What are Units per Transaction (UPT)

Units per Transaction (UPT), also known as Items per Customer (IPC), is a key performance indicator (KPI) that measures the average number of items purchased in a single transaction. It is calculated by dividing the total number of units sold by the total number of transactions over a specific time period. Commonly used in the retail sector, UPT helps businesses understand customer purchasing behavior, with higher UPT values indicating that customers are buying more items per visit. Monitoring this metric can aid in optimizing sales strategies, upselling efforts, and overall transaction value.
