Amazon FBA storage fees in 2026 remain a critical factor in seller profitability. Understanding the structure of monthly, seasonal, and long-term fees can help you optimize inventory and reduce unnecessary costs.
Project your own exposure with the free 6 month inventory storage calculator — it applies the 2026 aged-inventory tiers month by month.
Standard-size items (up to 10 lbs) are charged $0.75 per cubic foot per month. Oversize items are tiered: small oversize (10–20 lbs) costs $0.48 per cubic foot, and large oversize (over 20 lbs) costs $0.96 per cubic foot. These rates apply year-round unless overridden by seasonal adjustments.
From October through December, Amazon applies a 20% surcharge to all storage fees. This means standard items effectively cost $0.90 per cubic foot, and large oversize items cost $1.15 per cubic foot during peak season. Plan inventory levels carefully to avoid high costs during this period.
Inventory stored over 365 days is subject to long-term storage fees: $6.90 per cubic foot or $0.15 per unit, whichever is greater. This fee is assessed monthly and applies regardless of item size. Items over 181 days receive a monthly notification, but the fee only triggers after 365 days.
High inventory turnover reduces storage costs significantly. For example, a product that sells out in 60 days incurs only 2 months of storage fees, while one sitting for 12 months may incur long-term fees. Monitor your sell-through rate and adjust replenishment cycles accordingly.
