Amazon KDP Keywords, Pricing & Royalties: A Beginner’s Guide for 2026

If you are publishing your first book through Amazon KDP, three things can cause unnecessary confusion: what keywords to enter, what price to set, and how much of that price you will actually receive as a royalty.

My practical advice is to treat these as three separate decisions. Keywords help Amazon understand what readers may be searching for. Your price determines what the customer pays and, together with the format and applicable royalty option, affects what you earn. Your royalty is not the same thing as your book’s selling price. For a paperback, printing costs are deducted from the applicable royalty calculation. For an eligible Kindle eBook on the 70% royalty option, delivery costs can also affect the calculation.

There is also an important 2026 change beginners should know about. Amazon expanded the US Kindle eBook 70% royalty price range from $2.99–$9.99 to $2.99–$12.99, effective July 7, 2026. That gives authors more room when deciding how to price an eligible eBook.

I have been publishing books on Amazon since 2017, and after working through the process repeatedly, I have learned that these decisions become much easier when you stop looking for a magic keyword, a universal book price or one royalty percentage that applies to everything.

Here is how I approach them.

If you are still at the beginning of the process, I have already documented the wider process in my complete guide to publishing your first book. This article is narrower. I am concentrating specifically on the three decisions that affect your Amazon listing and its economics: keywords, pricing and royalties.

When I was starting out, it was easy to look at a book on Amazon and think:

“This book is selling for $9.99, so perhaps I should price mine at $9.99.”

That is not enough information.

Two books can have the same selling price and produce very different royalties.

The same thing happens with keywords.

An author sees a popular search phrase and thinks:

“I need to put this keyword into my KDP account.”

But the better question is:

“Is this actually how my reader would search for the subject of my book?”

That change in thinking makes a difference.

How I Choose Amazon KDP Keywords

KDP currently gives authors up to seven keyword fields for a book. Amazon recommends using relevant words or short phrases that accurately describe the book and reflect how customers may search for it.

That sounds simple.

In practice, this is where many new authors overcomplicate things.

I Don’t Try to Fill Seven Boxes With the Same Keyword

Suppose I have written a Christian prayer book about overcoming fear.

I would not use all seven boxes simply to repeat variations of:

• Christian prayer
• Christian prayers
• prayer book
• prayer for fear
• prayers against fear
• Christian prayer book
• powerful Christian prayers

That gives me seven boxes, but not necessarily seven useful pieces of information.

I want the seven fields to help describe the different ways the intended reader might look for the subject.

Depending on the actual contents of the book, I might investigate phrases around:

• prayers for overcoming fear
• spiritual warfare prayers
• prayers for peace of mind
• Christian prayers for anxiety
• biblical prayers for protection
• prayer against fear
• prayers for a troubled mind

The exact keywords would depend on the actual manuscript.

That last part matters.

I don’t choose keywords first and then try to make the book fit them.

The book comes first.

I Start With the Reader, Not a Keyword Tool

One practical lesson I have learned from publishing multiple books is that keyword research can become a distraction.

You can spend hours collecting hundreds of possible phrases.

But KDP gives you seven keyword fields.

So I start much closer to the book.

I ask:

What is this book actually about?

Then:

What problem is the reader trying to solve?

Then:

What words would that reader type into Amazon?

Amazon itself recommends thinking like a reader and using relevant keywords that accurately describe the content.

For me, that is more useful than trying to sound clever.

---

How I Test a KDP Keyword Before Using It

Before I enter a keyword, I search it on Amazon.

This is one of the simplest checks you can make.

If I am considering a phrase such as:

prayers for overcoming fear

I type it into Amazon and look at the suggestions that appear.

Then I look at the books being returned.

Are they actually about the same subject?

Would a person searching that phrase reasonably expect to find my book?

If the results are completely unrelated, I reconsider the keyword.

This is also where I avoid a common beginner mistake: choosing a keyword simply because it sounds popular.

Relevance matters more than wishful thinking.

