What Is Customer Churn?

Customer churn, also known as customer attrition, is the percentage of customers who discontinue their relationship with a business over a defined period. This can include canceling a subscription, not renewing a contract, or switching to a competitor. Churn is a key metric because it reflects a company’s ability to retain customers, which is often more cost-effective than acquiring new ones. High churn rates can hinder sustainable growth by eroding recurring revenue, a challenge for industries like SaaS and financial services, as highlighted in IBM.

There are two primary types of churn: voluntary and involuntary. Voluntary churn occurs when customers choose to leave, often due to dissatisfaction or better options elsewhere. Involuntary churn happens without the customer’s intent, such as through payment failures or technical issues. Understanding churn is crucial for improving customer retention, as it helps businesses pinpoint pain points and develop strategies to keep customers engaged, a priority in competitive sectors like financial services, as discussed in our financial services customer experience insights.

How to Calculate Customer Churn Rate

Calculating the churn rate helps businesses quantify customer attrition and evaluate their retention efforts. The standard formula for customer churn rate is:

Churn Rate = (Customers Lost ÷ Total Customers at Start) × 100

Step-by-Step Examples

Here’s an example for a subscription business in 2025:

• Step 1: At the beginning of January, the business has 1,000 customers.

• Step 2: By the end of January, 50 customers have canceled their subscriptions.

• Step 3: Apply the formula: Churn Rate = (50 ÷ 1,000) × 100 = 5%.

This indicates a monthly churn rate of 5%. If this rate persists, the annual churn rate would be 5% × 12 = 60%, which is high for most industries, as we’ll explore later. Let’s consider another scenario: a SaaS company starts with 500 customers and loses 30 in a month.

Using the formula: Churn Rate = (30 ÷ 500) × 100 = 6%. This higher rate might signal issues like poor onboarding or lack of product value, requiring immediate action to improve retention.

Gross vs. Net Churn

Gross churn measures the revenue lost from customers who leave, expressed as a percentage of total revenue. For example, if a SaaS company loses $10,000 in monthly recurring revenue (MRR) from a total of $200,000, the gross churn rate is (10,000 ÷ 200,000) × 100 = 5%. Net churn factors in revenue gained from existing customers through upsells or expansions. If the same company gains $5,000 in expansion revenue, the net churn rate becomes [(10,000 – 5,000) ÷ 200,000] × 100 = 2.5%, according to Paddle. These metrics are essential for SaaS businesses, as explored in our CX technologies page, which discusses tech solutions for retention.

Types of Customer Churn

Customer churn can be divided into two main categories: voluntary and involuntary, each with unique causes and solutions. Further subcategories help businesses understand churn in different contexts.

• Voluntary Churn: This happens when customers actively decide to stop using a service, often due to dissatisfaction, unmet expectations, or better alternatives. For instance, a customer might cancel a streaming service because a competitor offers more content, as noted in Paddle. Voluntary churn can often be mitigated with improved customer experiences.

• Involuntary Churn: This occurs without the customer’s intent, typically due to external issues like payment failures or expired credit cards. For example, a subscription might lapse if a customer’s payment method fails repeatedly. Involuntary churn can account for 20–40% of total churn, depending on the industry, and requires operational solutions like payment retries.

  
  

Subcategories of Churn

Churn can also be classified as contractual or non-contractual. Contractual churn applies to businesses with fixed-term agreements, like SaaS subscriptions, where customers must actively cancel. Non-contractual churn occurs in businesses without formal contracts, such as retail, where customers simply stop buying. For example, a grocery delivery service might see non-contractual churn if a customer switches to a local store, a trend common in subscription-based businesses, as discussed in our guide on keeping subscription customers engaged.

Common Causes of Customer Churn

Identifying the causes of customer churn is essential for creating effective retention strategies. Here are the top reasons customers leave in 2025, across industries like SaaS, financial services, and subscription services.

• Poor Customer Service Experiences: Negative support interactions can push customers away. A 2024 study found that 67% of customers left a business due to poor service, often citing long wait times or unresolved issues as the cause.

• Lack of Product-Market Fit or Unmet Expectations: When a product fails to meet customer needs, churn is likely. In SaaS, this might occur if a tool lacks promised features, contributing to 40% of churn in B2B companies due to poor fit.

• Competitive Pricing and Better Alternatives: Customers may switch to competitors offering better pricing or features. In financial services, this drives a 19% annual churn rate, as customers seek banks with lower fees or better digital experiences.

• Ineffective Onboarding Processes: A complex or unclear onboarding process can lead to early churn. In subscription services, poor onboarding increases churn by 30% in the first 90 days, as customers struggle to see value.

• Billing Issues and Payment Failures: Involuntary churn often results from billing problems, such as declined payments or unclear invoices. This accounts for 25% of churn in subscription models, underscoring the need for streamlined billing processes.

Addressing these issues can significantly lower churn rates, particularly in industries like ecommerce, as explored in our ecommerce customer experience guide.

