• Units per transaction (UPT) is a sales metric used to measure the average number of items that customers purchase in any given transaction.

  • The higher the number of units per transaction (UPT), the more products customers buy per visit.
  • Getting people to buy more means that the company understands its customers well. It also means additional income and perhaps more leverage to increase prices and margins. – Retailers often make units per transaction (UPT) a key performance indicator (KPI).
  • Base unit per transaction (UPT) is calculated by dividing the number of items purchased by the number of transactions per period.
  • It is recommended that the number of units per transaction (UPT) be calculated later on a daily basis rather than on a quarterly or seasonal basis for the most accurate data.
