KDP Royalties Explained: How Much Will You Actually Earn Per Sale?

Amazon KDP pays authors either 35 percent or 70 percent of the list price on ebook sales, minus a delivery fee on the 70 percent option. That single sentence contains more complexity than most new authors realize. The difference between a well-optimized price point and a naive one can mean thousands of dollars per year in lost royalties, even at modest sales volumes.

This guide breaks down the exact mechanics of KDP royalties for both ebooks and paperbacks, with real calculation examples so you can make pricing decisions based on numbers rather than guesswork. For instant calculations on your specific book, use the KDP Royalty Calculator.

Ebook Royalties: The 35% vs 70% Decision

When you publish an ebook on KDP, you choose one of two royalty rates. This is not a negotiation. Amazon sets the terms, and you pick the option that suits your book.

The 35% Royalty Option

Your royalty = List Price x 35%

No delivery fee. No file size considerations. Simple math.

Available for books priced at $0.99 to $200.00.

Example: A book priced at $2.99 earns $1.05 per sale.

Example: A book priced at $0.99 earns $0.35 per sale.

The 70% Royalty Option

Your royalty = (List Price - Delivery Cost) x 70%

Available for books priced at $2.99 to $9.99. This is the range Amazon incentivizes because it aligns with consumer price expectations for ebooks.

The delivery cost is based on file size: approximately $0.15 per megabyte in 2026. For a typical nonfiction ebook without heavy graphics, the file size runs 1 to 3 MB, resulting in a delivery cost of $0.15 to $0.45. Image-heavy books can run 5 to 10 MB, with delivery costs of $0.75 to $1.50.

Example: A text-heavy nonfiction book priced at $9.99 with a 2 MB file size:

• Delivery cost: $0.30
• Royalty: ($9.99 - $0.30) x 0.70 = $6.78 per sale

Example: The same book priced at $4.99:

• Delivery cost: $0.30
• Royalty: ($4.99 - $0.30) x 0.70 = $3.28 per sale

Example: A book priced at $2.99 with a 1.5 MB file size:

• Delivery cost: $0.23
• Royalty: ($2.99 - $0.23) x 0.70 = $1.93 per sale

When Does 35% Beat 70%?

Almost never within the $2.99 to $9.99 range. At $2.99, the 70% option yields $1.93 (assuming typical delivery cost) versus $1.05 at 35%. The 70% option wins by a wide margin at every price point within the qualifying range.

The 35% option exists for two scenarios:

• Books priced below $2.99 (typically $0.99 promotional pricing)
• Books priced above $9.99 (textbooks, specialized reference works)

At $0.99, you are locked into 35%, earning $0.35 per sale. This is viable only as a temporary promotional price to drive reviews and rankings, not as a long-term strategy.

At prices above $9.99, you are also locked into 35%. A book priced at $14.99 earns $5.25 per sale at 35%, compared to $6.78 at $9.99 with 70%. This means you earn less per sale at $14.99 than at $9.99, which is why very few self-published ebooks are priced above $9.99.

The $2.99 to $9.99 Sweet Spot

Amazon designed the 70% royalty tier to keep ebook prices between $2.99 and $9.99. This is not subtle. The incentive structure makes it economically irrational to price outside this range for most authors.

Royalty at Each Price Point (assuming 2 MB file, $0.30 delivery cost)

The table makes the pricing strategy obvious: price at $9.99 for maximum royalty per sale, or price lower only if you believe the increased volume will compensate for the reduced per-sale earnings.

Pricing Strategy by Genre and Goal

Business and professional nonfiction: $7.99 to $9.99. Readers in this category are accustomed to paying for expertise. A book priced at $4.99 may actually signal lower quality to this audience.

Self-help and personal development: $4.99 to $7.99. More price-sensitive audience, larger potential volume.

Short nonfiction (under 30,000 words): $2.99 to $4.99. Readers expect lower prices for shorter books.

Lead generation books (book as business card): $0.99 to $2.99. The goal is distribution, not royalties. You make money on the back end through consulting, courses, or services.

