Formula
% Promoters (9-10 score) - % Detractors (0-6 score)
How to measure
Survey employees with 'How likely are you to recommend working here to a friend?' on a 0-10 scale, then subtract detractor percentage from promoter percentage.
Why track it
eNPS is a leading indicator of retention and recruiting difficulty, both of which directly affect a growing company's ability to execute.
Example
A startup's eNPS drops from 55 to 20 after a difficult layoff round, prompting leadership to address morale before it affects hiring.
