About EcomCalc

EcomCalc is a free calculator hub for ecommerce operators who need fast estimates for pricing, platform fees, payment fees, margin, and advertising efficiency.

The tools are designed for Shopify, marketplace, and paid media workflows. Every result is an estimate, and every important fee input can be changed because platform rates vary by region, plan, card type, category, and seller account.

Calculator inputs are processed in your browser and are not uploaded to a server in the current version.
