How to Make Money with Amazon KDP

Amazon KDP – What It Actually Pays in 2026

Updated: 09.27.2026

While we were working on the Amazon Merch on Demand side hustle for this site, it got me thinking about Amazon’s other “upload it once and it sells itself” program: Kindle Direct Publishing, or KDP. Same idea as Merch, and honestly the same idea behind Redbubble and TeePublic too. You make something once, the platform handles the printing and the customer and the shipping, and you collect a royalty every time it sells. That’s the same hands-off mechanic behind most of the passive income ideas on this site, except instead of a t-shirt design, it’s a book.

Here’s what we found, the real math, the trap almost nobody mentions, a genuinely free add-on most people haven’t touched yet, and the one corner of this I found really interesting.

How the royalty actually breaks down

KDP has two separate royalty systems depending on what you publish, and the percentages everyone throws around aren’t the whole story, and one of the numbers below just changed for the first time since 2007.

For ebooks, you get 70% royalty if you price between $2.99 and $12.99, and 35% on anything priced outside that range. That $12.99 ceiling is new. Amazon raised it from $9.99 in July 2026, the first adjustment to that threshold in almost two decades. But here’s the part that’ll actually cost people money if they miss it: the change isn’t automatic. If your book is already priced between $10 and $12.99, it’s stuck in the 35% tier until you manually go update the price yourself in the Rights & Pricing section of your KDP dashboard. Nobody bumps you into the better rate for you.

On top of the royalty split, Amazon also takes a delivery fee out of your 70% cut, roughly $0.06 per unit on average, scaled by your file size. If your file is small, mostly text, that barely registers. If it’s loaded with images, that “70%” can quietly shrink toward something closer to the 35% tier.

Print books pay differently, and these rules also changed back in mid-2025 and haven’t moved since. You get 60% of list price minus the printing cost if your book is priced at $9.99 or higher, but only 50% if you price it below that. Same printing cost either way, so pricing a hair too low doesn’t just mean a cheaper book, it means a real cut to your royalty rate per copy.

There’s a third option if you enroll in Kindle Unlimited through KDP Select: instead of getting paid per sale, you get paid per page read, through something Amazon calls KENP (Kindle Edition Normalized Pages). The going rate has held steady in the $0.004 to $0.005 per page range through most of 2025 and into 2026 (it sat at $0.00517 as of August). A 300-page book read cover to cover nets you somewhere around a dollar to a dollar fifty, less than a straight $4.99 sale would pay. It can work out if people binge through a whole series, but it’s not automatically the better deal.

The trap nobody talks about: AI disclosure

This is the part that would’ve bitten me if I hadn’t dug in, so pay attention here.

Amazon requires you to disclose it if AI generated the actual text, images, or translations in your book. You do not have to disclose using AI to brainstorm ideas, build an outline, or clean up grammar on something you wrote yourself, that’s “AI-assisted” and it’s fine. But if you lean on AI to draft the actual paragraphs that end up in the book with only light edits, that’s “AI-generated,” and Amazon wants you to check the box.

Skip the disclosure and get caught, and Amazon’s own language is blunt about it: they’ll “reject or remove content that does not adhere to these guidelines and promptly investigate any book when notified of potential noncompliance.” In practice that’s meant books pulled without warning, royalties already earned on that title withheld, and Amazon going back through previously published titles that look AI-generated and demanding the disclosure get added retroactively. Repeated violations can get your whole account suspended. With detection getting better every year, this isn’t a corner worth cutting. If you’re using AI heavily to write the manuscript itself, just check the box. It costs you nothing in visibility and saves you the account.

One more thing worth doing before you hit publish, especially if you’re planning a series: run your title and any series name past a trademark checker. Trendlytic built theirs for apparel sellers, but a wordmark search doesn’t care what you’re selling, and it’s the same check either way. A reader flagged this to us recently: trademark risk isn’t a t-shirt problem, it’s a “you’re putting a name out into the world” problem, and that applies just as much to a book series as a POD design.

The free add-on nobody’s using yet

Here’s something that wasn’t really on the table when this piece first went up: KDP now lets you turn an eligible ebook into an audiobook for free, using computer-generated narration, through a feature called Virtual Voice. No studio, no narrator fee, no ACX contract. You pick from around 80 voices across several languages and accents, assign them by chapter if you want, preview and edit before it goes live, and set a price between $3.99 and $14.99. Royalty is 40% on a la carte sales, and if the source ebook is enrolled in KDP Select, the audiobook also lands in Audible’s Plus catalog for separate compensation.

It’s not going to sound like a professional narrator, and it’s still labeled a beta feature. But for something with zero cost and zero extra effort beyond clicking through the setup, there’s no real reason not to turn it on for a book that’s already published. It’s pure upside.

Worth knowing about but not worth planning around yet: Kindle Translate, Amazon’s AI translation tool that turns an eligible ebook into a new-language edition automatically. Right now it’s invite-only beta, so you can’t just opt in, but it’s a sign of where this is headed. If your trade-specific title ever does get the invite, a Spanish-language edition of an apprenticeship log book is a genuinely interesting long-tail idea.

The honest income picture

I’m not going to sell you a dream here, because the actual numbers tell a different story than the YouTube thumbnails do.

A decently positioned low-content title, think notebooks, planners, journals, might sell around 20 copies a month, earning somewhere between $20 and $70 for that one title. To clear something like $1,000 a month from low-content books alone, you’re typically looking at having 15 to 50 titles out there pulling their weight, not one or two. Most people who publish just a book or two with no real keyword strategy earn less than $100 total in their first few months.

And the obvious niches, generic notebooks, sketchbooks, basic planners, are about as crowded as it gets right now. Everyone with a laptop and an AI tool can crank one of those out in an afternoon, and a lot of people have. That’s not a reason to skip KDP entirely. It’s a reason to skip the obvious stuff.

Where I’d actually look, if I tried this

Here’s the part that connects back to why I looked at this in the first place. The saturated KDP niches are the ones anybody can make, generic journals, generic planners, the stuff with zero specific knowledge baked in. What’s not saturated, because it actually requires knowing something, is a log book or planner built around a specific trade.

Think about what a generic AI-content publisher has no way of getting right: an apprenticeship hour log formatted the way your state’s licensing board actually wants it tracked, a daily job-site log with the fields a foreman actually needs, a tool inventory log sized for what a mechanic or electrician actually carries, or a no-nonsense study companion for a trade certification exam. None of that is hard to build once you know the trade. But you have to know the trade to build it right, and that’s exactly the kind of edge a generic publisher chasing volume doesn’t have and can’t fake.

That’s a smaller, slower niche than “publish 50 notebooks and hope.” But it’s the kind of niche where the thing you already know from working the trade is worth more than another AI tool subscription.

Where that leaves you

Setting up an account costs nothing, you can start a start a KDP account and look around before committing to anything. My honest advice: don’t start with a generic notebook just to test the waters. Pick one specific log or guide tied to your actual trade, build it carefully, turn on Virtual Voice once it’s live since that part’s free, and see what happens before deciding whether to scale it into a second or third title. This works the same way print on demand does, whether that’s Redbubble, TeePublic, or Amazon Merch: the people doing fine with it treated it like a real small project, not a lottery ticket.
