KDP royalties: when 70% pays less than 35%
Amazon expanded the 70% royalty band to $2.99–$12.99 on 7 July 2026, lifting a $9.99 ceiling that had stood since 2007 — and most published guidance still quotes the old number. But the more useful finding is the one nobody checks: because Amazon deducts delivery costs from the 70% option and not from the 35% option, the higher rate pays less once your file passes a size you can calculate exactly. That size is your list price divided by 30 cents.

The ceiling moved in July 2026
The single most repeated number in self-publishing advice is that the 70% royalty option runs from $2.99 to $9.99. It does not any more. Amazon's own list price page states that “the maximum list price for the 70% royalty option for eBooks has changed from $9.99 to $12.99 on Amazon.com, with equivalent amounts in other KDP marketplaces”, and dates the change: “Effective July 7, 2026, the 70% royalty option price band is $2.99-$12.99 on Amazon.com, expanding from the previous range of $2.99-$9.99”.
That ceiling had stood since 2007, which is why it is embedded in almost everything written about Kindle pricing, and why a large share of guidance still describes the old band as current.
One detail matters more than the headline: Amazon did not move anybody's price. Existing prices and royalty selections stayed as they were unless the author changed them. So a back-catalogue priced at $9.99 because $10.00 used to be punitive is still sitting there, and the reason it is sitting there has gone.
The floor did not move. Below $2.99 you are on the 35% option regardless, and on that option the minimum depends on file size: under 3 MB you may price from $0.99, from 3–10 MB the minimum is $1.99, and at 10 MB or more it is $2.99.
The one-cent cliff
Because the band has a hard edge, the royalty curve has a step in it rather than a slope. Cross the top of the band by a single cent and you do not lose a little — you drop onto a different rate entirely, and the rate is half the size.
| List price | Option | Royalty per sale (1 MB file) |
|---|---|---|
| $12.99 | 70% | $8.99 |
| $13.00 | 35% | $4.55 |
One cent cuts the royalty by 49%. You would need to sell roughly twice as many copies at $13.00 to match $12.99, which is the opposite of what a price rise is meant to do. The cliff was always there; what changed in July is where it stands. For nineteen years it sat at $10.00, and much of the pricing folklore in this category — price at $9.99, never at $10.99 — is really just authors routing around it.
Read the other way, the change is worth about $2.10 a sale to anyone pinned at the old ceiling: $8.99 at $12.99 against $6.89 at $9.99, on a 1 MB file. Against what $12.99 would have earned under the old rules, at 35%, it is worth about $4.44. Whether your readers will pay $12.99 is a separate question, and one that differs by category.
Our arithmetic on Amazon's published rates, not Amazon figures. Formula and delivery cost below.
When 70% pays less than 35%
This is the part almost no guide gets right, and the reason the two options are not simply the good one and the bad one.
Amazon charges a delivery cost based on file size — “US $0.15/MB” on Amazon.com, with a floor of “US$0.01 for sales in US Dollars” and file sizes “rounded up to the nearest kilobyte”. Crucially, that charge applies to one of the two options. Amazon's royalty page describes the 70% option as “70% of your list price without VAT, less delivery costs”, while the 35% option is simply “35% of your list price without VAT for each unit sold”. Choose 35% and the delivery fee is not charged at all.
So the comparison is not 70 against 35. It is 70% of a reduced amount against 35% of the full amount. Set those equal and it collapses to something simple: the 70% option stops being the better choice exactly where the delivery fee reaches half your list price. At 15 cents a megabyte, that is a break-even file size of your list price divided by 30 cents.
| List price | Break-even file size | 70% royalty at 1 MB | 35% royalty |
|---|---|---|---|
| $2.99 | ~10.0 MB | $1.99 | $1.05 |
| $4.99 | ~16.6 MB | $3.39 | $1.75 |
| $9.99 | ~33.3 MB | $6.89 | $3.50 |
| $12.99 | ~43.3 MB | $8.99 | $4.55 |
For a plain-text novel this is academic: a 300-page manuscript with no images is typically well under 2 MB, and the fee is a rounding error. It stops being academic for illustrated books, cookbooks, photography, workbooks, children's books and anything with embedded fonts or high-resolution diagrams — exactly the categories where authors are told to pick 70% without checking. A 15 MB illustrated book at $2.99 carries $2.25 of delivery, so the 70% option pays $0.52 while the 35% option pays $1.05. Double. The advice to always take 70% costs that author half their income per sale.
