How KDP Royalties Are Calculated
KDP royalties depend on your book format, list price, marketplace, and production costs. For Kindle eBooks, authors typically choose between the 35% and 70% royalty options. For print books, royalties are calculated by applying the royalty rate to the list price and then subtracting printing costs.
For paperbacks and hardcovers, the basic formula is:
Royalty = (Royalty Rate x List Price) - Printing Cost
That means a book priced at $14.99 with a 60% royalty rate and a $4.60 printing cost would earn:
($14.99 x 0.60) - $4.60 = $4.39 royalty per sale
Why Printing Cost Matters
Printing cost is one of the biggest factors affecting paperback and hardcover profit. Page count, trim size, ink type, marketplace, and color interiors can all change your bottom line.
Puzzle books, journals, workbooks, planners, and activity books often have higher page counts, so authors should test several price points before publishing.
Questions Authors Ask About KDP Royalties
What is the difference between 70% and 35% Kindle royalties?
The 70% option can produce higher royalties, but your book must meet Amazon’s eligibility rules, including pricing and marketplace requirements. The 35% option applies more broadly but pays a lower percentage.
How do I calculate paperback royalties?
Paperback royalties are usually calculated by multiplying your list price by the royalty rate, then subtracting the printing cost.
Should I use Expanded Distribution?
Expanded Distribution may help your book reach more sales channels, but the royalty rate is usually lower. Authors should compare standard Amazon royalties against expanded distribution before deciding.
How do I find my minimum list price?
Your minimum list price is based on printing cost and royalty rate. If your price is too low, your royalty can shrink or disappear.
Can I change my KDP price later?
Yes. Authors can update pricing in KDP after publishing, but changes may take time to appear across Amazon marketplaces.
KDP Pricing Strategy for Authors
A smart book price should do more than cover printing costs. It should also support your marketing goals, reader expectations, and long-term author brand.
Before choosing your price, test several scenarios:
- Low price for volume
- Mid-range price for balanced profit
- Premium price for specialized books
- Expanded distribution pricing
- Paperback vs. hardcover profit
