Self-Publishing

How Much Does It Cost to Self-Publish a Book?

By the Inkora team · Nov 2, 2026 · 10 min read

You can self-publish a book for nothing but your time. Amazon KDP and Draft2Digital charge no upload or listing fees, and both can give you a free identifier or ISBN. Everything else is optional: editing, cover design, formatting, your own ISBNs, proof copies and marketing. What you spend depends on which of those you hire out, which you do yourself, and how polished you need the result to be.

This guide goes through each cost in turn. For each one it covers what you can get free, when paying makes sense, and what pushes the price up or down. It doesn't list price figures, because rates vary by country, genre, provider and year. Get two or three quotes for anything you plan to hire out.

If you haven't mapped out the whole process yet, start with how to self-publish a book and come back here to budget it.

The cost of self-publishing on KDP or Draft2Digital

The publishing step itself is free on both platforms. Neither charges a setup fee, a listing fee or an annual fee. Each one makes money by taking a share of your sales.

  • Amazon KDP (ebook): No ISBN needed. Amazon assigns a free ASIN. Royalty under KDP's published terms is 70% for list prices from $2.99 to $9.99, minus a delivery fee, and 35% outside that range.
  • Amazon KDP (paperback): An ISBN is required. KDP offers one free, but it can only be used on KDP. Your royalty is a percentage of list price minus the printing cost. KDP's published terms put it at 60% on Amazon (50% for books under $9.99 on Amazon.com), and 40% through Expanded Distribution.
  • Draft2Digital: The ISBN is optional, and D2D can assign one free. D2D sends your ebook to many stores and keeps a fee of roughly 10% of list price from each sale.

These rates change from time to time, so check the current terms in each dashboard before you set a price. The KDP royalty calculator shows what a given list price and page count would earn you.

The real costs are the services that sit around the upload.

The cost of editing a book

For most authors, editing is the largest optional expense. It's also where spending tends to pay off most, because readers notice errors and loose structure fast.

There are four main kinds of edit, and they are priced very differently:

  • Developmental edit: big-picture structure, pacing, plot or argument. Usually the most expensive per word because it takes the most judgment. See developmental edit.
  • Line edit: sentence-level style, clarity and flow.
  • Copyedit: grammar, consistency, usage, house style.
  • Proofread: a final check for typos and formatting slips. Usually the cheapest pass.

What drives the price:

  • Word count. Editors often quote per word, per page or per hour, so a longer manuscript costs more.
  • The state of the draft. A messy draft takes longer to edit, and some editors adjust their quote after a sample.
  • Genre and subject. Technical non-fiction, academic material and heavily researched work can cost more.
  • Turnaround. Rush jobs usually cost extra.
  • Experience and specialism. Editors with a track record in your genre often charge more.

The free route: Self-edit in several passes, read the text aloud, use beta readers, and use free grammar tools for surface errors. How to edit your own book walks through a workable process.

Where money matters most: If you can afford only one paid edit, many authors choose a copyedit or a careful proofread, because those errors are the most visible to readers. A developmental edit is worth considering for a first novel, or for any book that beta readers say isn't working.

The cost of a book cover

A cover can cost nothing or a significant sum. It depends on three things: how custom it is, whether you need print, and who makes it.

Cost factors:

  • Ebook only or full wrap. An ebook needs only a front image. KDP's published spec is a JPEG or TIFF, ideally 1600 × 2560 px. A paperback needs a full-wrap PDF with back, spine and front plus 0.125" bleed on every edge, which takes more work.
  • Premade, custom or illustrated. Premade covers are usually the cheapest paid option. Fully custom designs cost more. Commissioned illustration, common in fantasy and children's books, usually costs the most.
  • Image licensing. Stock photos and fonts may need a commercial licence. Check the terms for each asset you use.
  • Revisions and extra formats. Additional rounds, audiobook squares and social graphics can add to a quote.

