How the rate is set
Each month Amazon announces the KDP Select Global Fund and divides it by every KENP page read in Kindle Unlimited that month. More reading with the same fund means a lower rate; a bigger fund with the same reading means a higher one.
What the swings mean for your ads
Between January 2025 and September 2026 the rate moved 31%. If most of your ad-driven readers borrow through KU, your break-even moves by the same share. Re-check your break-even ACoS when the rate changes, and judge KU-heavy keywords on page reads, not ACoS.

Analyze my reportQuestions
What is the current KENP rate?
The latest published US rate is for September 2026: $0.005365 per KENP page, about $5.37 per 1,000 pages. The rate for a month is only known after that month ends.
Why does the KENP rate change every month?
The rate is the month's KDP Select Global Fund divided by all pages read in Kindle Unlimited that month. Amazon sets the fund, readers set the pages, so the rate moves with both.
When is the new KENP rate announced?
After the month closes, usually by the middle of the following month, when KDP reports update. Trackers like Written Word Media compile the rates as authors see them.
Is this rate the same outside the US?
No. These are US marketplace rates. Some marketplaces are paid at different rates; check your KDP reports for each store.
How does the KENP rate affect my ads?
A higher rate makes every Kindle Unlimited borrow your ads bring worth more, so your break-even ACoS rises with it. A 10% drop in the rate lowers what you can afford to bid on KU-heavy keywords.
