Most self-published authors price a book, see 70% or 60% royalty, and assume that’s the cut they keep.
It rarely is. The rate on the page is a ceiling, not your take-home.
What you actually keep is that number minus a delivery fee or a printing cost — on every single sale.
Delivery fees shrink Kindle earnings. Printing costs shrink paperback and hardcover margins.
One rule changed in July 2026. The 70% Kindle band now tops out at $12.99, not $9.99.
Most pages still quoting the old ceiling are out of date.
This guide shows what each format really pays, with a KDP royalty calculator to run your own numbers before you publish.
KDP Royalty Calculator: Plug In Your Book
Enter the price you’re actually considering, then match the format inputs to the version you’ll publish.
Compare the net royalty each format returns, not the headline percentage.
Amazon.com (USD) estimates using current KDP rates: eBook 70% ($2.99–$12.99 since 7 July 2026, minus a $0.15/MB delivery fee) or 35%; print 60% at $9.99+ or 50% at $9.98 and below, minus printing cost (black-ink paperback $2.30 flat to 110 pages, then $1.00 + $0.012/page; premium color $1.00 + $0.065/page; hardcover $6.80 flat to 108 pages, then $5.65 + $0.012/page). Figures vary by marketplace — confirm in your KDP dashboard before publishing.
If one format pays badly, don’t panic. Adjust an input, rerun it, and price from the take-home number.
The breakdown underneath shows where each deduction lands, so the take-home number is never a mystery.
Switch the tabs to see how the same book pays as a Kindle eBook, a paperback, and a hardcover.
How We Verified These Numbers
Every rate in the calculator comes from Amazon’s own documentation, not third-party estimates.
eBook rates and the delivery fee come from KDP’s royalty terms. The $2.99–$12.99 band comes from the list-price requirements.
Print rates come from the paperback royalty page, printing costs from the printing-cost tables, and page reads from the Kindle Unlimited rules.
Every figure was rechecked against those pages on 8 August 2026 and reflects the Amazon.com (US) marketplace.
Two of Amazon’s numbers moved in 2025 and 2026. The sections below use the current ones.
Printing and delivery costs vary by marketplace, so your exact royalty always appears on KDP’s own pricing page when you publish.

- How the delivery fee changes your rate: the hidden cost that quietly trims your 70% Kindle royalty — and the price point where 35% actually wins.
- Why the headline rate misleads: the royalty percentage on the page tells you almost nothing about what you’ll actually deposit.
- What drives your printing cost: the production variables that decide whether your paperback or hardcover earns or loses money per sale.
- The $2.99–$12.99 eligibility band: the boundary Amazon moved in July 2026, and the reason a price you rejected last year may now qualify.
- Kindle Unlimited vs unit sales: the page-read income stream that changes the whole calculation for passive income authors who ignore it.
How KDP Royalties Actually Work Across the Three Formats
KDP royalties follow one pattern across Kindle, paperback, and hardcover. Amazon starts with a headline rate, then subtracts the cost of delivering or printing the book.
Treat KDP royalties as an equation, not a promise.
Every royalty deal has that shape. If you want the general version, how royalties work covers licensing outside Amazon.
For Kindle eBooks, Amazon applies either 70% or 35%. The 70% option then subtracts a delivery fee based on your file size, per KDP’s royalty page.
Heavy images, charts, or complex formatting push that fee up.
A 300-page novel might sit at 1–2 MB; a photo-heavy cookbook can hit 30 MB or more.
Print works differently.
Print pays on a two-tier rate: 60% at a list price of $9.99 or higher, 50% at $9.98 or below, per the paperback royalty page.
Then Amazon removes the printing cost, set by page count, ink, and trim. A long paperback can show 60% on paper and still net almost nothing.
Self-publishing is one of the few genuinely scalable online income models, but only if you price from net royalty, not the headline percentage.
