KDP Royalties Explained: What You Actually Earn (With Worked Math)

Amazon KDP pays ebook royalties at two rates: 35% or 70%, depending on your list price. The 70% tier is available for ebooks priced between $2.99 and $12.99, a ceiling Amazon raised from $9.99 to $12.99 on July 7, 2026, the first change since KDP launched in 2007. Below $2.99 or above $12.99, you earn 35%.

Every KDP royalty structure is covered below: ebook tiers and delivery fees, paperback and hardcover formulas (including the June 2025 pricing cliff), Kindle Unlimited page-read earnings, expanded distribution, and tax treatment for non-US authors. Every section includes worked dollar math so you know exactly what lands in your account.

Key Takeaways

• The 70% ebook royalty applies to prices between $2.99 and $12.99 (USD); the upper ceiling rose from $9.99 on July 7, 2026.
• Amazon deducts a delivery fee (US: $0.15/MB) before calculating 70%: your net is not simply 70% of list price.
• Paperback royalties are 60% at $9.99+ and 50% at $9.98 and below (a change Amazon made in June 2025).
• Kindle Unlimited pays per normalized page read; at ~$0.0045/KENP, a full read of a 300-page book earns about $1.35 versus $4.09 for a direct 70%-tier sale at $5.99.
• Non-US authors face a 30% US withholding tax by default, reducible to 0% in many countries via Form W-8BEN.

What Are KDP Royalties?

KDP (Kindle Direct Publishing) royalties are the per-unit payments Amazon makes to self-published authors for ebook, paperback, and hardcover sales through its publishing platform. Unlike traditional publishing (where an author typically earns 7.5–15% of retail price through a publisher), KDP pays you directly as the publisher.

83% of indie authors cite Amazon as their primary revenue platform. 2.6 million self-published titles carry ISBN assignments in the US as of 2023, and the KDP Trends index shows self-publishing searches up 19% year-over-year. Understanding exactly how KDP calculates what you earn is the single most important thing a new self-publisher can do before setting a price.

Why the 70% Tier Is Not What It Appears

The most common misconception about KDP royalties: "70% means I keep 70% of my list price." That's close, but not accurate. Amazon subtracts a per-MB delivery fee before the 70% rate applies.

For most text ebooks, the fee is small. For illustrated or large-file books, it can flip which tier pays better.

Understanding the actual formula prevents pricing mistakes that cost you royalties on every copy you sell.

How KDP Ebook Royalties Work

The Two Royalty Tiers

KDP's ebook royalty structure has two options; you choose which applies when you publish:

The 70% rate requires your ebook to be priced between $2.99 and $12.99. Below $2.99 or above $12.99, Amazon applies 35% automatically: you cannot choose 70% outside the window.

Before July 7, 2026, the upper ceiling was $9.99. Amazon held that ceiling for 19 years. The Authors Guild welcomed the change, noting the $9.99 ceiling had long compressed pricing for longer works, box sets, and specialized nonfiction.

The Delivery Fee: How It Affects 70%-Tier Earnings

The 70% tier delivery fee is $0.15 per megabyte (US). Other markets: UK £0.10/MB, EU €0.12/MB.

The formula: Royalty = 70% × (list price − delivery cost)

Worked examples at common price points (text ebook, 1 MB):

The delivery fee is negligible on text books. A 1 MB file costs $0.15, reducing a $9.99 ebook royalty from $6.99 to $6.89. The rate advantage of 70% far outweighs it.

The Edge Case Where 35% Beats 70%

For large-file ebooks (children's books, heavily illustrated guides, recipe books with many full-resolution images), the per-MB delivery fee can eliminate the 70%-tier advantage entirely. This edge case is absent from most royalty explainers.

Example: a $4.99 illustrated ebook at 20 MB.

• 70% plan: 0.70 × ($4.99 − $3.00) = $1.39
• 35% plan: 0.35 × $4.99 = $1.75

The 35% plan pays more. At 20 MB, the $3.00 delivery fee erodes the royalty faster than the higher rate compensates. The crossover point shifts with list price, but for any ebook above roughly 6–8 MB at a price under $6, you should calculate both options before publishing.

The fix: compress images to 72–150 DPI (screen resolution) before Kindle conversion. Reducing an illustrated book from 20 MB to 4 MB recovers most of the 70%-tier advantage.

