Net Promoter Score (NPS) is a customer loyalty metric that measures how likely your customers are to recommend your brand to a friend or colleague. It's based on a single survey question: "On a scale of 0–10, how likely are you to recommend [Brand] to a friend?" Respondents are classified as Promoters (9–10), Passives (7–8), or Detractors (0–6). NPS is widely used because it correlates strongly with customer retention, word-of-mouth growth, and long-term revenue — customers who actively recommend your brand are also the ones most likely to keep buying.
NPS = % Promoters − % Detractors
Passives are excluded from the calculation. NPS ranges from −100 to +100.
Example: If you survey 200 customers and 90 are Promoters (45%), 60 are Passives (30%), and 50 are Detractors (25%):
NPS = 45% − 25% = +20
NPS benchmarks vary by industry. For ecommerce and consumer goods, an NPS of 40+ is considered excellent. Most Indian D2C brands in their growth phase target NPS of 30–50. Any positive NPS means you have more brand advocates than detractors, which is a good starting point.
NPS is a leading indicator of organic growth. High NPS brands grow significantly through referrals and word-of-mouth — two acquisition channels that cost a fraction of paid advertising. When Mamaearth or mCaffeine grew rapidly, a substantial portion of their new customers came from recommendations by existing users who had genuinely good experiences. For D2C brands trying to reduce CAC, building a high-NPS customer base is a long-term strategy that pays dividends for years. NPS also identifies your most at-risk customers (Detractors) before they churn and leave negative reviews. Addressing Detractors directly — through proactive outreach and problem resolution — can convert them to Passives or even Promoters, preventing brand damage and recovering potential repeat purchases.
Kapiva introduced a post-purchase NPS survey sent via WhatsApp 7 days after delivery (when customers had time to use the product). Their initial NPS was +22. After analyzing Detractor responses, they found the most common complaint was that the product description claimed "results in 2 weeks" but many customers didn't feel a difference in that time. Kapiva updated product pages to set realistic timelines ("most customers see results in 4–6 weeks with consistent use"), added a usage tips WhatsApp sequence, and introduced a 30-day satisfaction guarantee. Six months later, NPS rose to +47. More importantly, repeat purchase rate increased by 31%, validating that NPS improvement translates directly to retention metrics.
NPS is a lagging metric — it takes weeks or months for experience changes to show up in NPS scores. However, NPS surveys generate qualitative insight (the open-ended "Why did you give that score?" responses) that is invaluable for generating A/B test hypotheses. Recurring Detractor themes about confusing checkout, unclear product information, or poor mobile experience directly inform which pages to test first.
