    What is Churn Rate and why is it critical?

    Churn Rate is the percentage of the customers you had at the start of a period who left during that period. In SaaS and subscription models churn is the silent killer of growth — every lost customer offsets a chunk of new sales and lowers real net growth.

    Churn is measured two main ways: Customer Churn on customer count, Revenue Churn on lost MRR/ARR. Enterprise tends to prefer Revenue Churn because it reflects the impact of larger accounts. Healthy SaaS targets monthly churn of 3-5% at SMB, below 1% at enterprise.

    The most effective ways to reduce churn are strengthening onboarding, tracking in-product activation metrics, running a proactive customer success motion and using predictive models like churn risk scoring to catch at-risk accounts early.

    //Frequently Asked Questions

    What is a good monthly churn rate?

    For SMB-focused SaaS, 3-5% monthly is acceptable. Mid-market targets 1-2%; enterprise, below 1%. Annually, sub-5-7% is considered good.

    Customer Churn vs. Revenue Churn?

    Customer Churn measures the number of lost customers; Revenue Churn measures lost MRR/ARR. Because larger accounts have outsized revenue impact, Revenue Churn is usually the more critical view.

    What is negative churn?

    When upsell and expansion revenue from existing customers exceeds lost revenue. Net revenue retention (NRR) then climbs above 100% and the company grows even without new customers.

    First step to reduce churn?

    Do a cohort analysis to see when churn happens. Early churn usually points to onboarding; late churn points to gaps in value delivery.
