If you are planning to self-publish on Amazon Kindle Direct Publishing (KDP), understanding royalties is one of the most important things you need to get right. Many new authors focus only on writing and publishing, but later feel confused or disappointed when they see their earnings for the first time.
Amazon KDP royalties are not complicated, but they are often misunderstood. How much you earn depends on several factors, such as book format, pricing, country of sale, and whether your book is enrolled in KDP Select. In this guide, we will break everything down in a clear, practical, and beginner-friendly way, so you know exactly how Amazon pays authors and how you can maximize your earnings.
What Are Amazon KDP Royalties?
Amazon KDP royalties are the share of the book price that Amazon pays to you, the author, for each sale or read. Every time someone buys your eBook or paperback, Amazon takes its commission and pays you the remaining amount as royalty.
Your final earnings are influenced by:
- The format of your book (eBook or paperback)
- The price you set
- The marketplace where the sale happens
- Delivery or printing costs
- Enrollment in KDP Select (for eBooks)
Because of these variables, two books with the same price can earn very different royalties.
Understanding the Two Amazon KDP eBook Royalty Options
Amazon offers two royalty options for eBooks: 35% and 70%. At first glance, the difference looks simple, but the rules behind each option matter a lot.
35% vs 70% Royalty: A Simple Comparison
| Feature | 35% Royalty Option | 70% Royalty Option |
|---|---|---|
| Available for | All eBooks | Eligible eBooks only |
| Price requirement | Any price | $2.99 – $9.99 |
| Delivery fee | No | Yes (file-size based) |
| Earnings per sale | Lower | Higher |
| Best suited for | Very low-priced books | Serious long-term authors |
Most professional self-published authors aim for the 70% royalty, but it is important to understand when each option applies.
Amazon KDP 35% Royalty Explained
The 35% royalty option is available for all eBooks, regardless of price or region. The calculation is straightforward: Amazon pays you 35% of your book’s list price for every sale.
For example, if your eBook is priced at $1.00, you earn $0.35 per sale. There are no delivery costs deducted, which makes this option easy to understand.
However, the downside is clear. Even with good sales volume, earnings remain low. This option is usually chosen only when authors intentionally price their books below $2.99, such as for short guides or promotional content.
Amazon KDP 70% Royalty Explained (Most Popular Option)
The 70% royalty option is far more attractive, but it comes with specific requirements. Amazon uses these rules to maintain pricing balance across its platform.
To qualify for a 70% royalty:
- Your eBook price must be between $2.99 and $9.99
- The eBook price must be at least 20% lower than the lowest-priced paperback or hardcover edition
- The book must be available in all regions where you own distribution rights
In addition, for sales in India, Brazil, Japan, and Mexico, your eBook must be enrolled in KDP Select to earn the 70% royalty.
Once these conditions are met, Amazon pays 70% of the list price after deducting delivery costs.
What Is Amazon KDP Delivery Cost?
Delivery cost is a fee Amazon charges for delivering your eBook file to readers. This cost is calculated based on the file size of your eBook, and it varies by country.
In the United States, Amazon charges $0.15 per megabyte.
For example, if your eBook file size is 3 MB, Amazon deducts $0.45 from your royalty on each sale. This deduction happens after the 70% royalty is calculated, which surprises many first-time authors.
This is why large image-heavy books can earn less than expected, even with good pricing.
How Authors Can Reduce Delivery Costs
Reducing delivery costs is one of the easiest ways to increase net earnings. Authors can do this by compressing images, avoiding unnecessary graphics, and using clean formatting. For text-based books, delivery fees are usually very small and almost negligible.
KDP Select and Kindle Unlimited: An Extra Income Stream
When you enroll your eBook in KDP Select, you agree to sell the digital version exclusively on Amazon for 90 days. In return, your book becomes available on Kindle Unlimited, Amazon’s subscription service.
Kindle Unlimited readers do not buy your book. Instead, they read it as part of their subscription, and you earn money based on pages read.
These payments come from the KDP Select Global Fund, which Amazon distributes among authors every month.
For authors writing fiction, romance, thrillers, or series-based content, Kindle Unlimited can be a major source of income and visibility.
Amazon KDP Paperback Royalties Explained
Paperback royalties work differently from eBooks. Instead of choosing between two royalty rates, Amazon uses a fixed formula.
For paperbacks, you earn:
60% of the list price minus printing cost
Printing cost depends on:
- Number of pages
- Ink type (black & white or color)
A 200-page black-and-white paperback will cost less to print than a color paperback of the same length, which directly affects your earnings.
Example: How Much Do Authors Actually Earn?
| Book Type | Price | Royalty Model | Costs Deducted | Approx. Earnings |
|---|---|---|---|---|
| eBook | $4.99 | 70% | $0.45 delivery | ~$3.04 |
| eBook | $1.99 | 35% | None | ~$0.70 |
| Paperback | $12.99 | 60% | Printing cost | Varies |
These examples show why pricing and format decisions matter so much.
How to Track Your Amazon KDP Royalties
Amazon provides a Royalties Dashboard inside your KDP account, where you can track:
- Daily sales
- Royalties earned
- Kindle Unlimited page reads
- Marketplace-wise performance
Payments are made monthly, approximately 60 days after the end of the month in which the sale occurred.
How Authors Can Maximize Amazon KDP Earnings
Maximizing royalties is not about shortcuts. It comes from making smart, informed decisions. Pricing your eBook between $2.99 and $9.99 allows you to qualify for the higher royalty rate. Optimizing file size keeps delivery costs low. Regularly checking your KDP reports helps you understand which books and formats are performing best.
For authors enrolled in KDP Select, tools like Kindle Countdown Deals allow temporary discounts below $2.99 while still earning 70% royalty. This is one of the most effective ways to increase visibility without sacrificing long-term income.
