Why CAC Matters
Customer Acquisition Cost (CAC) is the total cost of acquiring a new customer, including all marketing and sales expenses. Understanding your CAC is essential for sustainable growth and profitability.
How to Calculate CAC
Blended CAC = (Total Marketing Spend + Total Sales Spend) / New Customers Acquired
For channel-specific CAC, divide channel spend by customers acquired through that channel.
CAC Optimization Strategies
- Improve conversion rates: Better landing pages and sales processes reduce CAC
- Channel mix optimization: Shift budget to more efficient channels
- Referral programs: Incentivize customers to bring in new customers cheaply
- Content marketing: Build organic acquisition for lower long-term CAC
The CAC:LTV Ratio
- 3:1 or better: Healthy unit economics, room for growth investment
- 1:1 to 3:1: Optimize CAC or improve retention before scaling
- Below 1:1: Losing money on each customer, requires urgent attention
