TheEighthWonder

Inspiration

The rule of 72 would be the rule of 100 without compound interest.

What it does

This app lets you enter initial investment capital, APY, and length of time. Then with this information, the app calculates a graph showing the power of compound interest.

How we built it

I built it with a simple HTML page and then a client-side script which inserted a canvas element containing the graph

Challenges we ran into

I tried to use Node.js originally, but I eventually realized that I was adding unnecessary complexity.

Accomplishments that we're proud of

I am proud that I was able to pivot halfway through the hackathon.

What we learned

I learned how to use a event listener to actively format users input and I also learned how to use Charts.js

What's next for TheEighthWonder

I would like to add the ability for a user to add monthly contributions to their investment and watch monthly contributions compound with their initial investment.
