Show HN: Invest first and spend what's left

I made a tool to help with investing. I always love to save money. I didn’t know how to manage it properly to earn passively and overcome inflation. I found out about index funds, especially the S&P 500. The average return on this financial instrument is about 8–10% a year. I needed to understand how much I would earn over a period of time: 5, 10, 15, and 20 years from now. That’s why I built this product. I researched the formula and integrated it. I made pie charts and line charts for a beautiful illustration. For some geeks, I even represented the data in table form. If you are interested, check it out. Write a comment below.
