Kindle Unlimited is most likely to be worth it if you read a lot and are happy to choose from its catalog rather than any book you want. It costs $11.99 a month in the US, so the question is how many of the books you would read each month are in that catalog. If you mostly read new releases from big publishers, check that your next few books are in the catalog before you subscribe, because Amazon doesn't promise every bestseller.

Kindle Unlimited is now called Kindle+
Amazon renamed Kindle Unlimited to Kindle+ in October 2026. It is the same kind of subscription: a monthly fee for unlimited reading from a set catalog. Kindle+ is separate from Amazon Prime, so a Prime membership doesn't include it.
What it costs
Kindle+ costs $11.99 a month in the US before tax. Eligible customers can start with a free trial, which turns into a paid monthly subscription when it ends unless you cancel first.

What you get
- Catalog: Amazon says it includes millions of eBooks, plus thousands of audiobooks, comics, manga and magazines.
- Bestsellers: Amazon says the catalog includes popular bestsellers, but not that every bestseller is in it.
- Audiobooks: thousands of audiobooks come as companion editions to selected eBooks, so you can switch between reading and listening at no extra cost. Some other Kindle books offer Audible narration for an added fee.
- Borrowing: you can hold up to 20 titles at once, with no due dates. Magazine issues count toward the 20.
- Devices: it works on Kindle e-readers and the free Kindle app for iPhone, Android, Mac, PC and the web.
How it compares with Prime Reading
Prime members already get Prime Reading, a rotating selection of books to read for free at no extra cost. If you have Prime and read only occasionally, it is worth checking Prime Reading before paying for Kindle+.
The catches
You don't own anything you borrow. When your membership ends, you lose access to the books you borrowed through it at your next billing date. Check that a specific author or series is in the catalog before you subscribe.
How to cancel
Go to amazon.com/kpcentral, choose Cancel Membership and follow the steps. You can also cancel through Amazon customer service. Your membership stays active until the next billing date. If you pay through a third party, such as an app store, you may need to cancel with that company instead.
Who should skip it
If you read a book or two a month, or already find enough in Prime Reading, buying the few books you want may suit you better than a monthly fee.
