What is Subscription Analytics? Examples with GA4 and PlainSignal

Subscription Analytics is the practice of collecting, measuring, and interpreting data related to subscriber behavior, revenue, and retention in subscription-based businesses. By monitoring key performance indicators (KPIs) such as churn rate, monthly recurring revenue (MRR), customer lifetime value (CLV), and subscriber growth, companies can make data-driven decisions to boost growth and optimize pricing. Effective subscription analytics provides insights into which customer segments are most valuable, how pricing changes impact revenue, and where potential churn risks lie. Platforms like Google Analytics 4 (GA4) enable advanced event-based tracking, while PlainSignal offers a cookie-free, privacy-friendly alternative for simple analytics. Together, these tools help teams forecast revenue, refine marketing strategies, and improve customer retention through actionable insights. Implementing subscription analytics involves setting up tracking, validating data quality, and continuously refining measurement strategies to align with business goals.

Core Metrics in Subscription Analytics

Subscription analytics revolves around tracking metrics that reflect the health and growth of a subscription-based business. These core metrics help teams understand subscriber trends, forecast revenue, and pinpoint areas for improvement.

  • Subscriber growth rate

    Measures the percentage increase or decrease in the number of subscribers over a specific period.

    • Formula

      ((New Subscribers – Lost Subscribers) / Starting Subscribers) × 100

  • Churn rate

    Percentage of subscribers who cancel or do not renew within a given timeframe.

    • Formula

      (Lost Subscribers / Total Subscribers at Period Start) × 100

  • Monthly recurring revenue (mrr)

    Predictable revenue earned each month from active subscriptions.

    • Calculation

      Sum of recurring subscription fees from all customers in the month.

  • Customer lifetime value (clv)

    Estimated total revenue a subscriber will generate over their entire subscription period.

    • Calculation

      Average Revenue per User (ARPU) / Churn Rate

Implementing Subscription Analytics

Setting up subscription analytics involves defining key events, configuring tracking in your analytics tools, and integrating data sources to ensure a complete view of subscriber behavior.

  • Google analytics 4 (GA4) setup

    GA4 uses an event-based model allowing custom subscription events with parameters.

    • Event configuration

      Use gtag.js or Google Tag Manager to send events like subscription_start and subscription_renewal.

    • Custom dimensions

      Define parameters such as subscription_plan and renewal_status for deeper analysis.
