Frequently Asked Questions
How is safety stock calculated?
This calculator uses the statistical formula Safety Stock = Z-score x Demand Standard Deviation x Square Root of Lead Time, assuming lead time itself is stable and only demand varies.
What does the service level percentage mean?
The service level is the probability of not running out of stock during the lead time. A 95% service level means you accept roughly a 5% chance of a stockout before your next delivery arrives.
