Net Promoter Score (NPS) is the single most-used customer experience metric in the world. It measures loyalty by asking one question: how likely are you to recommend us? This guide covers the scale, the formula, a worked example, what counts as a good score, and how to actually use NPS to improve your business.
The NPS question
NPS is calculated from responses to a single question, almost always phrased as:
"On a scale of 0 to 10, how likely are you to recommend [company / product] to a friend or colleague?"
Respondents pick a number from 0 (not at all likely) to 10 (extremely likely). The simplicity is the point: one question, one scale, comparable across companies, industries, and time periods.
The three response bands
Loyal enthusiasts. They keep buying, refer others, and stay through pricing changes. They are your single most valuable customer segment.
Satisfied but unenthusiastic. They are happy enough to stay for now, but they will switch the moment a better option appears. Passives are excluded from the score.
Unhappy customers who can damage your brand through negative word-of-mouth. They are also your fastest churn risk and your highest-priority recovery target.
The NPS formula
NPS = % Promoters − % Detractors
The result is a whole number between -100 and +100. Passives are counted in the denominator (your total responses) but not in the numerator.
Worked example
You send a survey and receive 200 responses:
- 120 promoters (60%)
- 50 passives (25%)
- 30 detractors (15%)
NPS = 60 − 15 = +45. That puts you firmly in the "great" band and well above most industry averages.
Try it yourself
Drop in your own response counts (or paste raw scores) to see your NPS instantly. The calculator uses the exact same logic the AwareCX platform uses internally.
NPS benchmarks by band
| Score range | Band | What it means |
|---|---|---|
| +70 to +100 | World-class | Top 1% of companies globally |
| +50 to +69 | Excellent | Strong loyalty, real referral engine |
| +30 to +49 | Great | Above most industry averages |
| 0 to +29 | Good | More promoters than detractors, room to grow |
| -30 to -1 | Needs work | More detractors than promoters |
| -100 to -31 | Critical | Severe trust gap, retention is at risk |
Industry benchmarks shift these expectations. Subscription consumer brands often run +50 or higher; B2B service businesses commonly land in the +20 to +40 range; ISPs and utilities historically run lower, around 0 to +30. Always compare to your own category.
Relationship NPS vs transactional NPS
The same metric can be used two ways. Relationship NPS is sent once or twice a year and measures overall loyalty to your brand. Transactional NPSis sent right after a specific interaction (a service call, an install, a renewal) and measures how that interaction shaped sentiment. Most mature programs run both.
Common NPS mistakes
- Treating an 8 as a win. An 8 is a passive. They are at risk.
- Surveying too often. Survey fatigue tanks response rates. AwareCX enforces cooldowns to prevent it.
- Reporting NPS without sample size. A score from 12 responses is noise. Always show n.
- Asking for the score and stopping there. The follow-up question ("why?") is where the value lives.
- Not closing the loop. Detractors who get a follow-up convert to neutral or promoter at far higher rates than detractors who are ignored.
How AwareCX uses NPS
AwareCX is built around NPS, CSAT, and CES as first-class metrics. Every survey automatically computes the score, segments responses into promoter / passive / detractor, flows detractors into the ResolveCX triage queue, and rolls the result into the portfolio-level Portfolio Health Score. You can compare NPS across accounts, time periods, and segments without manual calculation.
