About this site

Most retirement calculators online are either too simple (just a number with no context) or trying to sell you something. I wanted one that showed all the FIRE strategies side by side with actual charts, and didn't ask for my email first.

So I built one. It's free, it runs entirely in your browser, and I don't store any of your data.

What's here

• Retirement calculator covering Standard, Lean FIRE, Fat FIRE, Barista FIRE, and Coast FIRE
• Compound interest calculator
• Savings rate calculator
• Monte Carlo simulations (1,000 random market scenarios)

The fine print

• This is not financial advice. I'm a developer, not a financial advisor.
• The math uses standard formulas (4% safe withdrawal rate, real returns after inflation).
• Nothing is stored server-side. Your numbers stay in your browser.
• There are no ads and no premium tier. If that changes I've sold out.
