How KDP Print-on-Demand Works

Kindle Direct Publishing (KDP) uses a print-on-demand model, which means no copies of your book are printed or warehoused in advance. Instead, when a customer places an order on Amazon, the book is printed at the nearest fulfillment center and shipped directly to them. Amazon deducts the printing cost from your list price before paying your royalty.

This model eliminates the financial risk of traditional publishing runs. You do not pay for inventory upfront, and you do not lose money on unsold stock. However, the printing cost does directly reduce what you earn per sale, which makes understanding that cost critical to pricing your book correctly.

KDP currently supports print books on 14 Amazon marketplaces across North America, Europe, Asia, and Australia. Each marketplace has its own printing cost structure, royalty threshold, and currency. A book that earns well on Amazon.com may earn proportionally more or less on Amazon.co.uk or Amazon.de, even after accounting for currency exchange.

The Printing Cost Formula

KDP uses a two-part formula to calculate the printing cost of any print book. There is a fixed base cost and, for books above a certain page count, a per-page cost that scales with the length of the book.

The fixed base cost covers the expense of binding, cover printing, and setup, while the per-page rate reflects the cost of the paper and interior ink. The specific values for each component depend on:

• The book format (paperback or hardcover)
• The ink type (black and white, standard color, or premium color)
• The trim size (regular or large)
• The paper type (white, cream, or groundwood)
• The marketplace where the book is sold

For short books, KDP applies only the fixed base cost. Once a book exceeds a certain page threshold – 108 pages for most black and white paperbacks – the per-page rate is also applied. This means printing cost grows roughly linearly with page count beyond that threshold.

Printing Costs by Ink Type

KDP offers three interior ink options for paperbacks, and two for hardcovers. Your choice significantly affects the printing cost and therefore the minimum viable list price for your book.

Black and White (B&W)

Black and white is the lowest-cost option and is appropriate for novels, memoirs, non-fiction, poetry, and any book that does not rely on color images. On Amazon.com, a B&W paperback with a regular trim pays a flat rate of $2.30 for books up to 108 pages. For books with 110 pages or more, the cost is $1.00 + (page count x $0.012). A 300-page B&W paperback, for example, costs $4.60 to print on Amazon.com.

Standard Color

Standard color uses a single ink pass and is suitable for books with color charts, diagrams, or images where photographic quality is not required. It is available on Amazon.com, Amazon.co.uk, Amazon.de and other European stores, Amazon.ca, Amazon.pl, and Amazon.se – but not on Amazon.co.jp or Amazon.com.au. Standard color requires a minimum of 72 pages and a maximum of 600 pages. On Amazon.com, the cost is $1.00 + (page count x $0.0255), making it approximately 2.1 times more expensive per page than black and white.

Premium Color

Premium color produces photographic-quality color reproduction and is suited to children’s books, photography books, cookbooks with full-color photos, and art books. It is available on all KDP marketplaces and supports paperbacks from 24 to 828 pages. On Amazon.com, books of 40 pages or fewer pay a flat rate of $3.60; books with 42 or more pages pay $1.00 + (page count x $0.065). This makes premium color significantly more expensive – a 300-page premium color paperback costs $20.50 to print, compared to $4.60 for the same book in B&W.

Hardcover books are only available in black and white or premium color, with no standard color option.

How Paper Type Affects Your Printing Cost

KDP offers three interior paper options: white paper, cream paper, and groundwood paper (currently in beta). Choosing the right paper is partly an aesthetic decision – cream paper is popular for fiction because it is easier on the eyes – but paper type also has a direct effect on printing cost.

White Paper

White paper is the standard option and is available for all ink types and all KDP-supported formats. It produces sharp contrast with black text and is the default for non-fiction, textbooks, workbooks, and color books.

Cream Paper

Cream paper has a slightly warmer tone and is available for black and white interior books only. It is a common choice for fiction, where readers appreciate its resemblance to traditional printed novels. The printing cost for cream paper is identical to white paper on all marketplaces.

