Savings Rate
Your savings rate is the percentage of your income you save and invest rather than spend. It is the single most powerful lever for reaching financial independence — more important than investment returns for most people.
Savings rate = (Income − Spending) ÷ Income × 100. If you earn $80,000 and spend $60,000, your savings rate is 25%.
At a 50% savings rate and 7% real returns, financial independence takes roughly 17 years from a zero starting point. At 10%, it takes 43 years. The relationship is non-linear: doubling your savings rate more than doubles the speed to FI.
The FIRE community focuses intensely on savings rate rather than income, because someone earning $50,000 and saving 50% will reach FI faster than someone earning $150,000 and saving 10%.

- FIRE Number
- Your FIRE number is the portfolio size needed to retire early and live off investment returns indefinitely. It is calculated as your annual expenses multiplied by 25 (the inverse of the 4% safe withdrawal rate).
- Financial Independence (FI)
- Financial independence means having enough invested assets to cover your living expenses indefinitely without working. It is the point where your investment returns equal or exceed your annual spending.
- Net Worth
- Net worth is the total value of everything you own (assets) minus everything you owe (liabilities). It is the most comprehensive single-number measure of financial health.
