Net Promoter Score (NPS)
Net Promoter Score is a customer loyalty metric derived from asking respondents how likely they are to recommend a company's product or service on a zero-to-ten scale, with promoters (9-10) minus detractors (0-6) giving the NPS, used by Indian consumer, fintech, and telecom companies to proxy long-term customer retention quality.
NPS was developed as a simplified alternative to complex customer satisfaction surveys. The methodology asks a single question: 'On a scale of 0 to 10, how likely are you to recommend us to a friend or colleague?' Respondents scoring 9 or 10 are classified as promoters, those scoring 7 or 8 are passives, and those scoring 0 to 6 are detractors. The NPS equals the percentage of promoters minus the percentage of detractors, yielding a score that can range from -100 to +100.
In India, NPS gained prominence as digital financial services, e-commerce, and telecom companies sought to measure customer experience quality in a fast-growing but intensely competitive market. Bajaj Finance, one of India's largest non-banking finance companies, regularly cited its NPS as evidence of the stickiness of its customer base and the quality of its consumer lending experience. High NPS was used to argue that customer acquisition cost would be partially offset by referral-driven organic growth.
For digital platforms and fintech companies, NPS serves an additional purpose: it is a leading indicator of churn. A declining NPS often precedes rising churn rate because detractors are the customers most likely to lapse or switch to a competitor. Companies that track NPS longitudinally can identify specific touchpoints — onboarding friction, service failure, billing disputes — that are driving customers into the detractor category and intervene before those customers leave.
In Indian banking, private sector banks including HDFC Bank and Kotak Mahindra Bank have used NPS in internal performance evaluations for branch and service staff. The banking regulator's increasing focus on customer grievance redressal has made NPS-adjacent metrics more visible, as high complaint volumes from detractors can attract supervisory attention.
The limitations of NPS are well-documented. It is a single-question survey that does not diagnose why customers are satisfied or dissatisfied. Cultural differences in response scales mean that Indian consumers may systematically score differently from Western consumers for the same underlying experience. Companies that self-administer NPS surveys also face selection bias if only satisfied customers complete them. Despite these caveats, when measured consistently over time within a company, NPS trends provide useful directional signals about whether the customer experience is improving or deteriorating.
