Core SaaS Metrics

Revenue Metrics

• MRR: sum of all active subscription revenue in a month (normalize all plans to monthly)
• ARR: MRR × 12 (snapshot metric, not cumulative)
• New MRR: MRR from new customers acquired this month
• Expansion MRR: additional MRR from existing customers (upsell, cross-sell)
• Contraction MRR: MRR lost from downgrades
• Churned MRR: MRR lost from full cancellations
• Net New MRR = New + Expansion - Contraction - Churned

Retention Metrics

• Gross Revenue Retention (GRR) = (MRR_start - Churned_MRR - Contraction_MRR) / MRR_start
  • Best-in-class: > 90% (enterprise), > 80% (SMB)
• Net Revenue Retention (NRR) = (MRR_start + Expansion - Contraction - Churned) / MRR_start
  • Best-in-class: > 120% (expansion-led), > 100% (minimum for growth)
  • NRR > 100% means revenue grows even with zero new customers

Efficiency Metrics

• CAC = Total Sales & Marketing Spend / New Customers Acquired (same period, lagged by sales cycle)
• LTV = ARPU × Gross Margin / Monthly Churn Rate
• LTV/CAC: > 3x healthy, > 5x excellent, < 1x unsustainable
• CAC Payback Period = CAC / (ARPU × Gross Margin %): target < 12 months

SaaS Efficiency Score (Rule of 40)

Rule of 40 = YoY Revenue Growth % + EBITDA Margin %

• 40: strong (growth + profitability balanced)

• 60: exceptional

• < 20: concerning

Magic Number (Sales Efficiency)

Magic Number = Net New ARR (quarter) / Prior Quarter S&M Spend

• 0.75: efficient go-to-market

• < 0.5: investigate unit economics before scaling spend
