Setting a selling price for self-published Kindle eBooks or KDP Print books (formerly CreateSpace) sold on Amazon begins with understanding your costs.
There are two components to book and eBook costs when selling on Amazon using KDP (Kindle Direct Publishing):
- The cost of sale: what Amazon charges the self-publisher for each unit sold
- The Amazon sales commission for selling your book
This article looks in detail at the formats sold and supported using KDP: Kindle eBooks and print-on-demand paperbacks produced using KDP Print. (Note that Amazon’s other book selling platforms, Amazon Advantage and SellerCentral/Marketplace, have different cost structures.

Looks pretty interesting, Chris. Thanks.
