Would You Like to Have Your Own Calculator on Your Computer?

My team and I just created Publisher Rocket, a book idea validation software that not only uses the calculator above but also helps you to find book ideas that will sell.  It does this by finding popular search terms on both Amazon AND Google plus the following:

  • Tells you how many people per month type the keyword into Google
  • Tells you how many people per month type the keyword into Amazon (SUPER new feature)
  • Gives a score from 1-99 telling you how competitive a kindle keyword is
  • Tells you how much money other books are making
  • Gives you key data so as to beat those books and rank better

Plus this Kindle publishing software works on both MAC and PC.

KDP Rocket is available now for ONLY $97.  We are offering it as a one time fee, but soon it will become a subscription.  So lock in that lifetime access, one-time fee now!

How to find the Amazon Best Sellers Rank

You can find a particular ebook’s ranking number under the “Product Details” on any Kindle ebook’s product page:

Once you have this rank number, place it in

How to effectively use the KDP Calculator Numbers

Knowing the numbers is great, but knowing how to use them or when to use them can really take you to the next level.

The following are a couple of ways or situations in which the calculation can come in handy:

Check for Kindle Keywords or Categories

As you do your research to find effective keywords for your ebook’s sales page, this calculator can help to tell you if the results in a keyword search are profitable. You don’t want to target a Keyword phrase or Category that isn’t making sales.

Check Another Author’s Credibility

Sadly we operate in a self-publishing world where many marketers make false claims. I am sure we have all heard it… “yeah, I make 6 figures with my books every month” or something along those lines. If that is the case, go ahead and plug their ebook’s rank number into the plugin and see what comes up. Be careful though, the rank number changes frequently.

Kindle Sales Rank Goals

Just being able to see the target “books per day” can be a real difference maker and help an author set up their publishing goals. Instead of being a mythical number, you can now have a better understanding of what to expect and what is attainable.

    Hi Dave, it seems that the KDP calculator isn’t working. I can’t type anything into the text box. I am using the latest version of Chrome on a PC if that helps.

    • Dave Chesson on November 16, 2020 at 7:37 pm

      Could be a plugin on your browser blocking it. Try a different browser.

  2. Angeline Korimako on July 13, 2020 at 6:18 pm

    Hi, thanks for all this info! As a mainly YA fantasy writer, I found some generic useful information about book publishing- but nothing specific to genres. Which is fine. But- actually I have no idea why I’m writing this comment, sooo. . .

    • Dave Chesson on July 15, 2020 at 2:33 pm

      Well, hopefully you’ll find that many of the tactics here are applicable to all genres.

  3. Marianne Petersen on July 7, 2020 at 9:53 pm

    Yay – Now it makes sense how the calculator works! I kept thinking the number was how many books sold and the calculator divided it up to tell us how many per day it took to get to that number. But now I know what the number we copy and past is. Now I know thus now I like it even more. Thanks.

  4. Marianne Petersen on July 7, 2020 at 9:37 pm

    Great help you’ve given me thus far having started Published Rocket a few days ago.
    You may have answered this question already but I’m just gonna ask here. I can’t but ask how you come up with the number for the calculator. Do you work with a certain number to divide the rank number up with? What if it’s a one-year book verses a 4-year book? I can’t help but wonder as I get my brain to figure out how all your wonderful helpful info works.

    • Dave Chesson on July 10, 2020 at 2:17 am

      I see you found the answer 🙂

  5. Marianne Petersen on July 7, 2020 at 1:52 pm

    Where to even begin but … THANK YOU! This calculator is a little piece of gold.
    I found you about a week ago via HopeWriters, getting me to check out what you offer vs other sources. What you have put together is perfect for what I need!
    I’ve had Publisher Rocket a few days now, prepping up to change my keywords (I laugh now at what I put in a year or so ago, totally understanding now why no one is finding my book.) I’m now taking the time to watch more of your instructions and info on this-and-thats.
    God knew juuuuuuust what I needed.

    • Dave Chesson on July 10, 2020 at 2:15 am

      Super cool and glad you found them. Enjoy and best of luck!

  6. Eliana Salvi on April 16, 2020 at 8:00 am

    Hi Dave! Is the ranking and calculator working only for US products? What about or other single countries? What shall we use? Thanks

    • Dave Chesson on April 16, 2020 at 4:28 pm

      Yeah, currently only for the US. Not sure of what else is out there.

