Transparent method
How this calculation works
Expected lead-time demand equals daily demand multiplied by lead days. Safety stock is added to produce the reorder point.
Useful output
What you receive
Reorder point, lead-time demand, current stock gap, status signal, assumptions, and CSV.
Decision guardrail
What this does not decide
Averages can hide demand spikes and supplier delays; a reorder point is not an order quantity.
