Blended CAC

Blended CAC is a metric used to understand the overall customer acquisition costs of your ecommerce business, which can help you optimize marketing targets and strategy.

Blended CAC (Customer Acquisition Cost) is a key metric used by ecommerce businesses to get an understanding of how much money they are spending to acquire customers. It estimates the average cost to acquire new customers through marketing and advertising initiatives. Blended CAC measures the total cost of customer acquisition activities (such as marketing campaigns, advertising, sales efforts, etc.), divided by the total number of customers acquired in a specific time period. This allows ecommerce businesses to see the impact of marketing and advertising campaigns on sales, and adjust their strategies accordingly.


Blended CAC = (Total Marketing and Sales Expenses) / (Total Number of Customers Acquired)


Let's consider an ecommerce company that operates in the fashion industry.

For this example:

  • The Total Marketing and Sales Expenses incurred during a specific period (e.g., a month) amount to $50,000.
  • The Total Number of Customers Acquired during the same period, including both new and existing customers, is 1,000.

To calculate the Blended CAC:

Blended CAC = $50,000 (Total Marketing and Sales Expenses) / 1,000 (Total Number of Customers Acquired)

Blended CAC = $50

In this example, the Blended Customer Acquisition Cost (CAC) for the ecommerce company is $50. This means that on average, the company spent $50 to acquire each customer during the specified period.

Why is Blended CAC important?

Blended CAC provides an understanding of the overall costs associated with acquiring new customers for an ecommerce business. This metric helps ecommerce businesses identify the most effective marketing and advertising channels and evaluate cost efficiencies based on the return on investment of each campaign. By knowing the Blended CAC for each channel, it allows the business to optimize its marketing budget and allocate it to the best-performing channels.

Which factors impact Blended CAC?

The factors that directly affect Blended CAC include customer lifetime value, pricing strategies, customer segmentation, advertising costs, and customer attrition. Additionally, there are market forces such as competition and industry trends that have an indirect impact on Blended CAC.

How can Blended CAC be improved?

Improving Blended CAC is all about optimizing customer acquisition costs and driving more sales volume. Strategies to improve Blended CAC include increasing customer lifetime value, optimizing advertising spend, leveraging churn reduction, and leveraging customer segmentation.

What is Blended CAC's relationship with other metrics?

Blended CAC is an indicator of how efficient your customer acquisition costs are. It is often used in combination with other ecommerce metrics such as customer lifetime value (LTV) and customer churn rate, to better understand the effectiveness of customer acquisition campaigns.

A low Blended CAC compared to LTV is a sign of a successful campaign, while a high Blended CAC is a sign that something needs to be adjusted.
