Frequently Asked Questions
Coast FIRE is a financial independence strategy where you save a lump sum early in your career that, with compound growth, will grow to your FIRE number by retirement age without needing additional contributions.
First, calculate your FIRE Number (annual spending divided by safe withdrawal rate). Then discount it back to today using your expected annual return over the number of years until retirement.
The safe withdrawal rate is the percentage of your portfolio you can withdraw annually without running out of money, commonly 4% based on the Trinity Study.
