Churn rate
The short answer
Churn rate is the percentage of customers who stop using or paying for your product during a period. If 80 of 2,000 subscribers cancel in a month, monthly churn is 4%.
Churn compounds: 4% monthly churn means losing roughly 40% of customers over a year. Small improvements in churn produce large improvements in LTV.
Where churn comes from
- Never activated — users who didn't reach value
- Poor experience — product, delivery or support problems
- Price — perceived value below cost
- Competition
- Involuntary churn — failed payments
Reducing churn
- Improve onboarding and activation
- Recover failed payments with retries and reminders
- Ask why people leave, and fix the top reasons
- Offer pauses or downgrades instead of cancellation
- Win back lapsed customers with a genuine reason to return
In practice
Involuntary churn — failed card or mandate payments — is often a meaningful share of subscription churn and the easiest to fix: smart retries, reminders before the payment date and an easy way to update payment details. Tackle it before spending on win-back campaigns.
Churn rate formula and example
Customer churn rate = customers lost during the period ÷ customers at the start of the period. A gym with 500 members on 1 June that loses 40 by 30 June has an 8% monthly churn rate. Revenue churn uses lost recurring revenue instead of customer counts. See retention rate.
Churn rate in practice
A subscription service starts the month with 1,000 subscribers and loses 50: monthly churn is 5%. Reducing churn to 4% extends average customer lifetime and raises LTV.
How to reduce churn
- Improve onboarding and early value
- Identify at-risk customers early
- Offer pauses or downgrades instead of cancellation
- Ask leaving customers why
Common churn mistakes
- Measuring churn only annually
- Ignoring involuntary churn from failed payments
- No exit surveys
Frequently asked questions
Is churn relevant for non-subscription businesses?
Yes — define a lapse window based on normal purchase frequency and track customers who pass it.
What's the difference between customer churn and revenue churn?
Customer churn counts lost customers; revenue churn counts lost recurring revenue. Losing a few large customers can mean low customer churn but high revenue churn.
What causes churn?
Poor onboarding, low perceived value, product problems, better alternatives and life changes. Exit surveys and usage data reveal the main causes.
Is negative churn possible?
Yes — net revenue churn becomes negative when expansion revenue from existing customers exceeds revenue lost to cancellations.
What's the difference between churn rate and retention rate?
They're complements: if monthly retention is 95%, churn is 5%.
How does churn affect marketing?
Higher churn lowers LTV, which limits how much you can spend to acquire customers.
What is involuntary churn?
Customers lost because payments fail, not because they chose to leave.
How do we predict churn?
Look for early signals such as reduced usage or support complaints.
