## How KDP calculates paperback and hardcover printing costs
Q: How much does Amazon KDP charge to print a paperback or hardcover?
A: KDP charges a fixed cost per book plus a per-page cost, set by format, ink, paper, regular or large trim and the marketplace of the order, and subtracts it from your royalty. On Amazon.com a black ink regular trim paperback of 110 to 828 pages costs $1.00 plus $0.012 per page, so 300 pages cost $4.60; the same hardcover costs $5.65 plus $0.012 per page, or $9.25.
- Formula: Fixed cost + (page count x per-page cost)
- US paperback, black ink, 24-110 pages: $2.30 flat (large trim $2.84)
- US paperback, black ink, 110-828 pages: $1.00 + $0.012/page (large $0.017)
- US paperback, premium color, 42-828 pages: $1.00 + $0.065/page (large $0.08)
- US paperback, standard color, 72-600 pages: $1.00 + $0.0255/page (large $0.0402)
- US hardcover, black ink, 110-550 pages: $5.65 + $0.012/page (large $0.017)
- Large trim: Wider than 6.12 in or taller than 9 in
- No effect on cost: Bleed and cover finish

## KDP bleed size and minimum margins by page count
Q: What bleed and margin sizes does Amazon KDP require for a print book interior?

## KENP royalties: how KDP pays for Kindle+ pages read
Q: How does Amazon calculate KENP page-read royalties from the KDP Select Global Fund?
A: KDP Select books in Kindle+ (formerly Kindle Unlimited) are paid per Kindle Edition Normalized Page (KENP) read or listened to, the first time a subscriber reaches each page, up to 3,000 KENP per title per customer.

- Unit: Kindle Edition Normalized Page (KENP)
- Cap per title per customer: 3,000 KENP
- Pages counted: First read only; re-reads do not pay
- KENP rate: Marketplace fund / total KENP read in that marketplace

## KDP AI content disclosure: AI-generated vs AI-assisted
Q: Do I have to tell Amazon KDP if I used AI to write or illustrate my book?
A: You must disclose AI-generated content (text, images or translations) when you publish a new book or edit and republish an existing one. Content counts as AI-generated if an AI tool created it, even if you edited it heavily afterwards. AI-assisted content, which you created yourself and only edited, checked or brainstormed with AI, does not need to be disclosed.
- Must disclose: AI-generated text, images or translations
- No disclosure needed: AI-assisted content
- Images covered: Cover, interior images and artwork
- When asked: Publishing a new book or republishing after edits
- Heavy edits to AI output: Still AI-generated
- Brainstorming with AI: AI-assisted
