The U.S. Amazon marketplace has hundreds of millions of products listed across 20 categories.

And while those numbers may seem incredible, what’s more incredible is that the vast majority of items available on Amazon (that have made one or more sales) is awarded a special ranking called the Best Sellers Rank (BSR).

But what is the Best Sellers Rank? And what does it mean for your Amazon FBA business? In this article, we’ll dive deep into what the BSR actually is and how understanding its function can benefit your business.

  • What is Amazon Best Sellers Rank?
  • How is Amazon Best Sellers Rank calculated?
  • What is the difference between Amazon Best Sellers Rank and organic ranking?
  • How can I use Amazon Best Sellers Rank to estimate sales?
  • What tools are available to calculate sales from Amazon Best Sellers Rank?

How to Quickly Calculate Amazon BSRs

What is Amazon Best Sellers Rank?

An Amazon Best Sellers Rank (BSR) is a number that nearly every product in its multi-million product catalog is awarded once the item has had at least one sale. For that reason, the BSR is a good indicator of how well a product is currently selling on Amazon.

The better the product’s BSR, the better its sales.

For example, a product ranked #1 has much higher sales than a product ranked #200,000. 

However, the BSR only applies to how a product sells in a particular category. In other words, products don’t have an overall BSR, comparing their sales to every other product on Amazon.

But, since many products sell in multiple categories on Amazon, it is possible for an item to have more than one BSR. Particularly when you take into account that nearly every department and sub-category on Amazon has its own individual best sellers ranking system.

So, a product on Amazon can have a BSR of 2,000 in Kitchen & Dining, while the exact same product can have an Amazon Best Sellers Rank of 20,000 when sold in Toys & Games.

Note: Some products on Amazon are not given BSRs. This is fairly common for electronics.  

How is Amazon’s Best Sellers Rank calculated?

Although Amazon doesn’t reveal exactly how the Best Sellers Rank is calculated, there are a number of factors that contribute to it, including:

  • Current and historic sales
  • Product price changes and promotions
  • Competitive products

The BSR reflects current sales trends, as well as historical sales volume, and is updated hourly.

For example, if a product has 10 units of sales in one hour but drops to only one unit sale the next, that doesn’t mean it will automatically drop down to a BSR that’s for products that only sell one per hour. Instead, the BSR algorithm will take into account both sales velocities.

Let me show you what I mean using some hypothetical numbers.

An example of how Amazon Best Sellers Rank works:

  • Product A is currently ranked #500 in Amazon’s Patio, Lawn & Garden category. It just sold eight products in the last hour.
  • At the same time, Product B is currently ranked #1000 in Amazon’s Patio, Lawn & Garden category. That product sold four products in the last hour.
  • In the next hour,  Product A sells only four products and Product B sells eight products. 
  • Logically, you’d think that the two would swap BSRs, right? In other words, product A would be #1000 in Patio, Lawn & Garden and Product B would be #500 in Patio, Lawn & Garden.
  • However, Product A‘s Amazon Best Sellers Rank might instead go to #600. And Product B’s Amazon Best Sellers Rank might go to #900.

The reason that the products don’t have drastic fluctuations in their Amazon Best Sellers Rank despite essentially “switching places” with their hourly sales is that Amazon’s Best Sellers Ranking system takes into account the number of historical sales the product had.

In the example above, while Product A may have dropped half its hourly sales count, it typically does an average of 8. So even a momentary drop isn’t enough to totally deplete its BSR.

What other factors does Amazon consider in its Best Sellers Rank?

Some Amazon FBA sellers have noticed that when they offer their products at a discount via a promotion or a coupon, the product’s Best Sellers Ranking does not change as quickly even with high sales volume.

While there is no official word from Amazon yet regarding this practice, experts suspect this factor may have been put into place to deter sellers from “gaming” the Best Sellers Rank system using promotional giveaways to create phony sales velocity.

What is the difference between Amazon Best Sellers Rank and organic ranking?

One big thing that a lot of new sellers confuse when they first start selling on Amazon is the difference between Amazon Best Sellers Rank and organic ranking. Your BSR is how well the product ranks based on sales while the organic ranking is how well the product ranks for a given keyword. 

