How to calculate safety stock
This calculator finds safety stock — a buffer inventory level to protect against demand or lead time variability — by multiplying maximum daily sales by maximum lead time.
How the calculation works
Safety stock = Maximum daily sales × Maximum lead time days.
Example
30 units maximum daily sales with a 10-day maximum lead time: 30×10 = 300 units.

Pro Tips for Safety Stock
- This is a simplified safety stock formula based on maximum values — more sophisticated methods incorporate demand variability statistically for a more precise (often smaller) buffer.
- Recalculate periodically as sales patterns or supplier lead times change, since both directly affect the appropriate safety stock level.
Common Safety Stock Mistakes to Avoid
- Using average (rather than maximum) daily sales and lead time, which would understate the safety buffer needed to protect against worst-case scenarios.
