## How to Calculate Lead Time Demand
### Formula
**Lead Time Demand = Average Daily Demand x Lead Time (days)**
Lead time demand is the inventory you will consume between placing an order and receiving it. If you sell 35 units per day and your supplier needs 14 days to deliver, you must have at least 490 units available when you place the order (plus safety stock). This calculation is the foundation of reorder point planning.

Exemple Résolu
A product sells 35 units per day on average, and the supplier lead time is 14 days.
- Lead Time Demand = 35 x 14 = 490 units
- Weekly Demand = 35 x 7 = 245 units
- You need at least 490 units on hand when placing an order to last until delivery.
