How this is calculated
Uses the standard 'maximum minus average' safety-stock formula: the gap between your worst-case demand-during-lead-time and your average demand-during-lead-time is the buffer you need to hold.
Safety stock = (Max daily sales × Max lead time) − (Avg daily sales × Avg lead time). Reorder point = (Avg daily sales × Avg lead time) + Safety stock. This is the standard beginner/intermediate formula; enterprise operations with highly variable demand should use a statistical (service-level/z-score) model instead.
