## Hero

Calculate the cost of workforce guessing.

Explore a directional opportunity range for developing internal capability before hiring externally, reducing avoidable attrition, and protecting critical knowledge.

Private. Secure. Your data stays with you.

## Calculator Inputs And Defaults

1. Total employees
   Default 250. Range 10 to 10,000.
2. Avg. annual salary
   Default EUR 30,000. Range EUR 25,000 to EUR 150,000.
3. Annual turnover rate
   Default 10%. Range 1% to 30%. Industry note: 15-20%.
4. Replacement cost
   Default 1.5x salary. Benchmark: 1.5-2.0x.
5. Retention impact
   Default 20% reduction in avoidable turnover.
6. Ramp speedup
   Default 25% faster productivity for supported hires.
7. Internal mobility rate
   Default 3% of employees moving internally per year.
8. Recruiter fee avoidance
   Default 20% of salary saved per internal fill.
9. Build-versus-hire shift
   Default 15% of vacancies developed internally.
10. Knowledge exposure
   Default 15% of exits carrying critical knowledge.

## Calculator Outputs

- Estimated annual savings across retention, capability, knowledge, mobility, and ramp
- Three-year opportunity before compounding
- Share of payroll
- Savings composition by lever

## Formula Levers

1. Keep your best people
   Departures x retention impact x replacement cost multiple x average salary.
2. Build from within
   Departures x build-versus-hire shift x 0.5 salary premium avoided.
3. Protect critical knowledge
   Departures x knowledge exposure x 0.5 salary at risk.
4. Move talent where it matters
   Employees x internal mobility rate x average salary x recruiter fee avoidance.
5. Accelerate new hires
   Departures after retained exits x average salary x 0.25 ramp cost x ramp speedup.

## Savings Composition Defaults

- Retain critical people: 54% default share
- Build capability: 13% default share
- Protect knowledge: 13% default share
- Move talent: 11% default share
- Ramp faster: 9% default share

## Assumptions

- Replacement cost (1.5x salary): Replacing an employee typically costs 1.5-2.0x annual salary once recruiting, onboarding, lost productivity, and ramp are included (Gallup, Bersin). The model defaults to the conservative end and drives the retention lever.
- Retention impact (20%): Visibility into growth paths, internal opportunity, and capability investment reduces avoidable turnover. The model assumes 20% fewer annual departures, valued at full replacement cost.
- Build-versus-hire shift (15%): A share of vacancies can be filled by developing internal people instead of hiring externally. Each shifted role avoids roughly half a salary in external hiring premium, conservative within published replacement-cost ranges.
- Internal mobility (3% per year): A realistic share of employees moves internally each year when opportunity is visible. Each internal fill avoids external recruiting fees of 15-25% of first-year salary; the model credits 20%.
- Ramp speedup (25%): New hires take roughly six months to reach full productivity, putting about a quarter of an annual salary at stake per hire. Structured support and knowledge transfer recover 25% of that ramp cost.
- Knowledge exposure (15% of exits): A minority of departures concentrate critical, undocumented knowledge. The model assumes 15% of exits carry knowledge risk, costing half a salary each in rework, delay, and quality loss, conservative against published estimates.
