Supply Chain
Lead Time Demand Calculator
Estimate the total units expected to be consumed during the lead time of a replenishment order by multiplying average daily demand by lead time in days. This figure is the baseline for calculating reorder points and safety stock requirements.

Supply Chain
Reorder Point Calculator
Compute the inventory level at which to place a replenishment order, combining expected demand during lead time with a safety-stock buffer. Useful for setting auto-reorder triggers in ERPs, WMS systems, and lean inventory policies.
