Savings Rate Calculator
Years to financial independence at your savings rate.
Years to FI uses the standard FIRE math: 5% real return, 4% safe withdrawal rate, expenses stay flat in real terms. A 50% savings rate gets you to FI in about 17 years. A 10% rate takes about 50 years. The math is from Mr. Money Mustache's "shockingly simple math" post.

FAQ
Why does saving 50% retire you in 17 years?+
If you save half, you can live on half. Each year of saving funds about a year of retirement at the same lifestyle, plus whatever your investments compound to. The math gets striking past 40%.
What about taxes?+
The years-to-FI calculation assumes pre-tax savings will be roughly equivalent to your pre-tax expenses, which is a reasonable simplification but not gospel. Calibrate against your real numbers.
