Formulas for calculate the revenue

[pablogalcu]

Hey guys, I need if anyone knows formulas to calculate the benefit you get for mining them I’d appreciate it, for those of you wondering why I just don’t use a calculator like WhatToMine, it’s because I’m doing a web page, I need the formula to put it myself in javascript and be able to calculate an entire column of a super table that has real-time data. The formulas I need are to calculate these 3 cryptocurrencies: RavenCoin (RVN), EtherumClassic (ETC) and Ergo (ERG). You guys will help me a lot if you tell me the formulas or you find out.
