What Is Churn? (User Churn Rate)
The share of users who leave an app or subscription during a given period — the mirror image of retention.
Book a free callChurn (User Churn Rate) shows what percentage of users at the start of a period have left the app or dropped their subscription by the end of it. It’s calculated as (Users Lost ÷ Users at Start of Period) × 100. Churn and retention add up to 100%: if monthly churn is 8%, monthly retention is 92%.
How is churn rate calculated?
Example: At the start of the month there were 12,000 active subscribers; by the end of the month, 960 of them had not renewed or continued their subscription → monthly churn of 8%.
A common mistake is adding new users acquired during the period to the denominator. In fast-growing products, this makes churn look artificially low and hides the real problem.
Voluntary vs. involuntary churn
| Voluntary churn | Involuntary churn | |
|---|---|---|
| Cause | The user deliberately leaves | The payment fails |
| Typical reason | Not finding value, price, competitors | Expired card, credit limit, bank decline |
| Where to fix it | Product, pricing, communication | Payment infrastructure, retry flow |
| Share | Usually larger | Can be 20-40% in subscription models |
Most teams overlook involuntary churn, yet it’s the cheapest win. With a smart retry (dunning) flow, card update reminders and diversified payment providers, you can recover a significant share of that loss — without touching the product at all.
How does churn affect LTV?
A concrete example: monthly ARPU is $150 and margin is 70%. With 10% monthly churn, LTV is $1,050. Cut churn to 8% and LTV rises to $1,312 — just a 2-point improvement increases user value by 25%. Creating the same effect on the acquisition side is far more expensive.
How to reduce churn
- Set up early warning signals. Behaviors like declining session frequency or not using core features show up weeks before users churn. Intervene proactively with these segments.
- Treat involuntary churn separately. Add a payment retry flow, card expiration reminders and alternative payment methods.
- Offer alternatives in the cancellation flow. Offering a pause, a downgrade or a discount instead of a straight cancellation saves a meaningful share of users.
- Collect cancellation reasons. A structured cancellation survey is one of the most valuable data sources for your product roadmap.
- Keep reminding users of the value. Recap messages that show what users got out of the product during that period raise renewal rates.
- Acquire the right users. Users who arrive with the wrong expectations churn fast; your creative’s promise has to match the product reality.
Frequently asked questions
What is a good churn rate?
It depends on the business model. For subscription-based mobile apps, a monthly range of 5-8% is widely considered acceptable; in enterprise SaaS the rate should be much lower. In mobile games, churn is naturally high and is read alongside the retention curve.
Are churn and retention the same thing?
They’re two sides of the same coin and add up to 100%. Retention measures who stays; churn measures who leaves. In practice, retention is used more often for games and consumer apps, and churn for subscription models.
Is it more profitable to reduce churn or to acquire new users?
Usually reducing churn. Keeping an existing user costs far less than acquiring a new one. And because churn sits in the denominator, improving it grows LTV disproportionately, which also creates headroom on the acquisition side.
