What is Customer Acquisition Cost (CAC) Calculator?

Customer Acquisition Cost is the total amount you spend on sales and marketing divided by the number of new customers you gain. It is one of the most important metrics for any growth-focused business, revealing whether your customer acquisition strategy is efficient or unsustainable.

How to Use This Tool

1. Add up all marketing and sales expenses for a given period (ads, salaries, tools, events). 2. Enter the total number of new customers acquired in that same period. 3. Click calculate to get your CAC.

💡 Pro Tip: Calculate CAC separately per channel — Google Ads, social media, referrals, content. You will almost always find one channel acquiring customers at a fraction of the cost. Double down there. Use this calculator to run the numbers after every campaign!
