Amazon Changes Kindle Unlimited to Kindle+: AI Audiobooks Enter Subscription Pool, Payments Based on "Pages Listened"

On October 22, Amazon rebranded Kindle Unlimited to Kindle+. The subscription price remains the same at $11.99 per month, allowing users to borrow up to 20 books at a time, with all existing reading records, bookmarks, and notes carried over. On the surface, this appears to be a simple rebranding, but there's more to it: audiobooks have been added to the subscription pool. Readers no longer need to purchase audiobooks separately; they can now listen to them as part of their subscription.

For authors, the key changes are in two areas: format and billing. Previously, the subscription pool only included "reading," but now "listening" is also part of the same system. How the money is divided, who can join the pool, and the unit price are the critical points. The help page clearly outlines the first two, but the third is not specified.

Kindle Unlimited becomes Kindle+, AI audiobooks join the pool

1. The Change Is Not in Price, But in Combining "Reading" and "Listening" into One Account

Amazon's message to authors is straightforward: In Kindle+, both reading and listening activities by subscribers are calculated based on Kindle Edition Normalized Pages (KENP). You receive your share from the KDP Select Global Fund. If a book is borrowed and the reader reads up to page 50, you get paid for those 50 pages. If they then listen to pages 51 to 100, you get paid for those 50 pages again.

There are three important details in the rules:

  • Each page is paid for only once. If a reader reads and then listens to the same page, or vice versa, it is not counted twice; it is considered a "re-read."
  • Simultaneous reading and listening are charged at the higher rate. During immersive reading (Read and Listen), if the rates for reading and listening differ, the higher rate is applied.
  • Audiobooks are currently available only in the U.S.. Audiobooks are currently only available in the U.S. market, with plans to expand to other markets, though no timeline has been provided. Authors from other countries can sign up to have their audiobooks promoted to U.S. listeners.

2. AI-Generated Audiobooks Are Automatically Included, but Language Is a Barrier

The new audiobooks in Kindle+ come from two sources. The first is Amazon's Virtual Voice, which is machine-generated narration. The inclusion is automatic: if an e-book is in KDP Select and has a Virtual Voice version, the audiobook version is automatically added to the pool without the need for registration. However, if you want to separate the e-book and audiobook, you must remove the audiobook version.

However, this path is currently closed to Chinese authors. Virtual Voice is an invitation-only beta, and it requires the primary language of the e-book to be English, Spanish, Italian, or French. The help page states that Japanese is not supported, and Chinese books are not on the list. Additionally, the e-book must be reflowable (fixed-layout picture books are not eligible), the title must be within 200 characters, the number of chapters must not exceed 1000, and the book cannot be in the public domain.

In other words, AI audiobooks are currently a boon for English market authors, but Chinese authors can only watch from the sidelines.

3. The Path of Human Narration: Four Hurdles, Royalty Share Temporarily Not Eligible

The second option is human narration through ACX (Amazon's audiobook production platform). To get into Kindle+, all four of the following criteria must be met:

  1. The corresponding e-book is in KDP Select;
  2. The audiobook is exclusively distributed on Audible;
  3. Whispersync for Voice (read and listen synchronization) is enabled;
  4. The production method is "pay per production," meaning you pay the narrator upfront.

The fourth criterion is the easiest to overlook. Audiobooks produced under the Royalty Share model are not currently eligible: Amazon is still working on how to split the subscription revenue by page count with narrators, and there is no short-term solution. Books that saved on upfront costs by using the Royalty Share model will not qualify this time; to qualify, they need to switch to the upfront payment model or re-produce a new version.

This is the most practical statement: the audio subscription pool is open to authors who have already paid for audiobook production.

4. Where Does the Money Come From: One Pool, No Details on Additional Funding

All income still comes from the KDP Select Global Fund. The official statement is that additional funds have been added to the fund to expand audio content, but the amount of the additional funding and the per-page listening rate have not been disclosed.

This means it is currently impossible to calculate how much you can earn from having a chapter listened to. What is certain is the distribution method: earnings are allocated based on the proportion of pages read and listened to from your book out of the total pages consumed by all subscribers, and the payments are combined with other KDP royalties on the same invoice and payment cycle. The total amount for the previous month is announced mid-month, and the payment is made approximately 60 days after the end of the month. Based on past experience, the rate for e-books is about $0.004 to $0.005 per page, so a 250-page book read by one subscriber would earn around $1 to $1.25. If the listening rate is similar, the earnings would be comparable. The first report with listening data is expected to be available around mid-November.

5. The Most Important Thing to Check This Month: KENP Numbers Have Decreased

In late October, many authors noticed a significant drop in their KENP numbers, with historical months also being adjusted. A third-party analysis suggests that some authors saw a decrease of 40% to 50%.

Before jumping to the conclusion that your earnings have decreased, it's important to understand that KDP's KENP report has always included two types of data: pages read through Kindle Unlimited and pages listened to through Audible Plus, with the payments coming from different pools. According to Amazon's report on October 31, the listening data from Audible Plus has been moved to the Audible Royalties column, and historical data has been relocated as well. For authors who have created virtual narrations, this change mostly means that the money has been shifted to a different column, not that there is less money.

However, there is one group for which this explanation is incomplete: authors without virtual narration books. If their numbers have also dropped, there is no official explanation yet. These authors should compare their September and October statements side by side, rather than just focusing on the total numbers.

Listening and reading now share one account

6. Three Judgments for Authors

First, identify which pool you are in. Chinese books currently do not qualify for virtual narration, so they won't benefit from this automatic increase. The real beneficiaries are authors who write in English (or Spanish, Italian, French) and those who have done pre-paid human narrations.

Second, the cost of exclusivity has increased. KDP Select's 90-day exclusivity already blocks other platforms, and now the audiobook version is also tied to it. Adding another distribution channel comes at the cost of not being able to sell the audio elsewhere. Whether it's worth it depends on the actual page performance of your book, not just the fact that there's an additional audiobook option.

Third, AI narration is becoming an infrastructure, not a selling point. As platforms offer free machine narration and include these in subscription pools, reader expectations for "having an audiobook" will be normalized. The real value will come from whether the content itself can keep listeners engaged—something that tools cannot replace.
