Customer Acquisition Cost (CAC) measures the total amount a business spends to acquire a new customer.

CAC is one of the most important growth metrics because it helps determine whether customer acquisition efforts are financially sustainable and scalable.

CAC Calculator example

Suppose your company spends $12,000 on marketing and $3,000 on sales activities during a month. If you acquire 100 new customers, your CAC is $150. If the average customer generates $600 in lifetime value, your LTV:CAC ratio is 4:1. That ratio may be attractive if margins, payback period, retention, and cash flow support continued acquisition.
