Amazon offers multiple statistics as Inventory Performance Index (IPI) that primarily give you an overview of your activity as a Seller on Amazon.
One of these IPIs is the Sell-through rate visible on the Seller Central dashboard. This statistic is updated daily on Seller Central dashboard.
The formula for calculating it is as follows:
Sell-through rate= Total units shipped in past 90 days/ Avg. units in inventory during the same period.
(Inventory levels snapshots are taken today, 30 days ago, 60 days ago, and 90 days ago. A mean average of all 4 is used in the above formula for calculating sell-through rate)
Ex: If 40 units shipped, and you had 80 units available, the sell-through rate would be 40/80= 0.5 i.e. 50%.
As this is an important metric for you to analyze your activity as a Seller, we've added this information on the Accelerlist Dashboard:
As it is based on your recent activity, you'd see the Sell Through Rate vary accordingly:

(Note: Sell-through rate accounts units sold and shipped, not just sold. Whereas Sales Metric in Seller Central simply counts orders, not units shipped. )

If you're looking to improve your Sell-through rate, you'd basically need to reprice your products competitively so that buyers are more probable to choose your listing. Our own repricer: Profit Reprice™ can certainly help in automating the repricing process, and optimizing your profits. :)
