The FBA Inventory Age (sign-in required) gives you information about the age of your Fulfilment 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 fulfilment centre. FBA accounts for inventory on a first-in-first-out basis across our entire fulfilment network. This means that each sale or removal will be applied to the inventory that has been in our fulfilment network the longest, regardless of which physical unit was actually shipped or removed.
The inventory age buckets include all inventory in our fulfilment centres except pending removals and liquidations: Total stored inventory units = Available units + Unfulfillable units + Researching units. 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 unfulfillable units or units in researching status, it will not appear.
For information about current FBA long-term storage fees and policy, see our FBA Long-Term Storage help page. The Inventory age view shows your LTSF-eligible units and the estimated LTSF amount as of the next charge date, assuming no further sales. You can click on the estimated LTSF to see a breakdown of the unit counts and LTSF amount for the next assessment date.
Our goal is to help you easily identify aged inventory that may incur Long-Term Storage Fees and provide recommended actions aimed at helping you manage the investment return on your inventory more effectively. In some cases, the recommendation may be to remove units from your inventory but, 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 the Units sold column. The Sell-through column allows you to see your sales divided by the average number of units available at fulfilment centres 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:

An alert that indicates that fewer customers are buying the product after looking at the listing, relative to other listings in the same category.
An alert that indicates that the ASIN listing has a low number of viewers compared with other ASINs in the same category.
The rate at which your units sold and shipped over the past 90 days, divided by the average inventory available at fulfilment centres during that time period. Tracking your sell-through rate can help you determine whether you need to take action to improve traffic or conversion for your products.
See the IPI FAQ to learn how to calculate your sell-through.
The sales price recommended to help you sell through your inventory based on your current inventory settings. This value may be different from the lowest price or Buy Box price. We recommend that you keep your product at this price until you have sold through your excess inventory.
If a sale is recommended, this is the estimated number of days for the sale that would likely help you sell through your excess inventory.
Estimated quantity of inventory that would likely benefit from removal instead of incurring storage fees.
