1What is Amazon BSR?
Amazon's Best Sellers Rank (BSR) is a numerical ranking that indicates how well a product sells compared to others in its category. A book with BSR #1 is the current top seller in that category, while a book with BSR #100,000 sells relatively fewer copies.
BSR is updated hourly and takes into account both recent sales velocity and historical sales data. This means a sudden spike in sales will quickly improve your BSR, but consistent sales over time also contribute to a better rank.
2How Does BSR Relate to Sales?
The relationship between BSR and sales follows a logarithmic curve. This means:
Numbers vary by marketplace and book format. Our calculator accounts for these differences.

Frequently Asked Questions
What is Amazon BSR (Best Sellers Rank)?
Amazon's Best Sellers Rank (BSR) is a number assigned to every product that indicates how well it sells compared to other products in the same category. A lower BSR means higher sales. The #1 ranked book is the current bestseller in its category. BSR is updated hourly based on recent and historical sales data.
How accurate is the BSR to sales calculator?
Our calculator uses community-derived formulas and publicly available data to estimate sales. While no calculator can be 100% accurate (Amazon doesn't publish official conversion rates), our estimates are based on extensive research and are generally within 20-30% of actual sales for most BSR ranges. Results should be used as directional guidance rather than exact figures.
Where do I find a book's BSR on Amazon?
To find a book's BSR, go to its Amazon product page and scroll down to the 'Product Details' section. You'll see 'Best Sellers Rank' followed by the rank number and category. Books can have multiple BSRs if they're listed in multiple categories.
Why do different book formats have different sales estimates?
Different book formats (Kindle, paperback, hardcover, audiobook) have different market sizes and sales volumes. Kindle eBooks typically have the largest market, followed by paperbacks. The same BSR in different formats represents different sales volumes because the total number of books sold in each format varies significantly.
How can I improve my book's BSR?
To improve your BSR: 1) Run promotional pricing during launch week, 2) Optimize your book's keywords and categories for discoverability, 3) Encourage readers to leave reviews, 4) Use Amazon Ads strategically to drive sales, 5) Build an email list to coordinate launch activities, 6) Ensure your book cover and description are compelling.
