How to Choose a North Star Metric: Steps, Inputs and Tools
Last updated: November 2026
To choose a North Star Metric for your product, list the moments where customers get real value, turn each into a countable metric, and score the candidates on five tests: it reflects customer value, it leads revenue, your teams can move it, everyone understands it, and you can measure it reliably. Pick the winner, write a precise definition, and break it into three to five input metrics that teams own.
NSM stands for North Star Metric: the single metric that best captures the core value your product delivers to customers. If you want the full background, including why revenue is a poor North Star and how an NSM differs from the One Metric That Matters, read our explainer What is a North Star Metric (NSM)? This post is the practical follow-up: how to pick one, build the metric tree, track it, and roll it out.
Key takeaways
NSM means North Star Metric. It is one metric that measures the value customers get, used to align every team.
Amplitude, publisher of the North Star Playbook, says a good North Star aligns to customer value, represents your strategy, and is a leading indicator rather than a lagging one like revenue (Amplitude).
Support the NSM with three to five input metrics, often based on breadth, depth, frequency and efficiency (Amplitude).
A precise definition (what counts, per what time window, for which users) matters as much as the choice of metric.
You don't need a special tool: product analytics (Amplitude, Mixpanel, PostHog) or a BI tool (Looker Studio, Power BI, Tableau) on top of your data both work.
What makes a good North Star Metric?
Use these five criteria as a scorecard. A candidate that fails one of them is usually the wrong choice.
It measures customer value, not company value. It rises when customers get what they came for. Amplitude calls this the "aha moment" and warns that metrics like registered users say little about what customers value (Amplitude).
It leads revenue. When it goes up this quarter, retention and revenue should follow later.
Teams can influence it. Product, marketing and customer success should each see how their work moves it.
It is easy to explain. If you need a slide to define it, it is too complex. Composite scores usually fail here.
You can measure it reliably and often. Weekly or monthly, from data you trust, without manual work.
Amplitude also suggests identifying which "game" your product plays: an attention game (time spent), a transaction game (number of transactions) or a productivity game (how efficiently people get work done) (Amplitude). Knowing your game narrows the shortlist quickly.
How do I choose a North Star Metric for my product, step by step?
Step 1: Write down the value moment
Finish this sentence: "A customer gets value from us when they ___." For a scheduling tool, it might be "a meeting gets booked without back-and-forth." For an ad agency, "a client's campaign hits the result we promised." Write two or three versions and keep the one closest to the customer's goal, not your feature.
Step 2: Turn it into three to five candidate metrics
Translate each value moment into something countable. Vary the unit (users, accounts, actions) and the time window (week, month). For example: "accounts that booked 3+ meetings this week" or "meetings booked per week."
Step 3: Score the candidates
Score each candidate 1–5 on the five criteria above. Do it as a group with product, marketing, sales and leadership in the room, because disagreement here reveals hidden assumptions.
Candidate | Value | Leading | Influence | Clarity | Measurable |
|---|---|---|---|---|---|
Sign-ups per month | 1 | 2 | 4 | 5 | 5 |
Accounts with 3+ bookings per week | 5 | 4 | 4 | 4 | 4 |
Customer health score | 4 | 3 | 2 | 1 | 3 |

Step 4: Validate it with your own data
Compare customers who hit the candidate threshold with those who don't. Do they retain better, expand more or churn less over the following months? If the line between them is weak, the metric isn't a real North Star. Check that it also drops when value drops, for example after an outage or a bad release.
Step 5: Write a precise definition
Most NSM arguments are really definition arguments. Document:
Name in plain language
Formula: exactly what is counted, and the unit (user, account, team)
Time window: per week, per month, rolling 28 days
Inclusions and exclusions: test accounts, internal users, free vs paid
Data source and owner: where it comes from and who answers questions about it
Step 6: Set a baseline and a target
Measure the last six to twelve months to see the trend and seasonality, then set a target for the next quarter. Without a baseline, every change looks like progress.
What are North Star input metrics (and how do you build a metric tree)?
Teams rarely move the North Star directly. They move inputs: the smaller metrics that, combined, drive the NSM. Mapping them gives you a metric tree, with the North Star at the top, inputs below it, and the work that moves each input at the bottom.
Amplitude suggests three to five inputs that are influential, complementary and directly actionable, and often structured along four dimensions (Amplitude):
Breadth: how many users or accounts get value
Depth: how much of the product they use
Frequency: how often they come back
Efficiency: how quickly they reach value
How to build your tree
Put the NSM at the top with its exact definition.
Ask "what has to be true for this to go up?" and write the answers as metrics.
Check each input against breadth, depth, frequency and efficiency so you don't miss a lever.
Assign one owner per input, usually a team.
Under each input, list the initiatives in your backlog that should move it.
