CAC matters because it helps businesses understand how much they need to invest in marketing and sales efforts to grow their customer base. High CAC can limit growth potential, while low CAC indicates efficient acquisition strategies that can support sustainable business expansion.
In practice, CAC is calculated by dividing the total cost of acquiring a new customer (including marketing, sales, and any other expenses) by the number of customers acquired during a specific period. For example, if a company spends $10,000 on marketing efforts to acquire 50 new customers, their CAC would be $200 per customer.
A simple CAC is total sales and marketing spend in a period divided by new customers won in that period; $50,000 spent to win 25 customers is a $2,000 CAC. The number only means something next to lifetime value: a healthy B2B SaaS target is often an LTV:CAC ratio of 3:1 or better with CAC payback under twelve months. Automating CRM hygiene and follow-through cuts the wasted effort that quietly inflates CAC.
