Enter HR staff in full-time equivalents and the number of employees to see the HR to employee ratio, HR staff per 100 employees and employees served per HR person.
The HR to employee ratio compares the size of the HR function with the workforce it supports. It is usually stated as HR staff per 100 employees, or as one HR person for every so many employees.
Use it to track your own organisation over time, or to test a hiring plan before headcount changes. It says nothing on its own about whether HR is doing a good job.
Enter your figures, then press Calculate
Your 2 inputs become a full breakdown, with every step of the working shown beneath the headline figures.
Two counts and one division. The care goes into deciding who counts as HR and who counts as an employee, because that choice moves the answer more than anything else.
HR staff per 100 employees = HR FTE ÷ Employees × 100; Employees per HR FTE = Employees ÷ HR FTE
Decide which roles count: generalists, payroll, recruitment, learning, HR operations. Roles outsourced to a vendor are not in the count, which is one reason ratios differ between organisations.
Add part-time and shared roles as fractions of a full-time role, so one person splitting time between HR and admin counts only for the HR share.
Use headcount on a stated date, and say whether contract and fixed-term staff are included. Keep the definition the same each time you measure.
Divide HR FTE by employees for the per-100 figure, and employees by HR FTE for the one-to-many form.
What this does not include
Asked often enough about this calculation to be worth answering beside it.
Divide the number of HR staff, in full-time equivalents, by the total number of employees and multiply by 100 to get HR staff per 100 employees. Dividing employees by HR staff gives the one-to-many form.
There is no single right figure. It depends on how much work is automated or outsourced, how many locations and states you operate in, and how complex your workforce is. Track your own ratio over time and read it alongside service measures.
If payroll sits in HR in your organisation, count it. If it sits in finance, leave it out. What matters is applying the same definition each time.
Often, because some HR work does not grow in step with headcount. But new locations, new states or a shift to more complex hiring can push it the other way.
A calculator applies a rule to figures you type in. A payroll run applies it to your actual employee record, your locations and your verified declarations, which is where Professional Tax, LWF and TDS also resolve.
