NPS asks “How likely are you to recommend us to a friend or colleague?” Scores above 0 are good, above 50 excellent, though benchmarks vary widely by industry.

Inputs explained
| Field | What to enter |
|---|---|
| Promoters (9–10) | A number |
| Passives (7–8) | A number |
| Detractors (0–6) | A number |
What each result means
- Total responses = [Promoters (9–10)] + [Passives (7–8)] + [Detractors (0–6)]
- Promoters = [Promoters (9–10)]÷[Total responses]×100
- Detractors = [Detractors (0–6)]÷[Total responses]×100
- Net Promoter Score = ([Promoters (9–10)] – [Detractors (0–6)])÷[Total responses]×100
Example values
How the main result changes when Promoters changes and everything else stays at the example values above:

|---|---|
| 60 | 13 |
| 90 | 26 |
| 120 | 36 |
| 150 | 44 |
| 180 | 50 |
| 240 | 59 |
Formula
NPS = % promoters (scores 9–10) − % detractors (scores 0–6)Passives (7–8) count in the total but not in the scoreRange: −100 to +100Worked example
Inputs — Promoters (9–10): 120; Passives (7–8): 60; Detractors (0–6): 40.
Results — Total responses = 220; Promoters = 54.55 %; Detractors = 18.18 %; Net Promoter Score = 36; Rating = Good (0–49).