If my book is about Christian prayer, I don’t want a keyword that attracts people looking for something completely different simply because I think it might produce more impressions.

That creates the wrong audience.

---

What I Don’t Put in KDP Keyword Fields

Amazon has specific restrictions on keywords.

For example, Amazon says authors should avoid:

• misleading keywords
• other authors’ names
• unrelated books
• subjective claims such as “best book”
• promotional phrases
• temporary statements such as “new” or “on sale”
• words already covered elsewhere in metadata
• Amazon program names such as “Kindle Unlimited” or “KDP Select”
• irrelevant terms

Keywords should accurately describe the book’s content.

So I don’t treat the seven keyword fields as seven advertising spaces.

They are there to describe the book.

That distinction is important.

Don’t Stuff the Keyword Field

You may see advice telling authors to put as many related words as possible into a keyword box.

I would not approach it that way.

Think about what a human reader would type.

That usually produces better metadata than trying to manipulate the search system.

---

Pricing Is a Separate Decision

Pricing is where I see another common mistake.

Authors often ask:

“What is the best price for my book?”

There isn’t one universal answer.

I don’t price a book simply because another author is charging that amount.

Before choosing a price, I look at the format, length, subject, comparable books, production economics and the reader I am trying to reach.

Then I check what that price actually produces in royalties.

That last step is important.

A price can look attractive until you see the royalty attached to it.

Current Kindle eBook Pricing

For Kindle eBooks, KDP offers two royalty options:

• 35%
• 70%

The 70% option has eligibility requirements and applies only in the territories covered by Amazon’s rules. For eligible sales, Amazon calculates the 70% royalty after applicable taxes and delivery costs.

There is a significant 2026 change here.

For Amazon.com, the 70% royalty option now covers eBooks priced from $2.99 through $12.99.

That means an author who previously thought:

“If I go above $9.99, I lose the 70% option.”

needs to update that assumption for 2026.

The maximum is now $12.99 on Amazon.com, subject to the applicable KDP requirements.

But Don’t Price at $12.99 Just Because You Can

This is where I separate the KDP rule from the publishing decision.

Amazon tells me what prices qualify for a royalty option.

It does not tell me what price my particular reader will be willing to pay.

Those are different questions.

If I have a short devotional, a small prayer book and a 300-page specialist nonfiction book, I would not automatically give all three the same price.

The reader needs to see value in the price.

And I need to understand what the price produces after the relevant KDP deductions.

---

A Simple eBook Royalty Example

Suppose an eligible Kindle eBook is priced at:

$4.99

Under the 70% calculation, before applicable taxes and delivery costs:

$4.99 × 70% = $3.493

If a $0.15 delivery cost applied:

$3.493 − $0.15 = $3.343

That is approximately $3.34 before other applicable factors.

The important lesson is this:

The 70% label does not mean you simply receive 70% of every dollar the customer pays.

That is why I don’t tell new authors:

“Amazon pays you 70%.”

That sentence is incomplete.

It is better to understand the actual calculation.

If you want to work through different prices and costs before publishing, I created this KDP royalty calculator for 2026. You can use it to test different prices rather than making your decision from a percentage alone.

Paperback Pricing Works Differently

Paperback pricing requires more care because Amazon deducts the printing cost.

The basic calculation for standard distribution is:

(Royalty rate × list price) − printing cost = royalty

KDP currently offers either a 50% or 60% royalty rate for paperbacks sold through Amazon marketplaces, depending on the list price and marketplace.

For Amazon.com, the current threshold is important:

• $9.98 or below → 50%
• $9.99 or above → 60%

Other marketplaces use their own currency thresholds.

This is one of those details that can completely change the calculation.

Consider a hypothetical 300-page black-and-white paperback on Amazon.com priced at $9.99.

If the applicable printing cost were $4.60, the calculation would be:

($9.99 × 60%) − $4.60

= $5.994 − $4.60

= $1.394

So the estimated royalty would be approximately:

$1.39 per copy

Now imagine that the same book was priced at $14.99.

