When comparing various scoring systems to the traditional NPS (Net Promoter Score) 10-point scale, the scores can be aligned as follows:
Comparison to NPS 10-Point Scale:
1 on a 1-5 scale = 2 on a 0-10 scale
2 on a 1-5 scale = 4 on a 0-10 scale
3 on a 1-5 scale = 7 on a 0-10 scale
4 on a 1-7 scale = 9 on a 0-10 scale
5 on a 1-5 scale = 10 on a 0-10 scale
Similarly, when using alternatives like emojis or a 5-star system, the values get converted accordingly. For instance, if a user selects 3/5 emojis, this might translate to around 7 on the 0-10 NPS scale.
3 Scale Emoji Display Type:
Sad → 1 (Detractor)
Neutral → 7 (Neutral)
Happy → 10 (Promoter)
NPS Calculation Formula:
Promoters: Scores of 9-10
Passives/Neutrals: Scores of 7-8
Detractors: Scores of 1-6
Note on Accuracy:
While converting scores from alternative scales to the NPS 10-point scale can be helpful, the granularity and interpretation may vary, so accuracy may decrease when switching systems.