70% or 35%? When the Lower Rate Actually Pays More
The 35% rate sometimes beats 70%. It comes down to price and file size.
Below $2.99 or above $12.99, the 70% tier isn’t an option, per KDP’s list-price rules.
The new ceiling is opt-in. A book already priced at $10.99 stays on 35% until you change it yourself.
Inside that band, the $0.15-per-MB delivery fee decides it.
A lean text file barely feels it; a 40 MB illustrated book can lose more to the fee than it gains from the higher rate.
Set the two formulas against each other and a clean rule falls out.
The 70% option wins whenever your file size in MB sits under roughly 3.3× your list price in dollars.
At $4.99 that break-even is about 16 MB. At $12.99 it stretches to about 43 MB.
Amazon publishes both formulas but never the crossover. It only shows up once you set them equal.
Don’t default to 70%.
Run both rates against your real price and file size, and keep the larger number.
That one decision can swing your per-sale royalty by a dollar or more.
Paperback and Hardcover: Why 60% Royalty Isn’t 60% of the Price
KDP’s print royalty is a starting line, not your payout.
Your page count, ink, and trim create the printing cost Amazon subtracts before you see a cent, per the printing-cost page.
That cost also sets the minimum list price your book needs just to earn a positive royalty.
The chain runs list price → royalty rate → minus printing cost → what lands in your account.
Printing Costs by Page Count, Ink, and Trim Size
Three levers move your print cost, all set out in Amazon’s printing-cost tables.
- Pages: black ink is $2.30 flat to 110 pages, then $1.00 + $0.012 a page.
- Ink: premium color runs $0.065 a page, standard color $0.0255, black ink $0.012.
- Trim: large trims lift black ink to $0.017 a page, and hardcover carries a $5.65 fixed cost.
A 300-page black-ink paperback costs $4.60 to print. The same book at $19.99 nets $7.39 per sale.
Switch that interior to premium color and the cost hits $20.50, wiping the royalty out entirely.
Standard color sits between the two at $8.65 for the same 300 pages.
Lock page count, ink, and trim first. Then the royalty number stops pretending.
The Minimum List Price Your Print Book Needs
Print pricing starts with paper, not profit.
Your list price has to cover the printing cost, or KDP won’t let you publish at that price, per the minimum-price rule.
The formula is simple: printing cost ÷ royalty rate = your floor.
| Black-ink paperback | Printing cost | Minimum list price |
|---|---|---|
| 150 pages | ~$2.80 | ~$5.60 |
| 300 pages | ~$4.60 | ~$9.20 |
| 500 pages | ~$7.00 | ~$11.67 |
The jump at 500 pages happens in two steps.
Dividing by 50% gives $14.00, which clears $9.99 — so the 60% rate applies instead and the floor lands at $11.67.
Run your real page count through the calculator above to see your own floor in seconds.
Kindle Unlimited vs Sales: Which Earns You More Per Book
Enroll in KDP Select and Kindle Unlimited pays you per page read instead of per sale.
That money comes from a monthly Global Fund, divided by every page read across the platform, per the Kindle Unlimited rules.
Amazon publishes the size of that fund, never a per-page rate. Authors only see theirs after the fact.
In the US it has landed near half a cent a page in recent months, and each reader counts for at most 3,000 pages per title.
KENP isn’t your manuscript page count — Amazon normalizes it, and it usually runs higher.
Romance and series readers tend to finish books, which is why those genres lean hardest on page reads.
A book running 300 KENP and read to the end earns roughly $1.25 to $1.45 — sometimes more than a discounted sale, sometimes less.
What the Income Data Says About Page Reads
The Authors Guild’s survey found Kindle Unlimited “particularly effective for self-published authors, who earned 67 percent more book income from the platform than traditionally published authors make on book-earnings alone.”
Authors Guild CEO Mary Rasenberger said the survey “paints a sobering picture of the financial realities authors face today.”
