KDP Kindle Unlimited: KDP Select Enrollment Guide KDP Interior

Okay so you’re looking at KDP Select and whether you should enroll in Kindle Unlimited, right? I literally just walked a client through this yesterday while my dog was barking at the delivery guy, so it’s fresh in my mind.

What KDP Select Actually Means

Here’s the deal – KDP Select is basically Amazon saying “hey, give us exclusive rights to your ebook for 90 days and we’ll let you into our Kindle Unlimited program.” That’s it. You’re signing up for exclusivity in exchange for access to KU readers who can borrow your book instead of buying it.

You get paid from a global fund based on pages read. Not per borrow, per PAGE. That’s huge and a lotta people miss that. Someone borrows your book, reads 50 pages, you get paid for 50 pages. They read all 300 pages, you get paid for 300.

The rate changes every month. Right now it’s hovering around $0.004 to $0.005 per page, but I’ve seen it as high as $0.0055 and as low as $0.0035. Amazon announces it after the month ends which is kinda annoying when you’re trying to forecast income.

The Exclusivity Thing You Gotta Understand

So this is where people get tripped up. Exclusive means EXCLUSIVE. You cannot have your ebook:

On any other retailer (no Apple Books, no Kobo, no Barnes & Noble, nothing)
On your own website as a download
Free anywhere else on the internet
On Patreon or Gumroad or anywhere as a paid download

Paperbacks and hardcovers? Those are totally fine to sell anywhere. KDP Select only applies to the ebook version. I’ve got books in Select where the ebook is Amazon-exclusive but I sell the paperback on like six different platforms. No problem there.

But here’s what gets people in trouble – if you have even 10% of your ebook available for free on your blog as a “sample,” Amazon considers that a violation. They’re strict about this. I had a client who got their account flagged because they had three chapters up on Wattpad from like two years ago that they forgot about.

The 90-Day Auto-Renewal Trap

It auto-renews every 90 days unless you opt out. And you can only opt out during a specific window – the last 5 days before your current term ends. Miss that window? You’re locked in for another 90 days.

I literally set calendar reminders for all my books because I got burned on this early on. Had a book I wanted to go wide with, missed the window by two days, had to wait another 90 days. Cost me probably $800 in lost sales on other platforms.

How to Actually Enroll

Okay so the actual enrollment process is pretty straightforward but lemme walk through it step by step.

Log into your KDP dashboard. Find the book you wanna enroll. If it’s a new book you’re publishing, you’ll see the enrollment option during the publishing process. If it’s an existing book, you gotta go to your Bookshelf.

Next to the book title, click the three dots (the ellipsis menu thing). Select “KDP Select Info” from the dropdown.

You’ll see a checkbox that says “Enroll this book in KDP Select.” Check it. That’s basically it for the enrollment part.

But wait – before you click that checkbox, make sure you’ve actually removed your book from everywhere else. Like, don’t enroll and THEN start the removal process. Do it backwards. Remove first, then enroll.

Removing Your Book from Other Platforms First

This is gonna sound obvious but you’d be surprised how many people screw this up. If your book is currently on Draft2Digital, Kobo, Apple Books, whatever – unpublish it everywhere first.

And here’s the thing about unpublishing – it’s not instant. Draft2Digital says allow up to 2-3 weeks for complete removal from all retailers. Apple Books can take 24-48 hours. Kobo is usually faster, like 24 hours.

I wait at least a week after unpublishing before I enroll in Select. Some people say that’s overkill, but I’d rather be safe. Amazon’s algorithm can detect if your book is still for sale elsewhere, and they’ll reject your enrollment or worse, suspend your account.

Check everywhere. Google your book title with “epub” or “mobi” to see if there are any lingering copies floating around. Check your own website. Check if you uploaded it to any free platforms for promotion.

What You Actually Get with KDP Select

So beyond the Kindle Unlimited borrows, there’s other stuff that comes with Select enrollment:

Free Book Promotions

You get 5 free days per 90-day period. You can run your book as free for up to 5 days total – either all at once or split up however you want. Want to do 5 one-day promos? Fine. Want to do one 5-day promo? Also fine.

Free promos can be really powerful for getting reviews and building momentum, especially for new releases or series starters. I ran a 2-day free promo on book one of a series last month, got about 3,000 downloads, and the following week my sales on books 2 and 3 tripled.

But here’s the catch – during free days, you don’t earn anything. Not from downloads, not from page reads if people actually read during that promo. It’s purely for visibility and building your reader base.

