Customer health score calculator

Score each of six signals from 0 to 100 and the calculator applies standard weights to produce one overall health score — with a breakdown showing exactly which signal is dragging the number down.

Runs entirely in your browser — real, deterministic math. Nothing is uploaded, stored or sent anywhere.

Score each signal 0–100

Move the sliders to match how a customer is doing. Weights sum to 100% and reflect what predicts retention in most B2B books.

Why it matters

Why a single health number works

Account managers hold paragraphs about their accounts in their heads; health scores compress them into numbers that can be sorted, trended and alerted on. The trend is the signal — the number is just the scoreboard.

One list, sorted by risk

With two hundred accounts, attention goes where the score says it should — not where the loudest voice or the freshest memory points. The bottom 20% holds most of the churn.

The recipe must be visible

A score nobody can decompose is a score nobody trusts. Showing which signal moved — and by how much — turns the number into a conversation about causes, not arguments about the score.

Act on the band, watch the trend

Bands trigger actions: at-risk gets a call this week, healthy gets watched for drift. A declining trend inside the healthy band matters more than the level itself.
