The idea
You write a short, practical book on a narrow topic you know (a hobby, a software tool, a craft, a travel region) or design a useful low-content book (logbooks, planners, puzzle books), and publish it through Amazon Kindle Direct Publishing. Amazon prints each paperback on demand and delivers eBooks, then pays you a royalty.
Why it works
- No upfront print run: paperbacks are printed only after a customer orders.
- Royalty formulas are public: eBooks earn 35% of list price, or 70% minus delivery costs ($0.15/MB on Amazon.com) in eligible territories (KDP, updated Apr 2026).
- Since Jul 2026 the 70% eBook band on Amazon.com is $2.99–$12.99, up from $2.99–$9.99 (KDP list-price requirements).
- Paperbacks earn 60% of list price minus printing cost at $9.99 and above (50% below), so a 120-page black-ink book at $9.99 nets about $3.55 per sale in the US.
First steps
- Choose a narrow, evergreen topic you can explain better than existing books (read their 3-star reviews for gaps). Avoid health, medical and financial-advice topics.
- Outline 8–12 chapters solving one concrete problem; write the first draft in 3–4 weeks.
- Create a KDP account, complete tax information and publish the eBook and paperback together.
