For a reproducible inventory reorder point calculator example, use Average daily demand: 100; Lead time days: 7; Safety stock units: 300. The first returned value, reorder point, is calculated with averageDailyDemand*leadDays+safetyStock; the other results describe the same scenario. Change one input at a time and keep its unit consistent when comparing scenarios.
