How is eNPS calculated?

Subtract the percentage of detractors (scores 0 to 6) from the percentage of promoters (scores 9 to 10). Passives (scores 7 to 8) are left out of the subtraction but still count in your response total. The final score sits somewhere between minus 100 and plus 100.

How we calculated this

The employee Net Promoter Score takes your promoters (people who answered 9 or 10 to "how likely are you to recommend working here") as a percentage of everyone who answered, and subtracts the detractors (0 to 6) as a percentage of the same total. Passives (7 or 8) sit in the total but not the subtraction, which is why a survey full of sevens scores near zero. The result runs from minus 100 to plus 100 and we place it against the bands practitioners commonly use. The arithmetic, the assumptions and the sources are all below.

Your working
Assumptions
  • Follows the Net Promoter method as Bain and Fred Reichheld defined it: promoters 9 to 10, passives 7 to 8, detractors 0 to 6, score equals % promoters minus % detractors. Change the bands and you are no longer measuring eNPS.
  • The bands (above 0 positive, 10 to 30 favourable, 30 and above strong, 50 and above excellent) are practitioner conventions rather than a published standard. Bain notes employee scores usually run lower than customer scores, so read yours against your own history before you read it against anyone else's.
  • The score is only as honest as the response rate. If 30 of 120 people answered, you have measured the 30 who felt strongly enough to answer, and the true score of the 120 is unknown. Enter counts, not percentages, so the tool can weight them properly.
  • One question tells you direction, not cause. A falling eNPS says something changed and nothing about what, so pair it with a question that asks.

What to do about it

An eNPS is a thermometer. It tells you the temperature moved and nothing about why, which is exactly why it travels so well to a board and so badly into a plan. These steps are for whoever runs the survey, whether or not they present the result.

1

Report the counts alongside the score

A score of 5 built from 40% promoters and 35% detractors is a divided workforce. A score of 5 built from 15% and 10% is an indifferent one. Same number, opposite problems. Put all three shares on the slide every time, because the score alone hides which one you have.

2
Where a tool helps

Cut it by team before you cut it by quarter

A company eNPS of 20 can hide a team at minus 30 under one manager. Cut it by team and by tenure, and look at the detractor share, because that is where resignations come from. Do this before you compare quarters, otherwise a good average hides the team that is about to walk.

3

Add one open question and read every answer

"What is the one thing that would move your score?" turns a number into a list. Read them all, code them into themes by hand if you have to, and take the top four to the leadership meeting with the score. That is the part that turns eNPS into a decision.

4

Set the cadence and keep it

Quarterly suits most organisations: often enough to see a trend, rare enough that people keep answering honestly. Bain suggests monthly for teams that will act on it monthly. Whichever you choose, the mistake that kills eNPS is running it once and then never acting on it, which trains people to stop answering.

5

Track it beside turnover and absence

Put eNPS, voluntary turnover, unplanned absence and internal moves on one chart by quarter. When the score drops and the exits and absences rise a quarter later, you have the lead indicator most HR reports lack, and a reason for the board to keep asking for it.

The score is the trend.
Step 2 is the why.

Compono Engage is an employee engagement platform that reads culture and climate alongside work personality, team by team, so a moving eNPS comes with the reasons attached instead of a slide to explain away. Most survey tools give you the score and a benchmark. Engage shows which teams are carrying the detractors and what in the climate is driving it, read against how the people in those teams prefer to work.

That is step 2 and step 3 done in one read, on a cadence you set, without a second survey. The score above tells you which way the temperature moved. Engage tells you where and why, which is the part a manager can act on.

Common questions

What is a good eNPS score?

Anything above 0 means you have more advocates than critics. A score of 10 to 30 is favourable, 30 and above is strong, and 50 and above is excellent. Context matters though. Industry, size, and how recently you surveyed all shift what counts as good for you.

How often should we measure eNPS?

Quarterly works for most teams. Often enough to spot a trend, rare enough that people do not tune it out. The single biggest mistake is measuring it once, reporting it, then never acting, which trains people to stop answering honestly.

Why use eNPS instead of a full engagement survey?

They do different jobs. eNPS gives you one trackable number that is easy to compare over time. A full engagement survey gives you the detail behind it. Run the score for the trend and the deeper read for the why, and you cover both.
