What is NPS (Net Promoter Score)?

NPS (Net Promoter Score) is a popular metric that measures a customer's likelihood to recommend your brand or product to others, expressing customer loyalty and satisfaction in a single score. It answers questions like "Is customer experience good?", "What's the loyalty level?", "Do we have growth potential?" providing a quick pulse check. This is why it's particularly common in SaaS, e-commerce, mobile apps, and service industries.

What Does NPS (Net Promoter Score) Mean?

At the core of NPS is a single question:

"On a scale of 0–10, how likely are you to recommend this product/brand to a friend or colleague?"

Based on their scores, customers fall into 3 groups:

Promoter (9–10): Brand advocates. Loyal, likely to repurchase and recommend.
Passive (7–8): Satisfied but weak loyalty. Easily switches to competitors.
Detractor (0–6): Dissatisfied. Risk of negative reviews, returns/cancellations, and churn.

How is NPS Calculated?

The NPS score is calculated using this formula:

NPS = (% Promoter) − (% Detractor)

The Passive group (7–8) is not included in the calculation, but it affects the overall distribution.

NPS Calculation Example

Let's say from 100 people:

55 gave 9–10 (Promoter) → 55%
25 gave 7–8 (Passive) → 25%
20 gave 0–6 (Detractor) → 20%

NPS = 55 − 20 = 35

Result: NPS score is 35

What Should Your NPS Score Be?

NPS varies by industry and market dynamics. However, here's a practical interpretation framework:

-100 to 0: Alarm. Detractors outnumber Promoters.
0 to 30: Average. Product works but plenty of room for improvement.
30 to 50: Good. Strong satisfaction and loyalty signals.
50+: Excellent. High word-of-mouth growth potential.
70+: Rare and exceptional level.

The best comparison is with your own historical trend and industry benchmarks.

Why is NPS Important?

There are several reasons why NPS is so popular:

1) It Simply Measures Customer Loyalty

Instead of complex surveys, a single question approximates "do customers love us?"

2) It Signals Growth Potential

As the Promoter percentage increases, the likelihood of organic growth through referrals increases.

3) It Indicates Churn Risk Early (Especially in SaaS)

If Detractor percentage is rising, cancellation/churn risk may also be rising.

4) It Provides a Roadmap for Product and Operational Improvement

NPS alone doesn't explain "why"; but with the right follow-up question, you can uncover root causes.

How to Create an NPS Survey?

For effective NPS implementation, two steps are recommended:

1) The Main NPS Question

"On a scale of 0–10, how likely are you to recommend us?"

2) Follow-up Question (The Critical Part)

"What's the main reason for this score?"

These open-ended responses are the gold that turns NPS into action.

You can also add a third question:

"What should we do to improve your experience?"
"What feature or topic frustrated you the most?"

When and To Whom Should NPS Be Asked?

Timing in NPS dramatically affects the score. Common strategies:

After onboarding (SaaS): When users start seeing value (e.g., 7–14 days).
After first purchase (E-commerce): After product delivery and use (e.g., 7 days).
After support ticket closes: Support NPS / CSAT can be measured together.
Regular periods: Monthly/quarterly "relationship NPS".

Segmentation Suggestion

New user vs. power user
Free vs. premium
High churn risk cohort
Country / channel / plan basis

NPS Disadvantages and Important Considerations

NPS is powerful but isn't sufficient on its own:

It doesn't explain the "why": Open-ended responses are required for the question "why is it low?"
Cultural differences exist: In some countries, giving 9–10 is less common.
It's open to manipulation: Questions like "would you give us a 10?" skew the score.
Sample bias may exist: Only very happy or very unhappy users may respond.

This is why it's usually good to monitor NPS alongside these metrics:

CSAT (Customer Satisfaction)
CES (Customer Effort Score)
Churn / Retention
Cohort analysis
Support ticket themes

How to Improve NPS?

Practical approaches to increase NPS:

Address Detractors quickly: The biggest score impact comes from here.
Solve top 3 complaint themes: Tag open responses (bugs, pricing, support, UX, etc.).
Improve onboarding: Users should reach the "aha moment" quickly.
Standardize support quality: First response time + resolution time make a huge difference.
Turn Promoters into growth: Referral programs, review requests, case study offers.

Frequently Asked Questions

How many questions should NPS have?

Minimum 1 question (NPS) + ideally 1 open-ended follow-up.

Why aren't Passives included in the calculation?

NPS treats Passives as neutral to clearly separate loyalty extremes (supporters vs. critics).

Is NPS the same as customer satisfaction?

Similar but not the same. NPS measures more loyalty/recommendation intent, CSAT measures more immediate satisfaction.

Conclusion: Using NPS Correctly

NPS (Net Promoter Score) is a score measuring customer loyalty based on the likelihood of recommending you. NPS = Promoter % − Detractor % is the formula. The most accurate use is not monitoring the score alone; gathering reasons through follow-up questions and converting them into product/operational actions.