There is a second lever, and it is usually the better one: shrink the file. Every megabyte removed is 15 cents back on every copy sold, forever. Compressing that same book from 15 MB to 3 MB takes the royalty from $0.52 to $1.78 — a larger gain than any plausible price change would deliver.
One honest note on the numbers. Several widely-shared guides put these break-even points much lower, around 7 MB at $2.99 or 12 MB at $4.99. Those figures do not reconcile with Amazon's published $0.15/MB: at 7 MB a $2.99 book earns $1.36 on the 70% option against $1.05 on the 35%, so 70% is still ahead by about 31 cents. We show our working above so you can check it against your own file size rather than take either figure on trust.
Break-even derived from Amazon's two published formulas. VAT appears in both and therefore cancels, so the result holds in VAT marketplaces too — though the per-megabyte rate differs by marketplace (Amazon gives Spain as €0.10/MB, and states it deducts no delivery cost at all for sales in yen on books of 10 MB or more).
What you must declare, and to whom
KDP has an AI rule, it is unambiguous, and it is narrower than the anxiety around it. Amazon states: “You are required to inform us of AI-generated content (text, images, or translations) when you publish a new book or make edits to and republish an existing book through KDP.” Three things follow that most summaries miss.
The disclosure goes to Amazon, not to readers. It is a declaration made at upload. Amazon does not add an AI label to the product page, and nothing in the guidelines asks you to put one in your description.
Editing does not launder it. Amazon defines AI-generated content as content “created by an AI-based tool”, counting “even if you applied substantial edits afterwards”. The opposite case: “If you created the content yourself, and used AI-based tools to edit, refine, error-check, or otherwise improve that content… then it is considered ‘AI-assisted’ and not ‘AI-generated’.” The test is who produced the first draft, not how much of it survived.
It applies on every republish, so a back-catalogue title edited today carries the same duty as a new release.
What makes this worth knowing is how little the platforms agree. This site has now read four at source and found four regimes: Amazon wants a private declaration; YouTube requires a public label on realistic synthetic content but exempts cloning your own voice; Spotify publishes no podcast disclosure rule at all, restricting impersonation instead; and ACX does not offer disclosure as an option — its submission requirements prohibit unauthorized AI narration outright. There is no portable answer to “do I have to disclose AI?”, and on at least one Amazon surface the question is not disclosure but permission.
Separately, and unrelated to AI, Amazon caps throughput: “we limit the number of titles you can create at the same time to 10 per book format each week.” If you are drafting with AI writing tools, that is the ceiling on the publish side regardless of how fast you can produce manuscripts.
What Select exclusivity costs
KDP Select is free to join and puts your book into Kindle Unlimited, where you earn from the Global Fund based on pages read. The price is exclusivity, and it is stricter than most descriptions suggest: “Your Kindle eBook must also be exclusive to the Kindle Store for the KDP Select enrollment period”, and “during the 90-day enrollment period, the Kindle eBook can only be distributed through KDP and public libraries.”
Two practical consequences. Other formats are fine — Amazon says “you can continue to distribute print, video, audio, or other formats of your title elsewhere”, so a paperback or audiobook edition is unaffected. And enrollment “is automatically renewed unless you opt out”, making the 90 days a rolling commitment rather than a one-off trial.
This is the decision that collides with the rest of a digital-product business. If your plan is to sell the same ebook through your own storefront — the model priced out in our Gumroad vs Payhip vs Lemon Squeezy comparison — Select forecloses it for as long as you stay enrolled, and because renewal is automatic, staying enrolled is the default rather than a choice you revisit.
