Major Difference

As we can see from the description of both subscriptions, the major differences between them are the cost and eBook library. The price is significantly different between both subscriptions that the Kindle Unlimited costs $12.99 per month, and you could say Prime Unlimited Reading is almost free for Prime members. The second significant difference is the eBook library. Kindle Unlimited users can access over 1 million Kindle eBooks and over 1 thousand audial books, rather than Prime Unlimited Reading, which only can access 1 thousand eBook. Moreover, the eBooks available for Prime members are changing per month that you might lose accessibility when you read an eBook on half.

There is a similar aspect of both subscriptions that you can only borrow eBooks from Kindle for reading on the screen. You do not own any Kindle eBooks, which means you will lose access to them once your subscription ends.

In conclusion, the Kindle Unlimited subscription is suitable for people who love reading, and the Kindle eBook library is extensive enough. If you read eBooks occasionally, we suggest you own an Amazon Prime subscription with multiple benefits.
