EOQ Formula and Guide to Economic Ordering Quantity

  • by

The company’s reputation and profitability are always at stake if it has too much or too little inventory on hand. 43% of business owners have considered “overbuying inventory” as a challenge, whereas 36% said the same for “underbuying inventory”. 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. The salaries of the personnel involved in all business processes are the main items to be considered when calculating the procurement cost. That is to say, EOQ refers to the size of the order that gives the maximum economy when purchasing any material.

  1. Examples of holding costs include insurance and property tax, rent, deterioration, maintenance fees, storage space, shrinkage, obsolescence, and others.
  2. The EOQ formula is one of several inventory calculations that small businesses can use to make their inventory management workflows more efficient.
  3. Carrying cost is calculated based on the insurance premium, depreciation, obsolescence, storage, preservation costs, and interest on value of stock held, including that of handling and other allied costs.
  4. The economic order quantity is the level of quantity at which the combined ordering and holding cost is at the minimum level.

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.

The assumptions described above are also known as the limitations of economic order quantity (EOQ). The EOQ assumes the lowest level at which stock can be reduced to is zero. 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.

Calculating the economic order quantity (EOQ) for your business can help you to analyze better, order better, and eventually have better profit margins.

Other names used for economic order quantity are optimal order size and optimal order quantity. Economic order quantity is an inventory management technique that helps make efficient inventory management decisions. It refers to the optimal amount of inventory a company should purchase in order to meet its demand while minimizing its holding and storage costs.

That’s because the EOQ formula makes certain assumptions that demand, setup costs, holding costs and goods prices are always constant. 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. If achieved, a company can minimize its costs for buying, delivering, and storing units.

The Assumption that Demand is Constant

They include Zoho Inventory EOQ Calculator, QuickBooks EOQ Calculator, and Omni Calculator.Omni Calculator is the best EOQ formula calculator. The EOQ formula calculator allows you to input your yearly demand, order cost, and yearly cost of holding which it uses to determine your Economic Order Quantity (EOQ). 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. Economic Order Quantity (EOQ) is the order size that minimizes the sum of ordering and holding costs related to raw materials or merchandise inventories.

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. Using EOC helps the company stay ahead of demands and not run out of stocks.

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.

Businesses use it as a valuable tool to make decisions about the number of inventory to order and keep, and how often to reorder to attract the lowest possible costs. The EOQ formula can be paired with the reorder point formula, which helps a business identify when it should order more inventory. Using these calculations together can help a business avoid running out of stock for its products without carrying more inventory than it needs to.

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. EOQ considers the timing of reordering, the cost incurred to place an order, and the costs to store merchandise. If a company is constantly placing small orders to maintain a specific inventory level, the ordering costs are higher, along with the need for additional storage space. They include seasonal changes in inventory costs, changes in demand or orders placed by clients, revenue loss due to shortage of inventory, or discounts realized from purchasing inventory in large quantities. Ordering cost is inversely proportional to holding cost if the annual demand remains constant.

What Are the Basic Assumptions of the EOQ Model?

Economic Order Quantity (EOQ) is a fundamental inventory management technique that helps businesses determine the optimal order quantity that minimizes total inventory costs and is essential in supply chain management. EOQ takes into account both the costs of holding inventory, such as warehousing and storage expenses, and the costs of ordering, such as shipping and handling costs. By finding the ideal balance between these costs, businesses can avoid the pitfalls of overstocking or understocking, thus optimizing their inventory management strategy and ensuring the smooth flow of operations. The goal of calculating the Economic Order Quantity (EOQ) is to identify the optimal number of product units to order.
