What is Churn Rate?
Churn rate is the percentage of customers who stop using your product or cancel their subscription over a certain period of time. It’s one of the most important metrics for any business that relies on recurring revenue, like SaaS companies or subscription-based services.
When customers leave, it directly impacts your business growth. That’s why tracking churn regularly can help you catch early signs of customer dissatisfaction or gaps in your service.
How to Calculate Churn Rate
Now you want to know how to calculate churn rate. Luckily, the churn rate is super easy to calculate.
Here’s the formula:
Churn Rate = (Customers Lost During Period / Customers at Start of Period) × 100
Let’s break that down with a quick example. If you started the month with 200 customers and lost 20 by the end, the churn rate would be:
(20 / 200) × 100 = 10%
That means 10% of your customers left during that period.
Why It Matters
Even a small churn rate, say 5%, can seriously affect your Monthly Recurring Revenue (MRR) over time. When you’re losing customers faster than you’re gaining them, your growth slows down, and revenue takes a hit.
That’s why keeping churn low isn’t just good, it’s necessary for sustainable growth.
By tracking churn consistently, you’ll be able to make smarter decisions, improve retention, and strengthen your business foundation.
How to Use This Calculator to Calculate Churn Rate
Using this calculator is super simple and takes less than a minute. You don’t need to sign up, and there’s no complicated setup.
Here’s how this churn rate calculation works, step by step:
- Enter the number of customers at the start of the period: This could be the beginning of the month, quarter, or any time frame you want to measure.
- Enter how many customers you lost during that same period: These are the users who canceled or stopped using your service.
- Click the “Calculate Churn Rate” button: Instantly, the tool will show you your churn rate in percentage form.
That’s it! No formulas, no spreadsheets, just a quick and easy way to check your churn.
Here’s a quick example to give you an idea: If you started the month with 100 customers and lost 33, your churn rate would be 33%.
This tool is perfect for SaaS founders, marketers, and anyone managing a subscription-based business who wants to stay on top of customer retention.
Why Churn Rate Matters for SaaS Businesses
For SaaS companies, churn rate isn’t just another number; it’s a direct signal of how healthy your business is.
When customers leave, it affects your growth and monthly recurring revenue (MRR). You might be gaining new users, but if you’re also losing them at a similar pace, your business isn’t truly growing.
Churn also ties directly into two other key metrics: CAC (Customer Acquisition Cost) and LTV (Customer Lifetime Value).
If it costs you $100 to acquire a new customer, but they churn after a month, you’re not getting much return on that investment. But if your churn rate is low, customers stick around longer, meaning a higher LTV and better ROI on your marketing and sales efforts.
Understanding churn also helps you make smarter business decisions.
It can highlight weak points in your onboarding process, signal where your product experience might be falling short, or show that users need more support and engagement.
In short, the lower your churn rate, the stronger and more sustainable your SaaS business becomes. That’s why tracking and improving churn should be a top priority.
Tips On How to Reduce Churn Rate
Reducing churn isn’t about quick fixes; it’s about creating a better experience for your customers from day one. Here are a few practical ways to get started:
1. Offer real value early through good onboarding
Your onboarding experience sets the tone for the entire customer journey. If users don’t see the value of your product quickly, they’re likely to leave. A smooth, guided onboarding process helps them achieve early wins and builds trust.
2. Listen to user feedback and pain points
Your customers often know exactly what’s missing or frustrating. Collect feedback through surveys, in-app prompts, or even direct conversations. Acting on this feedback shows customers that you care, which can build loyalty.
3. Use churn surveys to find patterns
When customers cancel, ask them why. Churn surveys reveal valuable insights into recurring problems or gaps in your service. Over time, you’ll start spotting trends that you can fix.
4. Improve customer support
Fast and helpful support can turn a frustrated customer into a loyal advocate. Make it easy for users to reach out, and ensure your support team is well-trained to handle issues quickly and professionally.
5. Analyze the behavior of churned users
Look at what churned customers were doing before they left. Tools like heatmaps, session recordings, or Net Promoter Score (NPS) surveys can help you spot patterns, such as where users drop off or get stuck.
By focusing on these areas, you can lower churn, improve retention, and build stronger long-term relationships with your customers.
FAQs Related to Churn Rate & Churn Rate Calculator
What is a good churn rate?
A “good” churn rate can vary depending on your business model, pricing, and audience. But generally, a monthly churn rate of 3–5% or lower is considered healthy for businesses. For enterprise SaaS, even 1–2% is ideal.
How often should I measure churn?
Most SaaS businesses track churn monthly, but depending on your growth stage, you can also measure it quarterly or annually. Monthly tracking gives you more immediate insights to act on.
Does churn include failed payments?
Yes, it often does. Involuntary churn happens when customers leave due to failed payments or billing issues. It’s just as harmful as voluntary churn, so it’s important to monitor and reduce both.
What does 5% churn mean?
It means 5 out of every 100 customers left during a given period. In SaaS, this indicates a regular loss of users that can impact growth if not managed.
How do you calculate churn rate?
Churn rate = (Customers lost during a period ÷ Customers at the start of the period) × 100.
It gives the percentage of customers who left during that time.
What’s the best way to reduce churn?
Focus on delivering real value early, improving customer support, listening to feedback, and keeping users engaged. Tools like NPS surveys, onboarding checklists, and churn analysis reports can also help.
How to calculate MRR (Monthly Recurring Revenue)?
MRR = Number of active customers × Average monthly subscription price
For example, if you have 50 customers paying $20/month, your MRR is 50 × $20 = $1,000.
It helps track predictable, recurring revenue each month.
Why is it called churn rate?
It’s called “churn rate” because it refers to the turnover or “churning out” of customers from your business. Just like milk turns sour or “churns,” this term reflects the idea of customers leaving over time.