What is organic ranking on Amazon?

Organic ranking is where a product appears on Amazon’s search engine results pages (SERP) for a particular keyword. 

The product’s position on Amazon’s SERP has no bearing on the product’s current Amazon Best Sellers Rank. In fact, the products on the SERP are organized by what Amazon sees as the most relevant products for that keyword search.

For example, when we did a search for “marshmallow roasting sticks” on Amazon, this is what we saw on the SERP:

The products are organized by Amazon sponsored ads (also known as Amazon PPC) and organic ranking. 

The first three products that appear are those that paid to appear there. They purchased that ad space. 

The bottom three are those whose products ranked organically. We searched for “marshmallow roasting sticks”, and they were the products Amazon thought most closely matched what we said we were looking for.

However, just because a product ranks favorably on Amazon’s SERP doesn’t necessarily mean that it will have a good BSR as well.

The reason the top organic product may not have the best BSR as well is because Amazon sees the first product of its search results as a more keyword-relevant result when someone enters in the search term “marshmallow roasting sticks” — despite it not being the best seller of the bunch. This could be because the product has had better sales in the past, higher rates of conversion, or even better reviews.

Don’t mix up Amazon Best Sellers Rank with organic ranking!

Both of these values are important, but both have totally different functions. 

If you seek to create your own product on Amazon as a private label seller, then organic ranking is very important to you. The higher your product appears in the SERP, the more likely customers are going to click on it and purchase it.

Meanwhile, Amazon Best Sellers Rank is great for estimating the sales frequency of an individual product or an entire product category.

Where can I find the Amazon Best Sellers Rank for a product?

To find an item’s BSR, go to an Amazon.com product page (that’s the page you see when you click on a product after doing a search on Amazon). 

Next, scroll down to the product details portion of the page. If you’re on a mobile device, you may need to go to the product description block and click on it.

This is what you should see:

As you can see, the Amazon Best Sellers Rank for Patio, Lawn & Garden department is currently #358. Furthermore, it has a Best Sellers Rank of #1 in the Barbecue Forks sub-category.

This means that out of the hundreds of thousands of products in Amazon’s Patio, Lawn & Garden department, only 357 sell more than this particular item. Not too shabby!

What is a good Best Sellers Rank on Amazon?

Best Sellers Ranks are different for every category. So what one might consider a “good” Best Sellers Rank for Patio, Lawn & Garden a category with high sales volume, might not be as strong as a product in a category Appliances which has products with much slower sales.

The best way to pinpoint what you consider a good Best Sellers Rank is to consider the number of sales that you want your product to have each day (or week or month for that matter). Then, reverse engineer what your Best Sellers Rank for that total of sales would be.

For example, if I wanted to sell a Kitchen & Dining product that had 11 sales per day, I would need to find a product that had a Best Sellers Rank of 15,000 in that category, or an estimated 330 sales per month.

You can use the Jungle Scout Sales Estimator to help you determine what rank you should look for.

How to see the top-selling products by their Amazon Best Sellers Rank

If you want to see the top products on Amazon, all you have to do is go to the best selling products page and then click on a particular department. 

For example, here are the best selling Amazon products for the department Patio, Lawn & Garden:

Amazon Best Sellers Rank: Patio, Law & Garden best seller page

Everything you see here is selling extremely well on Amazon. You’ll also find that a lot of the products on the Amazon Best Sellers pages are disposable or consumable products; they’re items that necessitate high volume and/or frequent purchases, hence, more sales.. 

There’s a lot of seasonal stuff here as well. In the image above, you can see that there are Christmas lights and bug traps. Later in the year, it might be a completely different line-up of products, like Halloween decorations in the fall, sunglasses for the summer, or snow shovels in the winter.

It’s also worth noting that the top sellers on Amazon.com may not be the top sellers on other marketplaces like Amazon.co.uk or Amazon.es. 

How can I use Amazon Best Sellers Rank to estimate sales?

By far, the most powerful function of the Amazon Best Sellers Rank — other than bragging rights — is using the value to predict how often a product sells on Amazon.

