Customer Retention Rate vs. Churn Rate: Key Differences
January 2025
Retention rate and churn rate are two essential metrics for SaaS businesses. Retention rate tracks how many customers stay, while churn rate measures how many leave. Together, they show customer satisfaction and business health.
Key Points:
- Retention Rate: Percentage of customers who remain over a period.
- Formula:
[(End-period customers - New customers) / Starting customers] × 100 - Example: Starting customers = 100, End-period customers = 110, New customers = 20 → Retention = 90%.
- High retention boosts revenue and reduces acquisition costs.
- Formula:
- Churn Rate: Percentage of customers who leave in a period.
- Formula:
(Customers lost / Starting customers) × 100 - Example: Starting customers = 1000, Lost customers = 50 → Churn = 5%.
- High churn signals dissatisfaction and increases costs.
- Formula:
Quick Comparison:
| Aspect | Retention Rate | Churn Rate |
|---|---|---|
| Focus | Tracks loyal customers | Tracks lost customers |
| Calculation | Measures staying users | Measures leaving users |
| Impact | Shows satisfaction | Flags dissatisfaction |
| Business Signal | Stability, growth | Problems, fixes |
Tracking both metrics helps SaaS companies predict revenue, improve customer experience, and grow sustainably. High retention and low churn are the ultimate goals.
Understanding Customer Retention Rate
What Customer Retention Rate Means
Customer retention rate shows the percentage of customers who stick with your SaaS product over a specific period. It’s a key indicator of how well your product meets customer expectations and delivers consistent value.
While retention rate tells you how many customers stay, churn rate reveals how many leave – both are essential for evaluating performance.
How to Calculate Retention Rate
Here’s the formula to calculate customer retention rate:
[(Number of customers at end of period - New customers during period) / Number of customers at start of period] × 100
Here’s a quick example to make it clear:
| Metric | Value |
|---|---|
| Starting customers | 100 |
| New customers gained | 20 |
| End-period customers | 110 |
| Retention rate | 90% |
In this case, 90% of the original customers stayed with the product during the given period.
Why Retention Rate Matters for SaaS Growth
Retention rate plays a huge role in driving SaaS growth for several reasons:
- Boosts Customer Lifetime Value (CLV): Retained customers contribute more recurring revenue over time and often expand their usage. Successful SaaS companies typically see retention rates between 85% and 95% [2].
- Lowers Acquisition Costs: Keeping customers means you spend less on replacing them, which helps stabilize revenue and simplifies growth planning.
- Improves Product Development: Long-term users provide feedback that helps refine features, leading to better satisfaction and retention.
Retention rate gives insight into who stays, while churn rate sheds light on who leaves – together, they provide a full picture of your SaaS performance.
Understanding Churn Rate
What Churn Rate Means
Churn rate measures the percentage of customers who stop using your SaaS product within a specific time frame. Think of it as the "leaky bucket" indicator for your business – it shows how quickly you’re losing customers and pinpoints where the issues might be. A high churn rate often points to problems like poor customer satisfaction, a mismatch between your product and the market, or gaps in customer support.
How to Calculate Churn Rate
Calculating churn rate is simple:
(Number of customers lost during the period / Total number of customers at start of period) × 100
Here’s an example to make it clearer:
| Metric | Value |
|---|---|
| Starting customers | 1000 |
| Customers lost | 50 |
| Time period | 1 month |
| Churn rate | 5% |
For early-stage SaaS companies, churn rates typically fall between 3-7% [6].
Why Churn Rate Matters for SaaS Growth
Churn rate has a direct impact on both growth and revenue for SaaS businesses:
Revenue Loss: Every customer who churns takes their subscription fee with them. For instance, losing a $50/month customer acquired at $100 results in an immediate net loss [1].
Growth Challenges: High churn forces you to spend more on acquiring new customers just to maintain your current numbers, making growth harder to achieve. As Demand Farm explains:
"A high churn rate can lead to you spending more money on acquiring new customers which is not sustainable in the long run" [6].
