とは何か Quiet Quitting Cost Calculator?

The Quiet Quitting Cost Calculator quantifies the financial impact to employers of employee disengagement — workers who do the minimum required to avoid termination but don't go beyond contracted duties. The term gained mainstream traction in 2022 via TikTok and represents a broader Gallup-identified phenomenon: only ~32% of US employees are engaged, ~50% are 'not engaged' (going through motions), and ~18% are 'actively disengaged' (undermining engaged colleagues). Disengagement carries two cost layers: (1) Direct productivity decline — Gallup research shows engaged workers are 18–23% more productive than disengaged peers, with quality output gaps even larger; (2) Elevated turnover risk — actively disengaged employees leave at 3.3× the rate of engaged employees per Gallup, and turnover costs run 0.5–2× annual salary for knowledge work (recruiting, onboarding, productivity ramp, knowledge loss). Calculator inputs salary, count of disengaged employees, productivity loss %, and turnover risk %, then computes annual cost. Formula: Annual Cost = Disengaged Count × Salary × (Productivity Loss% + Turnover Probability × 1.5). For 10 disengaged employees at $75k salary with 20% productivity loss and 25% annual turnover risk, that's 10 × $75k × (0.20 + 0.25 × 1.5) = 10 × $75k × 0.575 = $431k annually. Multiply by team count for organization-wide impact — a 500-person company with 18% actively disengaged plus 50% not-engaged faces millions in hidden cost. The calculator is intended for HR leaders building business cases for engagement investment, managers understanding the financial stakes of team morale, and executives evaluating retention initiatives. Most engagement research finds 60–70% of disengagement is preventable via manager training (specifically: clarifying expectations, recognizing good work, providing growth opportunities, addressing systemic friction). Engagement initiatives that succeed typically pay back 5–10× in productivity and retention savings. Calculator output translates engagement scores into board-room dollar figures.

方法 Quiet Quitting Cost Calculator

  1. 1Step 1 — Enter average salary of the affected role
  2. 2Step 2 — Enter number of disengaged employees (use engagement survey data or estimated 50% if no data)
  3. 3Step 3 — Set productivity loss % (default 20% — Gallup baseline for disengaged vs engaged)
  4. 4Step 4 — Set turnover risk % (default 25% — disengaged annual departure rate)
  5. 5Step 5 — Calculator computes productivity decline cost: N × Salary × PL
  6. 6Step 6 — Calculator computes turnover risk cost: N × Salary × TR × 1.5
  7. 7Step 7 — Outputs annual total, per-employee impact, monthly cost, and turnover probability

解いた例

例 1Mid-size team disengagement
入力:$75k salary, 10 disengaged, 20% prod loss, 25% turnover
結果:~$431k annual ($43k per employee/yr)

10 × $75k × (0.20 + 0.25 × 1.5) = $431k. Breaks down: $150k productivity loss + $281k turnover risk.

例 2High-turnover service role
入力:$45k salary, 30 disengaged, 15% prod loss, 40% turnover
結果:~$1.0M annual

Retail / hospitality: lower productivity loss but extreme turnover

30 × $45k × (0.15 + 0.40 × 1.5) = $1.01M. Turnover dominates in service roles.

例 3Enterprise knowledge worker
入力:$120k salary, 50 disengaged, 25% prod loss, 20% turnover
結果:~$3.3M annual

50 × $120k × (0.25 + 0.20 × 1.5) = $3.3M. Knowledge workers have high productivity loss costs and high turnover replacement costs.

よくある質問

Q

Is 'quiet quitting' always negative for employers?

A

Mostly — but some 'quiet quitters' are correctly defining work-life boundaries against unreasonable employer expectations (unpaid overtime, scope creep, lack of recognition). The cost to employers is real when boundaries cross into withholding effort, expertise, or institutional knowledge that the role implicitly requires. Healthy boundaries should not be confused with disengagement; the difference is whether the contracted role itself is being performed well.

Q

How accurate is the 20% productivity loss assumption?

A

Gallup's State of the Workplace report estimates engaged employees are 18–23% more productive than disengaged peers; this is the source of the 20% default. Specific roles vary — creative/innovation work shows larger gaps (40%+) since engagement drives discretionary effort; routine task work shows smaller gaps (10–15%). Adjust for your context.

Q

What's the cheapest way to reduce disengagement?

A

Manager training. Gallup finds 70% of variance in engagement is explained by direct manager quality — not pay, benefits, or company-wide programs. Specific interventions with strong ROI: regular 1:1s with clear expectations, public recognition for good work, removing systemic friction, and providing growth opportunities. Effective manager training programs cost $2–5k per manager and typically pay back 5–10×.

Q

Should I include 'not engaged' employees, not just 'actively disengaged'?

A

Probably yes — 'not engaged' (50% of US workforce per Gallup) means going through motions without enthusiasm, which shows up as productivity decline though less dramatic than active disengagement. Include them at lower productivity loss % (10–15%) and lower turnover % (15%) for a more complete picture. Active disengagement alone may understate the total cost.

Q

Does remote work increase disengagement?

A

Mixed evidence. Some research finds remote workers slightly more engaged (autonomy, flexibility); other studies find junior employees particularly disengage remotely (lack of mentorship, fewer informal connections). The biggest factor remains direct manager quality regardless of work location. Hybrid models with 2–3 office days typically show best engagement scores.

避けるべきよくある間違い

  • !Underestimating turnover cost (typically 1.5× salary for knowledge work, can reach 2–3× for specialized roles)
  • !Ignoring contagion to engaged team members (disengagement spreads)
  • !Confusing healthy work-life boundaries with disengagement (different phenomena)
  • !Treating all disengagement as employee fault (manager and systemic issues drive most cases)
  • !Investing in company-wide perks instead of manager training (lower ROI)
💡

プロのヒント

Engagement surveys typically show 60–70% of cost is preventable through manager training — the cheapest intervention is fixing how middle managers interact with their teams. Specific high-ROI moves: weekly 1:1s, clear expectations, public recognition, removing process friction, and providing growth opportunities. Annual manager development programs at $2–5k per manager pay back 5–10×.
