Reorder Point = (Average Daily Usage × Lead Time) + Safety Stock
- Average daily usage. Units you sell or use each day.
- Lead time. Days from order to delivery.
- Safety stock. The extra cushion you choose.
This reorder point formula tells you exactly when inventory hits your safety net—no more knee-jerk orders or stockouts.
Reorder Point Example
Your tea shop moves 80 bags a day. Supplier lead time is 7 days. You keep 50 bags in reserve.