A newer Authors Guild study from June 2026 found only 6% of books read in the previous month reached readers through a subscription like Kindle Unlimited.
Set those two findings side by side and the picture sharpens.
Page reads pay self-published authors well per book, but reach a thin slice of readers.
So treat Kindle Unlimited as a channel to price for, not a plan to lean on.
Book royalties are one stream of several. How authors make money sorts the rest by what you own.
The real question isn’t which platform is better. It’s whether your book earns more when one reader buys it, or when one reader finishes it.
Length and completion decide.
How to Grow What Each Book Actually Earns You
Once the calculator shows your per-book number, two levers grow it: keep more per sale, and sell more copies.
Keep more per sale.
Amazon takes its cut on every order, but a book or bonus sold direct can keep nearly the whole price.
A one-time checkout tool like ThriveCart lets you sell the same PDF or bundle from your own page for a single $495 payment, with 0% taken on sales.
Sell more copies.
Launch-week sales drive your Amazon ranking, and that spike comes from an audience you can email on release day.
An email platform like Kit holds your reader list and turns a launch into concentrated sales — it’s free up to 10,000 subscribers.
A newsletter on Beehiiv grows that audience between books, so every release lands in front of warm buyers.
The math is simple: royalty per copy × warm buyers. Same manuscript, better format mix, bigger first week.
If print is your lever, a print-on-demand workflow keeps inventory at zero while the royalty math above still applies.
Pricing checked against each platform’s own page on 8 August 2026.
Kit’s pricing page shows free to 10,000 subscribers, then $33/mo billed yearly. On beehiiv’s pricing page it’s free to 2,500, then $43/mo.
ThriveCart’s lifetime licence is $495 once, with 0% taken on sales. A $47/mo plan is now its headline offer.
Frequently Asked Questions
Does Amazon Subtract Taxes Before Paying KDP Royalties?
It can. Amazon may withhold tax before paying, depending on your country and treaty status.
Complete the KDP tax interview first — it sets your withholding rate.
US-based authors usually have income reported rather than withheld. Non-US authors face withholding on US-source royalties unless a treaty lowers it.
How Often Does Amazon KDP Pay Author Royalties?
KDP pays monthly, about 60 days after the end of the month a sale is reported, per KDP’s payment terms.
Expanded Distribution runs on a 90-day lag instead.
Earn royalties in January and payment lands near the end of March.
Direct deposit has no minimum. Wire and cheque payments need $100 to accrue first.
Track sales by month, not by launch week, and plan your cash flow around that delay.
Do KDP Royalties Change by Country or Marketplace?
Yes. VAT, delivery fees, list-price rules, and royalty eligibility all vary by marketplace, per KDP’s royalty page.
A Kindle book at $4.99 in the US won’t net the same as the equivalent sale in the UK, Germany, or Japan.
Check each marketplace individually to see your real per-sale royalty.
Are Refunds Deducted From My KDP Royalty Payments?
Yes. Amazon deducts refunded orders from your royalty payments.
A returned eBook or reversed print sale shows up as a negative adjustment in your dashboard.
Treat every royalty figure as gross before returns, and leave room for refunds and promotions when you price.
Can I Change My Book Price After Publishing?
Yes — open your KDP Bookshelf, edit pricing, update the list price, and republish.
Check the royalty impact first.
A small change can flip you from 70% to 35% on Kindle, or shift your print profit after costs.
Amazon applies the new price within 72 hours, per KDP’s published timelines.
Conclusion
The gap between the headline rate and your real royalty is the whole game.
A $2.99 Kindle book at the 70% rate starts at about $2.09 — before the delivery fee trims it further, per KDP’s own math.
The ceiling moved to $12.99 in July 2026, so a price you ruled out last year may pay differently now.
So run your price, page count, and file size through the calculator above, then pick the format and rate that nets the most.
Then point that book at readers. For the next layer, building an audience is how you turn a per-book royalty into launch-week income.