  7. Kzainshah on March 10, 2020 at 7:50 am

    hey, this shows me 44 books sell in a day but it did not selling why is
    like that?

    • Dave Chesson on March 16, 2020 at 3:25 pm

      If a book is listed as KU, download of a KU book can affect the ABSR.

      • Kzainshah on March 17, 2020 at 11:16 am

        Thanks For Reply, I Don”t Want to listed as KU

  8. Vago. on January 14, 2020 at 8:40 pm

    Hello, Dave:First of all, thank you for your amazing blog. It has been very enlightening for me. But I have a question about this topic. When you talk about the Amazon Best Seller Rank, does it take in count the country you are from? I mean, if my ideal market is in Mexico, should I do my research on Amazon MX or Amazon US? Does it makes a difference?

  9. Lisa Beckfield on December 8, 2019 at 11:02 am

    is this calculator only works with US Amazon? I’m looking for Amazon UK or Canada or all the available KDP countries

    • Dave Chesson on December 8, 2019 at 8:29 pm

      Just the US.

  10. Scott Mcdowell on November 9, 2019 at 7:10 am

    Will there be a audio book sales option in the future?

  11. Pork Rynes on October 25, 2019 at 10:53 pm

    HI Dave, I transferred the KP Keyword search and all the New`s Letters we received from you and put them in one folder. But when I click on the Keyword search It is not there. Any ideas? Thanks, Bruce

    • Dave Chesson on October 29, 2019 at 1:50 pm

      Hi Pork. Not sure what you mean. Are you saying you saved some things on your computer, but when you go to look for it, it is not on your computer?

  12. Marcia Ledford on October 3, 2019 at 1:00 pm

    I just bought this software and can tell it is going to be really helpful. Gentle suggestion, put the calculator in the software`s nav bar for quick access from any page we are on. The search box does not bring the Kindle Calculator up, so it is hard to find. Dave, I think what you are doing to help self-publishers is an important contribution to what is often dizzying for the first timer. thx a bunch. I really like your video on setting up a publishing company and recommend it to our tribe.

    • Dave Chesson on October 3, 2019 at 10:11 pm

      That is awesome and glad you like it, as well as the video. As for putting the calculator in it, I’ll see what I can do. I try my best to keep Rocket streamlined because if I put too much on it, it could come across as daunting. But I’ll give it a good thought!

  13. Jacob on September 15, 2019 at 1:13 pm

    Hey Dave. Just bought KDP Rocket and have been diving into your wealth of info and resources. KUDOS, RESPECT and THANKS for all you do to help publishers and marketers get a more informed foothold on the business. You and your team change lives and inspire. Couple of questions: Looking at this thread, it seems not much has been happening for quite a while. 1) When will you have a KDP Rocket expansion that includes other markets–specifically for my intereststs, Amazon Japan? (I live there). I saw a few of your comment replies saying other markets (like Italy) are ‘on the way’, so I was wondering if you had any more specific timeline estimates yet, now that we are halfway through 2019. . 2) what happened the podcast? I am now catching up with it from zero, but it seems to have ended about a year ago? Just wondering what`s the scoop. anyway, again, you are heroic for what you have built and what you do!

    • Dave Chesson on September 16, 2019 at 1:50 am

      Thanks and that totally means a lot to read. As for your first question, we are just finishing up on the German beta and hopefully should be adding Germany for free in the next couple of weeks. As for your second, I actually put it on pause because we came out with Rocket 2.0 and I needed to spend more time on some new features I wanted to add – really awesome stuff coming soon. Once that, and many of the markets have been added, I’ll probably jump back in the podcast production 🙂

      • Jacob on September 16, 2019 at 1:57 am

        Thanks much for the quick reply, Dave! So as far as the Japan market (specifically)…?

        • Dave Chesson on September 16, 2019 at 11:02 am

          No specific date on that one…the key is we aren’t just throwing in the Amazon information and then just making up the analysis or reusing another market`s analysis. We have to study each market, make deals with publishing companies so that we get continual data to analyze and compare to Amazon`s market (and improve accuracy), and build out full category systems – which others that claim to have the other markets do not do. We require accuracy and systems to show effectiveness.

          • Jacob on September 16, 2019 at 11:08 am

            Gotcha! Thanks for the clarification!

  14. Blake on August 14, 2019 at 5:04 pm

    Outstanding! I’m publishing my first book in October, and this information is a game-changer. Thank you for sharing what you’ve learned.

