What is Churn Rate?
Churn rate is the percentage of customers who stop using your product or service during a given time period. It's the opposite of retention—and one of the most critical metrics for subscription and SaaS businesses.
Churn Rate Formula:
Churn Rate = (Customers Lost During Period / Customers at Start of Period) × 100
Example:
- Started month with 100 customers
- Lost 5 customers during the month
- Churn Rate = 5/100 × 100 = 5% monthly churn
- Voluntary churn: Customers cancel intentionally (found alternative, no longer need product)
- Involuntary churn: Customers lost due to failed payments, expired cards, technical issues
Why Churn Rate Matters
The Leaky Bucket Problem
High churn makes growth nearly impossible.
The Math:
- Start with 100 customers
- Acquire 10 new customers each month
- Lose 10 customers each month (10% churn)
- Result: Zero growth despite acquisition efforts
Revenue Impact
Churn directly affects revenue.
Annual Recurring Revenue (ARR) Impact:
- 5% monthly churn = ~46% annual churn
- 10% monthly churn = ~72% annual churn
- Most of your acquired customers are gone within a year
Company Valuation
Investors value companies based on retention.
Valuation Impact:
- Low churn companies trade at 10-15x ARR
- High churn companies trade at 3-5x ARR
- Churn rate is a primary indicator of product-market fit and customer satisfaction
Churn Rate Benchmarks
By Performance Level
| Performance | Annual Churn | Monthly Churn |
|---|---|---|
| **Excellent** | <3% | <0.25% |
| **Good** | 3-7% | 0.25-0.6% |
| **Average** | 7-10% | 0.6-0.8% |
| **Poor** | >10% | >0.8% |
By Company Type
| Company Type | Annual Churn | Notes |
|---|---|---|
| **Enterprise B2B** | 3-5% | Higher ACV, stickier |
| **Mid-Market B2B** | 5-7% | Moderate churn |
| **SMB B2B** | 7-10%+ | Lower ACV, higher churn |
| **B2C Subscription** | 10-15%+ | Lower commitment |
Churn Breakdown
Typical Split:
- Voluntary churn: ~2.6% annually
- Involuntary churn: ~0.9% annually
- Combined average: ~3.5% annually for healthy B2B SaaS
Calculating Churn Rate
Customer Churn vs. Revenue Churn
Two different churn metrics:
Customer Churn Rate:
- Measures percentage of customers lost
- Simple count of canceled accounts
- Useful for understanding customer retention
- Measures percentage of revenue lost
- Accounts for downsells and expansion revenue
- More financially accurate
- Lose 5 customers out of 100 = 5% customer churn
- If those 5 customers were your smallest accounts = 2% revenue churn
- Revenue churn is often lower than customer churn
Monthly vs. Annual Churn
Monthly and annual churn don't convert linearly.
Rough Conversion:
- 1% monthly ≈ 11% annual
- 2% monthly ≈ 22% annual
- 5% monthly ≈ 46% annual
- 10% monthly ≈ 72% annual
Annual Churn % = 1 - (1 - Monthly Ch Rate)^12
Reducing Churn Rate
Identify At-Risk Customers
Spot churn before it happens.
Churn Indicators:
- Declining usage or logins
- Reduced feature adoption
- Support tickets increasing
- Payment failures
- Negative sentiment in communications
- Product analytics (usage patterns)
- Customer health scores
- NPS surveys and feedback
- Support ticket trends
Improve Onboarding
Early experience determines long-term retention.
Onboarding Best Practices:
- Fast time-to-value (TTV)
- Clear success metrics
- Proactive customer success outreach
- Training and resources
- Early check-ins after signup
- Companies with strong onboarding see 30-50% lower churn
- First 90 days are critical—most churn happens early
Focus on Customer Success
Help customers achieve outcomes.
Customer Success Activities:
- Regular business reviews
- Proactive support and check-ins
- Feature adoption guidance
- Value realization tracking
- Expansion and upsell identification
Reduce Involuntary Churn
Fix preventable churn.
Involuntary Churn Solutions:
- Automated dunning for failed payments
- Multiple payment retry attempts
- Up-to-date billing information
- Clear payment reminders
- Easy payment method updates
- Involuntary churn represents 20-30% of total churn
- Mostly preventable with proper payment systems
Common Churn Mistakes
Ignoring Early Warning Signs
Most customers show churn signals before leaving.
Watch For:
- Declining engagement
- Increased support tickets
- Leadership changes at customer company
- Budget cuts or restructuring
- Competitor mentions
Not Measuring Cohort Churn
Aggregate churn hides problems.
Cohort Analysis:
- Track churn by signup month
- Compare different customer segments
- Identify problematic cohorts
- Measure improvement over time
Over-Focusing on Acquisition
You can't acquire your way out of churn problems.
Growth Reality:
- 10% monthly churn = lose most customers within a year
- Even with strong acquisition, high churn kills growth
- Retention is more valuable than acquisition
No Customer Success Investment
Catching churn requires investment.
Customer Success ROI:
- Every CSM typically saves $500K-$1M annually in retained revenue
- CSM costs are 5-10% of retained revenue
- Strong ROI when reducing churn
Key Takeaways
- Churn rate = percentage of customers who stop using your product over time
- Benchmark: <3% annual churn (excellent), 3-7% (good), >10% (poor)
- Two types: voluntary (cancellations) and involuntary (payment failures)
- Customer churn differs from revenue churn (revenue accounts for downsells/expansion)
- Monthly and annual churn don't convert linearly (5% monthly ≈ 46% annual)
- Reduce churn through: onboarding improvement, customer success, at-risk monitoring
- Involuntary churn is 20-30% of total churn and mostly preventable
- Track cohort churn to identify problematic customer segments
- You can't grow sustainably with high churn—fix the leaky bucket first
- Customer success investment pays for itself through retained revenue
