Baseline case
A SaaS survey of 200 responses returns 120 promoters, 45 passives, and 35 detractors.
Across 200 total responses, NPS is 42.5: promoters at 60% minus detractors at 17.5%. Passives count toward the total but not the score. The result rates as Good.

Passives drag the denominator without helping the score, which is why 60% promoters yields only 42.5. Converting fence-sitters to promoters is the highest-impact move from here.

More promoters
An onboarding push wins 18 extra promoters, lifting the count to 138 with passives and detractors flat.
NPS climbs to 47.2 as the promoter share rises to 63.3% and the detractor share dips to 16.1%. Still rated Good, but closer to Excellent.

Adding promoters helps twice: it raises the promoter share and dilutes the detractor share at the same time. That double effect is why promoter growth moves NPS faster than anything else.

Fewer passives
Seven passives drop out of the sample (to 38), perhaps disengaging, with promoters and detractors unchanged.
NPS edges up to 44.0 on 193 responses, because removing passives shrinks the denominator and raises both the promoter and detractor shares.

Losing passives nudged the score up, but only by reshaping the percentages, not by adding fans. Do not mistake a higher NPS from a smaller sample for genuine improvement in sentiment.

More detractors
A rough release adds 12 detractors (to 47), holding promoters and passives steady.
NPS drops sharply to 34.4 as the detractor share jumps to 22.2% and the promoter share falls to 56.6%.

Twelve unhappy customers knocked more than eight points off the score, far more damage than the equivalent promoter gain added. Detractors are weighted heavily, so churn-risk recovery pays off fast.
