Amazon FBA Storage Fees Explained - Complete Guide 2025

Understanding Amazon FBA storage fees is crucial for managing inventory costs. These fees can significantly impact your profitability, especially during peak season when rates triple. This comprehensive guide explains everything you need to know about FBA storage fees.

What Are FBA Storage Fees?

Amazon FBA storage fees are monthly charges based on the volume (cubic feet) your inventory occupies in Amazon's fulfillment centers. These fees cover the cost of storing your products in Amazon's warehouses.

Key Points:

  • Charged monthly on the 7th-15th of each month
  • Based on average daily volume stored
  • Different rates for standard vs oversize items
  • Rates triple during peak season (October-December)

2025 Storage Fee Rates

PeriodStandard SizeOversize
January - September$0.75 per cubic foot$0.48 per cubic foot
October - December$2.40 per cubic foot$1.20 per cubic foot

⚠️ Peak Season Warning:

Storage fees increase by 3x during October-December. A product that costs $0.75/cu ft to store in September costs $2.40/cu ft in October. Plan your inventory accordingly!

How Storage Fees Are Calculated

Formula

Storage Fee = Cubic Feet × Rate × Months

Based on average daily volume stored during the month

Example Calculation

Product dimensions: 12" × 10" × 8"

Step 1: Calculate cubic feet(12 × 10 × 8) ÷ 1,728 = 0.56 cu ft
Step 2: Monthly storage (standard season)0.56 × $0.75 = $0.42/month
Step 3: Peak season (Oct-Dec)0.56 × $2.40 = $1.34/month
For 100 units stored 3 months (including 1 peak month):$126 + $134 = $260

Long-Term Storage Fees

What They Are:

Additional fees for inventory stored in Amazon fulfillment centers for more than 365 days.

Fee Structure:

  • $6.90 per cubic foot OR
  • $0.15 per unit
  • Whichever is greater

Assessment Date: 15th of each month

Example

100 units stored for 400 days, each taking 0.1 cubic feet:

  • Total cubic feet: 100 × 0.1 = 10 cu ft
  • Fee option 1: 10 × $6.90 = $69
  • Fee option 2: 100 × $0.15 = $15
  • Long-term storage fee: $69 (whichever is greater)

Tip: Monitor inventory age and remove items before 365 days to avoid these fees.

Strategies to Minimize Storage Fees

1. Optimize Inventory Levels

Keep 30-60 days of inventory instead of 90+ days. Use sales velocity data to forecast accurately.

2. Plan for Peak Season

Reduce inventory before October to minimize Q4 storage costs. Increase inventory in January when rates drop.

3. Monitor Inventory Performance Index (IPI)

Maintain IPI above 400 to avoid storage limits. Amazon restricts storage for sellers with low IPI scores.

4. Remove Slow-Moving Inventory

Create removal orders for products that haven't sold in 90+ days to avoid long-term storage fees.

5. Optimize Product Dimensions

Smaller products take less space, reducing storage fees. Optimize packaging to minimize cubic feet.

6. Use Inventory Forecasting

Use tools to predict sales and order the right amount of inventory to avoid overstocking.

Storage Fees by Marketplace

Storage fees vary by marketplace. Here's a comparison:

MarketplaceStandard (Jan-Sep)Standard (Oct-Dec)
USA$0.75/cu ft$2.40/cu ft
UK£0.60/cu ft£2.00/cu ft
CanadaC$1.00/cu ftC$3.20/cu ft
Germany€0.65/cu ft€2.10/cu ft

Common Storage Fee Mistakes

  • Overstocking before Q4: Many sellers stock up for holiday season but forget about 3x storage fees
  • Ignoring slow-moving inventory: Products that don't sell accumulate storage fees and eventually long-term storage fees
  • Not monitoring IPI: Low IPI scores can result in storage restrictions
  • Forgetting about long-term storage: Items stored 365+ days incur significant additional fees
  • Not calculating total storage costs: Storage fees can add up quickly, especially during peak season
