If you’re looking to measure customer satisfaction and loyalty, one metric that stands out is the Net Promoter Score (NPS). NPS is a popular and straightforward tool that helps businesses gauge their customers’ satisfaction with products or services. In this article, we’ll show you how to calculate the NPS score step by step.

What is NPS?

Net Promoter Score is a management tool developed by Fred Reichheld, Bain & Company and Satmetrix to evaluate customer loyalty. The measurement derived from a single question: “On a scale of 0 to 10, how likely are you to recommend [company/product/service] to your friends, family, or colleagues?” Based on the responses, customers are classified into three categories: promoters, passives, and detractors.

Calculating NPS

The calculation of NPS is relatively simple and follows these steps:

1. Survey your customers

Send a survey to your customers asking them the question mentioned above. Ensure that the question is clear and that the scale provided ranges from 0 (Not at all likely) to 10 (Extremely likely).

2. Segregate responses based on customer categories

Categorize the respondents according to their scores as follows:

– Promoters: customers who rated their likelihood of recommending your product or service between 9 and 10. These are happy customers who are likely to promote your company.

– Passives: those who rated their likelihood between 7 and 8. These customers are satisfied but might not promote your company actively since they could also be swayed by competitive offers.

– Detractors: respondents who rated their likelihood between 0 and 6. These are unhappy customers who might not only avoid recommending your product or service but could even discourage others from using it.

3. Calculate category percentages

Calculate the percentage for each category (promoters, passives, and detractors) using the total number of respondents as the denominator. For example, if you have 200 responses with 120 promoters, the percentage for promoters would be (120 / 200) × 100 = 60%.

4. Compute NPS score

Subtract the percentage of detractors from the percentage of promoters to get your Net Promoter Score. Using our example: 60% (promoters) – 20% (detractors) = 40%. Your NPS score is 40.

NPS scores range from -100 (when all customers are detractors) to +100 (when all customers are promoters). A positive NPS suggests that your company has a loyal customer base and a good overall reputation.

Regularly calculating your NPS score allows you to track performance, pinpoint issues, and evaluate initiatives aimed at improving customer satisfaction. By understanding your customers’ experiences and addressing their needs, your company will be better equipped to maintain a high level of customer satisfaction and loyalty.
