How to Analyze Your SaaS Metrics
Check your churn rate

Project your ARR
Once you know your churn, model growth-adjusted ARR projections. See where you'll be in 12 months at your current trajectory.
Measure unit economics
CAC, LTV, and the LTV:CAC ratio tell you whether each customer you acquire is profitable. A ratio above 3:1 means your unit economics work.
