CAC Formula
CAC Calculation
How to calculate customer acquisition cost
Basic Formula:
- CAC = Total Acquisition Costs ÷ Number of New Customers
- Total costs include marketing, sales, and related expenses
- Time period should be specified (monthly, quarterly, annual)
- Focus on new customers only
Components:
- Advertising and marketing spend
- Sales team salaries and commissions
- Marketing technology and tools
- Content creation and distribution
- Lead generation and nurturing
Customer Lifetime Value (CLV)
CLV Formula:
- CLV = Average Revenue per Customer × Customer Lifetime
- Also: CLV = (Average Order Value × Purchase Frequency) × Customer Lifespan
- Measures total customer value
- Essential for CAC comparison
LTV:CAC Ratio:
- Ideal ratio: 3:1 or higher
- 3:1 means customer is worth 3x acquisition cost
- Lower ratios indicate unsustainable acquisition
- Higher ratios show efficient marketing
Industry Benchmarks
| Industry | Average CAC | LTV:CAC Ratio | Key Drivers |
|---|---|---|---|
| SaaS/Software | $150-300 | 3:1 - 5:1 | Sales cycles, competition |
| E-commerce | $50-150 | 3:1 - 4:1 | Advertising, SEO |
