How to Build a Customer Health Score Model That Predicts Churn Before It Happens
Most customer health scores are green. Most churning customers were green three months before they left. This paradox exists because most health scores measure activity, not outcomes, and weight signals by intuition rather than by their actual predictive power.
Why most health scores fail
The typical health score adds up product logins, support ticket resolution time, and NPS, weights them equally, and produces a number. The problem is that these signals have very different predictive power. In many B2B SaaS businesses, the single strongest churn predictor is executive sponsor disengagement, which does not appear in any product usage dashboard.
Building a model that works
Step 1: Identify your real churn signals
Look at your last 20 churned customers and your last 20 renewed customers. For each, pull: product usage patterns in the 90 days before the decision, support ticket volume and severity, stakeholder contact frequency, contract changes, and payment behavior. Identify which signals differentiated the groups.
Step 2: Weight by predictive power
If executive sponsor contact frequency is 3x more predictive than product logins, weight it 3x higher. The Health Score Model Builder lets you input your signals and weights to see the resulting model.
Step 3: Segment your scoring
A startup customer with 10 seats behaves differently than an enterprise customer with 500 seats. Build segment-specific scoring models.
Step 4: Calibrate against outcomes
Back-test against historical data. If the model correctly identifies 70%+ of churned customers as at-risk 90 days before churn, it is working.

Frequently asked questions
What makes a good customer health score?
A good health score predicts retention and expansion outcomes. It weights signals by their actual correlation with churn, not by intuition.
What signals should a health score include?
Product usage depth (not just logins), support ticket severity, stakeholder engagement, contract expansion history, NPS trends, and payment behavior. Weight each by historical correlation with churn.
