Net Promoter Score

—

Paste Net Promoter Score responses from 0 to 10. The calculator classifies detractors, passives and promoters, then shows the score and counts instantly.

## Responses fall into three groups

Scores 0–6 are detractors, 7–8 are passives and 9–10 are promoters.

## NPS ranges from −100 to 100

NPS is the percentage of promoters minus the percentage of detractors. Passives remain in the denominator.

## Frequently asked questions

Should I include blank responses?

No. Only valid answers from 0 through 10 belong in the calculation.

Is NPS a percentage?

It is reported as a score without a percent sign, although its inputs are percentages.
