Definition
Total cost to acquire a new customer.
Sales and marketing acquisition cost divided by new customers.
“When someone uses “CAC,” ask what rule, owner, or outcome they mean in this system.”
The fuller explanation
Understanding CAC
CAC is a practical concept in measurement, analytics, and attribution. Put simply, total cost to acquire a new customer. The useful boundary is what the term changes about a decision, owner, or system behavior.
In practice, teams should define the inputs, expected outcome, owner, and exceptions. A concrete example is: Sales and marketing acquisition cost divided by new customers. The exact implementation will depend on the organization’s tools and operating model.
The term becomes operational only when people can observe it consistently and act on it. Document the definition, connect it to the relevant workflow or report, and revisit it when systems or responsibilities change.
Common mistakes
- Reporting a metric without its definition.
- Treating correlation or assigned credit as causation.

Questions about CAC
What does CAC mean in marketing operations?