Using the same $4.60 printing cost for illustration:

($14.99 × 60%) − $4.60

= $4.394

Approximately:

$4.39 per copy

That is a substantial difference.

But there is another side to it.

The $14.99 book also costs the reader more.

That is why I don’t make pricing decisions from the royalty number alone.

Why Paperback Page Count Matters

When I prepare a paperback, I pay attention to page count because printing cost is part of the royalty equation.

Amazon says printing cost depends on factors including:

• marketplace
• page count
• ink type
• trim size
• paper type

KDP calculates the printing cost during the book setup process.

The important lesson for a beginner is this:

Do not decide your paperback price before you know your printing cost.

Upload the actual manuscript specifications.

Let KDP show you the applicable printing cost.

Then work backwards from there.

If you are still preparing your manuscript and need to understand how the print and Kindle versions should be prepared, my Amazon KDP formatting guide for print and Kindle covers that part of the process separately.

I have kept that subject out of this article because formatting and pricing are two different problems.

---

The Price I See Is Not Always the Money I Receive

This is another point new authors sometimes misunderstand.

Suppose you put a paperback on Amazon with a list price of $14.99.

You should not think:

“Amazon sold my book for $14.99, therefore my royalty is $14.99.”

Nor should you assume that a simple percentage of $14.99 is your final amount.

For a standard-distribution paperback, KDP calculates the royalty from the applicable royalty rate and then subtracts printing costs.

The same principle applies to eBooks, although the calculation is different.

That is why I encourage authors to look at the actual estimated royalty shown inside KDP before publishing.

Don’t guess.

---

How I Decide Whether a Price Makes Sense

I normally work through five questions.

1. What format am I selling?

A Kindle eBook and a paperback are not priced the same way simply because they contain the same manuscript.

2. What are comparable books charging?

I look at books that are genuinely comparable in subject, audience, format and length.

Not just any book in the same broad category.

3. What will the reader see as reasonable?

The price has to make sense from the reader’s side.

4. What does KDP say I will actually earn?

I check the estimated royalty.

5. Does the price leave enough room for the book to make economic sense?

A book that earns only a few cents per copy may technically be published, but that does not automatically make it a sensible publishing decision.

This is why I use calculations rather than guessing.

---

Don’t Confuse Royalty With Profit

This distinction is important.

Royalty is not the same thing as profit.

Suppose KDP pays you $4 from a particular book sale.

That does not necessarily mean you made $4 in profit.

You may have spent money on:

• editing
• proofreading
• cover design
• formatting
• advertising
• manuscript preparation
• other publishing expenses

If you spent $500 producing and promoting the book, you have to recover that investment before you can say the project has generated $500 of net profit.

This is why I like to think in two stages:

KDP royalty → publishing economics

First, calculate what Amazon may pay you per sale.

Then consider what it cost you to create and sell the book.

I explain that distinction in more detail in my KDP royalty calculator and earnings guide.

A Practical KDP Pricing Exercise

Before publishing your next book, open a simple note and write down these numbers.

Book format: Paperback

List price: $14.99

Applicable royalty rate: 60%

Printing cost shown by KDP: $4.60

Then calculate:

($14.99 × 0.60) − $4.60 = $4.39

Now ask:

If I sell 10 copies?

10 × $4.39 = $43.90

If I sell 50 copies?

50 × $4.39 = $219.50

If I sell 100 copies?

100 × $4.39 = $439

These are illustrations, not income promises.

Actual KDP earnings can vary according to marketplace, taxes, printing costs, distribution and other factors.

The point of doing the exercise is not to predict sales.

It is to understand the economics before you publish.

---

What I Would Do Before Clicking Publish

After years of publishing books, I have become much more careful about the final KDP screen.

I don’t want to publish first and discover later that I entered the wrong information.

