Most UK authors ask the same question when they think about self-publishing income: “What’s realistic?” The honest answer is that earnings vary wildly. Some authors make enough to support themselves; many earn far less. The difference often isn’t talent. It comes down to expectations, numbers and knowing how royalties, pricing and costs actually work for self-published authors in the UK.
How royalty rates and pricing shape self-publishing income
If you self-publish through Amazon Kindle Direct Publishing (KDP), you must choose between two royalty rates: 70% or 35%. The rate depends on the price you set for your ebook. As of 2025, ebooks priced in the UK between £1.77 and £9.99 qualify for the 70% royalty. Outside that range, the 35% rate applies. Delivery fees based on file size apply to the 70% option and reduce earnings slightly. The UK has zero-rated ebooks for VAT since May 2020, so your list price includes no VAT.
For print books sold through Amazon via KDP, royalties follow KDP’s June 2025 royalty structure. Higher-priced paperbacks earn 60% of the list price minus printing costs, while lower-priced titles earn 50%. Printing is print-on-demand. For example, consider a 300-page paperback priced at £9.99, which earns the 60% rate. If it costs £4 to print, it returns roughly £2 per copy before other costs.
You will need to set your ebook price carefully. Pricing at £2.99 puts your book into the 70% bracket, provided it meets the pricing requirements. Moving up towards £9.99 keeps you at the top of that band. However, you risk fewer sales if the genre or demand does not support that price.
The upfront costs you need to budget for
To understand your net income, you must subtract costs. Key costs include:
- Editing and proofreading: often £500 to £1,500 for a full-length book.
- Cover design: £300 to £600 for a professional designer, sometimes more for a rebrand.
- Formatting and interior layout: £80 to £150 depending on complexity.
- ISBNs (for print and wide distribution): around £93 for a single ISBN from Nielsen, the UK ISBN agency.
- Marketing and advertising: anywhere from £100 to several thousand pounds depending on ambition.
Suppose you spend £1,000 on editing, cover, formatting and marketing, and earn £3 per ebook sale. You would need roughly 334 ebook sales just to break even. That assumes you sell at the 70% rate. With print, per-unit returns depend heavily on your list price and printing cost.
What median earnings really look like
A large 2022 survey of UK authors looked at “primary occupation authors”, meaning those who spend at least half their working time on writing. Their median self-employed income from writing was £7,000 per year. That marks a significant drop from £11,329 in 2018.
Only 19% of those primary occupation authors reported that all their income came from writing. Many authors combine book earnings with day jobs, workshops, freelancing or speaking.
Other industry research tells the same story. The ALCS authors’ earnings survey in 2018 put the median annual income from writing alone at £10,497, just under £10,500. That figure spans traditionally published and self-published authors, and incomes have fallen further since. It implies that many self-published authors sit well below that level.
When authors earn more: genre, backlist and scale
Some authors do much better than the median. Genres with strong ebook demand, such as romance, thriller and speculative fiction, often generate higher sales volumes. Authors who publish multiple books and maintain consistent output tend to scale more quickly. A well-marketed backlist of several titles priced between £2.99 and £4.99 can, once it gains “long tail” traction, bring in £10,000 to £20,000 or more a year. These figures are illustrative rather than survey data, but they show how the maths can work in your favour once per-sale margins compound across a catalogue.
Treat the success stories with care. Some full-time self-published authors in the UK report earning £20,000 to £60,000 a year after several years of consistent output. These cases are rare, and they almost always involve frequent releases, an engaged readership and extra income streams such as audiobooks, courses or merchandise. They are the visible tip of a very large iceberg.
The costs authors forget: tax, time and the gender pay gap
Many self-published authors overestimate income because they ignore:
- Returns, discounts and free promotions
- The hours of writing, editing and marketing that amount to unpaid labour
- Tax and National Insurance: royalties and print profits count as self-employment income and must be reported to HMRC. If your turnover grows, it is worth understanding whether to operate as a sole trader or set up a company. Our guide to sole trader vs limited company explains the trade-offs.
- The gap between net revenue and what lands in your bank after platforms take fees and delivery charges
There is also a gender gap that matters for our readers. In the 2022 authors’ survey, women earned about 41.4% less than men from their writing. The survey does not explain the gap, but likely contributors include genre mix, unpaid caring responsibilities and the time authors can afford to spend on marketing. Either way, it strengthens the case for treating self-publishing as a business, with disciplined pricing and more than one income stream, rather than a lottery.
What this means for UK authors
If you’re planning your self-publishing business or side hustle, here is what you should expect and plan for:
- Budget realistically. Your first book may lose money. Set aside funds for editing, design and launch. Calculate your break-even point: divide total upfront cost by what you earn per copy.
- Choose pricing with care. Use pricing bands that hit the 70% royalty rate for ebooks. Know what your genre supports.
- Build a catalogue. One book rarely changes income; several books can provide residual income. But you must keep output consistent and maintain quality.
- Diversify income. Combine book sales with marketing (social media, newsletter), audiobook rights, speaking, merchandise or courses.
- Monitor contracts, rights and taxes. Retain rights where possible. Report self-published earnings properly as trading income if writing is more regular. Seek advice on copyright, reversion clauses and similar issues.
Self-publishing can offer UK authors margins on individual sales that traditional publishing cannot match. But it comes with risks, fluctuating income, high upfront effort and often low median returns. Expect modest returns at first. Breaking even in the early years is a realistic goal. Earning £7,000 a year, the median for primary occupation authors, is a sensible milestone. Tens of thousands annually is possible for established authors with sizeable catalogues. Go in with your eyes open: the authors who succeed are the ones who treat it as a business from day one.
