Also, as the number of orders decreases, the ordering cost decreases but the holding cost increases. Examples of holding costs include insurance and property tax, rent, deterioration, maintenance fees, storage space, shrinkage, obsolescence, and others. Ordering costs refer to all the costs incurred each time an order is placed for inventory with the company. The EOQ assumes demand is constant and inventory is reduced at a fixed rate until it reaches zero.
What Is Economic Order Quantity?
Businesses operate better when they are aware of their ideal Economic Order Quantity. Economic Order Quantity helps a business time its orders for inventory to avoid low stocks and dead stocks situations. 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.

EOQ Formula with examples in Excel (Economic Order Quantity)
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. This allows the company to make strides towards being as cost-efficient as possible while ensuring that production and sales continuity is guaranteed. Without it, companies will tend to hold too much inventory during periods of low demand, while also holding too little inventory in periods of high demand.
Key takeaways
- The EOQ is the size of the order that yields the best economy when purchasing any material.
- When an equation is vaguely introduced it can be hard to understand its meaning and utility.
- In essence, EOQ is a tool used to determine the volume and frequency of orders required to satisfy a given level of demand while minimizing the cost per order.
- When dealing with very small figures, EOQ may be too simplistic – useful more as an ‘average scenario’ indicator than a reliable figure.
- In other words, it is the optimal inventory size that should be ordered with the supplier to minimize the total annual inventory cost of the business.
This basic formula can save businesses thousands of dollars as it prevents you from overspending on inventory costs. The economic order quantity formula takes into account multiple factors to bring down total costs and gives you insights into managing inventory. To calculate the EOQ for inventory you must know the setup costs, demand rate, and holding costs. By placing a large batch order at once, you would be able to save on your setup cost.

On the other hand, carrying costs, which are variable or semi-variable in nature, tend to change nearly in direct proportion to the level of stock carried in a manufacturing firm. The Economic Order Quantity (EOQ) is the specific total order amount for a firm’s inventory that minimizes the total cost of inventory management. Ordering cost is inversely proportional to holding cost if the annual demand remains constant. As the number of orders increases, the ordering cost increases but the holding cost decreases.
The amount of money spent on inventory storage becomes lesser and more affordable. 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. Keep your inventory turnover optimized and cut costs to increase your company’s profitability! In the example above, we have a rate of 9.5% of the purchase price or 2.85€. In concrete terms, the cost of ownership of a product costing €30 over a year would be €2.85.
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. Assume, for example, a retail clothing shop carries a line of men’s jeans, and the shop sells 1,000 pairs of jeans each year.
He incurs a setup cost of $100 (S) and a holding fee (H) of $16 per shirt. Carrying cost is calculated based on the insurance premium, depreciation, obsolescence, storage, preservation costs, and interest on value of stock held, including https://www.simple-accounting.org/ that of handling and other allied costs. For a single order, the procurement cost is the total cost, which is obtained by adding up all the above costs and dividing the result by the number of orders placed during that period.
It can aid in the staff knowing what needs to be done so they are better prepared and work better. With the overwhelming number of orders every single day, businesses that perform their own deliveries find it hard to save time or money during the process. Even if you have low-demand deliveries it sure would be helpful to make it as efficient as possible. If you run your own warehouse then this is great news as you will be able to more efficiently manage it due to the lesser stock.
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 unit cost includes the raw material, shipping and handling and all of the expenses that went into the item- otherwise known as setup cost. In many cases, you can incorporate the EOQ of a product into a point-of-sale system. The EOQ formula is one of several inventory calculations that small businesses can use to make their inventory management workflows more efficient. To determine the procurement cost of multi-item orders, the total cost is divided by the number of items ordered during a given period of time. On the other hand, purchasing in small quantities implies high purchasing or acquisition costs and low carrying costs.
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. The advantages of EOQ include reduced ordering and holding costs, while disadvantages include assumptions that may not match real-life conditions. Economic order quantity (EOQ) is a formula used to determine the optimal order quantity that balances the cost of ordering and holding inventory. So a business would see it needs to reorder new materials soon based on its EOQ figure, but usually it’s not able to purchase less than the MOQ set by the company from which it makes that order.
But if you order more than you can sell, you will start to rack up holding costs. Businesses use the EOQ formula to help them reduce their overall inventory costs. If an item doesn’t have a known carrying cost, then the eoq calculation can be modified. The total annual requirement divided by the unit production costs will provide some insight on how many units should be ordered at once to avoid excessive ordering costs.
With sufficient inventory levels, you can really make an impact on the inventory management process. The supply chain is notorious for getting cluttered quickly which is why it is best if a business can keep its inventory limited and organized. The Economic Order Quantity (EOQ) formula helps to avoid these mis-stocking situations.
While there is no foolproof way to accurately predict annual demand, your sales from the previous year can be an indicator of sales in the current year. Consider calculating an overall average to estimate how much stock you need to meet the customer demand. Economic Order Quantity may not consider all the factors that affect each business, but it is still a powerful tool to help an entrepreneur or manager to make more calculated decisions. What makes the EOQ a compelling tool is that it is dynamic and can be revisited from time to time as your business grows. 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. Economic Order Quantity (EOQ) is derived from a formula that consists of annual demand, holding cost, and order cost.
