What is an Amazon FBA Calculator?

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.

How Amazon FBA Fees Work

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

Example Calculation

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)
