Out of stock at the store level means a given, normally stocked product is not available at a specific time.
Out-of-stocks (or stock-outs) quantify the number of retail outlets where an item is expected to be available for customers but is not. It is typically expressed as a percentage of stores that list the relevant item.
Out-of-stocks (%) = Outlets Where Brand or Product is Listed But Unavailable (#) ÷ Total Outlets Where Brand or Product is Listed (#)
In addition, three outlet weighting methods can be applied to the calculation:
- Numeric – outlets are unweighted
- ACV (all commodity volume) – outlets weighted by total sales of all commodities
- PCV (product category volume) – outlets weighted by sales of a specific product category, such as toilet paper
