NPS calculator

NPS reflects the true level of customer trust and the potential for organic business growth. Find out how willing your audience is to recommend your brand—calculate your Net Promoter Score (NPS) with our online calculator.

What Is NPS and Why Is It Critically Important?

Net Promoter Score (NPS) reflects your customers’ willingness to recommend your brand, product, or service to their network. Calculating this metric allows you to evaluate real audience loyalty, forecast organic growth through word-of-mouth marketing, and detect customer churn risks early.

Without tracking NPS, a company only sees current sales figures without understanding the hidden sentiment of its audience—creating a risk of sudden market share loss due to unaddressed negative customer experiences.

Calculation Formula:

NPS = % Promoters (score 9–10) − % Detractors (score 0–6)

The score ranges from -100 to +100 points.

How Is the Audience Divided in an NPS Survey?

Customers are asked one classic question: “On a scale from 0 to 10, how likely are you to recommend us to a friend or colleague?” Based on their response, respondents are divided into 3 groups:

Promoters (score 9–10): The most loyal customers (“brand advocates”). They buy most frequently, have the highest LTV, and bring in new customers through recommendations.

Passives / Neutrals (score 7–8): Satisfied customers who lack emotional attachment. They can easily switch to competitors if offered a lower price or a discount.

Detractors (score 0–6): Dissatisfied customers. They are at high risk of churn and may spread negative reviews, damaging your company’s reputation.

What Is Considered a “Normal” NPS Score?

NPS scores can range from -100 (everyone is a detractor) to +100 (everyone is a promoter). The generally accepted benchmarks for business health are as follows:

  • Below 0: Critical situation. Dissatisfied customers outnumber supporters, damaging the brand’s reputation.
  • 0 – 30: Average / Baseline level. A loyal core exists, but the business needs to actively improve its service quality.
  • 31 – 50: Good result. The company enjoys a high level of trust and a steady stream of word-of-mouth referrals.
  • Above 50: Excellent score. A strong brand with a powerful community of advocates (typical for market leaders).

Which 3 Metrics to Consider When Analyzing NPS?

To get an objective picture, knowing just the overall score is not enough. Analyze the following components:

  • Response Rate: The percentage of customers who took part in the survey. For results to be relevant, they must be based on a sufficiently large sample (ideally 15–20%+ of your active customer base).
  • Ratio of Promoters to Detractors: Even with the same final NPS score (e.g., +20), a model with 30% promoters and 10% detractors is significantly healthier than one with 60% promoters and 40% detractors.
  • Open-Ended Comment Analysis (Reasons for Scores): The text feedback provided after selecting a rating gives direct insight into what causes delight or triggers frustration.

Most Common Mistakes When Measuring NPS

Measuring NPS Immediately After a Single Transaction: NPS measures overall brand perception, not impressions from a specific call or purchase (CSAT is used for that). NPS surveys should be conducted after a customer has used the product for a certain period.

Manipulating the Survey: Asking customers to leave “only 9s or 10s” or offering bonuses for high scores distorts the data and strips the metric of any practical value.

Failing to Act on Detractors: Collecting ratings without following up with dissatisfied users turns the metric into a useless number on a report.

When an NPS Calculator Will NOT Provide an Objective Picture

Small Sample Size (Fewer Than 50–100 Responses): On small datasets, a few random detractors can artificially lower the score by dozens of points.

Monopoly Market or Lack of Alternatives: If customers have no choices, they may stay with you and give high ratings simply due to the absence of alternatives, rather than genuine loyalty.

B2B with Multiple Decision-Makers (DMKs): Surveying only a junior manager or only a director fails to reflect the overall stance of the client company as a whole.

What to Do to Increase Your NPS Score?

  • Close the Loop with Detractors: Contact customers who gave a score of 0–6 within 24 hours. Resolving their issues promptly often converts detractors into brand promoters.
  • Work with Passives / Neutrals (Scores 7–8): Ask passive customers what specific improvements would be needed for them to give a 10, then implement their feedback.
  • Engage Promoters (Scores 9–10): Encourage your most loyal customers to write reviews on third-party platforms, participate in case studies, or join referral programs.
  • Systematize Feedback for Product Teams: Pass recurring complaints from detractors directly to development, support, or logistics teams to drive structural improvements.

The calculator provides an accurate benchmark, and we help you achieve these targets in practice. If your NPS is declining and detractors are creating negative sentiment around your brand, it is time to optimize customer experience.

FAQ

How Does NPS Differ from CSAT?

NPS (Net Promoter Score): Measures long-term customer loyalty and overall attitude toward the brand (evaluating whether a person is willing to recommend the company as a whole).

CSAT (Customer Satisfaction Score): Evaluates short-term satisfaction from a specific interaction (such as a product purchase, delivery experience, or a support call).

How Often Should You Conduct an NPS Survey?

For most business models, measuring NPS 1–2 times per year across the entire customer base is sufficient, or you can run continuous targeted surveys (e.g., sending a request to each customer 30–60 days after registration or product usage). Surveying too frequently annoys your audience and reduces the overall response rate.

Why Are Scores of 7 and 8 Considered "Neutral" and Excluded from the Formula?

Customers who rate a business 7–8 points are generally satisfied with the quality, but they lack an emotional connection to the brand. They will not become active “brand advocates” and can easily switch to a competitor offering a lower price. For this reason, they are added neither to promoters nor to detractors, although they are factored into the total number of survey responses.

What Response Rate Is Needed for a Relevant NPS?

For the B2B segment, a Response Rate of 25–40% is considered standard, whereas 10–20% is fully sufficient for B2C. If fewer than 5–10% of your audience responds, the final NPS score may be distorted, as feedback will come primarily from users with extreme experiences (either highly positive or highly negative).

How to Handle Detractors (Scores 0–6) to Improve Your Score?

Implement a Close the Loop protocol:

  • Automate Alerts: Automatically route detractor notifications directly to your customer support or management team.
  • Respond Within 24 Hours: Contact the customer promptly, uncover the root cause of their negative experience, and offer a resolution (such as a compensation, product replacement, or fast issue resolution).
  • Fix Systemic Issues: Address and resolve the underlying bottleneck in your business processes that triggered the complaint in the first place.
