About This Calculator
Customer Acquisition Cost (CAC) measures how much it costs, on average, to acquire a single new customer — combining sales and marketing spend divided by the number of new customers gained in the same period.
How This Is Calculated
CAC = Total Sales & Marketing Spend ÷ New Customers Acquired
$30,000 in spend that acquired 150 new customers gives a CAC of $200 per customer.
Assumptions
- Includes all sales and marketing spend for the period, not just ad spend — salaries, tools, and content costs are often included in a full CAC calculation.
- Assumes the spend and new customers are measured over the same time period.
