You're acquiring 100 customers but losing 20. That's 20% churn. Reducing churn by 5% can increase profits by 25-95%. Here's how to analyze and fix it.

The Economics of Churn

Churn is expensive:

The Cost

Lost revenue (customers who left)
Lost future revenue (LTV not realized)
Acquisition cost wasted (CAC spent for nothing)
Negative word of mouth (churned customers tell others)

The Math:

If you lose 20 customers/month at $500/month each = $10,000/month lost revenue = $120,000/year. Plus you spent $20,000 to acquire them (at $1,000 CAC). Total cost: $140,000/year.

Identifying Churn Indicators

Churn is predictable. Watch for these signals:

Usage Indicators

Decreased login frequency
Reduced feature usage
No engagement in 30+ days

Support Indicators

Multiple support tickets
Unresolved issues
Low satisfaction scores

Payment Indicators

Failed payment attempts
Payment method expired
Downgrade requests

Voluntary vs. Involuntary Churn

Different types need different solutions:

Voluntary Churn (They Cancel)

Product didn't meet expectations
Found better alternative
No longer need solution
Fix: Improve product, onboarding, value delivery

Involuntary Churn (Payment Failed)

Expired credit card
Insufficient funds
Bank declined
Fix: Payment retry logic, dunning emails

Strategies to Reduce Churn (Onboarding, Success)

Prevent churn before it happens:

1. Better Onboarding

Get them to "aha moment" faster
Show value immediately
Set up success metrics
Proactive check-ins

2. Customer Success

Regular health checks
Proactive support
Success resources
Expansion opportunities

Calculating the Revenue Impact of 1% Improvement

Small improvements compound:

The Math

If you have 1,000 customers at $100/month:

Current churn: 5% = 50 customers/month = $5,000/month lost
Improve to 4% churn = 40 customers/month = $4,000/month lost
Savings: $1,000/month = $12,000/year
Plus: 10 more customers retained = $12,000/year revenue
Total impact: $24,000/year from 1% improvement

Conclusion

Churn is expensive. Analyze churn indicators, distinguish voluntary from involuntary, implement retention strategies (onboarding, success), and measure the impact. A 1% improvement can mean tens of thousands in additional revenue. Retention is 5-25x cheaper than acquisition.
