Churn directly impacts a SaaS company's revenue and long-term viability. High churn rates can erode a customer base, diminish recurring revenue, and increase the cost of acquiring new customers to replace those lost. Moreover, in a competitive market, where customer acquisition costs (CAC) are often high, minimizing churn becomes even more crucial to ensure a healthy return on investment (ROI) for marketing and sales efforts.
Churn is typically measured as a percentage and can be calculated on a monthly, quarterly, or annual basis. The most common formula for calculating churn is:
For example, let's say a SaaS company starts the month with 500 customers and loses 20 customers by the end of the month. The monthly churn rate would be:
Churn Rate = (20/500)×100 = 0.04×100 = 4%
This means that 4% of the company's customer base churned during that month.
In the context of SaaS companies, churn isn't just about the number of customers lost—it's also crucial to consider the financial impact of those losses, often referred to as dollar churn or revenue churn. While logo churn focuses on the number of customer accounts that have churned, Revenue churn measures the amount of recurring revenue lost due to those churning customers.
Revenue churn provides a more comprehensive view of a company's financial health, especially when customer accounts vary significantly in value. For instance, losing a few high-value customers can have a much larger impact on revenue than losing a larger number of lower-value customers. By analyzing Revenue churn, companies can better understand the true financial impact of churn and devise more targeted strategies to mitigate these losses. Also, you need to know the difference between gross and net revenue churn as they measure different aspects of your business.
Definition: Gross revenue churn measures the total loss of revenue from existing customers within a given period, without considering any revenue gained from upsells or expansions within the same customer base. The most common way to calculate churn in SaaS is by using Monthly Recurring Revenue (MRR).
Calculation:
Key Points:
Definition: Net revenue churn measures the net loss of revenue from existing customers within a given period, taking into account both the revenue lost from churned customers and the revenue gained from upsells or expansions within the existing customer base.
Calculation:
Where
MRR BoP = Monthly Recurring Revenue at the Beginning of the PeriodKey Points:
Assume a company has the following data for a month:
Gross Revenue Churn:
Gross Revenue Churn = 10,000 / 100,000 = 10%
Net Revenue Churn:
Net Revenue Churn = (10,000 − 5,000) / 100,000 = 5%
In this example, the gross revenue churn is 10%, indicating the total percentage of revenue lost from churned customers. However, the net revenue churn is 5%, which accounts for the revenue recovered through upsells/expansions, giving a more nuanced picture of the company's revenue retention performance.
While monthly churn provides valuable insights into short-term trends, annual churn offers a broader perspective on customer retention over a longer period. To translate monthly churn into annual churn, we can use the following formula:
Continuing with our previous example, where the monthly churn rate was 4%, the annual churn rate would be:
Annual Churn Rate = 1 - (1 - 0.04)^12 = approx. 0.39 or 39 %
This means that if the company maintains a monthly churn rate of 4% consistently throughout the year, it would lose approximately 40% of its customer base annually.
High-Value Customer Loss: Imagine a SaaS company providing services to both small businesses and large enterprises. Losing a single large enterprise client, who contributes significantly more to the MRR than multiple small businesses combined, could drastically affect the company’s revenue. For instance, if one enterprise client contributing $20,000 MRR churns, while 10 small business clients each contributing $500 MRR churn, the financial impact is starkly different—$20,000 lost versus $5,000 lost.
Segmented Customer Analysis: A company might notice that high-value customers in a particular industry are churning at a higher rate. This insight is crucial for tailoring retention strategies. For example, if Revenue churn reveals that tech startups, who typically have a higher MRR, are churning more, the company might develop specific features or support plans to retain these high-value clients.
Both logo churn and Revenue churn are essential for a holistic understanding of churn in a SaaS business:
By monitoring both metrics, SaaS companies can develop a balanced approach to churn management. This dual focus ensures that efforts to improve customer retention are aligned with maintaining and growing revenue, ultimately leading to a more sustainable business model.
Working with and meeting thousands of SaaS companies over the years, we would say that if your churn rate is below 10% you your in a healthy place. However, being very close to or above 10% should raise some red yellow flags and you should look into the root causes of churn (you don't know how? Contact us!). Likewise, if you have a churn rate in the low single digits (0-4%) your prices are probably too low, and you should look into increasing the prices (again - if you don't know how, contact us!).
Minimizing churn requires a proactive approach focused on understanding the underlying reasons why customers leave and implementing strategies to address them. Some common tactics for reducing churn include:
Churn is a critical metric for SaaS companies, serving as a barometer of customer satisfaction and business health. By accurately measuring churn, understanding its implications, and implementing strategies to mitigate it, SaaS companies can foster long-term customer relationships, drive sustainable ARR growth, and ultimately achieve success in a competitive market landscape.
