Ryan Forsythe, Content Marketing Specialist, Moxo

We dive into the ins and outs of calculating customer churn rate, explaining its importance and practical methods to measure it. We’ll also introduce advanced techniques and explain why keeping churn low should be a top priority for any enterprise business.

What is customer churn rate

Customer churn, also known as customer turnover, refers to the number of customers a business loses during a specific time frame. The churn rate measures the percentage of lost customers, helping businesses evaluate their customer retention strategies.

Formula to calculate churn rate

Churn rate (%) = (Customers lost during time period/Customers at start of time period) × 100

The churn rate is essential for strategic decision-making. A high churn rate signals issues with your product/service, customer support, onboarding, or engagement strategies, all of which ultimately affect your revenue and growth.

5 steps to calculate churn rate

Calculating churn rate is essential for understanding customer retention and business health. This metric helps businesses track how many customers they’re losing over a specific period and take corrective actions accordingly.

  1. Define your time period. 

Select a timeframe like monthly, quarterly, or annually, based on your business model and customer interactions.

  1. Determine your initial customer base

Count the total customers at the start of your chosen period as your baseline.

  1. Track customer losses

Monitor how many customers stopped using your service or purchasing during this timeframe.

  1. Apply the churn rate formula

Divide lost customers by the starting total, then multiply by 100. For example, losing 20 out of 500 customers equals a 4% churn rate.

  1. Document and analyze

Record the results, compare with previous periods, and look for patterns to refine retention strategies.

While this calculation gives a good overview, cohort analysis can uncover deeper insights into customer behavior and areas for improvement.

Benefits of knowing your churn rate

  1. Identifying weak points: By analyzing churn rate data, you can pinpoint which products, services, or features cause customer dissatisfaction. Understanding these areas allows you to make targeted improvements to enhance overall client experience and satisfaction.
  1. Revenue forecasting: Calculating churn rate and analyzing the data helps you understand how customer attrition affects future revenue. This enables you to adjust financial strategies and budgets proactively, ensuring sustainable business growth.
  1. Improved customer retention: Insight into customer churn highlights areas where you can address pain points and enhance customer loyalty. Continuous monitoring and adjustment based on churn data help you reduce overall attrition rates effectively.
  2. Prioritizing customer success: Calculating churn and analyzing the data emphasizes the importance of customer success initiatives, such as proactive support and tailored experiences. By focusing on these areas, you can build stronger, long-lasting relationships with your customers.
  3. Competitive advantage: Calculating and understanding your customer/client churn rate gives you insights into market trends and customer behaviors that competitors might overlook. By acting on this knowledge, you can stay ahead of industry changes and maintain a competitive edge.

How to calculate churn with cohort analysis: A step-by-step guide

Accurately calculating churn rate is essential to understand customer loss over time and improve retention. 

You can calculate churn monthly, quarterly, or annually. For monthly calculations, assume no customer churns in their first month, as they pay upfront. Assess at the start of the month and consider only those who have churned, ignoring new sales. In quarterly calculations, be cautious: new sales made in the first month might churn in the second or third month. Including these in your calculations can lead to an overestimation of churn.

Here is a detailed example of how company XYZ calculates its quarterly churn rate.

  1. Define the cohorts 

Start by defining the cohorts. For Company XYZ, cohorts could be customers who signed up in the same quarter.

Company XYZ’s quarterly cohort overview

Month Cohort A Cohort B Cohort C
Month 1 Starts with 1,000, ends with 950 (50 churned) New sales = 100 -
Month 2 900 remain (50 churned) 95 remain (5 churned) New sales = 100
Month 3 850 remain (50 churned) 90 remain (5 churned) 95 remain (5 churned)

  1. Define the time frame

Select a time period—whether monthly, quarterly, or annually—to measure churn. This choice is crucial as it sets the baseline for your analysis and ensures consistent measurements. By standardizing the timeframe, you can reliably calculate and compare churn rates across different periods and identify trends. For XYZ, we will analyze quarterly cohorts.

  1. Identify the initial number of customers

Determine the total number of paying customers at the beginning of your selected time frame. This number serves as the foundation for your churn rate calculation. For instance, if you're calculating for a month, record the customer count on the 1st to maintain accuracy throughout your analysis.

  1. Track lost customers

Monitor how many customers stopped using your service during the specified period. Make sure to exclude any new customers who joined during this time to avoid skewing the results. By identifying the exact number of lost customers, you can better understand areas that need improvement.

  1. Track customer retention

Monitor how many customers from each cohort remain active over subsequent periods. For instance, track how many customers from Q1 are still active in Q2, Q3, etc.

