How We Calculate FBA Estimated Storage Fees

We pull the Inventory Report from Amazon. This report includes a field called Estimated Storage Fees, which Amazon defines as:
"Estimated storage fees (monthly storage + storage utilization surcharge + aged inventory surcharge) that you would incur 30 days from today, based on your current sales rate."

How We Use This Data

To make the estimated fees useful for your daily P&L reports, we follow this straightforward process:

  1. Daily Retrieval:
    Each day, we fetch the latest Estimated Storage Fee value from Amazon for each of your inventory items.

  2. Daily Allocation:
    Since Amazon’s estimate covers 30 days, we divide the total Estimated Storage Fee by 30. This gives us the estimated daily storage fee for each item.

  3. Adding to P&L Reports:

    • For any day in your P&L report that doesn’t yet have an actual storage fee (because Amazon hasn’t charged it yet), we include the calculated estimated daily storage fee.

    • Once Amazon charges the actual storage fee, the estimate is replaced with the real value.
