CAC (Customer Acquisition Cost) is the total cost of acquiring a single new customer, including marketing, sales, and onboarding expenses.
CAC = (Total acquisition costs) / (Number of new customers). Healthy SaaS businesses target CAC payback < 12 months and LTV:CAC ratio of 3:1 or better. Modern attribution challenges (multi-touch, dark funnel) make CAC measurement increasingly difficult. By 2026, CAC for B2B SaaS averages $500-5,000 depending on ACV.
CAC is the cost side of the unit-economics equation. Without it (and a comparison to lifetime value), it is impossible to tell whether scaling acquisition will create or destroy value.
A SaaS startup spends $50,000 on marketing and sales in a quarter and acquires 100 paying customers. Their blended CAC is $500. The team then segments CAC by channel to see which acquisition path is actually paying off.
CAC is not just ad spend divided by new customers. It includes fully loaded sales and marketing costs — salaries, tools, content production, and overhead — not just media costs.
Compute fully loaded CAC by channel, not just blended; an averaged number hides which channels are sustainable and which are quietly losing money.
