Worked examples
Three real scenarios, fully calculated
The same book earns wildly different royalties depending on format and platform. Here's what the numbers actually look like.
A $4.99 ebook on Amazon KDP
Setup: Format: ebook. List price: $4.99. KDP falls inside the 70% royalty window ($2.99 to $9.99).
Royalty math
$4.99 × 70% = $3.49. Subtract an approximate $0.15 delivery fee for a 1MB file → $3.34 per sale.
Takeaway: At 50 sales per month that's $167 per month from a single ebook on Amazon. Stack 5 books and it's real part-time income.
A 250-page paperback at $14.99 via KDP
Setup: Format: paperback (6x9 B&W). List price: $14.99. Page count: 250.
Royalty math
Print cost = $1.00 + ($0.012 × 250) = $4.00. Royalty = (60% × $14.99) − $4.00 = $8.99 − $4.00 = $4.99 per sale.
Takeaway: Paperbacks feel premium to buyers and earn more per sale than ebooks, but the volume is usually lower. Ideal as a companion to an ebook on KDP.
The same paperback on IngramSpark (default 55% discount)
Setup: Same 250-page book at $14.99 on IngramSpark with the default 55% wholesale discount for bookstore reach.
Royalty math
Print cost ≈ $2.00 + ($0.015 × 250) = $5.75. Royalty = (45% × $14.99) − $5.75 = $6.75 − $5.75 = $1.00 per sale.
Takeaway: IngramSpark pays a much thinner margin, but it's the only way to reach independent bookstores, libraries, and international retailers. Hybrid authors often do KDP for Amazon + IngramSpark for everywhere else.
Once you know what each platform pays, the next question is where to list. Most indie authors put ebooks on Amazon KDP and decide about print after looking at the numbers above. Our self-publishing guide walks through the full launch workflow including cover design, formatting, and metadata.
How each platform pays
Royalty formulas, explained
Every platform has its own quirks. Here are the rules the calculator uses, with links to the official royalty documentation on each.
Amazon KDP (ebook)
Amazon pays 70% on ebooks priced $2.99 to $9.99 (minus a small per-MB delivery fee) and 35% outside that range. The 70% tier is the single most important pricing decision most self-publishers make.
Formula
70% if list price is $2.99 to $9.99, otherwise 35%. Delivery fee ~$0.06 per MB on the 70% tier only.
Amazon KDP (paperback)
Fixed 60% royalty on paperbacks, minus the print cost Amazon charges to produce each copy. Royalty is positive only if your list price covers print cost plus margin, so low page counts at high prices earn the most.
Formula
60% × list price − print cost. Print cost ≈ $1.00 fixed + $0.012/page (B&W) or $0.065/page (colour) for a standard 6x9 trim.
Amazon KDP (hardcover)
Same 60% royalty formula as paperback, but with a higher print cost per copy because of the case-laminate binding. Typical minimum list price to break even sits around $13 to $15 for a standard-length book.
Formula
60% × list price − print cost. Print cost ≈ $6.80 fixed + $0.023/page (B&W) on a 6x9 case-laminate hardcover.
IngramSpark (print)
Worldwide print distribution into bookstores and libraries. You set a wholesale discount (default 55%), meaning bookstores keep 55% of list and you get 45% minus print cost. Higher discount = wider distribution, thinner royalty.
Formula
(1 − wholesale discount) × list price − print cost. Default: 0.45 × list − print cost. Print cost ≈ $2.00 + $0.015/page (6x9 B&W paperback).
Kobo Writing Life (ebook)
Kobo's direct author program pays 70% on ebooks priced $2.99 and up, 45% on anything lower. Simpler than KDP: no delivery fee, no price-zone adjustments, and no KDP Select exclusivity requirement.
Formula
70% if list price is $2.99 or higher, otherwise 45%. No delivery fee.
Apple Books (ebook)
Apple Books pays a flat 70% royalty on every ebook sale at any price point, including free and very low-priced books. No delivery fee, no price-banding, no Select exclusivity requirement.
Formula
70% × list price at every price point. No delivery fee.
Google Play Books (ebook)
Google Play pays partners 52% of list price on ebook sales. A lower headline rate than Kobo or Apple, but Google Play reaches search-driven readers that other stores don't touch, especially outside the US.
Formula
52% × list price on ebook sales.
Draft2Digital (aggregator)
Distributes your ebook to Apple, Kobo, Barnes & Noble, Google Play, and dozens of other stores. D2D charges no upfront fee and keeps about 10% of the net royalty the retailer pays you. Good for reach without juggling seven dashboards.
