Why this matters
Almost every beginner KDP figure circulating online is either out of date or was never sourced. The print royalty rate changed, printing costs are a formula rather than a number, and Amazon's definition of a low-content book excludes several things people routinely call low-content. Getting the classification and the arithmetic right first is what stops you designing a book whose price can never work.
What KDP is, precisely
Kindle Direct Publishing is Amazon's self-publishing platform. You can publish Kindle eBooks, paperbacks and hardcovers, and your book is distributed through Amazon marketplaces. Print books are print-on-demand: Amazon prints each copy when a customer orders it. Amazon states that it subtracts printing costs from your royalties, so you don't pay printing costs upfront or carry inventory. That is genuinely the appealing part of the model.
Classify your book the way Amazon does
This matters more than it sounds, because the classification carries real restrictions and one checkbox decides whether your book is accepted.
Amazon's own examples
| Low-content | Not generally low-content |
|---|---|
| Notebooks | Novels |
| Planners | Nonfiction |
| Diaries and journals | Puzzle books |
| Prompt journals | Coloring books |
| Log books (habit, activity, gratitude) | Photography |
| Coupon books | Sheet music |
| Score card templates | Manuals |
| Crafting templates | Textbooks |
| Blank sheet music | Children's books |
What a print sale actually pays
Print royalty
(royalty rate × list price) − printing cost = royalty
The rate is 50% or 60% depending on your list price and marketplace, or 40% through Expanded Distribution. Amazon's own worked example: a $15 list price on a 333-page regular-trim black-ink paperback in the US gives (0.60 × $15) − $5.00 = $4.00.
What a Kindle sale pays
Kindle eBooks work differently — there is no printing cost, but there are two royalty options and the higher one has conditions attached.
The two Kindle options
| 35% option | 70% option | |
|---|---|---|
| Formula | 35% × (list price − VAT) | 70% × (list price − VAT − delivery costs) |
| Delivery costs | Not deducted | File size in MB × per-MB rate |
| Territories | Any territory | Only Amazon's listed Available Sales Territories |
About the "passive income" framing
A published book can sell without further work from you, and that is a real property of the model worth understanding. What can't be supported is anything about how much. There is no authoritative source for typical KDP sales volumes, typical earnings, or how many titles produce a given income — and the figures that circulate are not traceable to Amazon or anyone else with the data.

Worked example
What the $9.99 threshold is worth on one journal
A 120-page black-ink paperback journal, 6 × 9 in regular trim, sold on Amazon.com. Printing cost calculated from Amazon's formula: $1.00 fixed + (120 × $0.012) = $2.44.
| Line | Value | Note |
|---|---|---|
| Printing cost | $2.44 | $1.00 + (120 × $0.012) |
| At $6.99 — rate is 50% | $1.06 | (0.50 × $6.99) − $2.44 |
| At $8.99 — rate is 50% | $2.06 | (0.50 × $8.99) − $2.44 |
| At $9.98 — still 50% | $2.55 | The last price in the lower band |
| At $9.99 — rate becomes 60% | $3.55 | (0.60 × $9.99) − $2.44 |
| Gain from one cent | +$1.00 | $9.98 to $9.99 |
| Minimum list price in the 50% band | $4.88 | $2.44 ÷ 0.50 |
Raising the price from $9.98 to $9.99 — one cent — increases the royalty per copy from $2.55 to $3.55.
This is why a flat "60% minus printing" is a costly thing to believe. A seller who prices at $8.99 because it looks friendlier than $9.99 is giving up about $1.49 per copy, and the difference isn't the dollar of price — it's the ten points of rate. Check which side of the threshold your marketplace uses before you settle on a price.

