NPS is deceptively simple — one question on a 0–10 scale — but the insight it surfaces predicts loyalty, churn risk, and word-of-mouth growth better than most survey types. This guide explains how it works, what your score actually means, and what to do with the results.
What Is NPS?
Net Promoter Score measures customer loyalty by asking one question: how likely are customers to recommend you to someone they know. Unlike satisfaction surveys that capture a momentary feeling, NPS measures something deeper — whether a customer's experience was strong enough that they would put their personal reputation behind recommending you.
The metric was developed at Bain & Company and published in 2003. It became an industry standard because it is easy to measure consistently over time, easy to benchmark against industry peers, and strongly correlated with revenue growth and retention rates.
How the NPS Question Works
The core question
Every NPS survey is built around one question, always worded the same way:
Respondents choose a number from 0 (not at all likely) to 10 (extremely likely). Based on their answer, every customer falls into one of three groups.
Calculating Your NPS Score
Worked example
You survey 100 customers and receive the following distribution:
An NPS of −20 means more detractors than promoters. There are more customers actively discouraging others than there are customers actively recommending you. This signals a loyalty problem that needs attention.
What Is a Good NPS Score?
NPS ranges from −100 (every customer is a detractor) to +100 (every customer is a promoter). Any positive score means more promoters than detractors, which is the baseline goal. Here is how the full range maps to real performance:
Industry context matters significantly. A score of 45 is strong for a telecom company, where industry averages often sit in the 20–35 range. The same score of 45 is below average for a consumer software product, where top performers regularly reach 60–70+. Always benchmark against your industry peers, not absolute numbers.
Track the trend, not the absolute. Do not obsess over whether your NPS is 42 or 45. What matters is direction: is your NPS rising or falling quarter over quarter? A rising NPS from a low base signals improving loyalty. A falling NPS from a high base is an early warning sign worth investigating immediately.
When to Send an NPS Survey
Measurement frequency
Quarterly is the standard cadence for most businesses. This is frequent enough to catch emerging trends but not so frequent that it causes survey fatigue among your customer base. Larger companies with significant customer volume sometimes measure monthly — using rotating samples so no single customer is surveyed repeatedly. Annual measurement is too slow: you will miss trends and have no early warning of loyalty problems.
When within the quarter
Send mid-quarter rather than at quarter-end when everyone is busy. Mid-morning on Tuesday through Thursday consistently gets the highest response rates. Avoid Monday mornings (inbox overload) and Friday afternoons (mentally checked out).
Who to survey
For companies with fewer than 500 customers, survey everyone. For larger populations, use a random sample — not just recent customers, which would create recency bias. Consider running separate NPS measurements for different product lines or customer segments. A company-wide NPS of 50 can hide a 70 in one product and a 25 in another, which are very different problems requiring very different responses.
The Follow-Up Question That Matters Most
The NPS question gives you a number. What turns that number into an action is the follow-up. Always add one open-ended question immediately after the NPS scale:
For detractors, a second targeted follow-up is valuable: "What would make you more likely to recommend us?" This is action-oriented — it tells you specifically what change would shift their loyalty, rather than just confirming they are unhappy.
Stop at two follow-up questions maximum. The power of NPS is its brevity. A three-question NPS survey consistently outperforms longer alternatives on completion rate and response quality.
NPS Best Practices
Segment your results
Break NPS down by customer segment immediately after collecting data. Meaningful segments to analyse: product line, customer size, tenure (new versus long-term), industry, geographic region, and support channel. Segmentation reveals where loyalty is strong and where it is weak — information a company-wide average actively conceals.
Close the loop with detractors
When a detractor submits feedback, reach out personally within 24 hours. Understand the specific problem. Take action where possible. Even when you cannot fix everything immediately, the fact that you responded and tried changes the relationship. This follow-through moves detractors toward passive or even promoter status more reliably than any product change.
Share results with your team
NPS improves when everyone in the organisation understands the score and why it matters. Share results across functions — not just customer success. Engineers who see NPS data often build differently. Support teams who see feedback themes respond differently. Make NPS a shared metric, not a leadership dashboard metric.
Do not game the score
Only send NPS surveys right after exceptional experiences. Only survey your happiest customers. These approaches inflate your score and destroy its predictive value. A dishonest NPS is not just useless — it is actively harmful, because it convinces leadership that loyalty is healthy when it is not.
