What is the reorder point formula?
A common basic formula is average daily usage multiplied by lead time, plus safety stock.
Does this create a purchase order automatically?
No. This calculator only estimates a planning threshold. Purchasing decisions still depend on stock, open orders, supplier constraints and business judgment.
