Print-on-Demand Explained: How It Works and What It Costs

Print-on-demand (POD) is the printing model that makes physical book sales practical for indie authors. Instead of printing a batch of books upfront and warehousing them, print-on-demand means each copy is printed when a reader orders it. You carry no inventory; you pay no upfront printing cost; the printer handles fulfillment.

This model fundamentally changed what was possible for self-published authors. Before POD, self-publishing a print book required purchasing hundreds or thousands of copies upfront, at significant financial risk. With POD, a print edition costs nothing to publish, pays no warehouse fees, and remains available indefinitely.

This guide explains how POD works mechanically, what it costs, which providers serve indie authors, how royalties are calculated, and when to use which service.

How print-on-demand works

The process for a reader ordering your POD paperback:

1. A reader finds your book on Amazon (or another retailer), looks at the product page, and places an order
2. The order information reaches the print-on-demand provider (KDP Print, IngramSpark, etc.)
3. The provider prints a single copy of your book at their nearest fulfillment facility
4. The copy is bound and shipped directly to the reader, typically with the same delivery timeline as any Amazon product (2-day with Prime for KDP Print books)

You don't see the book until you order an author copy for yourself. The entire printing and shipping process happens between the provider and the reader.

What you provide: an interior file (print-ready PDF) and a cover file (full-wrap CMYK PDF). See our KDP cover specifications guide and KDP formatting checklist for the technical requirements.

What the provider does: prints, binds, and ships the book; handles payment collection and customer service on their platform; pays you your royalty per copy sold.

The major print-on-demand providers

KDP Print

KDP Print is Amazon's print-on-demand service, integrated directly into your Amazon KDP account. Setting up a paperback or hardcover on KDP Print happens in the same dashboard as your Kindle ebook.

Key features:

• No setup fee
• Books fulfilled by Amazon for Prime delivery on Amazon.com
• Available across Amazon's international marketplaces (Amazon UK, DE, FR, JP, etc.)
• Hardcover option (case-laminate binding)
• KDP authors can order author copies at printing cost (no royalty deduction on author copies)

Limitation: KDP Print books are primarily distributed through Amazon. The books appear in the Amazon Expanded Distribution program, which nominally makes them available to other retailers through Ingram, but the terms (wholesale discounts, returnability) are less favorable than direct IngramSpark setup for serious bookstore distribution.

IngramSpark

IngramSpark is the indie-author service from Ingram Content Group, the largest book distributor in the US. Setting up your book on IngramSpark puts it in Ingram's catalog, which is what most US bookstores and libraries order from.

Key features:

• True trade distribution: bookstores can order your book through their normal ordering systems
• Better wholesale discount options (you can set 55% discount, which is what most bookstores expect)
• Returnability option (whether you'll accept returns from retailers; many bookstores require returnability to stock books)
• Print quality comparable to traditional publishers (IngramSpark uses the same distribution networks)
• Global distribution to international markets and libraries

Cost: IngramSpark charges a setup fee per title (typically $49 for print, though this is sometimes waived through ISBN purchases or promotional periods). Revision uploads also have a fee. This is a meaningful cost difference from KDP Print's free setup.

Requires an ISBN: IngramSpark requires an ISBN for all titles. You can use an IngramSpark-assigned free ISBN (they're listed as publisher) or your own.

Draft2Digital Print

Draft2Digital is primarily an ebook aggregator, but it also offers a print service. D2D Print distributes through Ingram, making it an alternative to direct IngramSpark setup.

Key features:

• Free to set up (no title fees)
• Integrated with D2D's ebook distribution if you're already using D2D for ebooks
• Less direct control over IngramSpark metadata than using IngramSpark directly

Consideration: D2D's print service is convenient if you're already using D2D for ebooks and want print distribution without the IngramSpark setup fee, but direct IngramSpark setup gives more control.

Lulu

Lulu is a long-established POD provider used by some indie authors, particularly for special formats (large format books, hardcovers with dust jackets, spiral binding) that other services don't offer. Lulu also has a direct-to-reader storefront.

Common use cases: illustrated books, workbooks, journals, children's books, and other format needs that KDP Print and IngramSpark don't support as well.

Print-on-demand royalty calculation

The royalty model for POD is different from ebook royalties. You earn the list price minus the printing cost minus the retailer's cut.

KDP Print royalty formula

For paperbacks on Amazon:

Royalty = (List price × 0.60) minus Printing cost

KDP pays 60% of the list price as the gross royalty amount, then deducts the printing cost (which varies by page count, trim size, and paper type) from that amount. Your net royalty is what remains.

