What Is a Churn Rate Calculator?
A Churn Rate Calculator measures the percentage of customers who stop using a product, cancel a subscription or leave a business during a specific period. It helps companies understand how effectively they retain their customers.
Churn is especially important for subscription businesses, SaaS companies, membership platforms, telecom providers and other businesses that depend on recurring customer relationships.
Retention Rate
Shows the percentage of starting customers who remained with your business.
Revenue Churn
Measures recurring revenue lost through cancellations, downgrades or failed renewals.

Customer Churn Rate Formula
When new customers are added during the reporting period, they should not be treated as retained starting customers. This calculator uses the following method:
Customer Churn Formula
Customers Lost = Starting Customers + New Customers − Ending Customers
Churn Rate = (Customers Lost ÷ Starting Customers) × 100
Example Calculation
Suppose a subscription business begins the month with 1,000 customers, adds 50 new customers and finishes with 970 customers.
Customers lost would equal 1,000 + 50 − 970, which gives 80 lost customers. The monthly churn rate would therefore be 80 divided by 1,000, multiplied by 100, resulting in an 8% churn rate.
Revenue Churn Formulas
Revenue churn evaluates how much recurring revenue a company loses from its existing customer base. It can be measured as gross revenue churn or net revenue churn.
Gross Revenue Churn
Gross Revenue Churn = (Lost Revenue ÷ Starting Revenue) × 100
Net Revenue Churn
Net Revenue Churn = ((Lost Revenue − Expansion Revenue) ÷ Starting Revenue) × 100
Net revenue churn can be negative when expansion revenue from upgrades and additional purchases is greater than the revenue lost through cancellations or downgrades. Negative net revenue churn is generally a positive business outcome.
Understanding Your Churn Rate
Churn performance varies by business model, customer type, contract length and reporting period. The following table provides a general interpretation rather than a universal industry benchmark.
| Churn Rate | General Interpretation | Suggested Action |
|---|---|---|
| Below 2% | Strong customer retention | Maintain service quality and monitor changes |
| 2% to 5% | Moderate customer loss | Review feedback and strengthen engagement |
| 5% to 10% | Potential retention concern | Investigate cancellation reasons and customer experience |
| Above 10% | High customer loss | Prioritize retention, product value and support issues |
How to Reduce Customer Churn
Businesses can reduce churn by improving customer onboarding, resolving support issues quickly, monitoring product usage, collecting cancellation feedback and communicating product value throughout the customer relationship.
Segmenting churn data is also important. Review churn by pricing plan, acquisition source, customer age, location and product usage to identify which customer groups require the most attention.
Frequently Asked Questions
Churn rate is the percentage of customers or recurring revenue lost during a specific period, such as a month, quarter or year.
Divide the number of customers lost during the period by the number of customers at the beginning of the period, then multiply the result by 100.
Churn measures customers who leave, while retention measures customers who remain. In a basic calculation, a 6% churn rate corresponds to a 94% retention rate.
New customers should be separated from the starting customer base. This calculator accounts for them when determining how many existing customers were lost.
Yes. Net revenue churn becomes negative when expansion revenue from retained customers is greater than revenue lost from cancellations and downgrades.
Many subscription businesses calculate churn monthly. Businesses with longer contracts may also review quarterly or annual churn to understand longer-term trends.
Generally, lower churn indicates stronger customer retention. However, churn should be evaluated alongside customer value, profitability, acquisition cost and revenue growth.