Eligibility Gates for the 70% Tier

Beyond the price window, the 70% option has additional requirements per Amazon's help page:

• The ebook cannot consist primarily of public domain content.
• The ebook price must be within 20% of the lowest price across any physical edition you sell.
• Sales in Brazil, Japan, Mexico, and India require KDP Select enrollment for the 70% rate.
• Sales outside Amazon's approximately 40 eligible 70%-tier territories earn 35% regardless of which plan you chose.

The territory point surprises many authors. You select 70%, but a reader in a non-eligible country buys your book: that sale pays 35%. Amazon shows a blended rate in your dashboard when this happens across your territory mix.

70%-Tier Territory Eligibility

Amazon's eligible territories cover over 40 countries, including the US, UK, Canada, Australia, Germany, France, and most of Western Europe. Sales to countries outside this list (anywhere in Africa, most of South and Southeast Asia, Latin America outside Mexico and Brazil) default to 35%.

If your book targets an international audience and you expect significant non-eligible territory sales, factor in that you'll earn a blended rate lower than 70% on average.

Paperback Royalties: The June 2025 Cliff

Amazon changed its paperback royalty structure on June 10, 2025. Most articles published before that date describe the old structure. The current rules:

• $9.99 and above: 60% of list price minus printing cost
• $9.98 and below: 50% of list price minus printing cost
• Expanded Distribution: 40% of list price minus printing cost

The formula: (royalty rate × list price) − printing cost = net royalty

Paperback Printing Costs (US, Black & White)

Amazon calculates printing costs by page count:

• Up to 108 pages: $2.30 flat
• 110+ pages: $1.00 + ($0.012 × page count)

A 300-page book costs $1.00 + (300 × $0.012) = $4.60 to print.

Worked examples for a 300-page paperback:

The $9.99 threshold creates a sharp discontinuity. A 300-page paperback priced at $9.98 earns 50%: (0.50 × $9.98) − $4.60 = $0.39. The same book at $9.99 earns 60%: (0.60 × $9.99) − $4.60 = $1.39.

A $1.00 price increase nets you $1.00 in additional royalty on every copy. Pricing just below $9.99 for a standard-length paperback is almost always a mistake.

The Cliff Thresholds Across Marketplaces

The pricing cliff is not $9.99 everywhere. By market:

• Amazon.com: $9.98/$9.99
• Amazon.co.uk: £7.98/£7.99
• Amazon.de / .fr / .es / .it: €9.98/€9.99
• Amazon.ca: C$13.98/C$13.99
• Amazon.com.au: A$13.98/A$13.99

If you sell primarily outside the US, check your primary market's threshold.

Expanded Distribution: When It Works and When It Doesn't

Expanded Distribution routes your paperback through Ingram and other wholesalers to non-Amazon retailers and libraries. The 40% rate sounds appealing, but the math is unforgiving for short or low-priced books.

For a 300-page book (printing cost $4.60) via Expanded Distribution at 40%:

• $9.99 list: (0.40 × $9.99) − $4.60 = −$0.61 (negative; Amazon blocks this)
• $11.50 minimum to break even: (0.40 × $11.50) − $4.60 = $0

The minimum viable price formula for Expanded Distribution: printing cost ÷ 0.40

A 200-page book (printing cost: $1.00 + (200 × $0.012) = $3.40) breaks even at $8.50. A 400-page book (printing cost $5.80) needs $14.50 minimum. Enabling Expanded Distribution below the viable price generates zero or negative royalties on those channel sales, which means you're paying for the printing while someone else keeps the retail margin.

Enable Expanded Distribution only when your per-copy royalty at 40% is meaningfully positive: at least $0.75–$1.00 per copy after printing cost.

Hardcover Royalties

KDP hardcovers follow the same 50%/60% threshold as paperbacks (60% at $9.99+, 50% below), but printing costs are higher. A 300-page hardcover costs approximately $5.65 + (300 × $0.012) = $9.25.

Hardcovers are not eligible for Expanded Distribution. They require a minimum of 75 pages.

Worked example: a 200-page hardcover at $19.99.

• Printing cost: $5.65 + (200 × $0.012) = $8.05
• Royalty: (0.60 × $19.99) − $8.05 = $3.94

The same book as a paperback at $19.99:

• Printing cost: $1.00 + (200 × $0.012) = $3.40
• Royalty: (0.60 × $19.99) − $3.40 = $8.59

Hardcover printing costs erode royalties fast. Price hardcovers with this gap in mind, or treat them as a prestige offering rather than a primary revenue driver.