Example: a 300-page 6×9 paperback on white paper has an approximate printing cost of $4.45.

• List price: $14.99
• Gross royalty: $14.99 × 0.60 = $8.99
• Printing cost: $4.45
• Net royalty: $8.99 - $4.45 = $4.54

For expanded distribution (through KDP's distribution to non-Amazon retailers), the royalty is 40% of the list price minus the printing cost, resulting in a significantly lower per-copy royalty.

Printing costs vary; KDP's royalty calculator at the book setup stage gives you exact costs for your page count and trim size.

IngramSpark royalty formula

IngramSpark's royalty structure is:

Net royalty = List price minus (printing cost + wholesale discount)

You set the list price and the wholesale discount percentage. The wholesale discount is the discount you offer to retailers (bookstores, libraries) who order through Ingram. Common settings:

• 55% discount: what most bookstores expect for stocking books. At 55% off a $15.99 book, the retailer pays $7.20, and your royalty is $7.20 minus the printing cost.
• 40% discount: common for Amazon marketplace sales through Ingram; some other online retailers.
• 30% discount: minimum that most retailers will order at; not suitable for bookstore stocking.

For a 300-page paperback with $4.50 printing cost, $15.99 list price, and 55% discount:

• Retailer pays: $15.99 × (1 - 0.55) = $7.20
• Printing cost: $4.50
• Net royalty: $7.20 - $4.50 = $2.70

The per-copy royalty at high discount rates is significantly lower than on Amazon direct, but IngramSpark distribution reaches bookstores that don't exist through Amazon.

Pricing your POD book

Your list price must be high enough to generate a positive net royalty after printing costs and retailer discounts. This creates a practical minimum price floor for print books.

Useful guideline: for any given print book, use KDP's royalty calculator to find the minimum price that gives you a positive royalty on Amazon, then consider whether IngramSpark's higher discount would make the price unviable.

Common price ranges for trade paperbacks:

• 200-page book: typically $10.99-$13.99
• 300-page book: typically $13.99-$17.99
• 400-page book: typically $16.99-$21.99

Readers have genre expectations about print book prices. A 300-page romance paperback priced at $25 will underperform compared to the same book priced at $15.99, because it exceeds what readers expect to pay for the format in that genre.

Using KDP Print and IngramSpark together

Most indie authors who want both Amazon sales and bookstore distribution use both services for print:

• KDP Print for the Amazon product page (best royalties on Amazon, Prime fulfillment for Amazon customers)
• IngramSpark for bookstore and library distribution (where being in Ingram's catalog matters)

The complication: if both KDP and IngramSpark are fulfilling Amazon orders, they can compete on the Amazon listing. The most common approach is to disable KDP's Expanded Distribution and let IngramSpark handle non-Amazon distribution, while KDP handles Amazon specifically.

This requires careful setup and pricing to avoid Amazon listing issues; consult current guidance in indie author communities before implementing both services simultaneously.

Ordering author copies and proofs

POD services allow authors to order copies of their own books at printing cost, without paying the royalty markup. This is an important part of the publishing workflow:

Proof copy before approving: order one copy of your book before enabling it for sale or confirming it for distribution. Hold it, read it, check the spine, feel the paper. Problems with interior layout, cover color rendering, or binding quality are much easier to address before the book goes live than after.

Author copies for events: for speaking engagements, book signings, or local events, ordering author copies directly and selling them yourself at list price lets you keep the full margin rather than the royalty from retailer sales.

Gifting and ARC copies (print): if you're offering print ARCs to reviewers, ordering author copies at cost and shipping them yourself is the most economical route (rather than gifting via a retailer gift link, which charges list price).

What to check in your proof copy:

• Cover colors (CMYK print can look different from your screen preview; check for unexpected color shifts)
• Spine width accuracy (is the text centered on the spine?)
• Interior margins (is text clear of the gutter on both left and right pages?)
• Chapter header layout and drop cap design
• Image quality and any grayscale conversion for color images
• Page numbers (do they appear on the right pages, absent from chapter openers and blank pages?)
• Overall "feel" of the book in hand

Upload corrected files before approving for sale if any issue is significant enough to affect reader experience.

Color vs. black-and-white print

Most text-focused books (fiction, narrative nonfiction) use black-and-white interiors, which is less expensive to print and results in better per-copy royalties.

