While economic order quantity can be a helpful metric to leverage in your inventory planning, it may not be the best choice for all brands. Here are a few reasons why EOQ may not be a reliable or valuable solution for your business. According to Bloomberg, around $163 billion worth of inventory is trashed each and every year.
You may think of EOQ not only as a useful model to manage your inventory, but also as a way to manage your company’s cash flow. There are many companies for which inventory costs significantly impact their balance sheet. If we round that up, we see that James’ ideal order size to minimise his costs while meeting customer demand is 32 t-shirts. It’s an important figure for any business trying to minimise overspending while meeting demand, and especially for any business looking to reduce its overall inventory costs. Overall, the benefits of using the EOQ model extend beyond mere cost savings. Calculating the EOQ for your business helps you find a good balance for your order and inventory costs, which are easy to overlook in day-to-day business.
- There is also revenue lost if the company can not fill an order due to insufficient inventory.
- The Economic Order Quantity (EOQ) is an inventory management system that ensures a company orders the right amount of inventory that meets the demand for the product.
- The last limit, Wilson’s formula does not consider safety stocks because he considers that all parameters are constant and stable.
Assuming demand is constant throughout the year – which we’ll talk about more below – James will need to make this order about 31 times a year to meet his demand of selling 1,000 t-shirts. When you’re selling a product and gaining demand, you need to backstock. You want to fulfill the number of orders you’re getting without loads of extra product, and without running out of stock–all the while, trying to keep your costs down and maintaining a level of efficiency. If actual units are not available, then you can use expected sales figure based on your sales trend. EOQ is calculated on a per-product basis – in other words, one product’s EOQ may not be the same as a different product’s EOQ. If your brand has a lot of SKUs in its product catalog, calculating EOQs for all products may be too tedious, time-consuming, or confusing.
Some brands leverage logistics partners like ShipBob that offer software solutions that automatically track sales and order data, which you can quickly review to better forecast demand in the future. The more reliably you can forecast demand, the more frequently you can use the EOQ method, and the easier your inventory replenishment will be. With ShipBob supporting their fulfillment, Bloom has scaled into a 9-figure brand – and shows no signs of slowing down.
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. EOQ considers the timing of reordering, the cost incurred to place an order, and the costs to store merchandise.

This is a unit order, so all the fixed costs generated for each order are considered. The important thing here is to find the intersection point of the 2 curves. This point then gives you the optimal quantity in order to optimize both stock costs and ordering costs.
How to Use EOQ – Example 3
This is what we will try to answer in this article with the economic order quantity (EOQ) or Wilson formula.

When she’s not reading a book with her cat for company, you can usually find her cooking, eating or trying to make her garden productive. EOQ is a formula for calculating minimum purchase order requirements for a business, whereas MOQ is the minimum purchase order for the seller.
Sometimes it makes sense for a retailer to buy a product in bulk from the vendor to get a discount. In such cases, buying items in fewer installments can actually optimize the retailer’s costs despite what the EOQ predicts. Although the formula to calculate EOQ is simple when applied to a single product, calculating it manually for a whole inventory can be time-consuming and there is a margin for human error. Using inventory tools such as QuickBooks Commerce can help you save valuable time.
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. Although Economic Order Quantity is efficient, it can only function in situations where demands are constant.
Order cost (S)
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 any real-world application. Let’s consider a real-life scenario involving a manufacturing company that produces electronic components. The company experiences fluctuating demand for its products due to varying consumer preferences and market trends. The company aims to optimize its inventory management by implementing the economic order quantity model to balance the costs of holding inventory and ordering inventory.

Let’s suppose that the business owner from our previous example has got a volume discount offer. Under this offer, if they order 50 shirts, they will get their shirts for $8 per unit instead of $10. The owner should also be aware that the increased order quantity will also increase the inventory carrying costs.

No formula can account for all the unforeseeable surprises that affect your inventory balance. Unexpected supply chain blockages, theft, spoilage, and more can mess with your inventory levels, and cause your EOQ calculations to be less effective.
To calculate the EOQ for inventory you must know the setup costs, demand rate, and holding costs. 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. By placing a large batch order at once, you would be able to save on your setup cost. But if you order more than you can sell, you will start to rack up holding costs.
The idea is that you don’t end up with not enough stock on hand when a spike in demand hits – leading to stockouts and disappointed customers. You also avoid the opposite situation, where you overstock during a period of low demand, leading to potential spoilage or – at the very least – needlessly high holding costs. The economic order quantity is a method designed to help businesses strategize to minimize their overall costs by learning the trends of their production. https://intuit-payroll.org/ In other words, EOQ helps you plan how much product to keep in stock for the amount of sales you make– keeping you from spending more than you need to. To understand the EOQ Formula, you must first know how to define economic order quantity. Economic order quantity or EOQ is a tool used to determine the volume and frequency of orders that a business must produce in order to reach a specific level of demand, all the while keeping inventory costs low.

By calculating how much you need based on how much you sell in a given period of time, you can also avoid stockouts without keeping too much inventory on hand for too long. Perhaps you’ll discover that ordering in smaller quantities is more cost-effective for your business, or perhaps it’s cheaper to order in bulk. 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.
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. On the other hand, too little inventory can lead to stock-outs which will cause you to lose sales. 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.