Kindle Unlimited and KENP Page Reads

KDP Select is Amazon's 90-day ebook exclusivity program. Enrollment gives your book access to Kindle Unlimited (KU), where subscribers can borrow and read it for free. Instead of per-sale royalties, you earn per KENP page read (Kindle Edition Normalized Page, Amazon's standardized page unit, which typically runs 1.5× higher than a print page count).

How the KENP Rate Is Set

Amazon publishes a monthly KDP Select Global Fund. Every month, that total is divided among all pages read across every KDP Select title. The per-page rate fluctuates monthly; Amazon publishes the fund size but not the per-page rate directly.

Community-tracked rate data for 2026:

Historical range across 2025–2026: $0.0038–$0.0052 per page. Planning estimate: $0.0045/KENP page. Written Word Media publishes community-compiled KENP rate estimates monthly.

Amazon paid $711.3 million to KDP Select authors in 2025, up 11.2% year-over-year, and over $2.58 billion cumulatively since 2020.

KU vs. Direct Sale: The Math

At $0.0045/page, a full KU read earns far less than a direct sale:

KU only approaches sale value for very long books (700+ pages) at higher price points. Most books earn less per reader in KU than they would at a $4.99–$7.99 sale price.

There is also a 3,000 KENP cap per title per customer per borrow. Amazon pays for at most 3,000 normalized pages of any single book per reader. A 3,500-page epic that a reader re-reads earns royalties for 3,000 pages on the first read; subsequent reads within the same borrow period don't count.

KDP Select Exclusivity Trade-Off

KDP Select enrollment means your ebook can only be sold on Amazon for the 90-day period. You cannot sell it simultaneously on:

• Apple Books
• Kobo
• Barnes & Noble Press
• Google Play Books
• Your own website or Gumroad storefront

Additional KDP Select perks offset the exclusivity for some authors. Kindle Countdown Deals let you sell at promotional prices (including $0.99) while retaining the 70% royalty rate: one of the few exceptions to the $2.99 minimum rule. Free Book Promotions give you up to 5 free days per 90-day enrollment period, useful for list-building.

KDP Select vs. Wide Distribution: Which Fits Your Book

KDP Select works best when your genre has a large KU reader base. Romance, thriller, and genre fiction readers in particular use Kindle Unlimited as their primary reading subscription. If your book fits those categories and you're building readership without an established audience on other platforms, KDP Select is worth testing for at least one 90-day period.

Wide distribution (publishing on Apple Books, Kobo, and other platforms via services like Draft2Digital or direct upload) makes more sense for nonfiction, professional books, and authors with audiences on those platforms. Nonfiction readers often buy on Kobo or Apple Books based on recommendations; the KU subscriber base skews toward fiction consumption.

Neither path is permanent. You can unenroll from KDP Select after 90 days and go wide, or transition from wide to KDP Select for a promotional push. See author earnings for realistic income benchmarks across both distribution strategies.

Payment Timing and Thresholds

KDP royalties are not paid the month you earn them. Standard payment timing:

• Standard ebook and paperback royalties: approximately 60 days after the end of the sale month (January sales → payment in late March)
• Expanded Distribution royalties: approximately 90 days after month-end

Electronic funds transfer (EFT/direct deposit): Amazon pays any amount monthly, with no minimum royalty threshold before funds are released.

Wire transfer or check: minimum thresholds apply and vary by currency and marketplace. Royalties accumulate until the threshold is reached, then are paid. Authors with low initial sales volume should use EFT to avoid royalties sitting idle.

Currency conversion: Amazon pays in the currency of your bank account when possible. UK authors with a GBP account receive GBP payments from Amazon.co.uk without conversion. Authors receiving foreign currency payments bear Amazon's embedded conversion rate, which is typically a few percentage points below the mid-market rate.

Tax Treatment of KDP Royalties

This section covers general information about US tax treatment. Consult a qualified tax professional for advice specific to your situation.

US Authors

Amazon treats KDP royalties as self-employment income by default, reported on Schedule C and subject to both income tax and self-employment tax (15.3% on net earnings up to the Social Security wage base). Amazon issues Form 1099-NEC to US authors earning $600 or more in a calendar year.

