What is the average spend per customer?
Average spending per customer is the amount each customer spends at your business, on average, when you add up all their purchases over a given period.

Average spending per customer focuses on the individual, not the order. It adds up all the purchases each customer made during a given period and calculates the average.
It differs from the average order value: a customer may have low order values but shop very frequently, and thus spend more over the course of a year than someone who makes a single purchase with a high order value.
Why does it matter?
This metric combines two factors: how much each customer spends per purchase and how often they return. That's why it's a great indicator of the quality of your relationship with your customers.
If it goes up, your customers trust you more and choose you more often. If it goes down, you may be attracting customers who make a one-time purchase and don't return. It's also a starting point for estimating LTV (customer lifetime value).
How is it calculated?
Formula: Average spending per customer = Total sales for the period / Number of unique customers who made a purchase.
For example, if you sell $100,000 to 1,000 different customers in a year, the average spending per customer is 100,000 / 1,000 = $100.
Story mode
Lucía shops at an online sports store four times a year: sneakers, clothing, accessories, and a gift. Each order is around $50, so she spends $200 a year. Pedro made a single purchase of $120. Although Pedro’s order was larger, Lucía is more valuable to the store.
