What is Reorder Point? Reorder Point Definition & Formula

A fixed reorder point system is a method of inventory management that uses a constant value for the reorder point. This means that whenever the inventory level reaches or falls below this value, a new order is placed for a fixed quantity. The reorder point is usually calculated based on the average demand and the lead time, which are the time between placing and receiving an order. The fixed reorder point system is easy to implement and understand, and it works well for stable and predictable demand patterns.

Establishing reorder points frees up crucial capital and ensures your business is operating at maximum efficiency across inbound and outbound logistics.

Calculating basic safety stock is quite a straightforward affair that involves multiplying the average demand for items with a preset value of safety days.

Safety stock is the amount of inventory a business holds to mitigate the risk of shortages or stockouts. The safety stock calculation is the difference between the maximum daily sales/usage and lead time, and the average daily usage and lead time.

The safety stock level is the minimum number of units a company needs to have in stock to fill sales orders or meet production targets. Once inventory dips below the calculated reorder point, replenishment is triggered through a new purchase order.
