Straight to the answer

Calculate CAC with two numbers

Customer acquisition cost is the average amount spent to acquire one new customer. Use the same time window and customer definition for both inputs.

How is CAC calculated?

Divide acquisition spend by the number of new customers acquired. Spending $10,000 to acquire 100 customers produces a $100 CAC.

What costs should CAC include?

A fully loaded CAC commonly includes advertising, marketing tools, agency costs, sales compensation, and other acquisition costs. Document your definition and apply it consistently.

Can I calculate channel CAC?
