Use Cases

Measure Customer Loyalty

Use NPS to gauge overall customer satisfaction and loyalty. A high score indicates strong advocacy, while a low score signals areas for improvement.

Example: A SaaS company surveys 500 users and finds 200 promoters, 100 detractors, and 200 passives. NPS = (200/500 - 100/500) * 100 = 20.

Track Changes Over Time

Regularly calculate NPS to monitor the impact of product changes, customer service improvements, or marketing campaigns on customer sentiment.

Example: After launching a new feature, you survey again and see NPS rise from 20 to 35, indicating positive reception.

Frequently Asked Questions

What is Net Promoter Score (NPS)?
NPS is a customer loyalty metric that measures how likely customers are to recommend your product or service. It's calculated by subtracting the percentage of detractors from the percentage of promoters, yielding a score between -100 and 100.
How do I calculate NPS using this calculator?
Enter the number of promoters (responses 9-10), detractors (responses 0-6), and total responses. The calculator computes the percentage of promoters and detractors, then subtracts detractors from promoters to give your NPS.
What is a good NPS score?
A positive NPS (above 0) is generally good, above 50 is excellent, and above 70 is world-class. However, benchmarks vary by industry, so compare your score to competitors in your sector.

Tips & Common Mistakes

Tips

  • Ensure your total responses include all survey answers, including passives (7-8), to get an accurate NPS.
  • Use a consistent survey scale (0-10) and question wording to compare NPS across different periods.
  • Segment your NPS by customer type (e.g., new vs. long-term) to uncover insights.
  • Follow up with detractors to understand their concerns and improve your score.

Common Mistakes to Avoid

  • Forgetting to include passives in total responses, which skews the percentage calculations.
  • Using a different scale (e.g., 1-5) without adjusting the promoter/detractor thresholds.
  • Comparing NPS across different industries without considering benchmarks.
