What is how to calculate nps?
Understanding how to calculate nps is fundamental for any business aiming to foster customer loyalty. The Net Promoter Score (NPS) is a widely recognized metric used to measure customer satisfaction and the likelihood of customers recommending a product or service to others.
Businesses of all sizes, from startups to Fortune 500 companies, use this metric because of its simplicity and correlation with long-term growth. It classifies customers into three distinct categories based on their response to a single question: "On a scale of 0 to 10, how likely are you to recommend us to a friend or colleague?"
One common misconception is that NPS is a percentage. While the components are percentages, the final score is an integer ranging from -100 to +100. Learning how to calculate nps helps you bypass simple averages that can hide significant dissatisfaction within your customer base.
how to calculate nps Formula and Mathematical Explanation
The math behind how to calculate nps is straightforward but powerful. It focuses on the extremes of your customer sentiment while ignoring the "middle ground" of passives.
The Formula:
NPS = (% Promoters) – (% Detractors)
Step-by-Step Derivation:
- Step 1: Count the number of Promoters (those who answered 9 or 10).
- Step 2: Count the number of Detractors (those who answered 0 through 6).
- Step 3: Calculate the percentage of Promoters by dividing the count by total responses and multiplying by 100.
- Step 4: Calculate the percentage of Detractors in the same way.
- Step 5: Subtract the Detractor percentage from the Promoter percentage.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Promoters | Respondents scoring 9-10 | Count | 0 to Total |
| Passives | Respondents scoring 7-8 | Count | 0 to Total |
| Detractors | Respondents scoring 0-6 | Count | 0 to Total |
| NPS | Net Promoter Score | Integer | -100 to 100 |
