Answer eight short sections covering headcount, salary ranges, turnover, and current HR spend. Pre-filled benchmarks mean you can complete it in under three minutes, and every input can be overridden with your actual figures. Results are expressed in your local currency using live exchange rates.
How it works
Set your context: Select your country, industry sector, and company stage. The calculator automatically applies research-backed benchmarks for your location and sector using live FX rates.
Confirm your organisation details: Enter your total headcount, number of managers, and average salary. Pre-filled from ONS, BLS, ABS, or Eurostat benchmarks depending on your country.
Review staff turnover costs: Enter annual leavers and what percentage are avoidable. Choose external (agency) or internal recruitment. The calculator shows total replacement cost per person.
Estimate management friction: Set the percentage of manager capacity lost to people issues — conflict, communication failures, and cultural dysfunction. McKinsey research benchmarks this at 15–30% in dysfunctional environments.
Enter disengagement data: Input how many employees are actively disengaged. The Gallup 2025 global average is 77% non-engaged. The cost uses Gallup's 34% productivity loss benchmark.
Add absence and presenteeism: Enter total absence days and daily cost. A presenteeism multiplier (default 2.5×) accounts for hidden productivity loss from employees who are present but not fully effective.
Include external spend: Add any consultancy or L&D spend related to people and management issues. This is often overlooked but adds significantly to the true cost.

The calculator surfaces your total annual people cost across all drivers, benchmarked against sector norms and backed by institutional research from Gallup, CIPD, SHRM, McKinsey, Mercer, and more — see the full source list.
