The Economic Order Quantity(EOQ) is the number of items that a business should add to inventory with each order to minimize inventory carrying costs. While ROP determines the lowest stock level, EOQ is used to determine the size of the order. Depending on where a business sets its reorder point, the ROP can be greater than EOQ.
