Frequently asked questions

How much does Amazon take from sellers?

Amazon takes a referral fee of 8–20% depending on category (15% for most), plus an FBA fulfilment fee of roughly $3.22–$9.73 per unit for standard sizes, plus monthly storage. In practice most FBA sellers lose 30–40% of the selling price to Amazon.

How do I calculate Amazon FBA profit?

Profit = selling price − referral fee − FBA fulfilment fee − storage − product cost − inbound shipping. This calculator applies all of them and also shows margin, ROI and break-even price.

What is a good ROI for Amazon FBA?

Most experienced sellers target at least 100% ROI (a 2× return on landed cost) and a 25–35% net margin. Below 50% ROI a single price war, return spike or fee change can wipe out the profit.

What is the Amazon referral fee in 2026?

15% for most categories, 8% for electronics, computers and grocery, 17% for clothing and up to 20% for jewellery, with a $0.30 minimum per item.

Does this Amazon FBA calculator work for the UK?

Yes — switch the marketplace to Amazon.co.uk, Amazon.de or Amazon.ca and enter local prices. Referral percentages are broadly the same; fulfilment fees vary slightly by marketplace.

What is my Amazon break-even price?

It is the price where profit is exactly zero after referral fees, FBA fees and your landed cost. Never accept a coupon, deal or PPC bid that pushes your net price below it.