Groundwood Paper (Beta)

Groundwood paper is a recycled-fiber paper currently available through KDP as a beta feature. It is available for black and white interiors only, and its availability varies by marketplace. Groundwood paper has a slightly more textured, off-white appearance similar to newspapers or mass-market paperbacks.

From a cost perspective, groundwood paper carries a 5% reduction in printing cost compared to white or cream paper. On a 300-page black and white paperback on Amazon.com, this brings the printing cost from $4.60 down to $4.37 – a saving of $0.23 per copy sold. While modest on a per-copy basis, this adds up across higher sales volumes and helps reduce the minimum viable list price slightly.

Trim Sizes and Their Impact on Cost

The trim size of your book – its physical width and height – directly affects the per-page printing rate. KDP divides trim sizes into two tiers.

Regular Trim Sizes

Regular trim sizes are any dimensions up to and including 6.12 inches wide by 9 inches tall. These carry lower per-page printing costs and are the most widely used for paperback fiction and non-fiction. Common regular trim sizes include 5 x 8 in, 5.5 x 8.5 in (the most popular trade paperback format), and 6 x 9 in.

Large Trim Sizes

Large trim sizes are any dimensions exceeding 6.12 inches in width or 9 inches in height. These carry a higher per-page cost due to the additional paper used. Examples include 7 x 10 in (used for textbooks and workbooks), 8.5 x 8.5 in (popular for children’s books and illustrated titles), and 8.5 x 11 in (used for activity books and large print editions).

On Amazon.com, the B&W per-page rate for regular trim is $0.012 compared to $0.017 for large trim – a difference of 42%. For a 300-page book, this means a large trim costs $1.50 more to print than the same book in a regular trim. When printing in premium color, that gap widens: $0.065 per page (regular) vs $0.080 per page (large), a difference of $4.50 on a 300-page book.

Printing Costs Across All 14 Marketplaces

KDP’s printing cost rates are set independently for each marketplace and are not simply a currency conversion of the US rates. The fixed base cost and per-page rate both differ by region, reflecting local production and logistics costs. This means that the economics of a given book can be quite different depending on where it sells.

The table below shows printing costs for a 300-page black and white paperback with a regular trim across all supported marketplaces. Six European marketplaces – Amazon.de, .fr, .es, .it, .nl, .com.be, and .ie – share the same printing cost rates and are grouped together below.

Hardcover printing is available on Amazon.com, Amazon.co.uk, Amazon.de (and other EU stores that share DE rates), Amazon.pl, and Amazon.se only. On Amazon.com, a hardcover B&W book with 110 or more pages costs $5.65 + (page count x $0.012), making a 300-page hardcover $9.25 to print versus $4.60 for the same book in paperback.

KDP Royalty Rates Explained

For print books, KDP offers two standard royalty rates: 60% and 50%. The rate that applies to a given sale depends on the list price relative to a marketplace-specific threshold.

• If your list price is at or above the threshold, you earn 60% of the list price, minus the printing cost.
• If your list price is below the threshold, you earn 50% of the list price, minus the printing cost.

Using a 300-page B&W paperback on Amazon.com as an example: the printing cost is $4.60 and the threshold is $9.99. At a list price of $14.99 (above the threshold), the royalty is (0.60 x $14.99) – $4.60 = $8.99 – $4.60 = $4.39. At a list price of $8.99 (below the threshold), the royalty is (0.50 x $8.99) – $4.60 = $4.50 – $4.60 = -$0.10, which is a loss and KDP would not allow this price.

Expanded Distribution

Expanded Distribution is an optional program that makes your paperback available to retailers, bookstores, libraries, school libraries, and academic institutions beyond Amazon, through the Ingram distribution network. When Expanded Distribution is enabled, your book can be ordered by independent booksellers, public libraries, and educational buyers who order through Ingram’s wholesale catalog.

