About
RoyaltyPeek shows a quick royalty estimate on the Amazon book page you're already looking at — no switching to a calculator website, no copying numbers back and forth. Open any book on Amazon and a small card appears in the corner with: • Best Sellers Rank (BSR) and the book's top subcategory rank • Estimated sales per day • Estimated royalties per day, week, and month • Star rating, review count, publication year, and page count • Per-copy royalty for each available format (Kindle / paperback / hardcover) Built for KDP authors doing niche and competitor research. Set your own royalty numbers in Settings so the estimate matches your real margins. Honest by design: • Every figure is a rough ESTIMATE shown as a range, never a fake-precise number. • It reads only the page you have open. It does not use the Amazon API, does not scrape search results, and does not send your browsing anywhere. Privacy: RoyaltyPeek sends no page data anywhere. If you buy the paid version, license activation is handled by Lemon Squeezy — that is the only external connection. Note: sales and royalty figures are estimates based on public BSR-to-sales patterns and will not match actual sales exactly.
