What Are Amazon FBA Fees?
Amazon FBA (Fulfillment by Amazon) charges sellers multiple fees for storing, picking, packing, and shipping products. Understanding these fees is essential because they can consume 30-45% of your selling price if you're not careful.
The three main fee categories are: referral fees (commission on each sale), fulfillment fees (pick, pack, and ship), and storage fees (monthly warehouse charges).
Amazon FBA Fee Breakdown
- Referral Fee: 8-15% of the selling price depending on the product category. Most categories are 15%
- FBA Fulfillment Fee: Based on product size and weight tier. Small standard items start around $3.22, large items can exceed $8-15+
- Monthly Storage Fee: $0.87 per cubic foot (Jan-Sep), $2.40 per cubic foot (Oct-Dec peak season)
- Aged Inventory Surcharge: Additional fees for inventory stored over 181 days — starts at $0.50/cubic foot and increases with age
- Inbound Shipping: Your cost to ship products to Amazon fulfillment centers
How to Maximize FBA Profitability
- Right-size packaging: Amazon charges by size tier — reducing dimensions by even 1 inch can drop you to a lower (cheaper) tier
- Avoid long-term storage: Run promotions or remove inventory before the 181-day surcharge kicks in
- Target 30%+ margins: After all Amazon fees, aim for at least 30% net margin to cover ads and business expenses
- Use FBA fee calculator: Always calculate fees BEFORE sourcing a product — many products are not profitable on Amazon
