Self-publishing a book can cost almost nothing if you do most of the work yourself and use free tools, or several thousand dollars once you pay for professional editing, a custom cover, an ISBN block and an audiobook. Most of the money goes on editing, which is priced by the word, so the length of your manuscript matters more than anything else. The platforms themselves, such as Amazon KDP, Kobo Writing Life and Draft2Digital, mostly earn from sales rather than upfront fees, though Draft2Digital now charges new accounts a small activation fee.

This guide includes a few product links near the end. As an Amazon Associate, Freyja Publishing earns from qualifying purchases, at no extra cost to you.

This guide breaks the budget into its real cost categories, shows what published rate guides say at the time of writing (October 2026), explains how ISBN costs differ by country, and gives you three budget scenarios you can adapt. Prices change, so treat every figure here as a starting point to check, not a quote.

• Editing is the biggest line item. It is usually priced per word, so a long novel costs far more to edit than a short guide.
• ISBN costs depend on where you live. They are free in Canada and New Zealand, and paid in the US, UK and Australia.
• Uploading to the main stores is free or close to it. Retailers take a share of each sale instead.
• Marketing and audio are optional, open-ended costs. Set a cap before you start.
• Spend where readers notice: editing and the cover first, extras later.

At a glance

• Self-publishing can cost almost nothing with free tools, or several thousand dollars with professional services.
• Editing is the biggest line item and is priced per word, so a 70,000-word novel costs far more to edit than a short guide.
• The EFA’s 2026 chart lists fiction copyediting at a median 2.0 to 2.7 US cents per word.
• ISBNs are free in Canada and New Zealand but paid in the US, UK and Australia.
• Spend first on editing and the cover, and set a marketing cap before you spend anything.
• Avoid paying for a proofread before the structure is settled, and be wary of companies selling large upfront packages.

What you are actually paying for

Every self-published book goes through the same stages, whether you pay someone for each one or do it yourself. Knowing the stages helps you decide where your money makes the biggest difference.

Cost category	Can you do it free?	How it is usually priced	Priority
Developmental editing	Partly (beta readers, critique partners)	Per word or per hour	High for first books and complex fiction
Line editing and copyediting	Partly (careful self-editing, software checks)	Per word or per hour	High
Proofreading	Partly	Per word or per page	High
Cover design	Yes, with design tools and practice	Flat fee per cover or package	Very high
Interior formatting	Yes (free platform tools)	Flat fee, per word or software licence	Medium
ISBNs	In some countries, or via a platform’s free ISBN	Per ISBN or per block	Depends on your plans
Proof and author copies	No	Print cost plus shipping and tax	Medium
Marketing	Yes (organic methods)	Per promotion, per click or per campaign	Variable
Audiobook	Partly (self-narration, digital narration)	Per finished hour or royalty share	Optional

Editing: the cost that varies most

Editing is not one service. It is a sequence, and you may not need every step. If you are unsure which kind you need, the guide to finding the right editor explains how to match an editor to your manuscript.

The main types of editing

• Developmental (structural) editing looks at the big picture: plot, pacing, structure, argument and character. It comes first, because there is no point polishing sentences you may cut.
• Line editing works on the sentence level: rhythm, clarity, word choice and voice.
• Copyediting corrects grammar, spelling, punctuation, consistency and style.
• Proofreading is the final check of the formatted pages for typos and layout errors.

What published rate guides show

The most widely cited public benchmark is the Editorial Freelancers Association (EFA) rate chart. Its 2026 chart is based on a survey of members about the rates they charged during the 2025 calendar year. The figures are median ranges in US dollars, the EFA states that it does not set rates, and individual rates vary considerably. Editors in other countries, and editors with specialist experience, may charge differently.

At the time of writing (October 2026), the EFA chart lists these median ranges for fiction:

Service (fiction)	Median range per word	Median range per hour
Developmental editing	3.0 to 3.5 US cents	US$52.50 to US$70.00
Line editing	2.7 to 3.5 US cents	US$50.00 to US$60.00
Copyediting	2.0 to 2.7 US cents	US$40.00 to US$50.00
Proofreading	1.2 to 2.0 US cents	US$35.00 to US$45.00
Formatting	1.1 to 1.4 US cents	US$52.50 to US$67.50

The same chart shows higher ranges for non-fiction than fiction across the main editing types. For example, non-fiction copyediting is listed at 3.0 to 4.0 US cents per word, and non-fiction developmental editing at 4.0 to 5.0 US cents per word. Prices change, so check the current chart before you budget.

A worked example: a 70,000-word novel

Multiplying the EFA fiction ranges by 70,000 words gives a rough idea of scale. This is simple arithmetic from the chart, not a quote from any editor:

• Developmental editing: about US$2,100 to US$2,450
• Line editing: about US$1,890 to US$2,450
• Copyediting: about US$1,400 to US$1,890
• Proofreading: about US$840 to US$1,400

Few authors buy all four at full rates for every book. Many combine self-editing and beta readers with one or two paid passes, most often a copyedit and a proofread. Some editors offer a combined line and copyedit. Ask what each quote includes, how many passes, and whether a second read is included after you make changes.

