Keto

Does anyone have a good method or website for the keto calculator, I started keto on April 13th and I've lost some weight and chart everything in Myfitnesspal, but really want to know for sure how many grams of protein and fat I really should be eating, I don't do over 20 net carbs so the carbs I got that down, can anyone help me I just want to be doing keto correctly with calories and macros ???????
