Units Per Transaction (UPT)

Units Per Transaction measures the average number of items a customer purchases in a single order. It is calculated by dividing the total number of units sold by the total number of transactions. UPT reflects the effectiveness of cross-selling, product bundling, and merchandising strategies.

Why Units Per Transaction Matters

Increasing units per transaction is one of the most efficient ways to grow revenue because you are extracting more value from traffic you have already paid to acquire. A rising UPT signals that your product recommendations, bundles, and upsells are working. Tracking UPT alongside average order value helps you understand whether revenue gains are coming from higher-priced items or from customers buying more items per visit.
