How NPS is Calculated

Promoters
Score: 9–10

Loyal enthusiasts who will keep buying and refer others.

Passives
Score: 7–8

Satisfied but unenthusiastic. Vulnerable to competitive offerings.

Detractors
Score: 0–6

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

Formula

NPS = ((Promoters − Detractors) ÷ Total Respondents) × 100

Passives are counted in the total but do not affect the score directly. NPS ranges from −100 to +100.
