How to Calculate Customer Acquisition Cost in Xero

Making the most of your Xero data

What is Customer Acquisition Cost?

Customer Acquisition Cost (CAC) is the total cost it takes to acquire a new customer. CAC is calculated by dividing the total cost of acquiring a new customer by the number of new customers acquired during that time period.

CAC is a broad metric that is used to determine how much it costs your company to acquire a new customer. This metric is used to determine whether or not your company is spending too much money on acquiring new customers.

CAC is calculated on a per-customer basis, and is usually calculated on a monthly basis.
