NPS comes from a single survey question: "How likely are you to recommend us to a friend or colleague?" answered on a scale from 0 to 10. Responses are grouped into three segments, and the score is the difference between the top and bottom groups.
NPS = % promoters - % detractors
The result is always a whole number between -100 (everyone is a detractor) and 100 (everyone is a promoter). It is written as a plain number, not a percentage.
An NPS tells you how people feel in aggregate. It does not tell you why. A score of 20 could mean your onboarding is confusing, your pricing feels wrong, or a key feature is missing: the number alone cannot distinguish between them. Small samples make it worse, since a few responses can swing the score dramatically.
The fix is follow-up feedback. Ask detractors what went wrong and promoters what they would miss most. Our survey question generator has a set of NPS follow-up questions written for exactly this. And if you want that feedback to turn into a ranked backlog instead of a spreadsheet, a feature voting board like FeatQ lets the same users vote on what you should build next.
Practical answers about agents, voting, embeds, and pricing.
NPS is the percentage of promoters (people who answered 9 or 10) minus the percentage of detractors (people who answered 0 through 6). Passives (7 or 8) count toward the total number of responses but do not add or subtract. The result is a whole number between -100 and 100.
There is no universal answer, and be wary of anyone selling you one. A score above 0 means you have more promoters than detractors, and above 50 is commonly considered strong. What matters more is your own trend over time and what the follow-up feedback says.
That is how the convention defines it: passives are treated as satisfied but unenthusiastic, so they neither help nor hurt the score. They still affect it indirectly because they increase the total, which shrinks both percentages.
Your numbers are stored in localStorage on your device and never sent to a server. Come back on the same browser and they will still be here. Reset wipes them.
More is better. With a handful of responses, one person switching from promoter to detractor swings the score wildly. Treat small-sample scores as a rough signal, not a metric to steer by, and always read the written feedback behind the numbers.
