From the formula above, we see that ordering the higher quantity would bring our inventory costs down to $61,515—a $1,485 savings. Now, the example we used above is pretty simplistic—and unfortunately, calculating real-life inventory costs is rarely that easy. By optimizing order quantities for various components, the manufacturer can reduce storage costs, minimize production interruptions, and maintain efficiency. Lead time demand means the amount of demand you anticipate the product will have between now and when the delivery will arrive to replenish your stock.
What are the Importants of Economic Order Quantity?
Understanding your business’s EOQs is crucial for creating a positive customer experience and saving your company money on 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. The supplier also has the minimum quantity per order, which depends on other factors such as the nature of material, size and safety. Placing order outside of supplier standard may result in additional cost, and it may not possible. For example, consumer goods producers require well-balanced inventories at the point of sale.
EOQ is an important cash flow tool for management to minimize the cost of inventory and the amount of cash tied up in the inventory balance. For many companies, inventory is the largest asset owned by the company, 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. Economic order quantity (EOQ) is the ideal order quantity a company should purchase for its inventory given a set cost of production, a certain demand rate, and other variables. When it comes to inventory management, knowing what you’ve got, where it is, and how much of it you have on hand is absolutely essential. This knowledge is key to practicing proper inventory control, the balancing act of stocking just enough inventory to meet customer demand without sacrificing profitability.
Clients of industrial and commercial producers usually do not require the same degree of delivery lead time. Smaller businesses also face financial and logistical limitations when starting their inventory systems, so it’s key that you choose the most effective method that suits your organisation. Unfortunately, ordering such a low quantity of bags at a time means you have to place more orders throughout the year, which means you pay the $100 purchasing fee more often.
Cut Costs and Streamline Your Supply Chain Process
There is also a cost for each unit held in storage, commonly known as holding cost, sometimes expressed as a percentage of the purchase cost of the item. Although the EOQ formulation is straightforward, factors such as transportation rates and quantity discounts factor into its real-world application. To minimize its inventory carrying costs, a company must place small orders. But small order size means that the company must place more orders which increases its total ordering costs.
Leveraging EOQ for Optimized Inventory Control
When you do the math, you find that ordering fewer units basics of business accounting at a time brings your total cost down to $63,000. Malakooti (2013)10 has introduced the multi-criteria EOQ models where the criteria could be minimizing the total cost, Order quantity (inventory), and Shortages. Additionally, the economic order interval8 can be determined from the EOQ and the economic production quantity model (which determines the optimal production quantity) can be determined in a similar fashion. Perera et al. (2017)4 establish this optimality and fully characterize the (s,S) optimality within the EOQ setting under general cost structures. FreshBooks expense-tracking software solutions help businesses organize their receipts and spending and automatically track and categorize inventory expenses. This gives company owners the data they need to analyze their spending and profits, with no manual entry required.
Improve cash flow
The EOQ helps you strike the perfect balance, ensuring you have enough stock without becoming a hoarder. Notice that the quantity of 400 units with 6 annual orders and a combined ordering and holding cost of $120 is the most economical quantity to order. Other order quantities that result in more or less than six orders per year are not so economical. The ordering costs are the costs that are incurred every time an order for inventory is placed with the supplier.
Safety stock is the amount of extra inventory you keep on hand to ensure you don’t run out. Determining the correct amount of inventory requires you to estimate needs based on historical demand. This can be time-consuming if you’re using spreadsheets and have no tracking in place. Inventory management software, however, can pull this information together in a few clicks, so you can apply the right data to your EOQ formula. Also known as “optimum lot size,” economic order quantity refers to the number of units you should add to inventory with each purchase order. It is a well-known fact that the cost of ordering the inventory decreases with the increase in volume, because of economies of scale, but due to the increase in the size of the inventory, the carrying cost increases.

While the EOQ formula is a valuable tool, it’s important to remember that it’s a simplification.

These include communication costs, transportation costs, transit insurance costs, inspection costs, accounting costs, etc. These include opportunity cost of money held-up in inventories, storage costs such as warehouse rent, insurance, spoilage costs, etc.
