What is Amazon FBA Storage Fee?
Amazon FBA (Fulfillment by Amazon) storage fee is the cost Amazon charges for storing your inventory in their fulfillment centers. These fees are calculated based on the cubic footage your products occupy and vary by season, product size tier, and how long items have been stored. For 2026, Amazon charges $0.78 per cubic foot per month during standard season (January–September) and $2.40 per cubic foot per month during peak season (October–December).

- 365+ days: Additional $15.60 per cubic foot
How to Calculate FBA Storage Fees
Follow these steps to estimate your monthly FBA storage costs:
- Calculate product volume: (Length × Width × Height) ÷ 1,728 = cubic feet per unit
- Multiply by units in stock to get total cubic footage
- Apply the storage rate for your size tier and season
- Add long-term surcharge if items are stored 180+ days
FBA Storage Fee Formulas
Volume per Unit (cu ft) = (Length × Width × Height) ÷ 1,728
Monthly Storage Fee = Total Volume × Rate per Cubic Foot
Period Fee = Monthly Fee × (Days ÷ 30)
Long-Term Surcharge = Total Volume × Surcharge Rate (if days > 180)
Real-World Example
Example: You have 500 units in stock, each measuring 10" × 8" × 2" and weighing 12 oz (standard size), stored for 90 days during January:
Volume per unit: (10 × 8 × 2) ÷ 1,728 = 160 ÷ 1,728 = 0.0926 cu ft
Total volume: 0.0926 × 500 = 46.30 cu ft
Monthly storage fee: 46.30 × $0.78 = $36.11
Period fee (90 days): $36.11 × 3 = $108.33
No long-term surcharge (under 180 days)
How to Reduce FBA Storage Fees
- Monitor inventory age: Remove items before 180 days to avoid long-term surcharges
- Optimize packaging: Reduce dimensional weight to lower cubic footage
- Avoid peak season bloat: Stock only what you need Oct–Dec to minimize peak fees
- Use FBA Mulberry: Leverage Amazon's康熙 removal tools to clear slow stock
- Consider FBM: For slow-moving items, fulfilling orders yourself may be cheaper
