Calculate Safety Stock Levels for Efficient Inventory Levels

Inventory management is an important part of running a successful business. A key goal of inventory management is having enough stock to meet customer demand while avoiding excessive inventory buildup. Revenue lost due to stockouts from customers purchasing from competitors and the knock-on effect of reduced supply chain efficiency cannot be underestimated. To help manage your inventory levels correctly managed, it’s vital to calculate safety stock for optimal inventory levels. While common, even desirable, to run low on supply due to increased sales, it is also vitally important to calculate accurate safety stock and reorder cadence to ensure the appropriate amounts of product to keep on hand. In this post we will explore how to calculate safety stock for optimal inventory levels.

Calculate Safety Stock Levels

What is safety stock?

Safety stock is a buffer of inventory kept on hand as an insurance policy to protect against unexpected disruptions in supply or demand. It is essential because it ensures that the company can always fulfill customer orders, even when there are unforeseen delays in receiving goods or a sudden spike in demand. Safety stock also reduces the likelihood of stockouts, which can lead to a loss of sales and customer dissatisfaction. Stockouts result in $984 billion worth of lost sales worldwide, with North American companies alone losing $144.9 billion, according to a study by IHL Group. In addition to preventing stockouts, having safety stock on hand can help a business stay competitive by allowing them to respond quickly to changes in the market and leverage last-minute sales promotions.

Remember that this formula doesn’t consider dramatic fluctuations in lead time or supply chain bottlenecks. Furthermore, it doesn’t account for customer demand fluctuations or seasonal changes. If you need a more accurate safety stock calculation considering these variables, please check out the following methods.

  1. Heizer and Render’s Formula – this method is best if you have significantly varied lead times.
  2. Greasley’s Formula – this method takes into account both lead time and demand fluctuations.
