Book pricing is part math, part psychology, and part genre convention. Setting the right price can directly impact both your sales volume and your earnings per book.

For Kindle ebooks, Amazon’s royalty structure is the most important factor. Books priced between $2.99 and $9.99 earn a 70% royalty, while books priced outside that range earn only 35%. This difference is significant — a $2.99 ebook earns roughly $2.09, while a $1.99 ebook earns about $0.70. Unless you have a specific strategy, staying within the 70% range is usually the best choice.

Genre expectations play a major role in pricing. Readers are used to seeing certain price ranges depending on the category:

• Romance, thriller, sci-fi: typically $2.99–$5.99
• Literary fiction and narrative nonfiction: often $4.99–$9.99
• Specialized nonfiction (business, technical): can be priced higher

A practical approach is to review top-selling books in your category on Amazon and match the general pricing range your target readers expect.

Print pricing works differently. Your minimum price must cover printing costs plus the platform’s share. Tools like Amazon KDP’s pricing calculator show your royalty at different price points. If your royalty is zero or negative, your price is too low.

Typical print pricing ranges:

• Paperbacks (200–350 pages): $12.99–$17.99 (fiction)
• Paperbacks (nonfiction): $14.99–$19.99
• Hardcovers: $22.99–$29.99

Pricing too low can hurt perceived value. A very low print price may signal low quality to readers. Your book is often displayed alongside traditionally published titles, so pricing within expected ranges builds credibility.

Pricing psychology also matters. If your ebook is $4.99 and your paperback is $15.99, the ebook feels like a strong value. This “anchoring” effect can increase ebook sales while still offering a print option. Some authors price hardcovers higher to make the paperback appear like the most balanced choice.

Kindle Unlimited changes pricing dynamics. If you are enrolled in KDP Select, many readers access your book through KU rather than buying it outright. In that case, your earnings come from pages read rather than the list price, so price sensitivity may matter less.

Pricing should not be static. Review your pricing periodically. If sales slow, test temporary discounts or promotional tools like Kindle Countdown Deals to see if increased volume offsets a lower price.
