Formula used

  • Promoters are scores of 9–10.
  • Passives are scores of 7–8.
  • Detractors are scores of 0–6.

Percentages

%Promoters = (Promoters ÷ Total Responses) × 100
%Detractors = (Detractors ÷ Total Responses) × 100

Net Promoter Score

NPS = %Promoters − %Detractors

The score ranges from -100 to +100.

How to use this calculator

  1. Pick an input method: counts or raw scores.
  2. Enter values carefully, then select Calculate NPS.
  3. Review the NPS score, label, and category percentages.
  4. Use downloads to share results with stakeholders.
  5. Repeat with new data to compare periods and channels.

NPS as a decision metric

Net Promoter Score converts a 0–10 recommendation scale into a single value that ranges from -100 to +100. Because it is percentage based, NPS is comparable across teams, channels, and time windows, even when response volumes differ. Track NPS monthly or quarterly to identify direction, not just a one-time snapshot.

Response distribution matters

Two groups can share the same NPS while having very different distributions. For example, 55% promoters and 25% detractors yields an NPS of 30, but so does 35% promoters and 5% detractors with many passives. Use the promoter, passive, and detractor percentages shown above to understand the underlying customer mix and the specific movement needed to improve the score.

Benchmarks and practical ranges

Benchmarks vary by industry, geography, and survey design, so comparisons should use similar collection methods. In many service settings, an NPS around 0 indicates more promoters than detractors, while 30 suggests strong customer advocacy. Scores above 50 are often considered excellent, but the most useful benchmark is your own historical baseline and the rate of change after improvements.

Sample size and stability

Smaller samples produce more volatile scores. When responses are limited, focus on confidence and repeatability: compare like-for-like periods, avoid mixing major campaign effects, and watch rolling averages. Segment only when each segment has enough responses to be meaningful. Use the raw score mode to audit individual entries and spot data issues quickly.

Turning results into actions

Pair NPS with follow-up reasons and operational metrics. Detractors often highlight friction points, while promoters indicate what to protect and scale. Prioritize fixes that reduce detractors first, then invest in experiences that convert passives to promoters. Export CSV for analysis, and use the PDF summary for stakeholder reviews.

FAQs

1) What is a good Net Promoter Score?

A score above 0 is generally positive. Around 30 often indicates strong loyalty, and 50+ is commonly viewed as excellent. Always compare against your historical baseline and similar surveys.

2) Why are passives excluded from the NPS formula?

Passives neither strongly advocate nor strongly criticize. NPS focuses on the gap between promoters and detractors, while passives are still tracked as a key pool to convert through targeted improvements.

3) Can NPS be negative, and what does it mean?

Yes. A negative score means detractors outnumber promoters. It signals immediate experience issues, higher churn risk, and reputational drag. Use the category percentages to identify where changes are needed.

4) Should I use counts or raw scores?

Counts are fastest when you already have totals. Raw scores are useful for quick audits, small surveys, or exporting detailed breakdowns. Both methods produce the same NPS when the data matches.

5) How often should I measure NPS?

Monthly or quarterly is common. Choose a cadence that matches your product cycle and response volume. Consistent timing improves comparability and helps you detect real trend changes.

6) What is the best way to improve NPS?

Reduce detractors by fixing top friction points, then convert passives with reliability and proactive support. Validate improvements with repeated measurement, consistent sampling, and clear follow-up feedback questions.
