With so many micro-costs and variables involved in the supply chain, it can be difficult to know where to begin optimizing the efficiency of your processes.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Thankfully, the <\/span><b>Economic Order Quantity (EOQ) formula<\/b><span style=\"font-weight: 400;\"> can help you find the ideal amount of inventory to send to and store inside a warehouse at any given time. It\u2019s a pivotal technique that can assist you to make efficient inventory management choices.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Today, we&#8217;re taking a look at why eCommerce businesses should use this formula, how to calculate it and how to optimize inventory levels in general.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>Economic Order Quantity model explained<\/b><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Using the EOQ model can help you make data-lead decisions on how much inventory you have in the warehouse at any given time. The calculation is designed to help you reduce storage, buying, and shipping costs by only storing the ideal amount of stock over a specific period.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">EOQ helps ensure you keep up with demand without paying for storage costs you don&#8217;t need.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>Data you&#8217;ll require for calculating Economic Order Quantity&nbsp;<\/b><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">To calculate your EOQ, there&#8217;s a few bits of data you&#8217;ll need. Much of it is historical data, so the formula works best if you&#8217;ve been trading for at least a year. The longer you&#8217;ve been trading, the more accurate your calculations will be. Here&#8217;s the three bits of data you&#8217;ll need:<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><b>Holding costs<\/b><span style=\"font-weight: 400;\"> \u2013 your holding cost, or carrying cost, are made up of each cost associated with storing inventory. This includes storage costs, labor costs, fulfillment costs, total cost of inventory, insurances, and depreciation costs.<\/span><\/li>\n\n\n\n<li><b>Demand<\/b><span style=\"font-weight: 400;\"> \u2013 the annual demand of your goods. To find this, look at your sales over the past year.<\/span><\/li>\n\n\n\n<li><b>Ordering costs<\/b> <b>or setup cost <\/b><span style=\"font-weight: 400;\">\u2013 The typical fixed cost associated with making an order. This will usually include any shipping, handling, and administration costs you incur when ordering goods.<\/span><\/li>\n\n\n\n<li><b>Variable cost <\/b><span style=\"font-weight: 400;\">\u2013 This includes figures, such as purchase cost and production cost.\u00a0\u00a0<\/span><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">With accurate data in your arsenal, you&#8217;ll be ready to calculate the formula.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>The Economic Order Quantity formula<\/b><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">To calculate your EOQ, take your:<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><b>ordering cost (O)<\/b><b><br><\/b><b>demand (D),<\/b><b><br><\/b><b>holdings costs (H)<\/b><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">and place them into the following formula:<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><b>EOQ = square root of [2O*D] \/ H<\/b><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>EOQ in practice<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Let&#8217;s have a look at the EOQ formula using real numbers. Imagine that you&#8217;ve got an <\/span><b>order cost of \u00a3300, a demand of 6,000 products per yet and an annual holding cost of \u00a30.45 per product<\/b><span style=\"font-weight: 400;\">. The formula would look like this:<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><b>EOQ = square root of (2 x 300 x 6000) \/ 0.45<\/b><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Therefore, <\/span><b>EOQ = 2828 units.<\/b><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>4 Benefits of Economic Order Quantity<\/b><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">There are numerous ways the EOQ calculation can benefit your business. It helps you to find the ideal balance between having enough stock in place while helping minimize costs as low as possible.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">It&#8217;s particularly useful for businesses that shift large amounts of products, or those businesses that sell products with a fluctuating customer demand, such as an online retail clothing shop. Here are some of the benefits of the EOQ formula in more detail:<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>1. Reduce average cost of inventory<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">The more inventory you have inside a warehouse, the higher your costs will be. It&#8217;s far more than just the cost of storage though; with bigger inventory comes more variables, and a higher risk that stock gets damaged during transit, or sits on the shelf for too long.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">An EOQ calculation can help minimize inventory costs by aiding you in preventing overstocking situations, while helping you to eliminate unnecessary risks.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>2. Prevents items from going out of stock<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Every time a product goes out of stock, your business loses money. It can be devastating if this happens to a popular product.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">By using the EOQ formula, you&#8217;re able to have a better grasp of how much inventory you need at all times to prevent <\/span><a href=\"\/stockout-costs\/\"><span style=\"font-weight: 400;\">stockouts<\/span><\/a><span style=\"font-weight: 400;\">, while not paying for unnecessary storage costs.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>3. Helps you make better decisions<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Running an eCommerce business is all about making those tough decisions. Using the EOQ can help you make better decisions based on a tried-and-tested method, rather than guesswork.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">The EOQ calculation makes good use of existing data to help you improve your operational efficiency and make better use of your resources.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>4. Frees up cash<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">As an eCommerce business, much of your assets are held within your products. If you overorder products, you&#8217;ve spent cash unnecessarily and are missing out on the advantages of using it elsewhere.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">By only ordering and storing the optimal amount of goods, you can free up cash to spend on other areas of your business, such as marketing or <\/span><a href=\"https:\/\/www.ecommercefulfilment.com\/en_US\/how-to-improve-your-ecommerce-customer-service\/\"><span style=\"font-weight: 400;\">customer service<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>4 Factors that affect EOQ<\/b><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">It&#8217;s important to remember that the EOQ formula isn&#8217;t perfect, and results will vary depending on a number of factors. The EOQ formula has several assumptions, and its accuracy will diminish if these assumptions aren&#8217;t met.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Here are some factors that affect the EOQ formula:<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>1. Demand<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">The EOQ formula assumes that demand stays constant. If you have various peaks and troughs of demand throughout the year, you may find the calculation to be unreliable.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Therefore, EOQ is more suitable for product lines that have steady, predictable demand throughout the course of the year. It isn&#8217;t particularly useful for seasonal products.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>2. Bulk discounts<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Some suppliers may offer discounts if you purchase in bulk quantities. The EOQ formula won&#8217;t account for this, so it may end up to be more cost-effective if you order more products than the EOQ recommends.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>3. Fixed costs<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">Continuing from the point above, one disadvantage of the EOQ formula is that it assumes that all costs are steady. Once again, it won&#8217;t take into account seasonal variations on inventory costs, <\/span><a href=\"https:\/\/www.ecommercefulfilment.com\/en_US\/order-fulfillment\/shipping\/\"><span style=\"font-weight: 400;\">shipping<\/span><\/a><span style=\"font-weight: 400;\"> costs, geopolitical situations, inventory shortages, and other events outside of your control.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><b>4. Math skills<\/b><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400;\">While the formula itself isn&#8217;t particularly difficult, you will need to have a good understanding of data to use the EOQ formula effectively. Data calculations can be complex, and without a good competency in math it may be difficult to work out sums accurately.
