Instructions
How to use this app
- Use average headcount over the period, and count leavers you want included in turnover under your own policy.
- Split out leavers in their first six months to see how much turnover comes from early exits.
- Fill in cost components from your own records, not from generic surveys.
- Use vacancy days and a daily cost only if a vacant role has a real cost, such as overtime or lost output.
- Set a goal for reducing early exits to see what it would be worth, then check it after changes.
What This Turnover and Cost-of-Vacancy Calculator Helps You Decide
This calculator turns headcount and leaver counts into a turnover rate, builds a cost per replacement from components you enter, and shows the annual cost of turnover, the cost of early exits, and what reducing early exits would be worth.
Use it to size a retention or onboarding project, to compare the cost of a change with what it might save, and to show leaders that turnover has a price.
Core Formulas
| Measure | Formula | Meaning |
|---|---|---|
| Turnover rate | Leavers / average headcount | Share of the workforce that left in the period. |
| Early exits share | Leavers within 6 months / all leavers | How much of turnover comes from new hires. |
| Ramp-up loss | Weeks × weekly pay × (1 − productivity) | Value of output lost while a new hire reaches full productivity. |
| Vacancy cost | Days vacant × daily cost | Cost of cover or lost output while the role is empty. |
| Cost per replacement | Recruiting + training + ramp-up loss + vacancy | Total cost of replacing one person. |
Worked Example: A 250-Person Plant
The pre-loaded values show 45 leavers on an average headcount of 250, so turnover is 18.0%. Twenty of them, 44.4%, left in their first six months. Recruiting is $4,000, training $3,500, and ramp-up loss is 8 weeks × $1,100 × 50% = $4,400, so a replacement costs $11,900. Annual turnover therefore costs 45 × $11,900 = $535,500.
Early exits alone cost 20 × $11,900 = $238,000. Halving them avoids 10 leavers and saves about $119,000 a year. That is a goal, not a forecast, and the real saving depends on whether the changes work.
Limits and Good Practice
- Costs are estimates. Use components you can verify from your own records, and state assumptions.
- Turnover is not always bad. Some departures are healthy, so consider regretted and voluntary turnover separately.
- Correlation is not cause. Test explanations for early exits before acting, using exit and stay conversations.
- Keep data aggregate and follow your privacy rules. Do not enter information about individual employees.
Turnover and Cost-of-Vacancy Calculator Frequently Asked Questions
How is the cost of turnover calculated?
The calculator adds recruiting cost, onboarding and training cost, the productivity lost while a new hire ramps up, and the cost of the vacancy to get a cost per replacement, then multiplies by the number of leavers. You supply each component, so the result reflects your own roles rather than a generic estimate.
What is early-tenure turnover?
Early-tenure turnover counts people who leave within a set period after joining, commonly the first 6 or 12 months. It is a useful signal of the quality of hiring and onboarding, because early exits often trace back to selection, unmet expectations, or a weak start.
Should I include vacancy cost?
Include it only when a vacant role has a real cost, such as overtime paid to cover the work or output that cannot be made up. If existing staff absorb the work at no extra cost, leave it at zero, and state that assumption when you present the result.
Is my data stored anywhere?
No. The calculator runs in your browser and nothing is sent to a server. Enter aggregate numbers only, and do not enter names or other information about individual employees.
