How it’s calculated
- Safety stock = (max daily sales × max lead time) − (average daily sales × average lead time).
- Reorder point = (average daily sales × average lead time) + safety stock.
- Reorder now? = Yes when on hand is at or below the reorder point.
- Days of stock left = units on hand ÷ average daily sales.
- Units round up; days round down.
What a good number looks like
There’s no single right number. Aim to cover busy days and late deliveries without tying up cash.
