eBay Profit Margin Calculator
Estimate your eBay profit, profit margin, and return on cost after item costs, shipping, fees, and ad spend.
Overview
Use this eBay Profit Margin Calculator to estimate how much profit you keep from a sale after item cost, shipping, eBay fees, fixed transaction fees, ad spend, and any extra selling costs. It is useful for checking pricing before you list or reviewing how profitable a sold item really was.
How it works
The calculator starts with your sale price and subtracts all entered costs, including the item cost, shipping cost, percentage-based eBay fees, any fixed fee, advertising cost, and other expenses. Profit margin is then calculated as net profit divided by sale price, while return on cost compares profit to your total cost base. This gives a simple view of whether the sale leaves enough room for profit.
