Net Promoter Score Calculator (NPS) by TheCalcTools
How the Net Promoter Score Calculator (NPS) works
NPS asks ‘How likely are you to recommend us?’ on a 0 to 10 scale. NPS = % promoters − % detractors, so it ranges from −100 to +100. Passives count in the total but not in the score.
Benchmarks vary a lot by industry. Track the trend over time and read the comments behind the scores.
The formula
NPS = (promoters − detractors) ÷ responses × 100
Worked example
Using the default values shown in the calculator:
| Promoters (scored 9 or 10) | 220 |
|---|---|
| Passives (scored 7 or 8) | 130 |
| Detractors (scored 0 to 6) | 50 |
- 220 promoters, 130 passives and 50 detractors out of 400: NPS = 42.5.
Result:
| Net Promoter Score | 42.5 |
|---|---|
| Promoters | 55.0% |
| Passives | 32.5% |
| Detractors | 12.5% |
| Responses | 400 |