  15. Shady Johnson on February 13, 2019 at 9:29 am

    amazing post Dave….great to know about the Calculator…thank you for sharing!

  16. FilmyGram on February 8, 2019 at 9:39 am

    Hey Dave loved the calculator.
    Thanks for providing the details.
    Please keep sharing it!

  17. Samantha Silverstein on February 6, 2019 at 7:13 pm

    Hi.I did some reserch on Amazon for my book on how to write characters who are disabled. I did not find anything on the market. How do make my idea profitable when I have little to compeat with?

    • Dave Chesson on February 7, 2019 at 1:43 am

      If you have KDP Rocket then you’ll be able to look and see if anybody on amazon is actually looking for that kind of book. If nobody is searching for that kind of book, but you still believe there are people that need this kind of book, then proactively getting it in front of them through Amazon ads is your best bet.

  18. Luisa Scognamiglio on January 18, 2019 at 10:41 am

    Hi Dave!, your fantastic KDP ROCKET has the ability to interface with other applications using the API?
    Thank you

  19. emmarose101 on January 17, 2019 at 11:27 am

    Hi Dave, Just wondering if there is a version for available?

    • Dave Chesson on January 17, 2019 at 4:53 pm

      Not yet but we’re working on it.

      • emmarose101 on January 18, 2019 at 4:31 pm

        Thanks! Do you know roughly how well it might translate at least? My publisher and the calculator are disagreeing by around 1000 copies at the moment!

        • Dave Chesson on January 19, 2019 at 1:39 pm

          I cannot say for sure. But it would be pretty different.

  20. Luisa Scognamiglio on January 3, 2019 at 2:08 pm

    Hi Dave, I just bought KDSPY and I congratulate you, EXCELLENT TOOL!
    Can KDSPY also be used in AMAZON.IT?
    And also, the number of copies sold, inserting the kindle-BSR in AMAZON SALES RANK CALCULATOR is also real for

    • Dave Chesson on January 3, 2019 at 7:43 pm

      Hi, do you mean KDP Rocket? That is teh software I created – KD Spy was made by someone else. If you’re talking about Rocket, then it will be soon. We’re adding each market systematically and ours will actually be using‘s ABSR calculations – something we’ve been working and developing for over a year now.

      • Luisa Scognamiglio on January 3, 2019 at 8:14 pm

        I’m sorry Dave, KDPROCKET !, when will the version available on be available?
        Also, when will AMAZON SALES RANK CALCULATOR be available for
        Thanks Dave!

        • Dave Chesson on January 3, 2019 at 9:13 pm

          Not sure about Italy – it dpeends on how smoothly other markets come online. As for the Calculator – I’m not sure. I’ll probably finish all of the markets on Rocket and have another project my programmers are working on before turning to ABSR Calculator for the other markets.

          • Luisa Scognamiglio on January 3, 2019 at 9:22 pm

            OK, tankyou …. ABSR Calculator does not work for

          • Dave Chesson on January 3, 2019 at 9:36 pm

            Not yet.

  21. wirdmonger on December 10, 2018 at 8:32 am

    Ugh do not you just hate it when you hit POST and immediately see typos? I meant ‘ranked’.

  22. wirdmonger on December 10, 2018 at 8:31 am

    I have a book raked at 7000 in books on Amazon right now. It is averaging between 25 – 35 sales a day for the last 10 days. I plugged 7k into the tool and it suggests 17 books a day. So I think it is estimating a little light. I still love this tool though. Perhaps it is a seasonal effect – I will try again later.

  23. Mary Elledge on November 10, 2018 at 4:02 am

    I got the KDP Rocket 2 days ago and I love it. I am not exactly a young woman and I was spending a lot of time on researching for everything. KDP Rocket has just taken care of all of that for me. I have been going through the tutorials and it is all just so wonderful to use and I just love it. I am also going through your course here and it is a blessing to me. Thank you so much for everything. Also, I sent you a message in my email and you answered so quickly. This is awesome for this old woman.

    • Dave Chesson on November 10, 2018 at 9:54 pm

      Wow! Thanks Mary. This totally made my day to read. That is exactly what I built it for and I’m so glad you found it. Serious – big smile on my face 🙂

  24. Grazina Ajana Szewczyk on October 5, 2018 at 4:45 am

    I tried to copy/paste the number but it doesn’t work, even when there are no commas. When type It is OK. I wanted to check a few books so copy/paste is much easier than retyping (and more accurate). Any suggestions?

