Net Promoter Score Scale: Ranges & Benchmarks (2026)

The Net Promoter Score scale is the 0 to 10 rating customers use to answer one question: how likely they are to recommend a company, product, or service to a friend or colleague. Their answer sorts them into three groups, detractors (0 to 6), passives (7 to 8), and promoters (9 to 10), and those groups produce a single score from -100 to +100. Omniconvert has measured how loyalty signals like NPS connect to retention and revenue across the CROBenchmark dataset of 7,000+ websites in 15+ industries, against 300+ audit criteria, over 13 years in eCommerce [CROBenchmark Report 2026, Omniconvert].

Nexus by Omniconvert is the AI eCommerce growth engine that collects NPS on this scale and ties each response to a customer's value, so the score becomes an action rather than a number in a report. This guide explains what the NPS scale is, how the 0 to 10 rating works, the -100 to +100 score range, what counts as a good score, how benchmarks differ by industry, how to interpret your result, the standard survey question, and how to act on it.

What is the Net Promoter Score scale?

Net Promoter Score was designed around a single survey question and a single scale, and that simplicity is the point. By asking everyone the same thing on the same 0 to 10 rating, NPS produces a number that can be compared between companies, between segments, and between time periods. The scale is not arbitrary: where a customer lands on it predicts whether they will stay, leave, or tell others.

The three groups behind the scale, promoters, passives, and detractors, each behave differently and deserve different responses. This guide focuses on the scale itself and what your score means; for a deeper look at the three groups and how to move customers between them, see promoters, passives, and detractors explained.

How the 0-10 NPS scale works

The 11-point scale maps to the three groups like this:

The asymmetry surprises people: a 7 or 8 is not a promoter, and the detractor band stretches all the way from 0 to 6. That design is intentional. A customer who gives a 6 is not mildly happy; they are unconvinced enough that they would not actively recommend you, which puts them at genuine risk. Treating anything below a 9 as a win is how teams talk themselves into a rosier read than the data supports.

The NPS score range explained

To calculate it, take the share of respondents who are promoters and subtract the share who are detractors. If 60% are promoters and 20% are detractors, your NPS is 40. The formula is simple:

Two things trip people up. First, passives do not appear in the subtraction, but they are still part of the denominator when you work out the percentages, so a pile of passives quietly drags your score down. Second, NPS is reported as an integer, not a percentage: a score of 40 is just 40, never 40%. For the full worked calculation with examples, see how to calculate NPS.

What is a good NPS score?

The standard interpretation, popularized by Bain and Company, who co-created NPS, gives you rough bands to read your score against:

Treat these as orientation, not targets. A score of 30 might be outstanding in a low-NPS industry and mediocre in a high-NPS one. The bands tell you whether your customer base leans positive or negative; your industry and your own history tell you whether the number is actually good for you.

NPS benchmarks by industry

It is tempting to chase a universal "good" number, but NPS benchmarks vary so much by sector that a single target is misleading. Subscription and software audiences, considered-purchase retail, fast-moving consumer goods, and financial services all sit in different ranges for structural reasons, not because one is better run than another. A few principles keep benchmarking honest:

• Compare within your industry: a score is only meaningful against businesses with similar customers and buying cycles.
• Mind the methodology: published benchmarks use different samples, regions, and survey timing, so treat cross-source comparisons as directional at best.
• Trust your own trend most: the same question, same 0 to 10 scale, and same audience measured over time is the cleanest benchmark you have.
• Watch the mix, not just the number: two companies can share an NPS of 30 with very different promoter and detractor splits, which call for different actions.

This is also where NPS connects to the wider picture of customer satisfaction metrics like CSAT and CES, which add context the single NPS number cannot carry on its own.

How to interpret your NPS scale results

The number is a starting point, not a verdict. A high NPS suggests a base of loyal customers likely to refer others, but it does not guarantee retention if you stop earning it. A low or negative score is a warning that detractors are accumulating faster than promoters, which threatens both repeat revenue and word of mouth. To interpret well:

• Read the split, not just the score: a thin layer of promoters over a wide detractor base is fragile, even at a positive number.
• Follow the trend: direction over several measurement periods says more than any single reading.
• Pair it with the why: the rating is quantitative, but the open-ended comment is where the action lives. This is qualitative research applied to loyalty.

Reliability matters as much as the number itself. A score built on a handful of responses can swing wildly from one survey to the next, so a small sample tells you very little even when the result looks dramatic. Collect enough responses for the score to be stable before you read too much into a change, and make sure the people who answer reflect your wider customer base rather than only your happiest or angriest buyers. The same statistical sampling discipline that protects an experiment protects an NPS reading.

The standard NPS survey question and scale

The question that defines the scale is deliberately fixed: "On a scale of 0 to 10, how likely are you to recommend our company, product, or service to a friend or colleague?" It is almost always followed by an open text question, "What is the main reason for your score?", which turns a rating into a reason you can act on. A few rules protect the integrity of the scale:

• Keep the 0 to 10 scale: swapping in a 1 to 5 or 1 to 10 scale breaks comparability with benchmarks and with your own history.
• Label the endpoints clearly: 0 as not at all likely and 10 as extremely likely removes ambiguity about what the numbers mean.
• Always ask why: the follow-up comment is what separates a vanity metric from a source of improvements.
• Time it well: ask after a meaningful experience, such as a delivery or support interaction, not at random.

Acting on your NPS score with Nexus by Omniconvert

Most NPS programs fail not at measurement but at follow-through: the score gets reported and nothing changes. Closing that gap means treating each band on the scale as a trigger for a specific play, detractors into recovery, passives into nudges, promoters into advocacy.

Nexus by Omniconvert is the AI eCommerce growth engine that makes the scale operational. It collects NPS on the standard 0 to 10 scale, then connects each promoter, passive, and detractor to that customer's order history and predicted value, so you can prioritize the at-risk detractors who are also high-value, route them into recovery, and turn your promoters into referrals and reviews. That is how a Net Promoter Score stops being a quarterly slide and starts compounding into retention and revenue, alongside the broader work of loyalty and retention.