Formula
Approximately 60% × list price after retailer and D2D cuts, averaged across retailers.
In the platforms' own words
What the royalty pages actually say
The formulas in this calculator aren't interpretation. They're straight from the official royalty documentation of each platform.
"You can earn 70% royalty on sales to customers in eligible countries of eBooks priced between $2.99 and $9.99."
"Kobo Writing Life offers 70% royalties on eBooks priced $2.99 USD and above, and 45% on eBooks priced below that."
"Apple Books shares 70% of the sale price with you on every eBook sold."
Pricing strategy
Royalty math is one half. Pricing is the other.
Two books at different price points earn wildly different amounts even at the same royalty rate. The right list price depends on genre, length, and how you're positioning the book.
Most first-time self-publishers make one of two pricing mistakes: they price too low (thinking $0.99 will pull more buyers, which also drops them out of the 70% royalty tier and costs them money per sale) or they price too high (pricing a novel at $14.99 in a genre where $3.99 is the norm, and watching it fail to sell). Neither mistake is fatal, but both cost real income. Pricing also compounds with presentation: a sharp, on-genre title (run the free title ideas tool if yours feels flat) raises click-through enough to move the per-sale math meaningfully.
Genre benchmarks in 2026: fiction novels usually price $2.99 to $5.99 on ebook. Non-fiction and business books price higher at $4.99 to $9.99 because buyers treat them as reference material. Short fiction novellas can price $0.99 to $2.99 at the 35% royalty rate to pull readers into a longer series. Lead magnets typically price free. Full-length paperbacks price $9.99 to $16.99.
The 70% tier matters more than most authors realise. A novel priced at $2.99 earns $2.05 per sale. The same novel priced at $2.98 earns $1.04. That one-cent difference halves your royalty because the book falls out of the 70% royalty window. If you're within 10 cents of the boundary, check which side you're landing on. The official KDP royalty page lists the exact boundaries.
Print royalties depend on page count. A 200-page paperback at $9.99 earns $5.99 × 60% = $3.59 minus $3.40 print cost = $0.19 per sale. The same paperback at $14.99 earns $4.99 per sale. Print-on-demand economics punish low list prices on thick books. Our AI book formatter helps hit a target page count when you need to price at a specific point.
Bundle ebook + paperback + audiobook for maximum revenue per reader. A reader who buys your paperback at $14.99 doesn't compete with a reader who buys your ebook at $4.99. They're often the same person buying the same book twice, in different formats, for different contexts. Converting your book to audio through the AI audiobook generator opens a third revenue stream at $12.99 to $24.95 per audiobook on Audible.
Context
What royalties actually look like in 2026
Real-world numbers from the latest published author income surveys and platform documentation.
Median self-published income: approximately $12,800 per year, with the top 10% earning over $100,000 and most authors under $10/month. (ALLi Author Income Survey)
KDP's 70% window: $2.99 to $9.99 is the single most important price range in self-publishing. 85% of top-1000 indie ebooks sit inside it. (Amazon KDP)
Print-on-demand economics: KDP and IngramSpark both print each copy on demand. No upfront inventory cost, no warehousing, royalty deducted at the moment of sale. (IngramSpark)

Frequently Asked Questions
Everything authors ask before pricing a launch.
How do I calculate book royalties?
Multiply your list price by the platform's royalty rate, then subtract any print or delivery costs. For an ebook on KDP priced at $5.99, the formula is $5.99 × 70% minus a small delivery fee (about $0.15), giving roughly $4.04 per sale. For a paperback, use 60% × list price − print cost, where print cost is $1.00 plus $0.012 per page. Our calculator does this automatically across every major platform.
What is the 70% royalty tier on Amazon KDP?
Amazon pays 70% royalty on ebooks priced between $2.99 and $9.99. Outside that range, you earn 35%. The 70% tier also charges a delivery fee of roughly $0.15 per megabyte, which usually works out to about $0.06 to $0.45 per sale depending on your book's file size. Most self-publishers target this range to maximise revenue per sale.
Which publishing platform pays the highest royalty?
Apple Books pays a flat 70% at every price point, which is the simplest and often highest headline rate. Kobo Writing Life pays 70% above $2.99 with no delivery fee (slightly better than KDP at small file sizes). Amazon KDP pays 70% only in the $2.99 to $9.99 window. For print, the highest rate is KDP at 60% minus print cost; IngramSpark pays 45% minus print cost but reaches bookstores and libraries that KDP doesn't.
How much does Amazon KDP print cost per book?
