What Is KDP and Why Calculating Earnings Matters
KDP is Amazon's self-publishing platform that allows authors to publish ebooks and print-on-demand paperbacks. With KDP, your earnings depend on:
- Book price – The retail price set for your ebook or paperback
- Printing cost – The cost of producing a physical book
- Royalty rate – The percentage of revenue you receive per sale
Accurately calculating royalties and profits ensures your pricing strategy is both competitive and profitable. Without proper calculations, you risk underpricing your book or leaving money on the table.
How the KDP Price Calculator Works
The calculator uses simple arithmetic to give you two key outputs:
- Royalty Amount: Your earnings after subtracting printing costs and applying the royalty percentage.
- Profit Per Book: The difference between the book price and printing cost, showing the total profit you make per sale.
