Hi @Seller_XIUM2bnR5DMet,

Thank you for reaching out on the Seller Forums!

Please note that on August 29, 2023, the FBA Small and Light program was closed and Low-Price FBA rates were introduced. You can find more information on Low-Price FBA fees right here.

Now for Monthly inventory storage fees, I would recommend referencing the following resources:

• Monthly inventory storage fees help page
• Monthly storage fees report

For Referral Fees, please check out these pages for more information and best practices:

• Referral fees help page
• Referral Fee Preview report

Lastly, here are a few helpful tools that I would recommend checking out:

• Revenue Calculator (just confirming, is this the report you are having issues with?)
• Fee Preview report
• Manage Your Inventory – Estimated fee per unit sold

Please let me know if this helps! And of course, if you have any additional questions.

All the best,

Jameson
