Economic Order Quantity (EOQ)
Candlefocus EditorThe EOQ equation was originally developed by Ford W. Harris in 1913, but the formula was further refined in the 1920s by engineers working at the US Army’s Ordnance Department. The basic EOQ equation takes into account four main factors that affect the optimal order quantity: the demand for a product, the ordering cost of a product, the carrying cost of inventory, and the annual demand for the product. The formula can be used to determine the cost-minimizing unit of goods for any given product or service by weighing the benefits and the costs associated with ordering and holding inventory.
The EOQ equation enables businesses to determine the most optimal order quantity of goods required to meet demand while minimizing costs. By doing so, businesses can ensure there is not too much or too little inventory stock, thus mitigating the risk of financial losses. Calculating the EOQ also permits a company to make more informed decisions on factors such as supplier selection, product differentiation, and price optimization.
In setting the economic order quantity, a company should take into account the fixed and variable costs associated with ordering, carrying, and holding inventory. For instance, a business’s ordering costs may include transport costs, shipping fees, and supplier costs, and their inventory carrying costs may include storage space, shelf space, and lost opportunity costs. Additionally, businesses should also consider the cost of misplaced, damaged, and obsolete inventory, as this can have a major impact on the ultimate decision to adjust their EOQ.
Ultimately, the economic order quantity is an essential tool for businesses looking to save money by optimizing their inventory but it is important to note that it only works when all other factors are held constant over time. By taking these costs into account, businesses can successfully utilize the EOQ model to make best use of their inventory and save costs in order to remain competitive in their respective markets.
