Amazon KDP pays 35–70%. Traditional UK publishers typically pay 7.5–15%. An honest breakdown, in pounds, of what independent authors actually earn and how to maximise your income.
Royalty rates are the most frequently misunderstood number in publishing. Authors see '70% royalty' and assume they will earn 70p of every pound readers spend. The reality involves several layers of calculation that every UK author should understand before pricing a book or choosing a distribution platform.
How Amazon KDP Royalties Work in the UK
Amazon KDP offers two royalty tiers for ebooks: 35% and 70%. On Amazon.co.uk, the 70% tier applies to ebooks priced between £1.77 and £9.99; books priced outside that range earn 35%. Because ebooks are zero-rated for VAT in the UK, no VAT is deducted from a UK list price before your royalty is calculated.
The 70% is calculated on the list price minus a small 'delivery cost' based on file size (around 10p per megabyte on Amazon.co.uk). For a standard novel ebook this is usually just a few pence per sale.
Example: a £2.99 ebook on Amazon.co.uk at 70% royalty earns about £2.05 per sale after delivery costs. Sell 1,000 copies and you earn around £2,050.
Print Royalties: Where the Maths Gets More Complex
Print royalties are calculated differently from ebook royalties. The formula is: (List Price × Royalty Rate) − Print Cost = Author Royalty. KDP pays 60% on most paperbacks sold through Amazon (a lower rate applies to cheaper books), and printing a 300-page B&W paperback in the UK costs roughly £4.45.
| Book Price | Print Cost (300 pp) | KDP Royalty (60%) | Net to Author |
|---|---|---|---|
| £9.99 | £4.45 | £5.99 | £1.54 |
| £10.99 | £4.45 | £6.59 | £2.14 |
| £11.99 | £4.45 | £7.19 | £2.74 |
| £12.99 | £4.45 | £7.79 | £3.34 |
This shows why pricing a paperback too low can result in near-zero royalties, or even a loss through some channels. Many UK indie authors price 300-page paperbacks between £9.99 and £12.99 to earn a meaningful margin while staying competitive with traditionally published titles.
Traditional UK Publishing Royalty Comparison
Traditional publishers pay royalties as a percentage of either the recommended retail price (RRP) or the net receipts (what the publisher receives after the retailer's discount). This distinction matters enormously, because UK retailers often buy at discounts of 50% or more.
- Hardback: typically 10% of RRP, rising to 12.5% and then 15% after agreed sales thresholds
- Paperback: typically 7.5% of RRP, sometimes rising to 10%
- High-discount sales (supermarkets, book clubs, deep-discount online): often a lower royalty calculated on net receipts
- Ebook: typically 25% of net receipts, which works out at roughly 12–17% of the retail price
- Audiobook: typically 20–25% of net receipts
What Authors Actually Earn: Realistic Scenarios
| Scenario | Annual Sales | Avg. Royalty/Copy | Annual Income |
|---|---|---|---|
| Trad. pub ebook | 2,000 | £0.50 | £1,000 |
| Self-pub ebook (KDP, £2.99) | 2,000 | £2.05 | £4,100 |
| Trad. pub paperback (£9.99 RRP) | 2,000 | £0.75 | £1,500 |
| Self-pub paperback (£11.99) | 2,000 | £2.74 | £5,480 |
| Self-pub ebook + print | 2,000 each | £2.05 + £2.74 | £9,580 |
Maximising Your Royalty Income
The most effective strategies for increasing royalty income follow a clear pattern among high-earning self-published authors:
- Publish in series: reader retention from book one to book two is often 60–80% for well-written series, and each new release reactivates the whole backlist.
- Build an email list: direct sales through your own shop (Payhip, Shopify or WooCommerce) can return 90–95% of the sale price, far more than any retailer.
- Price book one of a series at 99p or free as an entry point, then earn full price on books two and three.
- Enrol in Kindle Unlimited (KDP Select) if your audience is avid genre readers; page reads can add significantly to monthly income for romance, thriller and fantasy authors.
- Publish in multiple formats: ebook, paperback, hardback and audiobook each reach different readers.
- Collect UK extras: register for Public Lending Right (PLR) to be paid when libraries lend your book, and join ALCS for secondary royalties.
Don't Forget Tax
Royalties are taxable income in the UK. Most self-publishers register as self-employed and file through HMRC Self Assessment, and the £1,000 trading allowance may cover very small earnings. On US platforms such as KDP, complete the W-8BEN tax interview so that no US tax is withheld from your royalties under the UK–US tax treaty.
The Bottom Line
Self-published authors typically earn several times more per copy sold than their traditionally published peers. The ceiling is higher too: the most successful UK indie authors earn six-figure incomes from book sales alone. Reaching that tier takes volume (multiple titles), quality (professional production) and marketing (consistent audience building), but the royalty structure makes it achievable without a publishing deal.
