What is Customer Acquisition Cost (CAC)?
Customer Acquisition Cost (CAC) represents how much your company spends to acquire a single paying customer. It helps you understand how efficiently your sales and marketing efforts convert prospects into customers.
CAC = Total Sales & Marketing Spend ÷ Number of New Customers Acquired
For example, if you spent €10,000 last month and gained 200 new customers, your CAC is €50 per customer.
Why CAC Matters for SaaS?
A sustainable SaaS business depends on maintaining a healthy balance between acquisition cost and customer lifetime value (LTV).
When your CAC is too high, you’re spending more to acquire customers than they’re worth. When it’s efficient, your marketing scales profitably.
