Overview

Amazon's Multi-Channel Fulfillment (MCF) program allows sellers to use their existing FBA inventory to fulfill orders from sales channels outside of Amazon, including Shopify stores, eBay listings, and custom websites. Understanding MCF's fee structure is essential for sellers who want to leverage Amazon's logistics network for their entire ecommerce operation. With updated fees taking effect on January 15, 2026, sellers should review the latest rate tables to accurately forecast their fulfillment costs.

Key Points / What Sellers Need to Know

• 2026 Fee Update — Amazon has announced updated MCF fees effective January 15, 2026. Sellers should review the new rate schedules on Seller Central to understand how their costs may change and plan inventory strategies accordingly.
• Peak Period Surcharges Apply — A peak fulfillment fee applies to all MCF orders in the US from October 15, 2025, through January 14, 2026. This surcharge reflects the increased operational costs during the holiday season and impacts every MCF shipment during that window.
• Size Tier Determines Your Rate — MCF fees are calculated based on your product's size tier classification and shipping weight. Products are categorized into small standard, large standard, small oversize, medium oversize, large oversize, and special oversize tiers, each with different fee schedules.
• Multiple Shipping Speeds Available — MCF offers several click-to-delivery speed options, including Standard (3-5 business days), Expedited (2 business days), and Priority (next business day). Faster delivery speeds come with higher per-unit fulfillment fees.
• Fee Preview Tools Exist — Sellers can preview their MCF fees before committing by integrating with Amazon's fee preview API. This helps sellers price their products correctly across all channels.

How MCF Fees Are Calculated

MCF fulfillment fees are determined by three primary factors: the product's size tier, its shipping weight, and the selected delivery speed. To calculate your fee, you first need to determine your product's size tier by measuring its dimensions and weight. Amazon classifies products into tiers ranging from small standard-size items to special oversize, with each tier carrying progressively higher fees. The shipping weight used for fee calculation is the greater of the actual unit weight or the dimensional weight, with dimensional weight calculated by dividing the product's volume (length x width x height) by a standard divisor. Once you know your size tier and shipping weight, you can reference the appropriate rate table for your chosen delivery speed to find your per-unit fulfillment fee.
