What Is a Customer Health Score?
A customer health score is a single metric that captures how likely a customer is to stay and grow. Essential for subscription and B2B businesses.
Key Takeaways
- A health score aggregates multiple signals into one number showing how 'healthy' a customer relationship is.
- Components typically include product usage, support contacts, NPS, payment behaviour, and engagement.
- Health scores enable proactive intervention before a customer reaches the point of churn.
What a health score is
A customer health score is a composite metric — typically 0 to 100 — that reflects the overall strength and trajectory of a customer relationship. It draws together multiple signals: how actively the customer uses the product, their NPS or satisfaction score, their payment history, engagement with your communications, and any support issues. The score tells you at a glance how each customer is doing.
Components of a health score
Product usage: is the customer actively using key features? Login frequency, feature adoption, and usage depth are strong signals for software products. Support: are they raising lots of issues? Escalations are a strong negative signal. Satisfaction: their last NPS or CSAT score. Financial: are they paying on time? Have they expanded their spend? Engagement: are they opening communications and attending any check-in calls?
How to weight the components
Weight each component based on how predictive it is of retention in your customer base. For a SaaS product, usage data is usually the strongest predictor and should carry the most weight. For a relationship-driven B2B service, satisfaction and engagement scores may matter more than platform usage. Test your weighting model against historical churn data to validate it.
Using health scores operationally
Customer success or account management teams use health score dashboards to prioritise their time. Red accounts (low health) get immediate attention. Amber accounts get proactive outreach. Green accounts get standard engagement. This triage approach ensures limited team capacity is directed at the customers most at risk — maximising retention with the resources available.
