Amazon KDP costs $0 to publish. There is no listing fee, no setup fee, and no annual charge. What KDP actually charges you is a cut of every sale — 35% or 70% on ebooks, 50% or 60% on print minus the printing cost, plus a per-megabyte delivery fee on the 70% tier.
So “KDP pricing” is really a question about royalty math, not a price tag. Get the math wrong and you can list a book at $4.99 and take home less than you would at $2.99.
In this breakdown, you’ll get:
- The exact royalty rates, price bands, and the new $12.99 ceiling that took effect July 7, 2026
- The delivery fee nobody budgets for, and how it quietly eats image-heavy books
- KDP’s real printing cost formulas for paperback and hardcover, straight from their tables
- Where KDP genuinely beats every alternative — and where it doesn’t
Every figure below was checked against Amazon’s own KDP help pages as of September 2026 and linked to its source. Amazon changed two royalty rules in the last 15 months, so verify before you set a price.
How Much Does It Cost to Publish on Amazon KDP?
Publishing on Amazon KDP costs nothing upfront. You pay no account fee, no upload fee, no ISBN fee, and no per-title charge. Amazon takes its money as a percentage of each sale instead, which means a book that never sells costs you exactly $0 in KDP fees.
The catch is that “free to publish” is not “free to sell.” Every unit sold carries a deduction, and on print books that deduction is large enough to make some price points unprofitable.
Amazon KDP Ebook Royalty Rates: 35% vs 70%
KDP offers two ebook royalty tiers: 35% and 70%. The 70% tier pays roughly double but comes with a price band, a territory restriction, and a delivery fee. The 35% tier has almost no conditions but pays half.
| 35% option | 70% option | |
|---|---|---|
| US price range | $0.99–$200.00 | $2.99–$12.99 |
| Delivery fee deducted | No | Yes ($0.15/MB in the US) |
| Territories paid at this rate | All | ~40 listed countries only |
| Public domain content allowed | Yes | No |
| Must be 20% below print edition | No | Yes |
Sources: KDP Digital Royalty Options and eBook List Price Requirements.
The formulas Amazon publishes are:
- 35% —
35% × (List Price − VAT) = Royalty - 70% —
70% × (List Price − VAT − Delivery Costs) = Royalty
The $12.99 Ceiling Is New — And It Matters
Effective July 7, 2026, the 70% royalty band on Amazon.com widened from $2.99–$9.99 to $2.99–$12.99. The $9.99 cap had stood since 2007, so this is the single biggest pricing change KDP has made in nearly two decades.
A nonfiction book that genuinely warrants $12.99 no longer has to choose between a fair price and half the royalty. At $12.99 you now earn about $9.05 instead of the $4.55 the old rules forced.
Most third-party royalty calculators still show the $9.99 ceiling. Check the date on anything you read, including this page.
The 35% Minimum Changes With Your File Size
The $0.99 floor on the 35% tier is not universal. Amazon scales the minimum list price to how big your file is:
| Kindle file size | Minimum list price (35% tier) |
|---|---|
| Under 3 MB | $0.99 |
| 3 MB to under 10 MB | $1.99 |
| 10 MB or greater | $2.99 |
A heavily illustrated cookbook cannot be a 99-cent loss leader. The file size decides that for you.
What Is the KDP Delivery Fee?
The KDP delivery fee is a per-megabyte charge Amazon deducts from 70% royalty sales to cover wireless file transmission. On Amazon.com it is $0.15 per MB, with a minimum of $0.01, and it is not deducted on the 35% tier.
Rates vary by marketplace: £0.10/MB on Amazon.co.uk, €0.12/MB across the European stores, AUD $0.15/MB in Australia, and ₹7/MB in India (source). Here is what that does to a $4.99 ebook:
| Book type | File size | Delivery fee | Royalty at $4.99 |
|---|---|---|---|
| Plain text novel | 0.5 MB | $0.08 | $3.44 |
| Nonfiction with charts | 3 MB | $0.45 | $3.18 |
| Illustrated guide | 12 MB | $1.80 | $2.23 |
| Photo-heavy book | 25 MB | $3.75 | $0.87 |
A 25 MB book at $4.99 earns less on the 70% tier than on 35% ($1.75). Run both numbers if your file is large. Compressing images before upload is the cheapest royalty increase available to you — our ebook formatting guide covers how.
