Financial Independence, Retire Early - Calculate your exact timeline.
The FIRE movement (Financial Independence, Retire Early) is based on the "Rule of 25." By saving 25 times your annual expenses, you can theoretically live indefinitely off a 4% annual withdrawal rate without running out of money.
Your savings rate is the single most important factor in reaching FIRE. Increasing your savings rate from 10% to 50% can reduce your time to retirement from 51 years to just 17 years.
