If the company runs out of inventory, there is a shortage cost, which is the revenue lost because the company has insufficient inventory to fill an order. An inventory shortage may also mean the company loses the customer or the client will order less in the future.

Additionally, the EOQ model reduces the chance of inventory shortages which can lead to unrealized losses.

Economic order quantity (EOQ) is the ideal quantity of units a company should purchase to meet demand while minimizing inventory costs such as holding costs, shortage costs, and order costs.

We can determine monthly demand for raw materials by multiplying the annual forecast by 12.
