What is Blended CAC?

Short answer: CAC calculated across all acquisition channels combined, including organic and paid, rather than isolating a single channel.

Definition

CAC calculated across all acquisition channels combined, including organic and paid, rather than isolating a single channel.

Why it matters for growth

Blended CAC prevents founders from over-crediting one channel; it is the number investors ask for because it reflects total spend against total new customers.

Example

A company spending on ads, content, and one salesperson divides total spend by total new customers to get a single blended figure.
