What is Amazon MCF?

Amazon Multi-Channel Fulfillment (MCF) lets sellers use FBA inventory to fulfill orders from off-Amazon channels — Shopify, WooCommerce, Walmart, TikTok Shop, eBay, and others. Amazon picks, packs, and ships from the same FBA warehouses used for Amazon.com orders, charging a separate MCF rate card. Inventory is shared; billing is not.

How MCF fees are estimated

This calculator models MCF cost as the sum of:

• Base MCF fulfillment fee by size tier and shipping speed.
• Fuel & logistics surcharge of 3.5% of the MCF fulfillment fee for US and Canada MCF (from May 2, 2026). For UK, Germany, and Japan the calculator disables the surcharge — verify marketplace-specific timing and rate in the MCF pricing page.
• Lithium battery surcharge when the order contains a lithium battery.
• Block Amazon Logistics surcharge when the seller opts out of AMZL routing.
• Remote area surcharge when the destination is non-contiguous US (Alaska, Hawaii, Puerto Rico, US territories).

All amounts are per order. Divide by units per order for per-unit fulfillment cost.

MCF vs FBA vs FBM vs 3PL

• FBA: Amazon.com fulfillment. No off-Amazon order support.
• MCF: Same FBA network, but applied to off-Amazon orders. Higher per-order cost than FBA in many cases.
• FBM: Self-fulfilled by the seller. Lowest fixed cost but you handle pick, pack, ship, and customer service.
• 3PL: Outsourced fulfillment. May be cheaper than MCF for steady volume but adds an integration and contract layer.

MCF tends to win when you need Amazon-grade delivery speed and already have FBA inventory, and you are willing to pay a premium for the convenience. MCF tends to lose when order volume is high, products are heavy, or destinations cluster in remote areas.

When MCF makes sense for Shopify or WooCommerce orders

• You already run FBA and want one inventory pool across channels.
• You sell lightweight, small-ticket items where the per-order premium is acceptable.
• Your customers expect Amazon-equivalent delivery speed (and you're willing to pay for it).
• You run a small catalog and don't want to set up a separate 3PL contract.

MCF is usually the wrong choice when order volume is high (3PL amortizes better), units are heavy (MCF heavy-tier fees are steep), or most orders ship to remote areas.

Why off-Amazon fulfillment costs can change margin

Off-Amazon orders do not see Amazon.com referral fees, but they still pay MCF fulfillment, surcharges, and any platform-side fee (Shopify Payments, Walmart Marketplace, etc.). The combined cost can easily exceed Amazon's blended fee stack for the same SKU. Always run the math on margin per order, not just MCF cost per order, before promoting MCF as the off-Amazon fulfillment path.

Limitations and assumptions

• Base MCF rates are planning-grade approximations. The live rate card varies by region, size tier, and shipping speed; verify before pricing.
• The 3.5% fuel and logistics-related surcharge is applied to US and Canada MCF orders (effective May 2, 2026). UK, Germany, and Japan surcharges are disabled in the math by default — verify marketplace-specific timing and rate in the MCF pricing page.
• Accessorial fees (lithium battery, Block Amazon Logistics, remote area) are modeled at typical values; actual amounts vary.
• No live call to Seller Central, MCF pricing API, or any third-party source.
• All math runs in your browser. No data leaves your device.
