About Amazon FBA Calculator

Model an FBA sale with the two fees that dominate it: the category referral fee (15% for most categories) and the per-unit FBA fulfillment fee, which depends on your product's size tier. Both are editable, plus a slot for averaged storage and other fees. Add your product cost to see profit and margin per unit.

Common uses

Limitations

  • Rates are editable defaults based on publicly listed standard fees — always confirm current fees with the platform
  • Referral and fulfillment fees vary widely by category and size tier — look up your exact product's fees in Seller Central.
