Net Promoter Score Calculator: calculate net promoter score for your business. Formula, benchmarks, and practical tips included.
NPS = (Promoters ÷ Total) × 100 − (Detractors ÷ Total) × 100
Worked example: 200 responses. 90 score 9–10 (Promoters). 60 score 7–8 (Passives). 50 score 0–6 (Detractors). NPS = (90/200 × 100) − (50/200 × 100) = 45 − 25 = 20.
