Safety stock = Z * sqrt { (Average lead time * (Standard deviation of demand) ² + (Average sales * Standard deviation of lead time) ² } This formula takes into account variations in supply and demand. examples of safety stock calculations You can download this safety stock excel template here: Safety Stock Excel Template

In this case this would mean holding about 18 units (the standard deviation of 11 x 1.65) of stock, i.e. 38 units in total (project request mean + safety stock). Heres how Z-scores relate to the likelihood that youll be able to meet demand: [6] Consider lead time to account for supply variability. Out of stock refers to changes in customer demand (usually when demand is higher than expected for a given product), incorrect forecasting of supply and demand, or variability in delivery times raw material.

What factors determine the demand for safety stock?