There is also a pricing interaction worth knowing before you decline: for sales to customers in Brazil, Japan, Mexico and India, Amazon states books “must also be enrolled in KDP Select to be eligible for the 70% royalty option”. In those four marketplaces, opting out of Select halves your rate.
On Kindle Unlimited earnings, Amazon publishes a mechanism but not a rate. Authors earn a share of a fund whose size Amazon reviews monthly, allocated by share of total pages read, capped at “a maximum of 3,000 Kindle Edition Normalized Pages (KENP) Read per title per customer”. Because both the fund and the total pages read move every month, no per-page figure is fixed in advance, and this page quotes none.
Getting paid
KDP pays “approximately 60 days after the end of the month in which the sale was reported (90 days for Expanded Distribution)”. That is a long tail: a sale made in January is money in your account around the end of March.
The threshold depends on how you take the money. Amazon publishes a minimum of 100 USD for wire transfer and cheque on Amazon.com, with local equivalents elsewhere — 100 GBP, 100 EUR, 100 CAD, 1,000 MXN, 10,000 JPY — and publishes no minimum for direct deposit. Each marketplace accrues separately, which is why a book selling slowly across several territories can sit unpaid in each while the total looks healthy.
Below-threshold balances are safe: Amazon states it will “keep a running total and issue the payment once you met the threshold”. That is not universal. Of the programmes this site has read at source, TikTok is the outlier whose terms allow unpaid balances to expire, while Spotify, Amazon Associates and KDP all accumulate.
Added September 2026 — the tax paperwork starts far lower than the payment does. KDP royalties are reported as royalties rather than as freelance income, and that classification carries its own threshold which the 2026 increase did not touch. Amazon states that “if you exceeded the $10 global royalty payment threshold across all Amazon businesses, your IRS Form 1099-MISC will be issued”, aggregated across every Amazon business and sent by 31 January; for non-US publishers it reports on Form 1042-S instead, at a stated trigger of “the $0.49 global royalty payment threshold”. So a form can arrive for $12 of royalties, or for 49 cents, while the same year’s brand-deal income would need $2,000 before anything is filed. Non-US authors should also note Amazon’s statement that any reduction of the statutory 30% withholding rate “will not apply until you can provide a TIN”. We set all four thresholds against each other in creator tax forms.
What we could not verify
Stated plainly rather than filled in with numbers we could not read at source.
- Any Kindle Unlimited per-page rate. Amazon publishes the mechanism and says it announces the fund monthly in its community forum, but sets no rate in advance. Widely circulated figures of roughly half a cent per page are third-party estimates of past months, not a published rate, and none appears on this page.
- Per-megabyte delivery rates outside the US and Spain. Amazon publishes $0.15/MB for Amazon.com and €0.10/MB for Spain. Every break-even figure in the table above is therefore US-specific. The rule (break-even where delivery equals half the list price) holds in any marketplace; the file size it corresponds to does not.
- Whether direct deposit truly has no minimum — largely resolved, September 2026. We previously reported this as an absence, because Amazon published thresholds for wire and cheque and said nothing about direct deposit. A re-reading found wording that scopes it explicitly: “only wire and check payments must accrue a minimum amount of earned royalties through the sale of your book”. That is an exclusion rather than silence, so we now treat direct deposit as having no minimum to clear — while noting Amazon still never prints a zero. On that reading KDP is the lowest of the six programmes this site has read at source; see how the thresholds compare.
- How Amazon measures your file size for delivery purposes — specifically whether it is the uploaded file or the converted Kindle file. Amazon states only that sizes are rounded up to the nearest kilobyte. Since the converted file is what is delivered, our working assumption is that it is the converted size, but Amazon does not say so on the pages we read.
- Enforcement of the AI disclosure rule. Everything here is published wording. We have not tested how declarations are reviewed, and state no rate of removals or suspensions anywhere.
