, but a market crash in the first 5 years of retirement. If your portfolio drops 40% closer to retirement, your safe withdrawal amount drops permanently. Mitigation: Keep 2-3 years of expenses in cash/bonds (Cash Cushion) to avoid selling stocks during a downturn.

Strategy: How to Speed Up FIRE?

  • Increase Savings Rate: This is the most powerful lever. Saving 50% of income reduces working years to ~17. Saving 75% cuts it to ~7 years.
  • Geo-Arbitrage: Earn in a strong currency (USD/EUR) but retire in a low-cost country (Thailand, Portugal, India). This can cut your FIRE number by 50-70%.
  • House Hacking: Eliminate your biggest expense (housing) by buying a duplex or renting out rooms.
