EOQ – Definition & Assumptions of Economic Order Quantity

If a company is constantly placing small orders to maintain a specific inventory level, the ordering costs are higher, and there is a need for additional storage space. Also referred to as ‘setup cost,’ how much does an order cost per purchase? This is done on a per-order basis and includes both the shipping and handling costs. You may think of EOQ not only as a useful model to manage your inventory, but also as a way to manage your company’s cash flow. There are many companies for which inventory costs significantly impact their balance sheet.

Economic order quantity 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. This production-scheduling model was developed in 1913 by Ford W. Harris and has been refined over time. The economic order quantity formula assumes that demand, ordering, and holding costs all remain constant.

  • EOQ is necessarily used in inventory management, which is the oversight of the ordering, storing, and use of a company’s inventory.
  • This is so a company does not have to make orders too frequently and there is not an excess of inventory sitting on hand.
  • At the same time, EOQ has some key limitations that mean it’s not a formula every business can use – we lay out its advantages and disadvantages below.

Additionally, the demand for this inventory will also be realized as not to make a business suffer a shortage. Thus by ordering 2,263 units, QRS will improve efficiency by cutting inventory costs without negatively impacting the manufacturing process. If there is overstocking, products that are not yet sold are holding warehouse space for a long time.

Disadvantages of the EOQ model

Usually, inventories go through a conversion process before coming to their finished form. In some cases, however, companies may sell products as acquired from suppliers. Either way, inventories represent the primary income source for companies that deal in physical stock. Both EOQ and EPQ are a way of predicting inventory requirements to reduce costs and prevent stockouts. With these limitations in mind, EOQ tends to work best with scale.

Assumptions EOQ and EPQ Models

The total holding costs depend on the size of the order placed for inventory. Firstly, it focuses on minimizing inventory costs for companies. It is a critical part of inventory management from which companies can benefit. Similarly, it considers the demand for products, which can play a substantial role in avoiding stockouts.

Ordering costs refer to all the costs incurred each time an order is placed for inventory with the company. Businesses operate better when they are aware of their ideal Economic Order Quantity. Economic Order Quantity helps a business time its orders for inventory to avoid low stocks and dead stocks situations. Economic Order Quantity is valuable to both small and big business owners.
