Churn Analysis Framework
Churn Types
| Type | Definition | Signal |
|---|
| Voluntary | Customer actively cancels | Cancellation request, downgrade |
| Involuntary | Payment failure, card expiry | Failed charge, dunning |
| Silent | Stops using but does not cancel | Usage decline, no logins |
Churn Rate Calculation
Monthly churn rate = Customers lost / Customers at start of month
Annual churn rate = 1 - (1 - monthly rate)^12
Net revenue retention = (Start MRR + Expansion - Contraction - Churn) / Start MRR
Benchmarks
| Metric | Excellent | Good | Concerning |
|---|
| Monthly churn (SaaS) | <1% | 1-2% | >3% |
| Annual churn (SaaS) | <5% | 5-10% | >15% |
| Net revenue retention | >120% | 100-120% | <100% |
Customer Health Scoring
| Signal | Weight | Healthy | At Risk |
|---|
| Product usage | 25% | Daily/weekly | Monthly or less |
| Feature adoption | 20% | 5+ features | 1-2 features |
| Support sentiment | 15% | Positive/none | Negative |
| Billing health | 15% | On time, expanding | Late, downgrading |
| Engagement | 15% | Opens, clicks | Ignores |
| NPS/CSAT | 10% | Promoter (9-10) | Detractor (0-6) |
Early Warning Signals
| Timeframe | Signal | Action |
|---|
| 7 days | Login frequency drops 50%+ | In-app nudge, value reminder |
| 14 days | Key feature usage stops | CS outreach, usage tips |
| 30 days | No logins for 2+ weeks | Personal CS email, re-engagement |
| 60 days | NPS detractor, unresolved ticket | Executive escalation, save offer |
| 90 days | Cancellation signals | Retention call, custom offer |
Win-Back Campaigns
Timing
| Post-Churn Period | Response Rate | Approach |
|---|
| 0-7 days | 15-25% | Immediate save, address exit reason |
| 7-30 days | 8-15% | New feature announcement, incentive |
| 30-90 days | 3-8% | Major update, significant discount |
| 90+ days | <3% | Annual check-in |
Win-Back Sequence
Email 1 (Day 1): Address exit reason, offer to help
Email 2 (Day 7): New features since they left
Email 3 (Day 14): Comeback incentive (discount or extended trial)
Email 4 (Day 30): Final offer with urgency
Retention Levers
- Onboarding — Time to first value predicts retention more than any other factor
- Engagement loops — Regular touchpoints (weekly reports, digests)
- Feature adoption — Users who adopt 3+ features churn 50% less
- Community — Community members have 2-3x higher retention
- Switching costs — Integrations and data create healthy lock-in
- Proactive support — Reach out before problems become cancellations
CLV Calculation
Simple CLV = ARPU / Monthly Churn Rate
Full CLV = ARPU * Gross Margin % * (1 / Churn Rate)
CLV:CAC ratio target: >3:1
