Economic Order Quantity Formula: How to Calculate EOQ

For example, a company could decrease inventory space for products that aren’t selling while increasing inventory space for products that are. A company can optimize the costs related to the space and maximize staff efficiency. It also helps determine the operating cash flow necessary to keep the business running. This model is valuable for a small business owner since it can reduce overhead costs. EOQ supply chain management generally only works if demand for a product remains constant over a long period.

  • The EOQ tells you how much of a product you should order, so you can easily use that number when manually creating purchase orders in your POS system, if it has that functionality.
  • The EOQ formula determines the inventory reorder point of a company.
  • If there’s a change in any of your inventory costs, you can always tweak the formula and generate a new EOQ to suit the current conditions.

Order Cost Calculation (S)

Economic Order Quantity is valuable to both small and big business owners. It assists managers in taking decisions on the number of times they make orders on a particular item, how often they reorder to get low possible costs and how much inventory they have.

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. It gives the best results concerning inventory which leads to better and long-lasting patronage. Identifying the optimal number of products to order is the main purpose of the Economic Order Quantity (EOQ).

How To Identify the Optimal Number of Products

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. 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. Manufacturing costs can likewise fluctuate based on time of year, turnaround rate, and more. The formula also doesn’t take extra costs into account—like setup costs on inventory orders for brand new products.

The Formula for Economic Order Quantity

The EOQ formula is one of several inventory calculations that small businesses can use to make their inventory management workflows more efficient. When you run your inventory at maximum efficiency, your business runs better as a whole. You’re able to meet customer demand more efficiently, determine better when to reorder, and know how much inventory to hold. An EOQ model helps an inventory manager determine when products should be reordered, restocking inventory only when it drops to a certain point. It determines the optimal quantity of EOQ inventory to reorder, and it reduces the risk of shortages or excess inventory.

Holding inventory can be one of the most expensive aspects of ecommerce fulfillment. It’s expensive to manufacture or procure and it is expensive to keep in stock. Whether it is raw materials, work in process (WIP) or finished goods, companies can use EOQ as an efficient ordering guideline to prevent shortages while not maintaining excess inventories.

Design of optimal quantity discount schedules

An e-commerce retailer might place regular orders for a favorite consumer item, X. The retailer needs to think about total inventory costs, including the purchase cost for that unit, quantity discounts, ordering costs, shipping costs, holding cost, and storage costs.

The EOQ helps companies minimize the cost of ordering and holding inventory. As explained by the economic concept known as economies of scale, the cost per unit of ordering a product falls, the larger the total quantity of the order. However, the larger the total quantity of an order, the higher the cost to hold and carry your inventory. Economic Order Quantity assumes both the ordering and holding costs are constant. Therefore, making it impossible to account for other factors that can affect the ordering and holding costs. Ordering the optimal number of products needed helps the company to keep its costs low and prevent dead stocks.

A larger order-quantity reduces ordering frequency, and, hence ordering cost/ month, but requires holding a larger average inventory, which increases storage (holding) cost/month. On the other hand, a smaller order-quantity reduces average inventory but requires more frequent ordering and higher ordering cost/month. The cost- minimizing order-quantity is called the Economic Order Quantity (EOQ). This chapter also provides intuition about choosing an inventory-management system, not just an EOQ. In many cases, you can incorporate the EOQ of a product into a point-of-sale system.

The EOQ formula shouldn’t be taken as gospel, but it’s a useful tool for informed, effective inventory control. Economic Order Quantity (EOQ) is derived from a formula that consists of annual demand, holding cost, and order cost. This formula aims at striking a balance between the amount you sell and the amount you spend to manage your inventory. The economic order-quantity model considers the tradeoff between ordering cost and storage cost in choosing the quantity to use in replenishing item inventories.
