How to calculate your absenteeism rate (free formula and calculator).

Your absenteeism rate is the share of available work time lost to absence. One formula gives you the number. Use the calculator below, then read what a healthy figure looks like.

The formula

Absenteeism rate = (absent days ÷ available work days) × 100

Available work days = number of employees × work days in the period.

Absenteeism rate

3.5%

Average absent days per employee

2.3

A quarter is about 65 work days per full-time employee. A full year is about 260. Adjust the period to match your absent-day total.

A worked example

A 30-person team works one quarter, about 65 work days each. This gives 1,950 available work days. The team took 68 absent days in the quarter.

68 ÷ 1,950 = 0.0349. Multiply by 100 for an absenteeism rate of 3.5 percent. The rate works out to about 2.3 absent days per employee for the quarter, or roughly 9 days a year. Close to the Australian average (8.8 days).¹

What counts as a healthy rate

Treat these bands as a guide, not a verdict. Sector, season, and a single long illness all move the number. The trend over time tells you more than any single figure.

Under 2%

Low. Healthy for most office teams. Watch for presenteeism hiding real illness.

2% to 4%

Typical. The Australian average sits near the top of this band.

Above 4%

Worth investigating. Look for patterns by person, team, and weekday before you act.

The rate tells you the size of the problem. The shape tells you the cause. Pair this with day-of-week pattern analysis and a Bradford Factor view of frequency.
