Understanding Amazon FBA Fees

Amazon FBA (Fulfillment by Amazon) handles storage, packing, shipping, and customer service for your products. In exchange, Amazon charges several types of fees.

Referral Fees

The referral fee is Amazon commission on every sale. It is calculated as a percentage of the total sale price (including shipping). Rates vary by category from 8% (Consumer Electronics) to 45% (Amazon Device Accessories). Most categories charge 15%.

FBA Fulfillment Fees

Fulfillment fees cover picking, packing, shipping, and customer service. These fees depend on your product size tier (Small Standard, Large Standard, or Oversize) and weight. Small Standard items under 12 oz cost $3.22. Large Standard items start at $4.02 for items under 1 pound.

Storage Fees

Monthly inventory storage fees are charged based on the daily average volume (measured in cubic feet) that your inventory occupies in fulfillment centers. Standard-size items cost $0.87 per cubic foot from January to September and $2.40 from October to December.

Additional Fees

Other potential fees include inbound placement service fees ($0.21-$2.16 per unit), low inventory level fees, returns processing fees for certain categories, and long-term storage fees for inventory held over 365 days.

Frequently Asked Questions

How much are Amazon FBA fees?

Amazon FBA fees consist of two main components: the referral fee (8-15% of sale price depending on category) and the fulfillment fee (based on product size and weight). For a standard small item under 12 oz, the fulfillment fee is $3.22. Larger items have higher fees. Additional fees include monthly storage ($0.87/cubic foot) and inbound placement fees.

What is the Amazon referral fee?

The Amazon referral fee is a commission Amazon charges on every sale. It ranges from 8% to 45% depending on the product category. Most categories charge 15%. For example, if you sell a product for $30 in the Home & Garden category (15% referral fee), Amazon keeps $4.50 as the referral fee.

What is the minimum profit margin for Amazon FBA?

Most successful Amazon FBA sellers aim for at least a 30% profit margin after all fees and product costs. This provides enough buffer for price competition, returns, and unexpected costs. Some high-volume sellers operate on lower margins (20-25%) while niche products can sustain 40-50% margins. Use our calculator to ensure your products meet your target margin.

How do I calculate my Amazon FBA profit?

To calculate Amazon FBA profit, subtract all costs from your sale price: Net Profit = Sale Price - Product Cost - Referral Fee - FBA Fulfillment Fee - Storage Fees - Inbound Fees. For example, selling a $25 product that costs $8 to source: Referral fee (15%) = $3.75, FBA fee = $4.02, Storage = $0.15. Net profit = $25 - $8 - $3.75 - $4.02 - $0.15 = $9.08 or 36% margin.
