Availability percentage is a performance metric that measures the proportion of time a system, service, or product is accessible and functioning as intended. In retail, it often refers to the percentage of products in stock and ready for sale.
Why Availability % Matters
Customer satisfaction: Ensures products or services are consistently accessible.
Revenue protection: Higher availability reduces lost sales opportunities.
Benchmarking: Provides a clear measure for service level agreements (SLAs) and performance targets.
How Availability % Works
The formula varies by context, but a common calculation is:
Actual Available Stock/Total Required Stock times 100
Example:
If 950 out of 1,000 SKUs are in stock, availability % = 95%.
What Availability % Really Tells Us
Availability % is a measure of trust. For customers, it translates into confidence that products will be available for purchase. For businesses, it’s a mirror of how reliable the connections between internal and external teams are. A test of whether buying and merchandising, operations and supply chain are delivering consistently to support trading objectives. Seen through a systems lens, availability % is a narrative about dependability and the success of not just about offering something to purchase, but about ensuring it is there when people what to purchase it.
