Interpreting Results
Start with Total Responses. Then compare Nps Score and Promoter Percent before deciding what changes the answer most.
Input Steps
Field by field
- 1
Promoters
Enter counts for promoters, passives, and detractors, and optionally select an industry benchmark. NPS is promoter percent minus detractor percent, so the mix matters as much as the final score.
- 2
Passives
Read total responses, NPS score, promoter, passive, and detractor percentages, classification, benchmark delta, and trend guidance. As a rough guide, 70+ is Excellent, 30-69 is Good, 0-29 needs improvement, and below 0 is poor.
- 3
Detractors
Interpret the score with the mix. A decent NPS with a large passive block means onboarding and product education may reveal upside, while high detractor share signals immediate churn and reputation risk even if the overall score is not catastrophic.
- 4
Industry
Use the guidance to pick the next action for the next 30 days: detractor recovery, passive-to-promoter conversion, or referral capture. If you are below industry benchmark by 5 points or more, start with root-cause interviews before spending harder on acquisition.
- 5
Setup
Re-run monthly or quarterly using the same survey method. Track NPS and detractor percent together because a flat score can still hide worsening service risk if promoter gains merely offset growing dissatisfaction.
Run one base case and one sensitivity case before trusting a single output.
