How can I earn money with KDP?

You earn money on KDP through royalties on every sale. For coloring books, you typically keep about 60% of your list price minus Amazon's printing costs. So a 50 page book priced at $7.99 might earn you $2 to $3 per sale. The key is building a catalog of quality books in profitable niches like mandalas, animals, or kids themes. Many successful publishers create 10 to 50+ books to build consistent passive income. With InkChamp, you can quickly test different niches and scale your catalog without spending weeks on each book. Once published, your books can keep earning for years with no extra work.
