Inventory management and operations are always at risk due to unpredictable variables. So, is there any way to avoid that risk?

Today's article will discuss how using safety stock is beneficial to reduce your inventory and operations risk.

What is Safety Stock?

Safety stock is the extra quantity you hold in your inventory to avoid running out of products in unexpected situations. Many scenarios, such as rapid weather changes or a celebrity's social media post, can sudden increase customer demand and quickly deplete inventory. Although there is a risk of the excess product becoming dead stock, ordering extra amounts also give other benefits like price negotiations (economies of scale) and improve sustainability measures (less waste and transportation miles). Considering how the most sold out items can be one of the fastest ways to lose your customers, safety stock is something you should consider.

Safety stock keeps customers satisfied by maintaining a steady stock level. The addition inventory helps with ordering more items if your company makes a demand forecast error or underestimates popular items. You do not have to worry about relying on your suppliers to quickly deliver goods or turn away customers due to a low inventory level if you have enough safety stock.

Let us now check out how you can adopt safety stock to your business.

Importance of Safety Stock

  • Protection against unforeseen supply variation - The main goal of safety stock is to keep enough inventory on hand in case of unexpected shortages. Because shortages can happen due to various reasons, it is recommended to keep extra stock in the back to be prepared. Especially if your items consist of non-perishables, keeping a safety stock is highly recommended.
  • Avoid stock-outs to maintain customer satisfaction - Most importantly, safety stock has the potential to play a significant role in meeting customers' needs. Managing inventories and avoiding stock-outs provides ample supply to satisfy loyal customers. Therefore, keeping a surplus of quantity as safety stock can help the company to manage customer satisfaction.
  • Inaccurate demand estimation - Although predicting inventory based on customer demand is crucial for all businesses, accurately forecasting for inventory management does not always work. Even if a company has experience or not, there is still a margin of error where prediction might not be successful. Therefore, it is recommended for businesses to be aware of tracking safety stock levels.
  • Prevention against price fluctuations - Restocking inventories in an emergency will cause additional expenses since factories, shipment, and management must be rushed. Aside from this, once market price changes, it can cause the cost of your goods to increase unexpectedly. This results in a lack of raw material prices, unexpected market demand increases, and new competitors. If you have enough safety stock during these unforeseen situations, you may avoid the higher costs of item buying price without losing sales.

Calculating Safety Stock

Although there are many ways to calculate Safety Stock, the general safety stock formula will helps you find out the optimal number of products that you must maintain.

General equation
Safety Stock = (Max Daily Sales x Max Lead Time in Days) - (Average Daily Sales x Average Lead Time in Days)

* Lead Time is a product’s manufacturing time from the beginning to the end.

Let us look at the example below to understand the calculation of safety stock.

Company A is running an accessory store. It takes on an average lead time of 4 days and a maximum of 6 days to make an accessory. The average daily sales of the accessories are 20 pieces and a maximum of 30 pieces.
Example of statistics used to calculate Safety Stock
Example of safety stock formula

If we put the above values to the safety stock equation of the above, (30 x 7) – (20 x 4) = 130. As a result, company A will need a safety stock of 130 units.