  1. Calculate churn rate

To calculate the churn rate, apply the following formula: 

Churn rate (%) = (Customers lost during time period / Customers at start of time period) * 100

This formula gives you the percentage of customers lost, providing a clear metric to evaluate your retention strategies. Understanding this rate helps in assessing how effectively you're maintaining your customer base.

For each cohort, calculate the churn rate by determining the percentage of customers who stopped using the service in a given period. For example, if 100 customers joined in Q1 and only 80 remained by Q2, the churn rate for Q1 would be 20%.

In summary:

Cohort Start Month Start Customers End Month End Customers Churn Rate
Cohort A Month 1 1,000 Month 3 850 15%
Cohort B Month 2 100 Month 3 90 10%
Cohort C Month 3 100 Month 3 95 5%

Over the quarter, our initial cohort of 1,000 customers dwindled to 850, resulting in a customer churn rate of 15%. During this period, we achieved 300 new sales, but 15 of these also churned. Including those in the churn calculation would adjust the rate to 16.5%.

To address this issue, one straightforward approach is to exclude all new sales from churn rate calculations. By doing so, you focus on Cohort A, the customer base present at the start of the quarter, providing a true churn rate without factoring in new customers.

However, if you wish to include the churn rates of Cohorts B and C, you can opt for a weighted average approach.

Here's how to calculate the Weighted Average Churn Rate for the Quarter:

{(1,000 × 15%) + (100 × 10%) + (100 × 5%)] ÷ Total Customers = 13.75%.

This method ensures that newer customers do not disproportionately affect your churn rate calculations, offering a more balanced view.

  1. Analyze results

Once you've calculated the churn rate, interpret the results by comparing them to your industry’s norms. For example, SaaS businesses often experience monthly churn rates between 3-5%. By benchmarking your rate, you can determine if your retention efforts are competitive or if adjustments are necessary to stay aligned with industry standards.

Calculating churn rate based on averages

For startups experiencing rapid growth or fluctuations in customer numbers, using a simple churn rate formula might not provide the most accurate picture. Instead, calculating the churn rate based on the average customer count offers a clearer insight. Here’s how you can do it:

Formula

To determine the churn rate using averages, follow these steps:

  1. Calculate average customer count

 Average customer count = (Customers at start + Customers at end) ÷ 2

  1. Calculate churn rate

Churn rate (%) = (Customers lost ÷ Average customer count) × 100 

Example

Let’s say your startup began the month with 300 customers and ended with 200 customers. Here's the step-by-step calculation:

  1. Determine the customers lost

Customers lost = 300 (start) - 200 (end) = 100

  1. Calculate the average customer count

 Average customer count = (300 + 200) ÷ 2 = 250

  1. Calculate churn rate:

 Churn rate % = 100 ÷ 250 x 100 = 40%

By using this method, you get a churn rate of 40%, which provides a more nuanced understanding by accounting for variations in the customer base over the period. This approach is particularly valuable in dynamic environments where customer numbers can fluctuate significantly.

Calculating advanced churn rate

To calculate the advanced churn rate, you can utilize a combination of historical data analysis and predictive modeling. Here's how:

  1. Historical data analysis: Start by examining past churn data to understand trends and patterns. Analyze metrics such as the number of customers lost over specific periods and identify common reasons for churn.
  2. Segmentation: Use machine learning to segment your customer base into different groups based on behavior, demographics, or purchase history. This segmentation helps in identifying which groups are more likely to churn.
  3. Predictive modeling: Apply predictive analytics to forecast future churn rates. By incorporating behavioral patterns and machine learning algorithms, you can predict the likelihood of each customer churning and when it might occur.
  4. Continuous monitoring: Regularly update your models with new data to ensure accuracy and refine your predictions over time.

By combining these techniques, you can not only calculate churn rates more precisely but also develop strategies to proactively reduce churn.

What is revenue churn

Revenue churn is a key metric that quantifies the percentage of revenue lost from existing customers over a specific period. It considers factors such as cancellations, downgrades, and service pauses. 

Formula:

Revenue churn rate (%) = (Revenue lost ÷ Revenue at the start of period) × 100

Revenue churn offers deeper insight into customer value loss. Understanding revenue churn is crucial because it provides insights into customer value loss and helps identify areas where customer retention strategies need improvement. By keeping a close eye on revenue churn, businesses can make informed decisions to enhance customer satisfaction and maintain steady revenue growth.

The importance of reducing churn and how to achieve it

A high churn rate impacts revenue, growth, and customer acquisition costs. Here's how to reduce churn effectively:

  1. Optimize onboarding 

Streamline the onboarding process to ensure customers can start using your product with ease. Provide tutorials and resources that highlight key features and demonstrate the value from day one.

  1. Monitor user adoption 

Analyze usage patterns to understand how customers interact with your product. Offer personalized guidance to help users become more proficient and achieve their goals effectively.

  1. Create open feedback channels
