A free financial planning tool to help you achieve financial independence.
Privacy First
All calculations happen locally in your browser. We never see, store, or transmit your financial data. Your numbers stay on your device — always.
Our Story
We built Coast FIRE Calculator because we needed it ourselves.
After years of grinding in demanding careers, we discovered the FIRE movement. But traditional FIRE felt overwhelming—save 70% of income for decades? That wasn't realistic for us. Then we found Coast FIRE: save aggressively for a few years, hit your number, then relax.
The problem? Most Coast FIRE calculators were either too complicated or hidden behind paywalls. We wanted something simple: enter a few numbers, get instant clarity.
So we built what we wished existed: a clean, fast, privacy-first Coast FIRE calculator. No accounts. No tracking. No ads cluttering the results. Just the math you need to understand where you stand.
We're not financial advisors. We're just people who figured out the math and wanted to share it.
The Team
Coast FIRE Calculator is built by a small team of software engineers and personal finance enthusiasts. We're based in different time zones but share the same goal: making financial independence concepts accessible to everyone.
What We Believe
- Financial literacy should be free
- Your data belongs to you, not us
- Simple tools beat complex software

What is Coast FIRE?
Coast FIRE is a financial milestone where you've saved enough that compound growth alone will fund your retirement — even if you never save another dollar.
Once you reach your "Coast Number", you can shift focus from aggressive saving to enjoying life, pursuing passion projects, or taking a lower-stress job. It's about freedom, not just retirement.
