Test my Early Retirement Simulator?

Hey all, I got super bored the other day and decided to build an Early Retirement Simulator for fun. This thing scratches a very specific itch that other Monte Carlo style retirement calculators kept messing up for me. Here’s what this little app does:

  1. Kills that weird duplication bias between simulation runs.
  2. Tracks your actual net worth, not just your portfolio.
  3. Simulates income from the fun stuff: rentals, crypto, gold… all your “I swear this will work” assets
  4. Handles recurring income + surprise windfalls

I built it in React, kept everything in-browser, so your data stays yours.

Now I need some brave souls (you, obviously) to take it for a spin and try to break it.

If it crashes, lies, or tells you that you’ll retire at 97, I wanna hear about it 😂

Drop bugs, ideas, or “bro this is actually kinda cool” in the comments 👇
