If you're enrolled in Amazon Kindle Direct Publishing (KDP) and Kindle Unlimited (KU), our KENP Calculator helps you estimate your royalties based on Kindle Edition Normalized Pages (KENP) read and Amazon's current payout rate.
Unlike standard KDP royalties, Kindle Unlimited pays authors for pages read, not book sales. Whether you're a new author, an experienced self-publisher, or a publishing agency, this Amazon KENP Calculator provides a quick and accurate way to estimate your earnings and plan your publishing strategy with confidence.
Estimate your Kindle Unlimited page-read revenue — including a realistic low–high range, not just a single guess.
Want a book built for strong read-through and stronger KU earnings? We write, edit and publish for that.
