Net Promoter Score measures how likely your customers are to recommend you on a scale from -100 to 100. The formula is simple: NPS equals the percentage of promoters minus the percentage of detractors. The calculator above runs that math the moment you type in your three response counts, so you get your score and the percentages behind it without any spreadsheet work.

How to calculate NPS

NPS comes from a single survey question: "How likely are you to recommend us to a friend or colleague?" answered on a 0 to 10 scale. You sort every response into three buckets, then run one subtraction.

  1. Promoters score 9 or 10. They are loyal fans who buy again and refer others. Count how many of your responses fall here.
  2. Passives score 7 or 8. They are satisfied but unenthusiastic, and a competitor could win them over. They do not count in the score itself.
  3. Detractors score 0 to 6. They are unhappy and can damage your brand through negative word of mouth.
  4. The formula. Work out the percentage of promoters and the percentage of detractors out of your total responses, then subtract: NPS = Promoter percent minus Detractor percent. With 120 promoters, 50 passives and 30 detractors, that is 60 percent minus 15 percent, for an NPS of 45.

What is a good NPS score?

Because the score runs from -100 to 100, the midpoint matters. Any score above 0 means you have more promoters than detractors, which is a healthy starting point. Above 30 is great, above 50 is excellent and above 70 puts you in world-class company. Below 0 means detractors outnumber promoters and you have a retention problem to fix.

Benchmarks shift by industry, so a score that looks average in one sector is strong in another. Software and consumer brands often post higher numbers than utilities or insurance. Compare yourself against direct competitors rather than a single universal figure, and watch your own trend over time, which tells you more than any one snapshot.

How to improve your NPS

The fastest route to a higher score is reducing detractors, not just adding promoters. Close the loop: follow up with every detractor, find out what went wrong and fix it, then look for the issues that show up again and again in their feedback. Solving the most common complaint usually moves the score more than any single feature you could ship.

Happy customers are also a growth channel that reaches well beyond the survey. Promoters leave the reviews and referrals that build trust, and those same signals increasingly feed search and AI answers.

FAQ

NPS Calculator: questions, answered

How do you calculate NPS?
Subtract the percentage of detractors from the percentage of promoters: NPS = Promoter percent minus Detractor percent. Promoters score 9 or 10, passives score 7 or 8, and detractors score 0 to 6. Passives are not subtracted, but they still count in the total, which lowers both percentages. The result is a whole number between -100 and 100.
What is a good NPS score?
Any score above 0 means you have more promoters than detractors, which is a healthy baseline. Above 30 is great, above 50 is excellent and above 70 is world-class. Scores vary by industry, so compare against companies in your own sector rather than a universal benchmark.
Why do passives not count toward NPS?
The NPS formula only subtracts detractors from promoters, so passives (scores of 7 and 8) are neither added nor subtracted. They still count in your total responses, though, which dilutes both the promoter and detractor percentages and pulls your score toward zero. A pile of passives quietly caps how high your NPS can climb.
What is the difference between promoters, passives and detractors?
Promoters rate you 9 or 10 and are loyal fans who refer others. Passives rate you 7 or 8 and are satisfied but easily tempted by competitors. Detractors rate you 0 to 6 and are unhappy customers who can harm your reputation through word of mouth and negative reviews.
How can I improve my NPS score?
Close the loop by following up with every detractor to understand and fix what went wrong, then tackle the issues that show up most often in their feedback. Nudge passives toward promoters by removing small friction points, and make it easy for promoters to leave reviews and refer friends. Most gains come from reducing detractors, not just adding promoters.
