Use this calculator to turn coverage improvement assumptions into a consistent estimate of employees expected to remain. It keeps the period, capacity, and cost logic visible so HR and operations teams can compare alternatives without hiding key assumptions in a spreadsheet. Adjust the inputs to match one team, site, or planning window, then use the supporting results to identify the gap, cost, or change that deserves attention.
The main result estimates employees expected to remain from the values entered. Supporting figures show the scale and operational context, helping you distinguish a small rounding issue from a staffing decision that needs action.
This planning estimate is not legal, payroll, or financial advice. Results depend on the consistency and accuracy of your inputs.
For 250 employees, moving retention from 78% to 84% keeps an estimated 15 additional employees. At $12,000 per replacement, that is $180,000 in avoided replacement cost.
Yes. Keep every input on the same period basis; annualized results use only the periods or weeks you enter.
Include only the hours your organization treats as usable capacity or productive time. Apply the same rule to every compared value.
Only if you include them in the hourly cost assumption. The calculator does not add jurisdiction-specific employment costs automatically.
Run a low, expected, and high scenario. The spread is often more useful than a single point estimate.
No. It is a planning estimate; validate assumptions against schedules, payroll records, attrition cohorts, and operational constraints.

|---|---|
| Planning volume | Demand, people, shifts, or opportunities for one period |
| Capacity or outcome | Available hours, completions, or retained employees |
| Cost assumption | Use loaded cost only when the decision requires it |
