Churn Rate

What is churn rate?

Churn rate is the percentage of subscribers who leave during a given time period. It is the single most watched health metric for subscription businesses because it directly determines whether the business is growing or shrinking.

The basic formula is: Churn Rate = (Subscribers Lost During Period / Subscribers at Start of Period) × 100. A monthly churn rate of 5% means that for every 100 subscribers at the start of the month, 5 did not renew.

Why small churn rates compound dramatically

Churn is deceptive. A 5% monthly churn rate sounds manageable, but compounded over a year it means losing over 46% of your subscriber base. To simply maintain the same number of subscribers, you would need to acquire nearly as many new customers as you started with.

This compounding effect makes even small improvements in churn rate extremely valuable. Reducing monthly churn from 5% to 4% can mean retaining hundreds or thousands of additional subscribers annually.

Segmenting churn for actionable insights

The most useful churn analysis separates voluntary churn (customer cancels) from involuntary churn (payment fails). It also segments by cohort (when the customer signed up), plan type, geography, and payment method. This segmentation reveals which churn is addressable through product improvements versus payment infrastructure improvements.

FlyCode directly reduces the involuntary component of churn rate by recovering failed payments before they result in canceled subscriptions.
