Net Promoter Score (NPS) has become one of the most widely used indicators of customer experience (Customer Experience, CX) over the past decade. Its popularity is based on simplicity — a single question that measures a customer’s willingness to recommend a brand. However, this very simplicity often leads to underestimating its true value.
Research published in Springer (Keiningham et al.) shows that an increase in NPS by 10 points may be associated with up to a 10% revenue growth. However, it is not a mechanical equation. NPS is not a lever that can simply be turned. It is an indicator — and only the way an organization works with it determines its economic impact.
Why NPS has a direct relationship with revenue
Customer experience today has a demonstrable impact on companies’ financial performance. According to a McKinsey study (2020), companies that systematically manage CX achieve 20–30% higher customer satisfaction and at the same time increase the likelihood of repeat purchase.
NPS captures this relationship in three key dimensions:
Retention (customer retention) – Bain & Company has long shown that increasing retention by 5% can lead to profit growth of 25–95% (Reichheld, 2001). Promoters (customers giving 9–10) have a significantly higher likelihood of returning.
Share of Wallet – satisfied customers spend more. A study by Temkin Group (now Qualtrics XM Institute) shows that loyal customers generate up to 5× higher lifetime value (Customer Lifetime Value, CLV).
Acquisition through recommendations – word-of-mouth remains one of the most trusted sources. Nielsen (2021) states that 88% of customers trust recommendations from acquaintances more than any other form of marketing.
In other words: higher NPS means more promoters, fewer detractors — and therefore lower acquisition costs, higher retention, and higher average customer value.
Czech context: NPS as a management tool, not a report
In the Czech market, NPS is gradually shifting from the role of a “reporting metric” to the role of a management tool. Companies such as Alza, Packeta, dm drogerie, Škoda Auto, or banking institutions like Raiffeisenbank work with NPS at the level of specific touchpoints (customer interactions), not only as an aggregated number.
The key shift lies in three areas:
1. Transactional NPS (tNPS) – measurement immediately after interaction (e.g. delivery, contact with support) makes it possible to identify a specific problem, not just a general feeling.
2. Connection with operations – NPS is not a marketing KPI, but a tool for managing processes across the company.
3. Closed feedback loop (closed loop) – companies actively contact dissatisfied customers and resolve their problem in real time.
Without these steps, NPS remains only a number without impact.
Where value breaks: from measurement to action
Measuring NPS alone creates no value. The decisive factor is the organization’s ability to translate feedback into concrete changes.
This is where tools like InsightSofa come into play, shifting work with NPS from passive data collection to active experience management.
1. Immediate feedback collection
Delayed data has limited value. Real-time feedback makes it possible to identify a problem at the moment it arises — often even before the customer leaves for a competitor.
2. Identification of weak points
Segmentation by touchpoints, products, or customer segments reveals exactly where dissatisfaction arises. This is a fundamental difference compared to traditional satisfaction surveys.
3. Prioritization of changes according to impact on NPS
Not all problems have the same weight. Advanced analytics makes it possible to identify factors that have the greatest impact on NPS — and thus on revenue.
4. Employee involvement (Employee Experience, EX)
Customer experience is directly dependent on employee experience. According to Gallup (2023), teams with high engagement have 23% higher profitability. Sharing feedback and working with it at the team level increases their motivation and responsibility.
The most common mistake: chasing the number
Companies often make the mistake of trying to “increase NPS” instead of improving the experience. The result is tactics such as:
- selective outreach to satisfied customers,
- motivating customers toward higher ratings,
- pressure on employees to “improve the score.”
These approaches may improve the number in the short term, but in the long term they undermine trust — both inside the company and among customers.
NPS as a strategic compass
NPS only makes sense when it becomes part of decision-making. Not as a KPI on a dashboard, but as an input into the management of:
- product innovations,
- customer processes,
- team performance.
As both practice and research show, the link between NPS and financial performance exists. However, it is not automatic. Companies that are able to leverage it have one thing in common: they treat customer experience as a systemic discipline, not as a project.
And that is precisely the real difference between companies that measure NPS — and those that build growth on it.
