FBA Inventory Age gives you information about the age of your Fulfillment by Amazon (FBA) inventory. The page shows you the number of units in each age group, the number of units that would be subject to the long-term storage fee on the next charge date, and the estimated long-term storage fee amount for those units, assuming no further sales. It also shows your recent sales performance for each SKU and identifies opportunities for you to increase traffic or sales conversion to help sell through your aged inventory.
You can filter your inventory by age range to see which of your products have one or more units in the age ranges you select, and then get details about the number of units in those ranges. Filtering by age range can give you a clearer look at which of your products have aged inventory so you can take steps to improve sell-through and reduce your costs by avoiding long-term storage fees.
For example, if you want to know which of your products has inventory aged 331-365 days, you would do the following:
After you have selected your age range, you can sort your products in ascending or descending order using the down arrow next to the Inventory Age column header.
Inventory age is based on the number of days a unit is in a fulfillment center. FBA accounts for inventory on a first-in-first-out basis across our entire fulfillment network. This means that each sale or removal will be applied to the inventory that has been in our fulfillment network the longest, regardless of which physical unit was actually shipped or removed.
The inventory age buckets include all inventory in our fulfillment centers except pending removals and liquidations: Total stored inventory units = Available units + Unfulfillable units + Researching. Units in researching status are not subject to long-term storage fees.
FBA Inventory Age shows any product that has at least one unit available for sale. If your product has only unfillable units or units in researching status, it will not appear.
Inventory that has been in a fulfillment center for 365 days or more is subject to a long-term storage fee of $6.90 per cubic foot or a per-unit minimum charge $0.15, whichever is greater. The fee is assessed on the 15th of each month. FBA Inventory Age shows your units that would be subject to the long-term storage fee and the estimated fee amount as of the next charge date, assuming no further sales. For more information, visit FBA long-term storage fees.
Our goal is to help you identify aged inventory that may incur long-term storage fees and provide recommended actions for better managing the investment return on your inventory. In some cases, the recommendation may be to remove units from your inventory. In other instances, we may not recommend any action if your inventory levels are not in excess. Select Improve recommendation in the drop-down menu to ensure we have accurate information for these SKUs. Several factors influence our recommendations:
Demand and sell-through
In addition to the alerts, you can also see how many units of a product have been sold over the past 7, 30, 60, and 90 days by hovering over a product’s Units sold column. The Sell-through column allows you to see your sales divided by the average number of units available at fulfillment centers during the past 90 days. If you have items you want to remove from your inventory, click Create removal order from the action menu.
In your inventory settings, you can enter details about your inventory cost structure to help us to make better recommendations. These settings include:
