Economic Order Quantity: What Does It Mean and Who Is It Important For?

There are some occurrences of inventory damage and shrinkage, which amount to $1,900/year. Let’s say a small furniture manufacturer is renting a workshop for $20,000/year. The warehouse area takes up 25% of the workshop, therefore the yearly rent for the storage area is $5,000.

  1. Nothing puts off customers more than finding out the product they need is out of stock.
  2. Companies utilize it in cash flow planning, minimizing the cost of inventory, and estimating a company’s reordering point.
  3. If there is overstocking, products that are not yet sold are holding warehouse space for a long time.
  4. You sell leashes, muzzles, brushes, treats, collars, chews, bowls, dog food, and more.
  5. “I was working nonstop packing and shipping hundreds of orders every day and hiring friends to help.
  6. Based on the provided information, we have calculated that you should order 1,581 units to keep your inventory costs their lowest.

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. 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. 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 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. 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.

Once again, this is not perfect, but what I advise you and what works best is to take the average cost as a percentage or price per quantity that will give you a good direction. “I can literally go into my ShipBob dashboard and see exactly what I want to see with a few clicks. I can literally not look at the ShipBob platform for 3 weeks, and then log in and within 10 minutes fillable form 941 of analyzing the data, I know exactly where we stand in the business. Using EOQ to balance your inventory can be challenging, but logistics partners like ShipBob can take some of the heavy lifting off your plate. Things like seasonality or big sales can also affect your inventory accuracy. Let’s break down each variable component and go through an example calculation.

Real Function Calculators

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. In cases where the usage of materials or products is unpredictable, the formula becomes useless. The Economic Order Quantity formula only works when the holding costs, ordering costs, and annual demand is predictable. Minimizing the holding costs to the barest minimum is an important aspect of warehouse management. Companies use warehouse inventory management software to help keep their holding costs low. The EOQ helps companies minimize the cost of ordering and holding inventory.

Economic Order Quantity Formula

The EOQ model helps us to calculate what the order size should be to reduce your inventory costs. The model assumes that there are costs related to the ordering and holding of the products in the inventory, and the EOQ calculator helps you keep these costs to the lowest they can be. 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.

Design of optimal quantity discount schedules

The Economic Order Quantity (EOQ) is the point at which the sum of the ordering and holding costs is at the minimum level. Examples of ordering costs include delivery charges, telephone charges, payment processing expenses, invoice verification expenses, and others. 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.

Backordering costs and multiple items

Economic Order Quantity is one of the essential tools companies use in cash flow planning for minimizing the cost of inventory or decreasing the amount of cash held up in inventory. The Economic Order Quantity helps in estimating that level of inventory. The advantage of a large order quantity is reduced ordering costs per unit. However, a disadvantage is the increase in holding costs and risk of stock obsolescence due to the need to store and maintain a larger amount of inventory.

Economic order quantity is best used with other inventory management techniques such as reorder point and safety stock. While the EOQ specifies the lot size of each order, the reorder point is used to determine when an order must be placed for it to be fulfilled on time. Safety stock, however, is the inventory buffer kept just in case for times of unusual demand.

Assumption of Constant Ordering and Holding Costs

It is always good practice to reduce your costs as much as possible, to maximize your profits. Read the next sections to find more about what is EOQ, how to use the simple EOQ formula and what the EOQ meaning is to improve your inventory management. 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. Here is a breakdown of its ordering cost, holding cost, and annual demand for the year.

Many or all of the products featured here are from our partners who compensate us. This influences which products we write about and where and how the product appears on a page. Our partners cannot pay us to guarantee favorable reviews of their products or services. As the company manufactures hardwood furniture, inventory does not depreciate.

The EOQ is usually used to set the reorder point within your inventory management workflows. Together, these metrics tell you when to place an order (reorder point) and how much order to place (EOQ formula). This prevents you from carrying too much deadstock or facing stockouts.

In the end, in this case, we end up with a lower Economic Order Quantity (Q) than in the 1st example, because the demand is lower but also because the cost of the product is higher in terms of stock. As for the order frequency, it will be about 2 months compared to 18 days in example 1. I have another pair of shoes, a little less classic and therefore with lower annual demand, let’s say 1000.