Cover design

The cover is your book’s main advertisement on a store page, where it often appears as a small thumbnail. There is no independent published rate chart for cover design comparable to the EFA’s, so this guide does not quote prices. In general terms, the options from least to most expensive are:

1. Do it yourself with a design tool and licensed images. The cost is your time plus any image licence fees.
2. Premade covers, where a designer sells a finished design and adds your title and name. These are usually far cheaper than custom work.
3. Custom ebook covers designed for your book alone.
4. Custom full wraps for paperback and hardcover, which need a spine and back cover sized to your page count. These cost more than an ebook front alone.
5. Illustrated covers, common in fantasy and children’s books, which usually cost the most because of the artwork.

Check exactly what you receive: print-ready files, the image licence terms, and whether you can reuse the design for adverts. The guide to choosing a professional book cover designer covers the questions to ask.

Interior formatting

Formatting turns your manuscript into an ebook file and a print-ready PDF. This is where the free options are strongest. Amazon offers Kindle Create, and Draft2Digital’s formatting and conversion tools are free to use, including downloading the converted files, even if you do not distribute through it. Paid formatting software is a one-off or subscription cost, and a professional formatter is worth considering for complex layouts such as cookbooks, textbooks or illustrated books.

For a straightforward novel, free tools are often enough. The guide to ebook formatting explains the standards your files need to meet.

ISBNs: the cost depends on your country

An ISBN is issued by the official ISBN agency in the country where the publisher is based, so you buy from your own country’s agency, not the cheapest one. Each format needs its own ISBN: the paperback, hardcover, ebook and audiobook are separate products. Whether you need one at all depends on where you sell; the guide ISBN explained: do you really need one? walks through that decision.

At the time of writing (October 2026), the official agencies list the following. Prices change, so check before buying.

Country	Agency	One ISBN	Block of ten	Notes
Canada	ISBN Canada (Library and Archives Canada)	Free	Free	For eligible publishers and publications
New Zealand	National Library of New Zealand	Free	Free	You will be asked to deposit copies once published
United States	Bowker (MyIdentifiers)	US$125	US$295	Larger blocks cost less per ISBN
United Kingdom	Nielsen ISBN Store	£93	£174	Prices include UK VAT
Australia	Thorpe-Bowker (MyIdentifiers Australia)	$44	$88	A one-off $55 setup fee applies to first-time buyers

Two free alternatives exist for many authors. KDP offers a free ISBN for paperbacks and hardcovers, but it can only be used with KDP. Draft2Digital assigns a free ISBN to books it distributes, which likewise cannot be used outside its services. Kindle ebooks on KDP do not need an ISBN at all. If you plan to publish in several formats through several companies, a block of ten from your national agency is usually better value than single ISBNs, and the publisher name on the record will be yours.

Proofs and author copies

Always order a printed proof before you publish a paperback or hardcover. Screens hide problems that are obvious on paper, such as tight margins, dark images and spine text that drifts.

On KDP, proof and author copies cost the printing cost for your book plus shipping and any taxes. The printing cost depends on trim size, ink type and page count. KDP’s own example for the US marketplace is a 300-page black-ink paperback in a regular trim size, which costs US$4.60 to print at the time of writing (October 2026). Colour interiors and larger trim sizes cost considerably more. Shipping, especially internationally, can cost more than the book itself, so budget for at least one proof per format and a second if you need to fix errors.

Marketing: decide your cap before you spend

Marketing has no natural upper limit, which is why it causes the most overspending. Some of the most effective methods cost little or nothing: an email list, a reader magnet, cross-promotion with other authors in your genre, and well-chosen keywords and categories. The guide to book marketing on a budget covers these.

Paid options include advertising platforms and paid promotion newsletters. If you try them:

• Set a total monthly cap and a daily budget before launching anything.
• Start with a small test and measure results before increasing spend.
• Advertise books that already have a strong cover, clear description and some reviews.
• Advertise the first book in a series, where read-through can recover the cost.

The guides to Amazon Ads for authors and whether a BookBub Featured Deal is worth it explain how to test these channels without losing money.

Audiobooks: optional, but often the largest single cost

Professional audiobook production is usually priced per finished hour, which means per hour of final audio, not per hour of studio time. ACX, Amazon’s audiobook production marketplace, estimates that about 9,300 words make one finished hour, so a 70,000-word novel would run to roughly seven and a half finished hours. That figure lets you turn any narrator’s per-finished-hour rate into a total.

The main ways to pay are:

• Pay per finished hour: you pay the narrator or producer a set rate when you approve the finished audio and keep all your royalties.
• Royalty share: you pay nothing upfront and split royalties with the narrator. On ACX this is only available with exclusive distribution, and ACX is not open to authors in every country.
• Digital narration: some retailers, including Apple Books, offer digitally narrated audiobooks, which cost far less than human narration but may not suit every genre or reader.
• Self-narration: the main cost is equipment, a quiet space and editing time.

