What is the Reorder Point (ROP)?

When you stock an item in demand, every purchase reduces your inventory levels. The inventory Reorder Point is the formula that allows you to reorder stock at the correct time. Having a system in place to deal with your Reorder Point can reduce costs, but it can also remove the stress from ordering inventory.

You need to order fresh stock before you run out, but if it is too early you will increase holding costs. If it is too late, you run the risk of stock-outs, which may send your customers to the competition.

How do you know when it is time? Safety stock is stocked to give you time to place new purchase orders. You can work out your safety stock levels by multiplying your average daily usage and lead time in days.

Average lead time gives you a good indication as to how long you will need to wait for new stock because you need a sufficient amount of stock to meet customer demand in the meantime. Safety stock provides you with a buffer in case of supply chain issues, depending on the number of days it takes to receive stock. 

How to calculate the Reorder Point (ROP)

You can calculate the Reorder Point for your business by using the Reorder Point formula.

Lead time demand + Safety Stock Level = Reorder Level
