Methodology
Based on the work of Mr. Money Mustache and the Trinity Study. FI target = annual expenses / 4% (25x rule). Years to FI assumes current net worth as starting capital, monthly savings invested at the given return rate. The higher your savings rate, the lower your expenses, compressing time to FI from both ends. Results are estimates for educational purposes only.
Your savings rate is the single most important number in your financial life. It measures the percentage of your take-home income that you save and invest each month. Unlike your income or net worth, your savings rate directly determines how many years you need to reach financial independence.
The math is straightforward: according to the 4% rule (based on the Trinity Study), you need 25 times your annual expenses saved to retire. A higher savings rate accelerates this in two ways: you save more each month, and your lower expenses mean you need a smaller nest egg to cover them.
For example, saving 10% of your income means roughly 51 years to retirement. At 30%, it drops to about 28 years. At 50%, you can retire in roughly 17 years. And at 70%, financial independence is possible in under 10 years. These estimates assume your savings are invested and earn a reasonable return over time.
