Safety stock is inventory that the company prepares to prevent a shortage of inventory when market demand conditions are uncertain.

The Importance of Safety Stock in Business
The safety stock aims to gain profit, anticipate fluctuation demand, and facilitate production schedules. Market conditions will affect the law of supply and demand. If market conditions are always dynamic, the company will implement this system to anticipate changes in market conditions and take more profits. It aims to determine the right inventory. If the inventory is too large, the circulation of money will stop in trading capital. Conversely, if the inventory is too small, the company will experience a stock out.
Factors that cause stock-outs are demand fluctuations, inaccurate forecasts, as well as varying lead times. Therefore, this is necessary to help minimize stock-outs, by comparing the number of service levels that are in accordance with stock-outs. This can also have an impact on deviations from the previously planned schedule. For example, if the company determines the service level is 98%, then the remaining 2% are purchase orders from stock out and only 98% can be processed. You can get that from the formula for calculating safety stock. You can also use the ERP system to facilitate company operations.

How to Calculate Safety Stock
In determining the service level, you can see the SS formula based on actual demand data. Furthermore, the calculation of the standard deviation needs to be multiplied by the safety factor. Here’s the complete formula:
Safety stock = safety factor × standard deviation or, Safety stock = Z×√((PC/T)×σD)
Description:
Z = safety factor
PC = performance cycle (forecast cycle and order cycle)
D = standard deviation
T = cycle period of demand
The steps for calculating safety stock are divided into several stages. In the first step, you need to calculate the maximum sales and daily average sales. Then, calculate the maximum wait time and the daily average wait time. After that, enter the formula:
Safety Stock = (Max daily sales × Maximum lead time) – (Average daily sales × Average lead time)
The formula is from reordering points and is useful when market changes occur over a long period of time (≥ 2 years). You can improve this reorder point calculation by compiling an income statement every 3 months.
