Understanding what you are being charged for FBA fulfilment and storage

This can be a bit tricky.  There are several methods to discover what you are being charged at a product level.

Fulfilment fees

  • FBA fee preview report.  This should in theory have the fulfilment fees your FBA inventory, but in practise quite a few items are missing.  See an annotated file here.
  • Inventory screen.  By clicking on FBA fees you can see the fulfilment fee for that market. 

Storage fees

The Monthly storage Fee report will give estimated monthly storage cost per ASIN in your inventory.  If you do not want to go this granular, simply divide the storage cost by the number of orders.
