About cac calculator
Customer acquisition cost (CAC) is what you spend, on average, to win one new customer.
Formula
CAC = sales and marketing spend ÷ new customers won. ₹3,00,000 spent to win 150 customers gives a CAC of ₹2,000.
Payback period
Payback = CAC ÷ monthly gross profit per customer. A shorter payback means faster recovery of what you spent.
A worked example
A company spends ₹5 lakh on marketing and sales in a month and gains 250 customers, so CAC is ₹2,000. If each customer brings ₹500 a month in gross profit, the payback period is 4 months.
Include all costs
Count ad spend, salaries of sales and marketing staff, tools and agency fees. Leaving out salaries makes CAC look lower than it really is.
Blended and paid CAC
Blended CAC divides all spend by all new customers, including those who came for free. Paid CAC counts only customers from paid channels. Track both to see how much organic growth helps.
