How it is calculated
Purchase frequency = number of orders for the period ÷ number of unique customers over that same period. A value of 2.4 means the average customer placed 2.4 orders in the chosen period.
The figure needs to be measured over a specific period — a month, a quarter, a year — and it doesn't scale by simple multiplication: quarterly frequency isn't a third of annual frequency, because the set of active customers usually isn't the same across periods.
This is the exact figure used as "purchases per year" in the LTV calculation — measuring it from actual sales data instead of guessing makes the customer lifetime value estimate more accurate.
