Kindle Unlimited is a library in your pocket. This is because the paid eBook subscription service lets you look up, read or listen to, and store digital titles and audiobooks on devices.

The format is useful for people who multitask and comprehend words better when read aloud. Furthermore, it helps the visually impaired read a book by hearing it.

Kindle Unlimited is brought to you by one of the world’s biggest online retailers, Amazon. The platform is among the most popular e-reader services because it has been around since 2014. In fact, it caters to millions of subscribers in the US, UK, Canada, Australia, Germany, Brazil, Mexico, France, Italy, Spain, India, and Japan.

How Much Does it Cost?

With the subscription, you can read any supported eBook or audiobook. You’ll get an account that can store up to 10 titles. You might be wondering why the service is called unlimited if there is a limit on how many eBooks or audiobooks can be downloaded per month. It is still unlimited because you can replace the 10 current titles after you are done reading those. Kindle Unlimited is similar to the borrowing and lending concept of real libraries, but there is no due date for returning or removing the books.

Kindle Unlimited vs Prime Reading

Learn more about the similarities and differences between Kindle Unlimited and Prime Reading

Kindle Unlimited is often confused with Prime Reading because both work almost the same way. The latter is just for Amazon Prime members. Amazon Prime is a paid service that lets subscribers get fast shipping, exclusive shopping deals, unlimited movie and TV show streaming, discounts, and more.

The two services have a 30-day free trial, 10-book-at-a-time borrowing limit, and accessibility via the Amazon Kindle app.


Library Size

Kindle Unlimited has a bigger catalog compared to Prime Reading. In fact, the former has millions of titles. The latter only has thousands.

Does that mean Kindle Unlimited is better than Prime Reading? Not necessarily. It depends on the kind of content readers want to get or discover.

Kindle Unlimited has a vast library but a big percentage of its available titles are from budding or self-published authors. Prime Reading, on the other hand, offers a smaller library yet has more mainstream or popular titles from award-winning authors and big-name publishing houses. Everything is also said to be editors’ recommendations.



Kindle Unlimited is less expensive compared to Prime Reading, price-wise. It costs just $9.99 per month as you already know. On the other hand, Prime Reading comes free with Amazon Prime but the membership requires you to shell out $12.99 monthly.

Both services seem to be at par given the features assessed above, so the readers’ choice will depend on the types of books, magazines, or audiobooks they want.


Kindle Unlimited vs Audible

Get to know the advantages and differences between Kindle Unlimited and Audible

Let us compare Kindle Unlimited with another Amazon company’s service, Audible, because the two also function similarly. Audible just focuses on providing audiobooks.


Library Size

Kindle Unlimited’s library is bigger than Audible’s entire selection. In fact, Audible only has about 200,000 audiobooks available. This will not matter, though, if the user prefers just audiobooks.



Kindle Unlimited is priced a bit higher than Audible’s $7.95 Plus plan yet cheaper than Audible’s $14.95 Premium Plus plan. Audible is free for Amazon Prime members paying $12.99 monthly. The Plus plan provides unlimited listening to select audiobooks, Audible Originals, and podcasts. The Premium Plus version lets members own one title per month that is purchasable via credits. Moreover, there are exclusive discounts on top of what the Plus plan offers.

Kindle Unlimited and Audible have 30-day free trials. Once the period is up or the subscription ends, the former removes your stored books. The latter does not operate on the same terms. As a result, you can keep your purchased Audible audiobooks.

Kindle Unlimited and Audible have slim advantages over each other based on end-user preference. The former wins by a hair strand if the reader does not prefer books or magazines being read aloud. The latter dominates by a little for audiobook fans. Is Audible worth it and better than Kindle Unlimited? There is no fixed answer because it depends on people’s reading needs.


Kindle Unlimited Verdict: Is it Worth the Penny?

It is now time for the verdict. You already know how Kindle Unlimited fares versus other eBook reading or listening services. So, let us then proceed to answer the ultimate question — is it worth your money?


Based on Reading Frequency

Kindle Unlimited is a good service to subscribe to depending on your reading habits. Yes, it is worth the penny if you are a frequent reader.

To break even with what you will be paying, you have to read up to four midrange- to $9.99-priced titles. Choosing titles that are not $1.99 or less or just simply reading lots of books is important because it helps you make the most of the subscription or exceed what you have paid for. This is easy if you are a bookworm.

Think twice before subscribing if you are a casual reader because reading more than 10 books monthly could be quite difficult. If you are not an avid reader and lack the time for it, the service might not be for you.

Based on Content Priority

Additionally, it is worth subscribing to the service if you prefer discovering new authors. Go for it if you have the taste for non-mainstream content. Wide readers who want to be first to read the potential bestsellers of the future will find it easy to scout titles using Kindle Unlimited on a mobile device. Furthermore, subscribing is a great way to support independent artists. It will benefit the digital book industry as a result.

If you want to stick mostly to the big publishers including Macmillan, HarperCollins, Simon and Schuster, Penguin Random House, and Hachette, then you should check out other services.


Based on Subscriber Lifestyle

Kindle Unlimited is worth it for people who are always on the go and multitasking. This is because you can splurge on books while surfing the web anywhere or communicating with your fellow digital bookworms on your mobile device. Gone are the days when digital reading is only available for Kindle device users.

If you have a lot of free time and are a fan of traditional print media, it is reasonable to not jump into the Kindle Unlimited trend. In fact, many other people are used to reading hard copies than soft copies of their favorite titles.


Love It or Hate It: Try It

Regardless if you have decided or not to commit part of your budget to Kindle Unlimited, you will agree that among its best features is the long trial period and the easy subscription cancellation. If you do not want to get it for the long run or run out of money to keep it, there are no service-cutting fees to worry about.

If you think you love it or hate it, better try it yourself because that’s still the most effective way to determine if Kindle Unlimited is the best option out there.
