From Written Word Media:
Kindle Unlimited has revolutionized the eBook experience for both readers and authors. Last year we took a look at how Kindle Unlimited affects authors and publishers. This year we want to take a closer look at the habits of KU readers compared to non-KU readers, and what that means for authors whose titles are enrolled in KU. We surveyed almost 1,000 readers and analyzed the results to find out what the takeaways are for the author community.
. . . .
The service currently costs $9.99/ month, and there are over 1.4 million titles available to enjoy. Most of the books available are either classics or titles published through Amazon imprints and Kindle Direct Publishing. This means that if, as a reader, you most frequently read titles by popular, best-selling authors, you may not find the names you recognize available in the KU library. To date, none of the major publishers have opted to make their titles available through KU.
KU readers can read as many books as they want per month. The one limitation is that readers can only have 10 Kindle Unlimited books downloaded to their devices at a time. This means that readers can’t “hoard” books the way that they may normally feel inclined to.
. . . .
When you divide the global fund by the payout by KENP payout, you get the total number of pages read in KU for a given month.
For this exercise let’s use the data from February 2017. The Fund was $16.8 million and the payout per KENP was about $0.005.
KDP Global Fund / KENP Payout = Total number of Pages read in the month on KU
16,800,000 / 0.005 = 3,360,000,000
That’s over 3 billion pages read! If we assume the average novel is 250 pages, we can back into the number of novels read: 3,360,000,000 divided by 250 gives you 12,440,000 average length novels read through KU subscriptions per month.
Based on our survey data, KU subscribers read about 5 books per month. We can use this data to estimate a subscriber count for KU.
Number of KU Novels Read / Number of Novels read by one Subscriber = Total Number of Subscribers
12,440,000 / 5 = 2,488,000 KU subscribers
2.5 million readers in KU is a lot of readers, and because our calculations are based on pages read it’s likely that the 2.5 Million number represents the active readers enrolled in KU. We would guess there are even more inactive users who are subscribed but are not reading. There are limitations with our data, and we’re making quite a few educated assumptions but we think it’s safe to assume that there at least 3 million readers in Amazon’s Kindle Unlimited.
. . . .
Over 71% of KU subscribers read 5 books per month or more. Compare that to non-KU readers, where only 57% of readers read 5 books per month or more. That makes sense since KU subscribers pay $9.99 per month for the service, there is an incentive to get your money’s worth. Also, people who read a lot of books will get the most value from KU as they were likely spending more than $9.99 per month purchasing books. 20% of our KU subscriber sample said they read more than 20 books per month!
