FBA Fee Calculator

Understanding Amazon FBA Fees

Fulfillment by Amazon (FBA) is the most popular fulfillment method for cross-border sellers, offering access to Amazon Prime customers and simplified logistics. However, FBA fees can significantly impact your profitability if not properly understood and calculated. The three main components of FBA costs are fulfillment fees, storage fees, and referral fees.

FBA fulfillment fees are based on product size and weight, categorized into tiers ranging from Small Standard to Special Oversize. For most cross-border sellers from China, products fall into the Standard or Large Standard tiers. A small standard item weighing under 425g costs approximately $3.22 per unit to fulfill, while a large standard item between 0.91-1.36kg costs around $6.50. Understanding which tier your product falls into is essential for accurate cost forecasting.

Storage Fees and Seasonal Variations

FBA storage fees vary dramatically by season. From January through September, standard storage rates are approximately $0.87 per cubic foot per month. However, during Q4 peak season (October through December), rates nearly triple to $2.40 per cubic foot. This seasonal pricing makes inventory management crucial — overstocking during Q4 can devastate your margins, while understocking means missing the highest-demand period.

Cross-Border FBA Considerations

For Chinese sellers shipping inventory to FBA warehouses, there are additional costs to consider beyond the FBA fees themselves. These include international shipping to Amazon fulfillment centers, customs duties on inbound inventory, and the cost of compliance labeling and packaging to meet Amazon requirements. Sellers must also factor in Amazon's Long-Term Storage Fees for inventory that remains unsold for more than 365 days.

FBA Fees Across Markets

FBA fee structures differ between Amazon US, UK, Germany, and Japan. Generally, US FBA fees are the highest, while Japan tends to be the most affordable. European markets fall somewhere in between. Our calculator lets you compare fees across all four major FBA markets to help you determine where your products will be most profitable.
