KDP Royalty Calculator 2026: Calculate Your Amazon Book Earnings

Publishing a book on Amazon can be exciting—but before you set your price, one question matters:

How much will you actually earn from each book you sell?

A book that sells for $14.99 does not necessarily put $14.99 in your pocket. Your KDP royalty can be affected by the royalty rate, delivery costs for eBooks, printing costs for paperbacks, your distribution option, and other factors.

That’s why we created this free KDP Royalty Calculator.

Use it to estimate your potential earnings from Kindle eBooks and paperback books, calculate your projected monthly and annual royalties, and estimate how many copies you may need to sell to recover your publishing and marketing investment.

Calculating your royalty is a waste of time when you don’t even know what to do to publish your book from start to finish. If you are an author in Nigeria you may need to check this: How to Self-Publish a Book in Nigeria: Step-by-Step Guide for First-Time Authors↗

What Is a KDP Royalty?

A KDP royalty is the amount an author receives from Amazon when a customer purchases their book through Kindle Direct Publishing.

Your royalty isn't simply the book's list price.

For example, a paperback selling for $14.99 may have a printing cost deducted before the author's royalty is calculated.

Similarly, an eligible Kindle eBook sold under Amazon's 70% royalty option may have a delivery cost deducted from the royalty calculation.

This means your book price and your actual royalty are two different numbers.

Understanding the difference is important when deciding how to price your book.

---

How Much Does Amazon KDP Pay Authors?

There isn't one single KDP royalty rate that applies to every book.

The applicable royalty depends on factors such as:

• Whether the book is an eBook or print book
• The list price
• The marketplace where the book is sold
• The distribution option
• Whether the book qualifies for a particular royalty option
• Printing costs for print books
• Delivery costs for eligible eBooks

For this reason, authors should calculate their expected royalty instead of assuming that they will receive a fixed percentage of their book price.

KDP eBook Royalty Calculator

For Kindle eBooks, KDP has different royalty options depending on the applicable requirements.

Under the 70% royalty option, the royalty calculation generally takes the form of:

(List Price × 70%) − Applicable Delivery Costs = Estimated Royalty

For example, if an eligible eBook is priced at $4.99 and the applicable delivery cost is $0.15:

($4.99 × 70%) − $0.15 = $3.343

That would be approximately $3.34 per sale before any applicable taxes or other deductions.

Your actual calculation can differ depending on the marketplace, book file and other KDP requirements.

What about the 35% royalty option?

Some eBooks may fall under the 35% royalty option.

The basic calculation is:

List Price × 35% = Estimated Royalty

For example:

$4.99 × 35% = $1.7465

That's approximately $1.75 per sale.

The important lesson is that an author shouldn't choose a book price simply because it looks attractive to readers.

You should also consider how that price affects your actual royalty.

---

KDP Paperback Royalty Calculator

Paperback royalties work differently from Kindle eBook royalties.

For a paperback sold through standard distribution, the basic calculation is:

(List Price × Applicable Royalty Rate) − Printing Cost = Estimated Royalty

For example, suppose your paperback has:

• List price: $14.99
• Royalty rate: 60%
• Printing cost: $4.60

The calculation would be:

($14.99 × 60%) − $4.60 = $4.394

That's approximately $4.39 per copy.

This is why knowing your book's printing cost is extremely important.

Two books with exactly the same selling price can have very different royalties if their printing costs are different.

---

Why Your KDP Printing Cost Matters

If you're publishing a paperback, don't look only at the selling price.

You also need to consider:

• Trim size
• Page count
• Ink type
• Marketplace
• Binding specifications
• Distribution option

These factors can affect the printing cost.

For that reason, when using our calculator, enter the actual printing cost displayed by KDP for your particular book whenever possible.

That will give you a much more useful estimate than simply guessing the printing cost.

How to Calculate Your KDP Profit

There is an important distinction between royalty and profit.

Your KDP royalty is what Amazon pays you from a book sale according to the applicable royalty calculation.

Your actual profit may be lower after considering the money you spent creating and marketing the book.

For example, suppose you spend:

• $300 on editing
• $100 on cover design
• $50 on formatting
• $200 on advertising

Your total investment is:

$650

If your estimated royalty is $4 per sale, you would need approximately:

$650 ÷ $4 = 162.5

So you would need about 163 sales to recover that initial investment.

This is your approximate break-even point.

That is why our calculator also includes a break-even calculation.

How Many Books Do You Need to Sell to Make $1,000?

This depends on your royalty per sale.

For example:

Royalty per Sale	Sales Needed for $1,000
$1	1,000
$2	500
$3	334
$4	250
$5	200
$10	100

The calculation is simple:

Target Income ÷ Royalty Per Sale = Sales Required

So if your royalty is $4 per book:

$1,000 ÷ $4 = 250 sales

This doesn't mean you should automatically increase your price to maximize royalty.