- Print royalties. This page is about Kindle ebooks only. Paperback and hardcover royalties run on a different formula with printing costs deducted, which we did not read at source this time.
FAQ
What is the maximum price for the 70% KDP royalty option?
On Amazon.com it is now $12.99, not the $9.99 that most guides still quote. Amazon states that the maximum list price for the 70% royalty option for eBooks has changed from $9.99 to $12.99 on Amazon.com, with equivalent amounts in other KDP marketplaces, and that the change took effect on 7 July 2026. The floor is unchanged at $2.99. Amazon also notes that current prices and royalty options stay the same unless you choose to change them, so a book already listed at $9.99 was not moved automatically. Anything priced above $12.99 or below $2.99 falls to the 35% option, where the ceiling is $200.
Can the 35% KDP royalty option pay more than the 70% option?
Yes, and it is a matter of arithmetic rather than opinion. Amazon deducts delivery costs from the 70% option and does not deduct them from the 35% option. Delivery on Amazon.com is charged at $0.15 per megabyte. Setting the two formulas equal shows that the 70% option stops being the better deal at the point where delivery cost reaches half the list price, which works out as a break-even file size of the list price divided by 30 cents. At $2.99 that is about 10 MB, at $4.99 about 17 MB, and at $12.99 about 43 MB. Below those sizes the 70% option wins comfortably. Above them the 35% option pays more, which matters mainly for illustrated books, cookbooks, workbooks and photo-heavy non-fiction.
Do you have to disclose AI-generated content on Amazon KDP?
Yes, but to Amazon rather than to readers, and the distinction Amazon draws is not the one most people expect. KDP states that you are required to inform us of AI-generated content (text, images, or translations) when you publish a new book or make edits to and republish an existing book. Amazon defines AI-generated as content created by an AI-based tool, and says it counts as AI-generated even if you applied substantial edits afterwards. Content you wrote yourself and then used AI to edit, refine or error-check is AI-assisted, which Amazon does not require you to declare. The declaration is made to Amazon at upload; Amazon does not publish an AI label on the product page.
What does KDP Select exclusivity actually require?
That the Kindle edition is sold nowhere else in digital form for the enrollment period. Amazon states that your Kindle eBook must also be exclusive to the Kindle Store for the KDP Select enrollment period, and that during the 90-day enrollment period, the Kindle eBook can only be distributed through KDP and public libraries. Other formats are unaffected: Amazon says you can continue to distribute print, video, audio, or other formats of your title elsewhere. Enrollment renews automatically unless you opt out. The practical consequence is that Select and a Gumroad or Payhip listing of the same ebook cannot coexist, so the choice is not one you can defer.
When does Amazon KDP pay royalties?
Approximately 60 days after the end of the month in which the sale was reported, and 90 days for Expanded Distribution. The threshold depends on how you are paid. Amazon publishes a minimum of 100 USD for wire transfer and cheque on Amazon.com, with local equivalents elsewhere such as 100 GBP, 100 EUR and 10,000 JPY, and publishes no minimum for direct deposit. Balances below a wire or cheque threshold are not lost: Amazon states it will keep a running total and issue the payment once you met the threshold. That puts KDP alongside Spotify and Amazon Associates as programmes where unpaid earnings accumulate, rather than TikTok, whose terms allow below-threshold balances to expire.
What we would actually do
Check your file size before you touch your price. It is the input most authors never look at and the one that compounds on every copy sold: every megabyte costs 15 cents a sale on the 70% option. Compress first, then price. Then take 70% unless the file is genuinely large — above roughly ten megabytes at $2.99, or forty at $12.99 — in which case run both numbers rather than assuming.
And if you have a back-catalogue pinned at $9.99 by a ceiling that no longer exists, that is the cheapest revenue decision available to you this year. Every figure here is a September 2026 snapshot of Amazon's own help pages; the band moved once in nineteen years and then moved again two months ago, so re-check before committing to a pricing strategy.
