Defining Net Promoter® Score

In a normal customer satisfaction survey, you might ask customers for specific feedback on the products and services you provide to determine customer service satisfaction. Questions like: "How satisfied were you with our product prices?"

While this question and others can be benefical, these questions might not provide you with all of the detail you need to improve your business.

Why? Because people who are satisfied might still leave. They might appreciate your products, price, or service, but other companies may do these things better. In other words, they may like you, but they may like others more.

The Net Promoter® Score Bain & company developed in 2003 is designed to ask something a lot different. Instead of asking if your customers are satisfied, you're asking your customers if they're promoters of your company. You're trying to determine if your customers are willing to speak up and recommend your brand. This is vital if you wish to expand your business, as positive reviews and feelings toward your company can really promote growth.

This question will provide you with one number that will show you just how many of your customers are truly company advocates. Our Net Promoter Score® (NPS) Calculator below, will help you to understand calculation, and how you can apply the number to better your organization.

History of the Net Promoter® Score Question

in 2003, Fred Reichheld and a Bain & Company launched a research project to determine whether a different approach than the standard customer satisfaction survey would yeild better restuls. Working with data supplied by Satmetrix, they tested a variety of questions to see how well the answers correlated with company performance and customer behavior.

As it turned out, one question worked best, and thus the NPS question was born.
