Customer Acquisition Cost (CAC)

Customer Acquisition Cost (CAC) represents the total investment required to convert a prospect into a paying customer. It includes all marketing spend, sales team costs, onboarding expenses, and any tools or technology used in the acquisition process.

CAC is calculated by dividing the total acquisition costs during a period by the number of new customers acquired in that same period. For example, if you spent $100,000 on sales and marketing in a quarter and acquired 200 new customers, your CAC is $500.

CAC is most meaningful when compared to Customer Lifetime Value (CLV). The CLV:CAC ratio indicates the return on your acquisition investment. A ratio below 1:1 means you are losing money on every customer. A ratio of 3:1 or higher is considered healthy for most SaaS businesses.

Reducing CAC does not always mean spending less. It can mean spending more efficiently—improving conversion rates, leveraging customer referrals (from Promoters identified through NPS), optimizing channel mix, and reducing the sales cycle through better product demos and content.
