Net Promoter Score:
The Ultimate Guide

Master the world's most powerful customer loyalty metric. This comprehensive guide covers everything from basic calculations to advanced optimization strategies.

What is Net Promoter Score?

Net Promoter Score (NPS) is the world's leading customer loyalty metric, created by Fred Reichheld and Bain & Company in 2003. It measures customer satisfaction through a single question: "How likely are you to recommend our company to a friend or colleague?"

Why NPS Matters

  • Simple: One question that anyone can understand
  • Predictive: Correlates strongly with business growth
  • Actionable: Provides clear direction for improvement
  • Comparable: Enables benchmarking across industries

How NPS Works

NPS uses a 0-10 rating scale to segment customers into three categories:

😍

Promoters (9-10)

Loyal enthusiasts who will keep buying and refer others, fueling growth.

😐

Passives (7-8)

Satisfied but unenthusiastic customers vulnerable to competitive offerings.

😠

Detractors (0-6)

Unhappy customers who can damage your brand through negative word-of-mouth.

How to Calculate NPS

The NPS calculation is straightforward but powerful:

The NPS Formula

NPS = % Promoters - % Detractors

NPS scores range from -100 to +100. A positive score means more customers recommend you than don't.
