NPS Net Promoter Score Calculator

Understanding Net Promoter Score (NPS)

The Net Promoter Score (NPS) is a widely used market research metric that measures customer loyalty, satisfaction, and likelihood to recommend a company's product, service, or brand. First introduced by Fred Reichheld of Bain & Company in 2003, it is typically derived from a single-question survey: "On a scale of 0 to 10, how likely are you to recommend us to a friend or colleague?"

Respondent Classifications

Respondents are segmented into three distinct groups based on their rating:

• Promoters (Scores 9-10): Loyal and enthusiastic customers who will continue buying and refer others, fueling organic business growth.
• Passives (Scores 7-8): Satisfied but indifferent customers who are vulnerable to competitive offerings and unlikely to actively promote your brand.
• Detractors (Scores 0-6): Unhappy customers who are unlikely to buy from you again and can damage your reputation through negative word-of-mouth.

How to Calculate Net Promoter Score

To calculate your Net Promoter Score, subtract the percentage of Detractors from the percentage of Promoters. Passives are included in the total response count but do not directly influence the final score.

NPS = % Promoters - % Detractors

The resulting score is expressed as a whole number between -100 (if every respondent is a Detractor) and +100 (if every respondent is a Promoter).

Interpreting NPS Benchmarks

NPS benchmarks vary by industry, but general rules of thumb apply:

• Below 0: Poor. Indicates the business has more unhappy customers than loyal promoters. Immediate action is needed.
• 0 to 30: Good. A solid starting point, indicating a healthy customer base, though there is room for improvement.
• 31 to 70: Great (Favorable). Indicates strong customer loyalty, positive customer experience, and healthy growth.
• 71 to 100: Excellent (World Class). Extremely rare and represents top-tier customer loyalty and brand advocacy.
