Employee Turnover Cost Calculator

Employee Turnover Cost

Replacing an employee costs far more than most managers realize. Research from SHRM (Society for Human Resource Management) and Gallup consistently puts the total cost of turnover at 50–200% of an employee’s annual salary, depending on seniority and specialization.

Cost categories:

Typical total cost by role level:

Annual turnover impact:

If you have 100 employees, a 20% annual turnover rate means replacing 20 people per year. At $75,000 average salary and 100% replacement cost, that is $1,500,000 per year in turnover costs.

Reducing turnover: A 10% improvement in retention often costs far less than continuing to replace employees. Key retention levers: competitive compensation, career development, flexible work, recognition programs, and strong management relationships.

ROI of retention programs: If a retention program costs $200,000/year but reduces turnover from 20% to 15%, the savings on a 100-person team at $75,000 average salary come to $375,000.
That is a clear positive return, and it is also the argument that gets retention budgets approved. Finance sees the program cost on a line item every month. The turnover cost is spread across a dozen departments and never adds up anywhere, which is exactly why it gets ignored.

A note on the lost productivity figure

It is the softest number here and usually the largest. The calculator values it as the departing salary for the months a replacement spends below full output. That is a reasonable proxy and it is what most HR models use, but it understates a senior role where the gap costs other people’s time too, and overstates a role where the team simply absorbs the work for a few weeks. Treat it as a range, not a figure to put in front of a board.
