Inventory Planning
Reorder Point Visualizer
See how inventory depletion, lead time and safety stock determine the point where a replenishment order should be placed.
Reorder point and safety stock
Adjust the assumptions and watch the order point move.
Reorder point120 units
Order day7.0
Arrival day11.0
Inventory at arrival40
ROP = dL + SS = (20)(4) + 40 = 120 units
Order day = (Iā ā ROP) / d = 7.0
Order day = (Iā ā ROP) / d = 7.0
This simple model assumes constant daily demand and a fixed lead time.
