Store-Wide Margin Calculator

This tool takes just two aggregate numbers — total revenue and total COGS — for a fast top-level margin check. Ecommerce Profit Calculator breaks costs into six categories (COGS, platform fees, ad spend, returns, overhead) for a more complete net-profit picture.

Gross margin — it only subtracts COGS, not operating expenses like ads, platform fees, or overhead. Your actual net margin will be lower than the figure shown here.

Your total cost of goods sold across all products sold in the period — not operating expenses like marketing or rent.

The tool notes >40% as a common target for a healthy ecommerce store, though this varies significantly by product category and business model.
