ネットプロモータースコア（NPS）計算ツール

Q: What is a good NPS for a SaaS company?

Above 50 is excellent. 30-50 is good. 0-30 is average. Below 0 is concerning. The average B2B SaaS NPS is 30-40 according to Satmetrix/Bain benchmarks.

Q: How is NPS different from customer satisfaction (CSAT)?

NPS measures willingness to recommend (loyalty + growth). CSAT measures satisfaction with a specific interaction. NPS is more predictive of long-term growth; CSAT is better for transactional feedback.

Q: How often should I survey NPS?

Quarterly is standard for B2B SaaS. Some companies use transaction-based NPS after key events (onboarding, support resolution). Annual surveys miss too much.

Q: What response rate do I need for reliable NPS?

Aim for 30%+ response rate for statistical significance. Lower response rates may have response bias (unhappy customers are more likely to respond).

Q: How does NPS correlate with growth?

Companies with NPS 50+ grow at 2x+ the rate of companies with NPS below 20. Promoters drive referrals (lower CAC), renew at higher rates, and expand faster.

Q: Should I benchmark NPS by industry?

Yes. SaaS NPS averages 30-40. E-commerce averages 50-60. Insurance averages 20-30. Always compare against your specific industry and segment.

Q: How do I improve NPS?

Close the loop with detractors, fix product pain points, improve onboarding, enhance support quality, and build features that drive customer outcomes. Track NPS driver analysis with tools like [Intercom](https://intercom.com) for proactive customer communication and feedback collection.

Q: Can NPS be manipulated?

Yes. Survey timing, question phrasing, and incentive structure can bias results. Use consistent methodology and benchmark against industry standards for accuracy.

アンケート回答からネットプロモータースコアを計算 — 顧客ロイヤルティを測定し、成長を予測します。

Net Promoter Score (NPS) is the gold standard for measuring customer loyalty and predicting business growth. Based on a single question - 'How likely are you to recommend us to a friend?' - NPS categorizes respondents into Promoters (9-10), Passives (7-8), and Detractors (0-6). The score ranges from -100 to +100. Companies with high NPS grow faster because Promoters drive word-of-mouth referrals and have lower churn. This calculator helps you compute your NPS from survey raw data and understand your customer loyalty profile.

この計算機の使い方

Enter the number of Promoters (scores 9-10), Passives (scores 7-8), and Detractors (scores 0-6) from your latest NPS survey.
The calculator will compute your overall NPS, total responses, and the percentage breakdown of each category..

計算式と具体例

NPS = (Promoters ÷ Total Responses × 100) - (Detractors ÷ Total Responses × 100):

Example: 200 Promoters, 150 Passives, 50 Detractors.

Total = 400.

Promoter % = 50%.

Detractor % = 12.5%.

NPS = 50% - 12.5% = 37.5.
