FAQ
What does this tool tell you?
The Developer NPS Calculator computes dNPS from promoter and detractor percentages.
What affects the result most?
Developer NPS (dNPS): 'How likely to recommend working here to a colleague?' 0-10 → NPS = promoters% - detractors%. NPS calculation: >9 = promoter, 7-8 = passive, 0-6 = detractor — same as standard NPS. Action threshold: if dNPS drops >10 points quarter-over-quarter, treat as incident — find root cause.
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