KDP Print Royalties: The 50% / 60% Split
Print books on KDP earn 60% of list price minus printing cost when priced at $9.99 or above on Amazon.com, and 50% minus printing cost at $9.98 or below. The formula Amazon publishes is (Royalty rate × list price) − printing costs = royalty.
This tiering arrived in June 2025, when Amazon cut the rate from a flat 60% to 50% for cheap print books (KDP Paperback Royalty). It applies to paperback and hardcover alike.
The effect is a genuine dead zone under $9.99. Watch what happens to a 300-page black-ink paperback, which costs $4.60 to print:
| List price | Rate | Royalty |
|---|---|---|
| $8.99 | 50% | $(0.11) — you lose money |
| $9.98 | 50% | $0.39 |
| $9.99 | 60% | $1.39 |
| $12.99 | 60% | $3.19 |
| $14.99 | 60% | $4.39 |
One cent of list price is worth a dollar of royalty. Pricing a 300-page paperback at $9.98 instead of $9.99 costs you exactly $1.00 per copy. There is almost never a reason to price a print book just below the threshold.
Amazon enforces a floor here too: it calculates a minimum list price from printing cost ÷ royalty rate and refuses anything lower, so you cannot accidentally sell below cost.
Expanded Distribution Pays 40%
Paperbacks pushed through Expanded Distribution — reaching bookstores, libraries, and other online retailers via Ingram — earn 40% of list price minus printing cost, flat, with no tiering. Hardcovers are not eligible for Expanded Distribution at all.
That 20-point gap is why many authors run KDP for Amazon and a separate channel for everyone else. Our IngramSpark vs KDP comparison works through when splitting is worth the extra admin.
KDP Printing Cost Formulas (US Marketplace)
KDP calculates printing cost as fixed cost + (page count × per-page cost). Short books fall into a flat fixed-cost tier with no per-page charge at all.
Paperback, Amazon.com (official table):
| Ink & trim | Pages | Fixed | Per page |
|---|---|---|---|
| Black, regular trim | 24–110 | $2.30 | none |
| Black, large trim | 24–110 | $2.84 | none |
| Black, regular trim | 110–828 | $1.00 | $0.012 |
| Black, large trim | 110–828 | $1.00 | $0.017 |
| Standard color, regular | 72–600 | $1.00 | $0.0255 |
| Premium color, regular | 42–828 | $1.00 | $0.065 |
| Premium color, large | 42–828 | $1.00 | $0.080 |
Hardcover, Amazon.com (official table):
| Ink & trim | Pages | Fixed | Per page |
|---|---|---|---|
| Black, regular trim | 75–108 | $6.80 | none |
| Black, regular trim | 110–550 | $5.65 | $0.012 |
| Black, large trim | 110–550 | $5.65 | $0.017 |
| Premium color, regular | 75–550 | $5.65 | $0.065 |
“Large trim” means wider than 6.12 inches or taller than 9 inches. Hardcovers require a 75-page minimum.
Two things fall out of these tables. The per-page cost is identical for paperback and hardcover — the entire hardcover premium sits in the $5.65 fixed cost. And premium color is brutal: a 200-page color paperback costs $14.00 to print versus $3.40 in black ink. Standard color at $0.0255/page is the middle option most illustrated nonfiction should be using.
How Much Does KDP Pay Per Page Read?
KDP pays roughly $0.0042 to $0.0049 per page read through Kindle Unlimited, which works out to about $1.30–$1.45 for a full read of a 300-page book. The exact rate floats every month and Amazon never publishes it as a headline figure.
The mechanism: Amazon sets a monthly KDP Select Global Fund, then divides it across every KENP page read that month across all enrolled titles. The fund reached $66.9 million in May 2026 (Written Word Media’s payout tracker), but a bigger fund does not guarantee a better rate — if pages read grow faster than the fund, the per-page rate falls.
Entering KDP Select requires 90-day digital exclusivity: no Apple Books, no Kobo, no other ebook store for the term. Whether that trade pays depends on genre — romance and thriller readers live in Kindle Unlimited, most business nonfiction does not. How much is Kindle Unlimited covers the reader side.
What KDP Doesn’t Charge You For
The “Amazon takes everything” framing gets repeated a lot, and it isn’t accurate. KDP charges nothing for:
- ISBNs — free for KDP distribution, where Bowker charges about $125 for a single number
- Storage and hosting — no fee, forever
- Unsold print inventory — print-on-demand means you never pay for stock
- Republishing — upload a corrected file as many times as you like
- Cover creator and previewer — included
The one thing worth paying for separately is your own ISBN, if you want an imprint name rather than “Independently published” on the listing. Do you need an ISBN for Kindle walks through that decision.