Industry Benchmarks: Average Churn Rates

Churn rates differ across industries, influenced by factors like business models, customer expectations, and competition. Here are average churn rates for key industries in 2025, based on recent data.

• SaaS: Annual churn rates for SaaS companies typically range from 10–14%, with smaller companies often seeing higher rates due to limited retention resources.

• Financial Services: This sector experiences a higher churn rate of 19% annually, driven by competition and the demand for seamless digital experiences, such as mobile banking apps.

• Digital Media & Entertainment: Streaming services and online media platforms have a lower churn rate of 5.23%, benefiting from strong content and subscription models that encourage long-term engagement.

• Subscription Services: Businesses like meal kits or fitness apps see an annual churn rate of 5–7%, supported by recurring billing but challenged by customer fatigue over time.

Factors Influencing Churn Rates

Factors like customer lifecycle stage, market competition, and economic conditions affect these rates. For instance, SaaS companies with effective onboarding can reduce churn by 15%, while financial services may see higher churn during economic downturns due to customers switching to more affordable options. Additionally, subscription services often face higher churn during the first few months if customers don’t perceive ongoing value, a trend that can be mitigated with consistent engagement strategies. These benchmarks help businesses set realistic goals, especially in sectors like digital media, as discussed in our guide on keeping subscription customers engaged.

Strategies to Reduce Customer Churn

Reducing customer churn requires proactive strategies that tackle the root causes of attrition. Below are six effective strategies for 2025 to improve retention in industries like SaaS, financial services, and subscription services.

Enhance Customer Onboarding Experiences

A smooth onboarding process helps customers see value quickly, reducing early churn. For example, a SaaS company using interactive tutorials can cut churn by 20% in the first 90 days. Clear communication, step-by-step guidance, and immediate support during onboarding are crucial, especially in complex industries like financial services, as noted in our financial services customer experience insights.

Implement Proactive Customer Support

Proactive support, such as addressing issues before they escalate, can prevent churn. A subscription service might notify customers of a failed payment and offer alternatives, reducing involuntary churn by 15%. Tools like live chat, AI chatbots, and automated alerts can improve responsiveness, ensuring customers feel supported throughout their journey.

Utilize Customer Feedback for Continuous Improvement

Collecting and acting on feedback helps identify pain points. Surveys, NPS scores, and reviews can reveal why customers leave, enabling improvements. Companies that act on feedback reduce churn by 10%, a strategy effective in digital media, per our guide on keeping subscription customers engaged. Regularly analyzing feedback ensures businesses stay aligned with customer needs.

Offer Loyalty Programs and Incentives

Loyalty programs reward long-term customers, encouraging them to stay. An ecommerce business offering discounts or free shipping after a year can lower churn by 12%. Incentives like exclusive content or early access to new features are particularly effective in subscription services, where consistent engagement is key.

Monitor Customer Engagement and Usage Patterns

Tracking engagement metrics, such as login frequency or feature usage, can identify at-risk customers. A SaaS company might notice a user hasn’t logged in for 30 days and send a re-engagement email with a tutorial or discount, reducing churn by 8%. Regular monitoring helps address disengagement early, ensuring customers remain active.

Employ Predictive Analytics to Identify At-Risk Customers

Predictive analytics uses data to forecast which customers are likely to churn, enabling timely interventions. A financial services company might identify a customer with declining transactions and offer personalized support, cutting churn by 18%. This approach leverages historical data and machine learning to prioritize high-risk customers, making it a powerful tool in 2025.

These strategies can significantly reduce churn and foster lasting customer relationships, especially in omnichannel environments, as discussed in our omnichannel customer service guide.

Predicting and Preventing Churn with AI

In 2025, AI and machine learning are revolutionizing how businesses predict and prevent customer churn. By analyzing large datasets, AI can identify patterns and forecast which customers are at risk, enabling proactive measures to retain them.

How AI Forecasts Churn

AI models analyze historical data—such as usage patterns, support interactions, and billing history—to predict churn. For example, a machine learning algorithm might flag a customer who hasn’t engaged with a SaaS platform in 30 days as high-risk. These models can achieve prediction accuracy rates of up to 85%, allowing businesses to intervene before a customer leaves. This predictive capability is especially valuable in industries with high competition, where early action can make a significant difference.

Tools and Models for Churn Prediction

Tools like Gainsight and Salesforce integrate AI-driven churn prediction into CRM systems. These platforms use models like logistic regression, decision trees, or neural networks to assign churn risk scores, helping teams prioritize outreach. A subscription service might use Gainsight to identify at-risk customers and reduce churn by 20% through targeted campaigns. Other tools, such as HubSpot and ChurnZero, also offer robust analytics for smaller businesses, making AI accessible across company sizes.

Benefits of Early Intervention

Early interventions, such as personalized offers or support outreach, can significantly lower churn rates. A financial services company might use AI to detect declining engagement and offer a tailored discount, cutting churn by 15%. AI-driven prevention not only retains customers but also boosts loyalty, a key focus for industries like ecommerce, as noted in our ecommerce customer experience guide.
