NPS (Net Promoter Score)
What is Net Promoter Score (NPS)?
Net Promoter Score (NPS) is a customer loyalty metric that measures how likely customers are to recommend a company, product, or service to others. It is based on a simple question: “On a scale of 0–10, how likely are you to recommend us to a friend or colleague?”
Customers are grouped into three categories:
- Promoters (9–10): Loyal enthusiasts who recommend the brand
- Passives (7–8): Satisfied but not highly engaged
- Detractors (0–6): Unhappy customers who may discourage others
NPS is calculated by subtracting the percentage of Detractors from the percentage of Promoters. Scores range from -100 to +100.
Why does NPS matter?
- Provides quick insight into customer satisfaction and loyalty
- Identifies happy customers and dissatisfied customers
- Predicts future growth through referrals and retention
- Highlights areas needing improvement
- Allows benchmarking over time and against competitors
How does NPS work?
- Ask customers the NPS question using surveys or feedback tools
- Categorize responses into Promoters, Passives, and Detractors
- Calculate score: % Promoters − % Detractors
- Analyze feedback through follow-up questions
- Take action to improve customer experience
