Understanding Amazon FBA Storage Fees

Amazon FBA storage fees are charges for storing your inventory in Amazon's fulfillment centers. These fees are based on the volume of space your products occupy and the time they remain in storage.

1. Monthly Storage Fees

Monthly storage fees are charged based on the cubic feet your inventory occupies in Amazon's warehouses. The rates vary by month (higher during Q4 holiday season) and by storage type (standard vs. oversized).

2. Long-Term Storage Fees

Long-term storage fees apply to items that have been in storage for more than 365 days. These fees are charged quarterly (on the 15th of February, May, August, and November) and are calculated based on the volume of long-term inventory.
