The number that tells you if marketing is working
Customer Acquisition Cost (CAC) is the average amount you spend to win one new customer, across all the marketing and sales costs that went into acquiring them. It only means something next to a second number — what that customer is actually worth to you.
Enter your total spend over a period and the number of new customers it brought in to get your CAC. If you also know the average revenue per customer, this calculator shows the ratio between the two — a quick gut-check on whether a campaign or channel is actually paying for itself.
CAC calculator FAQs
CAC = Total Marketing and Sales Spend ÷ Number of New Customers Acquired, over the same period. Spending ₹50,000 to acquire 100 new customers gives a CAC of ₹500.
