What is customer acquisition cost?
Customer Acquisition Cost (CAC) is the average amount a business spends on sales and marketing to acquire a single new customer. It’s a core efficiency metric for growth planning and budgeting.
How this calculator works
Enter your total sales and marketing spend for a period and the number of new customers acquired in that same period. CAC is calculated by dividing total spend by the number of new customers.
For a fuller picture, businesses often compare CAC against customer lifetime value (LTV) — a healthy business typically wants LTV to be several times higher than CAC. This tool is for general business planning purposes.
