Satisfaction & NPS Calculator

What is NPS (Net Promoter Score)?

NPS (Net Promoter Score) is a customer loyalty metric introduced by Fred Reichheld of Bain & Company in 2003. It asks "How likely are you to recommend our product/service to a friend or colleague?" using a 0-10 scale, categorizing customers into Promoters (9-10), Passives (7-8), and Detractors (0-6), ultimately calculating a score between -100 and +100.

NPS Score Interpretation (Result Range: -100 to +100)

Note: NPS collects scores on a 0-10 scale, but the final result is a score between -100 and +100 (Promoter % minus Detractor %).

• Excellent (NPS ≥ +70): World-class performance, like Apple, Tesla and other top brands
• Good (NPS +30 to +69): Strong performance with room for improvement
• Needs Improvement (NPS 0 to +29): Below-average customer satisfaction, requires active improvement
• Poor (NPS < 0): Critical warning, detractors outnumber promoters
