Paperback royalties on KDP: how print cost shapes your price

How KDP paperback royalties work: the 50% and 60% rates, how page count, ink, and trim set printing cost, worked examples, and pricing for margin.

Paperback royalties on Amazon KDP work differently from ebook royalties. Instead of simply a percentage of the list price, you earn a percentage of the list price with the cost of printing each copy subtracted from it. That makes printing cost one of the biggest factors in your price, and it’s set by decisions you make long before you publish: page count, ink, and trim size.

The figures below are for Amazon.com and were current when this was written. KDP shows your exact printing cost and royalty during setup, so confirm them there before you set a price.

The formula

KDP’s paperback royalty is:

(royalty rate × list price) − printing cost = royalty

The royalty rate depends on the list price. Since June 2025, paperbacks sold on Amazon’s marketplaces earn:

  • 60% when the list price is at or above a threshold, which is $9.99 on Amazon.com
  • 50% when the list price is below it

Other marketplaces have their own thresholds, such as £7.99 in the UK, €9.99 in the euro stores, and $13.99 in Canada and Australia.

If you enable Expanded Distribution, which makes the book available to other retailers and libraries, those sales earn 40% of the list price, less the printing cost.

What sets the printing cost

KDP’s printing cost is a fixed charge per book plus a charge per page, and it varies with ink and trim size. On Amazon.com:

InkPagesRegular trimLarge trim
Black24 to 110$2.30 flat$2.84 flat
Blackover 110$1.00 + $0.012 per page$1.00 + $0.017 per page
Standard color72 to 600$1.00 + $0.0255 per page$1.00 + $0.0402 per page
Premium color24 to 40$3.60 flat$4.20 flat
Premium color42 and over$1.00 + $0.065 per page$1.00 + $0.08 per page

KDP counts any trim wider than 6.12 inches or taller than 9 inches as large. A 6 x 9 inch novel is regular; an 8.5 x 11 inch workbook is large.

Worked examples

A 300-page novel

A 6 x 9 inch novel with 300 pages in black ink costs $1.00 + (300 × $0.012) = $4.60 to print.

List priceRateRoyalty per sale
$9.9850%$0.39
$9.9960%$1.39
$12.9960%$3.19
$14.9960%$4.39

One cent at the threshold changes the royalty by a dollar. If comparable books in your genre sell at $9.99 or above, pricing just under the line costs you far more than it saves the reader.

A short book

A 150-page, 5 x 8 inch book in black ink costs $1.00 + (150 × $0.012) = $2.80 to print. At $8.99, with the 50% rate, the royalty is about $1.70. At $9.99, with the 60% rate, it’s about $3.19.

A color picture book

A 32-page, 8.5 x 8.5 inch picture book in premium color costs a flat $4.20 to print, because a square trim that wide counts as large. At $12.99, the royalty is about $3.59; at $9.99, it’s about $1.79.

Expanded Distribution

The 300-page novel at $14.99 earns about $1.40 per copy through Expanded Distribution (40% × $14.99 − $4.60), compared with $4.39 on Amazon. Decide whether the wider reach is worth the smaller margin, and check that your price clears the minimum for that channel.

The minimum list price

KDP won’t let you set a price where the royalty would be negative. The minimum is the printing cost divided by the royalty rate. For the 300-page novel, that’s $4.60 ÷ 0.50 = $9.20, because prices below $9.99 earn 50%.

That means books with high printing costs can’t be priced low at all. Before you commit to a long book in color, check that the minimum price is one readers in your genre will pay.

Ways to improve the margin

  • Choose the trim with cost in mind. A slightly larger regular trim can reduce the page count without moving into the large-trim tier.
  • Check the interior layout. Generous margins and readable type matter, but excess spacing, stray blank pages, and oversized chapter openings add pages without adding value.
  • Use black ink unless color is essential. A few color diagrams can often be redrawn in grayscale.
  • Price at or above the threshold when your genre supports it.

Don’t shrink the type or the margins below what’s comfortable to read. A cramped book saves cents per copy and costs you reviews.

Setting a price readers accept

The royalty math tells you what a price earns, not whether readers will pay it. Before you settle:

  1. List comparable paperbacks. Note the list prices of five to ten recent, similar books in your genre and at a similar length.
  2. Find the range. Most genres have a band that readers treat as normal for a paperback of a given length.
  3. Place your book in the range. A longer book, a series starter, or a debut may sit at different points within it.
  4. Check your royalty at that price. If it’s too thin, look at trim, layout, and ink before you push the price above what readers expect.

Hardcovers follow similar rules

KDP’s hardcovers use the same structure: a royalty rate of 50% or 60% depending on the list price, minus a printing cost. Hardcovers cost more to print, so the minimum price is higher, and KDP’s hardcover option has its own page-count range and trim sizes. Check the hardcover printing cost in KDP’s setup rather than estimating it from the paperback.

Paperback prices in other marketplaces

KDP lets you set the paperback’s price for each Amazon marketplace, or base the others on your US price. Converted prices often land on awkward numbers, and the thresholds differ by marketplace, so check each one. A price that clears the 60% threshold in the US may fall just below it in the UK or Canada after conversion. Printing costs also differ by marketplace, and KDP lists them separately for each one, so the same book can earn a different royalty per copy in each store.

How print and ebook prices interact

KDP’s 70% ebook royalty requires the ebook to be priced at least 20% below the list price of the print edition on Amazon, so set the paperback price first and the ebook price after. For the ebook side, see pricing an ebook on KDP. If you haven’t chosen a trim size yet, trim sizes and interior formatting basics covers the options.

Common paperback pricing mistakes

  • Carrying ebook pricing habits over to print, where the printing cost changes the math
  • Pricing a few cents below the 60% threshold out of habit
  • Forgetting that a revised interior with more pages raises both the printing cost and the minimum price
  • Setting one US price and letting other marketplaces convert to awkward amounts

Each one is easy to catch if you check the royalty preview after every change.

Author copies

When you order author copies, you pay the printing cost plus shipping and any applicable taxes. Author copies don’t earn royalties or count toward your sales rank, but they’re often the cheapest way to get books for events, giveaways, and local shops.
