Kindle Direct Publishing publishes a royalty help page and, inside a signed-in KDP account, a royalty calculator that prices printing cost and royalty for a list price, page count, ink, and marketplace. That is the right place to check what KDP would pay on one format you have already chosen.
Between that official preview and the decision still open — enroll this title in KDP Select for a 90-day exclusive window, or keep it wide — sits arithmetic the official tool does not do: how many Kindle Unlimited page reads match one paid sale, and whether this month's KU window still beats the other-store and Ingram volume you would keep by staying wide. This calculator does not try to reproduce KDP's live print cost. Paste the preview figure into the override box.
| Question | Where to answer it |
|---|---|
| What will KDP pay on this list price, page count, ink, and marketplace? | Amazon's own KDP royalty calculator, inside a KDP account. |
| What print cost does this exact trim and paper actually have? | KDP's print preview on that title. Paste it into this page's override box. |
| How many KU page reads equal one paid sale? | This calculator's 90-day readout — walked on Should I enroll this book in Kindle Unlimited?. |
| Does this 90-day exclusive window beat staying wide? | This calculator's exclusive-versus-wide totals, on numbers you type. |
Both, for different jobs. Amazon's KDP royalty calculator, published inside a KDP account, computes printing cost and royalty for a list price, page count, ink, and marketplace you already chose. It is the right place to check what KDP would pay on that one format. It does not compare Kindle Unlimited page reads to a paid sale, and it does not put a 90-day exclusive window next to the same book sold wide. This page does not try to replace KDP's live print preview — paste that figure into the override box — and instead answers the follow-on decision the official calculator leaves open.
Yes. Amazon documents the royalty calculator as part of Kindle Direct Publishing, used from a signed-in KDP account on a title you are publishing or have published. This page is a static file. It needs no Amazon account and never talks to Amazon.
