Purchase Frequency

Average number of orders placed per customer over a given period.

Purchase frequency indicates how many times a customer orders on average over a given period (typically 12 months). It is a key retention indicator and a direct lever on LTV.

Calculation: Purchase Frequency = Total Number of Orders / Number of Unique Customers.

A frequency of 1.2 means your customers order an average of 1.2 times. The goal is to increase this frequency through cross-selling, loyalty programs, email follow-ups, and personalized offers.

Fullmetrix calculates purchase frequency by RFM segment, by acquisition cohort, and by period to identify the most effective retention levers.
