Understanding potential earnings is a critical factor for any self-published author. While royalty percentages are often touted, the actual money you receive per sale can be complex, involving deductions for printing costs, distribution fees, and sometimes delivery charges or taxes. This is where built-in royalty calculators offered by self publishing book companies become invaluable.
These tools empower authors to estimate their potential earnings before committing to a price, helping them set a retail price that balances market competitiveness with desired profitability.
How Built-In Royalty Calculators Work
A royalty calculator, at its core, takes various inputs related to your book and the chosen platform’s fee structure to estimate your per-unit earnings. Key inputs typically include:
- Retail Price: The price you set for your book.
- Book Type: Ebook, paperback, or hardcover.
- Interior Type (for Print): Black & white, standard color, or premium color.
- Page Count (for Print): The number of pages in your book. This directly impacts printing costs.
- Trim Size (for Print): The physical dimensions of your printed book.
- Royalty Rate: The percentage of the sale price (or net revenue) the platform offers to authors.
- Marketplace/Store: Royalties and printing costs can vary by the country where the book is sold.
- Distribution Channel: Whether it’s direct sale, expanded distribution, or wholesale.
- File Size (for Ebooks): Some platforms (like Amazon KDP for 70% royalty) charge a “delivery fee” based on the ebook’s file size.
The calculator then performs the necessary deductions and calculations (e.g., Retail Price – Printing Cost – Distribution Fee = Royalty) to show you an estimated net earning per copy sold.
Self-Publishing Services with Built-In Royalty Calculators
Most major self-publishing platforms provide a royalty calculator or a detailed royalty estimation tool within their publishing dashboards. Here are some prominent examples:
1. Amazon Kindle Direct Publishing (KDP)
- Prominence: KDP offers one of the most widely used and detailed royalty calculators, available directly within the publishing workflow.

- Print Calculator: Highly detailed. You input trim size, interior type (B&W, standard color, premium color), page count, and choose the Amazon marketplace (e.g., Amazon.com, Amazon.co.uk, Amazon.de). It instantly displays the printing cost, minimum list price, and your estimated royalty per copy.
- Expanded Distribution: While the main calculator focuses on direct Amazon sales, it indicates how Expanded Distribution might affect minimum pricing.
