Employee NPS (eNPS) calculator
Promoter, passive and detractor counts in, and out comes the employee net promoter score, from minus 100 to plus 100. No benchmark, no good score asserted.

How the answer is worked out
Every step, in the open, so you can rebuild it in a few spreadsheet cells and disagree with it if you want to. A calculator you cannot check is an ad.
The three groups
Responses are grouped into promoters, passives and detractors. On the usual zero to ten question, nines and tens are promoters, sevens and eights are passives, and zero to six are detractors. That split is the common convention, and the tool notes it, but it does not impose it: you enter the counts you have already grouped, so you can draw the boundaries differently if your survey does.
The score
The three counts add up to the total responses. Promoters and detractors are each taken as a percentage of that total, and the score is the promoter percentage minus the detractor percentage. Sixty promoters and fifteen detractors in a hundred responses is sixty percent minus fifteen percent, a score of forty-five. Passives are in the total, so they dilute both shares, but they never move the score on their own.
Reading the score
The result runs from minus 100, everyone a detractor, to plus 100, everyone a promoter. It is a snapshot of one moment, not a trend, and it says how people answered, not why. The number is most useful read against your own earlier scores and across teams, measured the same way each time, rather than against any outside figure.
What this tool does not know
What a good score is. It asserts no benchmark, because a score that reads well in one sector, region or company size reads differently in another, and a borrowed number tells you little about your own team. The comparison that means something is your own score over time, measured the same way, which the tool leaves you free to build.
It also cannot tell you why people answered as they did, and a small number of responses makes the score jumpy, so treat a figure from a handful of people with care. For the related people signals, see the turnover rate calculator and the absenteeism rate calculator, and for the wider picture the guide to HR metrics for small teams.
Questions with complete answers
What is eNPS?
Employee net promoter score is a single figure from a one-question survey, usually how likely someone is to recommend the organisation as a place to work on a zero to ten scale. Responses are grouped into promoters, passives and detractors, and the score is the share of promoters minus the share of detractors. It runs from minus 100 to plus 100.
How is the score worked out?
The tool takes the three counts you enter, adds them to a total, and works out each group as a percentage of that total. The score is the promoter percentage minus the detractor percentage. Passives count toward the total, and so pull both percentages down, but they do not add to or subtract from the score directly. Every line is shown in the working.
What is a good eNPS?
This tool asserts none. What counts as a strong score varies by sector, region, company size and the moment you ask, and a benchmark copied from a web page tells you little about your own team. The useful comparison is your own score over time and between teams, measured the same way each time, which is something you can do and a benchmark cannot.
How many responses do I need?
Enough that a few answers cannot swing the result. With a small number of responses a single detractor moves the score sharply, so a score from a handful of people is noisy and easy to over-read. The tool flags a small sample rather than pretending the figure is solid, but it sets no minimum, because the right size depends on your team and how you will use the number.
Is anything I type saved or sent anywhere?
No. It computes in your browser and nothing is sent anywhere. There is no email wall, no account and no storage. The link button carries your figures in the address itself if you want to send them to someone.
A score is a snapshot. What people do next is the record worth keeping.