Paperback Royalties

Paperback economics are entirely different from ebooks. Amazon prints each copy on demand, and the printing cost is deducted from your royalty.

The Paperback Royalty Formula

Your royalty = (List Price x 60%) - Printing Cost

You always receive 60% of the list price, minus the cost Amazon charges to print the book. There is no 35%/70% choice for paperbacks.

Printing Cost Formula (2026 rates, US marketplace)

Printing cost = Fixed cost + (Per-page cost x Page count)

For black-and-white interior on white paper:

• Fixed cost: $0.85
• Per-page cost: $0.012

For black-and-white interior on cream paper:

• Fixed cost: $0.85
• Per-page cost: $0.012

For color interior:

• Fixed cost: $0.85
• Per-page cost: $0.065

Paperback Calculation Examples

A 200-page black-and-white nonfiction book priced at $16.99:

• Printing cost: $0.85 + ($0.012 x 200) = $3.25
• Royalty: ($16.99 x 0.60) - $3.25 = $10.19 - $3.25 = $6.94 per sale

A 300-page book priced at $18.99:

• Printing cost: $0.85 + ($0.012 x 300) = $4.45
• Royalty: ($18.99 x 0.60) - $4.45 = $11.39 - $4.45 = $6.94 per sale

A 150-page book priced at $14.99:

• Printing cost: $0.85 + ($0.012 x 150) = $2.65
• Royalty: ($14.99 x 0.60) - $2.65 = $8.99 - $2.65 = $6.34 per sale

A 200-page color interior book priced at $29.99:

• Printing cost: $0.85 + ($0.065 x 200) = $13.85
• Royalty: ($29.99 x 0.60) - $13.85 = $17.99 - $13.85 = $4.14 per sale

Color printing is expensive. Unless your book requires color (photography, cookbooks, children's books), black-and-white interior saves you $10 or more per copy in printing costs.

Paperback Pricing Strategy

The minimum list price must cover your printing cost. Amazon will not let you set a price that results in a negative royalty. Beyond that minimum, paperback pricing follows genre conventions:

• Business nonfiction: $15.99 to $19.99
• Self-help: $14.99 to $17.99
• Memoir: $15.99 to $18.99
• Academic/reference: $24.99 to $39.99
• Short books (under 150 pages): $12.99 to $14.99

International Marketplace Differences

KDP operates in 13 marketplaces: US, UK, Germany, France, Spain, Italy, Netherlands, Japan, Brazil, Canada, Mexico, Australia, and India. Royalty rates and delivery costs vary by marketplace.

Key differences:

70% royalty availability: The 70% option is available in all 13 marketplaces, but the qualifying price range varies by currency. In the UK, the range is 1.49 to 6.99 GBP. In India, it is 99 to 449 INR.

Delivery costs vary. The per-MB rate is lower in some markets and higher in others. The US rate of approximately $0.15/MB is on the higher end.

Expanded distribution: If you enable "expanded distribution" for paperbacks (making your book available through third-party sellers and libraries), your royalty drops to 40% of list price instead of 60%.

Currency considerations: You set prices in each marketplace's currency. Amazon provides suggested prices based on exchange rates, but you can override them. Some authors price slightly below the converted rate in price-sensitive markets like India and Brazil.

For most self-published nonfiction authors, the US marketplace generates 60 to 70 percent of sales. The UK and Canada together account for another 15 to 20 percent. The remaining marketplaces contribute 10 to 25 percent collectively.

Monthly Income Projections

Here is what different sales volumes translate to in monthly income, assuming a $9.99 ebook at 70% royalty ($6.78 per sale) and a $16.99 paperback ($6.94 per sale, 200-page book):

For context on what these sales volumes mean:

• 1 sale per day puts you in the top 15 to 20 percent of all KDP books. Most self-published books sell fewer than one copy per day.
• 5 sales per day puts you in the top 5 percent. This is a solidly performing nonfiction title.
• 25 sales per day is a bestseller in most nonfiction categories. Very few self-published books sustain this volume.
• 50 sales per day is exceptional. This is top-1-percent territory, typically achieved only with significant marketing spend or viral organic reach.

