Book Royalties Explained: How Authors Get Paid

How Authors Actually Make Money from Book Sales

If you’re thinking about publishing a book, one question tends to sit at the center of everything else: how do authors actually make money? To answer that, we need to look at book royalties explained—what they are, how they’re calculated, and what they actually mean for your earnings.

Royalties and pricing can feel confusing, especially when different publishing models use different terminology and promises—like “100% royalties”—without clearly showing how those numbers translate once printing costs, retailer discounts, and distribution fees are factored in.

At Atmosphere Press, we believe authors should understand how book revenue works before they publish. In this guide, we break down how royalties actually work, why a 90% model often leads to stronger real earnings, and how pricing is set to perform across Amazon and wider distribution.

How Do Book Royalties Work?

At its simplest, a royalty is the amount of money you earn each time your book sells.

That number is determined by a simple equation used across the publishing industry:

Retail Price – Printing Cost – Distribution Fees = Royalty

Here’s what that means in practice:

➜ Retail price is the price readers see when they buy your book

➜ Printing cost depends on factors like page count, trim size, and whether the book is printed in black-and-white or color

➜ Distribution fees are taken by platforms like Amazon (KDP) or Ingram, as well as retailers like bookstores

What’s left after those costs are deducted is your royalty.

Why 90% Royalties Are Often Better Than 100%

At first glance, “100% royalties” sounds like the best possible deal. After all, keeping everything you earn seems ideal.

However, in publishing, that number can be misleading without context.

What “100% Royalties” Usually Means

When a platform advertises 100% royalties, it typically means:

➜ You receive 100% of the profit after printing and distribution costs

➜ You are responsible for setting pricing, often without strategic guidance

➜ Distribution may be limited (for example, primarily Amazon-only)

In other words, 100% of a smaller, less optimized margin—and often with less support behind the scenes.

What Lower-Royalty Models Mean

Traditional publishing typically offers:

➜ 5–15% royalties on the retail price

➜ No control over pricing or distribution decisions

➜ Advances that may never earn out

While these models can offer prestige, they often result in lower long-term earnings per book.

Where 90% Fits In & Why It Works

Atmosphere Press uses a 90% royalty model, designed to balance profitability with professional support.

This percentage applies to net revenue after printing and distribution costs, ensuring transparency about what authors actually earn per sale.

Here’s what that means in practice:

➜ You retain the vast majority of earnings from each sale

➜ Pricing is strategically set to maximize real royalties—not just percentages

➜ Distribution includes both Amazon (KDP) and Ingram

➜ You receive guidance throughout the process—you’re not navigating pricing alone

The Real Comparison

The most important question isn’t: “What percentage do I get?”

The most important question is: “What does that percentage translate to in real dollars—and how often will my book sell at that rate?”

A well-priced, widely distributed book earning 90% of optimized royalties will typically outperform a book earning 100% in a limited or poorly structured system.

What Percentage Do Retailers Take from Book Sales?

If you’re not receiving 100% of your book’s retail price, it’s because multiple parties are involved in getting that book into readers’ hands—and each takes a standard share.

Amazon (KDP): ~40% of the retail price

Ingram distribution: 55% wholesale discount (industry standard)

These percentages reflect how the broader book market functions—not unique fees from Atmosphere Press. Atmosphere Press builds its pricing strategy around these fixed industry standards rather than trying to work around them.

Why These Percentages Exist

Amazon (KDP)

✧ Acts as both retailer and distributor

✧ Provides direct-to-consumer sales

✧ Offers high visibility and global reach

Ingram (Expanded Distribution)

✧ Supplies bookstores, libraries, and independent retailers

✧ Uses a wholesale model with a 55% discount

✧ Expands availability beyond Amazon

That 55% is shared between the retailer & the distributor (Ingram).

The 55% Wholesale Discount

Bookstores generally won’t stock books without a standard wholesale discount.

➜ 55% is the expected norm

➜ Lower discounts can limit bookstore availability

This isn’t just a fee—it’s what allows your book to exist in the wider retail ecosystem.

How Is the Retail Price of a Book Determined?

