NPS Calculator
Calculate your Net Promoter Score, eNPS, or tNPS with instant visual results and industry benchmarks.
Measures customer loyalty by asking how likely they are to recommend your product or service on a 0-10 scale.
How to Use This NPS Calculator
This free NPS calculator helps you compute your Net Promoter Score in seconds. You can either paste raw survey scores (0-10 values) or enter the counts of promoters, passives, and detractors directly. The calculator supports three NPS variants:
- NPS (Net Promoter Score) — The standard customer loyalty metric used across industries to measure how likely customers are to recommend your product or service.
- eNPS (Employee Net Promoter Score) — Uses the same calculation to measure employee engagement and willingness to recommend your company as a workplace.
- tNPS (Transactional Net Promoter Score) — Measures satisfaction with a specific interaction such as a support call, purchase, or onboarding session.
Understanding Your NPS Results
Your NPS falls on a scale from -100 to +100. Here is how to interpret it:
- -100 to -1: Critical. More detractors than promoters — prioritize understanding what is driving dissatisfaction.
- 0 to 29: Needs improvement. You have room to grow. Focus on converting passives into promoters.
- 30 to 49: Good. You are performing well, but there is still opportunity to improve.
- 50 to 69: Great. Your customers are highly loyal — maintain what is working and address any remaining friction.
- 70 to 100: Excellent. World-class loyalty. Your customers are strong advocates for your brand.
Why NPS Matters for Product Teams
NPS is more than a vanity metric. It is a leading indicator of growth, retention, and word-of-mouth referrals. Product teams use NPS to prioritize features, identify at-risk customer segments, and measure the impact of changes over time. When paired with qualitative follow-up questions like "What is the primary reason for your score?", NPS becomes a powerful tool for driving product decisions.
For the best results, track your NPS over time rather than treating it as a one-time snapshot. Compare scores across customer segments, product lines, and time periods to identify trends and opportunities for improvement.
Going Beyond the Score
The number alone does not tell you why customers feel the way they do. Pair your NPS survey with an open-ended follow-up question and use a tool like Innerview to automatically analyze qualitative feedback at scale. Innerview helps you identify recurring themes, sentiment patterns, and actionable insights from hundreds of survey responses in minutes instead of days.
Frequently Asked Questions
What is a Net Promoter Score (NPS)?
Net Promoter Score is a customer loyalty metric that measures how likely your customers are to recommend your product or service. It is calculated by subtracting the percentage of detractors (scores 0-6) from the percentage of promoters (scores 9-10), resulting in a score between -100 and +100.
What is a good NPS score?
Any NPS above 0 means you have more promoters than detractors, which is a positive sign. An NPS of 30+ is generally considered good, 50+ is great, and 70+ is excellent. However, benchmarks vary significantly by industry — for example, the average NPS in SaaS is around 31, while Technology companies average around 57.
What is the difference between NPS, eNPS, and tNPS?
NPS (Net Promoter Score) measures customer loyalty toward your brand overall. eNPS (Employee Net Promoter Score) measures employee satisfaction and engagement using the same methodology but asking employees how likely they are to recommend the company as a workplace. tNPS (Transactional Net Promoter Score) captures feedback immediately after a specific interaction or transaction, such as a support call or purchase, to measure satisfaction with individual touchpoints.
How many survey responses do I need for a reliable NPS?
While there is no strict minimum, most researchers recommend at least 100 responses for a statistically meaningful NPS. With fewer responses, your score will have a wider margin of error. For transactional NPS (tNPS), aim for at least 50 responses per touchpoint. For ongoing tracking, collect responses continuously and compare scores over consistent time periods.
How is NPS calculated?
NPS is calculated using this formula: NPS = (% of Promoters) - (% of Detractors). Respondents who score 9-10 are Promoters, 7-8 are Passives, and 0-6 are Detractors. Passives are not directly used in the formula but they affect the percentages. For example, if 60% of your respondents are promoters and 20% are detractors, your NPS is 60 - 20 = 40.
