Amazon storage fees can significantly impact your profitability, especially if you're not managing inventory levels properly. Understanding and calculating storage fees is crucial for FBA sellers.

How Amazon Storage Fees Work

Amazon charges storage fees based on:

• Cubic feet: Volume of inventory stored
• Size type: Standard vs oversize
• Season: Peak (Oct-Dec) vs non-peak
• Duration: Monthly vs long-term (365+ days)

Monthly Storage Fees

Charged monthly for all inventory, regardless of how long it's been stored:

• Standard Size (Non-Peak): ~$0.75 per cubic foot/month
• Standard Size (Peak): ~$2.40 per cubic foot/month
• Oversize (Non-Peak): ~$0.48 per cubic foot/month
• Oversize (Peak): ~$1.20 per cubic foot/month

Peak season (October-December) has 2-3x higher rates due to increased demand.

Long-Term Storage Fees

Additional fees for inventory stored 365+ days:

• Charged monthly on top of regular storage fees
• Higher rates to encourage inventory turnover
• Can significantly increase costs for slow-moving products

Real-World Example

Let's say you have 500 units of a standard-size product:

• Dimensions: 10" × 8" × 6" = 480 cubic inches = 0.28 cubic feet per unit
• Total volume: 500 × 0.28 = 140 cubic feet
• Non-peak rate: $0.75 per cubic foot

Monthly storage fee: 140 × $0.75 = $105/month

Annual storage cost: $105 × 12 = $1,260/year

If stored for 365+ days, you'd also pay long-term storage fees on top of this!

How to Reduce Storage Fees

• Manage inventory levels: Don't overstock slow-moving items
• Use removal orders: Remove slow-moving inventory before 365 days
• Optimize dimensions: Smaller packaging = lower cubic feet
• Plan for peak season: Account for higher rates Oct-Dec
• Monitor inventory age: Track how long items have been stored
