How to Use This Profit Margin Calculator

Enter your total revenue — the gross income your ecommerce business earned over a given period. This is the top line before any costs are subtracted. Use monthly figures for the most actionable insights, or annual figures for a big-picture view.

Enter your cost of goods sold (COGS) — the direct costs tied to delivering your product or service. For ecommerce businesses, this typically includes Cost of goods sold (inventory) and Shipping and fulfillment. The calculator subtracts this from revenue to show your gross profit and gross margin.
