What Is NPS?
The Net Promoter Score (NPS) is a widely used metric for measuring customer loyalty and overall sentiment. It’s based on one simple but powerful question:
- Customers respond on a scale from 0 to 10, where 0 means not at all likely, and 10 means extremely likely.
- Based on these responses, customers are grouped into promoters, passives, and detractors.
- The final NPS, which ranges from –100 to 100, gives you a clear snapshot of how customers feel about your service and how likely they are to advocate for your brand.
How to Calculate Your Net Promoter Score
Calculating your Net Promoter Score (NPS) is simple and helps you understand how loyal your customers really are
- To calculate your NPS, use the standard Net Promoter Score formula:
- Percentage of Promoters – Percentage of Detractors = NPS
- Promoters are customers who give you a score of 9 or 10, while detractors are customers who respond with a score between 0 and 6.
- Example:
- If 60% of your customers are promoters and 10% are detractors, your NPS score would be:
- 60 - 10 = 50
- Using an online NPS calculator helps you apply the NPS formula accurately and quickly, without manual calculations.

How to Interpret the NPS scale
Your Net Promoter Score (NPS) helps you understand how customers truly feel after interacting with your product or support team. Based on their responses, customers fall into three simple groups.
Promoters (score 9 or 10)
Promoters are your happiest customers, loyal fans, and potential advocates. Encourage them to leave reviews and, share experiences on social media, or reward them with special offers to strengthen their loyalty.
Passives (score 7 or 8)
These customers are neutral. They don’t actively promote or criticize your brand and are excluded from the NPS calculation. However, with the right engagement, they can be converted into promoters.
Detractors (score 0 to 6)
These are dissatisfied customers who are unlikely to recommend your brand. They may leave negative reviews or, speak ill of your brand to others, and are at high risk of churn. Address their concerns promptly to prevent further damage.
What Is a Good Net Promoter Score?
A good Net Promoter Score (NPS) depends on your industry, customer base, and growth goals. However, general NPS benchmarks from leading platforms suggest:
Below 0: Concerning
More detractors than promoters; signals customer dissatisfaction and weak customer loyalty.
Exactly 0: Neutral
Equal promoters and detractors; customer sentiment is balanced but fragile.
Above 0: Positive
You have more promoters than detractors, indicating improving customer satisfaction.
Above 30: Strong
Indicates solid customer satisfaction and consistent customer loyalty.
Above 50: Excellent
Reflects a highly loyal customer base and strong Net Promoter Score performance.
Above 70: World-class
Typically achieved by top‑performing brands with exceptional customer experience.
Ultimately, a good NPS is one that improves over time. Track it consistently, act on feedback, and let it guide your customer experience strategy.
Types of NPS Surveys
Net Promoter Score surveys come in two main types, each serving a unique purpose in customer experience analysis:
1. Transactional NPS (tNPS)
Triggered after a specific interaction or event, like a support ticket resolution, product purchase, or onboarding. It helps measure satisfaction with a particular experience and identify immediate service gaps.
2. Relational NPS (rNPS)
Sent at regular intervals (monthly, quarterly, or annually) to gauge overall customer loyalty and brand perception. It's best for tracking long-term trends and benchmarking performance over time.
