Employer leaders reviewing workforce costs and priorities

Free Employer Tool

Put a planning value on employee turnover.

Use your own assumptions to estimate annual turnover exposure and the value of a realistic improvement scenario.

Estimate the Cost

Turnover Cost Calculator

Make every assumption visible.

The math is straightforward. Accuracy depends on using the right employee group, a true voluntary-turnover rate, and a replacement-cost assumption you can explain.

The Calculation

Three transparent steps.

  1. Estimated departuresAverage employee count x voluntary turnover rate
  2. Cost per departureAverage annual pay x replacement-cost percentage
  3. Annual exposureEstimated departures x cost per departure

Enter your workforce assumptions

The starting values are examples, not benchmarks. Replace them with one consistent role group, location, or employee population before using the result in a business decision.

Use average active headcount for the same 12-month period as the departures. A simple method is beginning headcount plus ending headcount, divided by two. Monthly averages are better when staffing changes significantly.
Average active headcount during the year.
Divide voluntary departures during the year by average employee count, then multiply by 100. Keep layoffs, discharges, retirements, and internal transfers out unless you intentionally want a broader separation measure.
Voluntary departures divided by average headcount.
Use average base pay for the roles being analyzed. Separate very different role groups because pay, recruiting difficulty, vacancy time, and training needs can make one blended average misleading.
Use an average for one reasonably similar role group.
This is the estimated cost of one departure as a percentage of annual pay. It may include recruiting, interview time, vacancy coverage, overtime, onboarding, training, supervisor time, and lost productivity. The 33% starting value is an example only, not a universal benchmark.
Build this percentage from costs your leaders accept.
Enter percentage points, not percent improvement. Moving from 20% turnover to 15% turnover is a 5-point reduction. The scenario value is planning potential, not guaranteed savings.
Example: 20% turnover reduced to 15% is a 5-point improvement.

Private by design: values stay in this browser tab. They are not saved or sent to Main Street.

Improve the Accuracy

Use records before rules of thumb.

Run separate estimates for materially different role groups. Replace the cost percentage with actual recruiting expense, vacancy coverage, overtime, onboarding, training, supervisor time, and time-to-productivity information where available.

The useful question is not whether every departure costs the same amount. It does not. The useful question is which assumptions leadership accepts, which roles create the greatest disruption, and what level of improvement justifies action.

This is a planning estimate based only on the values entered. It is not an accounting valuation, financial forecast, or guarantee of savings.
