The eBay Fee Calculator app is a Chrome extension that calculates selling fees, profit, and correct sale price. It is a useful tool for eBay sellers, retailers, and small business owners who need to know their eBay profit, as well as what it would take to sell the same product for the same price as their competitors. The eBay Fee Calculator gives sellers the ability to instantly calculate their profit on any item, and also shows them how much profit they would need to break even.

It is an eBay user-friendly tool that is easy to use, and it also has an integrated option that can be used to search for competitors and see their prices. The seller can get an estimate on what it would take to break even with each competitor, and they can use the results to decide if they can price their items at a profit or if they should price them less.
