NPS vs CSAT:
Which Metric Should You Track?

What Is Net Promoter Score (NPS)?

Net Promoter Score is a loyalty metric that measures how likely your customers are to recommend your product or service to others. Introduced by Fred Reichheld in 2003, NPS has become one of the most widely adopted customer experience benchmarks across industries.

The NPS question is straightforward: "On a scale of 0 to 10, how likely are you to recommend [company/product] to a friend or colleague?"

Based on their response, customers fall into three groups:

Your NPS is calculated by subtracting the percentage of Detractors from the percentage of Promoters. The result is a score between -100 and +100. A positive score means you have more promoters than detractors, and a score above 50 is considered excellent.

What Is Customer Satisfaction Score (CSAT)?

Customer Satisfaction Score measures how satisfied customers are with a specific interaction, product, or experience. Unlike NPS, which gauges overall loyalty, CSAT captures satisfaction at a particular moment in time.

The typical CSAT question looks like this: "How satisfied were you with [experience/product/interaction]?" Customers rate their satisfaction on a scale, commonly 1 to 5 or 1 to 7.

CSAT is calculated as the percentage of respondents who selected the top satisfaction ratings (typically 4 and 5 on a 5-point scale). For example, if 80 out of 100 respondents chose 4 or 5, your CSAT score is 80%.

Scales vary by industry. Some organizations use a 1-to-5 star rating, others prefer a 1-to-7 Likert scale, and some keep it simple with a 1-to-3 smiley-face system. Regardless of the scale, the core concept remains the same: measuring satisfaction with a specific touchpoint.

NPS vs CSAT: Side-by-Side Comparison

When to Use NPS

NPS is best suited for measuring the big picture of your customer relationship. Consider using it when:

• Tracking brand health over time -- Run quarterly NPS surveys to spot loyalty trends and measure the impact of strategic changes.
• Predicting churn -- Detractors are significantly more likely to cancel. NPS helps you identify at-risk accounts before they leave.
• Benchmarking against competitors -- NPS is an industry-standard metric, making it easy to compare your performance with published benchmarks in your sector.
• Measuring the impact of major initiatives -- Launched a new product line or overhauled your service? NPS before and after reveals whether your investment moved the needle on customer loyalty.
• Board and executive reporting -- NPS is a single number that executives understand instantly, making it ideal for leadership dashboards and investor updates.

When to Use CSAT

CSAT excels at measuring satisfaction with specific interactions and touchpoints. It is the right choice when:

• Evaluating support quality -- Send a CSAT survey after every support ticket resolution to monitor agent performance and identify training needs.
• Post-purchase feedback -- Measure satisfaction immediately after a purchase or checkout experience to catch friction points early.
• Onboarding assessment -- Gauge how new users feel about your setup process, documentation, and first-run experience.
• Feature-level feedback -- After a user interacts with a new feature, a quick CSAT question tells you whether it meets expectations.
• Event and training evaluations -- Collect attendee satisfaction immediately after webinars, workshops, or training sessions while the experience is fresh.

Using NPS and CSAT Together

NPS and CSAT are not competing metrics. They answer different questions and work best when used in tandem. NPS tells you whether your overall relationship is healthy. CSAT tells you whether individual interactions are meeting expectations. A customer can be satisfied with a single support call (high CSAT) yet still unlikely to recommend you (low NPS) because of broader issues with pricing, reliability, or product fit.

Here is how to combine them effectively:

Frequently Asked Questions

Key Takeaways

• NPS measures loyalty; CSAT measures satisfaction. They answer fundamentally different questions about your customer experience.
• Use NPS for the big picture. It is ideal for quarterly tracking, churn prediction, and executive reporting.
