You will understand what reorder points are, how to calculate them, and their critical role in warehouse operations, inventory management, and overall business efficiency.<\/p>\n<p><strong>Key Takeaways:<\/strong><\/p>\n<ul>\n<li>Reorder points are crucial for maintaining healthy inventory levels and preventing stock-outs or overstocking, calculated using historical sales data and supplier lead times.<\/li>\n<li>Every SKU should have a unique reorder point to account for differences in product movement rates.<\/li>\n<li>Warehouse management systems can automate the process of reorder point tracking and order placement, increasing operational efficiency.<\/li>\n<li>Safety stock and reorder points work in tandem to prevent stockouts, with the calculation of safety stock taking into account service levels and lead time standard deviation.<\/li>\n<li>It&#8217;s essential to regularly update your reorder points as underlying metrics such as lead time and daily usage can fluctuate over time.<\/li>\n<\/ul>\n<h2>Inventory Reorder Points (ROP): What They Are &amp; How They Help<\/h2>\n<p>How do you know when to order more inventory?<\/p>\n<p>In the early days of your business, you probably used your instincts. Once every two weeks, you\u2019d eyeball your stock, guess what you\u2019d run out of in the next few days, and put in an order.<\/p>\n<p><!--more--><\/p>\n<p>As your business gets busier and your responsibilities grow, running on instinct is not scalable. Your operations and <a href=\"\/blog\/product-master-data-management\" rel=\" noopener\">product master data<\/a> become more complex, and things start to slide.<\/p>\n<p>For instance, you may come in one Monday morning only to realize you\u2019re out of a key product. Customer orders are pouring in and you remember your supplier has a lead time of one week. In the meantime, all you can do is hope your customers will be patient or eat the cost of lost business.<\/p>\n<p>In another scenario, you may notice that every week you\u2019re overflowing with one set of products that become damaged or spoiled while consistently running out of another that you need to do <a href=\"\/blog\/stock-and-inventory-replenishment\" rel=\" noopener\">stock replenishment<\/a>.<\/p>\n<p>So, how do growing businesses prevent this from happening?<\/p>\n<p>By setting reorder points(also known as reorder level) based on historical data.<\/p>\n<p>The definition of reorder point is the point at which you send a purchase order to your supplier or manufacturer.<\/p>\n<p>Your gut doesn\u2019t determine your reorder level or reorder level. Your historical data and lead times do. This approach ensures your business maintains healthy inventory levels at all times.<\/p>\n<p>Another important feature of reorder points is that they are unique to every <a href=\"\/blog\/manage-inventory-with-sku\" target=\"_blank\" rel=\"noopener\">SKU<\/a>. A common mistake business owners make is reordering <i>everything <\/i>at the same time, even though different products move at different rates. This strategy means that some products are ordered too often while other products aren\u2019t ordered enough.<\/p>\n<div class=\"blog-toc\">\n<p>In this post, we\u2019ll cover:<\/p>\n<ol>\n<li><a href=\"#1\" rel=\"noopener\">How to calculate reorder points formula<\/a><\/li>\n<li><a href=\"#2\" rel=\"noopener\">Where reorder points fit in your warehouse operations<\/a><\/li>\n<li><a href=\"#3\" rel=\"noopener\">How reorder points relate to safety stock<\/a><\/li>\n<li><a href=\"#4\" rel=\"noopener\">Reorder point formula variable fluctuation<\/a><\/li>\n<li><a href=\"#5\" rel=\"noopener\">Why reorder point calculation is considered a best practice<\/a><\/li>\n<\/ol>\n<\/div>\n<h2 id=\"1\">How Do You Calculate the Reorder Point Formula of a Product?<\/h2>\n<p>Now that we know what a reorder point is and why it\u2019s important, how do you actually determine what level of inventory should trigger a new order?<\/p>\n<p>You can start by using the reorder point calculation formula:<\/p>\n<p><strong>Reorder point formula = Average daily usage * lead time<\/strong><\/p>\n<p>Let\u2019s assume that your business sells computer keyboards.<\/p>\n<p>Your average daily usage is the average amount of keyboards you sell every day. You can find this number by adding up your daily orders and dividing it by the number of days in the period. For instance, if you add up thirty days of orders and get 300, you would divide it by 30.<\/p>\n<p><strong>So your average daily usage would be 10.\u00a0<\/strong><\/p>\n<p>Your lead time is the amount of time it takes a supplier to send the keyboards from the moment they receive a <a href=\"\/blog\/purchase-order\">purchase order.