Every few months this argument starts again. Someone posts their KENP graph, someone else announces they went wide and doubled their income, and the comments fill up within an hour.
Most of it is vibes. Let’s use actual numbers instead.
This is not a piece telling you to go wide, and it isn’t a piece telling you to stay in KU either. It’s the underlying math, plus a way to test the question on your own catalog without betting an entire year on a guess.
What The KENP Rate Is Actually Doing
Start with the money, because everything else follows from it.
The KENP rate is what Amazon pays you per page read in Kindle Unlimited, and it moves every single month. According to Authors Game’s breakdown of KENP economics, the rate in May 2026 sat at approximately $0.004888 per page.
For context, the 2025 average was around $0.00445 and the 2024 average was about $0.0042. October 2025 reached roughly $0.005007, a five-year high, while January 2025 dipped to about $0.004091.
So the rate is drifting upward overall, but it swings considerably inside any given year.
The global fund has grown alongside it, starting at $2.5 million back in July 2014 and reaching around $66.9 million a month by May 2026.
Here’s what all that means in practical terms. A 300-page novel read all the way through earns you roughly $1.35, a 500-page book earns about $2.25, and a three-book box set can clear $10 to $12 per complete read-through.
That’s the figure worth holding in your head — not the rate itself, but the actual per-book payout.
What Exclusivity Actually Costs
KDP Select requires exclusivity on the ebook, and that’s the fundamental trade you’re making.
You can’t sell that ebook on Kobo, Apple Books, Barnes & Noble, or from your own store while it’s enrolled, and the terms renew in 90-day blocks.
For a lot of dark romance authors, that trade has been perfectly reasonable, because romance is a heavy KU genre. Authors Game notes that somewhere between 70% and 89% of top titles in romance carry the KU badge, which means your readers are already in there and they binge accordingly.
But exclusivity carries a cost that never shows up on your dashboard. You cannot build a mailing list of buyers on platforms where you have never sold anything. That gap quietly compounds over several years.
What The Survey Data Says
The 2025 Indie Author Survey from Written Word Media is the closest thing we have to a real headcount.
Here’s the split:
- 38% of authors have everything in KDP Select
- 30% are fully wide
- The rest run a mixed catalog
Now look specifically at the top earners. Among authors making $5,000 a month or more, 43% keep everything in Select, while only 15% are fully wide.
That’s the part people conveniently skip when arguing for wide. At the top of the income table, exclusivity is more common rather than less.
Two honest caveats belong here. First, that’s correlation rather than proof, because high earners may be in Select simply because Select suits high-volume genres, not because Select made them successful. Second, romance is heavily over-represented at the top of that survey: romance authors were 21% of respondents but roughly 44% of those earning $10,000 a month or more, and paranormal romance appeared at approximately 2.5 times its expected share.
So the survey is partly measuring what genre you write, not merely where you publish it.
The Real Lever Isn’t KU vs Wide
Here’s the number from that survey that should genuinely change your week.
Authors earning over $10,000 a month had an average of 18,327 email subscribers, authors in the $5,000 to $10,000 band had about 7,488, and authors under $100 a month had just 902.
Overall, authors with an email list earned roughly 20 times more than authors without one.
That gap is dramatically larger than anything in the KU versus wide debate. If you’re agonising over distribution while your subscriber list sits at 300 people, you are optimising the wrong variable entirely.
Marketing spend tracked the same pattern. Authors earning over $10,000 a month spent around $4,500 monthly on marketing, while the $1,000 to $5,000 band spent around $478.
Newsletter swaps are the free version of that reach. If you want a paid option alongside them, Dark Romance Reads runs promo slots and newsletter features aimed at readers who already search by trope.
When Wide Actually Makes Sense For Dark Romance
Wide isn’t a worse choice — it’s simply a different business with different mechanics.
It makes genuine sense when:
- You have a deep backlist. Wide is a slow build, so three books won’t accomplish much, whereas fifteen might.
- You write series with strong read-through. Kobo and Apple readers reliably buy complete series, and first-in-series free performs well on those stores.
- You sell direct. Direct sales keep upwards of 90% of the cover price and hand you buyer emails, which is the strongest single argument for leaving Select in 2026.
- Your subgenre is under-served outside Amazon. Reduced competition on smaller stores can translate into better merchandising odds.
- You’ve hit a genuine KU ceiling. If page reads have flatlined for six months despite consistent advertising, exclusivity isn’t buying you anything.
It makes considerably less sense when you’re brand new, when your catalog sits under five books, or when your entire advertising strategy is built on Amazon.
A Test You Can Actually Run
Don’t flip the whole catalog at once. Run a controlled experiment instead.
- Pick one complete series that isn’t your newest, ideally three books or more, finished, with a healthy read-through rate.
- Let the Select term expire naturally. Don’t cancel mid-term — uncheck auto-renew and simply wait it out.
- Go wide with that series only. Use a distributor, or upload directly to Kobo, Apple, Barnes & Noble, and Google Play.
- Make book one permafree or 99c for at least the first 90 days, because wide discovery runs on funnels rather than borrows.
- Give it six months minimum. Wide income ramps slowly, so judging it at 60 days will tell you nothing useful.
- Compare like for like. Measure total net revenue per book rather than units, because a wide sale at $4.99 is not the same event as a borrow.
- Add direct sales in month three. Even a simple storefront gives you the buyer emails Amazon will never hand over.
Track everything in a spreadsheet with three columns: month, channel, and net revenue. That’s genuinely all you need, so resist the urge to over-build the tracker.
What I’d Actually Do
If you write dark romance and you’re under ten books, stay in KU and concentrate on building your list. The genre lives there, the borrows are real, and your energy is better spent on the next book and the next thousand subscribers.
If you’re over fifteen books with at least one finished series and a list above 5,000, run the wide test on that single series while keeping your newest releases in KU as you learn.
Whatever you choose, get a direct store running this year. Exclusivity is a decision you can reverse within 90 days, but a buyer list is an asset nobody else can switch off.
Note: KENP rates, fund sizes, and survey figures above come from the linked sources and reflect the periods those sources cover. Amazon does not publish forward guidance, so treat all rates as historical, not predictive.
If you write dark romance, you already know the pain of getting buried next to sweet contemporary releases on generic deal sites. Dark Romance Reads exists so your readers can actually find you — filtered by trope, filtered by trigger, no digging required. We’re currently accepting author submissions for site listings and newsletter features. Come say hi — we’d love to get your books in front of readers who are already looking for exactly what you write.
