What is Reorder Point and Reorder Point Formula?

Lead times can vary due to factors like shipping delays or supplier issues.

Lead time refers to the amount of time it takes for your supplier to process, ship, and deliver the product after you place an order. The longer the lead time, the more inventory you’ll need to carry to avoid stockouts. To calculate your demand average, choose a time period, determine how much product you sell in that time period, add up your units, and divide by the number of days in the time period.
