Customer Health Score Calculator
Calculate a Customer Health Score in seconds — combining product usage, NPS, payment history, and support tickets. The CS manager early-warning metric to predict churn 60-90 days before it happens.
What Is Customer Health Score?
Customer Health Score is a composite metric (typically 0-100 or Red/Yellow/Green) combining behavioral signals to predict churn risk. Top SaaS companies (Gainsight, ChurnZero) build it from product usage frequency, NPS, payment timeliness, support ticket sentiment, and contract metadata. A score below 40 (or Red) predicts churn within 90 days with ~70% accuracy.
The Four Pillars of Health
1. Product Usage: weekly active users / licenses, depth of feature adoption. 2. NPS / Survey Sentiment: latest verbatim and trend. 3. Financial: payment timeliness, contract size trend. 4. Support: ticket volume, severity, response satisfaction. Weight each pillar by what historical churn data shows is most predictive for your product. Usage is typically 40-50%, sentiment 20%, support 15%, financial 15%.
From Health Score to Action
Red (0-40): immediate Executive Business Review (EBR) + adoption intervention. Yellow (40-70): proactive outreach, training, success plan refresh. Green (70-100): expansion play — upsell, multi-year renewal, advocacy ask. Without a clear action playbook tied to score bands, health scores become reporting theater. The score is only useful if it triggers behavior.
Common Health Score Mistakes
Mistake 1: too many signals diluting the score. Start with 4 signals max. Mistake 2: not back-testing against actual churn. Mistake 3: treating score as static — it must update at least weekly. Mistake 4: ignoring product usage for sentiment-only scores. Behavior beats stated intent. Customers say they're happy then churn — but stopping logins predicts it 60 days ahead.

Frequently Asked Questions
What is a healthy customer health score?
70+ on a 100-point scale signals Green (expansion ready). 40-70 is Yellow (at risk, proactive outreach needed). Below 40 is Red (high churn probability within 90 days).
How often should I update the score?
Weekly minimum for most B2B SaaS. Daily updates for product-led growth motions where usage signals shift fast. Static or monthly scores miss early warning signals.
How do I weight the signals?
Product usage typically gets 40-50%. NPS / sentiment 20%. Support 15-20%. Financial 15%. Back-test against your historical churned accounts \u2014 adjust weights based on which signal led the churn most reliably.
Does NPS alone work?
No. NPS only captures stated intent. Customers say they're happy then churn. Combine NPS with behavioral data (usage, logins, feature adoption) for predictive power. Behavior beats intent every time.