<\/a> Let\u2019s assume for the purpose of this example that it takes your supplier 5 days, at the most, to deliver new keyboards.<\/p>\n<p><strong>So your lead time would be 5.\u00a0<\/strong><\/p>\n<p>One you have this information, you simply multiply the two numbers together.<\/p>\n<p><strong>Your reorder point would be 50.\u00a0<\/strong><\/p>\n<p>In other words, each time your stock hits 50 keyboards, you would send a purchase order to your keyboards supplier.<\/p>\n<p>Businesses using reorder point calculator spreadsheets can find their reorder points in Excel by using the formula above in the spreadsheet holding their inventory data.<\/p>\n<p>That said, this is not good business practice. For a growing warehouse or distribution center, managing inventory data in spreadsheets introduces challenges around version control, data analysis, and <a href=\"\/blog\/real-time-inventory-management-data\" target=\"_blank\" rel=\"noopener\">real-time inventory data<\/a> retrieval.<\/p>\n<p>A more reliable approach uses technology, like <a href=\"https:\/\/www.logiwa.com\/solutions\/digital-warehouse-management-software\" rel=\"noopener\">warehouse management software<\/a> or <a href=\"https:\/\/www.logiwa.com\/industries\/ecommerce-inventory-management-software\" rel=\" noopener\">inventory management software<\/a>, to help identify and track inventory reorder points and place new orders with suppliers.Remember, there is a difference between a product\u2019s reorder point and reorder quantity. Your inventory reorder point indicates <i>when <\/i>to order more stock. Your reorder quantity is <i>how much <\/i>additional stock you wish to order.<\/p>\n<h2 id=\"2\">How Reorder Points Fit Into a Warehouse\u2019s Major Business Systems<\/h2>\n<p>Warehouses and distribution centers focused on growth, efficiency, and scalability use warehouse management systems (WMS) and inventory management systems instead of Excel spreadsheets. These systems automate manual processes that are prone to human error or oversight. Ordering inventory is one example of an important process that can be automated with the right software.<\/p>\n<p>For instance, reorder points are only useful when businesses act upon them. If your business knows the reorder point of keyboards is 50, but there\u2019s no mechanism to alert workers when there are only 50 left, you\u2019re back to square one: frantically calling your supplier when you realize you\u2019re out of stock.<\/p>\n<p>This is one of the main problems with calculating in reorder point calculator Excel spreadsheets. Someone has to export up-to-date data before the reorder point can be calculated. This is a step that will likely be overlooked when the warehouse is busy and, of course, busy periods are when businesses need inventory oversight the most.<\/p>\n<p>On the other hand, a WMS can send a notification to a supervisor or manager to let them know that a specific product has hit its reorder level. Furthermore, warehouse managers can program their software to automatically send a purchase order to suppliers when a product hits the reorder level, bypassing the notification and approval process.<\/p>\n<p>&nbsp;[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.22.2&#8243; _module_preset=&#8221;default&#8221; width=&#8221;auto&#8221; custom_margin=&#8221;15px|auto|15px|auto|false|false&#8221; custom_css_main_element=&#8221;.hbspt-form .legal-consent-container a {||    color: white !important;||}&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221; global_module=&#8221;26788&#8243; theme_builder_area=&#8221;post_content&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.22.2&#8243; _module_preset=&#8221;default&#8221; use_background_color_gradient=&#8221;on&#8221; background_color_gradient_stops=&#8221;#481a96 0%|#200741 100%&#8221; custom_padding=&#8221;15px|35px|15px|35px|true|true&#8221; border_radii=&#8221;on|10px|10px|10px|10px&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_text _builder_version=&#8221;4.22.2&#8243; _module_preset=&#8221;default&#8221; header_3_text_color=&#8221;#ffffff&#8221; header_3_font_size=&#8221;30px&#8221; header_3_font_size_tablet=&#8221;30px&#8221; header_3_font_size_phone=&#8221;20px&#8221; header_3_font_size_last_edited=&#8221;on|phone&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<\/p>\n<h3 style=\"text-align: center;\">Request a free demo to learn more about Logiwa WMS.<\/h3>\n<p>[\/et_pb_text][et_pb_code _builder_version=&#8221;4.22.2&#8243; _module_preset=&#8221;default&#8221; text_orientation=&#8221;center&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<script charset=\"utf-8\" type=\"text\/javascript\" src=\"\/\/js.hsforms.net\/forms\/embed\/v2.js\"><\/script><!