Calculate your KU earnings from KENP (Kindle Edition Normalized Pages) read
Enter the KENP rate you want to model
KENP payout varies by month. BookBloom no longer labels an old historical rate as the current rate.
Use the effective rate from the month you are analysing, or enter a scenario rate for forecasting.

KENP (Kindle Edition Normalized Pages) is Amazon's standardized page count system for Kindle Unlimited. When KU subscribers read your book, you earn money based on pages read, not books borrowed. Amazon normalizes all books to a standard format to ensure fair compensation regardless of font size, margins, or formatting.
How It Works: Amazon reviews and announces the KDP Select Global Fund each month. KU earnings are determined from an author's share of eligible pages read in the relevant marketplace, so the effective KENP rate changes by reporting period.
Monthly rate: The effective KENP payout is not a permanent fixed number, so use the rate for the month you want to analyse. BookBloom keeps the rate editable rather than presenting a historical figure as current. For a broader KU strategy discussion, read our Kindle Unlimited strategy guide.
KDP does not publish one permanent KENP payout that can safely be hardcoded into a calculator. Amazon says the rate changes each month; your Prior Months' Royalties report is the best basis for the period you want to analyse.
Use KENP pages read and royalty from the same finalized reporting month. Keeping the period consistent avoids mixing one month's pages with another month's effective rate.
Enter a clearly chosen scenario rate and run more than one case. The result is a projection, not a promise that a future KDP Select fund will produce the same payout.
Amazon uses Kindle Edition Normalized Page Count (KENPC) with standard formatting settings to measure eligible pages read. Images, charts, and graphs can count toward KENPC. KDP currently caps credited KENP at 3,000 pages per title per customer.
If you compare KU with direct sales, use your own list price, actual eBook royalty assumptions, observed pages read, and the KENP rate for the same marketplace and period. There is no universal rule that KU or direct sales will earn more for every book.
KENP royalties are tied to the KDP Select Global Fund and pages read, so the effective payout per page can change from one reporting period to another.
For that reason, this calculator does not hardcode a historical month as the current rate. Enter the rate you want to analyse, then use the same input when comparing scenarios so your projections stay internally consistent.
This calculator estimates KENP earnings using the rate you enter. Here's how to use it consistently:
Use the effective KENP rate for the reporting period you are analysing, or a clearly chosen scenario rate for forecasting.
Use the KENP pages-read figure from the period you want to analyse. For projections, use a consistent average rather than mixing unrelated reporting periods.
See daily, monthly, and yearly projections using the exact rate you entered.
Use the comparison tool to see if KU or regular sales earn more for your book. Enter your price and see side-by-side earnings for 200, 300, and 500-page books. This helps you decide whether to enroll in KDP Select.
Change the rate input to test conservative and optimistic scenarios instead of assuming one historical rate will remain unchanged.