Countdown Deals

You also get access to Countdown Deals, which are different from regular price promotions. With a Countdown Deal, you can discount your book for up to 7 days, and you still earn 70% royalties on the discounted price (assuming your regular price qualifies for 70%).

The countdown timer shows on your book’s Amazon page, which creates urgency. “Only $0.99 for 2 more days!” kinda thing.

Normal price promotions don’t have that timer, and if you drop below $2.99, you automatically get knocked down to 35% royalties. Countdown Deals let you price at $0.99 and still get 70%, which is huge.

I use Countdown Deals way more than free promos honestly. The revenue is immediate and you’re attracting buyers, not just freebie hunters.

Kindle Unlimited Borrows and Page Reads

This is the main event obviously. When someone with a KU subscription borrows your book, you get paid based on pages they actually read.

Amazon uses something called Kindle Edition Normalized Pages (KENP) to calculate this. It’s not the same as the page count you see on your book’s Amazon page. Amazon has their own formula that normalizes for font size, formatting, etc.

You can see your KENP count in your KDP reports. Usually it’s pretty close to your actual page count, but sometimes it’s way different. I’ve had 200-page books show up as 240 KENP and 300-page books show up as 285 KENP. No idea how their formula actually works.

Payment comes from the KDP Select Global Fund, which Amazon sets aside each month. Your share is based on your percentage of total pages read across the entire KU program.

So like, if 1 billion pages were read in KU this month, and your books accounted for 100,000 of those pages, you’d get 0.01% of the fund. Math is pretty straightforward once you get it.

Should You Actually Enroll Though

Okay so this is where it gets personal to your situation. KDP Select isn’t automatically the right choice for everyone.

I’ve got about 200 books published and maybe 60% are in Select. The rest are wide (meaning on multiple platforms). It depends on the genre, the series, the audience.

When Select Makes Sense

Romance, especially contemporary romance and romantic suspense – huge KU audience. I’ve got romance titles where 80-90% of my income comes from page reads, not sales. If those books were wide, I’d make maybe 30% of what I’m making now.

Sci-fi and fantasy, particularly series – also great for KU. Readers binge series, and KU subscribers love having unlimited access to a whole series.

New authors trying to build an audience – Select gives you access to tools (free promos, Countdown Deals) that can help with visibility. Amazon’s algorithm also seems to favor Select books a bit, though they’ll never admit it.

Books with high page counts – if you’ve got a 500-page novel, you can earn $2+ per borrow if someone reads the whole thing. That’s competitive with a sale, especially after Amazon takes their cut.

When You Should Go Wide Instead

Non-fiction, especially business and self-help – KU readers tend to prefer fiction. I’ve got non-fiction books that do way better on Apple Books and Kobo than they ever did in KU.

If you’ve already got established sales on other platforms – why kill that revenue? I’ve got a few older books that were making consistent money on Kobo before I really understood Select. Leaving them wide was the right call.

If you’re in a niche genre with international appeal – KU is heavily US and UK focused. Other countries have lower KU subscription rates. But if you’re selling direct or through international retailers, you might make more going wide.

Literary fiction or anything that wins awards – prestige markets aren’t really on Amazon. If you’re aiming for that audience, you probably need to be everywhere.

Monitoring Your Select Performance

So once you’re enrolled, you gotta actually track whether it’s working for you.

In your KDP dashboard, go to Reports. You’ll see columns for “Kindle Edition Normalized Pages Read” and “Kindle Unlimited & Kindle Owners’ Lending Library Royalties.”

That second one is your KU earnings. Compare it month to month. Is it growing? Stable? Dropping?

Also compare your KU royalties to your sales royalties for the same book. If KU is bringing in like $50/month and sales are bringing in $500, maybe Select isn’t crucial for that book. But if KU is $800 and sales are $200, you’d be stupid to leave Select.

I’ve got a spreadsheet – yeah I know, super exciting – where I track this for every book. Takes me maybe 30 minutes after each month’s royalties are finalized. But it’s how I make decisions about re-enrolling or going wide.

The Page Read Metric You Should Watch

Pages read per borrow is a good indicator of whether your book is actually resonating. If people are borrowing but only reading 10% of the book, that’s a problem. Either your blurb is misleading, your book has quality issues, or it’s just not connecting with KU readers.

