SaaS Metric

Negative Churn

Definition

Negative churn (also called negative net revenue churn) is when expansion revenue from your existing customers exceeds the revenue lost to contraction and cancellations in the same period. The result: your installed base grows even with zero new customers. It is equivalent to net revenue retention above 100%, and it is one of the strongest signals of product-market fit and durable growth.

Formula

Negative churn occurs when: expansion MRR > (contraction MRR + churned MRR)
Equivalently: net revenue retention (NRR) > 100%

Benchmark

Achieving negative churn (NRR > 100%) is a strong outcome; best-in-class B2B SaaS reaches 120%+ NRR, driven by usage- or seat-based expansion.

How negative churn is possible

It sounds like a contradiction — how can churn be negative? The trick is that "net" churn nets expansion against losses. If the customers who stay expand their spend faster than other customers downgrade or leave, the net movement of revenue from your existing base is positive. Expressed as churn, that is a negative number; expressed as retention, it is above 100%.

Negative churn is most achievable with pricing that scales as customers get more value — per-seat, usage-based, or tiered models where success naturally leads to higher spend. A flat per-account price makes negative churn nearly impossible, because there is no built-in mechanism for accounts to grow. This is why expansion-friendly pricing is a structural growth lever, not just a packaging detail.

Frequently asked questions

What is negative churn?

Negative churn is when expansion revenue from existing customers exceeds the revenue lost to downgrades and cancellations, so the installed base grows even without new customers. It is the same thing as net revenue retention above 100%.

How do you achieve negative churn?

By combining strong gross retention with expansion that outpaces losses — typically through per-seat, usage-based, or tiered pricing where customers naturally spend more as they get more value. Flat per-account pricing makes it nearly impossible.

Is negative churn the same as NRR above 100%?

Yes. Negative net revenue churn and net revenue retention above 100% describe the identical situation from opposite directions — expansion exceeding contraction plus churn.
