Calculate Amazon seller fees, profit margins, net revenue & ROI instantly
An Amazon FBA (Fulfillment by Amazon) calculator helps sellers estimate fees, profit margins, and net revenue before listing products. Amazon charges referral fees (typically 8–15%), FBA fulfillment fees, and monthly storage fees. This tool calculates all of them so you can make data-driven sourcing decisions.
Referral Fee: A percentage of the selling price (varies by category, typically 15%).
Fulfillment Fee: Based on product size and weight (e.g., $3.22 for small standard items).
Storage Fee: Monthly fee per cubic foot stored in Amazon warehouses.
Net Profit = Selling Price − Product Cost − Referral Fee − FBA Fee − Storage
Selling price: $25 | Product cost: $8 | Shipping: $2 | Referral fee (15%): $3.75 | FBA fee: $3.22
Net Profit = $25 − $8 − $2 − $3.75 − $3.22 = $8.03 (32% margin)
Most successful FBA sellers aim for 25–40% net profit margin after all Amazon fees. Below 15% is generally considered too risky after accounting for returns and advertising costs.