Consider this: Let’s say we have a product that has a BSR of #1699. We know from our checking our own sales that a BSR of #1,699 translates to roughly 810 sales per month, as long as our Best Sellers Rank stays roughly around that same value.

But just a month ago, our average BSR was #3,000 for about 30 days and we only did 510 sales that month.

However, last fall, our BSR was #500 on average for 30 days and we did 1,980 sales that month.

What can we learn from this data?

For starters, we know that if we see another product on Amazon other than ours that has a Best Sellers Rank of #3,000, that product should sell 510 products per month, or close to it. Because that’s what our own product did when its rank was #3,000.

And a product currently ranking at #500? Probably 1,980 sales per month right?

How to determine what sort of products to sell on Amazon using BSR:

  1. Check the product’s Best Sellers Rank on Amazon using the methods described above..
  2. Estimate the average monthly sales for the product on Amazon to get an idea of how often the product sells. You can use the Sales Estimator.
  3. Calculate the cost to sell the item. This includes the cost of the product itself, any relevant fees, the cost to store the product if it takes a while to sell.

Let’s say you have an opportunity to buy these two different books for the same price each.

The first book is “Poor Charlie’s Almanack” by Charlie Munger. The book sells for $59.95 on Amazon. Currently, its Amazon Best Sellers Rank in the Books department is #1,942. A book that has a BSR of #1,942 has 540 sales per month. That’s almost a book every hour. This means if you purchase the book and list it on Amazon at the lowest available price, in an hour you will have a sale. Literally that fast!

The second book is the old Dungeons & Dragons module “The Tomb of Horrors”. This book sells for more on Amazon at $64.99. So we’d make more profit. But its BSR is #1,256,348. That means this book only sells 2-3 copies per month. If you buy and list this book, chances are you might not see a sale for a month or maybe even longer.

So which product sounds better? “Poor Charlie’s Almanack”, which is almost guaranteed a sale in its first 24 hours at $59.95, or “The Tomb of Horrors”, which may take months to sell on Amazon at a marginally higher profit?

Ultimately that’s your decision, but personally, I’d rather go with “Poor Charlie’s Almanack”!

  1. You are truly a wealth of information, Dave! Thank you so much! Is it possible to trouble you with some more information. As a week-old neewbie to ecommerce it can seriously overwhelming!


  2. Hello Jungle Scout! I am a new FBA seller on Amazon. I absolutely love Jungle Scout! Question…I plan to sign up for your service but I was trying the free estimator tool and I don’t see a category for books under the “Amazon Product Category.” Can you please let me know if I missed something? Thanks!

  3. I know Amazon updates their BSR hourly. Is there a specific time they update? Like on the hour/ half hour/ quarter hour? or is it random??


  4. Hi all,
    How do I find out how many copies have been sold of – “living unapologetically”
    does a book have to be registered?
    does it have to be provided to a library or a university in the state or the country of origin?
    thanks for your reply in advance
    Max – NSW Australia

    1. Hi Max,

      You can use the Jungle Scout Product Tracker tool to give you an idea of how many sales that book receives per day/month. Not sure what you mean by registered. Brand registered? And no, it does not need to be provided to a library or university to be sold on Amazon.

  5. Interested. Scope to be restricted up to Products manufactured within India and for sell within India, to begin with.
    Need guidance in identifying products having requisite data for product listing.

  6. Hi…
    Interesting stuff, but one thing notably missing is any reference to a total number of items on any particular ‘Best Sellers Rank’. Thus, it is not possible to get a comparitive measure of how well (or otherwise!) something is selling, at least relative to the -worst selling-! Example… a book I got for Christmas is rated as ~12,000,000…(!) certainly not a best seller. But I wonder… #12 million out of -how many-??? Do you know how many books -in total- may be on this list?
    Tnx, Sooty.

    1. Make sure your listing is optimized and that you have high quality photos. Focus on your PPC campaigns to get traffic to your listings.

  7. Hi,

    It was so crucial and knowledable for me as beginner. There was much to learn and clear. It was really helpful and your efforts are admirable.
    Thanks for this act

  8. Hi Dave,
    I see the Jungle Scout free estimator offers estimates for many different market places, but somehow i could not figure out for my life how to find the best seller rank for example in Mexico, can you help me with that?

