LTV:CAC Benchmarks
How to reduce CAC
- • Improve conversion rates — optimize landing pages and signup flows
- • Invest in organic channels — SEO, content marketing, and referrals have lower CAC long-term
- • Email marketing has one of the lowest CACs at $1-5 per acquisition via lead magnets
- • Reduce sales cycle length — shorter cycles mean lower cost per deal
- • Focus on retention — it is 5-25x cheaper to retain a customer than acquire a new one
About this tool
Customer Acquisition Cost is how much you spend to win each new customer. Tracking CAC alongside lifetime value reveals whether your growth is profitable or you're buying customers at a loss. The LTV:CAC ratio is one of the most important SaaS metrics — investors look for 3:1 or better. Use our email ROI calculator to find your lifetime value, and our MRR calculator to understand revenue impact. Email marketing typically has the lowest CAC of any channel — measure it with our email ROI calculator and optimize with our conversion rate calculator.