    • Dave Chesson on October 5, 2018 at 3:57 pm

      Hmmm, there shouldn’t be a problem as long as there is not comma. Is it not entering the number at all or just not calculating?

  25. Joanie on August 8, 2018 at 5:42 pm

    I checked this using my book`s rankings and my publisher`s data and It is extremely accurate!

    • Dave Chesson on August 8, 2018 at 10:00 pm

      Awesome – yeah, we’re always working to improve it and keep it up to date.

  26. Vasilymp Mendoza Pérez on June 27, 2018 at 2:51 pm

  27. Alessandro Cosimetti on April 29, 2018 at 12:41 pm

    Tha calculator now doesn’t work. Can you verified please?

    • Dave Chesson on April 30, 2018 at 2:42 pm

      It works – just make sure to follow the instructions and do not have a comma in it

  28. Tuan Anh Chu on April 22, 2018 at 10:51 am

    Please, could someone give me some advice about Kindle publishing: Could I publish different category ebooks under different author`s name(pen name) in 1 account ? THANKS!

    • Dave Chesson on April 22, 2018 at 9:41 pm


  29. tom on April 5, 2018 at 5:41 pm

    Is this tool working up to date? Do you use only the kindle best seller rank for both the kindle button and also when clicking the books button? Or, do you need to use the book seller rank when calculating for “books”.thanks

    • Dave Chesson on April 5, 2018 at 8:02 pm

      Yup – still working and always kept up to date. If you get the book`s ABSR, then click book. If you get the Kindle ABSR, then click Kindle and put the number in.

      • tom on April 5, 2018 at 8:21 pm

        OK thanks for the speedy reply!

        • Dave Chesson on April 6, 2018 at 2:35 am

          You bet!

  30. Jennifer Lawson on February 19, 2018 at 3:25 am

    Hi! I’m curious if you plug in the top Best Seller rank number? Or the number for a specific category? I know that specific categories usually get better ranks, correct?

    • Dave Chesson on February 19, 2018 at 5:02 am

      It is the top Best Seller Rank like the picture above shows.

  31. S. H. on February 1, 2018 at 3:40 pm

    Hi, Dave.
    My KPD author rank averaged 3000. I put 4000 in the calculator, just to be on the safe side. The calculator`s estimated number of sales per day is actually about the same as sales per week that my publisher is reporting to me. Can this be because my book is on KU, and that is boosting the ranking, though I am not selling quite that many books per day?

    • Dave Chesson on February 1, 2018 at 11:16 pm

      Hi S.H. The calculator isnt for ‘author rank’. It is for the Amazon Best Seller Rank. The author rank is a completely different calculation. I hope that helps .

      • S. H. on February 2, 2018 at 1:40 pm

        Sorry, Dave. I mistyped. I am using the Best Seller Rank. This week I averaged 3000 all week but my sales were reported as only 65 books total for the week.

        • Dave Chesson on February 2, 2018 at 1:43 pm

          Ah, okay. There are two things that affect your ABSR. Purchases, and KU/downloads. The calculator cannot depict which one was which (no way to tell that), so it just assumes all was made through purchases. I hope that helps.

    So has the calculator stopped working?

    • Dave Chesson on December 5, 2017 at 5:54 pm

      No…just checked it. It’s working.

  34. Janie Ellington on September 27, 2017 at 9:17 am

    Hi Dave,

    Awesome! It’s gonna help me to step further in my book selling strategy. I’ll test it out for few days to learn about it more. I am using for my products sales estimates. Its a nice sales estimator but doesn’t seem like working on books. So, I’m definitely going to give it a try. I’ll be back when needed help. Thanks

  35. Marie Petroff on September 5, 2017 at 6:46 pm

    How do the Kindle Books and Books results relate?

    If I enter an ABSR of 1994, I receive 65 book sales and 90 Kindle sales. Do the two results represent total sales? I don’t want to overstate competitor sales in potential market size for my publication submissions.

  36. Marie Petroff on September 4, 2017 at 10:34 pm


  37. Vicente Morales on July 21, 2017 at 6:10 pm

    Great tool. Is the Kindle Best Seller Rank affected at all by KU? If an author’s KBS rank gives a figure of 15 books per day in the calculator, and that book is also part of KU, does that mean the 15 sales per day are separate from KU borrows/page reads? Or is the KU stuff already factored into the Best Seller Rank?


