Amazon FBA profit depends on several layers: referral fees, fulfillment fees, storage, inbound shipping, product cost, refunds, advertising, and category-specific rules. This calculator uses editable assumptions so you can model a product before ordering inventory or changing price. The default referral percentage is a common starting point, but Amazon referral fees vary by category and may include minimum referral fees.
For serious product decisions, compare this estimate with Seller Central, the FBA revenue calculator, and the current Amazon fee schedule. Use a conservative advertising allowance when evaluating competitive categories.
