Costs
How much does it cost to self-publish a book?
A professionally produced self-published book typically costs $2,800–$5,300 in total, including editing and cover design, according to Reedsy's cost guide. Budget DIY routes run $500–$1,500, while premium routes with a print run and marketing reach $5,000–$15,000 or more, per books.by.

How much does book editing cost?
Editing is usually the largest single expense. The Editorial Freelancers Association's 2026 rate chart gives fiction copyediting at 2.0–2.7¢ per word and fiction proofreading at 1.2–2.0¢ per word. For an 80,000-word novel that is roughly $1,600–$2,160 for a copyedit and $960–$1,600 for a proofread (our arithmetic).

How much does a professional book cover cost?
The average professional custom book cover costs about $880, with most projects between $625 and $1,250, according to Reedsy's analysis of 9,600 cover collaborations. Pre-made covers run roughly $40–$150, while fantasy and science-fiction covers tend to cost more, averaging above $1,500.

How much does it cost to print a paperback book?
Print-on-demand unit cost depends on page count and ink. Amazon KDP charges a $1.00 fixed cost plus $0.012 per page for black-and-white paperbacks, so a 200-page book costs about $3.40 to print (our arithmetic from KDP's own worked example). Full-colour interiors cost considerably more per copy.

How much does it cost to illustrate a children's book?
Freelance illustration for a 24-page children's book costs $1,540–$4,950, per Reedsy data. Children's books also need specialist interior layout, which adds cost beyond a standard text-only book. Illustration and full-colour interiors are the main reasons children's books cost more than novels to produce.

How much does it cost to self-publish a children's book?
Expect the standard self-publishing range of $2,800–$5,300 (Reedsy), plus illustration of roughly $1,540–$4,950 for a 24-page picture book, and a colour interior that prints far more expensively than black-and-white. Budget children's books at the top of the scale, often $5,000 or more.

Does self-publishing cost anything on Amazon KDP?
No. Publishing on Amazon KDP is free to upload and distribute: KDP charges nothing upfront and deducts printing costs from each print sale. The real spend is on editing, cover design and formatting, where authors typically invest $500–$1,000 at a minimum for a commercially competitive book.

Timelines
How long does it take to self-publish a book?
Most authors self-publish in 3–8 months; Reedsy puts a realistic figure at 3–6 months, or 5–8 with complex interior design. The mechanical upload can clear in about 3 days, but editing, design and formatting dominate the timeline. Traditional publishing, by contrast, averages 2–4 years.

How long does professional editing take?
Full professional editing runs 6–12 weeks for most manuscripts, per The Paper House Books. On the Reedsy marketplace the average editor turnaround is 57 days, about two months. A focused copy edit and proofread is faster, while developmental editing of a long book takes longer.

How long does cover design take?
A professional cover designer needs 1–2 weeks for initial concepts plus 3–5 business days per revision round, per Publishing Xpress. On Reedsy the average designer turnaround is 66 days. Running cover design in parallel with editing can save 2–4 weeks on the overall schedule.

How long does book formatting take?
A professional formatter needs 5–10 business days for a 200-page trade paperback, per Publishing Xpress. DIY formatting in InDesign or Affinity Publisher takes 2–3 weeks including revisions. Children's books and image-heavy interiors take longer and may need a specialist layout designer.

How long does book printing take?
Standard short-run perfect-bound printing takes 7–10 business days after file approval. Runs under 100 copies often use digital printing at 5–7 business days, while runs above 500 may go offset, which takes 15–20 business days. Rush production costs 20–40% more.
Source: publishingxpress.com, "How to Create a Book Publishing Schedule"
How long does it take to publish a children's book?
Add illustration time to the standard timeline: a 24-page picture book needs a cover plus interior illustration, and Reedsy notes children's books often need specialist layout adding up to 2 months. A realistic total is 4–8 months from a finished manuscript if illustration starts early.

How long does Amazon KDP take to approve a book?
KDP usually reviews a submitted file in about 3 days; Reedsy notes you could publish in roughly that time if the manuscript were ready. KDP's own review window is commonly quoted as 24–72 hours, though the approval time varies, and paperback files are typically approved faster than first-time ebook submissions.

How long does traditional publishing take?
Traditional publishing averages 2–4 years from query to bookshelf. Querying takes 3–12 months, agent submission 3–18 months, and publisher production 12–24 months. Greenleaf Book Group reports 18 months from signed contract to shelves, even after a deal has been agreed.

ISBNs
Who issues ISBNs in the UK?
Nielsen (nielsenisbnstore.com) is the UK and Ireland ISBN agency, and its metadata feeds Nielsen BookData, which British bookshops use. You must be based in the UK, Ireland or a British Overseas Territory to buy from it. Check the Nielsen store for current prices, as they change.

Who issues ISBNs in Nigeria?
The National Library of Nigeria (NLN) issues ISBNs, through its online portal at isbn.nln.gov.ng, where authors create a profile and then apply. NLN also runs a Nigerian ISBN Registry for checking genuine Nigerian ISBNs. Fees and processing times are set by NLN, so check the portal before you apply.

Are ISBNs free in Canada?
Yes. Library and Archives Canada issues ISBNs free of charge to Canadian publishers, who must provide proof of Canadian residency. Canada is one of several countries, with New Zealand, France and India, where ISBNs are government-administered and free, unlike the private agencies in the US and UK.

