What is Churn Rate?

Churn rate measures the percentage of customers who stop using your product or service during a specific period. It's a critical metric for subscription businesses, SaaS companies, and any business with recurring revenue, indicating customer satisfaction and business health.

This calculator helps with:

  • Customer retention - Measure how well you retain customers over time
  • Business health - Assess sustainability and growth potential
  • Revenue forecasting - Predict future revenue based on retention
  • Customer lifetime - Calculate average customer lifespan
  • Growth planning - Determine acquisition needs to offset churn

For comprehensive customer analysis, use our customer lifetime value calculator to understand customer worth.

How Churn Rate Calculator Works

The calculation uses these formulas:

Churn Rate = (Customers Lost / Starting Customers) × 100
Retention Rate = 100 - Churn Rate

Additional calculations:

  • Ending Customers = Starting - Lost + New
  • Annual Churn = Period churn extrapolated to year
  • Customer Lifetime = 1 / Churn Rate (in periods)
  • Health Status = Based on industry benchmarks

Key Concepts Explained

Churn Rate

Percentage of customers lost. Lower is better. 5% monthly churn means losing 60% of customers annually if not replaced.

Retention Rate

Percentage of customers retained. Inverse of churn. 95% retention means 5% churn. Higher retention drives profitability.

Customer Lifetime

Average time customer stays. Calculated as 1/churn rate. 5% monthly churn = 20 month average lifetime.

Revenue Churn

Percentage of recurring revenue lost. Can differ from customer churn if high-value customers leave or expand.

Factors That Affect Your Results

1. Product-Market Fit

Strong fit reduces churn significantly. If churn is high, evaluate whether product truly solves customer problems and delivers promised value consistently.

2. Customer Onboarding

Effective onboarding reduces early churn by 50%+. First 30-90 days are critical. Ensure customers achieve quick wins and understand product value.

3. Customer Support

Responsive, helpful support significantly impacts retention. Customers with positive support experiences are 3-5x more likely to renew and recommend.

4. Pricing Strategy

Pricing misalignment causes churn. Too high deters renewals; too low attracts wrong customers. Ensure pricing reflects value delivered to target segments.

Q: What is a good churn rate?

A: Good churn rates vary by industry. SaaS: 5-7% annually (0.5% monthly), e-commerce: 20-30% annually, subscription services: 5-10% annually. Rates below industry average indicate strong customer retention. Enterprise SaaS often achieves <5% annual churn.

Q: How do I calculate churn rate?

A: Calculate using: (Customers Lost / Starting Customers) × 100. For example, losing 50 of 1,000 customers equals 5% churn rate. Calculate monthly or annually depending on business model. Track consistently for accurate trends.

Q: What's the difference between customer churn and revenue churn?

A: Customer churn measures percentage of customers lost. Revenue churn measures percentage of recurring revenue lost. Revenue churn can be negative if expansion revenue from existing customers exceeds lost revenue. Both metrics are important for business health.

Q: How can I reduce churn rate?

A: Reduce churn by: improving onboarding, providing excellent customer support, regularly engaging customers, addressing pain points proactively, offering incentives for renewals, gathering and acting on feedback, and identifying at-risk customers early for intervention.

Q: What causes high churn rates?

A: High churn results from: poor product-market fit, inadequate onboarding, lack of customer support, pricing issues, better competitive alternatives, product quality problems, or failing to deliver promised value. Analyze churn reasons to identify root causes.

Q: How does churn rate affect business growth?
