How to use it

  1. Enter counts for promoters, passives, and detractors, and optionally select an industry benchmark. NPS is promoter percent minus detractor percent, so the mix matters as much as the final score.
  2. Read total responses, NPS score, promoter, passive, and detractor percentages, classification, benchmark delta, and trend guidance. This tool classifies 70 and above as Excellent, 30-69 as Good, 0-29 as Needs Improvement and below 0 as Poor; compare with your own industry's benchmark rather than a universal scale.
  3. Interpret the score with the mix. A decent NPS with a large passive block means onboarding and product education may unlock upside, while high detractor share signals immediate churn and reputation risk even if the overall score is not catastrophic.
  4. Use the guidance to pick the next action for the next 30 days: detractor recovery, passive-to-promoter conversion, or referral capture. If you are below industry benchmark by 5 points or more, start with root-cause interviews before spending harder on acquisition.
  5. Re-run monthly or quarterly using the same survey method. Track NPS and detractor percent together because a flat score can still hide worsening service risk if promoter gains merely offset growing dissatisfaction.

Questions people usually ask

How is NPS calculated?

NPS = % Promoters (scores 9-10) minus % Detractors (scores 0-6). Passives (7-8) count toward the total but do not directly add or subtract from the score.

What is a good NPS score?

This calculator rates +70 and above Excellent, +30 to +69 Good, 0 to +29 Needs improvement, and below 0 Poor. That is one common operating convention; others are gentler and treat any positive score as good. Industry context matters: in Retently's 2026 benchmark, industry averages run from 26 for internet software and services to 68 for financial services and consulting, and the calculator can compare you with any of them.

Why does this tool ask for industry?

Industry averages differ widely. In Retently's 2026 NPS Benchmark, averages run from 26 for Internet Software & Services to 68 for Financial Services and Consulting, and B2B Software & SaaS averages 41. Comparing with your own industry avoids false confidence from a one-size-fits-all threshold.

How often should I track NPS?

Monthly or quarterly works for most teams. Consistent cadence matters more than high frequency, because trends are more useful than one-off snapshots.
