For example, if you run out of inventory, there’s a shortage cost, which equals revenue loss because you can’t fill orders. If EOQ can minimize inventory levels and lower holding costs while keeping stock constantly available, the extra cash can be used in areas like product development or marketing. Calculating the EOQ on each item will give you the optimal reorder point, meaning when the item’s inventory falls to a specific number, it’s time to reorder.
Get started by checking out our top-recommended inventory management platforms. The biggest failing of the EOQ model is it assumes production costs and storage costs for your product are constant. On the one hand, you want to take advantage of economies of scale (a.k.a. the savings available when you order a higher quantity of items at once). But on the other hand, ordering tons of items at once ramps up the storage costs for your inventory. When you calculate EOQ, you know the ideal order size to maximize profits for your organization. It prevents guessing, and there’s less cause for concern about overordering or running out of stock.
Carrying costs represent costs incurred on holding inventory in hand. These include opportunity cost of money held-up in inventories, storage costs such as warehouse rent, insurance, spoilage costs, etc. EOQ uses a formula to determine the most advantageous amount of stock for a business to order.

That will, in turn, drive up your inventory costs since you’re paying extra to store items that aren’t selling. They have historical data showing that they sell an average of 500 smartphones per month (demand rate, D). Each time they place an order with the supplier, they incur ordering costs of $100 (ordering cost per order, S). Additionally, the holding cost per smartphone per year is $5 (holding cost per unit per year, H). This makes it hard, or nearly impossible, for businesses to account for changes in consumer demand or seasonality. If you don’t have correct, real-time data on holding or order costs, you’ll have the wrong amount of inventory, which can quickly lead to a stockout.
For example, a business owner becomes aware of the risk of over-stocking if he or she decides to order a certain amount of new stocks at a particular time. Economic Order Quantity shows business owners if current order quantities are reasonable or not. It helps to indicate if an action should or should not be carried out. One of the biggest problems that affect the profitability of a business is balancing its inventory orders with the demand for the inventory in the marketplace.
What Is Economic Order Quantity – EOQ?
While at first glance over-ordering may seem like a safer move, you may be tying up too much of your cash in physical stock during periods of low demand. The EOQ formula determines the inventory reorder point of a company. When inventory falls to a certain level, the EOQ formula, if applied to business processes, triggers the need to place an order for more units.

Economic Order Quantity (EOQ) : Meaning, Working, Formula and Examples
The Economic Order Quantity is used by manufacturing and merchandise companies. The merchandise companies compute it to get the optimal order size of ready-to-use merchandise inventory while the manufacturing companies compute it to find the optimal order size of raw materials inventory. Ordering the optimal number of products needed helps the company to keep its costs low and prevent dead stocks.
Downsides of the economic order quantity model
By calculating the optimal order quantity of each item, you will be more likely to sell it well before its best-by date. EOQ takes into account the timing of reordering, the cost incurred to place an order, and the cost to store merchandise. 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. For many companies, inventory is its largest asset other than its human resources, and these businesses must carry sufficient inventory to meet the needs of customers. Economic order quantity (EOQ) is a replenishment model designed to help you minimize your inventory costs, and overall, improve your inventory and supply chain management.

Using the EOQ for inventory planning can help you meet demand while maintaining a reasonable inventory balance.

The aim of calculating the Economic Order Quantity is to determine the number of inventory to be attached to each order at the lowest possible costs. Ordering cost is inversely proportional to holding cost if the annual demand remains constant. As the number of orders increases, the ordering cost increases but the holding cost decreases. Also, as the number of orders public accounting vs private accounting decreases, the ordering cost decreases but the holding cost increases.
