Everything you need to know about the NPS formula!

Have you ever wondered what your customers really think about your product or service? Sure, you can track reviews, monitor complaints, and conduct surveys, but how do you capture the essence of their loyalty and satisfaction? This is where the Net Promoter Score or the NPS formula comes into play.

The NPS formula is a simple yet powerful tool used to measure customer loyalty. It’s based on a single, straightforward question: “How likely are you to recommend our product/service to a friend or colleague?” The answers can reveal a lot more than just satisfaction — they can highlight whether your customers are your biggest advocates or warning signs of churn.

In this blog, we’ll walk you through how to calculate NPS using the NPS formula, interpret the results, and ultimately use the NPS formula to drive better business decisions. But first, let’s dig into what exactly NPS is and why it’s become a go-to metric for businesses around the world.

What is the Net Promoter Score (NPS)?

Let’s start by answering the basic question: What is Net Promoter Score?

In simple terms, the Net Promoter Score (NPS) is a customer loyalty metric that gauges how likely your customers are to recommend your product or service to others. It’s a quick snapshot of how you’re doing in the eyes of your customers.

The idea of NPS was developed by Fred Reichheld in 2003 to simplify the way companies measure and act on customer feedback. He wanted to create a metric that was easy to calculate and even easier to understand, so he came up with the NPS formula.

Think of NPS like a health check-up for your business — if your score is high, you’re on the right track; if it’s low, it’s time to address some underlying issues. Imagine asking your customers this question: “On a scale of 0–10, how likely are you to recommend our product/service to a friend or colleague?”

Here’s how responses are categorized:

  • Promoters (9–10): These are your loyal fans. They not only love your product but also act as brand ambassadors, spreading the word and driving referrals.
  • Passives (7–8): They’re satisfied, but not enthusiastic. They’re at risk of being swayed by your competitors.
  • Detractors (0–6): Unhappy customers who are likely to share negative experiences, hurting your brand’s reputation.

When you apply the NPS formula (we’ll get to that soon!), you get a score that tells you how many customers fall into each group. It’s an indicator of whether your customers are happy enough to stay — and even more importantly — recommend your business to others.

By understanding NPS, you can gauge the strength of your customer relationships and pinpoint areas for improvement, making it a cornerstone of customer success strategies.

How is it NPS Calculated: The NPS Formula

Now that we know what Net Promoter Score is, it’s time to break down the numbers. So, how exactly is NPS calculated using the NPS formula? The good news: it’s super simple! You don’t need to be a math whiz or have a fancy calculator — just a basic understanding of percentages.

Here’s the NPS formula:

But what does that mean in practice? Let’s walk through an example.

Example:

Imagine you sent out a survey to 100 customers. Here’s how they responded:

  • 60 customers gave you a score of 9 or 10 (Promoters)
  • 25 customers gave you a score of 7 or 8 (Passives)
  • 15 customers gave you a score of 0 to 6 (Detractors)

Now, let’s plug these numbers into our NPS formula:

  • Promoters: 60%
  • Detractors: 15%
  • Passives aren’t considered in the NPS formula.

So, your NPS would be:

NPS = 60 − 15 = 45

A score of 45 is pretty good! It means you have a strong base of happy customers, but there’s still room for improvement.

Remember, your NPS can range from -100 (every respondent is a Detractor) to +100 (every respondent is a Promoter). A positive score means you have more promoters than detractors, while a negative score indicates the opposite. The higher the score, the stronger your customer loyalty!

Pro Tip: Always pair your NPS score with the qualitative feedback you receive from customers. It’ll help you understand why your detractors aren’t happy and what your promoters love about your product.

Measuring NPS: A Step-by-Step Guide

Now that you know how the NPS formula works, it’s time to look at how you can measure NPS in real life using the NPS formula. Follow these simple steps to get an accurate read on your customers’ loyalty and satisfaction:

Step 1: Designing the NPS Survey

Crafting the perfect NPS survey starts with a single question:
“On a scale of 0–10, how likely are you to recommend our product/service to a friend or colleague?”
This question helps segment your customers into Promoters, Passives, and Detractors. Make sure to keep it clear, simple, and specific to your business.

