What Is the Economic Order Quantity? EOQ Formula, Calculator, Example

The economic order quantity is the level of quantity at which the combined ordering and holding cost is at the minimum level. It is always good practice to reduce your costs as much as possible to maximize your profits. Read the next sections to find out more about what is EOQ, how to use the simple EOQ formula, and what the EOQ meaning is to improve your inventory management. Malakooti (2013)10 has introduced the multi-criteria EOQ models where the criteria could be minimizing the total cost, Order quantity (inventory), and Shortages. Perera et al. (2017)4 establish this optimality and fully characterize the (s,S) optimality within the EOQ setting under general cost structures.

Backordering costs and multiple items

The EOQ could potentially lead to shortages, and may not be the best way to calculate your order size if business is booming. Newly launched products may have higher demand in the beginning that decreases over time. Products with seasonal demand — in which sales fluctuate throughout the year — could invalidate EOQ calculations. You can’t simply measure EOQ at the beginning of the year and expect it to hold true. This could lead to periods of stockouts or excess inventory because of inconsistent reordering. Having too much inventory results in higher costs that take away from profits due to the cost of maintaining inventory and sometimes having to discard old inventory.

• Our partners cannot pay us to guarantee favorable reviews of their products or services.

The Economic Order Quantity (EOQ) formula is a powerful tool for businesses to optimize their inventory management and reduce costs. By understanding the formula and its components, businesses can make informed decisions to improve their supply chain efficiency. While the EOQ formula has certain limitations, its successful implementation in various industries showcases its value. As the field of inventory management continues to evolve, the EOQ formula remains a cornerstone for effective inventory control. You probably noticed that some of the variables require information on an annual timeline. That’s because the EOQ formula makes certain assumptions that demand, setup costs, holding costs and goods prices are always constant.

POS systems, such as QuickBooks Desktop Point of Sale, can use reorder points to automate purchase order forms for you, which makes it simple for you to use the EOQ. Some systems, such as Lightspeed Retail’s POS system, will even let you set your desired inventory levels ahead of time. Fortunately, this problem complete collar colors is easily solved if you calculate a safe reorder point that takes your supply chain and manufacturer’s lead time into consideration.

If the cost per item is different every time you order, then the EOQ formula’s assumption of consistent production costs can be a massive thorn in your side. So let’s say you run a construction company, and you’re trying to figure out the best way to balance inventory costs for your supply of cement (purchased in bags). You usually use around 15, pound bags of concrete per year, and each bag costs $4 to order—plus a $100 order fee from the manufacturer on every order.

Under tabular approach of determining economic order quantity, the combined ordering and holding cost is computed at different number of orders and their respective order quantities. This approach is also known as trial-and-error approach of determining economic order quantity. Based on the provided information, we have calculated that you should order 1,581 units to keep your inventory costs at their lowest. As inventory costs are optimized, you may consider changes in the product’s price policy. Using the EOQ for inventory planning can help you meet demand while maintaining a reasonable inventory balance.

That will, in turn, drive up your inventory costs since you’re paying extra to store items that aren’t selling.

You’ll know exactly how much product will be ordered at certain inventory levels. The EOQ formula is the square root of (2 x 1,000 pairs x $2 order cost) / ($5 holding cost) or 28.3 with rounding. The ideal order size to minimize costs and meet customer demand is slightly more than 28 pairs of jeans. A more complex portion of the EOQ formula provides the reorder point. The goal of the EOQ formula is to identify the optimal number of product units to order.
