What is Net Promoter Score?

Net Promoter Score, or NPS, is one of the most widely used measures of customer loyalty, and a big part of its appeal is how simple it is. You ask customers a single question, "How likely are you to recommend us to a friend or colleague?", and they answer on a scale from 0 to 10. From those answers you get one number that captures whether your customers are fans, fence-sitters, or critics.

Because it boils sentiment down to a single, comparable figure, NPS is easy to track over time and share across a team. It pairs naturally with other experience metrics like your CSAT score, which measures satisfaction with a specific interaction rather than overall loyalty.

How to calculate NPS

First, sort your responses into three groups based on their score, then take the percentage of promoters and subtract the percentage of detractors.

NPS = % Promoters − % Detractors
  • Promoters (9-10): loyal enthusiasts who keep buying and refer others.
  • Passives (7-8): satisfied but unenthusiastic, and vulnerable to competitors.
  • Detractors (0-6): unhappy customers who can hurt your brand through negative word of mouth.

Say you collect 100 responses: 60 promoters, 25 passives, and 15 detractors. That's 60% promoters and 15% detractors, so your NPS is 60 − 15 = 45. Passives still count toward your total, which is why they quietly pull the score down even though they aren't subtracted directly. The result always lands somewhere between −100 and +100.

What is a good NPS score?

As a rule of thumb: anything above 0 means promoters outnumber detractors, above 30 is good, above 50 is excellent, and above 70 is genuinely world-class. That said, benchmarks swing widely by industry, so the most useful comparison is against your own past scores and your direct competitors. A score climbing quarter over quarter is often more telling than the absolute number.

How to improve your NPS

The fastest gains usually come from two places: closing the loop with detractors before they churn, and removing friction from the experience, especially slow support. When customers wait hours for an answer, they slide from promoter to passive to detractor. Responding quickly and consistently is one of the most reliable ways to lift loyalty, which is why so many teams lean on automation to keep response times low. Our guide on how chatbots improve customer experience digs into this.

Frequently asked questions (FAQs)

What is NPS (Net Promoter Score)?

Net Promoter Score is a simple measure of customer loyalty. You ask one question, "How likely are you to recommend us to a friend or colleague?", on a 0 to 10 scale. Based on the answers, customers are grouped into promoters, passives, and detractors, and the score reflects the balance between your fans and your critics.

How is NPS calculated?

NPS is the percentage of promoters minus the percentage of detractors. Promoters score 9 to 10, passives score 7 to 8, and detractors score 0 to 6. The formula is NPS = % Promoters − % Detractors. Passives count toward your total responses but not directly in the score. The result ranges from −100 to +100.

What is a good NPS score?

Any score above 0 means you have more promoters than detractors, which is a positive sign. Broadly, above 30 is good, above 50 is excellent, and above 70 is world-class. Benchmarks vary a lot by industry, so it is most useful to track your own score over time and compare it to direct competitors.

Who counts as a promoter, passive, or detractor?

Promoters are customers who score 9 or 10. They are loyal and likely to refer others. Passives score 7 or 8: satisfied but unenthusiastic and easily tempted away. Detractors score 0 to 6: unhappy customers who can damage your brand through negative word of mouth.

Does NPS use a percentage or a raw count?

Either works because the formula uses percentages of your total responses. You can enter raw counts of promoters, passives, and detractors in the calculator above, and it converts them to percentages and computes the score for you.

How can I improve my NPS?

Close the loop with detractors quickly, remove friction from the experience, and respond faster. Slow or inconsistent support is one of the most common reasons customers slip from promoter to detractor, so speeding up responses (including with automation) often moves the needle.
