Why Most eNPS Scores Are Wrong (And Why Officevibe's Math Inflates Yours)

Most companies report an eNPS score every quarter. Most of those scores are mathematically wrong — usually inflated by the platform calculating them.

This isn't a minor technicality. The math you use determines what the score tells you, and the wrong math hides the most important signal: the Passive segment, which is the canary in the coal mine for retention.

Here's the right formula, why most platforms get it wrong, and what to track instead.

The correct eNPS formula

Standard Employee Net Promoter Score:

"How likely are you to recommend [company] as a place to work?" — scale of 0 to 10

Buckets:

• 9 or 10: Promoter
• 7 or 8: Passive
• 0 to 6: Detractor

Formula:

eNPS = (% Promoters) − (% Detractors)

Range: -100 to +100. Above 0 means more would recommend than warn off. Above 30 is good. Above 50 is exceptional.

The critical detail most platforms miss: Passives are included in the denominator but excluded from the math. They count toward the response total — they just don't affect the score directly.

Example with 100 respondents:

• 40 Promoters (40%)
• 35 Passives (35%)
• 25 Detractors (25%)

eNPS = 40 − 25 = +15

That's the standard formula. Easy to compute, easy to compare across companies and quarters, comparable to NPS in any context.

How major platforms get it wrong

Some HR engagement platforms — most notably Workleap Officevibe — exclude Passives entirely from the calculation. This produces a mathematically different (and inflated) score.

Their formula (or its equivalent):

eNPS = (% Promoters) − (% Detractors), where Passives are removed from the total first

With the same 100-respondent example, removing the 35 Passives first:

• 40 Promoters out of 65 remaining = 61.5%
• 25 Detractors out of 65 remaining = 38.5%

eNPS = 61.5 − 38.5 = +23 (vs. the correct +15)

The score is inflated by 8 points just by changing the math. Across multiple quarters and segments, the inflation compounds.

This is well-documented in HR-analytics blogs (CultureMonkey, Wrenly, etc.) and criticized by users on G2. It's not malicious — Officevibe explicitly documents their methodology — but it makes your score incomparable to industry benchmarks and to NPS calculations from any other tool.

Why Passives matter more than you think

Passives are the segment most companies ignore. They're the "fine, no complaints" responses. They didn't say anything bad, so the assumption is: they're stable.

The reality: Passives are the leading indicator of retention crises.

Most employees who quit weren't Detractors in their last survey before resigning. They were Passives. They downshifted from Promoter to Passive 6–12 months before they downshifted from Passive to Detractor — and they usually quit before they ever became Detractors.

This is consistent across most published employee retention research. Track Passive % over time and you'll see retention problems coming 2 quarters before your engagement score drops or your turnover number ticks up.

The implication: if you only look at your eNPS score and ignore the Passive distribution, you'll miss the earliest warning signal you have access to.

What to track instead of just the score

The 3-number scorecard that actually works:

1. eNPS score (using the standard formula)

• Industry-comparable
• Trends over time
• Use it for the headline metric

2. Passive percentage as a separate number

• Watch the trend; trend matters more than the absolute value
• If Passive % grows from 20% to 35% quarter-over-quarter, you have a problem coming
• A flat or declining Passive % alongside a stable score is healthy; rising Passives despite a stable score is the warning sign

3. Promoter → Detractor flow rate

• Of the people who were Promoters last quarter, what % became Passives or Detractors this quarter?
• High flow rate = retention crisis brewing
• Low flow rate = stable

You can't get #3 from anonymous data (because you can't link this quarter's response to last quarter's). But you can approximate it by tracking the Promoter % trend: if it's dropping faster than the Detractor % is rising, the difference is going into the Passive bucket.

How to run eNPS correctly

See our eNPS template → for the actual form. The methodology:

Cadence

• Monthly cadence is the standard for engagement-focused teams. Catches changes before they become resignations.
• Quarterly cadence is acceptable for stable teams; misses faster signals.
• Annual is too slow; by the time you see the data, the moment has passed.

Survey design

• 3 questions max: the score (required), what's driving your score (text, optional), what would make you more likely to recommend (text, optional)
• No demographic questions that segment small teams below 10 — anonymity breaks
• Anonymous by default — eNPS only works if respondents trust it; named tools (HRIS-integrated) inflate the score systematically

Response rate

• Aim for ≥60% response rate
• Below 50%, your sample biases toward the loudest voices on either end
• Encourage participation with one reminder; never more

Sharing results

• Within 1 week of close: share the score + trend + Passive % with the whole team
• Within 2 weeks: share 2–3 themes from text responses (anonymized)
• Within 1 month: pick ONE action per quarter based on the top theme

The single biggest predictor of next quarter's response rate: did the team see visible action from last quarter's responses.

When eNPS is wrong (the limitations)

eNPS is a single number summarizing a complex thing. Treat it as a signal, not a verdict:

• Sample bias: small teams + low response rate = score driven by 3 loud people
• Recency bias: a score collected the week after a layoff reflects the layoff, not the trend
• Survey fatigue: scores trend down as surveys get more frequent without producing visible action
• Industry variance: a 30 in B2B SaaS is mediocre; a 30 in telecom is exceptional

The right way to use eNPS: as part of a triangulated picture (along with turnover, exit interview themes, manager 1:1 patterns), not as a standalone leadership KPI.

What to do if you're stuck with Officevibe's math

If you can't switch tools, do this:

1. Report the score Officevibe shows you (it's what your leadership expects)
2. Separately calculate the standard eNPS from the raw Promoter/Passive/Detractor breakdown (most tools show the breakdown even if they calculate the score differently)
3. Track both internally — Officevibe's score for trend continuity, standard score for industry comparison
4. Always show Passive % alongside the score

If you can switch tools, switch. The platform-side methodology shouldn't determine what your retention strategy is reading. Anonymeter uses the standard formula and exports raw data via CSV so you can verify the math yourself.

Bottom line

eNPS works as a metric when calculated correctly. The standard formula — % Promoters minus % Detractors, with Passives in the denominator — produces an industry-comparable number that catches retention crises early.

Most HR platforms calculate it correctly. A few (notably Officevibe) inflate the score by excluding Passives. If you're using one of the platforms with non-standard math, you're seeing an artificially good number.

Watch the Passive %. That's where retention problems show up first.
