About this tool

The Net Promoter Score (NPS) is the world’s most widely used metric for measuring customer loyalty. Based on a single question — “How likely are you to recommend us to a friend or colleague?” — NPS converts customer sentiment into a clear number between -100 and +100. Our free NPS calculator turns your raw survey responses into an actionable score in seconds, with no formulas, no spreadsheets, and no waiting.

To calculate NPS, respondents are grouped into three categories: Promoters (rated 9–10), who actively recommend your brand; Passives (rated 7–8), who are satisfied but unenthusiastic; and Detractors (rated 0–6), who could harm your reputation. The formula is simple: NPS = % Promoters − % Detractors. A positive score means more advocates than critics, and a score above 50 puts you in elite company.

Whether you’re a startup measuring product-market fit, a customer success team tracking post-onboarding sentiment, or an enterprise monitoring loyalty across hundreds of touchpoints, this free NPS calculator gives you the insight you need — instantly.

Quick answer

NPS (Net Promoter Score) is calculated by subtracting the percentage of Detractors (survey respondents who rate 0–6) from the percentage of Promoters (those who rate 9–10). Passives (7–8) are excluded. The result is a number between -100 and +100. A score above 0 is positive, above 20 is good, and above 50 is considered excellent.

NPS Calculator — FAQ

What is a good NPS score?+
A good NPS score depends on your industry. As a general benchmark: 0–20 is acceptable, 20–50 is good, 50–70 is excellent, and above 70 is world-class. B2B SaaS companies typically aim for 30–50; retail and hospitality brands often see 20–40. Always benchmark against your own historical trend and your industry average — relative improvement matters as much as absolute score.
How is NPS calculated?+
NPS is calculated by subtracting the percentage of Detractors (respondents who scored 0–6) from the percentage of Promoters (respondents who scored 9–10). Passives (7–8) are excluded from the formula. The result is a whole number between -100 and +100. Example: if 60% of respondents are Promoters and 15% are Detractors, your NPS = 60 − 15 = 45.
How many responses do I need for a reliable NPS?+
For statistically reliable NPS, aim for at least 200–400 responses. Fewer than 50 responses can produce misleading scores because a single outlier shifts the result significantly. If your response count is low, treat the score as directional — useful for spotting trends, but not for high-stakes decisions. Use our Sample Size Calculator to determine the right number of respondents before you survey.
What’s the difference between NPS and CSAT?+
NPS measures overall loyalty and likelihood to recommend — it captures the long-term relationship between a customer and your brand. CSAT measures satisfaction with a specific interaction or transaction. NPS is better for tracking brand health over time; CSAT is better for evaluating individual touchpoints like support tickets, purchases, or onboarding sessions. Most customer-centric teams use both metrics together.
Can I use this calculator for employee NPS (eNPS)?+
Yes. The NPS formula works identically for employee surveys. Simply ask employees: “How likely are you to recommend this company as a place to work?” on a 0–10 scale, then enter the results into the calculator. eNPS scores typically run lower than customer NPS — a score above 10 is generally considered good for most organizations.
