Even if you would be number 1 in the top authors list I will still ask you to abide by the community guidelines and keep your language professional and not curse. You’re always free to leave if you don’t wish to stay but on each item, when you click edit, and you set the price you get a small text that says “How much do I earn?” I believe clicking that would be much easier than cursing around the forums.
Sorry to put things this rough, but language like this is not tolerated here or to be quite honest on any marketplace. We’re here to help and answer all your questions, but we’re doing so courteously, so we ask the same thing of you. Cheers! 
Also, if the buyer fee in your case is 4$ you can gladly go ahead and use my tool to calculate the exact amount you’ll get.
Cheers and thank you!