  38. Michal on June 11, 2017 at 8:20 am

    KU grossly skews your ranks.
    It only shows how much importance Amazon puts into pages read.

  39. Paul Mannering on May 2, 2017 at 6:13 pm

    Hi Dave. I gotta say I’m still struggling with the logic of this. I’m keen to understand how it works – so I can moderate my expectations accordingly.

    If at any given time your calculator estimates that I am selling X books due to it’s current (at that particular time) sales rank – then is that an accurate (within tolerance) estimate of the number of books that should be sold during a 24 hour day – provided that the sales rank doesn’t change dramatically during that 24 hour period?

    It would seem that if the calculator says I’m selling (for example) 10 books a day – then 8 hours later (for example) it says I’m selling 8 books a day – I would expect that the probability is during that 24 hour period – I sold somewhere around 8-10 books.

    Allowing for the 2 hourly updates of the ABSR it would seem that a random check of my ABSR during a 24 hour period would show a massive variance in ranking through out that period to balance out the high daily ranking.

    I have seen the tables provided by indie authors where they equate their sales rank to their sales figures and that doesn’t match my experience either.

    My only source of truth at the moment is the quarterly royalty statement from my publisher which lists the number of ebook copies sold in total between the two statement dates.

    If you could create an app that automatically checks a books ABSR every 2 hours and records that data – I’d pay for it 🙂

  40. Alison Page on February 22, 2017 at 2:10 pm

    Hmm, I put my ranking in, 16300, and the calculator reckons 4 per day. The book’s actually sold 3 copies in a week. So not an accurate tool at all it would appear.

    • Dave Chesson on February 22, 2017 at 6:59 pm

      Hi Alison, actually, come back tomorrow and let me know…because the Amazon Best Seller Rank is based on today’s metrics whereas your sales only show up to yesterdays. And there is NO WAY you have a 16300 ABSR but have only sold 3 copies this month.

      Here are also a couple of reasons why that may be off:
      1. Did you get the right number? The is the Amazon Best Seller Rank…not the rank for a category (See picture above)
      2. ABSR is also affected by Kindle Select downloads and KU pages read.

      • Alison Page on February 23, 2017 at 1:26 pm

        Hi Dave, thanks for your reply.

        I still don’t get it. The ranking today is showing as 53,000 and it’s definitely the right figure that I’m using. The calcuator shows 5 book sales a day – I wish! So far it’s sold 3, total.

    Not sure if it’s just me but the button doesn’t seem to be doing anything. No commas in my number…

    • Dave Chesson on November 10, 2016 at 1:10 pm

      Yeah, I’m actually in the process of updating the numbers and adding another feature to it…so you caught me while I was/am working on the code. Should be ready and shinny by tomorrow. I’m always working to make this stay up-to-date and current with the changes in Amazon.

  44. Charles Davis on September 15, 2016 at 10:38 pm

    Kindle volume versus ranking seems strongly dependent on price. My wife’s Kindle book, at $17.99 on the 35% royalty deal, can get in the 15,000s with sales of two or three. My book, at $9.99, on the 70% royalty, will get to 15000 with about 6 sales. Dave calculator say 15000 means sales of 14 book.
    Dave needs to add a price inputs, and possibly a selection of royalty deal.
    Further, estimating print books from kindles is fraught with peril. First, price is all important. Second, format matters. A picture oriented book will do relatively less well on Kindle. My mostly text paperback is roughly 1.5 print books at $16.74 to each kindle book at $9,99. My wife’s book is a $32 cookbook and she sells 3:1 more print than Kindle.

    • Dave Chesson on September 15, 2016 at 10:48 pm

      Hi Charles. Great observations, but the Amazon Best Seller Rank does not account for the chosen price of a book (except for free – they get their own Rank structure). What you might be seeing is the time independent structure of the ABSR. ABSR does not work in an 24 hour metric of “how many books were sold within the one day period.” Instead it tracks the overall sales over time and weighs the most recent sales strongly.

      Example: Say your book hasn’t sold at all for the past 3 weeks. Then, all of a sudden, within a 2 hour period (ABSR updates every 2 hours mostly) 5 books are sold. Your ABSR will not improve as much as say….someone who sold an average of 1 book per day, and then all of a sudden sells 5 the next day. That person will have a much better ABSR than yours.

      The bummer part about my free calculator above is that it doesn’t track books over time and thus doesn’t account for previous sales. Instead, it gives an instantaneous value to help give people instant results. Our value was actually calculated over 1000’s of data points and thus created the average you see. Statistics…gotta love it.

      • Jaime D. Buckley on November 1, 2016 at 3:58 pm

        Hey Dave?

        I’m loving this tool for research but I’m curious if you could expound on the Rank Structure for FREE books, as i have 2 perma-free books to generate traffic??

        • Dave Chesson on November 2, 2016 at 2:06 am

          The rank structure for free books is different from the Kindle one and the Book one as well – all three are different. I can’t say for sure what that is because the free one is ALWAYS in flux. Unlike Kindle and Book ranks, which only add new products every day, the free one fluctuates with books on and off at time. Therefore, it’s near impossible for anyone to track due to the large beta.

    • yogizoli on February 5, 2018 at 4:07 pm

      wow, it’s very thoughtful! Yes, indeed, price and royalty would be great! Also, this shows my book over 600K in Amazon Best Seller list, should not make any money – however it makes. Is this calculator outdated? Thanks

  45. Ayodeji Awosika on July 14, 2016 at 9:46 pm

    Hey Dave,

    LOVE the revamped calculator. Thanks for continuing to provide insanely detailed and helpful tips with us. Too bad your emails keep going into my promotions folder. I drag them out and everything.


    Keep up the good work.

    • kindlepreneur on July 15, 2016 at 5:46 pm

      Hey Ayodeji, that’s a bummer my emails keep doing that. I’ve thought about switching to a plain text version so as to have less chance of going to promotional boxes…but then I lose uniqueness in the look and style. Anyways, thanks for the love and we’ll keep at it.

  46. ReadSpeeder on July 14, 2016 at 2:39 pm

    Just some feedback. I entered my current rank: 25,897 and got a per day number of 11. But my real sales were 6 yesterday and an average of 5 in the last 7 days. It seems like the calculator might need some more tweaking.

    • kindlepreneur on July 14, 2016 at 7:29 pm

      HI ReadSpeeder. Was that for ebook or book? Also, what are your KENP pages read/KU numbers? And, do understand that the ABSR is updated every 2 hours – not 24 hours. Your six sales yesterday would have been a part of yesterday’s ABSR number.

      The truth is, the ABSR is a time derivative equation that takes into account all sales and downloads in 24 hour period and gets updated every 2 hours. It includes KENP pages read as well. These are things that an initial number can’t take into account for pure accuracy – Instead we created the Kindle Best Seller Calculator to help give you a better indication of what other people’s books are doing so that you can validate future book ideas, check people’s claims and understand trends in the book sales market. I hope it helps.

      • Olesya Kalinina on August 9, 2016 at 12:14 pm

        Same situation with my book. It is a cookbook and the BSR was changing from 30k to 22k and now to 26k during the last 24 hours. In fact I only made 5 sales. I’ve been checking on your calculator before, and it seems it is not working correctly for cookbooks. And as for KENP – I’ve got 145 pages read yesterday.

        • Dave Chesson on August 9, 2016 at 12:20 pm

          ABSR updates every two hours, so you’ll see fluctuations. Also, your reported books will occur the next day, so compare what you see in KDP tomorrow to the numbers you see on ABSR of today. Also, ABSR is a time derivative number. It’s actually based on sales over the past couple of days….actually more of a logarithmic scale. So, to help give instant numbers, we even the playing field to create something that’s middle ground. But, you’ll also find that Author Earnings and our numbers are about dead on.

    • Creldarix on July 28, 2017 at 9:12 am

      I agree, I entered my numbers and I think it’s not covering all the bases either. I think time on the market is a factor, reviews, and who knows what other mystical things.

    Hi, thanks for this tool. I guess it relates only to the .com store. In local stores, the sales rankings display different numbers. Any idea how to calculate that? Thank you!

    • kindlepreneur on December 13, 2015 at 2:15 pm

      Yeah, sadly, that is true. The numbers used to compile the different equations for the plugin were based on the US market.

  54. Troy on November 5, 2015 at 3:03 pm

    Love this tool, but your estimate appears to be about double the reality for rankings between 50k and 70k. The tool calculated 4 sales at a 58k rank but my actuals (according to my publisher) were 2. Any thoughts?

