What is churn: Answer Guide 2027
Churn is the rate at which customers stop doing business with a company — usually measured as the percentage of subscribers or revenue lost over a period. Low churn signals product stickiness and predictable revenue; high churn means the company is filling a leaky bucket. In a churn interview, define it, distinguish logo churn from revenue churn, and explain why investors watch it so closely.
What This Tests in a Churn interview Question
- Whether you know the basic definition and can express it as a rate over a defined period.
- Whether you distinguish logo (customer count) churn from revenue churn — losing small customers hurts less than losing large ones.
- Whether you connect churn to valuation: retention drives lifetime value, which drives what a business is worth.
How to Answer a Churn interview Question
- Define it simply: the share of customers or revenue lost in a period, then split logo churn versus revenue churn.
- Explain why it matters: churn is the inverse of retention, and retention compounds into lifetime value and valuation.
- Show practical sense: mention levers that reduce churn — onboarding, customer success, annual contracts, product stickiness.
Example phrasing: "Churn is the rate at which customers leave — say 5% of logos per month. I would distinguish logo churn from revenue churn, since losing enterprise accounts hurts more, and note that low churn underpins high lifetime value, which is why investors prize net revenue retention above 100%."
Common Mistakes in a Churn interview Question
- Defining churn vaguely without a time period — a rate is meaningless without one.
- Confusing churn with downgrades or contraction; pure churn is customers leaving entirely.
- Ignoring the link to unit economics and valuation, which is the real reason interviewers ask.
Churn sounds like a simple vocabulary question, which is exactly why it trips people up — interviewers use it as a springboard into unit economics. Define it crisply, bridge to retention and LTV yourself, and you steer the conversation onto strong ground.

FAQ
What is churn in a churn interview context?
The rate at which customers or revenue are lost over a period — the inverse of retention.
What is the difference between logo churn and revenue churn?
Logo churn counts customers lost; revenue churn counts revenue lost. A company can lose many small logos yet keep revenue churn low.
Why do investors care about churn?
Because retention compounds: low churn means higher customer lifetime value and more predictable, valuable revenue.
What is a good churn rate?
It depends on the business model and segment — benchmarks may vary by role and region, so frame answers relatively rather than citing a universal number.
