Show HN: A (provocative) tool to show the performance of your investment

[fastinfer]

Hey HN!

I'm learning front-end development, and to test my knowledge I made a tool for myself to predit the performance of a possible market investment. I'm surprised by the predictions, mainly by the inflation rate that eats so much capital... btw I used React, NextJS and UI by ShadCN. I'm not 100% sure about the correctness of the formulas used, even though I tested the results a lot.

Let me know what you think (and if there's any error)! Don't forget that it's not an accurate simulator, it's just a tool to give an idea.
