How to Subscribe to Kindle Unlimited and Borrow Books

Tap a step to see how to subscribe to Kindle Unlimited and borrow books.

  1. Search "Kindle Unlimited" on Amazon

    Go to the Kindle Unlimited subscription page on Amazon's website or app.

  2. Start your free trial

    Tap "Start your free trial", register a payment method, and your trial period begins.

  3. "Borrow" a book you want to read

    Find a title marked as eligible for Kindle Unlimited and tap "Read for Free" (or the equivalent) to borrow it into your library.

  4. Return a book to borrow a new one

    You can only have a set number of borrowed books at once (often around 10-20), so return titles you have finished to make room for new ones.

  5. Why this is useful

    Instead of buying books one at a time, you can borrow as many eligible titles as you like for one monthly fee, which can save avid readers a lot of money.

A better deal if you read a lot

If you regularly get through multiple books a month, a flat monthly fee that lets you borrow eligible titles freely can end up being much cheaper than buying each book individually.

Cancel before the trial ends to avoid being charged

If you cancel within the free trial window, you will not be charged anything, but once the trial period passes, the subscription automatically renews and billing begins β€” so it is worth setting a reminder near the end of the trial if you are not sure you want to keep it.

Frequently Asked Questions

Is every Kindle ebook included in Kindle Unlimited?

No β€” only titles marked with the Kindle Unlimited badge can be borrowed; not every ebook on the platform is included.

How many books can I have out at once?

Amazon caps the number of titles you can borrow simultaneously (commonly around 10-20 depending on your account), so you will need to return one before borrowing beyond that limit.