Where Amazon KDP Beats Chapter
Chapter and KDP do different jobs — Chapter writes the book, KDP publishes and sells it — so this isn’t really a versus. But KDP has advantages Chapter has no answer to, and pretending otherwise would be useless to you.
KDP owns the demand. Amazon is where book buyers already are. No writing tool creates readers. KDP puts your title in front of an audience that is already shopping, and that beats any feature on any manuscript tool.
KDP is genuinely free. $0 to publish, $0 to stay published. Chapter costs $97. If you already have a finished manuscript, KDP is the only thing in this workflow you need.
KDP handles everything after the file. Global distribution, payment processing, tax forms, returns, Kindle Unlimited, and print-on-demand fulfilment across eleven marketplaces — infrastructure worth billions, priced as a royalty percentage.
If your problem is “how do I sell a book,” KDP is the answer and nothing here changes that.
Where Chapter Fits
Our Product — Chapter
Chapter is an AI book writing platform that produces a complete, publication-ready manuscript — then you upload it to KDP. It solves the step before KDP, not the same step.
The honest framing: KDP’s royalty math only matters if a manuscript exists. Most people who research KDP pricing never publish anything, because the book never gets written. That is the problem Chapter exists for.
Best for: authors with a book in their head and no finished draft Pricing: $97 one-time, includes one book credit and lifetime access — extra credits from $47, full breakdown here Why we built it: the gap between “I should write a book” and “I have a file to upload” is where nearly every author stalls
Chapter has written manuscripts for 2,147+ authors across 5,000+ books, and has been covered in USA Today and the New York Times. One author reported $13,200 from a single book; another $60K in 48 hours.
Run it against KDP’s own tables: at $12.99 on the 70% tier, a modest ebook earns about $9.05 per copy, so eleven sales covers the $97. KDP’s cut is identical whether you spent six months writing or one afternoon generating.
Where Chapter is not the right buy: if your manuscript is already finished, skip it and put the $97 into a cover designer.
What KDP Pricing Actually Costs You: Worked Example
Take a 250-page nonfiction book, 2 MB ebook file, published in both formats:
| Format | List price | Deductions | Your royalty |
|---|---|---|---|
| Kindle (70%) | $9.99 | $0.30 delivery | $6.79 |
| Kindle (70%) | $12.99 | $0.30 delivery | $8.88 |
| Paperback | $16.99 | $4.00 print, 60% | $6.19 |
| Hardcover | $26.99 | $8.65 print, 60% | $7.54 |
| Kindle Unlimited | — | ~330 KENP | ~$1.50 |
The ebook at $12.99 is your best single unit. The paperback trails it at nearly double the list price, because printing cost is real money. And a full Kindle Unlimited read pays about a sixth of a sale — only a good deal if it drives six times the volume.

FAQ
Is Amazon KDP free to use?
Yes, Amazon KDP is completely free to use. There is no account fee, no upload fee, and no per-title charge. Amazon earns its money by taking a royalty percentage of each sale instead — 35% or 70% on ebooks, and 50% or 60% minus printing cost on print books.
What is the best royalty option on KDP?
The best royalty option on KDP is the 70% tier for most ebooks priced between $2.99 and $12.99. It pays roughly double the 35% rate. The exception is large files — the two tiers break even when your file size in MB is about 3.3× your list price, so a 20 MB book priced at $4.99 earns more on 35%.
Why did my KDP paperback royalty drop to 50%?
Your KDP paperback royalty dropped to 50% because Amazon tiered print royalties in June 2025. Books listed at $9.98 or below on Amazon.com now earn 50% instead of 60%, both minus printing cost. Raising your list price to $9.99 restores the 60% rate.
How much does KDP pay per book sold?
KDP pays 35% or 70% of the ebook list price minus delivery fees, or 50% to 60% of a print book’s list price minus printing cost. A $9.99 Kindle ebook on the 70% tier typically pays about $6.80. A $16.99 paperback at 250 pages pays about $6.20.
Is KDP Select worth the exclusivity?
KDP Select is worth the exclusivity for genre fiction and not much else. It requires 90 days of digital exclusivity in exchange for Kindle Unlimited page reads at roughly $0.0045 per page. Romance, thriller, and fantasy readers concentrate in KU; most nonfiction audiences do not.
