You can check inventory counts at each fulfillment center and set automatic reorder levels, so you are notified when stock is running low. So now you know the reorder point formula, but you might be wondering – what is demand during lead time? In this section we break down ROP and tell you exactly how to calculate it.

Video Introduction: The Definition of Reorder Point
And let’s assume that the average daily use is 1.5 units, and the average lead time is 12 days. The reorder point calculation takes into account delivery lead time from suppliers. By keeping track of average delivery lead time, you can identify your most reliable and least reliable suppliers and make more informed procurement decisions. This method simply calculates the average amount of inventory that is used over a period of time and orders that quantity when inventory levels reach a certain point.
