How to Use This Calculator

Input the percentage of Promoters, Passives, and Detractors from your survey data.
Make sure the total equals 100% to maintain valid results.
You may use decimal values for greater precision (e.g., 33.33%).

Converting Counts to Percentages

percentage = (count / total_responses) × 100

Important Considerations

Interpret NPS over time, not in isolation.
Review qualitative feedback to supplement the score.
Compare results across segments for deeper insights.

Edge Cases Explained

100% Promoters: NPS = +100 (Ideal but rare, often due to bias or sampling error).
100% Detractors: NPS = -100 (Critical issue requiring immediate action).
50/50 Split: NPS = 0 (Even sentiment, polarized customers).
1/3 Each: NPS = 33.3 − 33.3 = 0 (Neutral, needs context).
100% Passives: NPS = 0 (No loyalty or advocacy detected).

NPS Predictor Description

What Is NPS?

The Net Promoter Score (NPS) is a powerful metric used to evaluate customer loyalty and satisfaction based on a simple question:

'On a scale from 0 to 10, how likely are you to recommend our company/product/service to a friend or colleague?'

Respondent Categories

Promoters (9–10): Loyal customers likely to promote your brand.
Passives (7–8): Satisfied but indifferent; vulnerable to competitors.
Detractors (0–6): Unhappy customers who may share negative experiences.

Formula for NPS

NPS = %Promoters − %Detractors

Note: Passives are not counted in the NPS calculation but are tracked for contextual insight.

Pro Tip: Use NPS trends over time, not just single values, to track customer sentiment momentum.

How to Use the NPS Predictor

To calculate your NPS, enter the percentage values for Promoters, Passives, and Detractors. These must add up to 100%.

Step-by-Step:

Collect customer feedback scores (0–10).
Categorize responses into Promoters, Passives, and Detractors.
Calculate each group’s percentage based on total responses.
Apply the NPS formula.

Promoters: 300 (15%)
Passives: 900 (45%)
Detractors: 800 (40%)
NPS = 15 − 40 = −25

Frequently Asked Questions