Amazon doesn’t directly show you “borrows,” but you can kinda reverse-engineer it by watching your Kindle Unlimited & Kindle Owners’ Lending Library Royalties jump when a new borrow happens and pages start getting read.

Or you can use third-party tools. Book Report is one I use sometimes. It breaks down your KU data in more detail than KDP’s native reports.

The Unenrollment Process

Okay so say you’ve tried Select for 90 days and you wanna go wide. Or you just need to get out for whatever reason.

Log into KDP. Go to your Bookshelf. Find the book. Click the three dots menu again, go to “KDP Select Info.”

You’ll see your current enrollment status and your renewal date. There’s a button that says “Do not renew my book.” You can only click this during the last 5 days of your current term.

If you try to click it earlier, it’s grayed out. If you miss the window, you’re auto-enrolled for another 90 days and you gotta wait for the next window.

Once you opt out, your book stays in Select until your current term ends. So if you opt out on day 86 of your 90-day term, you’ve still got 4 days where you’re exclusive to Amazon.

After your term ends, you’re free to publish wherever you want immediately. But I’d still give it like 24 hours just to be safe, make sure Amazon’s systems have fully processed the change.

Common Mistakes People Make with Select

Alright so lemme run through the screw-ups I see all the time, sometimes from my own clients, sometimes from people in publishing forums asking “why did Amazon suspend my account?”

Enrolling Before Removing the Book Elsewhere

I mentioned this earlier but it’s worth repeating. People enroll in Select and THEN start unpublishing from other platforms. Amazon’s bots are fast. They’ll catch your book on Kobo or Apple Books, and they’ll either reject your enrollment or flag your account.

Always unpublish first. Wait a week. Then enroll.

Forgetting About Sample Chapters or Free Content

If you’ve got your first chapter on your blog, or three chapters on Wattpad, or a PDF of the first 20% on your website for newsletter subscribers – that’s a violation.

Amazon considers any substantial portion of your book being available elsewhere as a breach of exclusivity. Even if it’s free. Even if it’s just a sample.

You can have a short excerpt – like a few paragraphs or maybe one chapter if it’s super short. But use judgment. If someone could read enough of your book for free on your site that they wouldn’t need to borrow or buy it, that’s probably too much.

Not Tracking Renewal Dates

This one burned me early on. You’ve gotta manually track when your 90-day terms end if you want the flexibility to opt out.

I use Google Calendar. Every time I enroll a book, I set a reminder for 85 days later. That gives me the full 5-day window to decide whether to renew or go wide.

Amazon does send an email reminder, but it’s not always reliable. I’ve had emails go to spam or just not arrive at all.

Expecting Instant Results

KU isn’t a magic button. You enroll and… nothing might happen for weeks. Especially if you’re a new author with no reviews, no audience, no visibility.

Select gives you access to KU readers and promotional tools, but you still need to market your book. Run ads, use your free promo days strategically, get reviews, build your mailing list. Select alone won’t make you money.

I had a client – this was like two years ago – who enrolled in Select expecting to immediately start making thousands from page reads. They had one book, no reviews, no marketing. Three months later they’d made $12 total from KU. They blamed Select, but really it was just that nobody knew their book existed.

Using Free Promo Days Strategically

So you get 5 free days per enrollment period. Don’t waste them.

Best use case: new release launches or relaunching an underperforming book. Run a 2-3 day free promo, stack it with some promo sites like BookBub’s free listings, Robin Reads, Fussy Librarian.

Goal is to get hundreds or thousands of downloads, which boosts your ranking in Amazon’s system. After the free promo ends, your book has more visibility and hopefully some reviews, which leads to more sales and borrows.

For series, I almost always keep book one in Select and run periodic free promos on it. Get people hooked on book one for free, they buy or borrow books 2, 3, 4, etc. It’s a funnel.

Worst use case: randomly running a free day because you’ve got them and feel like you should use them. No marketing support, no strategy, no follow-through. You’ll get a handful of downloads from bargain hunters who’ll never read your book.

Timing Your Free Promos

Weekends are usually better than weekdays for free promos. More people browsing, more downloads.

Avoid major holidays unless your book is holiday-themed. On Christmas Day or Thanksgiving, people aren’t sitting around browsing for free Kindle books. They’re with family or traveling or whatever.

January is a great month for free promos because everyone’s got new Kindles from Christmas. Back-to-school season in August/September is also good.

I ran a free promo during the Super Bowl once because I wasn’t thinking. Got like 20 downloads. Learned that lesson.
