How to Read and Verify the Net Promoter Score Calculator Output

The output panel reports the exact result derived from Input mode, Detractors (scores 0-6), Passives (scores 7-8) alongside any unit or formatting notes.

The result is the NPS value and response-group shares. Summarize survey counts or supplied individual scores.

The score reflects the entered responses and does not assess sampling quality or significance.

Numerical output shows up to 12 significant digits. Floating-point arithmetic and display rounding can affect the last digits.

Example input
Input mode = Grouped counts; Detractors (scores 0-6) = 10; Passives (scores 7-8) = 20; Promoters (scores 9-10) = 70; Raw integer scores 0 to 10 = 10,9,8,6
Example output
NPS: 60 Total responses: 100 Detractors: 10 (10%) Passives: 20 (20%) Promoters: 70 (70%)
