Hi @Seller_OtafmJvVqKGcj,

The Monthly Storage Fees report could be a good starting point. It shows an estimate of storage fees for each ASIN stored in Amazon’s fulfillment centers, broken down by month. You can find it under Amazon Fulfillment Reports here: https://sellercentral.amazon.co.uk/reportcentral/STORAGE_FEE_CHARGES/1

If you’re looking for more detailed or exact annual storage costs, the Payments Settlement Reports might help. These reports include all revenue and fees, including storage, but require a bit more effort. You’d need to download all settlement reports for the year, filter for storage costs, and sum them up by SKU. Tools like Excel or Google Sheets make it easier—using a pivot table can help organize and calculate the data.

I hope that helps! Michael
