When can you stop needing a paycheck?
Financial independence isn't about retiring — it's about not needing to work. This calculator finds your FI number (25× annual expenses) and projects when your portfolio will reach it, based on your current savings, contributions, and expected returns.

FI vs FIRE — what's the difference?
FIRE = Financial Independence + Retire Early. Most online conversation focuses on the retirement part, but plenty of people pursue FI without ever planning to retire. Some examples:
- Independent professionals. Reaching FI lets a doctor, lawyer, or engineer turn down work they don't want. They keep practicing on their own terms.
- Career switchers. FI funds a switch to lower-paid but more meaningful work — teaching, nonprofits, creative work — without financial stress.
- Entrepreneurs. Reaching FI before launching a business eliminates the pressure to take an offer too early.
- Caregivers. FI lets you take years off to care for family without it derailing the rest of your life.
The math is identical. The difference is what you do after you hit your number.
Don't want full FI yet? Try Coast FI
Coast FI is the milestone where your invested portfolio — left untouched, no further contributions — will compound to your full FI number by traditional retirement age. It's a much smaller number than full FI, and it lets you stop saving aggressively while still reaching FI by 65.
