KDP Paperback Royalty Calculator: Print Cost vs Profit

Your KDP paperback royalty equals your list price minus Amazon's 40% cut minus your printing cost. That's the formula. But the printing cost depends on page count, ink type, trim size, and marketplace, so the actual number you pocket can shift dramatically based on choices you make before you ever hit publish. This guide breaks down every variable so you can price your paperback with confidence instead of guesswork.

The KDP Paperback Royalty Formula

Amazon uses a fixed-rate royalty of 60% for paperbacks. Here's how the math works:

Royalty = (List Price × 0.60) − Printing Cost

So if your list price is $14.99 and your printing cost is $3.55, your royalty is ($14.99 × 0.60) − $3.55 = $5.44 per copy sold on Amazon.com.

Simple enough. The tricky part is the printing cost, because Amazon doesn't charge a flat rate. They charge a fixed cost plus a per-page cost, and both numbers change depending on your book's specs.

How Amazon Calculates Printing Cost

As of 2024, KDP uses this structure for US printing:

• Black and white interior: $0.85 fixed + $0.012 per page
• Premium color interior: $0.85 fixed + $0.065 per page
• Standard color interior: $0.85 fixed + $0.040 per page

A 200-page black-and-white book costs $0.85 + (200 × $0.012) = $3.25 to print. A 200-page premium color book costs $0.85 + (200 × $0.065) = $13.85. That's a massive difference, and it's why low-content and coloring book creators need to be especially careful with pricing.

These rates apply to the US marketplace. Printing costs for Amazon.co.uk, Amazon.de, Amazon.co.jp, and expanded distribution channels are different and generally higher. If you sell internationally, your per-copy royalty will be lower on those marketplaces even at the same list price.

What Affects Your Profit the Most

Page Count

Every page costs money to print. If you can trim 20 pages of fluff from a 300-page manuscript, you save $0.24 per copy on black-and-white interior. That's $240 saved per 1,000 copies. Not life-changing, but not nothing either. For color interiors, cutting 20 pages saves $1.30 per copy. Now we're talking.

Ink Type

Black and white is the cheapest option by far. If your book doesn't need color, don't use it. Even a few color images will push you into color pricing for the entire book. Consider whether those images could work in grayscale.

Trim Size

Trim size doesn't directly change Amazon's per-page rate, but it affects your page count. A larger trim size means fewer pages for the same word count. A 60,000-word novel in 5"×8" might run 280 pages. The same text in 6"×9" might be 220 pages. That difference saves you about $0.72 per copy in printing costs.

List Price

This is the lever you actually control. Price too low and your royalty evaporates. Price too high and nobody buys. The sweet spot depends on your genre and competition. A 200-page nonfiction paperback at $14.99 earns you roughly $5.74. Drop the price to $9.99 and you're looking at $2.74. That's half the royalty for a 33% price reduction. The math is unforgiving at the low end.

Expanded Distribution: A Different Calculation

When you enable expanded distribution, Amazon sells your book through third-party retailers, libraries, and academic distributors. Your royalty rate stays at 60%, but the printing cost increases. Amazon adds a surcharge because expanded distribution books are printed at different facilities.

In practice, your expanded distribution royalty will be significantly lower. Many authors with books under $12.99 find their expanded distribution royalty is close to zero or even forces a minimum price increase. Always calculate both channels separately before setting your price.

Running the Numbers Before You Publish

You can use the Amazon KDP pricing calculator inside your KDP dashboard, but it only works after you've uploaded your manuscript and entered your book details. That's late in the process to discover your pricing doesn't work.

A better approach is to calculate your royalty before you finalize anything. The Royalty Calculator at PublishRank lets you plug in your page count, ink type, marketplace, and list price to see your exact printing cost and royalty instantly. You can test different price points and page counts to find the combination that actually makes financial sense for your book.

I'd recommend running these numbers at three stages: when you're outlining your book (to set realistic profit expectations), when you're formatting (to decide on trim size and ink type), and right before publishing (to finalize your list price).

Common Pricing Mistakes That Kill Paperback Profits

Pricing to match ebook royalties. Your ebook at $4.99 earns you about $3.49 at the 70% royalty rate. To earn the same $3.49 on a 200-page paperback, you'd need to price it at around $11.23. Many authors instinctively price their paperback too close to their ebook price and wonder why they earn $0.50 per sale.

Ignoring international printing costs. Your $14.99 book might earn $5.74 on Amazon.com but only $2.10 on Amazon.co.uk after currency conversion and higher printing costs. If a large chunk of your audience is international, factor that in.

Forgetting about author copies. Author copies cost the printing price plus shipping. They're cheap, but they're not free. If you plan to sell at events or send review copies, budget for this separately.

Setting your price at the minimum. KDP has a minimum list price that covers printing cost only. Your royalty at minimum price is literally $0.00. Always price above the minimum by enough to earn a meaningful royalty per sale.
