As businesses continue to prioritize delivering exceptional customer experiences, they often rely on metrics to measure customer satisfaction. While there are various metrics available, two of the most popular ones are Net Promoter Score (NPS) and Customer Satisfaction (CSAT). Despite their similarities in measuring customer satisfaction, NPS and CSAT actually focus on distinct aspects of the customer experience.

I was having a conversation about them when I realized I was talking about CSAT while using the NPS term. The idea of this blog came right away since it’s important for businesses to understand the differences between NPS and CSAT to determine which metric best suits their needs.

While NPS provides insight into overall customer loyalty and advocacy, CSAT is useful in identifying specific areas for improvement in the customer experience. By utilizing both metrics, businesses can gain a more comprehensive understanding of customer satisfaction and make data-driven decisions to enhance their customer experience.

Net Promoter Score (NPS)

NPS is a metric used to measure customer loyalty and the likelihood of customers recommending a business to others. It is calculated based on customers’ responses to a single question: “On a scale of 0–10, how likely are you to recommend our product/service to a friend or colleague?” Customers who respond with a score of 9 or 10 are considered Promoters, those who respond with a score of 7 or 8 are considered Passives, and those who respond with a score of 0–6 are considered Detractors. The NPS is then calculated by subtracting the percentage of Detractors from the percentage of Promoters, resulting in a score between -100 and 100.

NPS provides businesses with an overall measure of customer loyalty and likelihood to recommend, which can help them identify areas for improvement and measure the effectiveness of their customer experience initiatives. A higher NPS score generally indicates that a business has a higher number of loyal customers who are more likely to recommend the business to others.

There are primarily three types of NPS:

  • Transactional NPS: This type of NPS is based on a single transaction or interaction between a customer and a business. It asks customers to rate their experience on a scale of 0–10 and then asks them why they gave that rating.
  • Relationship NPS: This type of NPS measures the overall relationship between a customer and a business over a period of time. It typically asks customers how likely they are to recommend the business to others on a scale of 0–10 and why.
  • Employee NPS: This type of NPS measures the loyalty of employees towards their employer. It asks employees to rate how likely they are to recommend their employer as a place to work on a scale of 0–10 and why. It can help businesses understand the satisfaction level of their employees and take steps to improve it.

Customer Satisfaction Score (CSAT)

CSAT is a metric used to measure customer satisfaction with a specific interaction or experience with a business. It is usually calculated by asking customers to rate their satisfaction with a specific question such as “How satisfied were you with your recent purchase/interaction?” on a scale of 1–5 or 1–10.

CSAT provides businesses with insights into the satisfaction of their customers with a specific interaction or experience, which can help them identify areas for improvement and measure the effectiveness of their customer service initiatives. A higher CSAT score generally indicates that a business is doing a better job of meeting the needs and expectations of its customers.

Key Differences Between NPS and CSAT

While both NPS and CSAT measure customer satisfaction, there are key differences between the two metrics.

What They Measure

NPS measures overall customer loyalty and likelihood to recommend a business, while CSAT measures customer satisfaction with a specific interaction or experience with a business.

What They Indicate

A higher NPS score generally indicates that a business has a higher number of loyal customers who are more likely to recommend the business to others. A higher CSAT score generally indicates that a business is doing a better job of meeting the needs and expectations of its customers with a specific interaction or experience.

In summary:

NPS and CSAT are both customer satisfaction metrics used by businesses to measure customer satisfaction, but they are different in their approach and what they measure.

NPS is calculated by subtracting the percentage of Detractors from the percentage of Promoters, resulting in a score between -100 and 100. CSAT is usually calculated by asking customers to rate their satisfaction on a scale of 1–5 or 1–10.

By understanding the differences between NPS and CSAT, businesses can choose the right metric(s) to measure customer satisfaction and make data-driven decisions to improve the customer experience.
