KDP Royalty Ledger

Calculate KDP paperback printing costs, royalties, and minimum list price across ink types, trim sizes, and marketplaces.

Stop tabbing between Amazon's calculator and a spreadsheet every time you price a book. KDP Royalty Ledger is a small, single-purpose calculator for self-published authors and KDP sellers. Type in your trim size, page count, ink type, and list price — get your printing cost, royalty rate, royalty per copy, and minimum allowed list price instantly, live as you type. WHAT IT DOES Calculates printing cost across every KDP ink/paper type: black ink (cream or white paper), black ink (groundwood), premium color, and standard color Covers all 8 Amazon marketplaces (.com, .ca, .co.uk, .de/.es/.fr/.it/.nl/.ie/.be, .pl, .se, .com.au, .co.jp) with correct local currency Applies the correct 50%/60% royalty rate automatically based on your list price and marketplace, or the 40% Expanded Distribution rate Flags when your list price is below KDP's minimum, so you don't accidentally submit an unpublishable price Compare tab: save multiple trim size / ink / price versions of the same book side by side before you commit to a format Works completely offline — all your inputs stay in the popup WHY IT EXISTS Every number in this extension is pulled directly from Amazon's own published KDP help pages, not estimated. It's built by someone who publishes coloring books and low-content books on KDP and got tired of doing this math by hand for every new title and trim size option. PRIVACY This extension collects nothing. It has no analytics, no tracking, no network requests, no account, no login. The only data it stores is whatever you type into the Compare tab, saved locally on your own device using Chrome's storage API — never sent anywhere. See the full privacy policy for details. Not affiliated with, endorsed by, or officially connected to Amazon or Kindle Direct Publishing. Pricing data is sourced from Amazon's public KDP help pages and may lag behind Amazon's live rates — always confirm against KDP's own calculator before finalizing a price.
