How to calculate the proportion of customer bill cost?

The calculation formula of customer unit price is: customer unit price = total sales ÷ total customers, or customer unit price = total sales ÷ total number of transactions.

The essence of customer unit price is that in a certain period, the average price of each customer's consumption leaves the range of "a certain period", so the index of customer unit price is meaningless.

The retail term is also called ATV, that is, the average quantity of goods purchased by each customer. (1) customer unit price = average unit price of goods × average quantity of goods purchased by each customer (2) customer unit price = line length × retention rate × attention rate × purchase rate × purchase quantity × unit price of goods.
