How Amazon KDP Royalties Work
- Fixed Cost: KDP charges a fixed print cost ($1.00 for standard B&W paperbacks on Amazon.com).
- Per Page Cost: Additional per-page fee ($0.01625/page) is added for paperbacks over standard base counts.
- Spine Thickness: Books under 100-130 pages typically cannot accommodate spine text in Canva/KDP templates due to trim safety.
