Overview

Amazon's Fulfillment by Amazon (FBA) program allows sellers to store inventory in Amazon's fulfillment centers, where Amazon handles picking, packing, shipping, returns, and customer service on the seller's behalf. Understanding the full range of FBA fees and optional services is essential for any seller looking to maintain healthy profit margins while leveraging Amazon's logistics infrastructure.

This reference page serves as the central hub for all FBA-related costs and services, making it a must-bookmark resource for both new and experienced sellers.

Key Points / What Sellers Need to Know

• FBA fees are multi-layered — Sellers pay fulfillment fees per unit shipped, monthly storage fees for inventory held in warehouses, and may incur additional charges for optional services or policy violations.
• Fulfillment fees are size and weight-based — Amazon categorizes products into size tiers (standard-size, oversize, etc.) and charges accordingly, so accurate product dimensions are critical.
• Storage fees vary by season — Monthly inventory storage fees increase significantly during the Q4 peak season (October through December), making inventory planning essential.
• Optional services carry additional costs — Features like FBA Label Service, FBA Prep Service, Multi-Channel Fulfillment, and removal/disposal orders each have their own fee structures.
• Fee changes occur regularly — Amazon typically announces annual fee updates that take effect in January or February, with additional adjustments possible throughout the year.
• Aged inventory surcharges apply — Inventory that sits in fulfillment centers for extended periods is subject to aged inventory surcharges, incentivizing sellers to maintain efficient stock turnover.

How FBA Fees Work

FBA fees are designed to cover the end-to-end cost of Amazon handling your logistics. The two primary fee categories are fulfillment fees and inventory storage fees. Fulfillment fees are charged per unit and cover the cost of picking your product from the shelf, packing it into a shipping box, delivering it to the customer, and processing any returns. These fees are determined by the product's size tier and shipping weight, which Amazon calculates based on the item's dimensions and actual weight. Sellers should ensure their product listings have accurate weight and dimension data, as discrepancies can lead to higher-than-expected fees or the need to file a cubiscan dispute.
