What is the Amazon FBA Fee Calculator?

Miscalculating Amazon FBA fees is one of the most common and costly mistakes FBA sellers make. Many sellers discover after launching that their profit margin is far thinner than expected — or that they're actually losing money on each sale — because they didn't account for all fee types. This calculator shows you the complete fee picture before you commit to a product.

Enter your selling price, product category, dimensions, weight, and cost of goods, and the calculator automatically determines your size tier, computes fulfillment fees, referral fees, and estimated storage costs, and shows you net profit per unit and monthly projection. All fee rates reflect Amazon's current US fee schedule.
