Frequently asked questions
How is the KDP paperback royalty calculated?
Royalty = royalty rate × list price − printing cost. On Amazon.com the rate is 60% for books listed at $9.99 or higher and 50% below that. Printing (black ink, regular trim) is a flat $2.30 up to 110 pages, then $1.00 plus $0.012 per page.
Why is my royalty negative in the calculator?
Your list price doesn't cover the printing cost at that page count. KDP enforces a minimum list price for exactly this reason — raise the price or reduce the page count (tighter typesetting helps).
Do these rates apply to every Amazon marketplace?
No — this calculator uses Amazon.com (US) figures. Other marketplaces have their own printing costs and minimums, and expanded distribution pays 40% instead of 60%/50%. Always check KDP's official printing-cost tables before setting prices.
How do I reduce my printing cost?
Page count is the lever: professional typesetting typically fits the same manuscript in fewer pages than a Word export — without looking cramped. PaperbackKit typesets your book to KDP spec automatically, so you can see your real page count in minutes.