-- [et_pb_line_break_holder] --><script><!-- [et_pb_line_break_holder] -->  hbspt.forms.create({<!-- [et_pb_line_break_holder] -->    portalId: \"3469233\",<!-- [et_pb_line_break_holder] -->    formId: \"350e3ad2-eb09-46b1-9079-3f728ec2c0ea\",<!-- [et_pb_line_break_holder] -->    region: \"na1\"<!-- [et_pb_line_break_holder] -->  });<!-- [et_pb_line_break_holder] --><\/script>[\/et_pb_code][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=&#8221;row&#8221; _builder_version=&#8221;4.16&#8243; background_size=&#8221;initial&#8221; background_position=&#8221;top_left&#8221; background_repeat=&#8221;repeat&#8221; width=&#8221;auto&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221; locked=&#8221;off&#8221;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.16&#8243; custom_padding=&#8221;|||&#8221; global_colors_info=&#8221;{}&#8221; custom_padding__hover=&#8221;|||&#8221; theme_builder_area=&#8221;post_content&#8221;][et_pb_text ul_item_indent=&#8221;30px&#8221; _builder_version=&#8221;4.22.2&#8243; _module_preset=&#8221;default&#8221; header_4_font_size=&#8221;16px&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221;]<\/p>\n<h2 id=\"3\">What Is the Relationship Between Reorder Points and Safety Stock?<\/h2>\n<p>Stockouts are expensive. Worldwide, stockouts cost retailers an estimated $984 billion in lost sales. In North America alone, businesses lose roughly $144.9 billion dollars.<\/p>\n<p>The lesson is simple: Customers won\u2019t wait for you to restock your shelves, so you better have what they\u2019re looking for, when they\u2019re looking for it.<\/p>\n<p>Consequently, businesses have embraced something called <a href=\"https:\/\/www.logiwa.com\/blog\/safety-stock\">safety stock, also known as buffer stock<\/a>. It\u2019s an in-case-of-emergency stock businesses keep in case there\u2019s an unexpected increase in demand or shortage in supply.<\/p>\n<p>When it comes to preventing stockouts, safety stock is the last line of defense. Your reorder level is your second-to-last line of defense. In other words, they both work toward the same goal. Reorder point formulas are all about prevention while stockouts are a cure.<\/p>\n<p>Some businesses don\u2019t include their buffer stock in their calculation of reorder point formula while other businesses do. Those that do simply adjust the formula to add their safety stock:<\/p>\n<p>Reorder point formula = (Average daily usage * lead time) + safety stock<\/p>\n<p>Like reorder points, buffer stock levels should be set using historical data, not gut feeling. Choosing to order the same excess amount of <i>all <\/i>products is an expensive strategy for one big reason: carrying costs.<\/p>\n<p>Your carrying cost is the money you pay to keep inventory and it can be an enormous expense. Carrying cost include expenses like:<\/p>\n<ul>\n<li>Rent\/storage space for products<\/li>\n<li>Labor costs for employees who manage or guard inventory<\/li>\n<li>Insurance<\/li>\n<\/ul>\n<p>In addition, products that sit around for a long period of time have a higher chance of spoilage, damage, loss, or theft. You\u2019ll face added risk in potential for reduced demand. After some time, moving some products becomes impossible, forcing businesses to write them off as a loss.<\/p>\n<p>So, how can companies effectively calculate their safety stock?<\/p>\n<p>Safety Stock = Desired Service Level * Standard Deviation of Lead Time * Demand Average<\/p>\n<p><!-- In-Page Optin Box --><\/p>\n<p class=\"in-content-optin\"><strong>BONUS:<\/strong>\u00a0Before you read further,\u00a0our team has put together a simple\u00a0safety stock calculation excel\u00a0that helps you identify how much inventory to carry for each of your products.\u00a0<a href=\"https:\/\/www.logiwa.com\/resources\/templates\/safety-stock-calculator-excel-template\" target=\"_blank\" rel=\"noopener\">Download safety stock calculator excel here.<\/a><\/p>\n<h3>Desired Service Level<\/h3>\n<p>Companies assign different service levels to different products. The service level represents the cost of missing out on a sale versus the cost of purchasing more inventory.<\/p>\n<p>For most companies, service levels float somewhere between 90 and 100 percent. For instance, if your service level is 92 percent, you\u2019re saying you want to fulfill orders for this product at least 92 percent of the time.<\/p>\n<p>Once you have decided on your desired service level, you need to express it as a factor. You can convert your factor by using a formula in Excel (=NORMSINV (X%)) or by referring to a factor table.<\/p>\n<p><strong>Our 92% service level expressed as a factor is 1.41.