Promoter, detractor and neutral customers: how to act

What do promoters, neutrals and detractors mean?

Promoter, detractor and neutral customers are categories normally associated with responses to a Net Promoter Score (NPS) survey. On a scale from 0 to 10, responses of 9 and 10 are classified as promoters; 7 and 8 as neutrals or passives; and 0 to 6 as detractors. The classification describes a response given in a particular context and moment — not a permanent personality. To take action, the company must understand the reason for the score, the point of the journey being evaluated and other behavioral signals.

Where do these categories come from?

The NPS method starts from a recommendation question, usually phrased as: “On a scale from 0 to 10, how likely are you to recommend the company, product or service to a friend or colleague?”. The methodology published by the Net Promoter System, from Bain, groups responses as follows:

• Promoters: scores 9 or 10;
• Neutrals or passives: scores 7 or 8;
• Detractors: scores 0 to 6.

These names are calculation conventions. A person may answer 9 after one service interaction and 6 after another experience. Product, channel, expectation, timing, price and the moment of collection can change the evaluation.

Therefore, prefer saying “responded as a promoter in this survey” rather than “is a promoter”. This wording reduces labeling and keeps analysis tied to evidence.

How to calculate NPS?

The calculation uses the proportion of valid responses from each group:

NPS = percentage of promoters − percentage of detractors

Neutral responses are included in the total used to calculate the percentages, but they are not added or subtracted directly. The result can range from −100, if all responses are detractors, to 100, if all are promoters.

Hypothetical example

Imagine a survey with 100 valid responses:

In this example, NPS = 55% − 20% = 35. The number is a simulation, not a benchmark or a universal goal.

What NPS shows — and what it does not show

NPS summarizes the distribution of responses to the recommendation question. It can help track perception, locate problematic moments and organize feedback. However, it does not by itself explain why a score changed nor prove loyalty, repurchase, retention or growth.

An academic review published in the International Journal of Market Research argues that the usefulness of NPS depends on context and that loyalty has behavioral and attitudinal dimensions not fully captured by the recommendation question.

To interpret the result, combine:

• open comment explaining the reason for the score;
• product, channel and stage evaluated;
• date and proximity to the event;
• response rate and profile of respondents;
• repurchase, frequency, churn and retention;
• complaints, resolution and customer effort;
• price, product, timing or operational changes.

Avoid comparing surveys with different audiences or moments as if they were equivalent. A post-service survey and a relationship survey measure distinct contexts.

How to listen to customers who responded as detractors

A score of 0 to 6 signals low willingness to recommend in that context, but does not automatically reveal severe dissatisfaction or intent to cancel. The comment and history help set priorities.

1. Acknowledge the feedback: thank them without arguing about the score or pressuring for a change.
2. Understand the facts: ask what happened, when and what outcome was expected.
3. Classify the cause: product, service, timing, billing, communication or another topic.
4. Correct when possible: inform the responsible party, next action and a realistic deadline.
5. Close the loop: confirm the resolution and record the learning.
6. Address systemic causes: group similar reports and fix processes, not just individual cases.

Do not offer a reward only to obtain a higher score. Compensation may be appropriate in the face of a failure, but it should be tied to the problem and company policies, not to manipulating the survey.

How to understand neutral or passive customers

Scores 7 and 8 do not mean indifference, lack of loyalty or inevitable risk. Many people consider these scores positive. The meaning depends on culture, expectation and survey wording.

To understand the group:

• ask what was missing for a better experience;
• identify recurring themes in comments;
• compare usage, repurchase and support without presuming intent;
• observe differences by product, channel and stage;
• prioritize improvements that add value for multiple customers.

The goal should not be “convert an 8 to a 9” at any cost. Actions should improve the experience element that prevented a more positive rating.

How to engage customers who responded as promoters

Scores 9 and 10 indicate a high declared likelihood of recommendation in that collection. This does not mean the person has already referred someone, will repurchase or will agree to participate in a campaign.

Possible actions:

• thank them and ask which aspect generated value;
• preserve the praised elements;
• invite, without pressure, to give a review, testimonial or participate in an additional survey;
• offer voluntary participation in a community or product test;
• present a referral program only when there are clear rules and consent;
• monitor whether declared recommendation turns into observed behavior.

Respect purpose, consent and communication preferences. A good score does not authorize public use of the customer’s name, testimonial or data.

Action table by group

How to collect comparable responses

• Define the object: company, product, service or experience.
• Choose the timing: keep a consistent window after the event.
• Use the correct scale: present 0 to 10 with clear anchors.
• Include an open question: ask for the main reason for the score.
• Avoid leading language: do not explain which score the team wants to receive.
• Control duplication: define frequency and triggering event for sending.
• Watch representativeness: record invitees, responses and differences between groups.
• Protect data: limit access, purpose and retention time.

If the team selects only satisfied customers or conditions service on the score, the indicator loses usefulness.

Common interpretation errors

• calling the categories permanent customer types;
• using NPS as a synonym for satisfaction, loyalty or retention;
• ignoring neutrals because they are not directly subtracted;
• looking only at the final average and discarding comments;
• comparing periods with different samples or moments;
• attributing all change to a recent campaign;
• pressuring customers or employees for high scores;
• promising to turn all detractors into promoters;
• acting individually without fixing recurring causes.

Loyalty programs do not replace fixing the experience

Points, cashback or benefits can recognize relationships, but should not hide product, service or billing failures. Before offering incentives to someone who responded with a low score, understand and fix the cause.

When the basic experience is consistent, a program can be part of the relationship. The choice between models should consider behavior, frequency and margin; see the guide on loyalty program models.

Use the categories to guide questions, not to label people

Promoters, neutrals and detractors summarize recommendation responses in a specific collection. The value of the method appears when the company investigates reasons, closes the feedback loop and relates perception to real behavior.

Track NPS as one among several pieces of evidence. Listen to detractors responsibly, understand what limits neutral ratings and preserve perceived value from promoters — without assuming a score permanently defines the customer.