Increased Acquisition Costs: High churn drives up customer acquisition expenses. For example, with a 10% monthly churn rate and a $100 acquisition cost per customer, replacing 100 lost customers would require $10,000 every month.
Top-performing SaaS companies keep annual churn rates between 5-15% [2]. This allows them to allocate more resources toward growth rather than constantly replacing lost customers.

Comparing Retention Rate and Churn Rate
For SaaS businesses, understanding retention rate and churn rate is key to shaping effective customer success strategies. While they might seem like two sides of the same coin, each provides unique insights into customer behavior and overall business health.
Retention Rate vs. Churn Rate: Key Differences
Here’s a quick breakdown of how these metrics compare:
| Aspect | Retention Rate | Churn Rate |
|---|---|---|
| Focus | Tracks customer loyalty | Tracks customer loss |
| Calculation | Measures retained customers | Measures lost customers |

How Retention and Churn Work Together
Retention and churn rates complement each other, offering a full picture of your business performance. Retention highlights loyalty and satisfaction, while churn identifies where things may be going wrong. Together, they act as diagnostic tools for identifying trends and addressing challenges in your customer base.
Spotting Patterns
Analyzing these metrics side by side can uncover trends that might go unnoticed if viewed in isolation. For example, a drop in retention paired with rising churn clearly signals dissatisfaction that needs immediate attention [1][4].
Driving Strategic Changes
These insights are vital for decision-making. Consider a SaaS company that noticed high churn due to poor onboarding. By revamping their onboarding process, they boosted retention by 15% and cut churn by 10% [3][5].
Actionable Insights
Regularly tracking these metrics helps you spot correlations and trends. Use this data to refine your product and improve the customer experience, focusing on strategies that both strengthen retention and lower churn.
Practical Tips for SaaS Businesses
Why Tracking Both Metrics is Important
Monitoring both retention and churn rates gives you a clear picture of customer behavior, helping you make informed decisions to boost satisfaction and growth. Tools like modern CRM systems and analytics platforms can detect patterns early, allowing you to address potential issues before they escalate. Many established SaaS companies aim for a 90% retention rate as their standard [2].
Ways to Improve Retention and Lower Churn
The median net retention rate for SaaS businesses (which includes retained customers and upsells) is 102%, while the median gross retention rate is 91% [4]. To hit or surpass these numbers, focus on the following strategies:
Create a Smooth Onboarding Process
Help customers find value quickly with a clear and efficient onboarding experience, setting the stage for long-term success.
Provide Proactive Support
- Regularly check in with customers
- Monitor usage patterns for any red flags
- Offer multiple support options, like live chat, email, or phone
- Include self-service tools, such as knowledge bases or FAQs
Leverage Data Analytics
Keep an eye on key metrics to identify and address risks early. Pay close attention to engagement levels and usage trends to prevent churn.
"A high retention rate establishes confidence that your business can generate sustainable income. When retention trumps churn, it indicates that everything you’ve done to keep your customers satisfied is working and they are willing to keep buying it from you." – Shopify Blog [2]
Using SaaS Playbooks for Better Results
SaaS Playbooks provide actionable resources to help businesses enhance retention and reduce churn. These playbooks include templates and strategies for marketing, sales, and customer success, making it easier to implement effective plans.
Conclusion
Retention rates reflect customer satisfaction and business stability, while churn pinpoints areas that need attention. Together, these metrics offer a clear picture of a company’s overall health.
For newer businesses, a churn rate between 3-7% is often acceptable, but this should decline as the company grows and matures [6]. As mentioned earlier, prioritizing customer success and refining your product can have a major impact on these numbers.
Here are some practical steps to improve retention and reduce churn:
- Keep a close eye on metrics to identify trends and make informed decisions.
- Address potential issues early with proactive customer success efforts.