Business expenses are deductible: editing, cover design, advertising, publishing software, and a portion of a home office used exclusively for writing.

Some tax advisors treat recurring royalty income as Schedule E passive income, which avoids self-employment tax. This distinction has significant financial impact depending on the nature of the author's involvement. A tax professional familiar with self-publishing income can determine which treatment applies.

Non-US Authors: The W-8BEN Gap

Non-US authors face a 30% US withholding tax on royalties by default under IRC §881 (FDAP income). Amazon withholds 30% before you receive payment.

Most countries have tax treaties with the US that reduce or eliminate this withholding. To claim the reduced rate, you must complete Form W-8BEN (for individuals) or W-8BEN-E (for entities) through the KDP Tax Interview process. Treaty withholding rates by country:

Most European Union countries have 0% treaty rates on royalties. Submit your W-8BEN before you reach the payment threshold; it applies prospectively, not retroactively. Once approved, Amazon withholds at the treaty rate, not the 30% default.

Without a W-8BEN: a non-US author earning $1,000 in royalties in a country with a 0% treaty rate keeps $700. The same author with a valid W-8BEN on file keeps $1,000. Submit the form during account setup.

KDP vs. Traditional Publishing Royalties

Publishing directly on KDP versus through a traditional publisher involves different royalty structures, advance mechanisms, and risk profiles:

The per-copy royalty comparison strongly favors KDP for ebooks. A $9.99 ebook earns about $6.89 on KDP versus roughly $1.74 through a traditional publisher at 25% of net receipts.

The comparison is incomplete without two important caveats. Traditional publishers provide a cash advance against future royalties: you receive money before the book earns it back. They also provide physical bookstore distribution, editorial infrastructure, and marketing reach that self-publishers must build or buy independently.

KDP provides none of that, but gives you direct control over pricing, timeline, and royalty rates. Most authors publishing on Kindle choose KDP specifically to capture the higher per-copy margin and retain creative control.

KDP vs. Other Ebook Platforms

For authors considering wide distribution alongside or instead of KDP Select, the main competitors' royalty structures:

Amazon's July 2026 ceiling increase closes the gap on the ceiling advantage Apple, Kobo, and B&N Press had at price points between $10.00 and $12.99. The per-MB delivery fee remains the primary structural difference: the other major platforms charge nothing for file delivery, which means a 10 MB illustrated ebook earns the same per-copy rate as a 0.5 MB novella.

Common KDP Royalty Mistakes

Pricing Below $2.99 Without Knowing the Cost

Authors new to KDP sometimes price at $0.99 or $1.99 to attract readers. At those prices, the 70% tier is unavailable: you earn 35% of your list price, or $0.35 and $0.70 respectively.

The logic of "sell more copies at a low price" fails to account for how much volume is needed to offset lower per-copy earnings. A book priced at $4.99 earning 70% ($3.39/copy) needs 10 copies sold to match the revenue of 34 copies sold at $0.99. Use $0.99 pricing tactically for launch promotions, then reprice.

Ignoring the $9.99 Paperback Cliff

Pricing a paperback at $9.95, $9.97, or $9.98 to feel more affordable costs you 10 royalty percentage points on every copy. For a 300-page paperback, that's $1.00 less per copy. At 100 copies sold, that's $100 in lost royalties from a pricing decision that could be fixed in two minutes.

Enabling Expanded Distribution Before Checking the Math

The 40% Expanded Distribution rate sounds like free additional sales. For many books, the math produces zero or negative royalties on expanded-channel copies.

Calculate your breakeven price (printing cost ÷ 0.40) before enabling it. If your list price is below that breakeven, you're subsidizing expanded-channel sales.

Skipping the W-8BEN as a Non-US Author

Non-US authors who skip the KDP Tax Interview and W-8BEN setup pay 30% withholding on every royalty payment. For an author with a 0% treaty rate, this is entirely avoidable. Complete the Tax Interview during account setup; it takes about 10 minutes and applies to all future payments.

Not Compressing Large Ebook Files

Authors who export illustrated books or PDFs with print-resolution (300 DPI) images end up with 15–30 MB ebooks. At $0.15/MB, a 20 MB file incurs a $3.00 delivery fee, which can flip the math to favor 35% over 70% at low price points. Compress images to 72–150 DPI for screen viewing before Kindle conversion.
