How FBA profit is calculated
Net profit per unit is the selling price minus landed product cost (FOB + freight + duty), the referral fee, fulfillment, monthly storage, advertising at your ACoS, and the expected loss from returns. The calculator applies the greater of unit weight and dimensional weight to fulfillment, which is why a light but bulky item can cost more to ship than its scale weight suggests.
Method & data sources
Fees are modeled from Amazon's published US, Germany and Japan fee schedules and TikTok Shop's published rates. Figures on this page are as of 2026-10-02. Fee schedules change; re-run the calculator with your own inputs and treat the results as estimates, not quotes.
