Initial project idea: 

I wanted to create a way to see the interest on a car loan depending on duration, rate, monthly payments, and car price.

Tools I used: 

I used Microsoft Excel.

Challenges I faced:

Figuring out the exact math to do for the interest. 

Other Resources: 

None. 

Result:

I successfully made a way to put in a car's price and find the interest you will pay on a loan.
