Revenue Churn (MRR Churn)
Updated July 21, 2026
Percentage of recurring revenue lost from cancellations and downgrades.
Also known as: MRR churn, Monthly Recurring Revenue churn, Revenue churn rate, Gross MRR churn, Net MRR churn, ARR churn
Revenue churn, usually called MRR churn, is the share of recurring revenue a subscription business loses over a period from cancellations and downgrades within its existing customer base. It is measured in dollars of recurring revenue, not in accounts, which is what separates it from customer or logo churn. That distinction matters because the two can diverge sharply: a company can lose only a handful of accounts in a month and still take a heavy revenue hit if the accounts leaving are its largest ones, or shed many small accounts while its revenue base barely moves.
The metric comes in two standard forms. Gross revenue churn counts losses only: cancellations plus contraction from downgrades, and can never fall below zero. Net revenue churn nets those losses against gains from the same existing customers, subtracting expansion, upsell, and reactivation revenue. Net churn can go negative when expansion outpaces losses, a state widely described as negative churn, where the recurring-revenue base grows without adding a single new customer.
Revenue churn became standard SaaS and subscription vocabulary as MRR-based reporting spread through the operating and venture communities in the late 2000s and early 2010s. David Skok's SaaS Metrics 2.0 essay on his For Entrepreneurs blog was an influential early codification of the surrounding framework, including the negative-churn concept, and subscription-analytics vendors such as ChartMogul, Baremetrics, ProfitWell, and Stripe later standardized the formulas in their dashboards. It is nobody's proprietary coinage. Today finance, product, and growth teams treat it as a core health metric, often reporting it alongside its retention-oriented mirror image, Net Revenue Retention.
How MRR churn is calculated
Gross revenue churn rate is churned MRR plus contraction MRR, divided by MRR at the start of the period. Churned MRR is the recurring revenue from accounts that cancelled outright; contraction MRR is revenue lost when accounts stayed but moved to a cheaper plan, dropped seats, or reduced usage. Because it only sums losses, gross churn is always zero or positive.
Net revenue churn rate takes the same numerator and subtracts the gains generated by the existing base over the period: expansion MRR from upsells and seat growth, plus reactivation MRR from previously churned accounts that returned. The result is divided by starting MRR. New-customer revenue is deliberately excluded from both calculations, since churn is about what happens to the base you already have, not what sales adds on top.
Most teams compute the metric monthly on MRR. Businesses that sell mainly on annual contracts often run the identical gross and net logic on Annual Recurring Revenue instead, reporting ARR churn.
Gross vs. net revenue churn, and negative churn
The gross and net figures answer different questions and should be read together. Gross MRR churn measures pure leakage: how much recurring revenue drains out before any offset. It is the cleaner signal of product and payment problems because expansion cannot mask it. Net MRR churn measures the combined movement of the base, capturing whether growth inside existing accounts is large enough to cover what is lost.
When net churn drops below zero, the base is expanding on its own, a condition called negative churn and sometimes described as SaaS nirvana because recurring revenue compounds without new acquisition. Negative churn is a specific claim about net revenue churn being under 0 percent, not a loose synonym for low churn; a company can have very low gross churn and still be nowhere near negative net churn. Watching both prevents a healthy net number, propped up by a few large upsells, from hiding steadily worsening gross losses underneath.
Revenue churn vs. customer churn vs. NRR
Customer churn, or logo churn, counts the percentage of accounts that leave. Revenue churn counts the percentage of recurring dollars that leave. They move together only when the departing accounts are average-sized; they separate whenever churn concentrates in unusually large or unusually small customers. A business with enterprise and self-serve tiers can post reassuring logo churn while a single enterprise cancellation dominates its revenue churn for the quarter, which is why revenue-weighted churn is the figure investors scrutinize.
Net Revenue Retention is the same underlying MRR movement viewed from the retention side rather than the loss side. NRR takes starting MRR, adds expansion, and subtracts contraction and churn, expressed as a percentage of the start. It is roughly the mirror of net revenue churn: NRR above 100 percent corresponds to negative net churn. Teams tend to report churn when framing risk and leakage, and NRR when framing durability and expansion, but both describe one set of movements in the recurring-revenue base.
What revenue churn does and doesn't tell competitive teams
Revenue churn is computed from a company's own billing and subscription records. That makes it invisible from the outside: a competitor never publishes its MRR churn rate, and no monitoring tool can read it directly from a rival. For competitive intelligence, the value of the term is mostly as context: it explains why churn itself cannot be tracked against competitors and why the practical approach is to watch externally observable proxies for revenue-health stress instead.
Those proxies are the kind of signals a tool like meertrack surfaces: price cuts or new discount tiers on a pricing page, which often read as defensive responses to retention pressure; removed or downgraded features; layoffs and hiring freezes visible in job postings; funding news or a down round; and rising complaint volume or slipping sentiment on review sites. No single item confirms elevated churn at a rival. A cluster of them appearing together is the closest external analogue a competitor watcher gets to a company struggling to hold its recurring revenue.

Frequently Asked Questions
What is the difference between revenue churn and customer churn?
Customer churn, or logo churn, measures the percentage of accounts that leave in a period. Revenue churn measures the percentage of recurring-revenue dollars lost. They diverge whenever the accounts leaving are not average-sized. Losing one large enterprise customer can spike revenue churn while barely moving logo churn, and shedding many tiny accounts can do the opposite, which is why the two are tracked separately.
How do you calculate MRR churn rate?
Gross MRR churn rate is churned MRR plus contraction MRR from downgrades, divided by MRR at the start of the period. Net MRR churn rate subtracts expansion and reactivation revenue from the existing base before dividing by starting MRR. New-customer revenue is excluded from both, because churn measures what happens to the revenue base you already have, not what new sales add on top.
What is negative churn and how is it achieved?
Negative churn means the net revenue churn rate falls below zero: expansion, upsell, and reactivation revenue from existing customers exceeds everything lost to cancellations and downgrades. The recurring-revenue base grows without any new customer acquisition. It is achieved through upsells, seat and usage growth, and plan upgrades large enough to more than replace lost revenue, and it corresponds to Net Revenue Retention above 100 percent.
How does revenue churn relate to Net Revenue Retention?
They describe the same movement of the recurring-revenue base from opposite directions. Net Revenue Retention adds expansion to starting MRR and subtracts contraction and churn, as a percentage of the start. Net revenue churn is the loss-oriented view of that same math. NRR above 100 percent is roughly equivalent to negative net revenue churn. Teams cite churn to frame leakage and NRR to frame durability.
What is a good revenue churn rate for a SaaS company?
It depends on segment and stage. Benchmark sources generally treat lower monthly revenue churn as better for larger, enterprise-focused companies, with the strongest performers reporting under 1 percent per month, while SMB-focused products typically run higher because smaller customers cancel more readily. Reading gross and net churn together matters more than any single threshold, since a healthy net figure can hide worsening gross losses beneath expansion revenue.
