What is Customer Acquisition Cost (CAC)?
Customer Acquisition Cost (CAC) measures how much it costs to acquire a new customer. It includes all marketing and sales expenses divided by the number of new customers gained during that period. For startups, understanding CAC is critical for fundraising — investors want to see that you can acquire customers efficiently.
CAC Formula
CAC = (Total Marketing + Sales Costs) / Number of New Customers
What is a Good CAC?
A good CAC depends on your LTV (Customer Lifetime Value). The industry benchmark is a LTV:CAC ratio of 3:1 or higher. If your LTV is $900 and your CAC is $300, your ratio is 3:1 — meaning you earn $3 for every $1 spent acquiring a customer.
