What is Lead Time?
Lead time is the total time it takes from placing an order to receiving the finished product. It encompasses all phases of the supply chain, including processing/manufacturing, quality inspection, shipping, and any buffer time. Understanding lead time is critical for inventory management, production planning, and meeting customer expectations.
How to Calculate Lead Time
The lead time formula is: Lead Time = Processing Time + Shipping Time + Inspection Time + Buffer Time. Each component represents a phase in the order-to-delivery cycle. Our calculator adds these components together and shows the total in days and weeks, plus an estimated delivery date based on today.
