How Much Does Amazon FBA Cost Per Item? A Complete Breakdown

Before you send inventory to Amazon warehouses, you need a clear per-unit cost model. “How much does Amazon FBA cost per item?” is the wrong question if you are only thinking about fulfillment. The real cost includes referral fees, inbound shipping, storage, and returns.

Per-Item Cost Components

1. Product cost - What you paid the manufacturer or supplier.
2. Inbound shipping - Freight to Amazon fulfillment centers, usually $0.50 to $2.00 per unit depending on volume and origin.
3. Referral fee - 8% to 45% of selling price by category. Most items pay 15%.
4. Fulfillment fee - Based on dimensions and weight. Small standard items start at $3.22.
5. Storage fee - Averages $0.87/cu ft in off-peak months. For a single unit, this is pennies per month unless it sits for a year.