<\/strong><\/p>\n<h3>Standard Deviation of Lead Time<\/h3>\n<p>To find your standard deviation of lead time, you need access to historical data. The more data the better since you want your standard deviation of lead time to be an accurate reflection of reality.<\/p>\n<p>While businesses have an official lead time from suppliers in their service level agreements, the exact number can vary from time to time. Some suppliers exceed expectations. If their SLA says 5 days, they more often than not deliver within 2 days. Other suppliers occasionally deliver late.<\/p>\n<p>The standard deviation helps you express how reliable your suppliers actually are, so you can better calculate your buffer stock. This is why having ample historical data is helpful.<\/p>\n<p>Let\u2019s return to our keyboard example. Earlier, we used an average lead time on the assumption that there was no set service level agreement with our supplier. We calculated that, on average, our supplier fulfills our keyboard orders in 5 days.<\/p>\n<p>In this case, we\u2019re going to assume that our SLA is 15 days instead of 5. We would use this number, in addition to our historical data, to find our standard deviation.<\/p>\n<table style=\"border-color: #99acc2; border-collapse: collapse; table-layout: fixed; border-style: solid;\" border=\"1\" cellpadding=\"4px\">\n<tbody>\n<tr>\n<td style=\"padding: 4px;\"><strong>Actual Lead Time (in days)<\/strong><\/td>\n<td style=\"padding: 4px;\"><strong>Expected Lead Time (in days)<\/strong><\/td>\n<td style=\"padding: 4px;\"><strong>Deviance<\/strong><\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">0<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">13<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">+2<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">12<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">+3<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">14<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">+1<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">16<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">-1<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">16<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">-1<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">18<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">-3<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">11<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">+4<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">15<\/td>\n<td style=\"padding: 4px;\">0<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><i>Table: Finding the standard deviation of lead time (<\/i><i>Logiwa<\/i><i>)<\/i><\/p>\n<p>First, find the difference between the expected lead time and the actual lead time and place this in the deviance column.

There are several inventory management practices that are unavoidably labor intensive, like conducting annual counts or cycle counts, so it\u2019s important to automate whenever possible. Calculating inventory reorder points, tracking inventory levels and placing orders can be effectively automated using warehouse and inventory management software.<\/p>\n<p>Using inventory reorder points as part of your inventory management strategy also helps you keep your distribution costs low. Some businesses who run their operations from <a href=\"https:\/\/www.logiwa.com\/blog\/multi-warehouse-management\">multiple warehouses<\/a> use the location of their warehouses as a strategy for cost savings.<\/p>\n<p>For instance, their order management system&#8217;s <a href=\"\/blog\/smart-order-routing\" rel=\" noopener\">order routing<\/a> module identifies the delivery address for a customer and then pushes the order to the warehouse closest to that customer.<\/p>\n<p>This way, the business saves on transportation costs. If reorder points don\u2019t automatically trigger a purchase order, warehouses can no longer take advantage of this cost-saving strategy since the warehouse closest to a customer may be out of stock.<\/p>\n<h2>Enhance Inventory Management with the Reorder Point Formula<\/h2>\n<p>Mastering the reorder point formula is key to efficient inventory management. It aids in maintaining optimal stock levels, preventing stockouts, and making your operations more scalable and cost-effective. However, remember that the underlying metrics for your reorder points may change over time. As such, periodically updating your reorder points based on the most recent data is a must-do.<\/p>\n<p>For an even more streamlined experience, consider automating this process. <a href=\"https:\/\/www.logiwa.com\/request-a-demo\">Get started today<\/a> with Logiwa WMS, our state-of-the-art warehouse management system, designed to facilitate data-based decision-making and efficiency in your inventory management.

