What attrition really costs me. The Employee Turnover Cost Calculator takes employees who left this year, average annual salary of leavers, replacement cost as a share of salary and returns annual cost of turnover plus cost per leaver. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Payroll figures should follow the rules in your contracts and local law. Where a rule differs between states or countries, adjust the inputs; the calculator shows its assumptions so you can check them against your own policy. Use the worked example below to check the maths against your own figures.
How the Employee Turnover Cost Calculator works
Replacing an employee costs 30–50% of salary for junior roles and well over 100% for specialists once recruiting, onboarding, lost productivity and knowledge are counted.
Worked example
With the example values (employees who left this year of 12, average annual salary of leavers of $50,000, replacement cost as a share of salary of 50%), the annual cost of turnover is $300,000.00; cost per leaver $25,000.00. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.

Frequently Asked Questions

Which figures do I need?
Employees who left this year, average annual salary of leavers, replacement cost as a share of salary. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
Do the rules differ by location?
Yes. Statutory rates, ceilings and eligibility conditions vary by country and often by state. Adjust the inputs to your jurisdiction and confirm with your payroll provider or labour law adviser.