A higher price may increase your royalty per sale, but it can also affect how attractive the book is to your target readers.

The objective is to find a price that makes sense for both your readers and your publishing business.

---

How Many Books Do You Need to Sell to Make $1,000 Per Month?

You can use the same formula.

If you earn $5 per sale:

$1,000 ÷ $5 = 200 sales per month

That means approximately:

200 sales per month ÷ 30 days = 6.7 sales per day

So you'd need roughly seven sales per day to generate approximately $1,000 in monthly royalties at a $5 royalty per sale.

This is why understanding your royalty per sale is useful.

Instead of simply saying:

"I want to make $1,000 from my book."

You can work backward and determine how many sales you actually need.

---

KDP Royalty vs Book Price

One of the biggest mistakes new authors make is assuming:

"If my book costs $10, I'll make $6 or $7 from every sale."

That's not necessarily true.

Your royalty depends on the applicable Amazon royalty structure and costs associated with the book.

For a paperback, printing costs are particularly important.

For an eBook, the applicable royalty option and delivery cost can affect the amount you receive.

Therefore, don't choose your price based solely on what other authors are charging.

Consider:

1. Your target reader
2. Your book's category
3. Your book's length
4. Comparable books
5. Your production costs
6. Your marketing costs
7. Your desired royalty
8. The applicable KDP pricing requirements

KDP Royalty Calculator Example

Let's look at a simple example.

Imagine you're publishing a paperback.

Your book sells for:

$14.99

Your applicable royalty rate is:

60%

Your KDP printing cost is:

$4.60

Your estimated royalty is:

($14.99 × 60%) − $4.60

= $4.39 per sale

If you sell 25 copies in a month:

25 × $4.39 = $109.75

If you sell 100 copies:

100 × $4.39 = $439

If you sell 500 copies:

500 × $4.39 = $2,195

These figures are estimates and should not be interpreted as guaranteed income.

The calculator allows you to change the numbers and see how different prices and sales volumes affect the result.

Don't Confuse KDP Royalties With Your Total Publishing Costs

Your KDP royalty calculator answers one question:

"How much might I earn from each sale?"

Your publishing cost calculator answers another:

"How much might it cost me to create and market my book?"

You need both numbers to understand your publishing business.

For example:

Publishing investment: $800

Royalty per sale: $4

Break-even point: 200 sales

This gives you a much clearer picture than simply knowing that Amazon pays a particular royalty percentage.

How to Increase Your KDP Earnings

Increasing your KDP income isn't simply about raising your book price.

You need to think about the entire publishing system.

1. Improve Your Book

A professional manuscript, useful content, strong cover and good formatting can improve the reader's experience.

2. Choose Your Price Carefully

Your price should make sense for your category, audience and book format.

3. Understand Your Royalty

Know how much you actually receive from each sale.

4. Track Your Sales

Don't guess.

Monitor your actual sales and royalties in your KDP account.

5. Build Your Author Platform

Your own website, email list, social media presence and other marketing channels can help you reach readers outside Amazon.

6. Promote Your Book

A good book still needs visibility.

Consider appropriate promotional strategies for your target audience and category.

Is KDP Worth It for Self-Published Authors?

KDP can be an attractive publishing option because it allows authors to make books available through Amazon without managing a traditional print inventory for standard print-on-demand publishing.

But KDP isn't a guarantee of sales.

Publishing a book and selling a book are two different things.

Your book still needs:

• A clear target audience
• A compelling title
• A professional cover
• Quality content
• Appropriate pricing
• Strong book description
• Discoverability
• Marketing

Think of KDP as the publishing and distribution platform, not the entire marketing strategy.

Frequently Asked Questions

How does the KDP royalty calculator work?

The calculator uses the information you provide—such as list price, royalty rate, delivery cost or printing cost—to estimate your royalty per sale and potential earnings.

Does Amazon KDP pay 70% royalties?

Eligible Kindle eBooks can qualify for a 70% royalty option under Amazon's applicable requirements. Not every eBook sale necessarily qualifies for 70%.

How much does KDP pay for paperback books?

Paperback royalties depend on the applicable royalty rate and printing cost. A simplified calculation is:

(List Price × Royalty Rate) − Printing Cost

Does KDP charge authors to publish?

KDP generally allows authors to publish books without an upfront publishing fee. However, authors may still incur costs for services such as editing, cover design, formatting, marketing or other publishing expenses.

Can I calculate my KDP earnings before publishing?

Yes. You can estimate your potential earnings by entering your planned price, applicable royalty rate and relevant costs into a KDP royalty calculator.

How many books do I need to sell to make $1,000?

Divide $1,000 by your estimated royalty per sale.

For example, if your royalty is $5:
