Calculating Amazon FBA Fees – Know Your Numbers and Make Better Buying Decisions

Know Your Numbers - FeesA while back I saw a super scary video. It was truly horrifying. I still have nightmares when I think about it for too long.

I showed a short clip of this video to my wife. She actually screamed at the TV: “Nooooooo!!!!!!!!” She was just as terrified as I was.

In this video people were walking the aisles of a big box retail store, scanning toys with the Amazon app. Not the Amazon Seller app. The Amazon app. The one you use to buy merchandise from Amazon. These people were looking up toys on Amazon, comparing the price on the retail store shelf, and loading up a shopping cart if the price was even the slightest bit higher on Amazon. They intended to buy this shopping cart full of toys and sell them on Amazon.

As if this scenario weren’t gruesome enough, these people were actually encouraging their viewers to go out and do the same thing. They exuberantly proclaimed that anyone can sell on Amazon, see, look, there’s merchandise everywhere that sells higher on Amazon than in stores. You, too, should go out and buy toys by the shopping cart load, and just send them in to Amazon and wait for your paycheck.

At this point you might be ready to ask me a few questions. “How is this scene any different than what you do in your Amazon FBA business every day? Don’t you use retail arbitrage as one of your strategies for finding FBA inventory? Isn’t that what these folks are doing – and showing others how to do?”

The key difference boils down to one simple factor: I never buy an item for resale without knowing the Amazon FBA fees for that item first. If someone were to actually follow the methods these people were using in this Amazon FBA horror movie, they would be hit with fees they hadn’t calculated beforehand and suffer financial loss.

2631823For anyone who wants to make a profit running an FBA business, you have to know your numbers. You have to know all of your expenses, including inbound shipping, taxes where applicable, prep fees, materials, and the cost of any subscriptions or services you buy. You also have to have a good handle on the FBA fees that apply to any items you intend to have Amazon fulfill for you.

If you aren’t aware, the name of this blog is Full-Time FBA. About 99% of our Amazon business is through the FBA (Fulfillment By Amazon) program. We do choose to Merchant Fulfill items on occasion (check out our YouTube video where we discuss those occasions), but overall we prefer to stick with having Amazon fulfill our inventory when a customer buys it (see also our blog post “Overcoming Your Fear of Selling via FBA versus Merchant Fulfilled or eBay”).

There are 4 easy ways you can calculate the potential Amazon FBA fees before you buy an inventory item. We’ve listed below two options for calculating fees on your smart phone and two for calculating fees on a web browser:

  1. AZ Seller app screen shotAmazon Seller app – FREE

The Amazon Seller app is free and allows you to scan items either by barcode or using Amazon Flow (the camera of your phone recognizes an item’s image and matches it with the product in the Amazon catalog). The Amazon Seller app allows you to see the fees for an item if you sell it Merchant Fulfilled or through FBA. It allows you to adjust your selling price, your inbound shipping cost, and the cost of purchase. It then subtracts the fees and your cost of purchases, giving you your estimated net proceeds. (See this blog post for more pros and cons on the Amazon Seller app.)

  1. Photo Apr 15, 10 23 15 PMThird party scanning app, like Scoutify, Profit Bandit, or ScanPower – PAID

Similar to the Amazon Seller app, third party scanning apps allow you to scan items by barcode or enter a text search for the item. Third party apps also allow you to adjust selling price, inbound shipping, and cost of purchase before you subtract out the FBA fees and see your estimated net proceeds. We personally use Scoutify most often when sourcing, with Profit Bandit being our back-up on occasion. (For more info on third party scanning apps, check out our blog post about why we use Scoutify.)

  1. FBA CalculatorThe FBA Calculator website – FREE

If you are doing product research on a web browser, Amazon Seller Central has an FBA revenue calculator where you can enter the ASIN, UPC, or product name of an item and do the same calculations as above to find out your potential fees and potential profit. We highly recommend creating a bookmark for the revenue calculator so you can easily reference it when making online purchases, determining prices for your inventory during the listing process, or repricing your inventory after it’s at the warehouse. We’ve also created a quick link for the calculator:

To see the FBA revenue calculator in action, I’ve created a screen capture video explaining how it works.

  1. Scanalyze 1Google Chrome extensions, like Scanalyze  – PAID

Another easy way to see FBA fees when doing online arbitrage or product research is by using Google Chrome extensions that show the fees right on the Amazon product page. We use Scanalyze (available through the Cyber Monkey Deals website) and love it. You simply click the “Scanalyze” button and the fee calculator pops up at the bottom of your screen.

Hopefully you’re equipped now to calculate your fees and know up front what your profit potential is before you buy inventory to send to Amazon. Please don’t become another victim in a scary movie! You can make good choices. You can build a profitable Amazon FBA business because you know your numbers.

  1. Where is the video that made you so scared? I want to see it

    • Rebecca Smotherman Rebecca Smotherman

      We intentionally didn’t include a link because we don’t want to turn this post into a way to publicly shame someone.

  2. Humm, nice clickbait guys! Scaryvideo… ?

    • Rebecca Smotherman Rebecca Smotherman

      I’m not sure what you’re referring to??

      • When you advertise (through email or just through article title) to people there’s a scary video you are immediately creating anticipation, and then when it’s not there they feel like they didn’t get what they came for.

        I’m 99% sure I’ve seen the video you’re referring to, and yea it’s terrible, I stopped taking them seriously when I saw they left that video up for so long. But if you wanted to reference it in front of your audience without showing them or getting a backlash it needed to be a bit part.

