Overview

The FBA fulfillment fee — formerly known as the "pick and pack" fee — is a per-unit charge that Amazon assesses every time it fulfills an order on a seller's behalf through Fulfillment by Amazon. This fee covers the cost of picking, packing, shipping, and handling customer service for each unit sold. Understanding how this fee is calculated is essential for every FBA seller, as it directly impacts per-unit profitability and pricing strategy.

Key Points / What Sellers Need to Know

• Per-unit charge — The FBA fulfillment fee is applied to every individual unit that Amazon ships to a customer, making it one of the most significant recurring costs for FBA sellers.
• Based on size, weight, and category — The fee amount varies depending on the product's size tier (small standard, large standard, small oversize, large oversize, etc.), its shipping weight, and in some cases its product category.
• Updated annually — Amazon typically publishes updated rate cards each year, and sellers should review the 2026 fee schedule to ensure their pricing models remain accurate.
• Special program rates may apply — Products enrolled in programs such as Low-Price FBA, the FBA New Selection program, or Multi-Channel Fulfillment may have different fee structures or receive temporary discounts.
• Separate from other FBA fees — The fulfillment fee is distinct from storage fees, removal fees, and other charges. It specifically covers the logistics of getting a product from Amazon's warehouse to the customer's door.

How the Fee Is Calculated

Amazon determines the FBA fulfillment fee by first classifying each product into a size tier based on its dimensions and weight. Standard-size items — those that fall within Amazon's defined limits for length, width, height, and weight — generally carry lower fulfillment fees than oversize items. Within each size tier, the fee increases incrementally with shipping weight. Amazon uses "dimensional weight" or actual weight, whichever is greater, to calculate the shipping weight for fee purposes. Sellers can use the FBA Revenue Calculator in Seller Central to estimate fulfillment fees for specific ASINs before committing inventory to FBA.
