Amazon FBA Fee Formula
Frequently Asked Questions
Amazon charges a referral fee on every item sold — typically 8–15% of the selling price depending on category. This fee is Amazon's commission for providing the marketplace and customer base.
The FBA fulfillment fee covers picking, packing, and shipping your product to the customer. Fees range from $3.22 for small standard items to $89.98+ for large oversize products. There are also storage fees charged monthly.
FBA is typically worth it for fast-selling, lightweight, small-to-medium products priced $15–$50+. FBA gives you Prime badge, handles customer service and returns, and improves buy box eligibility. Thin-margin or large/heavy products may be better suited for FBM (Fulfilled by Merchant).
Beyond referral and FBA fees, sellers pay monthly storage fees ($0.78–$2.40/cubic foot), long-term storage fees for slow-moving inventory, and optional advertising (PPC) costs. Professional seller accounts cost $39.99/month.
