About EcomFees

Free, independent calculators that show what you actually keep after marketplace fees.

EcomFees exists to answer one deceptively hard question every online seller has: after all the fees, what do I actually make? Marketplace fee schedules are scattered across referral percentages, fulfilment tiers, payment processing, per-order charges, regional VAT and category exceptions. It is easy to price a product, sell it, and discover the margin was thinner than you thought.

We turn those published fee schedules into simple calculators. You enter your price and costs; the tool shows the fee breakdown and your net profit and margin — before you commit to inventory.

What we cover

Today EcomFees has calculators for Amazon FBA,eBay, Etsy and Shopify, across multiple regions (US, UK and Germany), plus plain-language fee reference pages for each. We add marketplaces and countries over time.

How we research fees

Fee data is taken from each marketplace’s official pricing pages and rate cards wherever they are publicly available. Where a marketplace gates its rates or publishes them inconsistently by region, we triangulate across multiple independent sources and label our confidence. Every calculator notes when its data was last reviewed, and we always tell you to confirm against the marketplace’s official schedule and your own account, because rates change.

How we keep it free

The site is supported by advertising and may include affiliate links to seller tools in the future. This never changes the fee figures shown — those come from published rates. See our Privacy Policy andTerms & Disclaimer for details.

Independent

EcomFees is not affiliated with Amazon, eBay, Etsy, Shopify or any other marketplace. We are a small independent project built to be genuinely useful to sellers.
