Amazon.com Printing Costs for US Authors

Amazon's US print-on-demand facility is the backbone of KDP paperback publishing. The base printing cost for a black-and-white interior book on Amazon.com is $0.85 plus $0.012 per page. For a typical 250-page novel, that works out to $3.85 in printing costs. Standard colour printing runs $0.85 base plus $0.065 per page, while premium colour is $0.85 base plus $0.075 per page — a substantial difference that impacts your minimum viable price.

The $9.99 royalty threshold on Amazon.com is the most critical number for US paperback authors. Books priced at or above $9.99 earn 60% royalty, while those below earn only 50%. For a 250-page B&W book with $3.85 printing cost, pricing at $9.99 yields a royalty of $2.14 at 60%, compared to just $1.15 at $8.99 and 50%. That single dollar increase in list price nearly doubles your per-unit earnings.

US trim sizes follow industry standards, with 6" × 9" being the most popular for fiction and non-fiction trade paperbacks. Amazon.com supports over 30 trim size options, but the most cost-effective are 5" × 8", 5.5" × 8.5", and 6" × 9". Larger trim sizes like 8.5" × 11" are available for workbooks and illustrated books but carry higher base costs. The calculator above lets you compare costs across all available sizes.

Expanded distribution through Amazon.com extends your paperback to third-party sellers, bookshops, and libraries via Ingram's network. The royalty rate drops to 40% minus printing costs for expanded distribution sales. For most US authors, expanded distribution only makes financial sense for shorter books (under 200 pages) where printing costs are low enough to maintain a meaningful margin at the reduced rate.

Amazon frequently updates its US printing infrastructure, and costs occasionally shift. The rates in this calculator reflect the June 2025 restructure, which introduced the tiered royalty system. Always verify your actual printing cost in the KDP dashboard before finalising your list price, as Amazon may apply regional surcharges during high-demand periods or for non-standard trim sizes.
