Net Promoter Score (NPS)

Net Promoter Score (NPS) measures customer loyalty by asking one question: how likely are customers to recommend your product or service to others, on a scale of 0 to 10.

Net Promoter Score = % Promoters - % Detractors

What is Net Promoter Score?

Net Promoter Score (NPS) is a measure of how willing your customers are to recommend your product or service to colleagues and friends.

It is based on a single survey question: "On a scale of 0 to 10, how likely is it that you would recommend [brand or product] to a friend or colleague?"

Responses fall into three groups:

• Promoters score 9 or 10: loyal enthusiasts who actively refer others
• Passives score 7 or 8: satisfied but not enthusiastic enough to advocate
• Detractors score 0 to 6: unhappy customers who can actively discourage others

NPS has become one of the most widely tracked customer metrics because it is simple to collect and connects directly to growth. When customers are willing to put their name behind your product, that trust drives referrals without additional spend. When they are not, it is a direct signal that something in the experience needs to change.

NPS is especially relevant for businesses growing through referrals or account expansion, what Eric Ries calls the "Viral Engine of Growth."

How to calculate Net Promoter Score

Subtract the percentage of Detractors from the percentage of Promoters. Passives are counted in the total but excluded from the formula.

NPS = (Promoters / Total Respondents × 100) - (Detractors / Total Respondents × 100)

Net Promoter Score example

Group	Count	Percentage
Promoters	55	44%
Passives	64	51.2%
Detractors	6	4.8%
Total	125	100%

NPS = 44% - 4.8% = 39.2

An NPS of 39.2 means your promoters significantly outnumber your detractors. That gap is what drives organic growth.

Here are two examples of NPS Klips used at Klipfolio to track this metric over time:

How does NPS compare to other customer satisfaction metrics?

NPS tells you whether customers would stake their reputation on recommending you. It does not tell you why a specific interaction fell short, or how hard it was for a customer to get help. That is where CSAT and CES come in.

Customer Satisfaction Score (CSAT)

Customer Satisfaction Score (CSAT) measures a customer's satisfaction with a specific interaction or transaction. A typical question: "How satisfied were you with your experience?" Customers respond on a scale, often 1 to 5 or 1 to 7.

CSAT is precise. It pinpoints which touchpoints are working and which are not, making it useful after a support call, a purchase, or a product onboarding. The limitation is that it reflects a moment, not a relationship. A customer can rate a single interaction highly while still being unlikely to recommend you overall.

To calculate CSAT, average the ratings across all responses for a given interaction, then convert to a percentage if needed.

Customer Effort Score (CES)

Customer Effort Score gauges how easy it was for a customer to get what they needed. A common question: "How easy was it to get the help you needed?" Responses run from "Very Difficult" to "Very Easy."

CES is particularly valuable for service-oriented businesses. High effort in a support interaction is one of the strongest predictors of churn. If customers have to work hard to get answers, they notice, even when the eventual outcome is positive.

Calculate CES by averaging the ease ratings across all responses for a given service interaction.

Using NPS, CSAT, and CES together

Each metric answers a different question. Used together, they give you a complete picture of the customer experience.

Start with NPS to understand the overall relationship. A low NPS signals that something broader needs to change. A high NPS confirms your strategy is working, but does not tell you where to keep investing.

Use CSAT to zoom in on specific interactions. Measure it across key touchpoints:

• After a purchase
• After a support interaction
• After onboarding a new feature

Use CES to identify friction. If customers find it hard to get help or navigate a process, that friction will eventually show up in your NPS, even if individual CSAT scores look fine.

When you read all three together, the gaps become actionable. A high NPS paired with low CES suggests customers love your product but find support frustrating. A high CSAT for a specific feature alongside a low NPS points to a broader issue undermining overall loyalty.

Net Promoter Score benchmarks

NPS varies significantly by industry. The Net Promoter Network provides the following averages as a reference point:

Highest scores:

• Department and specialty stores: 58
• Brokerage and investments: 45
• Tablet computers: 44
• Smartphones: 40

Lowest scores:

• Software and apps: 19
• Health insurance: 12
• Cable and satellite TV: 3
• Internet service: -3

For SaaS and software companies specifically, benchmarks from multiple sources suggest:

• The average NPS for software companies is around 23, based on NPS Benchmarks data showing scores ranging from 1 to 91, with most falling between 20 and 40
• Survey Monkey reports an average NPS of 31 across its own client base

The most useful benchmark is your own trend over time. A score of 30 that is climbing tells a better story than a score of 50 that is falling.

Factors that influence NPS

Understanding what moves your NPS is as important as tracking it. These are the factors with the most consistent impact.

Product quality and reliability

Customers who encounter recurring issues will not recommend you, regardless of how good the rest of the experience is. Consistent product quality is the foundation. Companies that treat quality assurance as ongoing work, not a one-time launch requirement, tend to see this reflected in their scores.

Customer service experience

A difficult support interaction can undo a strong product impression. Quick response times, knowledgeable staff, and genuine resolution of issues build the kind of trust that turns satisfied customers into active advocates. Investing in your support team is one of the most direct levers on NPS.

Perceived value

Customers who feel they are getting strong value for what they pay are far more likely to recommend you. Those who feel overcharged will detract. Pricing does not need to be the lowest in the market, but it needs to feel fair relative to the outcome delivered.

Brand reputation

A company's broader reputation shapes how customers feel before they even interact with your product. Negative press or public controversies can pull NPS down; consistent positive presence builds the goodwill that sustains it.

User experience

A product that is easy to use generates fewer frustrations and more confident recommendations. As digital touchpoints multiply, a seamless experience across all of them becomes a competitive advantage, not just a nice-to-have.