Book pricing is a strategic process designed to balance reader expectations, production costs, and author earnings.

At Atmosphere Press, pricing is set during the paperback proof stage in collaboration with your publishing team, using real production data and distribution models.

Step 1: Start with Paperback Economics (Amazon / KDP)

When paperback files are uploaded to Amazon KDP, we can see:

✦ The exact print cost

✦ The distribution fee Amazon takes

From there, we set a retail price targeting:

✦ $6–$7 in royalties per sale on Amazon

This range:

➜ Keeps pricing competitive

➜ Ensures meaningful earnings per sale

➜ Avoids overpricing that could reduce sales

Authors are part of this process, but pricing is guided by market data and proven performance.

Step 2: Align for Expanded Distribution (Ingram)

Next, we ensure the same retail price works within Ingram’s model.

Because of the 55% wholesale discount, margins are tighter. We aim for:

✦ $2–$3 in royalties per paperback sale through Ingram

This is confirmed using Ingram’s compensation tools to ensure the book remains viable across bookstores, libraries, and independent retailers.

Step 3: Set Hardcover Pricing Strategically

Hardcover pricing is based on the paperback as a reference point.

Typically:

➜ Hardcover is priced about $12 higher than the paperback (as of April 2026)

➜ This maintains a $2–$3 royalty range through Ingram

This may vary depending on:

✦ Page count

✦ Trim size

✦ Color printing

Because hardcover files aren’t finalized during paperback proofing, we use modeling tools to confirm pricing consistency in advance.

Why Pricing Matters

Every pricing decision answers three questions:

1. Is this price competitive for readers?

2. Does it generate meaningful earnings for the author?

3. Does it work across both Amazon and expanded distribution?

Balancing these ensures your book is both competitive in the market and profitable over time.

What Percentage of Book Sales Happen on Amazon?

For most modern authors, Amazon is the primary sales channel.

Approximately 70–80% of book sales happen on Amazon for many independently published titles

Why Amazon Dominates

✧ Search-driven discovery

✧ Familiar purchasing experience

✧ Global reach

✧ Algorithmic recommendations

Where the Other Sales Come From

The remaining 20–30% typically comes from:

✧ Independent bookstores

✧ Libraries

✧ Online retailers beyond Amazon

✧ Special orders through Ingram

Why This Matters

This is why pricing and royalties are structured the way they are:

➜ Amazon is optimized for higher per-sale earnings ($6–$7)

➜ Expanded distribution is optimized for reach ($2–$3 per sale)

Amazon drives most sales—but expanded distribution ensures your book reaches beyond a single platform.

Understanding the Bigger Picture of Book Revenue

When you understand how royalties, pricing, and distribution work together, publishing becomes much more strategic.

At Atmosphere Press, that means:

✦ Structuring royalties so authors retain the majority of earnings

✦ Pricing books to perform across multiple sales channels

✦ Ensuring each sale contributes to both profitability and visibility

When these elements are aligned, your book isn’t just available—it’s positioned to succeed.

Frequently Asked Questions About Royalties, Pricing, and Book Sales

How do royalties work in publishing?

Royalties are the amount an author earns per book sale after printing and distribution costs are deducted.

Is 100% royalties better than 90%?

Not necessarily. “100% royalties” usually apply after costs and often within limited distribution, while a 90% model can produce higher real earnings across more sales channels.

What percentage does Amazon take from book sales?

Amazon typically takes around 40% of the retail price for paperback sales through KDP.

What is a 55% wholesale discount in publishing?

It’s the industry-standard discount that allows bookstores and retailers to purchase books for resale.

Why are royalties lower through bookstores than Amazon?

Bookstores rely on wholesale pricing through distributors like Ingram, which reduces per-book royalties but increases reach.

How is my book’s retail price decided?

It’s based on printing costs, distributor fees, and target royalty ranges—typically $6–$7 per Amazon sale and $2–$3 through expanded distribution.

Do I need to choose between Amazon and wider distribution?

No. A balanced approach includes both—Amazon for higher earnings per sale and expanded distribution for broader reach.
