What Is An Amazon FBA Calculator?
An Amazon FBA Calculator is a tool that helps Amazon sellers to calculate their profits and costs for selling on Amazon.
FBA Calculators are also a fantastic tool for market research.
When sellers would like to know how much potential profit they could make on a product that they are looking to sell in the future, these tools are a great way to get an accurate idea of their future profit margins, return on investment (ROI), and any other fees that may be included.

What is Amazon FBA?
FBA simply means – fulfillment by Amazon.
As an FBA seller, you’ll send all of your inventory to their warehouses where they will store it for you at their facilities. When you generate sales, they pick the items off the shelves, pack them up, and ship them out to your customers on your behalf.
They handle all returned items and refunds too, so you’ll never have to handle any of your orders yourself. Amazon will fulfill them for you.

How to Use Amazon FBA Calculator?
The way that FBA calculators work is quite simple.
You just need to input the product’s ASIN number, which stands for Amazon Standard Identification Number, and the tool will do all of the hard work for you.
The ASIN can be found here on any Amazon product listing:

ASIN is a unique code for each product on Amazon and it helps the calculator to match the item with any applicable fees or discounts.
With this information, the FBA Calculator will then give you an accurate estimate of your profit margins after all costs are taken into account.
If you don’t know the product’s ASIN, most of the calculator tools have a search feature where you can type in the product’s main keyword and it will come up with a list of potential matches.
What Fees Will Amazon FBA Calculators Consider?
The fees that you will be charged for leveraging the FBA service can be broken down into 4 categories, and they are:
- FBA Fees
- Fulfillment Costs
- Storage Costs
- Other Costs
FBA Fees
These are the fees that Amazon charges you for using their platform and services.
This includes things like Referral fees, which is a percentage of each sale that you make, as well as Variable Closing Fees, which are charged based on the item price or category that the product falls into.
Fulfillment Costs
Fulfillment costs refer to the money that Amazon charges you for storing and shipping your products.
This includes things like Pick & Pack Fees, which are based on the size of the product, as well as Weight Handling Fees, which are charged based on the item weight.
Storage Costs
Storage costs refer to the money that Amazon charges you for storing your products in their warehouses. This fee changes depending on the season and is usually charged once per month as a monthly storage fee.
Other Costs
These refer to any additional fees that may be applicable, such as prep services, palletizing fees, or returns processing.

It’s still not as well-known as most other FBA tools. But Zoof is going to be a big player in the FBA seller game, because of how great the entire tool is.
The Zoof FBA Calculator Tool is probably the most user-friendly and streamlined calculator available.

4 – AMZ Scout FBA Calculator

How To Know Your Shipping Fees When Using An FBA Calculator
In order to be able to calculate your potential profit margins, most Amazon FBA Calculators tools will ask for the cost of your shipping fees.
However, most Amazon sellers use FBA Calculators for product research purposes. You won’t know how much your shipping fees will be until you start asking freight companies for quotes.
Obviously we don’t want to keep requesting quotes for every single product that we research.
This will not only bombard our freight forwarders, but it will waste a huge amount of time waiting to receive quotes on shipping fees.
So how do we know what figure to put into the ‘Shipping Fees‘ tab on the FBA Calculator tool?
Calculate Shipping Fees In a Flash
The best way to know our potential shipping fees for a specific product, is to head to the Freightos website and click on their Landed Costs Calculator page.

This service will instantly provide you with an estimate of your total shipping fees. The fees are accurate enough to enter into your FBA Calculator tool to figure out your overall profit margins on a potential future product investment.
A tip when using both of these tools together –
To receive an estimate on your shipping fees, you first need to know your product’s dimensions.
But you won’t know your product’s dimensions just yet…
2 Easy Steps to Figure Out Product Dimensions
Step 1
I recommend using an FBA Calculator tool first, to find potential product ideas, and enter a ‘sensible guess’ for the shipping fees into your FBA Calculator.
Step 2
When you feel like you may have discovered a winning product idea, use the FBA Calculator tool to provide you with the product’s specific dimensions (Zoof is great for this).
Quick Way to Get Accurate ROI
Use the information you got in the previous steps. Then enter the dimensions into the Freightos Cost Calculator to get a more specific shipping fee.
The Frieghtos estimated shipping fee will inevitably be much more accurate than your own guess work.
Go back to a FBA calculator of you choice and input the estimated shipping fee you got from Freightos (or any other similar tool). This will then provide you with a much more accurate ROI and Profit margin.
Conclusion
Amazon FBA calculators are essential tools for any Amazon seller looking to accurately predict profit margins on products before making a purchase.
You can use any of the 5 Amazon FBA calculators in this post to accurately estimate profits and costs for selling products on the platform.
All of these tools are user-friendly, affordable (some free), and effective for Amazon sellers looking to maximize their profits on the platform.
If I were to choose one of these tools for myself, I would choose the Zoof Tool based on the cleanliness of the site. Zoof’s Chrome extension is the most user friendly and accurate extension out of the 3 tools that have one.
Good luck with your journey as an Amazon seller!
