Amazon FBA Fees Explained: Complete 2026 Breakdown
Quick Definition
Amazon FBA fees include a referral fee (8-20% of selling price), a fulfillment fee ($3-$10+ per unit based on size/weight), and monthly storage fees ($0.87-$2.40 per cubic foot).
Referral Fee (Commission)
Amazon charges a percentage of every sale as a referral fee. The rate varies by category: most categories are 15%, Electronics and Computers are 8%, Clothing is 17%, Jewelry is 20%, and Grocery is 8%. This is the largest single fee for most sellers. There's also a minimum referral fee of $0.30 per item — relevant only for very low-priced products.
FBA Fulfillment Fee
This covers picking, packing, shipping, and customer service. It's based on the product's size tier and shipping weight. Small standard items (under 15oz, fitting in a small box) start around $3.22. Large standard items range from $3.86 to $6.44+. Oversize items jump to $9.73+. The fee increases with weight — every additional pound over 3 lbs adds roughly $0.32 for standard and $0.42 for oversize.
Monthly Storage Fees
Amazon charges for warehouse space based on cubic footage. Off-peak (January-September): $0.87 per cubic foot. Peak season (October-December): $2.40 per cubic foot — nearly 3x more. Products sitting longer than 365 days incur an aged inventory surcharge of $6.90 per cubic foot or $0.15 per unit, whichever is greater. Keep inventory lean to minimize storage costs.
Other Fees to Watch
Returns processing fee: charged for categories with free returns (Clothing, Shoes). Removal/disposal fee: $0.25-$1.00 per unit if you need to pull inventory. Labeling fee: $0.55 per unit if Amazon labels your products. Prep service fee: $1.00-$2.20 per unit for bubble wrap, poly bagging, etc. Long-term storage fee: applies monthly for inventory aged 271-365+ days.