    Thank you

  9. Hi dave i just found your article. So i decided to ask you some questions. I’m a beginner and a student i don’t have money for startup business but i want to make money on Amazon. I’m not so much about selling used items on Amazon either. Please Dave what are my options. Looking forward to hearing from you.

  10. Hi, is it possible with JungleScout to have the history of BSR, I want for example to get top BSR per category for a particular period, for example

    Top 10 products per category with best BSR
    For period : 2018-09-01 to 2018-09-30

    Thank you

    1. Hi,

      You can track specific products using product tracker and it will show you up to 6 months of data. You can also use rank tracker to track specific keywords over a particular time period.

  11. Hello Dave!

    Thanks for this amazing article. It really explains a lot as a new coming seller, like myself. QUESTION> Why is the BSR so significant when choosing a new product when the same similar private label products can be in a such a wide range?

    I look forward to your insights and thanks again for constantly sharing priceless and time saving information!


    1. Hi Nelson,

      While BSR is important, it is not the only thing you should be looking at. You are right, other products in that niche may have a really good BSR while others do not.

      If most products on the first page for the product in question all have good consistent BSR’s, then it may be a good opportunity to get into. If only 1 or 2 products are doing well then it may not be a good opportunity.

  12. I live in Jamaica and make handbags here as well. I am trying to figure out away around the bank account thing. Can you help?

  13. Hi,
    My name is Raul Toro, I am new in this FBA Amazon business, reading your articles and trying to get the BSR for the products, I dońt see it in Amazonś item description article. Do you need to have a professional Amazon account?

    1. Hi Raul! Thanks so much for reaching out about this, as you don’t need to have a professional Amazon account in order for your product to be given a Best Sellers Rank. Every product listed on Amazon’s platform will be given a BSR.

      However, there are times when an item is only given a BSR for its sub-category, and not for its parent category. For example, these ear buds have a BSR of 19, but it’s in the sub-category of ‘Earbud & In-Ear Headphones’. It doesn’t have a BSR in the parent category of Electronics.

      Not sure why some products aren’t given a parent-category BSR, but this happens a lot with electronics.

      I hope this answers your question. 🙂

    1. In terms of the Amazon’s Best Sellers Rank, Huzaifa, then yes. Though this was written with amazon.com in mind, the principles mentioned in the article can still be applied to products listed on amazon.ae. But, if you’re asking about whether or not Jungle Scout works in amazon.ae, not yet. Our data science team is working on expanding our compatibility to other marketplaces. Hope this answers your question.

  14. Hi,

    awesome article i need infos, do you if for example i want to sell international make up brands, is it to possible to buy from the wholesalers and sell in on amazon without permission of owner brands?


    1. Lou,

      Good question. So long as the wholesaler can issue the correct paperwork that Amazon needs, then yes. Always make sure it’s possible to sell a product before you purchase it. You don’t want to spend money on a product you can’t sell.

  15. But how do you search for a specific best seller? ie: Best Seller Kids Graphic Novels. Or Best Sellers Adult Scooter.

    1. Hi Emily,

      Good question. Typically, if you click on the category itself while in a product’s listing page, it will take you to the Top 50-100 sellers of that category or sub-category. Similarly, you can do a search on Google to bring up the same results.

  16. I have one question. Does Amazon allow us to see the best-seller ranking hourly in case I want to check on the product sales every hour?

  17. Stefan,

    Your article was informative and I’m interested. I have a product I will private label and supply. If I want to estimate the current sales of similar products on Amazon, which tool do you recommend? We are writing the business plan and are trying to determine the size of this eCommerce market. In our case– organic fertilizers for Home and Garden. Specifically Shrimp and Crab meal.

  18. In this paragraph, “The reason for this is because Amazon sees the first product as a more relevant result when someone enters in the search term “marshmallow roasting stick” despite it not being the best seller of the bunch. This could be because the product has had better sales in the past, higher rates of conversion, or even better reviews.”

    I wonder which product you are mentioning ?. First ranking product or the best seller ranking
