Earnings from eBooks vary based on the type of distribution your readers have chosen while purchasing and also factors like data transfer fee based on the size of your eBook file. Some of the different ways an eBook can be sold are,
Distribution - A reader buys an eBook just like any other print book and the eBook is sent to the device they would read your book on.
Lending - The retailer lends the book to the reader for a limited period chosen by the reader.
Subscription - The distributor allows readers to read any book from their list by charging a monthly subscription fee.
Since it is difficult to predict how your readers might consume your content, the final earnings for each eBook sold can only be determined after a sale has occurred. Notion Press deducts a 20% processing fee from your monthly eBook earnings to account for international tax deductions, exchange rates and wire transfer fee.
