Running an Amazon FBA (Fulfillment by Amazon) business is exciting, but it also comes with several costs you need to manage. One of the most significant yet often overlooked expenses is Amazon storage fees. Whether you’re storing small items or large products in Amazon’s fulfillment centers, knowing the storage cost in advance helps you plan better, optimize inventory, and maximize profits.
Amazon Storage Fee Calculator
What Are Amazon Storage Fees?
When you store products in Amazon’s fulfillment centers, Amazon charges you a fee based on the space your items occupy (volume in cubic feet) and the duration they remain in storage.
Amazon has two main types of storage fees:
- Monthly Storage Fees – Charged per cubic foot of storage space. Rates vary depending on the time of year (higher during October–December due to holiday demand).
- Long-Term Storage Fees – Applied to inventory stored for more than 181 days or 365 days, depending on the product type.
If you’re serious about keeping your FBA business profitable, calculating these fees before sending inventory to Amazon is crucial. That’s where our tool comes in.

Example Storage Fee Calculations
Here are some real-world examples to help you understand how the calculator works:
Example 1 – Small Item
- Item volume: 0.5 cubic feet
- Storage duration: 6 months
- Amazon storage rate: $0.75 per cubic foot per month
Monthly fee = 0.5 × $0.75 = $0.38
Total fee = $0.38 × 6 = $2.28
👉 Storing this small product for half a year only costs $2.28.
Example 2 – Medium Item
- Item volume: 2 cubic feet
- Storage duration: 3 months
Monthly fee = 2 × $0.75 = $1.50
Total fee = $1.50 × 3 = $4.50
👉 Storing a medium item for 3 months will cost $4.50.
Example 3 – Bulk Inventory
- Item volume: 10 cubic feet
- Storage duration: 12 months
Monthly fee = 10 × $0.75 = $7.50
Total fee = $7.50 × 12 = $90.00
👉 A bulkier product stored for one year will cost $90 in storage fees.
