Janitorial Supply Reorder Point Calculator

Estimate the stock quantity that should trigger a reorder from observed daily use, supplier lead time, and user-entered safety stock.

Enter Average daily usage (units/day), Order-to-available lead time (days), Chosen safety stock (units) to calculate Expected use during lead time (units), Reorder trigger quantity (units), Coverage represented by reorder point (days).

Professional example: Setting a reorder quantity for a frequently used supply SKU. The example inputs remain editable and must be replaced with current site or product data before operational use.
