Understanding Amazon FBA Fees

Amazon FBA (Fulfillment by Amazon) handles storage, packing, and shipping for your products, but the fees can eat into your margins if you are not careful. This calculator gives you a clear breakdown of all costs so you can price products profitably.

FBA Fee Components

Referral Fee: A percentage of the selling price that Amazon charges for every sale. Rates vary by category, typically 8% for electronics and up to 17% for clothing and accessories.
Fulfillment Fee: A flat fee per unit based on the size tier and weight of your product. Small, lightweight items cost as little as $3.22 to fulfill, while oversized items can cost significantly more.
Monthly Storage Fee: Charged per cubic foot of space your inventory occupies in Amazon's warehouses. Rates jump significantly during Q4 (October through December) to $2.40/cu ft compared to $0.87/cu ft the rest of the year.

Tips to Maximize Your FBA Margins

Optimize product size: Even a small reduction in packaging dimensions can drop you into a lower size tier, saving $1–$3 per unit.
Manage inventory levels: Avoid long-term storage fees by keeping 2–3 months of inventory at Amazon at any given time.
Source at lower costs: Negotiate with suppliers or consider alternative sourcing to improve your COGS and boost per-unit profit.
Price strategically: Aim for a minimum 30% profit margin after all fees. Products priced between $15 and $50 tend to have the best balance of volume and margin.