That last step is where the tree becomes useful day to day. If you keep a marketing backlog, tag each idea with the input it should move, and prioritize the ideas that move the inputs furthest from target.
North Star Metric examples for marketing teams and agencies
The examples below are illustrative. They show how the method works for different business models and are not metrics used by any specific company.
B2B SaaS marketing team
NSM: target accounts that reach an activated trial or qualified opportunity per month
Inputs: target accounts engaged (breadth), contacts engaged per account (depth), touches per account per month (frequency), days from first visit to opportunity (efficiency)
Ecommerce brand
NSM: customers placing a second order within 90 days
Inputs: new first-time customers, share who open post-purchase emails, products per order, days to second order
Marketing agency
NSM: active clients hitting their agreed monthly KPI target
Inputs: clients with verified tracking on every channel (breadth), channels optimized per client (depth), tests launched per client per month (frequency), days from brief to launch (efficiency)
Notice what is missing: ROAS, impressions and ad spend. They are useful channel metrics, but they measure activity or efficiency, not whether the customer got the outcome they pay for. For channel-level reference points, see our Google Ads and LinkedIn Ads benchmarks.
What are the best tools for tracking a North Star Metric?
There is no dedicated "North Star tool" you must buy. Pick based on where your value moment happens and where your data lives.
Product analytics tools
Best when the value moment happens inside your product, because they track user behavior as events.
Amplitude: the company behind the North Star Playbook, with event-based analytics for products.
Mixpanel: offers Metric Trees, which map how input metrics drive output metrics and show correlations between them. It is a paid add-on on the Enterprise plan (Mixpanel Docs).
PostHog: a product analytics platform, also usable for event-based NSM tracking.
Web analytics
Google Analytics 4: works when your value moment is a website action. Mark it as a key event, the GA4 term for actions important to your business (Google Analytics Help).
BI and dashboard tools
Best when the NSM combines sources, such as CRM, billing and ad platforms, or when you need one company-wide dashboard.
Looker Studio for free dashboards on Google and other data sources
Metabase for SQL-based dashboards on your own database
Decision rule
If your value moment is... | Start with |
|---|---|
Inside your app or SaaS product | Product analytics |
A website action (purchase, booking, lead) | GA4 key event, plus a BI dashboard |
Spread across CRM, billing and channels | BI tool on a central data source |
A client outcome (agencies) | BI dashboard or campaign workspace per client |
For marketing teams, the inputs often sit in campaign data. A workspace like AdBacklog, which keeps campaigns, budgets and results across channels together with your backlog, makes it easier to see which planned work is meant to move which input.
How do you roll out a North Star Metric?
Week 1–2: decide. Run the scoring workshop, validate with data, and get leadership sign-off on the definition.
Week 3–4: instrument. Build the dashboard, check the numbers against a manual count, and fix tracking gaps.
Month 2: assign. Give each input an owner and a quarterly target. Tie team goals or OKRs to inputs, not to the NSM itself.
Month 2–3: build the rhythm. Review inputs weekly in team meetings and the NSM monthly with leadership.
Every quarter: review. Is the NSM still predicting retention and revenue? Are the inputs still the right levers?
What are common mistakes when choosing a North Star Metric?
Choosing before defining value. Teams pick a metric they already track, then justify it.
Vague definitions. "Active users" with no action, time window or unit leads to three versions of the truth.
Too many inputs. Ten inputs is a dashboard, not a tree. Stay at three to five.
Skipping validation. A metric that doesn't predict retention will steer you confidently in the wrong direction.
Using channel metrics as the North Star. ROAS or CTR can rise while customers get less value.
No owners. If nobody owns an input, nobody moves it.
Frequently asked questions
What does NSM stand for in business?
In product and growth contexts, NSM stands for North Star Metric: the single metric that best captures the value customers get from your product. See What is a North Star Metric (NSM)? for the full explanation.
What is the NSM full form?
The full form of NSM is North Star Metric. It is part of the North Star Framework, which pairs one guiding metric with a small set of input metrics.
How many input metrics should a North Star have?
Three to five is the common recommendation (Amplitude). Fewer and you miss levers; more and focus disappears.
Can a marketing team have its own North Star Metric?
Yes, as long as it connects to the company NSM. A marketing North Star should measure customers reaching value, such as qualified accounts that activate, not just leads or clicks.
What is the best tool to track a North Star Metric?
Use product analytics if value happens in your product, and a BI tool if the metric combines several data sources. The best tool is the one your data already flows into reliably.
Conclusion: pick it, define it, break it down
Choosing a North Star Metric is a short process with a long payoff: define the value moment, score candidates, validate with data, write a precise definition, and build three to five owned inputs. Then connect your planned work to those inputs, so every campaign and task has a clear reason to exist.
