About Ecom Profit Calculator

Ecom Profit Calculator is a free collection of ecommerce calculators for sellers, operators, and marketers who need practical product-level profit checks.

The site focuses on net profit, break-even ROAS, platform fees, shipping, payment processing, returns, and advertising cost. The goal is to help sellers understand whether a product can make money after realistic costs, not just before-fee gross margin.

Who this site is for

• Shopify profit calculator users and direct-to-consumer store owners.
• TikTok Shop profit calculator users, Etsy sellers, Amazon FBA profit calculator users, and marketplace sellers.
• Paid ads operators checking campaign economics.
• Dropshipping sellers comparing offers and landing costs.

How to use the calculators

Start with the calculator closest to your selling channel: the Shopify profit calculator, TikTok Shop profit calculator, Amazon FBA profit calculator, or break-even ROAS calculator. Update the default assumptions with your actual costs, then compare net profit, break-even ROAS, and maximum ad spend before making product or campaign decisions.
