KDP prints your paperback on demand. That means we deduct the printing cost from your paperback royalty only when customers buy your book from Amazon or its partners. Printing cost depends on which Amazon marketplace (website) your paperback was ordered from.
Printing also cost depends on page count and ink type (black or color ink). Paper type, trim size, bleed setting, and cover finish don't affect printing cost. Click on the links below to see tables that summarize printing cost calculations by marketplace:
You can set list prices by marketplace as long as they’re higher than the minimum list price (based on Printing Cost / Royalty Rate) and lower than the maximum list price ($250 (US), €250 (EU) or Ұ30,000 (JP)). The time it takes to update your price depends on how great the change is. For information on timelines, including details on new publications and updates to published books, see our Help page
