Churn Analysis: Logo vs Revenue Churn, Cohorts

Churn Analysis for Startups

Churn is the number that quietly decides whether a SaaS company is fundable. Growth hides bad churn for a while — then it doesn't.

Logo vs revenue churn

Logo churn = % of customers that left. Revenue churn = % of MRR that left. If small customers churn and large ones stay, revenue churn looks healthier than logo churn. Report both.

Gross vs net revenue retention

Gross retention caps at 100% — measures pure churn and contraction. Net retention adds expansion and can exceed 100%. Best-in-class SaaS: >90% gross, >120% net. Below 80% gross at Series A is a red flag.

Cohort curves tell the truth

Group customers by month of acquisition. Track retention over time. A flat cohort curve after month 3-6 = product-market fit. A cohort that keeps decaying = you don't have PMF, no matter what monthly churn shows.

Why churn matters more than growth

At 5% monthly churn, you're replacing your entire customer base every 20 months. Growth compounds; so does churn. Investors model out how much new ARR you need just to stand still — high churn means the treadmill is faster.

Frequently asked questions

What churn rate is acceptable at Seed?

SMB: <5% monthly is common. Mid-market: <2%. Enterprise: <1%. Below Seed, cohort trend matters more than absolute rate.

How do I lower churn quickly?

Fix onboarding for the first 30 days, identify at-risk accounts via usage signals, and interview every churned customer for 3 months.

Do investors care about voluntary vs involuntary churn?

Yes. Involuntary (failed cards) is fixable with dunning; voluntary is a product problem. Separate them in reporting.
