Frequently Asked Questions
How do I calculate my e-commerce profit margin?
Profit Margin = ((Selling Price − Cost) ÷ Selling Price) × 100. For accurate results, include ALL costs: product cost, shipping, packaging, platform fees, and marketing spend. Use our free Profit Margin Calculator for instant results.
What is unit economics and why does it matter?
Unit economics measures the profitability of a single product sold after ALL costs — COGS, taxes, packaging, shipping, advertising, cancellations, and returns. It tells you whether each sale actually makes money or loses money.
