What fees does Amazon charge FBA sellers?

Two main fees: a referral fee (a percentage of the sale price that varies by category, typically 8–17%, minimum $0.30 for most categories) and an FBA fulfilment fee (a fixed amount based on the item's size and weight). Storage and optional ad costs are on top.

What is a good profit margin on Amazon?

Many FBA sellers target 15–30% net margin after referral and fulfilment fees, and an ROI of 50%+ on their landed cost. Thin-margin categories can still work at high volume, but leave room for ads and returns.

How Amazon FBA fees work

Amazon takes two bites out of every FBA sale. The referral fee is a percentage of the sale price and depends on the category — most sit at 15%, but electronics is often 8% and jewelry is 20%. On top of that, the FBA fulfilment fee is a flat amount per unit based on the item's size and weight, covering pick, pack and delivery. Storage fees and any advertising are extra. This calculator turns those into a single net-profit, margin and ROI figure so you can decide whether a product is worth sourcing before you commit.