Do it with your own numbers
Calculate what one sale of your book pays
Before you start, have ready
- Your book concept, classified as low-content or not using Amazon's test
- Intended format — Kindle eBook, paperback or hardcover
- An intended trim size and a realistic page count
- Ink choice: black, standard colour or premium colour
- The list price comparable books are charging
Open the KDP Royalty Calculator
You will produce: Royalty per copy at your intended price, and what happens either side of your marketplace's royalty threshold.
Then ask yourself: Test at least three prices, including one just below and one just above the threshold for your marketplace. If the price that clears a worthwhile royalty is far above what comparable books charge, that is your go or no-go signal — and the fix is usually fewer pages or a different ink choice rather than a higher price.
Common mistakes
Assuming a flat 60% print royalty
The rate is 50% or 60% depending on list price and marketplace. At a low price the real rate is 50%, and the arithmetic built on 60% is wrong by a wide margin.
Instead: Check which side of your marketplace's threshold your price sits on before calculating anything.
Using a remembered printing cost
Printing cost is a formula whose inputs are trim size, page count, ink, paper and marketplace. A single quoted figure can't be right for your book.
Instead: Calculate fixed cost + (page count × per-page cost) for your actual specification, or use KDP's own printing cost and royalty calculator.
Calling a coloring or puzzle book low-content
Amazon's definition turns on repetitive interior pages designed to be filled in, and it explicitly excludes activity books. Mis-classifying gets a book rejected.
Instead: Apply Amazon's own test, and check the examples table before ticking any box.
Expecting a free ISBN on a low-content book
Low-content books aren't eligible for the free KDP ISBN, and the choice can't be changed after publishing without unpublishing.
Instead: Decide deliberately between your own ISBN and no ISBN, knowing that no ISBN also means no Read Sample.
Reading "70% royalty" as keeping 70%
VAT and delivery costs come out first, the option has territory and pricing conditions, and several situations silently drop a sale to 35%.
Instead: Read the conditions, check the current price band on KDP's own page, and calculate with delivery cost included.
Designing before doing this arithmetic
A page count and ink choice you've already committed to may make a viable price impossible. That's expensive to discover after the design work.
Instead: Calculate the royalty at a plausible price first, then design to the specification that supports it.
Illustrative Beginner Scenario
Renee, first journal
- Situation
- Renee planned a 120-page gratitude journal and had read that KDP pays 60% minus printing. She picked $8.99 as a friendly price and expected about $3.15 a copy.
- What went wrong
- At $8.99 on Amazon.com the rate is 50%, not 60%. Her actual royalty was $2.06 — about a third less than she expected — and she had budgeted her design time against the wrong figure.
- What changed
- Working through the royalty calculator, she found the threshold at $9.99 and tested either side of it. She also checked Amazon's low-content page and confirmed a prompt journal does qualify, which told her she'd need to decide about an ISBN and that buyers wouldn't be able to look inside without one.
- Result
- She priced at $9.99 for a royalty of $3.55, and went into the design lesson knowing her page count and ink choice were now decisions with a price attached. Whether the journal sells is a separate question she still has to answer.
- Lesson
- The most expensive KDP mistakes happen before anything is designed, because they're arithmetic mistakes carried forward. Check the rate that actually applies to your price.
This is a composite teaching example, not a guaranteed result.
Try it yourself
Classify, cost and decide
- Write down one specific book concept in a sentence: who it's for and what the interior pages are.
- Apply Amazon's low-content test — minimal or no interior content, generally repetitive, designed to be filled in — and check the examples table. Write down the classification.
- If it's low-content, note what that costs you: no free ISBN, no Expanded Distribution, no series, and no Read Sample without your own ISBN.
- Choose a format and a plausible trim size, page count and ink type.
- Calculate your printing cost with the formula, then your royalty at three prices including one either side of your marketplace's threshold.
- Write a go or no-go sentence: at the price the market supports, does the royalty justify the work?
You end up with: A classified book concept with a format, an illustrative list price, a calculated royalty per copy, and a written economics decision.
Confidence check
Before designing anything, check you can answer these:
- Can you state the two print royalty rates and what decides which one applies?
- Can you calculate a printing cost from page count and ink type?
- Do you know why a coloring book isn't a low-content book?
- Can you name three things the low-content classification takes away?
- Can you explain why "70% royalty" doesn't mean keeping 70%?
- Have you written a go or no-go decision based on your own numbers?
Your next small step · 10 minutes
Calculate your printing cost from the formula, then your royalty at one price either side of your marketplace's royalty threshold.
It replaces the most commonly repeated wrong number in self-publishing with your own, and it sets the page count and ink budget you'll design to in the next lesson.

Questions people ask
Does KDP pay a 60% royalty on paperbacks?
Not always. KDP pays either 50% or 60% on paperbacks sold on Amazon marketplaces, decided by your list price. On Amazon.com the rate is 50% at or below $9.98 and 60% at or above $9.99, with different thresholds in other marketplaces. Printing cost is then subtracted from your share. Expanded Distribution pays 40% minus printing.
How much does KDP charge to print a book?
There's no single figure — it's a formula: fixed cost + (page count × per-page cost), where the values depend on trim size, page count, ink type, paper type and marketplace. On Amazon.com with black ink and regular trim, books of 24–110 pages cost a flat $2.30, while 110–828 pages cost $1.00 plus $0.012 per page. Colour costs considerably more and has two different options.
Is a coloring book a low-content book on KDP?
No. Amazon defines a low-content book as having minimal or no interior content, being generally repetitive, and designed to be filled in by the user — and states this does not typically include activity books such as puzzle books or coloring books. Amazon's own examples list puts coloring books and puzzle books in the not-generally-low-content column.
Do low-content books get a free ISBN?
No. Low-content books don't require an ISBN and aren't eligible for the free KDP ISBN. You either use your own ISBN or publish without one, and the choice can't be changed after publishing without unpublishing and republishing. Publishing without an ISBN also means the Read Sample feature and back cover thumbnail aren't supported.
What price range gets the 70% Kindle royalty?
On Amazon.com the 70% option is available for list prices from $2.99 to $12.99, a band expanded from $2.99–$9.99 effective 7 July 2026, with equivalent changes in other marketplaces. A lot of published advice still quotes the old $9.99 ceiling. Being inside the band is necessary but not sufficient: the eBook must also be priced at least 20% below any physical edition, public-domain books are 35% only, sales outside Amazon's listed territories fall back to 35%, and delivery costs are deducted before the percentage is applied.
Does publishing on KDP really cost nothing?
Uploading and publishing through KDP costs nothing, and Amazon subtracts printing costs from royalties rather than charging you upfront. That is a statement about printing, not about making a book — editing, cover design, proof copies, software, your own ISBN if you buy one, and advertising are all real costs depending on how you choose to work.
