Churn rate explained: definition, examples & how to use it

The percentage of customers who stop using a product or cancel their subscription during a given time period.

Churn rate

Churn rate (also called attrition rate) measures the percentage of customers who stop using your product or cancel their subscription during a given time period. It's one of the most critical metrics for subscription-based businesses because it directly impacts growth, revenue, and company valuation. Even small improvements in churn can dramatically improve business outcomes.

Why it matters

Churn rate is a fundamental business health metric:

  • Impacts growth: High churn means you're constantly replacing lost customers instead of growing
  • Affects unit economics: Lower churn means higher customer lifetime value (LTV)
  • Indicates product health: Churn is a lagging indicator of product and service quality
  • Determines sustainability: Businesses with high churn require constant acquisition spending
  • Influences valuation: Investors heavily weight churn in company valuations

    • Calculating churn rate

    Basic formula

    \\\`

    Churn Rate = (Customers Lost During Period / Customers at Start of Period) × 100

    \\\`

    Example:

  • 1,000 customers at the start of the month
  • 50 customers cancelled during the month
  • Churn Rate = 50 / 1,000 × 100 = 5%

    • Revenue churn

    For subscription businesses, revenue churn may differ from customer churn:

    \\\`

    Revenue Churn = (MRR Lost / Starting MRR) × 100

    \\\`

    Revenue churn accounts for:

  • Cancellations
  • Downgrades
  • Doesn't include upgrades (that's expansion)

    • Net revenue churn

    Accounts for expansion revenue:

    \\\`

    Net Revenue Churn = (MRR Lost - Expansion MRR) / Starting MRR × 100

    \\\`

    Negative net revenue churn means expansion exceeds losses-a sign of a very healthy business.

    Churn rate benchmarks

    Benchmarks vary significantly by business type:

    B2b saas

  • Excellent: < 3% annual (< 0.25% monthly)
  • Good: 5-7% annual
  • Average: 5-10% annual
  • Concerning: > 10% annual

    • Consumer subscriptions

  • Excellent: < 5% monthly
  • Average: 5-10% monthly
  • High: > 10% monthly

    • Enterprise software

  • Excellent: < 5% annual
  • Good: 5-10% annual
  • Concerning: > 10% annual

    • Note: SMB customers typically churn at 2-3x the rate of enterprise customers.

    Types of churn

    Voluntary churn

    Customer actively decides to leave:

  • Found a better alternative
  • No longer need the product
  • Dissatisfied with product or service
  • Budget cuts
  • Company went out of business

    • Involuntary churn

    Customer leaves unintentionally:

  • Credit card expired
  • Payment failed
  • Technical issues prevented renewal

    • Involuntary churn is often 20-40% of total churn and can be reduced with better payment recovery.

    Early churn

    Customers who leave soon after signing up:

  • Never reached activation
  • Didn't experience value
  • Onboarding friction

    • Late churn

    Long-term customers who eventually leave:

  • Needs changed over time
  • Competitor improved
  • Internal champion left

    • Analyzing churn

    Cohort analysis

    Track churn by signup cohort to identify:

  • Seasonal patterns
  • Impact of product changes
  • Quality of acquisition sources

    • Segment analysis

    Compare churn across segments:

  • By plan/pricing tier
  • By acquisition channel
  • By customer size
  • By use case

    • Churn surveys

    Ask departing customers why they left:

  • Exit surveys
  • Cancellation interviews
  • Win/loss analysis

    • Predictive indicators

    Identify signals that predict churn:

  • Decreased login frequency
  • Support tickets
  • Feature usage decline
  • NPS scores

    • Reducing churn

    Improve onboarding

    Many customers churn because they never experienced value:

  • Accelerate time to first value
  • Provide clear guidance
  • Remove friction
  • Offer help early

    • Increase engagement

    Engaged customers churn less:

  • Email campaigns
  • In-app messages
  • Feature education
  • Success stories

    • Build habits

    Products that become habits are sticky:

  • Regular use cases
  • Integrations with workflows
  • Team adoption

    • Deliver continuous value

    Don't stop selling after the sale:

  • Regular check-ins
  • Proactive success management
  • Continuous education
  • New feature announcements

    • Identify at-risk customers

    Intervene before they leave:

  • Monitor health scores
  • Set up alerts for declining engagement
  • Proactive outreach
  • Save offers for at-risk accounts

    • Reduce involuntary churn

    Don't lose customers to failed payments:

  • Smart retry logic
  • Multiple payment methods
  • Pre-expiration notifications
  • Grace periods

    • Act on feedback

    Show customers you listen:

  • Respond to support tickets quickly
  • Implement requested features
  • Close the loop when shipping requests

    • Churn and growth

    The relationship between churn and growth is crucial:

    The leaky bucket

    \\\`

    Net Growth = New Customers - Churned Customers

    \\\`

    If churn equals acquisition, you're not growing.

    The power of small improvements

    A 5% reduction in churn can increase profits by 25-95% (Bain & Company).

    Churn compounds

    Monthly churn rates compound over a year:

  • 3% monthly ≈ 30% annual
  • 5% monthly ≈ 46% annual
  • 10% monthly ≈ 72% annual

    • Common churn mistakes

    Ignoring early signals

    By the time customers cancel, it's often too late. Monitor leading indicators.

    Treating all churn the same

    Voluntary vs. involuntary, early vs. late churn have different causes and solutions.

    Focusing only on saves

    Save offers can reduce churn temporarily but don't fix underlying problems.

    Not learning from churned customers

    Every churned customer is a learning opportunity. Understand why.

    Acquisition over retention

    Acquiring customers you can't retain is expensive and unsustainable.
