Understanding CAC

Customer Acquisition Cost (CAC) is one of the most critical metrics for startup success. It represents the total cost of acquiring a new customer, including marketing, sales, and related expenses.

Calculating Your CAC

CAC = (Total Sales + Marketing Costs) / Number of New Customers Acquired

Track this metric monthly and by channel to understand which acquisition strategies are most efficient.

Strategies to Reduce CAC

  • Optimize your conversion funnel
  • Focus on high-performing channels
  • Improve targeting and segmentation
  • Leverage content marketing and SEO
  • Build referral programs
  • Automate where possible

The CAC:LTV Ratio

Your Customer Lifetime Value should be at least 3x your CAC. If it's lower, you need to either reduce acquisition costs or increase customer value.

Channel-Specific Optimization

Different channels have different CACs. Test multiple channels, measure rigorously, and double down on what works while cutting what doesn't.
