What is customer acquisition cost (CAC)?

CAC measures the average sales and marketing cost of acquiring a new customer. It helps you evaluate acquisition efficiency and compare customer value with the cost of winning business.

How to use this tool

CAC = sales and marketing spending ÷ new customers acquired. Match the period and channels for both inputs. Include the costs relevant to your definition, such as advertising, salaries, software, and creative production.

Example

$10,000 spent acquiring 200 new customers gives a CAC of $50 per customer.

Understanding your result

Use new customers rather than leads or total active accounts. Long sales cycles can separate spending from the resulting sales. Lower CAC is useful only when customer quality, margin, and retention remain healthy.
