What Is Net Promoter Score (NPS)?

Net Promoter Score measures customer loyalty by asking one question: "How likely are you to recommend us to a friend or colleague?" on a 0–10 scale. Respondents are grouped into Promoters (9–10), Passives (7–8), and Detractors (0–6). The formula is simple: NPS = (% Promoters − % Detractors) × 100. Scores range from −100 to +100.

What Is Customer Satisfaction Score (CSAT)?

CSAT measures how satisfied customers are with a specific interaction, product, or service. It is typically calculated as the percentage of respondents who selected a "satisfied" or "very satisfied" response. CSAT = (Satisfied responses ÷ Total responses) × 100.

What Is Customer Effort Score (CES)?

Customer Effort Score measures how easy it was for a customer to accomplish a task — like resolving a support ticket or completing a purchase. Respondents rate effort on a 1–7 scale where 1 is "very difficult" and 7 is "very easy." CES is the average of all responses. Lower friction correlates strongly with higher retention.

How to Improve Your Scores

Improving NPS

Focus on turning Passives into Promoters by following up after surveys, closing the feedback loop, and investing in product improvements that address recurring complaints. Even a small reduction in Detractors can swing your score significantly.

Improving CSAT

Speed and resolution matter most. Set clear response-time SLAs, empower agents to solve problems without escalation, and measure CSAT per channel so you can identify weak spots. Satisfied customers are 5× more likely to repurchase.

Improving CES

Reduce the number of steps required to get help. Self-service knowledge bases, proactive messaging, and omnichannel support all lower effort. Research from the Harvard Business Review shows that reducing effort is a stronger predictor of loyalty than delighting customers.

Frequently asked questions

How is NPS calculated?

NPS = ((Promoters − Detractors) ÷ Total responses) × 100. Promoters are respondents who scored 9–10, Passives scored 7–8, and Detractors scored 0–6. The result ranges from −100 to +100.

What is a good NPS score?

Any score above 0 is considered good because it means you have more Promoters than Detractors. Scores above 30 are great, and scores above 70 are world-class. The average NPS for SaaS companies is around 30–40.

How is CSAT calculated?

CSAT = (Number of satisfied responses ÷ Total responses) × 100. "Satisfied" typically means respondents who selected the top one or two options on your rating scale (e.g., 4–5 on a 5-point scale).

What is a good CSAT score?

A CSAT score above 75% is generally considered good. Top-performing companies often achieve 80–90%. The benchmark varies by industry — e-commerce averages around 80%, while telecom averages closer to 65%.

How is CES calculated?

CES is the arithmetic mean of all effort scores. Respondents rate their effort on a 1–7 scale (1 = very difficult, 7 = very easy). A higher average means lower friction for customers.

What is a good CES score?

On a 1–7 scale, a CES of 5 or above is considered good. Scores below 4 suggest customers are finding it too difficult to interact with your service and you should investigate friction points.

What is margin of error in NPS?

Margin of error tells you how much your NPS might differ from the true population score due to sample size. It uses a 95% confidence interval. With 100 responses, the margin of error is roughly ±10 points. With 1,000 responses, it drops to about ±3 points.

How often should I measure NPS, CSAT, and CES?

NPS is typically measured quarterly or biannually to track overall loyalty trends. CSAT is best measured immediately after specific interactions (e.g., after a support ticket is resolved). CES should be measured right after a customer completes a task you want to optimize.

Can I use NPS, CSAT, and CES together?

Yes — they measure different things and complement each other well. NPS captures overall loyalty, CSAT measures satisfaction with specific interactions, and CES gauges how easy it is to do business with you. Together, they give a complete picture of customer experience.
