Question 1

What is Net Promoter Score (NPS) and how does it correlate with customer retention, organic growth, and enterprise value?

Accepted Answer

Net Promoter Score (NPS) is a customer loyalty and relationship metric based on the question: "On a scale of 0-10, how likely are you to recommend our product/company to a colleague or friend?" By segmenting respondents into Promoters (9-10), Passives (7-8), and Detractors (0-6), NPS provides a quantifiable leading indicator of customer churn, word-of-mouth referral velocity, and customer lifetime expansion.

Question 2

What is the exact mathematical formula for NPS and its statistical margin of error?

Accepted Answer

Net Promoter Score is calculated as: NPS = % Promoters - % Detractors = ((Promoters - Detractors) / Total Respondents) × 100. NPS ranges from -100 (all detractors) to +100 (all promoters). Standard Error (SE) = 100 × sqrt([p(1-p) + d(1-d) + 2pd] / Total Respondents), where p is promoter fraction and d is detractor fraction.

Question 3

How does NPS compare to CSAT (Customer Satisfaction) and CES (Customer Effort Score)?

Accepted Answer

CSAT measures short-term satisfaction with a specific transactional touchpoint (e.g. customer support ticket resolution). CES evaluates the operational ease of completing a specific action. NPS evaluates overarching brand loyalty, strategic partnership health, and long-term customer retention probability.

Question 4

What is a worked step-by-step example calculating NPS from raw survey responses?

Accepted Answer

A company surveys 500 customers and receives: 320 Promoters (scores 9-10), 110 Passives (scores 7-8), and 70 Detractors (scores 0-6): % Promoters = (320 / 500) × 100 = 64.0%. % Detractors = (70 / 500) × 100 = 14.0%. NPS = 64.0% - 14.0% = +50.0. The 110 Passives (22.0%) are excluded from the net calculation but contribute to total sample volume.

Question 5

What are institutional NPS benchmark tiers across B2B SaaS, E-Commerce, and Financial Services?

Accepted Answer

An NPS > 0 is considered positive, NPS > +30 is strong, and NPS > +50 is world-class. Industry medians typically reflect: B2B SaaS +35 to +45; Consumer Tech/E-commerce +45 to +60; Retail Banking +30 to +35; and Telecommunications/Cable +0 to +15.

Question 6

What biases (survey non-response bias, cultural calibration differences, transactional vs relationship survey timing) distort NPS?

Accepted Answer

Non-response bias frequently distorts NPS when dissatisfied customers churn silently without taking surveys. Furthermore, cultural grading variations (e.g. European respondents traditionally score more conservatively than US respondents) require regional cohort normalization, and relational surveys should be separated from post-incident transactional surveys.

Question 7

Are customer survey responses, email lists, or satisfaction scores transmitted to external servers?

Accepted Answer

No. All survey distributions, promoter breakdowns, and statistical confidence intervals are computed locally within your browser with zero remote logging.