Once every two weeks, you\u2019d eyeball your stock, guess what you\u2019d run out of in the next few days, and put in an order.\r\n\r\n<!--more-->\r\n\r\nAs your business gets busier and your responsibilities grow, running on instinct is not scalable. Your operations and <a href=\"\/blog\/product-master-data-management\" rel=\" noopener\">product master data<\/a> become more complex, and things start to slide.\r\n\r\nFor instance, you may come in one Monday morning only to realize you\u2019re out of a key product. Customer orders are pouring in and you remember your supplier has a lead time of one week. In the meantime, all you can do is hope your customers will be patient or eat the cost of lost business.\r\n\r\nIn another scenario, you may notice that every week you\u2019re overflowing with one set of products that become damaged or spoiled while consistently running out of another that you need to do <a href=\"\/blog\/stock-and-inventory-replenishment\" rel=\" noopener\">stock replenishment<\/a>.\r\n\r\nSo, how do growing businesses prevent this from happening?\r\n\r\nBy setting reorder points(also known as reorder level) based on historical data.\r\n\r\nThe definition of reorder point is the point at which you send a purchase order to your supplier or manufacturer.\r\n\r\nYour gut doesn\u2019t determine your reorder level or reorder level. Your historical data and lead times do. This approach ensures your business maintains healthy inventory levels at all times.\r\n\r\nAnother important feature of reorder points is that they are unique to every <a href=\"\/blog\/manage-inventory-with-sku\" target=\"_blank\" rel=\"noopener\">SKU<\/a>. A common mistake business owners make is reordering <i>everything <\/i>at the same time, even though different products move at different rates. This strategy means that some products are ordered too often while other products aren\u2019t ordered enough.\r\n<div class=\"blog-toc\">\r\n\r\nIn this post, we\u2019ll cover:\r\n<ol>\r\n \t<li><a href=\"#1\" rel=\" noopener\">How to calculate reorder points formula<\/a><\/li>\r\n \t<li><a href=\"#2\" rel=\" noopener\">Where reorder points fit in your warehouse operations<\/a><\/li>\r\n \t<li><a href=\"#3\" rel=\" noopener\">How reorder points relate to safety stock<\/a><\/li>\r\n \t<li><a href=\"#4\" rel=\" noopener\">Reorder point formula variable fluctuation<\/a>s<\/li>\r\n \t<li><a href=\"#5\" rel=\" noopener\">Why reorder point calculation is considered a best practice<\/a><\/li>\r\n<\/ol>\r\n<\/div>\r\n<h2 id=\"1\">How Do You Calculate the Reorder Point Formula of a Product?<\/h2>\r\nNow that we know what a reorder point is and why it\u2019s important, how do you actually determine what level of inventory should trigger a new order?\r\n\r\nYou can start by using the reorder point calculation formula:\r\n\r\n<strong>Reorder point formula = Average daily usage * lead time<\/strong>\r\n\r\nLet\u2019s assume that your business sells computer keyboards.\r\n\r\nYour average daily usage is the average amount of keyboards you sell every day. You can find this number by adding up your daily orders and dividing it by the number of days in the period. For instance, if you add up thirty days of orders and get 300, you would divide it by 30.\r\n\r\n<strong>So your average daily usage would be 10.\u00a0<\/strong>\r\n\r\nYour lead time is the amount of time it takes a supplier to send the keyboards from the moment they receive a purchase order. Let\u2019s assume for the purpose of this example that it takes your supplier 5 days, at the most, to deliver new keyboards.\r\n\r\n<strong>So your lead time would be 5.\u00a0<\/strong>\r\n\r\nOne you have this information, you simply multiply the two numbers together.\r\n\r\n<strong>Your reorder point would be 50.\u00a0<\/strong>\r\n\r\nIn other words, each time your stock hits 50 keyboards, you would send a purchase order to your keyboards supplier.\r\n\r\nBusinesses using reorder point calculator spreadsheets can find their reorder points in Excel by using the formula above in the spreadsheet holding their inventory data.\r\n\r\nThat said, this is not good business practice. For a growing warehouse or distribution center, managing inventory data in spreadsheets introduces challenges around version control, data analysis, and <a href=\"\/blog\/real-time-inventory-management-data\" target=\"_blank\" rel=\"noopener\">real-time inventory data<\/a> retrieval.\r\n\r\nA more reliable approach uses technology, like <a href=\"\/\" rel=\"noopener\">warehouse management software<\/a> or <a href=\"\/inventory-management-software\" rel=\" noopener\">inventory management software<\/a>, to help identify and track inventory reorder points and place new orders with suppliers.