Churn Rate Formula:
Churn Rate = (Customers Lost ÷ Starting Customers) × 100
Retention Rate Formula:
Retention Rate = 100% - Churn Rate

Example: Start with 1000 customers, lose 50 customers

Churn Rate = (50 ÷ 1000) × 100 = 5%

Retention Rate = 100% - 5% = 95%

Frequently Asked Questions (FAQ)

What is churn rate and why is it important?
Churn rate is the percentage of customers who stop using your product or service during a specific period. It's a critical business metric that helps measure customer satisfaction, predict revenue, and guide retention strategies.
How do I calculate churn rate?
Churn Rate = (Customers Lost During Period / Starting Customers) × 100. For example, if you started with 1000 customers and lost 50, your churn rate is 5%.
What's the difference between churn rate and retention rate?
Churn rate measures the percentage of customers lost, while retention rate measures the percentage of customers kept. They are complementary: Retention Rate = 100% - Churn Rate. For a more detailed breakdown of retention, our Customer Retention Rate Calculator lets you analyze retention trends and loyalty metrics in depth.
What is considered a good churn rate?
It varies by industry, but generally: 2% or less is excellent, 2-5% is good, 5-10% is moderate, and above 10% is high. SaaS companies typically aim for monthly churn rates under 5%.
Should I use customers lost or ending customers for calculation?
Both methods give the same result. Use "customers lost" if you know how many left, or "ending customers" if you know your final count. The calculator will compute the other value automatically.

Calculate churn rate regularly based on your business model. Monthly is common for subscription services, quarterly for B2B, and annually for long-term contracts. Consistent measurement helps track trends.