For keywords, I check:

• Does every keyword describe the book?
• Would my reader actually search for this?
• Have I searched the phrase on Amazon?
• Am I unnecessarily repeating words already covered elsewhere in my metadata?
• Have I avoided misleading terms?

For pricing, I check:

• Is this the correct format?
• What are comparable books charging?
• What royalty option applies?
• What is my actual printing cost for the paperback?
• What royalty does KDP estimate?
• Does the price make sense for my intended reader?

For the final royalty calculation, I check the actual figures displayed by KDP rather than relying entirely on an example I found online.

If you want a complete final check before publishing, my First-Time Author Publishing Checklist includes keywords, categories, pricing, uploading, proofing and the other details I recommend checking before publication.

---

A Few KDP Mistakes I Would Avoid

Choosing a keyword because it sounds popular

A keyword is useful only when it is relevant to the book.

Repeating the same keyword seven times

Use the available fields to describe different relevant search ideas rather than filling them with near-identical phrases.

Pricing by copying another author

The other book may have a different page count, format, audience, production cost and pricing strategy.

Looking only at the percentage

“70% royalty” sounds attractive until you understand the applicable deductions and eligibility requirements.

Ignoring paperback printing costs

A paperback price means very little until you know what KDP will deduct for printing.

Assuming a higher price automatically means more money

A higher list price can increase royalty per sale, but it also changes what the reader has to pay.

Treating KDP royalties as profit

Your royalty is only one part of your publishing economics.

---

What I Have Learned From Publishing So Many Books

The biggest lesson for me has been to stop looking for one formula that works for every book.

I have published different kinds of books for different audiences, and I have learned that each book needs to be looked at on its own terms.

The keyword decision is about discoverability.

The pricing decision is about value and market positioning.

The royalty calculation is about understanding the economics of the sale.

They are connected, but they are not the same decision.

When I was new to self-publishing, I was mainly concerned with getting the book published.

Today, I pay much more attention to what happens before I press that final button.

I want to know:

Who is this book for?

What would that reader search for?

What price makes sense for that reader?

What will Amazon actually pay me at that price?

Those questions are much more useful than asking somebody for a magic KDP price.

---

My Simple KDP Formula for Beginners

If you are publishing your first book, keep it simple.

For keywords:

Book subject → reader problem → reader’s search language → Amazon search check → seven relevant keyword fields

For eBook pricing:

Reader value → comparable books → eligible royalty range → estimated royalty → final price

For paperback pricing:

Book specifications → KDP printing cost → applicable royalty rate → reader-facing price → estimated royalty

And always check the current KDP rules because Amazon changes its pricing and royalty requirements.

The 2026 expansion of the 70% eBook royalty price band is a good example. An author relying on older KDP advice could easily make a pricing decision using rules that are no longer current.

---

One More Thing: Don’t Let Your Amazon Listing Undo Your Pricing Work

There is one part of the Amazon page I have deliberately not covered in depth here: the book description.

That deserves its own discussion because pricing gets the reader to consider the purchase, but your listing still has to explain why the book is worth buying.

I have written separately about how to write a better Amazon KDP book description because I don’t want to mix description writing with keyword and royalty calculations and turn this into another generic “complete KDP guide.”

Keeping those subjects separate also makes it easier for you to work through each part of the publishing process.

If You Are Publishing From Nigeria

The KDP pricing and royalty principles apply internationally, but the wider publishing process can look different when you are based in Nigeria.

I know this from personal experience.

When I began self-publishing in 2017, I had to learn how to navigate publishing without simply relying on a traditional publishing house to handle everything for me.

That experience eventually led me to document the Nigerian side separately in my guide to self-publishing a book in Nigeria.

I have deliberately not repeated those Nigerian ISBN, printing and local publishing details here.

They are separate from the question this article is answering.

If your immediate concern is:

“How much will Amazon pay me if I sell this book at this price?”

stay with the KDP royalty calculation.

If your question is:

“How much will it cost me to produce and publish my book in Nigeria?”

that requires a different calculation.
