EOQ What Is It, Examples, Formula, Relevance and Uses

It can be difficult to forecast the exact optimal number of stock to have on hand at your business and may result in cautious calculations that cause you to order smaller amounts. This under-ordering may cause inventory shortages, which can lose your business money. EOQ assumes constant demand and lead times, making it less effective in volatile markets or where demand fluctuates greatly. The EOQ may be too simple for the complex world of the supply chain. In my experience, many businesses struggle with order management basics. In that case, adding simple inventory principles can be a game-changer.

Limit 1: Unstable demand

The goal of the EOQ formula is to identify the optimal number of product units to order. If achieved, a company can minimize its costs for buying, delivering, and storing units. It assumes things like steady demand, consistent ordering costs, and holding costs that don’t change over time.

Extensions of the EOQ model

• While Economic Order Quantity (EOQ) is a valuable tool for optimizing inventory, it’s not a one-size-fits-all solution.
• For example, a popular item that was once in constant demand may fall out of style, or a business may need to ensure they have more Halloween costumes available for purchase in October.
• Ordering costs include things like processing fees, shipping charges, and staff time spent placing orders.
• Now that we have a basic understanding of what EOQ is, let’s explore why it’s so crucial in logistics.
• Manually updating EOQ values based on shifting inputs is time-consuming and prone to errors.

The EOQ calculator (economic order quantity) helps you find the optimal order you should place to minimize costs related to inventory, like holding and ordering costs. Please check out our ending inventory calculator to understand more. Economic order quantity is important because it helps companies manage their inventory efficiently. Without inventory management techniques such as these, companies will tend to hold too much inventory during periods of low demand while also holding too little inventory during periods of high demand. 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. If EOQ can help minimize the level of inventory, the cash savings can be used for some other business purpose or investment.

Why Is Economic Order Quantity Important For Business?

Economic Order Quantity (EOQ) gives the perfect standard quantity used by a company to calculate the inventory. It also helps in minimizing the total costs of inventory such as the overall ordering costs, shortage costs, and holding costs. EOQ itself does not directly account for lead time, but businesses must ensure they reorder when inventory levels reach the reorder point, calculated considering lead time to prevent stockouts.

Economic Order Quantity (EOQ): Definition and Formula

In today’s marketplace, optimization of resources, their adequate use, and cost reduction are the key attributes of a successfully developing company capable of competing effectively. For the qualitative analysis of available resources and the possibility of their optimal use in business practice, there is a large number of methods and models used depending on specific tasks. One of them is Economic Order Quantity (EOQ), which is a model used to determine the optimal expense definition quantity of goods or materials to be ordered at a given time in order to minimize the total cost of inventory. Thus, EOQ seeks to eliminate situations in which inventory builds up and instead offers tactics and methods to calculate and predict these quantities.

How do you calculate EOQ? The formula

Economic Order Quantity (EOQ) is the order size that minimizes the sum of ordering and holding costs related to raw materials or merchandise inventories. Keeping costs low will inflate margins and ultimately drive more revenue for the company. The Economic Order Quantity (EOQ) is an inventory management system that ensures a company orders the right amount of inventory that meets the demand for the product.

It’s like a universal tool that businesses of all shapes and sizes can use to save money and run smoother operations. An ERP/MRP system also facilitates the use of many other supply chain management techniques that are not so dependent on consistent demand. Annual demand is the number of products you expect to sell per year according to sales forecasts.

It helps to find a production volume or order that the company should add to minimize the holding cost and order cost. It is the ideal or the best quantity that the manufacturer will purchase that will be able to meet the consumer or business demand as well as remain within the optimum cost levels. By finding the EOQ, you can achieve a sweet spot where you order enough to avoid stockouts but not so much that your holding costs skyrocket.

• If the demand for your products fluctuates, using the EOQ will give you inaccurate results.
• Companies use warehouse inventory management software to help keep their holding costs low.
• Holding cost is the total costs a company incurs to hold inventory in a warehouse or store.
• Some systems, such as Lightspeed Retail’s POS system, will even let you set your desired inventory levels ahead of time.
• This is done in order to avoid stockouts and overstocking, thereby balancing inventory costs and opportunity costs.
• But if you order more than you can sell, you will start to rack up holding costs.

Economic Order Quantity helps in planning how much product to keep in stock for the number of sales made. It prevents the need to spend more and the risk of running low on stocks while demand persists. Examples of ordering costs include delivery charges, telephone charges, payment processing expenses, invoice verification expenses, and others.

It gives the best results concerning inventory which leads to better and long-lasting patronage.

By determining a reorder point, the business avoids running out of inventory and can continue to fill customer orders. 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. Whether you’re selling smartphones, building houses, or running a library, EOQ can help you manage your inventory smarter.
