└─────────────────────────────────────────────────────────────┘Calculations:
mrr_metrics:
# Monthly Recurring Revenue
MRR: sum(all_active_subscriptions.monthly_value)
# Annual Recurring Revenue
ARR: MRR × 12
# MRR Components
new_mrr: sum(new_subscriptions_this_month)
expansion_mrr: sum(upgrades_this_month)
contraction_mrr: sum(downgrades_this_month)
churn_mrr: sum(cancelled_subscriptions_mrr)
reactivation_mrr: sum(reactivated_subscriptions)
# Net New MRR
net_new_mrr: new_mrr + expansion_mrr + reactivation_mrr - contraction_mrr - churn_mrr
# Growth Rates
mrr_growth_rate: (ending_mrr - starting_mrr) / starting_mrr × 100
mom_growth: (current_mrr - previous_mrr) / previous_mrr × 1002. Churn Metrics
churn_metrics:
# Logo Churn (Customer Count)
logo_churn_rate:
formula: customers_lost / customers_start_of_period × 100
benchmark: <5% monthly for SMB, <2% for Enterprise
# Revenue Churn (MRR)
gross_revenue_churn:
formula: churned_mrr / starting_mrr × 100
benchmark: <3% monthly
# Net Revenue Churn (includes expansion)
net_revenue_churn:
formula: (churned_mrr - expansion_mrr) / starting_mrr × 100
target: negative (net expansion)
# Net Revenue Retention (NRR)
nrr:
formula: (starting_mrr - churn + expansion) / starting_mrr × 100

# SaaS Metrics Analysis
## Executive Summary
Your SaaS business is showing healthy growth with some areas for optimization.
### Strengths ✅
- Net Revenue Retention of 108% (above 100% benchmark)
- Quick Ratio of 2.3x (good growth efficiency)
- Enterprise segment showing 97% retention
### Areas to Improve ⚠️
- LTV:CAC ratio at 2.7x (target: >3x)
- CAC payback at 12.5 months (target: <12 months)
- SMB segment churn at 4.5% (target: <4%)
### Recommendations
1. **Reduce CAC**: Focus on lower-cost acquisition channels
2. **Improve SMB retention**: Add onboarding sequences
3. **Expand enterprise**: Higher ARPU, lower churn
4. **Increase expansion revenue**: Upsell/cross-sell programs