Enabling Expanded Distribution comes with a significant trade-off: the royalty rate drops to a flat 40% of the list price, minus printing costs. This applies regardless of what the list price is. There is no 50%/60% threshold distinction under Expanded Distribution.

Because the royalty rate is lower, your minimum viable list price is higher under Expanded Distribution. For the same 300-page B&W paperback on Amazon.com (printing cost $4.60), the minimum list price to break even under Expanded Distribution is $4.60 / 0.40 = $11.50, compared to $9.20 at the 50% rate or $9.99 to qualify for the 60% rate through standard distribution.

When Does Expanded Distribution Make Sense?

Expanded Distribution is not the right choice for every book. Consider it if:

• Your book targets an audience that actively shops at independent bookstores or uses library systems
• You are writing non-fiction, academic, or reference material likely to be purchased by institutions
• You have already priced your book high enough that the 40% rate still produces an acceptable royalty
• You want to test whether retail or library channels produce meaningful additional sales

Expanded Distribution is available for paperbacks only, not hardcovers. On Amazon itself, enabling Expanded Distribution does not change the royalty rate for Amazon sales – that still uses the standard 50%/60% structure based on the list price threshold.

Calculating Your Minimum List Price

KDP enforces a minimum list price for every book – a price below which you cannot publish, because KDP would be paying out more than it receives. The minimum list price is determined by your printing cost and the royalty rate structure in effect.

The general rule is:

• Standard Distribution (60%): Minimum price = Printing Cost / 0.60. But if this figure is below the 60% threshold, the minimum is instead Printing Cost / 0.50, since 50% is the rate that applies below the threshold.
• Standard Distribution (50%): Minimum price = Printing Cost / 0.50 (when the 60% minimum falls below the threshold).
• Expanded Distribution (40%): Minimum price = Printing Cost / 0.40.

The table below shows minimum list prices for a B&W paperback on Amazon.com at various page counts, under both standard and Expanded Distribution.

Notice that for books under roughly 480 pages on Amazon.com, the $9.99 royalty threshold is the binding minimum price for 60% rate eligibility – not the printing cost formula itself. Only for longer books does the formula-derived minimum exceed $9.99.

Tips for Maximizing KDP Print Royalties

Price for the 60% Royalty Tier

The jump from 50% to 60% royalty is significant. On a $9.99 book with a $4.60 printing cost, the 50% royalty is $0.40, while the 60% royalty is $1.39 – more than three times as much. Setting your price at or above the marketplace threshold is almost always worthwhile unless you have a strong reason to undercut it.

Consider Page Count as a Design Variable

Reducing your page count – through tighter layout, smaller margins, or a more compact font – can lower your printing cost and either improve your royalty at the same price point or allow a lower price that remains profitable. This is particularly useful for premium color books, where each page costs $0.065.

Trim Size Affects More Than Aesthetics

If your content can fit comfortably in a regular trim (up to 6.12″ x 9″), you will pay lower per-page rates than if you use a large trim. A 400-page B&W book in regular trim on Amazon.com costs $5.80 to print; the same book in large trim costs $7.80 – a $2.00 difference per copy.

Evaluate Each Marketplace Independently

The royalty on your primary marketplace may look attractive, but sales through other marketplaces – particularly Amazon.com.au, which has higher printing costs – may generate little to no profit at the same price. The KDP printing calculator on this page computes the royalty for all 14 marketplaces simultaneously so you can spot any markets where your pricing may be problematic.

Factor in Groundwood Paper if Available

For black and white books where paper color is not critical to the reading experience, groundwood paper’s 5% printing cost reduction is worth considering. On a high-volume book, the per-copy saving accumulates meaningfully over time.

Model Expanded Distribution Separately

Before enabling Expanded Distribution, run the numbers at your intended list price to confirm the 40% royalty rate still produces an acceptable return. Many authors find that the lower royalty rate under Expanded Distribution makes it profitable only at prices of $15 or above for most standard-length books.
