Understanding Amazon FBA fees in 2026
Amazon FBA fees determine how much of your selling price you actually keep. Every FBA seller pays a combination of referral fees, fulfillment fees, and storage fees on each unit sold. Getting these numbers wrong by even a few percent can turn a profitable product into a money loser, especially for lower-priced items where margins are thin.
What fees does Amazon charge FBA sellers?
Amazon charges three core fees on every FBA order. The referral fee is a percentage of the selling price, typically 8% to 17% depending on the product category. The FBA fulfillment fee covers picking, packing, and shipping your product to the customer, and varies by size tier and weight. Monthly storage fees are charged per cubic foot of space your inventory occupies in Amazon's warehouses, with rates jumping significantly during the Q4 peak season (October through January). Additional fees may apply for aged inventory, returns processing, and low inventory levels. Use this FBA calculator to estimate all three core fees and see your net profit per unit before committing to a product or price point.