\r\n<p id=\"order-picking-goals\">Remember, there is a difference between a product\u2019s reorder point and reorder quantity. Your inventory reorder point indicates <i>when <\/i>to order more stock. Your reorder quantity is <i>how much <\/i>additional stock you wish to order.<\/p>\r\n\r\n<div id=\"integrations\" class=\"dark-blue-bg\">\r\n<div class=\"container\">\r\n<div class=\"row\">\r\n<div class=\"col-md-9 mx-auto\" align=\"center\">\r\n<div class=\"integrations-intro\">\r\n<div class=\"animatedParent\" data-sequence=\"500\"><\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"row\">\r\n<div class=\"col-lg-4 col-md-6\">\r\n<div class=\"animatedParent\">\r\n<div class=\"integration-box animated growIn go\">\r\n\r\n<span style=\"color: #333333; font-size: 26px;\">How Reorder Points Fit Into a Warehouse\u2019s Major Business Systems<\/span>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\nWarehouses and distribution centers focused on growth, efficiency, and scalability use warehouse management systems (WMS) and <a href=\"https:\/\/www.logiwa.com\/inventory-management-software\">inventory management systems<\/a> instead of Excel spreadsheets. These systems automate manual processes that are prone to human error or oversight. Ordering inventory is one example of an important process that can be automated with the right software.\r\n\r\nFor instance, reorder points are only useful when businesses act upon them. If your business knows the reorder point of keyboards is 50, but there\u2019s no mechanism to alert workers when there are only 50 left, you\u2019re back to square one: frantically calling your supplier when you realize you\u2019re out of stock.\r\n\r\nThis is one of the main problems with calculating in reorder point calculator Excel spreadsheets. Someone has to export up-to-date data before the reorder point can be calculated. This is a step that will likely be overlooked when the warehouse is busy and, of course, busy periods are when businesses need inventory oversight the most.\r\n\r\nOn the other hand, a WMS can send a notification to a supervisor or manager to let them know that a specific product has hit its reorder level. Furthermore, warehouse managers can program their software to automatically send a purchase order to suppliers when a product hits the reorder level, bypassing the notification and approval process.\r\n<h2 id=\"3\">What Is the Relationship Between Reorder Points and Safety Stock?<\/h2>\r\nStockouts are expensive. Worldwide, stockouts cost retailers an estimated $984 billion in lost sales. In North America alone, businesses lose roughly $144.9 billion dollars.\r\n\r\nThe lesson is simple: Customers won\u2019t wait for you to restock your shelves, so you better have what they\u2019re looking for, when they\u2019re looking for it.\r\n\r\nConsequently, businesses have embraced something called <a href=\"https:\/\/www.logiwa.com\/blog\/safety-stock\">safety stock, also known as buffer stock<\/a>. It\u2019s an in-case-of-emergency stock businesses keep in case there\u2019s an unexpected increase in demand or shortage in supply.\r\n\r\nWhen it comes to preventing stockouts, safety stock is the last line of defense. Your reorder level is your second-to-last line of defense. In other words, they both work toward the same goal. Reorder point formulas are all about prevention while stockouts are a cure.\r\n\r\nSome businesses don\u2019t include their buffer stock in their calculation of reorder point formula while other businesses do. Those that do simply adjust the formula to add their safety stock:\r\n\r\nReorder point formula = (Average daily usage * lead time) + safety stock\r\n\r\nLike reorder points, buffer stock levels should be set using historical data, not gut feeling. Choosing to order the same excess amount of <i>all <\/i>products is an expensive strategy for one big reason: carrying costs.\r\n\r\nYour carrying cost is the money you pay to keep inventory and it can be an enormous expense. Carrying cost include expenses like:\r\n<ul>\r\n \t<li>Rent\/storage space for products<\/li>\r\n \t<li>Labor costs for employees who manage or guard inventory<\/li>\r\n \t<li>Insurance<\/li>\r\n<\/ul>\r\nIn addition, products that sit around for a long period of time have a higher chance of spoilage, damage, loss, or theft. You\u2019ll face added risk in potential for reduced demand. After some time, moving some products becomes impossible, forcing businesses to write them off as a loss.\r\n\r\nSo, how can companies effectively calculate their safety stock?\r\n\r\nSafety Stock = Desired Service Level * Standard Deviation of Lead Time * Demand Average\r\n\r\n<!-- In-Page Optin Box -->\r\n<p class=\"in-content-optin\"><strong>BONUS:<\/strong>\u00a0Before you read further,\u00a0our team has put together a simple\u00a0safety stock calculation excel\u00a0that helps you identify how much inventory to carry for each of your products.