In the below-given figure, we have shown the calculation for the EOQ for a pen manufacturing company. Let us understand the concept of economic order quantity equation with the help of a suitable example. To find EOQ – Economic Order Quantity Formula, differentiate total cost by Q. Annual holding cost is the sum of volume per order and holding cost, which can be written as. An annual ordering cost is the number of orders multiplied by ordering costs. As demand is constant, inventory will decrease with usage when it reduces to zero-order placed again.
This approach is also known as trial-and-error approach of determining economic order quantity. The economic order quantity is the level of quantity at which the combined ordering and holding cost is at the minimum level. In addition, you can always see what you have in stock and you can calculate your material requirements for upcoming orders. EOQ might not be great at predicting the weather, but it can handle seasonal changes in demand!
What is economic order quantity (EOQ)?
There are several ways to optimize inventory using the EOQ model, discussed in detail below. Take your learning and productivity to the next level with our Premium Templates.
As inventory costs are optimized, you may consider changes in the product’s price policy. The demand for your product throughout the year is 500,000 units. On average, you have to pay $4 for keeping one notepad in your inventory. Economic order quantity is important because it helps companies manage their inventory efficiently.

Economic order quantity is a supply chain management technique used to determine the optimal lot size per order. This is done in order to avoid stockouts and overstocking, thereby balancing inventory costs and opportunity costs. Calculating the EOQ on each item will give you the optimal reorder point, meaning when the item’s inventory falls to a specific number, it’s time to reorder. As different vendors have unique production and shipping times, each item may have a different reorder point.
If a company is constantly placing small orders to maintain a specific inventory level, the ordering costs are higher, and there is a need for additional storage space. The Economic Order Quantity is a set point designed to help companies minimize the cost of ordering and holding inventory. The cost of ordering inventory falls with the increase in ordering volume due to purchasing on economies of scale. However, as the size of inventory grows, the cost of holding the inventory rises. EOQ is the exact point that minimizes both of these inversely related costs.
- The concept of economic order quantity equation helps in cash flow management by bringing a balance in the quantity of orders and funds required for the same.
- Economic order quantity is a supply chain management technique used to determine the optimal lot size per order.

Further, we will calculate holding, ordering, and the number of orders per year and combine ordering and holding costs at economic order quantity. 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. The required parameters to the solution are the total demand for the year, the purchase cost for each item, the fixed cost to place the order for a single item and the storage cost for each item per year. Note that the number of times an order is placed will also affect the total cost, though this number can be determined from the other parameters. 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.
Ordering is the cost of placing an order to the supplier for inventory. The annual quantity calculates the number of orders demanded divided by the volume per order. The process of calculating EOQ can be either computerised of manual. The formula is such that it will automatically trigger the requirement to place further order immediately to avoid shock shortage, else it will lead to loss of revenue and customer base. The formula can help a company control the amount of cash tied up in the inventory balance.

#1 – Holding Cost
Keeping safety stock on hand is a good idea, as it can help you avoid unhappy customers if you run out of the item they want due to supplier delays, unexpected demand, or an inaccurate inventory forecast. In this example, assuming demand remains constant over time, the optimal quantity of hats to minimize your order costs while meeting demand would be master budget approximately 490 units. Compute EOQ, when a retail store sells 20,000 units of a certain product annually. The cost to place and process each order is $50, and the holding cost per unit per year is $2.
- Too low quantity will result in loss of sales and too high will lead to blocking of funds that can be used for other more useful investments and areas of business.
- As the company manufactures hardwood furniture, inventory does not depreciate.
- Calculate the economic order quantity i.e. the optimal order size, total orders required during a year, total carrying cost and total ordering cost for the year.
- If achieved, a company can minimize its costs for buying, delivering, and storing units.
Businesses use the EOQ formula to help them reduce their overall inventory costs. Calculate the economic order quantity i.e. the optimal order size, total orders required during a year, total carrying cost and total ordering cost for the year. Instead of focusing on ordering costs or carrying costs individually, a company should attempt to reduce the sum of these costs. When you use economic order quantity (EOQ), you eliminate the need for guesswork as you order stock, and ensure you don’t over-order or run out too quickly. The EOQ formula is data-driven, and when combined with expense and inventory management software, makes it simple to stay on top of your company’s inventory needs. In many businesses, the amount of ordering can change based on the season, how much a product costs up the supply chain, whether a vendor offers a discount, whether consumer demand remains steady, and other factors.
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. 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.

A manufacturing company produces a particular component used in electronic devices. They estimate their annual demand for this component what is an invoice example and template to be 10,000 units (D). The ordering cost per order is $200 (S), and the holding cost per unit per year is $10 (H). As mentioned above, your safety stock is the amount of product you keep on hand, above what you believe will sell, to ensure you don’t run out between orders. A safety stock assessment involves analyzing the time it takes for the product to arrive from the vendor, the average demand for the product, your supply chain configuration, and your comfort level with running low.
