CAC represents how much a business spends to acquire each new customer. It includes all marketing, sales, and related costs divided by the number of customers acquired.
CAC = (Total Sales + Marketing Costs) ÷ Number of New Customers
Costs include: advertising spend, marketing salaries, sales team salaries, software and tools, creative production, and agency fees.
Calculate CAC by individual channels (paid search, social media, content marketing) to identify the most cost-effective acquisition strategies.
A healthy business has a CLV:CAC ratio of 3:1 or higher, meaning a customer generates at least 3x what it cost to acquire them.
Lower CAC by improving conversion rates (getting more from existing traffic), optimizing targeting (reaching better-fit prospects), enhancing content (converting with valuable content), leveraging referrals (lower-cost acquisition), and improving retention (reducing the need for constant acquisition).
CAC varies widely by industry. SaaS companies typically target CAC payback periods of 12-18 months.
