Amazon Kindle Unlimited isn’t included with a Prime subscription as standard, and unfortunately there are no price reductions available for Prime members. Prime Reading is the Prime-member equivalent automatically included with your subscription but offers a reduced range.
Keeping this in view, do you have to pay for Kindle unlimited if you have Amazon Prime?
Yes, you pay for Kindle Unlimited. It is a subscription service that allows you to borrow and read up to 10 books at a time. This is only for books that are part of Kindle Unlimited, which is a wide collection of authors and books. On the other hand, with Prime you do get Prime Reading for free.
Also know, how much is Kindle Unlimited with Prime? Is Kindle Unlimited free for Prime members? Kindle Unlimited is not free for Amazon Prime users and still costs the same $9.99 monthly fee as it does for non-Amazon Prime users. With this subscription, you can read an unlimited number of books each month, but keep in mind you can only hold onto ten titles at a time.
