Last updated: 2026-10-25

> The NPS calculator works out your Net Promoter Score from survey responses – the percentage of promoters (9–10) minus the percentage of detractors (0–6) – from counts in each group or the full 0–10 distribution.

## Inputs

- Promoters (9–10)
- Passives (7–8)
- Detractors (0–6)

## Results

- Total responses
- Promoters
- Detractors
- Net Promoter Score
- Rating

## Formula

```
NPS = % promoters (scores 9–10) − % detractors (scores 0–6)
Passives (7–8) count in the total but not in the score
Range: −100 to +100
```

## Explanation

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.

### How to use the NPS Calculator

- **Promoters (9–10)**

- Exchange rates and prices change constantly – update them before you rely on a result.
- Use results as estimates and confirm important figures with the official source.
- Everything runs in your browser – try different values to compare scenarios.

### Common mistakes to avoid

- Mixing gross and net figures.
- Using outdated rates.
- Treating rules of thumb as exact.

### 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:
