Employee Turnover Cost Calculator

Key Points at a Glance

• The cost of an employee leaving is modeled as a multiple of the annual salary—adjustable between 0.25 and 2.0, with a default value of 0.75.
• This includes recruiting, onboarding, the loss of productivity until the replacement reaches full capacity, and administrative tasks.
• The factor is an estimate, not an actual value—it depends heavily on position, industry, and the time it takes to fill a vacancy.
• The savings figure shows what achieving a lower target rate would mean in mathematical terms. The calculator does not indicate whether or how this target will be achieved.

Why Employee Turnover Is More Expensive Than It Seems

An employee’s departure doesn’t just cost money when the position is refilled. The costs begin with the loss of productivity during the notice period, continue through the job posting, selection, and contract negotiation phases, and don’t end until the replacement has reached full productivity. Because these expenses are allocated to different cost centers, the total amount doesn’t appear in any analysis.

How the Computer Performs Calculations

The number of employees multiplied by the turnover rate equals the number of departures per year. This figure, multiplied by the cost per departure—the average annual salary multiplied by the selected cost factor—equals the annual turnover costs.

The Cost Factor

This factor is both the key adjustment and the greatest source of uncertainty. 0.75 of the annual salary is a deliberately conservative default setting. It is higher for positions requiring a long training period, a tight candidate market, or high customer retention, and lower for roles that can be filled quickly. The percentage breakdown across recruiting, onboarding, productivity, and administration is a model assumption used by this calculator—adjust it until it fits your organization’s needs.

What a lower rate would be worth

The calculator estimates the difference between the actual and target rates in euros. This is not a forecast or a guarantee of a measure’s effectiveness, but rather an order of magnitude: it shows you what budget for customer retention measures might be mathematically worthwhile.

What the computer can't do

Simplified sample calculation provided without guarantee. The cost per exit and the percentage breakdown are model assumptions that you set yourself—they are not actual measured values, nor do they represent guaranteed results.

Frequently Asked Questions

How much does it cost to replace an employee?

The cost of an employee leaving is typically modeled as a multiple of their annual salary. This calculator uses an adjustable factor ranging from 0.25 to 2.0 times the annual salary; the default setting is 0.75. This figure includes recruiting, onboarding, the loss of productivity until the replacement reaches full performance, and administrative costs.

How do you calculate employee turnover costs?

Multiply the number of employees by the turnover rate to determine the number of departures per year. Then multiply that number by the cost per departure—that is, the average annual salary multiplied by the selected cost factor.

What are the benefits of a lower employee turnover rate?

The savings correspond to the difference between the current and target turnover rates, multiplied by the number of employees and the cost per employee who leaves. The calculation does not indicate whether or how the target turnover rate will be achieved—it merely quantifies what the savings would be worth.

Sample Calculation

A company with 100 employees, a turnover rate of 12 percent, and an average annual salary of 48,000 euros.

• Cost per withdrawal: 48,000 euros × factor 0.75 = 36,000 euros
• Resignations per year: 100 × 12 percent = 12
• Annual turnover costs: 12 × 36,000 euros = 432,000 euros

If the rate drops from 12 to 9 percent, that means three fewer departures per year—which amounts to approximately 108,000 euros. This is a simplified example calculation provided for illustrative purposes only; the cost factor and target rate are assumptions.

Sources and Assumptions

This calculator does not rely on any external statistics. All input values—number of employees, turnover rate, average annual salary, and cost per employee departure—are assumptions that you set yourself. The default setting of 0.75 annual salaries per employee departure is a deliberately conservative estimate used by this calculator and is not based on actual data.