The guide to audiobook production and distribution covers the process in more detail.

Three budget scenarios

Rather than inventing totals, these scenarios show which costs each level usually includes. Plug in your own quotes and the current figures above.

Item	Lean budget	Mid budget	Full professional budget
Developmental editing	Beta readers and critique partners	Manuscript assessment or one developmental pass	Full developmental edit
Copyediting and proofreading	Thorough self-editing plus a paid proofread if possible	Paid copyedit and proofread	Line edit, copyedit and separate proofread
Cover	DIY or premade	Premade or custom ebook cover with print wrap	Custom design or illustration
Formatting	Free platform tools	Formatting software	Professional formatter if the layout is complex
ISBNs	Free platform ISBN, or free national ISBN where available	Small block from your national agency	Block covering all planned formats and books
Proofs	One proof per print format	One or two proofs per format	Proofs plus author copies for events and reviewers
Marketing	Organic methods only	Small, capped advertising tests	Planned launch budget with tested channels
Audio	None yet	Digital narration or later release	Professional narration

Who each budget suits

• Lean suits authors testing a genre, publishing short non-fiction, or with strong editing skills or a trusted network of readers.
• Mid suits most first novels and serious non-fiction, where a paid copyedit and a professional-looking cover are what readers notice most.
• Full professional suits authors with a series plan, where the cost of each step can be spread across several books, or authors entering competitive genres with high reader expectations.

A budgeting checklist

1. Get your final word count, because most editing quotes depend on it.
2. Decide which editing passes you genuinely need, and request written quotes from at least two editors.
3. Decide your formats (ebook, paperback, hardcover, audio) before buying ISBNs.
4. Check your national ISBN agency’s current prices, or whether ISBNs are free where you live.
5. Choose your cover route and confirm the licence and print-ready files.
6. Budget for at least one printed proof per format, including shipping.
7. Set a total marketing cap and a monthly limit before launch.
8. Add a contingency for a second proof, extra edits or exchange-rate changes if you pay in a foreign currency.
9. Write down what each book needs to earn to cover its costs, so you can judge results honestly.

Common mistakes that waste money

• Paying for a proofread before the structure is settled. If you later rewrite chapters, you pay again.
• Buying single ISBNs one at a time when you know you will publish several formats or books.
• Buying an ISBN from a reseller in another country. ISBNs should come from the agency where the publisher is based.
• Skipping the printed proof to save on shipping, then discovering errors after readers have bought copies.
• Spending on adverts before the book is ready to convert, with a weak cover or description.
• Ignoring currency and tax. Many rate guides and platforms quote US dollars, and some prices exclude local taxes.

Avoiding scams and vanity presses

A legitimate self-publishing path means you hire individual professionals or use platforms that earn mainly from sales. Be cautious with any company that:

• Approaches you unsolicited, praising a book they have not read.
• Sells large packages that bundle editing, design, publishing and marketing for a single upfront price, without clear detail on each service.
• Charges for things the main platforms provide free, such as uploading to stores.
• Keeps your rights, files or a share of royalties after you have paid them.
• Promises bestseller status, film deals or guaranteed sales.
• Pressures you with deadlines or “limited places”.

Before signing anything, read the contract carefully, ask for itemised pricing, and check independent watchdog resources such as the Alliance of Independent Authors’ service ratings and Writer Beware.

Frequently asked questions

Can you self-publish a book for free?

Yes. KDP, Kobo Writing Life and similar platforms do not charge to upload a book, free formatting tools exist, and KDP provides a free ISBN for print books. You will still usually pay for at least one printed proof, and the quality of your editing and cover will depend on your own skills and time.

What is the most important thing to spend money on?

For most books, editing and the cover. Readers judge the cover before they click and judge the editing within the first pages of the sample. Formatting and ISBNs can often be handled cheaply or for free.

Do I need a separate ISBN for the ebook and the paperback?

Yes, each format is a separate product and needs its own ISBN if it uses one. Kindle ebooks on KDP do not require an ISBN, but other ebook retailers or distributors may assign or ask for one.

How much does it cost to self-publish a children’s book?

Usually more than a novel of similar length, because illustration is a major cost and colour printing costs more per page than black ink. Editing is cheaper because the text is short, but the illustrator’s fee and colour proofs tend to dominate the budget.

Is it cheaper to edit with software instead of an editor?

Grammar and style software can catch many mechanical errors and is useful before you hire anyone, because a cleaner manuscript makes an edit faster. It does not replace a human editor’s judgement on structure, voice and meaning, so many authors use both.

Do self-publishing platforms take a cut instead of charging fees?

Mostly, yes. Retailers keep a share of each sale, and distributors such as Draft2Digital take a commission. Draft2Digital also introduced a one-off US$20 activation fee for new accounts in 2026 and a US$12 annual maintenance fee for accounts earning under US$100 in net proceeds over 12 months.

A realistic budget starts with your word count, your formats and the country you publish from. Spend first on what readers see, test paid marketing in small steps, and keep a record of every cost so each future book gets easier to plan.