Doing it yourself: Typographic covers built from clean type and a simple layout can look professional in genres like non-fiction and literary fiction. KDP's Cover Creator is free. Inkora's cover designer has typographic templates, optional AI cover artwork, and exports both a 1600 × 2560 Kindle JPG and a full-wrap PDF with the spine width calculated from your page count.

Where money matters most: Genre fiction readers judge fast, and a cover that looks wrong for its genre can hurt sales. If you write romance, thrillers or fantasy, a cover that clearly matches what's selling in your category is often worth paying for.

The cost of formatting a book

Formatting, also called interior layout or typesetting, turns your manuscript into an EPUB for ebook stores and an interior PDF for print.

What affects the cost:

  • Complexity. A novel with plain chapters is simple to lay out. Cookbooks, textbooks, picture books and anything with tables, images or footnotes take much longer.
  • Number of formats. Ebook plus paperback plus hardcover means more files to build and check.
  • Trim size changes. If you change trim size after layout, the interior usually has to be redone.

Free options: KDP's Kindle Create tool is free. Draft2Digital also formats ebooks and print interiors free as part of its service. Inkora exports an EPUB 3, DOCX and a print-ready interior PDF at eight trim sizes from the book you write there, and its credits are pay-as-you-go. Current details are on the pricing page.

The paid route: You can hire a formatter or buy formatting software. Software makes the most sense if you plan several books, because you pay once and reuse it.

When you need to buy an ISBN

Not always. Whether you need one depends on the format and on where you sell. For background, see ISBN.

Where you publish Ebook ISBN Print ISBN Free option?
Amazon KDP Not required (ASIN assigned) Required Yes, free KDP ISBN for paperbacks, usable on KDP only
Draft2Digital Optional Optional Yes, D2D can assign one free
Apple Books Not required n/a Not needed for ebooks
Google Play Books Not required (GGKEY assigned) n/a Not needed for ebooks
Kobo Writing Life Not required n/a Not needed for ebooks
Barnes & Noble Press Not required for ebooks Required Check B&N Press for current options
IngramSpark Required for each format Required for each format No, you must supply your own
Lulu Optional for printing copies Optional for printing copies Not needed for private copies

When buying makes sense:

  • You want the same print ISBN everywhere. A free KDP ISBN can't be used at IngramSpark or anywhere else.
  • You want your own imprint name listed as publisher. Free store ISBNs list the store or a generic name instead.
  • You publish several formats or books. Each format (ebook, paperback, hardcover) needs its own ISBN.

Pricing: ISBNs are sold by the national ISBN agency in your country, and pricing differs a lot from country to country. Some countries issue them free to local publishers. Where they're sold, a block of ISBNs usually costs less per number than a single one. Check your national agency's current price list before you buy.

The cost of proof copies and author copies

A proof copy is a printed test of your book. Ordering one before you publish lets you catch problems with margins, cover alignment, colour and paper that don't show up on screen.

What sets the cost:

  • Printing cost. This depends on page count, trim size, paper type and whether the interior is black-and-white or colour. Colour interiors cost noticeably more to print.
  • Shipping. Shipping cost and speed vary by country and method, and international delivery can take a while.
  • Number of rounds. Each fix you make and re-check means another proof order.

On KDP, proofs and author copies are charged at the printing cost plus shipping and tax. Check the current figures in your KDP account for your trim size and page count.

Proofs are technically optional, but skipping them is a common false economy for print books. Inkora's Publishing Hub includes Lulu print orders for proofs and author copies. With Lulu, you pay Lulu's print and shipping cost for each order.

How much to spend on marketing

Marketing has no fixed cost. You can spend nothing, or you can spend more on it than on everything else combined. Most authors start small and spend more only on what works.

Free or nearly free:

  • A strong blurb, accurate keywords and well-chosen categories. These cost nothing and affect how readers find and judge your book.
  • An author newsletter. Many email services have free tiers for small lists.
  • Advance reader copies (ARCs) sent to readers who may leave honest reviews.
  • Social posts, guest posts, podcasts and local events.
  • Price promotions through store tools such as KDP Select deals, if you're enrolled.

