Would your customer recommend you to a friend? The answer to this question directly determines your business’s growth potential. Net Promoter Score (NPS) turns this question into a single, measurable metric used by over 65% of Fortune 500 companies worldwide.
What Is NPS?
NPS was developed in 2003 by Fred Reichheld in collaboration with Bain & Company. The core question is simple:
“On a scale of 0-10, how likely are you to recommend this company to a friend or colleague?”
This single question measures something deeper than customer satisfaction: your customer’s willingness to actively advocate for your brand.
How to Calculate NPS
The calculation happens in three steps:
1. Segment Customers Into Three Groups
- Promoters (9-10): Loyal enthusiasts who actively recommend your brand. This group drives word-of-mouth growth.
- Passives (7-8): Satisfied but unenthusiastic customers. They can easily switch when a competitor makes an offer.
- Detractors (0-6): Unhappy customers who are likely to share negative experiences with their network.
2. Calculate the Percentages
Determine each group’s percentage of total respondents.
3. Apply the Formula
NPS = % Promoters - % Detractors
Example: Out of 200 customers, 120 are promoters (60%), 40 are passives (20%), and 40 are detractors (20%). NPS = 60 - 20 = +40.
NPS ranges from -100 to +100.
NPS Score Ranges: What’s Good and What’s Bad?
- -100 to 0: Serious customer dissatisfaction. Immediate improvement needed.
- 0 to 30: Average performance. Clear areas for improvement.
- 30 to 70: Good performance. Your customers are generally satisfied.
- 70 to 100: Excellent. Your customers are voluntary brand ambassadors.
According to Bain & Company data, the global average NPS varies between 20-60 depending on industry. Comparing against your own sector is more meaningful than looking at the absolute number.
NPS Benchmarks by Industry
To interpret your NPS correctly, you need to know industry averages:
- Retail and e-commerce: Average 40-55. Leaders like Amazon operate at 60+.
- Restaurants and F&B: Average 30-45. Lower in quick-service, higher in fine dining.
- Hospitality and lodging: Average 35-50. Boutique hotels generally outperform chain properties.
- Healthcare: Average 25-40. Patient experience investments directly impact scores.
- Financial services: Average 20-35. Digital banks are overtaking traditional institutions.
- Telecom: Average 10-25. The lowest NPS averages across all industries.
How to Improve Your NPS
Win Back Detractors
Reach out to detractors directly. According to Harvard Business Review research, 70% of customers whose complaints are resolved make repeat purchases. Fast intervention can convert a detractor into a promoter.
Activate Passive Customers
Passives are often overlooked, yet they carry the highest risk of switching to a competitor. Personalized offers and proactive communication can move this group into the promoter category.
Empower Promoters
Give your promoters referral programs and loyalty benefits. The cost of acquiring a new customer through a promoter is roughly 5x lower than traditional customer acquisition costs.
Make Structural Improvements
Collecting NPS data is not enough — you need to translate it into operational changes. Identify the most recurring detractor themes and conduct root cause analysis.
The Relationship Between Online Reviews and NPS
Here is the critical connection most businesses miss: Google, Yandex, and Apple Maps reviews are a natural reflection of your NPS.
Customers who leave 5-star reviews are very likely your promoters. Those who leave 1-2 star reviews are your detractors. From this perspective, online reviews function as a continuous, free NPS survey.
Research shows a 0.7-0.8 correlation between NPS and online review ratings. This means you can reliably estimate your NPS by analyzing your review data.
Using Review Data as an NPS Proxy
- 5 stars = Promoter (9-10)
- 4 stars = Passive (7-8)
- 1-3 stars = Detractor (0-6)
With this mapping, you can calculate an approximate NPS from your review data without sending a single survey.
Track NPS Over Time
A single NPS measurement is just a snapshot. The real value lies in tracking the NPS trend:
- Monthly measurements help filter out seasonal effects.
- Post-campaign measurements gauge the impact of customer experience initiatives.
- Location-level comparisons reveal which branches are improving and which are declining.
- Competitive benchmarking helps you continuously assess your position in the market.
According to Bain & Company’s 11-year longitudinal study, companies that consistently improve their NPS grow at twice the rate of their industry average.
