The official calculator on Amazon’s website can be a bit cumbersome to navigate, I use the SellerSonar FBA calculator in my own work, which makes the process much easier.
To calculate, you enter the ASIN or URL of your product, and it quickly pulls up all the necessary data, such as size and weight, and you can see the average selling price on the marketplace along with the estimated FBA fees and commissions. It breaks everything down clearly, so you can easily calculate your potential profit after all expenses. This tool is very handy because it saves time and gives you a more accurate picture of what you will actually receive from each sale compared to Amazon’s basic calculator.
