Amazon has dropped the details for the 2026 FBA fee structure, and the message to sellers is unambiguous: Move it or lose it. While referral fees often grab the headlines, the expansion of the Aged Inventory Surcharge is the silent killer that will erode margins for unprepared sellers.

What is Changing?

Amazon is introducing stricter penalties for inventory that sits in their fulfillment centers.

• The 12-15 Month Hike: Previously ~$0.15/unit, this fee is doubling to $0.30/unit for Amazon USA.
• The New >15 Month Tier: A dedicated tier for older stock charging $0.35/unit or $7.90/cubic foot.

The "Inventory Health" Reality Check

In the past, you might have ignored a few boxes of slow-selling units in the corner of the FBA warehouse. Under the new rules, those boxes are actively draining your account balance.

1. The "Sunk Cost" Fallacy

Many sellers hold onto stock thinking, "I'll sell it eventually and make my money back." With a $0.35/unit monthly recurring fee, "eventually" is too expensive. You must shift your mindset from "Profit Preservation" to "Capital Recovery." It is better to get cash back now at a lower margin than to bleed fees for another 6 months.

2. The Inbound Logistics Shift

This fee change forces a change in how you ship.

• Old Way: Send 5,000 units to cover 6 months of sales to save on shipping.
• New Way: Send 1,000 units every month. Yes, your shipping work increases, and your per-unit freight might tick up slightly. But you completely eliminate the risk of getting hit with massive storage surcharges if demand drops.

3. Data-Driven Decisions

You cannot manage this by "feel." You need to know your exact sell-through rate per SKU. If a SKU sells 0.5 units a day, and you have 500 units in stock, you are in the danger zone.
