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. Economic order quantity (EOQ) is the ideal quantity of units a company should purchase to meet demand while minimizing inventory costs such as holding costs, shortage costs, and order costs.
- When a business orders more inventory than it has demand for, it leads to high ordering costs as the company spends more of its cash flow on inventory.
- When you use a robust ERP, these calculations may all be handled for you, including order costs like inventory ordering costs, holding costs and stockout costs.
- Once you receive your cement bags, it costs $3 per bag per year to store your concrete.
- EOQ is part of inventory management that ensures the inventory is always monitored.

The EOQ assumes the lowest level at which stock can be reduced to is zero. Identifying the optimal number of products to order is the main purpose of the Economic Order Quantity (EOQ). The ordering costs answer the question “How much does an order cost per purchase? Economic Order Quantity shows business owners if current order quantities are reasonable or not.
Backordering costs and multiple items
Holding inventory can be one of the most expensive aspects of ecommerce fulfillment. It’s expensive to manufacture or procure and it is expensive to keep in stock. Whether it is raw materials, work in process (WIP) or finished goods, companies can use EOQ as an efficient ordering guideline to prevent shortages while not maintaining excess inventories. Economic order quantity is often one of many inventory forecasting techniques available in an inventory control or ERP solution. 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.
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. To understand the economic order formula, you’ve first got to understand how inventory costs are calculated.
What Are the Basic Assumptions of the EOQ Model?
But it also involves doing a fair bit of math—making it a relatively difficult model to implement if you’re tracking your inventory manually. This puts business owners with no mathematical skills at a disadvantage. The efficient Economic Order Quantity (EOQ) models require detailed data to calculate several figures. To minimize holding and order costs, the furniture company should order 26 units. The Economic Order Quantity determines the inventory reorder point of a company. By doing so, the company continues to fill orders and does not run out of inventory.
- In many cases, you can incorporate the EOQ of a product into a point-of-sale system.
- If your business doesn’t see a lot of fluctuation, the EOQ formula can be easily implemented in a manual inventory tracking system.

- From the formula above, we see that ordering the higher quantity would bring our inventory costs down to $61,515—a $1,485 savings.
Fortunately, this problem is easily solved if you calculate a safe reorder point that takes your supply chain and manufacturer’s lead time into consideration. While the EOQ model is a good guideline for balancing the costs of your inventory on hand and the costs of producing your inventory, it isn’t foolproof.

Faults and malfunctions tend to occur in machines, warehouses, materials, etc which may alter the normal functioning of the inventory and slow down the flow of demands. There are times when the cost of estimation and calculation exceeds the savings made by buying that quantity.
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. 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. EOQ takes into account the timing of reordering, the cost incurred to place an order, and the cost to store merchandise.

Example of EOQ formula calculation
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. The EOQ is designed to help companies or small businesses strategize to minimize their overall costs by learning the trends of their production. 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. Also, as the number of orders decreases, the ordering cost decreases but the holding cost increases.
Disadvantages of Using Economic Order Quantity
That’s where the economic order quantity (EOQ) model comes into play. Although Economic Order Quantity is efficient, it can only function in situations where demands are constant. In situations where the demand is not consistent, the Economic Order Quantity (EOQ) will provide a misleading figure. The amount of money spent on inventory storage becomes lesser and more affordable. For example, a business owner becomes aware of the risk of over-stocking if he or she decides to order a certain amount of new stocks at a particular time.