Paid options:

  • Store ads (Amazon, for example). You set the budget, and costs depend on your bids and competition in your category.
  • Promotion and newsletter-feature sites. These charge per placement, and the price usually depends on genre and audience size.
  • ARC distribution services. These charge to put your book in front of reviewers.

Spending depends on: Your genre's competitiveness, how many books you have (a series can earn back ad spend more easily than one standalone book), and how long you run campaigns.

A practical approach is to set a test budget you can afford to lose. Run one channel at a time, and track sales against spend before you increase anything.

Other costs to budget for

A few smaller items catch people out:

  • Copyright registration. Your work is protected by copyright as soon as you create it. Formal registration is optional and the fees vary by country.
  • Tax and business setup. Stores require tax information. You may also want an accountant, a business registration or a separate bank account, depending on where you live.
  • Software and writing tools. This includes word processors, grammar tools, formatting software and AI writing credits.
  • Website and domain. These are optional, since a free author page on the stores or a newsletter landing page may be enough to start.
  • Audiobook production. This is a separate project, with costs driven by narrator, length and production quality.

Common problems and fixes

You took the free KDP ISBN and now want to sell in print through IngramSpark. The KDP ISBN can't be reused there. Get your own ISBN for the IngramSpark edition. If you want one ISBN across all retailers in future, buy your own before your next print release.

Your cover designer delivered a full wrap with the wrong spine width. Spine width depends on the final page count and paper type. Finalise the interior first, then give the designer the exact page count, or have them use the store's own cover template. IngramSpark's spine width and barcode position can differ from KDP's.

Your first proof arrives with text too close to the spine. Increase the inside (gutter) margin, re-export the interior, and order another proof. Budget for at least two proof rounds on any print book.

An editing quote is far beyond your budget. Do a thorough self-edit and a round with beta readers first, because a cleaner draft can lower the quote. Then hire for the single pass you need most, usually a copyedit or proofread.

You're spending on ads with few sales to show for it. Pause the ads. Look at your cover, blurb, price and first pages against bestsellers in your category, since ads can't fix a page that doesn't convert. Then restart with a smaller budget.

You bought one ISBN and now need more. Each format and each new book needs its own number. Next time, compare the per-number cost of a block against buying singles.

You underestimated colour printing. Colour interiors raise the printing cost, which cuts your royalty per copy on print-on-demand. Check printing cost and royalty before you set a list price. You may need a higher price, a black-and-white interior, or an ebook-first release.

Self-publishing has no required price. The platforms are free, and every other cost is a choice you make based on your book and your budget. Spend where readers will notice, which usually means a clean edit and a cover that fits your genre. Do the rest yourself, and grow your marketing budget only once you can see what's working.

Frequently asked questions

Is it cheaper to self-publish an ebook only, without a paperback?+

Usually, yes. An ebook-only release skips the full-wrap cover, the print layout, the print ISBN and proof copies, so you can add a paperback later if the ebook sells.

Can I pay my editor or cover designer out of royalties instead of upfront?+

Some freelancers offer payment plans, but most expect payment before or during the work. Royalty-share deals are uncommon, so ask directly and get any arrangement in writing.

Does using a free KDP ISBN make my book look less professional?+

Most readers never check ISBN details. The main visible difference is that the publisher field shows a generic name instead of your own imprint, which matters more for bookstore or library sales.

Are vanity or "full-service" publishing packages worth the money?+

Be cautious. Many bundle services you can do free on KDP or Draft2Digital and may take rights or royalties as well, so read the contract and compare each line item against doing it yourself.

Do I have to pay to change my book after it's published?+

Updating files on KDP and Draft2Digital is free. A changed print interior or cover may mean ordering a new proof, and a new edition with substantial changes may need a new ISBN under your agency's rules.

Can I deduct self-publishing costs from my taxes?+

In many countries, writing and publishing expenses can count as business costs, but the rules vary widely. Keep receipts and check with a local tax adviser.
