This calculator is for the sellers of eBay that are trying to determine their net profit and ROI on the items they sell. This simple GUI will display these needed info after placing the necessary inputs.

• Java 18 (Most likely work with older versions)
• Swing Libary used for the GUI

I built a .jar file that you can run which will load the app that is located here

There are two ways to load the app

• Type in "java -jar EbayCalculator.jar" in your conolse (make sure you are in the right directory)
• There is a start.bat file which is a shell script that will perform the "java -jar EbayCalculator.jar" for you without worrying if you are in the correct directory or not. I suggest creating a shortcut of it, and then placing it somewhere where it can be easily accessed to prevent tedious clicking to get to the file.
