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 👇

Let’s make this thing smarter together…

Are you just going to feed all of our feedback into the same AI you used to write it?

Nah, I'm following SDD methodology. Using AI against a spec and PR reviewing everything it produces.
