What is CAC and how is it calculated?

Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer, including all marketing and sales expenses. It's calculated as: CAC = Total Marketing & Sales Costs ÷ Number of New Customers Acquired. This metric helps businesses understand the efficiency of their customer acquisition efforts.

What costs should be included in CAC calculations?

CAC should include all customer acquisition expenses: advertising spend, marketing team salaries, sales commissions, software/tools for marketing/sales, content creation costs, agency fees, and overhead allocated to customer acquisition. Some businesses also include portions of product development or customer support costs.

What is a good CAC for my business?

A 'good' CAC depends on your industry, business model, and customer lifetime value (LTV). Generally, SaaS companies aim for CAC under $300-500, e-commerce under $50-100, and B2B services vary widely. The key metric is LTV:CAC ratio - aim for at least 3:1, meaning a customer is worth 3x their acquisition cost.

What's the difference between CAC and CPA?

CAC (Customer Acquisition Cost) measures the cost to acquire a paying customer, while CPA (Cost Per Acquisition/Action) typically refers to the cost of any conversion action (lead, sign-up, download). CAC is a subset of marketing metrics focusing specifically on customer acquisition, while CPA can apply to various conversion goals.