Who issues ISBNs in Australia?
Thorpe-Bowker is Australia's ISBN agency, run through MyIdentifiers.com.au. Australian pricing is much lower than in the US, and Thorpe-Bowker also sells barcodes and ISBN-plus-barcode bundles. Check MyIdentifiers.com.au for current prices before you buy, as agency prices change from time to time.

Do I need an ISBN to publish a book?
An ISBN is not a legal requirement, but it is what publishers, booksellers and libraries use to order, list and track a book. To sell into bookstores and libraries you need one. For ebooks and digital audiobooks it is optional, though self-publishing bodies such as ALLi recommend owning one.
Source: Nielsen ISBN Store; Alliance of Independent Authors (selfpublishingadvice.org)
Do I need a separate ISBN for each format?
Yes. The rule is one ISBN per format, per edition, so a title released as paperback, hardcover, EPUB and audiobook needs four separate ISBNs. A revised edition with substantial content changes needs a new ISBN; a reprint with no content change does not.
Source: originbooks.com ISBN guide; ourcodeworld.com 2026 guide
Can I use one ISBN for paperback and ebook?
No. Paperback and ebook are different formats, and each requires its own ISBN. A title published as both needs at least two ISBNs. Buying a block of ISBNs from your national agency is usually better value than buying single numbers one at a time, so compare the agency's block price.

Printing, royalties and distribution
What is the difference between print-on-demand and offset printing?
Print-on-demand (POD) prints books one at a time, only when ordered, so there is no upfront inventory but the per-copy price stays flat. Offset printing runs a bulk order, typically 500–1,000 or more copies, at a much lower per-unit price, but needs upfront spend and storage. POD suits most self-publishers.

What does Amazon KDP pay in royalties?
KDP pays 70% of list price on ebooks priced $2.99–$12.99 and 35% outside that range. For paperbacks it pays 60% of list price minus printing cost at $9.99 and above and 50% below that, and 40% of list price minus printing cost through Expanded Distribution.

What does IngramSpark offer that KDP does not?
IngramSpark distributes to over 45,000 bookstores, retailers and libraries, according to its own distribution page, which makes it the route to physical bookstore and library presence. Authors set a wholesale discount, commonly 40–55%, and earn list price minus print cost minus that discount. It includes no editing, design or marketing.

Who keeps the rights and royalties in self-publishing?
In self-publishing the author keeps 100% of the rights and typically earns 35–70% royalties, versus 10–15% on print and 25% on ebooks in traditional publishing, where the publisher acquires rights. Self-published authors earn no advance; all income is per-copy royalty paid by the platform.
Source: freyjapublishing.com; editorworld.com; books.by
Is an ebook or a print book cheaper to publish?
An ebook is cheaper to publish: there are no printing or distribution production costs, only editing, cover and formatting. Amazon KDP pays 70% on ebooks priced $2.99–$12.99. Print books carry a per-copy printing cost that is deducted before royalty, so the unit margin is lower.

What does a self-publishing company actually do?
A supported self-publishing company bundles the services an author would otherwise coordinate: editing, cover and interior design, print and ebook formatting, ISBN assignment, upload to retail platforms, and distribution setup. The author retains rights and royalties while the company handles production. DIY and traditional publishing are the other main paths.

How much does distribution cost the author?
On Amazon KDP, Expanded Distribution pays 40% of list price minus printing cost, compared with 60% on Amazon itself, and it does not guarantee that booksellers will order your book. On IngramSpark, earnings are reduced by the wholesale discount you set, typically 40–55%. Retailer margins cut into royalty.

Choosing a route
Is self-publishing worth it?
For most first-time authors, yes: you keep a much larger royalty share (35–70% versus 10–15%) and publish in months rather than years. The trade-off is that all production and marketing work, and its cost, falls on you. Self-publishing suits authors who can invest upfront in editing and design.
Source: printingcenterusa.com; editorworld.com
Can I publish a book for free?
Yes. Amazon KDP charges nothing to upload or distribute, so a book can go live for free. But "free" means DIY editing and a DIY cover, which tends to produce a book that struggles commercially. A realistic minimum spend for a competitive book is $500–$1,000 on editing and cover design.
Source: selfpublishing.com; authorsolutions.com
Do I need a literary agent to publish a book?
Only for traditional publishing with a major or mid-size house, which acquire almost exclusively through agents, whose acceptance rate is roughly 1–2% of submissions. Self-publishing, hybrid publishing and many small presses require no agent; the author publishes directly through retail platforms.
Source: editorworld.com; books.by
What is the best self-publishing company or platform?
There is no single best platform; the choice depends on your goal. Amazon KDP dominates retail reach (over 50% of ebook sales, per freyjapublishing.com) at a 70% ebook royalty, while IngramSpark is the choice for bookstore and library distribution through over 45,000 outlets. Many authors use both.

How do self-published authors get into bookstores?
Through wholesale distribution: bookstores buy via wholesalers and expect a 40–55% discount plus returnability, which platforms like IngramSpark provide, making a title technically orderable. Being orderable is not the same as being stocked; physical shelving usually needs direct pitches to local independent bookstores.
Source: printingcenterusa.com; litreactor.com
How long does it take to write a book before publishing?
Most authors take 6 months to a year for a complete first draft, per Reedsy survey data, with an average of around 180 days. Planning and outlining take 1–4 weeks, drafting 2–9 months, and editing and revision add 1–3 months. Publishing time is separate.
