What is AMZ Seller’s Calculator?

AMZ seller’s calculator designed specifically for Amazon sellers. It enables live monitoring of the market situation and helps with its correct assessment.

Using this extension, sellers can automatically calculate a large number of variables that must be taken into account when selling their products. For example, the information received regarding other sellers’ pricing allows you to set your own prices optimally, leading to maximized profit. And accumulated over time data on changes in the product characteristics allows you to make the most accurate predictions for the future.

AMZ Seller’s Calculator allows you to:

  • Calculate profit for the chosen time frame taking estimated expenses into account.
  • Calculate the number of products that will be sold per unit of time, based on that product’s Best Sellers Rank in its category.
  • Calculate Amazon seller fees.
  • Display only information relevant to the seller in a convenient measurement system.
  • View search results summarized in a table, create lists of the products you want and export those lists as .cvs files.
