Amazon BSR to Sales Calculator

Turn any book's Best Sellers Rank into estimated copies sold per day and per month, for print books and for Kindle ebooks on Amazon.com.

Where to find the BSR

Open the book's page on Amazon.com and scroll to Product details. "Best Sellers Rank: #25,000 in Books" is the number to use. Use the overall rank in Books or Kindle Store, not the smaller category ranks below it.

BSR to sales table

How accurate is it?

Amazon does not publish sales, so every BSR calculator is an estimate. This one follows commonly published rank tables for each store: around 120 Kindle sales a day at rank #1,000, about 17 at #10,000 and about one a day at #100,000 (print books: roughly 55, 8 and 1). The rank also moves every hour, so a single snapshot can mislead: check a book on several days, and compare books with each other rather than trusting one number.

Kindle Unlimited page reads also lift the rank of ebooks, so a Kindle book can rank well without selling that many copies.

FAQ

What is a good BSR for a self-published book?

Under #100,000 in Books means steady sales of roughly 30 or more a month. Under #10,000 is a strong seller with several hundred a month.

How do I know if a niche is worth it?

Look at the ranks of the top 10 books for your keyword, not just one. Nichely does that in one click and adds their reviews and how many are self-published.
