Introduction
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.

The KENP Calculator estimates your Kindle Unlimited earnings using three primary inputs:
KENP Per Book
The Kindle Edition Normalized Pages assigned to your book by Amazon.
Pages Read
Total pages read by Kindle Unlimited subscribers.
KENP Payout Rate
Amazon's estimated payment per KENP page (changes monthly).
Formula Used
The KENP Royalty Calculator uses the following formula:
Variables Explained
| Variable | Meaning |
|---|---|
| Total Pages Read | Number of Kindle Edition Normalized Pages read by KU subscribers |
| KENP Payout Rate | Amazon's monthly payment per normalized page |
| Estimated Royalty | Your projected Kindle Unlimited earnings |
Example Formula
- Pages Read = 75,000
- KENP Rate = $0.0045
Then:
Estimated Royalty = $337.50
Since Amazon changes the payout each month based on the Kindle Unlimited Global Fund, actual earnings may differ slightly.
