About the Lead Time Calculator

Lead time is the total elapsed time between placing an order and receiving it, made up of processing (time to prepare or manufacture) and shipping (time in transit).

Formula: Total Lead Time = Processing Days + Shipping Days; Delivery Date = Order Date + Total Lead Time

Useful for setting customer delivery expectations, planning inventory reorders, or figuring out the latest date you can order something and still have it arrive in time.
