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.

Example

ASIN B0096PBVZ8 has dimensions

  • Longest side: 24.8 cm
  • Median side: 19.6 cm
  • Shortest side: 5.59 cm
  • Weight: 0.12kg

It is a standard sized item which is not in the clothing category so that storage fee is 0.65/sq ft/month.  The Item volume is 0.096sq ft and so the storage charge per month will be £0.0624/item/month.

AS the shortest on this item >5cm it will be a standard parcel < 0.5kg and so the fulfilment fee is £2.90 to UK destinations.
