How is employee turnover rate calculated?

Divide the number of separations across 12 months by your average headcount, then multiply by 100. Average headcount is your headcount 12 months ago plus your headcount now, divided by two. For example, 12 separations over a year against an average headcount of 100 gives a 12% turnover rate. Use a full 12 months, because the benchmark you are comparing against is annual.

Where Compono fits

A turnover rate tells you people are leaving. It does not tell you why, or who is at risk next. Most HR systems track the exits and stop there, leaving the people-insight side of the question unanswered. Compono Engage adds the culture and engagement data that shows you where disengagement is building before it turns into a resignation, so you act early instead of counting losses. Compono holds a 4.8 out of 5 rating on Capterra and grew 20% year on year against a 9.8% industry average.

How it's calculated

Turnover rate is the number of separations across 12 months divided by your average headcount, then multiplied by 100. Average headcount is your headcount 12 months ago plus your headcount now, divided by two. The period matters: this tool uses a rolling 12 months because the benchmark is an annual rate, so entering a quarter's separations would produce a quarterly rate that is not comparable. If you only have a shorter window, annualise it first (a quarter's separations multiplied by four is a rough guide, though it ignores seasonality). The Australian average is about 16% (AHRI), and it shifts by size: around 11% for small organisations, 15% for medium, and 21% for large.

Common questions

What is a good employee turnover rate in Australia?

The Australian average is about 16% (AHRI). Smaller organisations tend to sit near 11%, medium around 15%, and large around 21%. Below your size benchmark is healthy. Well above it is worth investigating.

Should I include all departures?

This calculator uses total separations, both voluntary and involuntary, for an overall rate. If you want to focus on retention specifically, run it again using only voluntary resignations, since those are the exits you have the most influence over.

What is the difference between turnover and attrition?

Turnover usually counts every departure, including roles you backfill. Attrition often refers to departures where the role is not replaced. This calculator measures turnover, the broader of the two.
