The basics
Understand FIRE
The core concepts behind financial independence and early retirement, written for someone who wants the useful version first.
What is FIRE?
FIRE stands for Financial Independence, Retire Early. It is a movement focused on aggressive saving and investing so you can stop working for money decades earlier than traditional retirement. The core idea: if you can save 25x your annual expenses, you can live off investment returns indefinitely.
The 4% Rule
The most well-known FIRE guideline. If you withdraw 4% of your portfolio in year one and adjust for inflation each year after, your money has historically lasted 30+ years. So if you spend $40,000/year, your FIRE number is $1,000,000.
Your Savings Rate Matters Most
Income matters, but savings rate is the real lever. Someone earning $60K who saves 50% will reach FIRE faster than someone earning $150K who saves 15%. Every dollar saved also lowers the portfolio you need later.
Compound Interest is the Engine
At a 7% real return, your money doubles every 10 years or so. Start at 25 with $500/month and by 45 you can have over $260,000, even though less than half of that was money you contributed.
Choose your path
