Customer Acquisition Cost (CAC)
Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer, including all sales and marketing expenses divided by the number of new customers acquired in a given period. CAC is a fundamental unit economics metric that determines whether a business model is financially sustainable. GTM efficiency improvements — better ICP targeting, more resonant messaging, shorter sales cycles — directly reduce CAC. The relationship between CAC and Customer Lifetime Value (CLV) is the most important financial metric in GTM strategy evaluation.
Why It Matters
CAC is the efficiency metric for the entire GTM motion. When CAC is too high relative to CLV, the business model is unsustainable regardless of revenue growth. GTM improvements that reduce CAC — better targeting, more resonant messaging, shorter sales cycles — have direct and compounding impact on unit economics and long-term business viability.
Example
A SaaS company calculates its CAC at $18,000 per customer with a CLV of $42,000 — a 2.3:1 LTV:CAC ratio below the 3:1 benchmark considered healthy. By improving ICP targeting and reducing sales cycle length, they reduce CAC to $11,000 within 18 months.
