How the Amazon FBA Calculator works
These calculators use the standard, published fee structures of the major marketplaces and platforms — Shopify, Amazon FBA, Etsy and eBay — including referral, transaction, payment-processing and fulfilment fees. By combining those with your product cost and price, they show your real profit and margin per sale rather than just revenue.
All calculations run privately in your browser.
Tips & best practices
- Favour small, light products to keep the size-based fulfilment fee low.
- Leave room in your margin for advertising and returns, which the headline fees do not include.
- Recalculate whenever Amazon changes its fees, which happens regularly.
