Supply Chain
Bullwhip Effect Calculator
Quantify how demand variance amplifies as orders move upstream through multiple supply chain tiers—the bullwhip effect. Use it to identify how forecasting methods, batch sizes, and lead times magnify instability.

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.
