The free workforce cost calculator that quantifies the hidden financial cost of staff turnover, management friction, disengagement, and absence — then shows you exactly what you could recover.
Free to use · No account required · Takes under 3 minutes
Most organisations track payroll and headcount. Almost none capture the full financial drag sitting beneath those headline numbers. Staff turnover costs extend well beyond recruitment fees — they include the 25% productivity gap while a new hire ramps up, the management time absorbed by the hiring process, and the knowledge lost when experienced people leave. According to SHRM research, total replacement cost runs 1.5–2× annual salary per leaver.
Disengagement compounds the problem. Gallup's State of the Global Workplace 2025 found that only 23% of employees are actively engaged, with actively disengaged workers showing a 34% productivity deficit compared to engaged peers. In the US alone, Gallup estimates this costs $1.9 trillion per year. Presenteeism — employees who are physically present but mentally absent — costs a further 2–3× the value of recorded absence, per CIPD's Health and Wellbeing at Work Report.
This calculator brings all four cost drivers together in one place. Enter your organisation's data — or use the pre-filled research benchmarks — and get an instant, currency-accurate view of your total annual people cost, alongside a modelled recovery path showing what targeted improvement would return. You can run the full calculator in under three minutes, or browse the 17 research sources that underpin every benchmark.

The four cost drivers
Most organisations track headcount and payroll. Almost none capture the compounding financial drag sitting beneath those headline numbers.
Recruitment fees, interview time, onboarding, and the productivity gap while roles sit vacant add up faster than most finance teams expect.
Every hour a manager spends on performance issues, conflict, or disengaged team members is an hour not spent on strategy, delivery, or growth.
Gallup research consistently finds that actively disengaged employees operate at 34% lower productivity — and most organisations undercount them.
Unplanned absence is visible. Presenteeism — people physically present but mentally checked out — costs 2–3× more and goes almost entirely unmeasured.
