Why do so many authors price ebooks at $2.99?

Because $2.99 is the floor of the 70% royalty window on Amazon KDP. Anything priced below $2.99 (or above $9.99) drops to the 35% royalty rate, so a book at $2.98 can actually earn less per copy than the same book at $2.99. That single penny is a real cliff, which is why the $2.99 price point clusters so heavily.

What is the ebook delivery fee and when does it matter?

At the 70% royalty tier, KDP deducts a delivery fee based on your file size, commonly cited at roughly $0.15 per megabyte. For a mostly-text novel this is a few cents and barely noticeable. For an image-heavy book (a cookbook, a photo book, a heavily illustrated guide) the file can be large enough that the delivery fee visibly eats into the 70% royalty, which is one reason those books are often priced higher.

How is print royalty calculated?

For paperback and hardcover, your royalty is roughly 60% of the list price minus the printing cost. Printing cost is driven mainly by page count and interior color, so a thick book carries a high print cost that forces a higher list price just to leave any margin. Authors of long or full-color books regularly report per-unit margins near zero when they try to hold a competitive price.

Why is color printing so expensive to price around?

Color interior printing costs far more per page than black-and-white, and for a long full-color book the per-unit print cost can climb past $12. Because your royalty is a share of list minus that cost, a $12+ print cost means you must either price the book very high or accept almost no margin. This is the documented reason many color books are priced well above their black-and-white peers or released as ebooks first.

Pricing a self-published book: royalty tiers, cliffs, and the real math

By Tracy Atkins, founder of BookDesigner.ai and BookDesignTemplates.com · 15+ years of print files, 70,000+ authors · Updated July 18, 2026

The short answer: book pricing is not a taste decision, it is a math problem with hidden cliffs. On ebooks, the 70% royalty rate applies only between $2.99 and $9.99, so $2.98 can pay you less than $2.99. At the 70% tier, KDP also deducts a per-megabyte delivery fee that image-heavy books feel. In print, your royalty is roughly 60% of list minus the print cost, and print cost rises with page count and color, sometimes past the point where any sane price leaves a margin. Price to the math first, then to the market.

The ebook cliff nobody warns you about

Amazon KDP pays two ebook royalty rates: 70% and 35%. The 70% rate is available only when your list price sits between $2.99 and $9.99. Step outside that band in either direction and you drop to 35%. The consequence is a genuine cliff at the bottom edge: a book priced at $2.98 earns 35% of $2.98 (about $1.04), while the same book at $2.99 earns 70% of $2.99 (about $2.09). One extra penny of list price roughly doubles your royalty. That is why $2.99 is the most crowded price point in self-publishing, and why pricing an ebook at $0.99 or $1.99 is a deliberate marketing choice (visibility, series hooks) rather than a revenue-maximizing one.

The same cliff exists at the top. Cross $9.99 and you fall back to 35%, so a $10.99 ebook has to clear a surprisingly high bar to out-earn a $9.99 one on a per-copy basis.

The delivery fee hiding inside the 70% tier

The 70% rate comes with a catch that the 35% rate does not: a delivery fee based on file size. The figure most commonly cited is roughly $0.15 per megabyte, deducted from your royalty before you are paid. For a plain-text novel weighing a fraction of a megabyte, this is a rounding error of a few cents. For an image-heavy book, it is not. A cookbook, a photography title, or a richly illustrated nonfiction book can carry a file large enough that the delivery fee becomes a visible line item against every sale. Treat the fee as hedge-worthy (Amazon can revise the rate), but plan for it: the heavier your interior, the more the 70% tier quietly costs you, and the more sense a higher price or a compressed image set makes.

Print royalty: 60% of list, minus a cost you do not control

Print math works differently. Your royalty is approximately 60% of the list price minus the printing cost, and the printing cost is set by the printer, not by you. The dominant driver is page count: more pages means more paper and more press time, so a long book carries a high fixed print cost on every single copy. Because your take is a share of what is left after that cost, a thick book forces a higher list price simply to leave any margin at all.

This is where author complaints cluster. It is common to see documented reports of writers with long books discovering that at a competitive shelf price their per-copy margin is near zero, or that to earn a meaningful royalty they would have to price the paperback above what readers in their category will pay. The printing cost is a floor you cannot negotiate away, and it climbs with every chapter you add.

The color problem

Color makes the print floor much higher. Full-color interior printing costs far more per page than black-and-white, and for a long color book the per-unit print cost can climb past $12. Run that through the 60%-of-list-minus-cost formula and the result is stark: to clear any margin on a book that costs $12+ to print, you must price it very high, and at that price the book may simply not sell in its category. This is the documented reason many color titles are priced well above their black-and-white peers, released as ebooks first, or reworked to use color sparingly. If your book truly needs full color throughout, price it with the print cost in front of you before you fall in love with a number.

Common price bands, as a starting point

These are ranges the market commonly supports, not rules. Your category, length, and print cost move them.

Format	Commonly priced	What drives it
Ebook (fiction)	$2.99–$5.99	The 70% window; series and genre norms
Ebook (nonfiction)	$4.99–$9.99	Perceived value; staying under the $9.99 ceiling
Paperback	$9.99–$19.99	Page count and print cost; category expectations
Hardcover	$24.99–$34.99	Higher print cost; gift and library positioning
Full-color	Often $20+	Per-unit print cost that can exceed $12

The honest way to use this table: find your format, look up your real print cost, and check that your intended price leaves a royalty you can live with before you check what looks good on a product page.

How to actually set your price

Get your real print cost first. Enter your final page count, trim, and color choice into the printer's calculator. That cost is the floor everything else sits on.
Stay inside the ebook window on purpose. $2.99 to $9.99 for the 70% rate, and remember the per-megabyte delivery fee if your file is heavy.
Back into the print list price. Decide the royalty you need, add the print cost, and divide by 0.6 to see the list price the math demands, then sanity-check it against your category.
Let color and length inform format. If the print cost makes a sane price impossible, that is a signal to trim pages, rethink color, or lead with the ebook.
