What is MRR Churn? Definition, Calculation, and Examples

Monthly Recurring Revenue (MRR) Churn is the percentage of revenue lost due to subscription cancellations and downgrades over a given period. Unlike customer churn, which counts lost accounts, MRR Churn focuses on the actual dollars lost, making it a critical metric for subscription-based businesses that measure revenue health. Tracking MRR Churn helps companies understand how much of their predictable revenue base is eroding each month. It is calculated by comparing the revenue lost in a period against the revenue at the beginning of that period. Businesses often distinguish between gross MRR Churn, which ignores expansions, and net MRR Churn, which factors in upgrades and cross-sells. By analyzing MRR Churn, companies can make data-driven decisions around customer success strategies, product improvements, and pricing models to drive sustainable growth.

Why MRR Churn Matters

Understanding MRR Churn helps businesses gauge the health of their subscription revenue and predict future growth or contraction.

  • Revenue impact

    MRR Churn quantifies the exact dollar amount lost from downgrades and cancellations, directly affecting the company’s recurring revenue.

  • Growth forecasting

    High churn rates can offset new sales, making it difficult to project net revenue growth accurately. Monitoring MRR Churn ensures more realistic forecasts.

  • Investor confidence

    Investors and stakeholders closely watch churn metrics; a stable or declining MRR Churn rate signals strong customer retention and business health.

How to Calculate MRR Churn

The basic formula measures the lost MRR for a period relative to the starting MRR. Variations distinguish between gross and net revenue impacts.

  • Gross mrr churn rate

    Gross MRR Churn focuses solely on revenue lost from downgrades and cancellations. Formula: (Churned MRR ÷ Starting MRR) × 100.

    • Churned mrr

      Total monthly revenue lost due to plan downgrades and cancellations.

    • Starting mrr

      Total recurring revenue at the beginning of the period.

  • Net mrr churn rate

    Net MRR Churn accounts for both losses and gains from existing customers. Formula: [(Churned MRR – Expansion MRR) ÷ Starting MRR] × 100.

    • Expansion mrr

      Additional revenue gained from existing customers upgrading or expanding their plans.

Tracking MRR Churn with Analytics Tools

You can track and calculate MRR Churn using analytics platforms like PlainSignal and Google Analytics 4 by sending revenue events and analyzing them in dashboards.

  • PlainSignal (cookie-free analytics)

    Insert the PlainSignal tracking snippet on your billing or subscription pages to capture cancellation and upgrade events. For example:

    <link rel="preconnect" href="//eu.plainsignal.com/" crossorigin />
<script defer data-do="yourwebsitedomain.com" data-id="0GQV1xmtzQQ" data-api="//eu.plainsignal.com" src="//cdn.plainsignal.com/plainsignal-min.js"></script>

    Then configure custom events like subscription_canceled, plan_downgraded, and plan_upgraded with revenue parameters to compute MRR changes.

  • Google analytics 4 (GA4)

    In GA4, enable Enhanced Measurement or send manual events for subscription changes:

    1. Use gtag or Google Tag Manager to fire purchase events with value (MRR amount) and currency on cancellations and upgrades.
    2. Create custom Explorations or Reports in GA4 to sum values for churned and expanded revenue, then apply the MRR Churn formulas.

Strategies to Reduce MRR Churn

Reducing MRR Churn requires proactive retention efforts, product enhancements, and flexible subscription policies.

  • Enhance onboarding

    Deliver personalized setups, tutorials, and resources so customers quickly realize value and are less likely to cancel.

  • Proactive customer success

    Monitor usage signals to identify at-risk accounts and intervene with support, training, or tailored offers before churn occurs.

  • Iterate on product feedback

    Gather customer feedback continuously and ship improvements that address pain points, boosting satisfaction and loyalty.

  • Offer flexible plans

    Provide downgrade or pause options instead of outright cancellation to retain some revenue and keep customers engaged.
