# What Is Negative Churn?

> Negative churn occurs when revenue expansion from existing customers — upsells, cross-sells, and seat growth — exceeds revenue lost from churn and downsells, so the retained cohort grows in value over time.

**Negative churn** means your existing customer base generates more revenue over time than you lose to cancellations and contract shrinkage — the base grows even without new sales.

### How it works

Start with $1M ARR from last year's cohort. This year $80K churns off, but expansion adds $150K from upsells and seat growth. Net change: +$70K on the cohort — negative churn in dollar terms. Expressed as **net revenue retention (NRR)**, that cohort might show 107% if measured on the same customer set.

Negative churn is most common in B2B software with usage-based pricing, land-and-expand sales motions, or multi-product suites. Consumer subscriptions rarely achieve it at scale because expansion per user is limited.

The metric is usually calculated on a trailing twelve-month basis for a defined cohort — often all customers as of twelve months ago — not mixing new logos into the retention math.

### Why it matters

- **Founders:** Product and customer success teams should map expansion paths deliberately — pricing tiers, integrations, and account management — rather than hoping upsells happen accidentally.
- **Investors:** NRR above 100% signals that CAC payback improves over time as the base compounds. Due diligence checks whether expansion is concentrated in a few whale accounts or broad-based.

### Common mistake

Claiming negative churn while including new customer revenue in the retention calculation. NRR and negative churn apply to existing accounts, not net-new logos.

## FAQ

### What is Negative Churn in simple terms?

If your existing customers collectively spend more this year than last year even after some cancel, you have negative churn. Expansion from retained accounts outweighs losses from departed or shrinking ones.

### Why does Negative Churn matter?

For founders, negative churn means the installed base is a growth engine — you can grow without relying only on new logos. For investors, net revenue retention above 100% often correlates with durable SaaS economics and efficient growth.