For a standard 6x9 paperback in black-and-white, print cost is approximately $1.00 fixed plus $0.012 per page. A 200-page paperback costs about $3.40 to print, a 300-page paperback about $4.60. Colour interior is much more expensive at $0.065 per page. Amazon deducts this from your royalty on every sale.
What is the minimum price for a KDP paperback to make money?
Your minimum viable list price is print cost divided by 60% (the royalty rate). A 200-page paperback costs about $3.40 to print, so the minimum list is roughly $5.67 ($3.40 / 0.60). In practice, most self-publishers price paperbacks between $9.99 and $14.99 for healthy margins. Our calculator flags unprofitable combinations in red.
How does IngramSpark royalty compare to KDP?
IngramSpark pays a lower royalty rate (45% at default 55% wholesale discount vs KDP's 60%) but gives you access to the Ingram distribution network: independent bookstores, libraries, and international retailers that KDP Print doesn't reach. Many self-publishers use KDP for Amazon sales and IngramSpark for everywhere else. Printing costs are broadly similar.
Do I pay taxes on book royalties?
Yes. Book royalties are taxable self-employment income in most jurisdictions. In the US, Amazon and other platforms issue a 1099 form if you earn over the reporting threshold ($600 in 2026). In the UK, royalties are typically reported as self-employment income via Self Assessment. Check your local tax authority. The IRS publishes guidance on royalty income at irs.gov (Schedule E for passive royalties, Schedule C if writing is your business).
Can I publish on KDP and IngramSpark at the same time?
Yes, for print books. You publish the ebook on KDP (or wherever) and the paperback on both KDP for Amazon and IngramSpark for everywhere else. Most hybrid authors use this setup. Important: do not enrol your ebook in KDP Select (Kindle Unlimited) if you also distribute ebooks elsewhere, because Select requires ebook exclusivity for 90 days.
How much do self-published authors earn per month?
The Alliance of Independent Authors' 2024 income survey found the median self-published author earned approximately $12,800 annually, with the top 10% earning over $100,000. The distribution is extremely skewed: most authors earn under $10/month, while a small minority earn six figures. Royalty rate matters less than sales volume, and sales volume is driven by genre fit, cover, blurb, and consistent publishing cadence.
What royalty do aggregators like Draft2Digital pay?
Draft2Digital (and Smashwords, which D2D now owns) takes about 10% of the net royalty the retailer pays, resulting in a blended rate around 60% of list price across stores. PublishDrive and StreetLib operate on similar terms. The trade-off: one dashboard, one tax form, and broader reach in exchange for a thinner margin on each sale vs direct publishing.
How do I price my ebook for maximum earnings?
The sweet spot on KDP is $2.99 to $9.99 for the 70% royalty tier. Within that band, higher prices increase per-sale earnings but often reduce volume. Genre benchmarks: non-fiction typically prices $4.99 to $9.99, fiction novels $2.99 to $5.99, short novellas $0.99 to $2.99 (at the 35% rate). Test two or three price points over four-week windows and measure total revenue, not just per-sale royalty.
Are there hidden fees in book royalties?
A few to watch: KDP's 70% tier charges a delivery fee per megabyte (ebooks with heavy images lose more to this). IngramSpark charges a setup fee per title ($49 for paperback, $49 for hardcover, waived under some promo codes). Subscription audiobook platforms often take a different royalty share than ebooks. Always read the current royalty help pages at the platform before committing.
How does KDP Select / Kindle Unlimited royalty work?
KDP Select is an optional 90-day exclusivity programme. In exchange for not distributing your ebook elsewhere, Amazon enrols you in Kindle Unlimited and pays a 'per-page-read' rate from the global KDP Select fund. The 2026 rate averages around $0.004 to $0.0048 per page read. A 300-page book read cover-to-cover earns roughly $1.20 to $1.44, compared to $2.10 to $4.89 on a direct purchase. Select works best for series authors; less well for standalone premium-priced titles.
Do AI-generated books qualify for the same royalty rates?
Yes. Amazon KDP, Apple Books, Kobo, IngramSpark, and other platforms apply the same royalty rates to AI-generated and human-written books. What changes is the disclosure requirement: KDP asks whether content is AI-generated or AI-assisted at the title-creation step, but this does not affect the 70% royalty tier eligibility or KDP Select enrollment. Our full walkthrough is on the Amazon KDP AI disclosure policy guide.
How does the calculator handle currency?
The calculator assumes USD pricing and USD royalty. Amazon KDP, Kobo, Apple Books, and Google Play each set separate list prices per country in local currency. Royalty rates are consistent across territories (70% / 35% on KDP, 70% on Apple) but the print costs and delivery fees vary. Use the official KDP pricing calculator for exact country-level royalty once your book is live.
