It also helps in minimizing the total costs of inventory such as the overall ordering costs, shortage costs, and holding costs. The eoq formula is derived by solving for q, which equals total annual order cost divided by the unit production cost. It takes into account per-unit ordering costs and holding costs per year. Ordering a large amount of inventory increases a company’s holding costs while ordering smaller amounts of inventory more frequently increases a company’s setup costs. The EOQ model finds the quantity that minimizes both types of costs.
Assumption of Constant Ordering and Holding Costs
One of the important limitations of the economic order quantity is that it assumes the demand for the company’s products is constant over time. EOQ applies only when demand for a product is constant over a period of time (such as a year) and each new order is delivered in full when inventory reaches zero. There is a fixed cost for each order placed, regardless of the quantity of items ordered; an order is assumed to contain only one type of inventory item. There is also a cost for each unit held in storage, commonly known as holding cost, sometimes expressed as a percentage of the purchase cost of the item. Although the EOQ formulation is straightforward, factors such as transportation rates and quantity discounts factor into its real-world application.
EOQ is the exact point that minimizes both of these inversely related costs. The goal of the EOQ formula is to identify the optimal number of product units to order. If achieved, a company can what is a pay raise at work minimize its costs for buying, delivering, and storing units.

In cases where the usage of materials or products is unpredictable, the formula becomes useless. The Economic Order Quantity formula only works when the holding costs, ordering costs, and annual demand is predictable. Economic order quantity will be higher if the company’s setup costs or product demand increases. On the other hand, it will be lower if the company’s holding costs increase. The total inventory cost is the ordering cost plus the carrying cost. It is necessary to minimize total inventory costs, and the EOQ concept is ideal in helping to achieve this.
Holding cost is the total costs a company incurs to hold inventory in a warehouse or store. The total holding costs depend on the size of the order placed for inventory. For companies involved in manufacturing or consumer sales, inventory management is key to controlling operating costs. The economic order quantity model allows companies to find the right balance between storing unused products and making new orders, allowing them to minimize inventory costs. Economic Order Quantity (EOQ) gives the perfect standard quantity used by a company to calculate the inventory.

For a single order, the procurement cost is the total cost, which is obtained by adding up all the above costs and dividing the result by the number of orders placed during that period. The salaries of the personnel involved in all business processes are the main items to be considered when calculating the procurement cost. The concept of EOQ relates to the quantity of materials that a purchasing department aims to procure. That is to say, EOQ refers to the size of the order that gives the maximum economy when purchasing any material.
The cost of obtaining quotations, preparing/placing orders, conducting follow-up actions, receiving and inspecting, and paying bills are all included in the procurement cost. The EOQ is the size of the order that yields the best economy when purchasing any material. The EOQ assumes the lowest level at which stock can be reduced to is zero. Determination of Economic Order Quantity (EOQ) does not put a delay in delivery time into consideration. Although Economic Order Quantity is efficient, it can only function in situations where demands are constant. In situations where the demand is not consistent, the Economic Order Quantity (EOQ) will provide a misleading figure.
How to Use EOQ – Example 1
Material acquisition costs arise on account of having to process an order. Part of the wages and operating expenses for departments such as production control, purchasing, receiving, and storage are incurred for purchasing and possessing the materials. Ordering the optimal number of selling expense budget products needed helps the company to keep its costs low and prevent dead stocks. 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. Let’s take an example to calculate EOQ – Economic Order Quantity for a pen manufacturing company where the company’s annual quantity demanded is 400, the holding cost is $2, and the ordering cost is $1. This concept arises from the fact that the cost remains under control but the required demand is met.
