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.
Example Calculation
A product sells 35 units per day on average, and the supplier lead time is 14 days.
- 01Lead Time Demand = 35 x 14 = 490 units
- 02Weekly Demand = 35 x 7 = 245 units
- 03You need at least 490 units on hand when placing an order to last until delivery.
