💡 Quick Tip

Early retirement is a number, not a dream. Learn to use the 4% rule and calculate how much to invest based on your age to reach freedom.

The Path to your FIRE Number

The FIRE movement (Financial Independence, Retire Early) relies on accumulating 25x your annual expenses. In 2026, with pension uncertainty, creating your own "private pension" is vital. Your savings rate must be aggressive (30%+). The sooner you start, the more compound interest works for you.

📊 Practical Example

If you spend $24,000/year, you need $600,000 to retire. Starting at 30 from zero, investing $850/month in an index fund at 7% gets you there by age 53. You retire 14 years early.
