FAQ
- What is Coast FI?
- Coast FI is the amount you would need invested today such that, untouched, it grows into your FIRE number by traditional retirement age (65). After hitting Coast FI, you only need to cover current expenses.
- Why does Coast FI matter?
- It changes how you think about work. Once you have it, every additional contribution is optional and compounds your future flexibility.
- Should I stop investing once I hit Coast FI?
- Most people don't — but the option to downshift becomes real. Many use it as the threshold to switch jobs, take a sabbatical, or work part-time.
