- A paperback priced $9.99 or more earns 60% of list price minus printing; below $9.98 it drops to 50%. For a $9.99 black-ink book of 24-108 pages, printing runs about $2.30, so 60% of $9.99 ($5.99) minus $2.30 = about $3.69 per copy. The ebook 70% option applies to $2.99-$12.99 titles (band raised from $9.99 on July 7, 2026). KDP charges no setup fee; printing is deducted per sale, never upfront.
- Ask Muse for 10 underserved coloring-book niches and check each one's Amazon search results for competition. 2. Draft 30-40 consistent line-art prompts in one style (e.g. cozy cottage gardens, not generic mandalas). 3. Generate the art, then clean up stray lines and broken borders — sloppy pages get one-star reviews. 4. Lay out the interior in Canva or PowerPoint and build the cover in KDP's cover creator. 5. Publish on KDP, disclose AI-generated content where KDP asks, and write the listing around the exact phrases buyers search.
- A first book takes roughly 6-10 hours, mostly art cleanup and formatting, not prompting. Most coloring books sell a few copies a month; a $3.69 royalty means 30 sales a month is about $110. Discovery is the whole game: without Pinterest pins or short-form video pointing at the listing, the book sits unseen. Treat book one as a test of the niche, then double down only if it moves.
