Amazon BSR by Category: What Counts as Good?
A "good" Amazon BSR depends entirely on the category you're in. A BSR of 50,000 in the Kindle Store means you're selling roughly 3-5 copies a day, while that same number in Books (print) might mean one sale every few days. The category determines the scale, and ignoring that context leads to completely wrong assumptions about how a book is performing.
Why BSR Means Nothing Without Category Context
Amazon's Best Sellers Rank is a relative ranking. It compares your book's recent sales velocity against every other product in that same category store. The Kindle Store has millions of titles. The Audible Store has a different pool entirely. Print books sit in yet another.
A BSR of 10,000 in Kindle Store is a solidly selling book. That same rank in a niche subcategory like "Kindle Store > Crafts & Hobbies > Pottery" would actually be terrible, because there aren't that many books competing there. Context is everything.
Here's the part most guides skip: Amazon assigns BSR at the top-level store category, not at the subcategory level. Your book's BSR number reflects its performance against the entire Kindle Store or the entire Books store, not just your little corner of it.
BSR Benchmarks by Major Category
These ranges are approximate and based on patterns observed across thousands of titles. Sales fluctuate hourly, and BSR responds fast, so treat these as useful guidelines rather than gospel.
Kindle Store (eBooks)
- BSR 1-1,000: Bestseller territory. Roughly 25-100+ sales per day.
- BSR 1,000-10,000: Strong and consistent seller. Around 5-25 sales per day.
- BSR 10,000-50,000: Decent mid-list performance. 1-5 sales daily.
- BSR 50,000-100,000: A sale every day or two. Still earning, but modestly.
- BSR 100,000+: Sporadic sales. Maybe a few per week at best.
Books (Print)
- BSR 1-5,000: Selling well. Could be 10-50+ copies per day.
- BSR 5,000-50,000: Solid. A few copies daily.
- BSR 50,000-200,000: A copy every day or two.
- BSR 200,000+: Infrequent sales. One every few days to once a week.
Audible (Audiobooks)
The Audible store is smaller, so the numbers compress. A BSR under 5,000 is excellent. Under 20,000 is healthy. Past 50,000, sales are spotty.
The BSR Decay Problem
BSR doesn't just measure today's sales. It factors in recent sales history with a heavy bias toward the last few hours. This means your rank can swing wildly within a single day.
Sell 10 copies at 9 AM? Your BSR shoots up. Nothing sells for the next 8 hours? It drops significantly by evening. This is why a single BSR snapshot is nearly useless for judging a book's real performance.
What you want is trend data. Track BSR over days and weeks to see actual patterns. A book that bounces between 15,000 and 40,000 in Kindle Store is performing very differently from one that sits flatly at 200,000. One-time checks don't reveal this. If you're serious about understanding your book's trajectory, PublishRank's BSR Tracker lets you monitor rank changes over time across categories so you can spot real trends instead of reacting to noise.
Subcategory Rankings vs. Overall BSR
This confuses a lot of authors. You might see your book listed as #1 in "Science Fiction > Time Travel" but carrying a BSR of 45,000. That's not a contradiction.
The #1 ranking in a subcategory just means you're outselling the other books Amazon has placed in that specific subcategory. The BSR of 45,000 reflects your standing against the entire Kindle Store. Both numbers are real. They just measure different things.
Honestly, the subcategory ranking matters more for visibility. Being in the top 20 of a subcategory gets your book on a bestseller list page that customers actually browse. The overall BSR matters more for estimating revenue.
What "Good" Actually Means for KDP Authors
Forget chasing a specific BSR number. A "good" BSR is one that matches your goals and your category's competitiveness.
If you're a romance author with a 20-book catalog and each title sits between BSR 20,000 and 60,000 in Kindle Store, you're making real money. If you're a nonfiction author with one book at BSR 8,000, that single title might be earning you $500-$1,000 a month depending on your price point and royalty rate.
The authors who obsess over BSR without connecting it to actual revenue are missing the point. A BSR of 5,000 on a $0.99 book at 35% royalty earns less than a BSR of 30,000 on a $9.99 book at 70% royalty. Price and royalty structure matter just as much as rank.
Here's a practical framework: check your category, estimate daily sales from your BSR range using the benchmarks above, multiply by your per-unit royalty, and see if the math works for your goals. That's the only definition of "good" that matters.
BSR Differences You Should Know About
A few things that trip up newer authors:
- Free books get a separate BSR. If your book goes free during a KDP Select promo, it gets ranked on the Free chart, not the paid chart. A BSR of 500 on the free chart means lots of downloads, not lots of revenue.
- KU page reads affect BSR. Kindle Unlimited borrows and page reads count toward your Kindle Store BSR, not just purchases. This is why some KU-heavy genres show surprisingly low BSRs.
- Different marketplaces, different BSRs. Your BSR on Amazon.com is completely independent from Amazon.co.uk, Amazon.de, or any other marketplace. A book can rank well in one country and barely register in another.
- New releases get a temporary boost. Amazon's algorithm gives fresh titles a slight visibility push. Your BSR in the first 30 days may look better than your steady-state rank at 90 days.
Frequently Asked Questions
What is a good BSR on Amazon for books?
For Kindle eBooks, a BSR under 50,000 means consistent daily sales. Under 10,000 is strong. For print books, under 100,000 typically indicates at least a sale every day or two. But "good" depends on your category, price point, and goals. A BSR of 30,000 on a $12.99 book generates meaningful income over time.
Does Amazon BSR differ by category?
Yes. BSR is calculated within each top-level store (Kindle Store, Books, Audible, etc.), not across all of Amazon. A BSR of 20,000 in Kindle Store represents more sales than a BSR of 20,000 in Books because the Kindle Store has higher overall sales velocity. You can't compare BSR numbers across different stores directly.
How often does Amazon update BSR?
Amazon updates BSR hourly for books that are selling regularly. For books with infrequent sales, updates may happen less often. This is why your rank can change dramatically throughout a single day, especially after a sales spike or a dry spell of several hours.
How many sales does it take to hit BSR #1 in a category?
For a small Kindle subcategory, sometimes just 5-10 sales in a short window can push you to #1 in that subcategory. For the overall Kindle Store #1 spot, you'd need hundreds or thousands of sales per day. The required volume depends entirely on what the current #1 book is selling and the overall activity in that category.
Do Kindle Unlimited reads count toward BSR?
Yes. KU borrows and page reads factor into your Kindle Store BSR alongside paid purchases. This is why books enrolled in KDP Select often show better BSR numbers than their paid-sales-only equivalents, particularly in genres like romance, thriller, and LitRPG where KU readership is heavy.
