Why it matters

See the distribution behind the score.

Net Promoter Score compresses three response groups into one number, which makes reporting convenient but can hide important differences in the underlying audience. Two surveys may produce the same score even when one contains many promoters and detractors while the other is dominated by passive respondents.

Those distributions imply different customer experiences and may require different follow-up work. Reviewing the share of every group helps teams avoid treating the headline score as a complete diagnosis and encourages them to connect the result with comments, support themes and behavioral evidence.

A transparent calculation makes the score easier to explain, reproduce and compare responsibly.
