How we calculate FBA estimated storage fees

We pull the inventory aging report from Amazon. This report includes a field called Estimated Storage Cost Next Month, 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 estimate useful in your daily P&L reports, we do this:

  • Daily retrieval: Each day, we get the latest Estimated Storage Cost Next Month value from Amazon for each of your inventory items.

  • Daily allocation: Amazon's estimate covers 30 days, so we divide it by 30. Estimated storage fee ÷ 30 = daily estimate for each item.

  • Adding to P&L reports: For any day in your P&L report that doesn't have an actual storage fee yet (because Amazon hasn't charged it), we include the daily estimate. Once Amazon charges the actual storage fee, the estimate is replaced with the real amount.

Frequently asked questions

Why do I see a storage fee before Amazon charged me?

It's an estimate. ConnectBooks adds it for days that don't have an actual storage fee yet, and replaces it with the real fee once Amazon charges it.

How do I hide estimated storage fees in 1 report only?

Open the P&L report, click Customize and uncheck Include Estimated Storage.
