How To Calculate Churn Rate

How to calculate churn rate

Understanding and managing customer churn is crucial for sustained success. Customer churn rate, often simply referred to as churn rate, is a key metric that businesses use to measure the percentage of customers who stop using their products or services during a given period.

Calculating churn rate empowers companies to assess customer retention efforts, identify potential issues, and implement strategies to enhance customer satisfaction.

In this comprehensive guide, we delve into what customer churn rate is, the formula to calculate it, the steps involved, and how to interpret the results.

What is Customer Churn Rate?

Customer churn rate is a metric that measures the percentage of customers who cease their relationship with a business within a specific timeframe. It is a critical indicator of customer satisfaction, loyalty, and the overall health of a business.

A high churn rate implies that a significant number of customers are leaving, which can impact revenue and long-term success.

Churn Rate Formula

The formula to calculate churn rate is relatively straightforward:

Churn Rate= Customers Lost during a Period /(Total Customers at the Start of the Period​)×100

This formula provides a percentage, which represents the proportion of customers lost during the specified time frame.

Steps to Calculate Churn Rate

Calculating churn rate involves a few simple steps:

  1. Determine the Time Period: Identify the specific time frame for which you want to calculate the churn rate. It could be monthly, quarterly, or annually, depending on the nature of your business and industry standards.
  2. Count Customers Lost: Determine the number of customers who discontinued their relationship with your business during the chosen time period.
  3. Find the Total Customers at the Start: Establish the total number of customers at the beginning of the selected time frame.
  4. Apply the Formula: Plug the values into the churn rate formula and calculate the percentage.

What to Do After Calculating Churn Rate

After calculating the churn rate, businesses need to interpret the results and take appropriate actions. Here are some key steps to follow:

  1. Analyze the Results: Assess the calculated churn rate in the context of industry benchmarks and your business goals. A high churn rate may indicate issues with customer satisfaction or service quality.
  2. Identify Causes: Investigate the reasons behind customer attrition. Conduct surveys, gather feedback, and analyze customer interactions to pinpoint the factors contributing to churn.
  3. Implement Retention Strategies: Develop and implement targeted strategies to reduce churn. This may include improving customer support, enhancing product features, or offering loyalty programs.
  4. Monitor Changes: Continuously monitor the impact of retention strategies on the churn rate. Regularly reassess and adjust approaches based on customer feedback and market dynamics.

Churn Rate Example

To better understand churn rate calculation, let’s consider an example:

Suppose you started the quarter with 1,000 customers, and during that quarter, 50 customers decided to discontinue their subscription. Applying the churn rate formula, the churn rate for that quarter is 5%.

What is a Good Churn Rate?

The definition of a “good” churn rate varies across industries. Generally, a lower churn rate is desirable, indicating higher customer retention and satisfaction. However, what is considered acceptable can depend on the type of business and market conditions.

For subscription-based services like software as a service (SaaS), a churn rate below 5% per month is often considered acceptable. In more competitive and dynamic industries, a higher churn rate might be expected.

What is Revenue Churn Rate?

While customer churn rate focuses on the number of customers lost, revenue churn rate hones in on the financial impact of customer attrition. Revenue churn rate calculates the percentage of revenue lost due to customers leaving during a specific time frame.

Revenue Churn Rate: ((Lost Revenue from Churned Customers) / Total Revenue at the Beginning of the period) x 100

Revenue churn rate provides a more nuanced perspective, especially in scenarios where customers have different subscription levels or spending patterns.

Customer Churn Rate vs. Revenue Churn Rate

While both customer churn rate and revenue churn rate are vital metrics, they measure different aspects of customer attrition. Customer churn rate focuses on the quantity of customers lost, whereas revenue churn rate considers the financial impact of losing those customers.

For instance, a business might experience a high customer churn rate but a lower revenue churn rate if the departing customers were on lower-value plans. Conversely, a low customer churn rate might mask a significant revenue churn rate if high-value customers are leaving.

How to Track Churn Rate?

Effectively tracking churn rate involves consistent monitoring and leveraging relevant tools and analytics. Here are some strategies for tracking churn rate:

  1. Use Customer Relationship Management (CRM) Software: Implement CRM software to track customer interactions, gather feedback, and identify potential churn indicators.
  2. Utilize Analytics Platforms: Leverage analytics platforms to monitor customer behavior, identify patterns, and predict potential churn risks.
  3. Regularly Update Metrics: Keep churn rate metrics up-to-date and review them regularly. This ensures timely identification of trends and facilitates proactive decision-making.
  4. Implement Customer Feedback Systems: Establish systems for collecting and analyzing customer feedback. This can provide valuable insights into areas that may be contributing to churn.


Calculating and understanding customer churn rate is a fundamental aspect of strategic business management. By consistently monitoring and interpreting churn rate metrics, businesses can implement effective retention strategies, enhance customer satisfaction, and ultimately foster long-term success.

Remember: the key to success lies not just in calculating churn rate, but in using the insights gained to drive positive change and build lasting customer relationships.
