The NPS Calculation

Calculate your NPS using the answer to a key question, using a 0-10 scale: How likely is it that you would recommend [brand] to a friend or colleague?

Respondents are grouped as follows:

Promoters (score 9-10) are loyal enthusiasts who will keep buying and refer others, fueling growth.

Passives (score 7-8) are satisfied but unenthusiastic customers who are vulnerable to competitive offerings.

Detractors (score 0-6) are unhappy customers who can damage your brand and impede growth through negative word-of-mouth.

Subtracting the percentage of Detractors from the percentage of Promoters yields the Net Promoter Score, which can range from a low of -100 (if every customer is a Detractor) to a high of 100 (if every customer is a Promoter).
