How NPS is calculated

NPS is based on a single question: "On a scale of 0 to 10, how likely are you to recommend [Brand] to a friend or colleague?" Respondents who answer 9 or 10 are Promoters; those who answer 7 or 8 are Passives; those who answer 0 to 6 are Detractors. The score is Promoters (%) − Detractors (%), which produces a number from −100 (every respondent is a detractor) to +100 (every respondent is a promoter). Passives are excluded from the formula, though they matter as a conversion opportunity.

Why NPS connects to social marketing

Promoters are the people who leave positive reviews, refer friends, and share brand content without prompting — in social terms, they are your organic amplifiers. A brand with a high NPS has an audience that is predisposed to positive word of mouth, which makes every social post more likely to earn shares and comments that extend its reach. A brand with a declining NPS is managing a sentiment problem that social publishing alone cannot fix, and that problem will surface in negative comments, low engagement, and reputation monitoring signals.

A concrete example

A company surveys 200 customers and gets 80 Promoters (40%), 70 Passives (35%), and 50 Detractors (25%). NPS = 40% − 25% = 15. Three months later, after resolving a widely-discussed product issue, a follow-up survey yields 100 Promoters (50%), 60 Passives (30%), and 40 Detractors (20%). NPS climbs to 30. During that same period, organic social shares of brand content doubled — a correlation worth examining, as sentiment and organic amplification often move together.

How to track and act on NPS

Run NPS surveys at consistent intervals — typically after key customer milestones or on a quarterly basis — using a fixed methodology so trends are comparable. A single score is less useful than the trend direction and the open-text follow-up ("Why did you give that score?"), which surfaces the specific issues driving detractor responses. For social strategy, treat NPS as a leading indicator: rising scores suggest your audience will amplify content; falling scores suggest community management and product reputation need attention before reach can grow.
