Examples of ordering costs include delivery charges, telephone charges, payment processing expenses, invoice verification expenses, and others. Economic Order Quantity also provides an ideal method of calculating the appropriate reorder point and the optimal reorder quantity to prevent shortages in inventory by replenishing the inventory instantly. Economic Order Quantity (EOC) is the quantity required to avoid running out of stocks. There are times when demand can increase suddenly or there are issues with a supplier that can prevent you from having enough inventory. Safety stock is also often used during busy shopping seasons like the holidays or during a big promotion or flash sale. EOQ is calculated on a per-product basis – in other words, one product’s EOQ may not be the same as a different product’s EOQ.
Harold Averkamp (CPA, MBA) has worked as a university accounting instructor, accountant, and consultant for more than 25 years.

Determination of Economic Order Quantity (EOQ) does not put a delay in delivery time into consideration. It gives the best results concerning inventory which leads to better and long-lasting patronage.
- Economic order quantity is a calculation companies use to figure out the optimal number of inventory units to order, with the goal to minimize the logistics costs, warehousing space, stockouts, and overstock costs.
- Businesses operate better when they are aware of their ideal Economic Order Quantity.
- Other variations of Q/Q are month over month (M/M) and year-over-year (YOY).
- You also avoid the opposite situation, where you overstock during a period of low demand, leading to potential spoilage or – at the very least – needlessly high holding costs.
This makes it much easier for your brand to scale its inventory, fulfillment, and shipping operations, both into new channels and into new demographics and global locations. By calculating how much inventory you need on how much you are planning to sell, EOQ will help you avoid stock-outs without having too much inventory on hand for too long. It can definitely be surprising enough to see that ordering in small quantities can be way more cost-effective, but this can turn the other way as well – calculating EOQ for your products can help. 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.
You can check inventory counts in real-time, set automatic reorder points, and better forecast demand.

Investing in an inventory management software or partnering with a 3PL) makes this easy to do.

Demand rate is a key element in the EOQ formula – but anyone who runs an ecommerce brand knows that demand doesn’t always turn out the way you initially expect it to. If demand for your products suddenly skyrockets or plummets, using the economic order quantity that you previously calculated may lead to you purchase too much or too little inventory. By calculating how much you need based on how much you sell in a given period of time, you can also avoid stockouts without keeping too much inventory on hand for too long.
Economic order quantity vs. minimum order quantity (MOQ)
In situations where the EOQ is not a whole number, it predicts the number of units you should order to minimize your holding and order costs. Minimizing the holding costs the ultimate guide to group buying sites to the barest minimum is an important aspect of warehouse management. Companies use warehouse inventory management software to help keep their holding costs low.
Why Is Economic Order Quantity Important?
Many POS systems allow you to set reorder points, or inventory thresholds that indicate when to order more stock. When your product inventory levels reach their reorder points, you’ll be prompted to place another order. The application of tabular approach is not common as it is more time consuming as compared to formula approach.
The goal of calculating the Economic Order Quantity (EOQ) is to identify the optimal number of product units to order. By arriving at an optimal number of products to order, the company can minimize the costs for the buying, delivery, and storage of items. It reduces the likelihood of a company having excess inventory in its warehouse or store. Too much inventory means that the company is taking on unnecessary holding costs while also running the risk of increased costs due to damaged goods. On the other hand, too little inventory can lead to stock-outs which will cause you to lose sales. Having to reorder goods frequently also racks up transportation costs.By calculating EOQ, a business can determine when an order is to be placed and how much is to be ordered.

Perhaps you’ll discover that ordering in smaller quantities is more cost-effective for your business, or perhaps it’s cheaper to order in bulk. Having extra items in your inventory can quickly increase storage costs. Inventory costs can also go up depending on how you order, what gets damaged, and what products never sell. If you’re constantly re-ordering products that have low velocity, EOQ can help determine how much to order in a certain time period. Critics have argued that the assumptions of constant demand and fixed cost levels are a limitation of the EOQ model.
When a business orders less inventory than its customers demand, it can easily lose out on customers who will go elsewhere for the product. Other variations of Q/Q are month over month (M/M) and year-over-year (YOY). The month over month measures growth over previous months but tends to be more volatile than Q/Q as the rate of change is affected by one-time events, such as natural disasters. The YOY measures changes in performance in one year over the previous year. YOY incorporates more data and thus provides a better long-term picture of the underlying report figure. The Q/Q rate of change is typically more volatile than the YOY measurement but less volatile than the M/M figure.
There is an inverse relationship between ordering cost and holding cost. Keeping the annual demand constant if for example the number of orders decreases, the ordering cost will also decrease but the holding cost will rise and vice versa. The economic order quantity is the level of quantity at which the combined ordering and holding https://simple-accounting.org/ cost is at the minimum level. 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.

Although the EOQ formulation is straightforward, factors such as transportation rates and quantity discounts factor into its real-world application. The economic order quantity (EOQ) refers to the ideal order quantity a company should purchase in order to minimize its inventory costs, such as holding costs, shortage costs, and order costs. EOQ is necessarily used in inventory management, which is the oversight of the ordering, storing, and use of a company’s inventory. Inventory management is tasked with calculating the number of units a company should add to its inventory with each batch order to reduce the total costs of its inventory. The economic order quantity formula assumes consistent demand, fixed costs, and the absence of other external factors that may impact demand, holding costs, or setup costs.
A person or company with numerous litigation problems has a higher underwriting risk and is likely to find E&O insurance more expensive or less favorable in its terms as a result. On average, E&O insurance can run around $500 – $1,000 per employee, per year. E&O insurance is also applicable to businesses outside the financial industry including nonprofits, general maintenance companies and contractors, and engineering firms.

Economic Order Quantity (EOQ) is the order size that minimizes the sum of ordering and holding costs related to raw materials or merchandise inventories.
