What Is a Customer Health Score?

Definition

A customer health score is a single metric that summarizes how likely a customer is to renew, churn or expand — blending signals like product usage, support tickets, engagement and survey sentiment. It gives Customer Success an early-warning system to act before a renewal is at risk.

Key takeaways

  • Health score combines usage, engagement, support and sentiment into one signal.
  • It flags at-risk accounts early — long before the renewal date.
  • There's no universal formula; weight the signals that actually predict churn for you.

Common health inputs

  • Product usage — breadth and depth of adoption
  • Engagement — logins, key actions, stakeholder activity
  • Support — ticket volume and severity
  • Sentiment — NPS, CSAT and qualitative signals

How to use it

A health score is only useful if it triggers action. Tier accounts into healthy / watch / at-risk, and attach plays to each tier — proactive outreach for red accounts, expansion conversations for green ones.
