# Churn Prediction & Prevention

Identify customers at risk of churning and deploy automated retention interventions to save revenue.

## Workflow

1. Define churn: cancellation, non-renewal, usage drop below threshold, payment failure after grace period.
2. Collect historical churn data: past 12–24 months of cancellations, reasons, customer attributes.
3. Identify churn indicators: usage decline, support ticket increase, payment issues, engagement drop.
4. Build churn risk model: score customers 0–100 based on behavioral and demographic signals.
5. Segment at-risk customers: imminent churn (score 80–100), at risk (60–79), watch (40–59), healthy (<40).
6. Deploy automated interventions: tailored retention campaigns by risk level and churn reason.
7. Implement manual outreach: high-value customers receive personal contact from CSM team.
8. Track intervention effectiveness: save rate, reason for success/failure, revenue preserved.
9. Refine prediction model: incorporate new data, adjust weights, improve accuracy monthly.
10. Report: churn rate, save rate, revenue at risk, revenue preserved, CAC payback extension.

CHURN DEFINITION AND MEASUREMENT
==================================

CHURN TYPES:

  REVENUE CHURN (most important):
    → Formula: (Revenue Lost from Cancellations / Total Beginning Revenue) × 100
    → Gross Revenue Churn: Cancellations only (before expansion revenue)
    → Net Revenue Churn: Cancellations minus expansion (upsell, cross-sell, price increases)
    → Target: < 5% monthly (SaaS), < 2% monthly (enterprise SaaS)
    → Negative net churn (< 0%) = expansion revenue > cancellation revenue (elite tier)

  CUSTOMER CHURN:
    → Formula: (Customers Lost / Total Customers at Period Start) × 100
    → Monthly customer churn target: < 3% (SaaS), < 1% (enterprise)
    → Annual customer churn target: < 25% (SaaS), < 10% (enterprise)

  LOG CHURN (usage-based):
    → Definition: Customer still subscribed but usage dropped below functional threshold
    → Indicator: Login frequency down 50%+ over 30 days, feature adoption stalled
    → Warning: Log churn precedes revenue churn by 30–90 days on average
    → Action: Proactive intervention before formal cancellation

  LIFESPAN EXTENSION IMPACT:
    → Reducing monthly churn from 5% to 4% increases average customer lifespan by 50%
    → At $1,000 MRR per customer and $200 CAC:
       * 5% monthly churn → avg. lifespan 20 months → LTV $20,000
       * 4% monthly churn → avg. lifespan 25 months → LTV $25,000
       * 1% reduction = $5,000 more LTV per customer (2.5x CAC recovered)

    → Script: "I understand pricing is a concern. Let me show you the
       ROI you're getting, and we can explore options that work for your budget."
    → Success rate: 30–50% (hardest to retain)

  FEATURE-DRIVEN CHURN (missing capabilities):
    → Interventions: Workaround demonstration, roadmap preview, alternative features
    → Script: "I hear you — [feature] is important. Here's how you can
       accomplish the same result with [existing feature], and here's

## Edge Cases

- **Enterprise annual contracts**: Traditional churn signals don't apply when customers are locked in for 12–24 months. Solution: Focus on renewal risk prediction (6 months before renewal), expansion signals (up-sell/cross-sell opportunity), and "quiet churn" (contracted but minimal usage). Engage renewal conversation 90–180 days before expiration.
- **Self-service / PLG churn**: No CSM to intervene — automation must handle everything. Solution: In-app messaging for at-risk users, automated email sequences triggered by usage drop, self-serve help center with contextual content, chatbot for immediate support. Free users: focus on activation (feature adoption), not retention.
- **High-churn products (< 3-month average lifespan)**: Traditional churn models don't work when baseline churn is 30%+. Solution: Focus on reducing time-to-value (TTV). If customers get value in day 1, churn drops significantly. A/B test onboarding flows, implement "aha moment" tracking, optimize pricing for value perception.
- **Churn reason data accuracy**: Customers rarely give honest churn reasons (they say "too expensive" even when it's product issues). Solution: Analyze behavioral data (what did they do before churning?), track support ticket themes, monitor usage patterns, conduct exit interviews with a sample. Cross-reference stated vs. actual churn reasons quarterly.
- **Ethical retention practices**: Don't use dark patterns to prevent cancellation (hidden unsubscribe, guilt-tripping language, making cancellation difficult). This destroys brand reputation and increases complaints. Best practice: Make cancellation easy, understand the reason, offer genuine alternatives, exit gracefully. Some churn is healthy — it frees resources for better-fit customers.
