Understanding Amazon KDP Royalties

Amazon Kindle Direct Publishing (KDP) allows authors to self-publish eBooks and print books (paperbacks and hardcovers) and earn royalties from sales. The royalty structure can seem complex, as it varies significantly between eBooks and print books, and even within eBook options.

eBook Royalties: 35% vs. 70%

For eBooks, KDP offers two primary royalty rate options:

35% Royalty: This rate is generally available for eBooks priced between $0.99 and $200.00 (or equivalent in other currencies). There are no delivery costs deducted from this rate.
70% Royalty: This more attractive rate is available for eBooks priced between $2.99 and $9.99 (or equivalent). However, it comes with a crucial condition: delivery costs are deducted. Delivery costs are calculated based on the eBook's file size (MB) and vary by marketplace. To qualify for 70% royalty, your eBook must also be enrolled in KDP Select (optional, but common) and available in all territories where you have rights.

It's important to note that the 70% royalty option is often more profitable for books within its price range, even with delivery costs, but authors must weigh the pros and cons based on their book's specific file size and pricing strategy.

Paperback Royalties

Paperback royalties on KDP operate on a different model. Authors typically receive a 60% royalty rate on their list price. However, from this 60%, Amazon deducts the print cost of the book. The print cost is a significant factor and depends on several variables:

Page Count: More pages mean higher print costs.
Ink Type: Black & White interiors are significantly cheaper to print than color interiors.
Trim Size: While not an input in this calculator, different book dimensions can slightly affect costs.
Marketplace: Print costs vary by the Amazon marketplace (e.g., US, UK, EU, Canada, Australia, Japan) where the book is sold.

The formula for paperback royalties is: (List Price × 0.60) - Print Cost.

How to Use the Calculator

Select Book Type: Choose whether you want to calculate royalties for an eBook or a Paperback. This will reveal the relevant input fields.
Select Marketplace: Choose the Amazon marketplace where your book will be sold. This affects currency, delivery costs (for eBooks), and print costs (for paperbacks).
Enter Details:
- For eBooks: Enter your desired list price, select your preferred royalty rate (35% or 70%), and if you choose 70%, enter your eBook's file size in MB.
- For Paperbacks: Enter your desired list price, the total page count of your book, and select whether it has a Black & White or Color interior.
Calculate: Click the "Calculate Royalty" button to see your estimated royalty per sale and a breakdown of any associated costs.

Examples:

Example 1: eBook (70% Royalty)

Book Type: eBook
Marketplace: United States (USD)
eBook List Price: $4.99
Royalty Rate: 70%
eBook File Size: 2.5 MB
Calculation: ($4.99 * 0.70) – (2.5 MB * $0.15/MB) = $3.49 – $0.375 = $3.115
Estimated Royalty: $3.12

Example 2: Paperback (Black & White)

Book Type: Paperback
Marketplace: United States (USD)
Paperback List Price: $12.99
Page Count: 250
Ink Type: Black & White Interior
Calculation: Print Cost (US B&W, 250 pages): $0.75 + (250 * $0.012) = $0.75 + $3.00 = $3.75. Royalty: ($12.99 * 0.60) – $3.75 = $7.794 – $3.75 = $4.044
Estimated Royalty: $4.04

This calculator provides estimates based on typical KDP rates. Actual royalties may vary slightly due to rounding, specific regional pricing, or changes in KDP's terms.
