Estimate how a leadership-pipeline retention initiative changes expected departures and replacement spending. Supply the covered population, the current and expected annual turnover rates, and your estimated cost to replace one participant. The result focuses on avoided exits, with supporting views of retained payroll capacity and replacement-cost savings. This is a planning model, not a promise: it works best when the two turnover rates are based on comparable employee groups and time periods.
Retained people = Population × (Current turnover rate − Expected turnover rate)
Replacement cost avoided = Retained people × Cost per departure
A positive result represents departures potentially avoided in one year. A negative result signals that expected turnover is higher than the current rate.
Replacement cost is user supplied and may include recruiting, onboarding, vacancy coverage, and ramp-up costs. Avoid counting the same cost twice.
For 100 people, reducing turnover from 18% to 12% avoids 6.0 departures. At $35,000 per departure, modeled replacement-cost savings are $210,000.
The calculator gives a one-year steady-state estimate. Build separate yearly scenarios if population or rates will change.
Use costs relevant to your organization, such as recruiting, onboarding, vacancy coverage, and productivity ramp-up.
It becomes negative when the expected turnover rate is higher than the current rate, indicating additional exits.
Count them only if your turnover definition treats transfers out of the pipeline as departures, and apply that rule consistently.
No. It is a scenario estimate; causal impact requires a suitable comparison or evaluation design.

| Population | People covered by the leadership pipeline |
| Current turnover | Observed annual departure rate |
| Expected turnover | Scenario rate after the initiative |
| Replacement cost | Estimated incremental cost for one departure |
