This is a difficult question to answer because Amazon pays its authors differently depending on a variety of factors. But some general things to keep in mind are that Amazon pays its authors based on how many books they sell and how much the book costs. So, if an author sells a lot of books but they are all low-priced books, the author will probably make less money than if the author sells fewer books but at a higher price. Additionally, Amazon pays its authors a higher percentage of the book's price if the author enrolls the book in Kindle Unlimited or if the reader borrows the book through the Kindle Owners' Lending Library.