    • kindlepreneur on November 5, 2015 at 3:36 pm

      Hey Troy, simply put, the calculation for Best Seller rank is not linear and factors in previous sales volume over a period of 24 – 48 hours. Since my program doesn’t track your sales over a period of time, but instead gives a quick snapshot based off of a one time projection, I added in buffer (based on hundred’s of data points from other authors) so as to best represent that ebbs and flows of other author’s books and give a good “estimation.”

      • Troy on November 5, 2015 at 4:23 pm

        Aha. So am I understanding correctly that significant historical sales would push the current ranking up? That would explain why my sales at a ranking of 50k are about half. It’s a great tool. Thanks for posting this.

        • kindlepreneur on November 5, 2015 at 4:33 pm

          Yup. That’s the idea. Kind of makes sense when you think about it. Amazon wants the successful books to have a higher rank and not just a book that happens to have all their sales made in a matter of one hour. Thanks! It was quite a challenge, but I do have another free tool coming out soon. Its in beta testing but will help people design better looking book summaries using the allowing CSS. It will be WYSIWYG form, so no need to know how to program CSS and tags into your writing.

  61. Richard Livitski on August 29, 2015 at 4:17 pm

    This is a great tool…thanks!

    I’m curious though…

    In your example showing How To Find The Amazon Best Sellers
    Ranking it shows a ranking of #38,121 which is what you highlighted.

    Just below that it shows rankings of #23, #28 and #30 in
    different categories at Kindle. Typing in 23, 28 and 30 shows MUCH higher sales
    daily than 38,121.

    Should I total all the daily sales of these ranking numbers
    to get an accurate daily sales number? Or is the daily sales from the 38,121 ranking
    the only one that I should be considering?


    • kindlepreneur on August 29, 2015 at 4:22 pm

      Hey Richard! The first number of #38,121 was the Amazon Best Seller Rank. This is a comparison of ALL ebooks. The numbers below that were Category Ranks. That number compairs all books list in that particular category. The calculator above has been calibrated to help you with the Amazon Best Seller Rank. I hope that helps!

  62. Christina Succurro on August 27, 2015 at 9:33 pm

    is this for real? I’m having copyright issues and looking to find out if the scammer has sold any books

    • kindlepreneur on August 27, 2015 at 10:29 pm

      Yup…it will help with that because it is based on Amazon’s Best Seller Rank which ranks books based on their sales numbers. So, if they are ranked 80,000, then they have been selling enough books recently so as to beat over 1 million others books out there. Is the calculator completely accurate? No, but its close.

      • Christina Succurro on August 28, 2015 at 7:57 pm

        on the ranking is in the 600k’s but on it’s in the 8k’s. The .com version is telling me this book has sold less than a copy per day, once i input the .ca digit it tells me 15 per day. Which is accurate and what is the difference?

        • kindlepreneur on August 28, 2015 at 8:09 pm

          It’s based on .Com and not .ca. The difference is that the rankings are dependant on all the other books in that industry. In “CA” it might only take 12 sales a day to go into 15,000s. But in .com because there are more, it will take something like 22 sales per day. So basically, it depends on what is happening in that market, and how much competition exists in that market.

  63. Syzygy999 on August 25, 2015 at 5:07 pm

    I entered a sales rank, clicked the button, and nothing happened. Is this a browser issue perhaps (I’m using Opera)? Or is the app no longer working?

    EDIT: Never mind. It worked when I removed the comma from the sales rank.

    • kindlepreneur on August 25, 2015 at 11:01 pm

      Haha….yuyp, was about to say that. I’ll edit the page to ensure that shows up for people. I am also about to shoot a video talking about the program and a more in depth analysis of how the calculation really works. Hope you enjoyed it!

  68. Michal on June 15, 2015 at 10:51 am

    3 things:
    -it won’t be reliable after a big promo; 5 days ago my book sold 80 copies and about 4 a day since that; the calculator shows 14 copies a day
    -it really shows sales+borrows, because both affect the rank
    -I think it overestimates just a tiny bit (see the screen, calc said it’s 14 a day)

    • Kindlepreneur on June 15, 2015 at 2:34 pm

      Sadly, the A7 algorithm that calculates the Amazon Best Seller Rank takes into consideration sales over time with a logarithmic scale. Therefore, the perfect calculation would have to consider the highs and lows over time….which would require the tracking of the information for a certain period of time. This plugin will serve as a go-no-go criterion for keyword and category selection.

      • Michal on July 13, 2015 at 7:11 am

        No tool is perfect without knowing the exact Amazon’s algorithm. For the purpose you’ve designed it, this is the best tool on the Internet.
