Turnover rate

The turnover rate is the share of employees who left the company during a period, expressed as a percentage. The standard formula divides the number of departures in the period by the average headcount for that same period and multiplies by 100. The word average matters: using the headcount on the last day of the period distorts the result in any company that is growing or shrinking.

One number on its own says very little. A rate of 18% is healthy in retail and alarming in engineering, and a company average can hide a single team losing half its people.

The cuts that make the number useful

Before drawing conclusions, split the figure:

• Voluntary and involuntary. Resignations and dismissals are different problems with different owners.
• Regrettable and non-regrettable. Losing a strong performer is not the same event as a planned exit, even though both count as one departure.
• Early turnover. Departures in the first year point at hiring and onboarding rather than at management.
• By team, manager and location. This is where the real cause usually appears.
• Average tenure of leavers. A stable rate with falling tenure means people are leaving sooner each year.

How it differs from neighbouring metrics

Employee turnover is the phenomenon; the turnover rate is its measurement. Attrition usually refers to positions that are not refilled, so headcount falls with it. The retention rate looks at the same reality from the other side, counting who stayed, and the two do not simply add up to 100% because retention is normally calculated on people present at the start of the period.

Mistakes that make the number meaningless

Four errors account for most unusable turnover reporting:

• Comparing your figure with an industry benchmark calculated on a different definition.
• Counting internal transfers and promotions as departures, which inflates the rate and hides genuine headcount movement.
• Including seasonal and temporary staff in the same figure as permanent employees.
• Tracking the rate but never asking why, so the exit interview data and the number are never in the same conversation.

How PeopleForce calculates it

The termination breakdown report in HR analytics builds the figure month by month: for each month it takes the employees terminated in that month and divides them by the number of people employed during it, giving a percentage to one decimal place. Over the selected period it also shows total departures, the average number of departures per month, and the average tenure of the people who left, which is the pattern most companies miss.

The same report filters by division, department, location, position, employment type, seniority, job profile, manager, and by termination type and reason, so you can move from the company figure to the specific team or manager without exporting anything. When you do need the raw data, the report exports to XLSX or CSV. For the causes behind the number, Pulse adds engagement and eNPS trends per department, which usually move before the turnover rate does.
