Question 1

What is KDP and how do royalties work?

Accepted Answer

KDP (Kindle Direct Publishing) is Amazon's self-publishing platform for ebooks and paperbacks. For ebooks, authors choose between 35% or 70% royalty options. The 35% royalty applies to all prices ($0.99-$200), while 70% royalty is available only for $2.99-$9.99 pricing. The 70% option deducts delivery costs based on file size ($0.15/MB in US). Paperbacks earn 60% of list price minus printing costs.

Question 2

How do you calculate KDP royalties?

Accepted Answer

For ebook 35% royalty: Royalty = List Price × 0.35. For ebook 70% royalty: Royalty = (List Price × 0.70) - (File Size in MB × $0.15). For paperback: Royalty = (List Price × 0.60) - Print Cost. For example, a $4.99 ebook with 2MB file size: 70% royalty = ($4.99 × 0.70) - (2 × $0.15) = $3.493 - $0.30 = $3.19 per sale.

Question 3

Should I choose 35% or 70% royalty for my Kindle book?

Accepted Answer

Choose 70% royalty if: your price is $2.99-$9.99, your file size is under 10MB, and you're selling in KDP Select enrolled territories. Choose 35% royalty if: your price is under $2.99 or over $9.99, you have large file sizes with many images, or you're selling in non-Select territories. For most authors, $2.99-$4.99 with 70% royalty maximizes earnings while remaining competitive.

Question 4

What is the sweet spot for KDP pricing?

Accepted Answer

The sweet spot for KDP ebook pricing is $2.99-$4.99. This range qualifies for the 70% royalty while remaining affordable for readers. $2.99 is popular for first books in a series, $3.99 for full-length novels, and $4.99 for non-fiction or longer works. At $2.99 with 70% royalty, you earn about $2.04 per sale. At $4.99, you earn about $3.43 per sale (after delivery costs).

Question 5

How does file size affect KDP royalties?

Accepted Answer

File size directly impacts 70% royalty earnings through delivery costs. Amazon charges approximately $0.15 per megabyte for delivery in the US (varies by marketplace). A 10MB ebook has $1.50 in delivery costs, significantly reducing your net royalty. Optimize file size by compressing images, using efficient formats, and removing unnecessary elements. Keep ebooks under 5MB when possible for better royalties.

Question 6

What are KDP print costs for paperbacks?

Accepted Answer

KDP paperback print costs vary by: page count, trim size (6×9 most common), paper type (white or cream), and marketplace. Formula: $0.85 base + ($0.012 × page count) for black & white. For example, a 200-page 6×9" book costs approximately $3.25 to print. With a $12.99 list price, your royalty would be ($12.99 × 0.60) - $3.25 = $7.79 - $3.25 = $4.54 per sale.

Question 7

Can you earn more with 35% royalty than 70%?

Accepted Answer

Yes, in specific cases 35% can earn more than 70%. If you price above $9.99, you can only use 35% royalty. A $14.99 book earns $5.25 (35%) versus a $9.99 book earning about $6.64 (70% after delivery). However, higher prices typically reduce sales volume. The 35% option also allows worldwide distribution without Select enrollment restrictions. Test both pricing strategies to find optimal balance of price, volume, and total revenue.

Question 8

What is KDP Select and how does it affect royalties?

Accepted Answer

KDP Select is an optional program offering additional benefits: 70% royalty in select countries (India, Brazil, Japan, Mexico), Kindle Countdown Deals and Free Book Promotions, Kindle Unlimited (KU) page read royalties, and higher visibility in Amazon algorithms. However, it requires 90-day exclusivity (no selling on other platforms). KU pays about $0.004-$0.005 per page read from a global fund, which can supplement royalties significantly for popular books.

Question 9

How do KDP royalties vary by marketplace?

Accepted Answer

Royalty rates are consistent (35% or 70%), but delivery costs and currency vary. US: $0.15/MB delivery. UK: ~£0.10/MB delivery. EU: ~€0.12/MB delivery. Prices must be set for each marketplace, and Amazon auto-converts or you can set custom prices. Consider exchange rates and local competition when pricing internationally. Some markets have different price thresholds for 70% royalty eligibility.

Question 10

What strategies maximize KDP author earnings?

Accepted Answer

Maximize KDP earnings by: pricing ebooks at $2.99-$4.99 for 70% royalty, optimizing file size to reduce delivery costs, creating series to increase reader lifetime value, using KDP Select for KU page read income, pricing paperbacks competitively (research category), running promotions during launch, building email list for direct reader engagement, and publishing regularly to build catalog. Many successful authors earn more from 10 books at $2.99 than 1 book at $9.99.
