What is an author royalty and how much do authors earn?
An author royalty is the payment an author receives per sale or per page read. Self-publishers on Amazon KDP earn 35% or 70% of list price depending on tier; other retailers like Apple Books and Kobo pay up to 70%. Traditional publishers typically pay 7.5–15% on print and 25% of net on ebooks. Royalties are paid monthly ~60 days after the sale month ends.
An author royalty is the payment an author receives each time their book sells or is read. In self-publishing, royalties are calculated as a percentage of the list price (minus costs), paid monthly by the retailer or distributor. In traditional publishing, they're negotiated in the author's contract — typically 10–15% of list on hardcovers, 7.5–10% on paperbacks, and 25% of net receipts on ebooks.
Amazon KDP is where most indie royalty revenue happens. KDP's royalty policy offers two tiers:
Other retailers:
If your book is enrolled in KDP Select, Kindle Unlimited subscribers can read it for free and you earn per KENP (Kindle Edition Normalized Page) read — currently $0.004–$0.005 per page. A 300-page novel fully read pays out roughly $1.20–$1.50 per reader. For genre fiction authors with deep catalogs, KU page-read revenue often exceeds direct unit sales.
Non-US authors publishing on Amazon KDP have 30% of royalties withheld by default. Filing a W-8BEN with treaty benefits (UK, Canada, Australia, most of Europe) reduces this to 0–15%. This is the single most common money-losing mistake first-time international authors make. Fix it before your first royalty payment.
Amazon KDP pays ~60 days after month-end: January earnings hit your account end of March. Apple Books is similar. Some aggregators (D2D, PublishDrive) consolidate all retailer royalties into a single monthly payment, which simplifies tax reporting.
Example 1: Indie genre novelist. 8-book romance series, all enrolled in KDP Select, priced $3.99 per book. Split: direct unit sales at 70% tier = $2.73/unit. KU page reads at $0.0045 × 280 pages × 500 readers/month across the catalog = $630/month. Total: ~$1,800/month from unit sales + $630 from KU = $2,430/month. Scale this to 4 series over 3 years = $29k/year.
Example 2: Business non-fiction. Single 180-page guide priced $9.99 in the 70% tier ($6.93 royalty per unit after $0.06 delivery fee). 100 units/month = $693 on Amazon. Adds Apple Books (70% flat, ~15 units/month = $105), Gumroad direct sales ($7.50 per unit after Stripe, 20/month = $150). Total: $948/month wide, versus ~$700/month if Amazon-exclusive.
Example 3: Premium-priced consultant book. 240-page authority report priced $29.99. At this price, only the 35% tier applies ($10.50 royalty per unit). 20 units/month on Amazon = $210/month direct. But the book's real purpose is generating consulting leads — the $10.50 unit royalty is incidental; the $8,000 consulting engagements from book readers are the actual revenue stream.
Other concepts you'll encounter alongside this one.
Longer-form resources that apply this concept in practice.
Price range and delivery fee. 70% is available at $2.99–$9.99 with a tiny delivery fee (~$0.06 per book); 35% works at any price from $0.99 to $200 with no delivery fee. For most indie ebooks, 70% at $4.99–$7.99 produces the best per-unit earnings.
Per unit, dramatically more — self-pubs earn $3–$7 per ebook vs $0.50–$2 for trad-pub authors after agent commission. But trad-pub offers advances, marketing support, bookstore distribution, and prestige press placements. Per-title revenue often favors self-pub for genre fiction and non-fiction; trad-pub still wins for literary fiction and high-prestige non-fiction.
~60 days after month-end. January royalties pay out end of March via ACH (US) or EFT (international). Minimum payout threshold is $100 or equivalent in your local currency — Amazon rolls smaller balances forward.
A 300-page novel fully read in KU pays ~$1.20–$1.50 (at $0.004–$0.005/KENP). Same book sold direct at $4.99 in the 70% tier pays $3.40/unit. Unit royalty is higher per transaction but KU readers are often readers who wouldn't have bought anyway — so KU revenue is usually additive, not cannibalistic.
Amazon withholds 30% from non-US sellers by default. File a W-8BEN in your KDP account and claim your country's tax treaty benefit (UK: 0%, Canada: 0%, Australia: 5%, most EU: 0%). This single-form fix often recovers $2,000–$20,000/year for mid-tier international indie authors.
