Quick answer
A north star metric is the single metric a company chooses because it best captures the value customers get from the product and leads long-term revenue. It is paired with a few input metrics that teams can influence directly.
Formula: north star = breadth × depth × frequency (for example, active teams × key actions per team per week)
What is a north star metric?
A north star metric is the one number a company chooses to represent the value customers get from its product. If it goes up, customers are getting more of what they came for, and revenue tends to follow. Teams then work on a handful of input metrics that drive it.
Five tests for a candidate
- Measures customer value, not just your activity (sign-ups, emails sent).
- Leads revenue. It moves weeks or months before revenue does.
- The team can move it through product and marketing work.
- Easy to explain in one sentence to anyone in the company.
- Measurable weekly, so you see change in time to act.
Sample examples
Three sample businesses (illustrative):
| Business | Weak choice | Better north star | Why |
|---|---|---|---|
| Team analytics tool | Sign-ups | Weekly active teams that viewed a report | Sign-ups say nothing about value; viewed reports do |
| Food delivery marketplace | Gross order value | Orders delivered on time per week | Late orders still count in order value; on-time orders are what customers want |
| Language learning app | Daily app opens | Learners completing three or more lessons a week | Opens can be pushed with notifications; completed lessons mean learning |
Break it into input metrics
A north star is usually breadth × depth × frequency. For the sample analytics tool:
weekly reports viewed = weekly active teams × reports viewed per team
4,200 = 1,200 × 3.5Each factor becomes an input with an owner: new teams activated (growth), teams retained week to week (product), reports per team (product and onboarding). A team can move its input this quarter; the north star shows whether the inputs add up.
Common mistakes
- Picking a vanity metric such as page views or registered users.
- Changing it every quarter. It loses its point as a long-term compass.
- No guardrails. Watch retention and support load so the north star is not pushed in ways that hurt customers.
Measure it with the same definitions every week; see DAU/MAU, retention and actionable metrics.
