What is FIRE?
FIRE stands for Financial Independence, Retire Early. It's a movement focused on extreme savings and investment, allowing people to retire far earlier than traditional retirement age. The goal is to accumulate enough assets to generate passive income that covers your expenses indefinitely.
Calculating Your FIRE Number
Your FIRE number is typically 25 times your annual expenses (based on the 4% withdrawal rule). If you spend $40,000 per year, your FIRE number is $1,000,000. This amount, invested properly, has historically funded about 30 years of spending; early retirees often use 3-3.5% for extra margin.
The Power of Savings Rate
Your savings rate is the most important factor in reaching FIRE. Starting from zero with 5% real returns and a 4% withdrawal rate, a 10% savings rate takes about 51 years to retire. At 50%, about 17 years. At 70%, about 8.5 years. The math is compelling: every dollar you save both increases your assets and decreases the lifestyle you need to fund.
Questions people ask
What is a good FIRE savings rate?
Most FIRE enthusiasts aim for 50% or higher. However, even 25-30% can dramatically reduce your working years. The key is finding a sustainable balance between enjoying today and investing for tomorrow.
Is FIRE realistic?
Yes, but it requires intentional lifestyle choices. Many FIRE adherents achieve it in their 30s or 40s through high savings rates, low expenses, and smart investing. It's not about deprivation—it's about aligning spending with values.
What are the types of FIRE?
There are several variations: Lean FIRE (minimal expenses), Fat FIRE (comfortable lifestyle), Barista FIRE (part-time work for benefits), and Coast FIRE (stop saving, let investments grow). Choose the approach that fits your lifestyle.
