Ecommerce Profit Calculator

This tool breaks costs into six categories (COGS, platform fees, ad spend, returns, overhead) for a detailed net-profit view. Store-Wide Margin Calculator only takes total revenue and total COGS as one lump figure — faster to fill in, but no cost breakdown.

Enter 0 for any category you don't track separately, or fold it into 'Overhead' — the calculation still works, you'll just lose the per-category breakdown that makes this tool useful.

No — this is a pre-tax operating profit figure based on the six cost inputs you provide.

It varies widely by category (fashion/beauty often 10-20%+, low-ticket dropshipping can be under 10%) — there's no single benchmark, compare against your own history and close competitors.
