Frequently Asked Questions

How does Amazon calculate KDP Paperback Royalties?

For paperbacks and hardcovers sold on Amazon marketplaces, KDP offers a fixed 60% royalty rate on the list price you set. However, Amazon deducts the printing cost from your 60% share. The formula is:
(List Price x 0.60) - Print Cost = Net Royalty.
If you opt for Expanded Distribution (selling to bookstores and libraries), the royalty rate drops to 40%.

Why is my Profit Margin so low?

Many new authors are surprised by low profit margins on print books. This happens because high page counts (e.g., over 300 pages) or premium color interior ink significantly increase the underlying print cost. If your book costs $6.00 to print and you price it at $10.00, your 60% gross royalty is $6.00. After subtracting the $6.00 print cost, your net royalty is exactly $0.00. To fix this, you must increase the list price or reduce the print cost (fewer pages, black and white ink).

Do I pay the Print Cost upfront?

No. The beauty of Print-on-Demand (POD) is that there are zero upfront costs. When a customer buys your book on Amazon, Amazon takes the payment, prints the book, deducts the printing cost and their 40% platform share, and deposits the remaining net royalty directly into your bank account. You never have to buy inventory or ship books yourself.

What is a good profit margin for KDP books?

While it varies, most independent authors aim for a net royalty of $2.50 to $4.50 per paperback sold. This usually translates to a profit margin of 20% to 30%. Maintaining a healthy margin is exclusively critical if you plan to run Amazon Ads, as advertising costs will eat into your profits quickly.