💡 Pro Tip: Consider adding an open-ended follow-up question like, “Can you tell us why you chose this score?” This will give you qualitative insights to complement the number you got using the NPS formula.

Step 2: Choosing the Right Time and Channel

Timing is everything! Deploy your NPS survey at critical touchpoints, such as:

  • Post-purchase (to measure product satisfaction)
  • After customer support interactions (to evaluate service quality)
  • Quarterly or Annually (to track overall brand perception)

You can use channels like email, in-app messages, or even SMS — just make sure it’s a format your customers are comfortable with.

Step 3: Collecting Responses

Encourage maximum participation by keeping your in-app survey short and to the point. Personalize the message, and if possible, offer a small incentive (like a discount or freebie) to boost customer engagement.

Example: “We value your opinion! Take just 30 seconds to tell us what you think, and enjoy 10% off your next purchase as a thank you.”

Step 4: Analyzing the Data

Once the responses start rolling in, it’s time to calculate your NPS using the NPS formula we discussed earlier. Break down your results by segment (e.g., by geography or customer type) to gain deeper insights.

  • Are there more promoters in a particular region?
  • Are certain product lines generating more detractors?

Step 5: Taking Action Based on NPS Insights

A good NPS survey doesn’t end at calculating the score — it’s just the beginning! Use the feedback to improve your product, service, and customer experience. For example:

  • If you have a lot of Detractors, consider addressing their common pain points.
  • If you have many Passives, think about strategies to turn them into Promoters (like exclusive offers or improved features).

💡 Remember: Measuring NPS using the NPS formula isn’t a one-time thing. Make it a continuous process, and watch how your score — and customer satisfaction — evolve over time!

What does your NPS really mean?

So, you’ve run your survey, crunched the numbers, and arrived at your Net Promoter Score. But what does that score tell you?

Understanding the NPS Score Range

Your NPS score can range from -100 to +100. But what’s considered a good score? Here’s a quick breakdown:

  • NPS > 50: 🎉 Amazing! Your customers love you! A score above 50 indicates strong customer loyalty and advocacy.
  • NPS between 0 and 50: 😊 Doing Well. Your customers are generally satisfied, but there’s room to create more enthusiastic promoters.
  • NPS < 0: 😟 Needs Attention. This is a red flag. It means you have more unhappy customers (detractors) than happy ones. It’s time to dive deeper and address their concerns.

Industry Benchmarks: What’s a ‘GOOD’ NPS?

NPS can vary significantly by industry. For instance:

  • Retail: An NPS above 60 is considered great.
  • Healthcare: A score above 30 is considered good.
  • Tech & Software: Scores in the 40–60 range are common.

So, before celebrating or panicking over your NPS, benchmark it against your industry standards. A 30 in healthcare might be a win, but the same score in retail could indicate issues.

Interpreting NPS Beyond the Numbers

NPS is not just a number — it’s a conversation starter. Use it to understand why your customers feel the way they do. For example:

  • A high NPS could mean you have great customer support, a unique product, or a solid brand reputation. Dig into what’s working and double down on it!
  • A low NPS might point to gaps in product quality, service delays, or unmet expectations. Use follow-up questions and qualitative feedback to identify the root causes.

A Real-World Example

Let’s say you run a SaaS business and have an NPS of 20. While it’s positive, it’s not stellar. Upon closer inspection, you realize that your detractors often cite “complex onboarding” as a pain point. That’s your signal to streamline the customer onboarding process. Once you make the changes, run another NPS survey in a few months. If your score improves, you know you’re on the right track!

Bottom line: Use your NPS as a compass, not just a score. It’s a tool that guides your decisions and helps turn customer feedback into actionable insights.

Wrapping Up: Why NPS Should Be Your Go-To Metric

Net Promoter Score isn’t just a number you calculate once and forget. It’s a pulse check on your business’s health and a guiding light for shaping your customer experience strategy. From identifying loyal fans to spotting pain points, the NPS formula gives you a clear picture of where you stand with your customers — and where you need to improve.

Remember, NPS is more than just a score; it’s a conversation starter and a springboard for action. So, keep the dialogue open, listen to what your customers are really saying, and let NPS be the compass that guides your business to new heights!