\u00a0<a href=\"https:\/\/www.logiwa.com\/resources\/templates\/safety-stock-calculator-excel-template\" target=\"_blank\" rel=\"noopener\">Download safety stock calculator excel here.<\/a><\/p>\r\n\r\n<h3>Desired Service Level<\/h3>\r\nCompanies assign different service levels to different products. The service level represents the cost of missing out on a sale versus the cost of purchasing more inventory.\r\n\r\nFor most companies, service levels float somewhere between 90 and 100 percent. For instance, if your service level is 92 percent, you\u2019re saying you want to fulfill orders for this product at least 92 percent of the time.\r\n\r\nOnce you have decided on your desired service level, you need to express it as a factor. You can convert your factor by using a formula in Excel (=NORMSINV (X%)) or by referring to a factor table.\r\n\r\n<strong>Our 92% service level expressed as a factor is 1.41.<\/strong>\r\n<h3>Standard Deviation of Lead Time<\/h3>\r\nTo find your standard deviation of lead time, you need access to historical data. The more data the better since you want your standard deviation of lead time to be an accurate reflection of reality.\r\n\r\nWhile businesses have an official lead time from suppliers in their service level agreements, the exact number can vary from time to time. Some suppliers exceed expectations. If their SLA says 5 days, they more often than not deliver within 2 days. Other suppliers occasionally deliver late.\r\n\r\nThe standard deviation helps you express how reliable your suppliers actually are, so you can better calculate your buffer stock. This is why having ample historical data is helpful.\r\n\r\nLet\u2019s return to our keyboard example. Earlier, we used an average lead time on the assumption that there was no set service level agreement with our supplier.

Then, add up all the deviations to find the standard deviation.\r\n\r\nYour standard deviation = 5.\r\n\r\nThen, divide your standard deviation by the number of orders (9) which gives you a standard deviation of 0.56.\r\n\r\nAdd this to your expected lead time of 15.\r\n\r\n<strong>Your standard deviation of lead time is 15.56 days.<\/strong>\r\n<h3>Demand Average<\/h3>\r\nTo calculate your demand average, choose a time period, determine how much product you sell in that time period, add up your units, and divide by the number of days in the time period. <a href=\"\/blog\/demand-forecasting-retail\" rel=\" noopener\">Demand forecasting<\/a> strategy is an advance way to calculate future demand of your products as well.\r\n\r\n<strong>If you sell 2,400 units in 30 days, your demand average would be 80.\u00a0<\/strong>\r\n\r\n<!-- In-Page Optin Box -->\r\n<p class=\"in-content-optin\"><strong>FREE DOWNLOAD:<\/strong> Before you read further,\u00a0our team has put together a simple ABC calculation\u00a0excel\u00a0that helps you identify fast and slow moving products.

There are several inventory management practices that are unavoidably labor intensive, like conducting annual counts or cycle counts, so it\u2019s important to automate whenever possible. Calculating inventory reorder points, tracking inventory levels and placing orders can be effectively automated using warehouse and inventory management software.\r\n\r\nUsing inventory reorder points as part of your inventory management strategy also helps you keep your distribution costs low. Some businesses who run their operations from <a href=\"https:\/\/www.logiwa.com\/blog\/multi-warehouse-management\">multiple warehouses<\/a> use the location of their warehouses as a strategy for cost savings.\r\n\r\nFor instance, their order management system's <a href=\"\/blog\/smart-order-routing\" rel=\" noopener\">order routing<\/a> module identifies the delivery address for a customer and then pushes the order to the warehouse closest to that customer.\r\n\r\nThis way, the business saves on transportation costs. If reorder points don\u2019t automatically trigger a purchase order, warehouses can no longer take advantage of this cost-saving strategy since the warehouse closest to a customer may be out of stock.","_et_gb_content_width":"","content-type":"","inline_featured_image":false,"_lmt_disableupdate":"no","_lmt_disable":"no","footnotes":""},"categories":[55,36],"tags":[],"class_list":["post-1218","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-retail","category-wms"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v19.1 (Yoast SEO v25.2) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Reorder Points (ROP) | Logiwa | WMS<\/title>\n<meta name=\"description\" content=\"Reorder point (ROP) is an important asset for inventory.