  3. shame on you guys

    • Rebecca Smotherman Rebecca Smotherman

      Do you care to elaborate why you would leave this comment on an article designed to help sellers calculate their FBA fees? I don’t understand what we have to be ashamed of in providing free content on our blog and through YouTube videos giving detailed instructions about how to use an FBA calculator.

      • I think because the link was supposed to bring us to a scary video about retail arbitrage and instead we were brought here…. bad link?

  4. Very informative, as usual. Keep up the good work.

  5. Rebecca,

    Great article. When read the information will help folks save big time. For new sellers there is way too much confusion on how to make the right profit from what you choose to sell and what to expect for profit when its sold.

  6. Meredith Puff Hofmannmere

    I have a question. When looking for retail arbitrage products for FBA, couldn’t we only buy items that we know could sell for three times the amount, instead of figuring out the exact fees?

    • This is usually a good strategy when you are first starting out, but for those who want to make good money over the long term selling on Amazon, you’ll need to learn to find items where you’re comfortable making an ROI of 50%, 40%, 30% and sometimes even 20%. Some see that as risky, and it can be… but even a 20% ROI is better than the stock market.

  7. If I don’t happen to have my scanner/phone available for whatever reason, is there a general “cost estimate” rule? For instance, if I find an item for $5 that I know (for whatever reason) that I can sell for double or triple, is there a pretty standard percentage to calculate against margins in order to make the buy decision?

    • If you don’t have your scanner then how would you know what the current sales prices are? You need to compare with the current prices so you don’t make a mistake… don’t assume it’s selling for more on Amazon, you need to know for sure.

  8. Thanks for the article; it was very informative! I didn’t have to see a video to know it was scary!

  9. As usual a very informative article. Anyone who sells thru Amazon would be wise Amazon to know all the fees in order to know their potential profit before buying the item.
    As to the controversy over the video I think in the future to avoid this type of feedback don’t use a url like you did in this case with “Scaryvideo” in it. This seems to indicate the url will link to a video even though the email had no indication that the video was a part of your article. Just my suggestion. Again thanks for all you do for Amazon sellers.

  10. Really! Is is that big of a deal the video wasn’t here? What ever happened to imagination? Great article guys as usual! And FREE advice to boot. Thanks!

    • Here’s analogy for you – How would you feel when you bought a product for specific use because it had one of features you really wanted but haven’t got that feature it promised? Normally, Amazon customers would return it in such case giving it “Not as described” as a reason of return.

  11. Where is the video to learn lesson from? I came to check if it’s the video I have in mind to confirm my suspicions and possibly avoid those who don’t know what they are talking about. Instead I saw an article about knowing my numbers before doing business which is something I always do…

    For anyone who read our newsletter and came to this blog post hoping to see the video we refer to, I will repeat what I commented above: We intentionally did not include the link to the video because we do not want to publicly shame someone. Honestly, I don’t even know where the video link is at this point, and there is nothing more to be learned from watching the video than from the short description we gave above.

    For anyone who feels that you were deceived by our newsletter as to what the content of this blog post would be, here is a quote from the newsletter that specifically says what the content of the blog post is: “In today’s blog post, I’ll share with you what we saw these resellers doing, what went terribly wrong, and how you don’t have to make the same mistakes they did.” This is exactly what this blog post covers. We were not attempting to deceive anyone.

    For anyone who considered the newsletter to be click bait, please understand that the definition of click bait is deceiving people into clicking on a link in order to earn advertising revenue from those clicks. We do not advertise on our blog and receive ZERO compensation when someone clicks on a link to come to our blog. If you clicked a link thinking it would be a video and you came to this blog post instead, I sincerely apologize for the 5 seconds of your time that it takes to close the tab and move on with your day.

    We send out a weekly newsletter with a link to our latest blog post. This week’s newsletter was no different from ones we’ve sent in the past.

    This article was written with a tongue-in-cheek intro and conclusion designed to make a boring subject (using an FBA revenue calculator) into a more interesting one. Our goal for this blog post was to teach people how to calculate their FBA fees, but we also like to exercise our creativity while we’re teaching.

    Thank you for your interest in learning how to turn part-time hours into a full-time income through Amazon FBA! We will continue to work towards providing valuable content through this blog and are grateful for the supportive words for the information we provided above.

  13. I don’t know what you negative people are talking about. I have seen people doing just what they said that scary movie was talking about. In fact before my education on scanning I thought that scary movie was how it was done. Obviously so have others. Weather or not there is even a movie about it or not, it caught my attention and I for one am happy that it did. You all may be much more advanced than me, but I’m sure it did not come without a stumble here and there, I’m sure that ones who appreciate this blog and would have taken that road are happy the bloggers wrote it. If you’re so advanced then why are you on this blog for anyway? I appreciate all you do, and many others as well!

  14. Hello, and thanks for the video. Is the FBA calculator usually pretty accurate? I’m asking because I’ve discovered that quite often (not always, but most of the time), when I’ve typed in a list price that ends up putting me ‘in the red’ at the bottom, and then I add that -negative amount to my ‘list price’ in order to see what the price would be if the net profit blank comes out even (just to get an idea of what the starting point would be for me to start deciding on an actual profit-making list number), instead of coming out $0.00 (even), it shows me a profit of $8.88– which makes absolutely no sense, since that is higher than the theoretical listing price I typed in. I am inclined not to believe it. Especially since if I again change the list price to a just a penny more, the ‘net profit’ now changes to a 0.01. Huh? Yet this keeps happening on more and more items. I am obviously a new FBA seller and could use some advice! Thanks! I hope this is understandable and not too hard to follow. 🙂