Real-World Author Earnings Data

Data from published author income surveys and marketplace analysis in 2025-2026 shows:

• The median self-published author earns under $1,000 per year from book sales.
• The top 10 percent of self-published authors earn $10,000 to $50,000 per year.
• The top 1 percent earn over $100,000 per year.
• Authors who publish 3 or more books earn significantly more on average than single-book authors, because each book cross-promotes the others.

These numbers reflect direct book royalties only. Many nonfiction authors earn substantially more from indirect benefits: consulting clients, speaking engagements, course sales, and professional opportunities that come from being a published author.

How to Optimize Your Price Point

The Elasticity Test

If you have an established title, test different price points over 30-day periods and measure total revenue (not just per-sale royalty). A lower price with higher volume can outperform a higher price with lower volume.

Example:

• At $9.99 (royalty $6.78): 100 sales/month = $678/month
• At $5.99 (royalty $3.98): 200 sales/month = $796/month

In this case, the lower price generates more total revenue despite the lower per-sale royalty.

Price Anchoring with Paperback

Set your paperback price 50 to 70 percent higher than your ebook price. This makes the ebook look like a deal by comparison. A $16.99 paperback next to a $6.99 ebook makes the ebook feel like a bargain.

The KDP Countdown Deal

KDP allows periodic Countdown Deals where you temporarily reduce your price while keeping the 70% royalty rate. This is one of the few situations where pricing below $2.99 still earns 70% royalties. Use it strategically for launches and promotions.

Kindle Unlimited Considerations

If you enroll in KDP Select (which makes your ebook exclusive to Amazon), your book is available through Kindle Unlimited. KU pays per page read rather than per sale. The per-page rate fluctuates but has averaged approximately $0.004 to $0.005 per page in recent months. A 250-page book read in full earns roughly $1.00 to $1.25.

KU can be worth it for fiction and short nonfiction that gets high read-through rates. For longer nonfiction where readers may not read cover to cover, per-sale royalties usually outperform KU page reads.

Common Pricing Mistakes

Pricing Too Low

Setting your ebook at $0.99 or $1.99 signals "this is not a serious book." For nonfiction, low pricing actually reduces sales because buyers associate price with quality. A $2.99 business book looks like it contains $2.99 worth of insight.

Pricing Too High

Ebooks priced above $9.99 earn 35% instead of 70%, and the higher price reduces volume. You need to sell nearly twice as many copies at $9.99 as at $12.99 to earn the same revenue, and the lower price point typically generates more than double the volume.

Not Accounting for Delivery Costs

Authors with image-heavy books sometimes price at $2.99 thinking they will earn around $2.10 at 70%, only to discover their 8 MB file generates $1.20 in delivery costs, reducing the royalty to $1.25. Always calculate your actual delivery cost before setting your price.

Ignoring the Paperback-Ebook Relationship

Your ebook and paperback prices should work together. If your paperback is $14.99 and your ebook is $12.99, there is no incentive to buy the ebook. Price the ebook at 40 to 60 percent of the paperback price.

Running Your Own Numbers

The variables that determine your royalty are: list price, file size (for ebooks), page count (for paperbacks), and marketplace. Plug your specific numbers into the KDP Royalty Calculator to see your exact per-sale royalty across all formats and marketplaces.

For authors still in the writing phase, knowing these numbers early shapes decisions about book length and content type. A 50,000-word text-only nonfiction book is the most royalty-efficient format: low delivery cost on ebook, reasonable printing cost on paperback, and pricing flexibility across the full $2.99 to $9.99 range.

Every dollar of royalty optimization compounds over the life of a book. A pricing change that adds $1.00 per sale generates $365 more per year at just one sale per day. Over a book's typical 5-to-10-year earning life, that is $1,800 to $3,650 from a decision that takes five minutes to make with the right data.