Communication and transparency

How often you communicate, and whether that communication is honest and relevant, affects customer trust. Customers who feel informed and heard are more likely to stay loyal. Personalized, timely communication reinforces the relationship.

External factors

Economic conditions, industry events, and competitor moves all affect customer sentiment in ways that are outside your direct control. Staying agile and keeping customers informed during disruption helps protect your score when conditions shift.

Competitor actions

When a competitor raises the bar on features, pricing, or service, it resets customer expectations. Regular competitive monitoring helps you anticipate those shifts rather than react to them after the damage shows up in your NPS.

Post-purchase experience

Onboarding, training, and ongoing support after the sale determine whether customers get the value they expected. A strong post-purchase experience is often the difference between a passive and a promoter.

Acting on feedback

Customers notice when their feedback leads to real changes. Closing the loop, letting customers know what you did with their input, builds the kind of trust that sustains loyalty over time.

Net Promoter Score challenges

Tracking NPS is straightforward. Getting reliable, actionable data from it is harder. These are the challenges most businesses encounter.

Reaching a broad customer base

Distributing a survey without feeling intrusive is a real balance to strike. Different customer segments respond to different channels: some prefer email, others respond to in-app prompts or SMS. Matching the delivery method to the segment improves response rates and makes the data more representative.

Be clear about why you are asking. Customers are more willing to give feedback when they understand it will be used to improve the product, not just to generate a marketing statistic.

Getting a meaningful response rate

A low response rate skews the data. If only your most frustrated or most enthusiastic customers respond, the score will not reflect your actual customer base.

Incentives, whether discounts, loyalty points, or exclusive content, can lift participation. A short, mobile-friendly survey with a clear call to action also helps. The easier the survey is to complete, the more responses you will get.

Acting on feedback in real time

Waiting for a quarterly report to surface a problem means the customer who flagged it has already moved on, often to a competitor. Integrating NPS tools with your CRM lets you flag and follow up on specific concerns immediately. AI-assisted analysis can surface patterns in open-ended responses faster than manual review.

Avoiding the vanity trap

A score without context is just a number. Many companies report NPS without connecting it to what changed or what to do next. The score matters less than the trend and the reasons behind it. Pairing NPS with metrics like Customer Referral Rate gives you a more complete picture of whether your customers are actually driving growth.

Net Promoter Score best practices

A well-run NPS programme gives you reliable data and a clear path to action. These practices make the difference between a score that sits in a report and one that drives decisions.

Set clear objectives before you survey

Know why you are asking and what you will do with the results. A clear objective shapes the survey design and ensures the data you collect is actually useful.

Segment your audience

Different customer groups have different experiences. Segmenting by industry, product tier, or tenure lets you spot patterns that a single aggregate score would hide. It also lets you tailor follow-up actions to the right group.

Use a consistent scale

Stick to the same 0-to-10 scale every time. Consistency makes your scores comparable across periods and meaningful as a trend.

Include open-ended questions

The score tells you where you stand. Open-ended questions tell you why. A single follow-up question, "What is the main reason for your score?", often surfaces the most actionable insight.

Close the loop with customers

Let customers know when their feedback led to a change. This is one of the most underused practices in NPS programmes. Customers who see their input reflected in the product become stronger advocates.

Re-survey at regular intervals

Customer sentiment shifts. Quarterly or annual re-surveys keep you current and let you track whether changes you made actually moved the score.

Integrate NPS with other metrics

NPS gives you the relationship-level view. Pair it with Customer Effort Score (CES) and Customer Satisfaction Score (CSAT) to understand the specific interactions behind the overall score. Together, these metrics give you the full picture of where the customer experience is strong and where it is not.

Make NPS visible across your team

NPS is not just a customer success metric. When product, support, sales, and leadership all see the same score and understand what drives it, the whole organization moves in the same direction.

How to monitor Net Promoter Score in real time

Checking your NPS once a quarter means you are always looking at the past. Real-time monitoring lets you catch problems early and act while they are still fixable.

Use dedicated NPS software

Platforms built for NPS collect responses, display scores, and surface trends automatically. Many integrate directly with your CRM, so feedback flows into the systems your team already uses. Look for tools that provide historical data alongside current scores, so you can see whether your score is improving or declining over time.

Set up automated alerts

Configure alerts for significant score shifts. If your NPS drops suddenly, you want to know immediately, not at the next scheduled review. Alerts can be set to trigger only when changes exceed a threshold you define, so you focus on what actually matters.

Track NPS on a dashboard

A dashboard puts your NPS alongside the other numbers that explain it: support ticket volume, churn rate, product usage, and referral activity. When everything is visible in one place, patterns emerge faster. You can see whether a dip in NPS coincides with a product release, a support backlog, or a pricing change, and act accordingly.

Connect NPS to your other systems

Integrating NPS data with your CRM or customer support platform gives you the full context behind each score. You can see which customer segments are driving your detractors, which campaigns correlate with promoter growth, and where the customer journey is breaking down.

Review your monitoring process regularly

The tools and methods you use to track NPS should evolve as your business does. Schedule regular reviews of your monitoring setup, not just the score itself, to make sure you are capturing the right data and acting on it efficiently.

Your compass to customer satisfaction

Net Promoter Score gives you a direct read on whether your customers trust you enough to put their name behind you. That trust is the foundation of referral-driven growth, and it is something no amount of paid acquisition can replace.

Track NPS consistently, pair it with CSAT and CES, and connect the score to the decisions it should be informing. A number sitting in a report does not help anyone. A score tied to a clear action, visible to the right people in real time, is what drives change.
