The formula

How the NPS calculator works.

NPS is the percentage of promoters minus the percentage of detractors. Promoters score 9 or 10, detractors score 0 to 6 and passives, who score 7 or 8, count in the total but not the score.

The result runs from minus 100 to 100. A positive number means promoters outnumber detractors. The passives drag the denominator without helping the score, which is why a wall of 7s and 8s quietly holds your NPS down.

What it means

What your net promoter score actually tells you.

NPS is a useful trend line and a terrible single source of truth. It tells you sentiment is moving, not why. Benchmarks vary wildly by industry, so your own trend over quarters beats any number you borrowed from a blog.

The real value is in the follow-up question. Why did you give that score. That is where the insight to act on lives, not in the headline figure.

Common questions

What people ask about the NPS calculator.

How is NPS calculated?+

Subtract the percentage of detractors, who score 0 to 6, from the percentage of promoters, who score 9 or 10. Passives count in the total but not the score.

What is a good NPS?+

It varies hugely by industry, so your own trend over time matters more than any benchmark. Above zero means promoters outnumber detractors.

Why do passives lower my NPS?+

Passives count in the total response base but add nothing to the score, so a lot of 7s and 8s dilute the percentage of promoters.

Is NPS enough on its own?+

No. Pair it with the written comments and with usage and retention data. The score is a headline, the reasons behind it are the story.
