Key SaaS metrics include MRR, churn rate, LTV, CAC, and NRR. Each provides insights into growth, retention, and unit economics for data-driven decisions.
Calculating B2B SaaS metrics correctly is crucial for understanding business health and making informed decisions. Here are the essential calculations:
Monthly Recurring Revenue (MRR): Sum of all monthly subscription revenue. Annual contracts should be divided by 12.
Churn Rate: (Customers lost in period / Customers at start of period) × 100. Calculate both customer and revenue churn separately.
Customer Lifetime Value (LTV): Average Revenue Per User × Gross Margin % ÷ Monthly Churn Rate. This shows total value from a customer relationship.
Customer Acquisition Cost (CAC): Total sales and marketing expenses ÷ Number of new customers acquired in the same period.
LTV:CAC Ratio: Should be 3:1 or higher for healthy unit economics.
Net Revenue Retention (NRR): (Starting MRR + Expansion - Downgrades - Churn) ÷ Starting MRR × 100. Best-in-class SaaS companies achieve 120%+ NRR.
Annual Recurring Revenue (ARR): MRR × 12, useful for larger deals and annual planning.
Track these metrics monthly in dashboards, segment by customer cohorts, and benchmark against industry standards. Focus on trends rather than absolute numbers to identify patterns and opportunities.
