Churn Rate
Customer loss percentage.
What does Churn Rate mean?
Churn rate measures the percentage of customers who stop using your product or service during a given period. It is one of the most critical metrics for subscription-based and SaaS businesses. A high churn rate signals dissatisfaction or competitive pressure, while a low churn rate indicates strong customer retention and product-market fit.
How to calculate Churn Rate
Churn rate is calculated with the formula: Churn Rate (%) = (Customers Lost / Customers at Start of Period) x 100. For example, if you start the month with 1,000 customers and lose 50, your churn rate is (50 / 1000) x 100 = 5%. The retention rate is simply 100% minus the churn rate. The average customer lifespan is estimated as 1 / (Churn Rate as a decimal) — so a 5% monthly churn gives an average lifespan of 20 months.
FAQ
A "good" churn rate varies by industry and business model. For SaaS companies, an annual churn rate of 5–7% is considered excellent, while monthly churn below 1% is a strong benchmark. E-commerce and consumer apps often see higher rates. The key is to track your churn over time and work to reduce it consistently.
Customer churn counts the number of customers lost, regardless of how much they paid. Revenue churn measures the lost recurring revenue from those customers. A business could have low customer churn but high revenue churn if its highest-paying customers are leaving, or vice versa.
Common strategies include improving onboarding, providing proactive customer support, gathering and acting on feedback, offering loyalty incentives, and regularly delivering product improvements. Identifying at-risk customers early through usage patterns or engagement scores can also help prevent cancellations.
Both are useful. Monthly churn gives you a more granular, actionable view of short-term trends. Annual churn provides a broader picture and is easier to compare across industries. Many businesses track both and convert between them for different audiences — investors often prefer annual figures, while product teams use monthly data.
Churn rate and LTV are inversely related. A lower churn rate means customers stay longer, increasing their lifetime value. The formula LTV = ARPU / Churn Rate (where ARPU is average revenue per user) directly shows this relationship. Reducing churn is one of the most effective ways to increase LTV.
