KDP print economics begin with one formula
Amazon KDP describes a print royalty as the applicable royalty rate multiplied by the tax-exclusive list price, minus printing cost. The exact inputs vary by marketplace, format, page count, ink, trim size, and distribution channel.
royalty = (royalty rate × tax-exclusive list price) − printing costPrint-on-demand means an author usually does not buy inventory in advance, but each sale must still absorb the book’s production cost before a royalty remains.
What changes the printing cost
- Paperback or hardcover format.
- Black ink or color interior.
- Page count and trim size.
- Marketplace in which the order is printed.
- Any minimum fixed cost plus a per-page component.
Do not reuse a calculation from a different edition. A paperback, hardcover, large-print edition, and color edition can have materially different economics even when the manuscript is similar.
Price thresholds can matter as much as print cost
KDP publishes marketplace-specific list-price thresholds for print royalty rates. Its US example shows a $9.99 list price receiving a 60% rate and $9.98 receiving 50%, before printing cost is deducted. That one-cent difference can therefore change the royalty more than one cent.
Standard and expanded distribution are different channels
KDP’s help pages describe standard Amazon distribution using a 50% or 60% print rate depending on price and marketplace, while Expanded Distribution uses 40%, with printing cost deducted in each case. Expanded Distribution can widen availability but does not guarantee that a bookstore or library will order the title.
Model each channel separately. A price that leaves an acceptable standard-distribution royalty may be too narrow under the expanded rate.

Payment timing is not sale timing
KDP’s royalty documentation explains that payments generally arrive after the month in which the sale was reported, with longer timing for Expanded Distribution. Returns, taxes, currency conversion, and payment thresholds can affect the amount or date. Treat the dashboard as a reporting system, not immediate cash flow.
