What churn rate measures
Churn rate is the percentage of paying subscribers who cancel during a fixed period (most commonly a month). For an auto-renewable subscription, churn happens when the user turns off auto-renew, gets a failed billing they do not recover, or is moved into the grace-period bucket and never returns.
The simplest formula:
monthly_churn = cancellations_in_month / paying_subscribers_at_start_of_month
If you start the month with 1,000 paying users and 50 cancel, monthly churn is 5%. Annualized that is roughly 46% (compounding monthly).
Why churn rate matters more than acquisition
Churn is the inverse of retention, and retention is what makes subscription apps compounding businesses. A 5% monthly churn rate means the average user lifetime is 20 months. A 10% monthly churn rate cuts that to 10 months. The same acquisition spend buys half the lifetime revenue.
This is why the standard LTV formula is LTV = ARPU / churn_rate. Churn sits in the denominator. Every point you shave off churn multiplies LTV.
What drives churn for mobile subscription apps
The usual suspects:
- Price-to-value mismatch. The user does not feel they got their money's worth at the local price. The single biggest lever for emerging markets.
- Onboarding friction. The user never reached the core value moment before the trial ended.
- Failed billing. Card declines, expired payment methods. Apple and Google have grace-period and billing-retry flows, but recovery rates vary.
- Competitive substitution. A cheaper or free alternative shipped between trial start and renewal.
- Feature fatigue. The user reached their goal and no longer needs the subscription. Common for fitness, language learning, productivity apps.
How does pricing affect churn?
Pricing affects churn in two opposing directions. A higher price filters for higher-willingness-to-pay users who tend to churn less (the self-selection effect). A localized PPP-tuned price brings in more users at a sustainable price-to-value ratio, which keeps churn rates closer to your US/EU baseline instead of spiking in markets where the FX-converted USD price feels punishing.
The net effect on revenue is almost always positive for localized pricing in lower-income markets, even though average churn rates per cohort can look slightly higher than the self-selected FX cohort.
What is a good churn rate for a mobile subscription app?
RevenueCat's State of Subscription Apps shows monthly churn rates for consumer apps clustered around 6 to 10 percent across most categories, with utility and entertainment apps trending higher and productivity / family apps lower. Anything below 5 percent monthly is excellent for consumer mobile, top decile.
How to measure churn correctly
A few traps:
- Voluntary vs involuntary churn. Voluntary is the user actively cancelling. Involuntary is a failed payment. Separate them; they have different fixes.
- Trial churn vs paid churn. Trial-to-paid conversion is a different metric. Real churn starts after the first paid renewal.
- Cohort vs aggregate. Aggregate monthly churn averages across cohorts. Use cohort retention curves to see real shape (year-1 vs steady-state).
- Per-country churn. If you sell globally, aggregate churn hides which markets are bleeding. Localized pricing decisions live or die on per-country churn trends.
Examples
Churn rate impact on lifetime value
Monthly ARPU of $5, varying churn rates:
| Monthly churn | Avg lifetime (months) | LTV at $5 ARPU |
|---|---|---|
| 3% | 33 | $165 |
| 5% | 20 | $100 |
| 7% | 14 | $70 |
| 10% | 10 | $50 |
| 15% | 7 | $35 |
Moving from 10% monthly churn to 5% doubles LTV without any change to ARPU. That is why churn reduction is usually the highest-ROI lever in a subscription business.
Frequently asked
What is a good churn rate for a subscription app?
RevenueCat's State of Subscription Apps shows monthly churn around 6 to 10 percent across most consumer mobile categories. Below 5 percent monthly is top-decile. Productivity and family-oriented apps tend to retain better than utility and entertainment.
How is churn rate calculated?
Divide cancellations in the period by paying subscribers at the start of the period. For monthly churn, take all cancellations in the month and divide by the month-start paid base. Separate voluntary churn (user-initiated) from involuntary (failed billing) for accurate measurement.
Does localized pricing reduce churn?
In lower-income markets, yes. A PPP-tuned price reduces the price-to-value mismatch that drives churn when users feel they overpaid in local currency. Aggregate churn can look slightly higher because you bring in more users, but per-cohort retention improves and total LTV grows.
What is the difference between churn rate and retention rate?
They are inverses. If monthly retention is 95 percent, monthly churn is 5 percent. Retention is what stays, churn is what leaves, and they always sum to 100 percent of the starting cohort for a given period.
