The XYZ Equipment Company estimates its carrying cost at 15% and its ordering cost at $9 per order. The estimated annual requirement is 48,000 units at a price of $4 per unit. Average carrying cost is taken as 15% to 25% of the value of average working cost, which usually amounts to 50% of the order quantity. To find out the annual demand, you multiply the number of products it sells per month by 12.

Using EOC helps the company stay ahead of demands and not run out of stocks. Stocks are available in abundance and deadlines are easily met when you use the Economic Order Quantity to perfection. This results in keeping long-term customers and clients, and lower customer acquisition costs (CAC). The EOQ assumes demand is constant and inventory is reduced at a fixed rate until it reaches zero. EOQ ensures that a company witnesses no shortage of inventory with no additional cost.

- The EOQ formula shouldn’t be taken as gospel, but it’s a useful tool for informed, effective inventory control.
- Calculating the setup or ordering cost is very easy as it is usually a fixed cost and is not very prone to fluctuation.
- There are many companies for which inventory costs significantly impact their balance sheet.
- The value of economic order quantity tell you the number of units you should order to minimize your holding and ordering costs.

Because you can derive accurate reorder points from the economic order quantity formula, it can save you from tremendous stress. A reordering point can go a long way when trying to understand when you need to restock your inventory to meet demand. Companies often overstock in fear of a sudden spike in consumer demand. Seeing how much money is spent on unused inventory, companies are starting to pay heed to their economic order quantity.

## Constant Delivery Time

As inventory costs are optimized, you may consider changes in the product’s price policy. Other techniques to consider include period order quantity, least total cost, least unit costs, and lot for lot. You also have to assume order costs remain fairly constant, meaning that the formula doesn’t account for possible vendor discounts that you’d get for placing certain-sized orders. 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. The application of tabular approach is not common as it is more time consuming as compared to formula approach. Moreover, in some situations, it provides only an estimate of economic order quantity and is therefore not as accurate as the formula approach.

## Drawback of the EOQ formula: The annual timeline

It assumes that there is a trade-off between inventory holding costs and inventory setup costs, and total inventory costs are minimized when both setup costs and holding costs are minimized. Holding cost is the total costs a company incurs to hold inventory in a warehouse or store. The total holding costs depend on the size of the order placed for inventory.

When you have just the right amount of stock, you can not only save money on ordering costs but also on storage costs that arise from overstocking. Having the optimal order quantity also has a few unforeseen advantages on management for many companies. 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 are so many online Economic Order Quantity (EOQ) calculators you can use to calculate EOQ for your company.

Consider calculating an overall average to estimate how much stock you need to meet the customer demand. For example, consider a retail clothing shop that carries a line of men’s shirts. It costs the company $5 per year to hold a single shirt in inventory, and the fixed cost to place an order is $2.

When you apply EOQ principles, you assume that each unit has a cost for warehousing and holding it until you order again. In practice, you will sell some of the inventory much sooner than the reorder date, so you do not actually incur the projected holding cost. You could be showing less profit for your company because you assume the maximum holding expense for each unit of inventory. One way to rectify this is to discount your holding cost to allow for the fact that not all units are being held for the same amount of time.

Also, it leads to high holding costs as the inventory tends to spend a long time in the warehouse since the supply exceeds demand for the product. The EOQ formula is the square root of (2 x 1,000 shirts 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 shirts. You probably noticed that some of the variables require information on an annual timeline.

Purchasing or buying in large quantities implies low acquisition or purchasing costs (i.e., the number of purchase orders placed with the suppliers is small) and high carrying costs. It is worth noting that material acquisition costs and material carrying costs behave quite differently. The Economic Order Quantity (EOQ) is the specific total order amount for a firm’s inventory that minimizes the total cost of inventory management.

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.