Color interiors are necessary for:

• Children's picture books and illustrated books
• Cookbooks with food photography
• Art books
• Travel guides with significant photography
• Technical books with colored diagrams where color is essential to the content

Color printing costs significantly more; the price per page for color printing is roughly 5-7× higher than black-and-white. This requires a higher list price to maintain a viable royalty, which can limit competitiveness in the market.

For books with some color elements that aren't essential (decorative header images, subtle illustrations), using grayscale versions of these elements in the print interior while maintaining a color ebook cover is often the better economic choice.

International POD printing facilities

KDP Print and IngramSpark operate printing facilities in multiple countries, which reduces shipping time and cost for international orders. When a reader in the UK orders your book from Amazon UK, it's typically printed at a UK facility rather than shipped from the US.

This matters for author pricing decisions: if you set your UK list price in GBP, ensure the price is appropriate for the local market (not just a direct exchange-rate conversion, which may result in a price that feels off to UK readers) and that the UK printing cost still leaves a positive royalty.

IngramSpark's international distribution similarly routes through printing and distribution facilities in relevant markets for international orders.

When print-on-demand doesn't make sense

Print-on-demand is not the right tool for every situation:

High-volume bulk sales: if you're selling your book directly from your own website, at speaking engagements, or in bulk to organizations, purchasing a short print run from an offset printer or POD in bulk (at lower per- unit cost) may be more economical than per-copy POD pricing.

Specific quality requirements: POD print quality is good to excellent but is not identical to offset-printed books in every respect. For extremely photography-heavy or color-critical interior content, testing POD output against your expectations is important before committing.

Very short books: books under 100 pages sometimes fall below minimum page count requirements for some POD providers and produce spines too thin for text.

Print-on-demand for special formats

Beyond standard paperbacks and case-laminate hardcovers, some POD providers offer specialty formats:

Dust jacket hardcovers: IngramSpark offers hardcovers with printed dust jackets, which look more like traditionally published hardcovers than KDP's laminate case-bound option. This appeals to literary fiction authors and nonfiction authors in categories where readers expect hardcover quality.

Large print: printing a separate large-print edition (larger trim size, 14-16pt body text) expands your book's accessibility. Large-print editions require their own ISBN and POD setup, and typically their own formatted file. The large-print market (readers with visual impairments, older readers) can be meaningful for nonfiction and certain fiction genres.

Spiral-bound: some POD providers (Lulu in particular) offer spiral-bound books. These are most appropriate for workbooks, recipe collections, and other books readers interact with actively rather than just reading straight through.

Square trim sizes: children's books, art books, and gift books often use square trim sizes that differ from standard fiction and nonfiction formats. IngramSpark and Lulu support several square trim sizes; KDP Print does not support square formats.

Managing POD files long-term

Your POD interior and cover files represent an investment of time and money. Managing them well reduces work when you update the book in the future.

Keep the following organized and backed up:

• Source project files (your LiberScript project, or your Word/InDesign source document)
• Final exported interior PDF (labeled with the version number and date)
• Final cover files (the working file and the final exported print-ready PDF)
• Your style sheet (character name spellings, world-specific terminology, formatting decisions)

When you update a book (correcting errors, adding new back matter, releasing a new edition), you'll need to re-export from your source file, not try to edit the existing PDF directly. Having clean, well-labeled source files makes this straightforward.

Frequently asked questions

How long does it take for a POD book to be printed and shipped?

For KDP Print books sold on Amazon, printing and shipping is integrated with Amazon's fulfillment system. Prime-eligible books typically arrive in 2 days for US customers. International shipping varies by marketplace.

Can I sell my POD book in a physical bookstore?

With IngramSpark distribution, your book can be ordered by bookstores. Whether a bookstore actually stocks it is their decision, influenced by your discount terms, returnability settings, and the store's buying priorities. IngramSpark distribution makes your book orderable; it doesn't guarantee shelf placement.

What's the minimum print run for POD?

One copy. That's the entire point of print-on-demand. Each order triggers one print job.

How does POD affect my ISBN?

If you're using KDP Print only, Amazon handles its own barcode and ASIN without requiring you to provide an ISBN. If you're publishing through IngramSpark, an ISBN is required. See our ISBN guide for full details.

The bottom line

Print-on-demand removes the financial risk from publishing a physical book. You invest in the manuscript, cover design, and formatting; the printer provides books one at a time, paid for by the reader who ordered them.

KDP Print is the simplest starting point for Amazon print sales. IngramSpark is the route to bookstore and library access. Most authors with ambitious distribution goals use both. Format your interior correctly before uploading, and use your real final page count to design the cover spine.
