Inventory Management
Sell-Through Rate
The number of units sold and shipped over the past 90 days divided by the average number of units in FBA inventory during that period. Higher is better.
What Is Sell-Through Rate?
Sell-through rate measures how fast your FBA inventory moves. Amazon calculates it as: Units Sold (90 days) ÷ Average Units in Stock (90 days). A rate of 3 means you sold 3x your average inventory over 90 days.
Why It Matters
Sell-through rate directly affects your IPI score. Low sell-through means excess inventory, higher storage fees, and potential capacity limits. Most sellers should aim for a sell-through rate above 2 to 4.
