12-Month MRR Projection

How to Interpret These Numbers

  • Healthy runway: 12+ months gives you room to iterate. Under 6 months means you need to cut costs or raise capital soon.
  • LTV:CAC ratio: A ratio of 3:1 or higher is considered healthy. If LTV is less than 2x CAC, your acquisition costs are too high.
  • CAC payback: Under 12 months is good for SaaS. Under 6 months is excellent — you're recovering acquisition costs quickly.
  • Net burn: If MRR exceeds operating costs, you're profitable and runway is effectively infinite. Reinvest profits into growth.
  • Churn impact: Even 5% monthly churn caps your growth. Reducing churn from 5% to 3% can double your LTV.
