How do you calculate the absenteeism rate?
Divide the number of unplanned absence days by the total number of scheduled working days, then multiply by 100. For example, 200 employees with 250 working days each have 50,000 scheduled days. If they are absent for 1,200 days in a year, the absenteeism rate is 2.4%.

- Absenteeism rate = absence days ÷ (employees × working days) × 100.
- Count unplanned absence only; leave out vacation and planned leave.
- Direct cost = absence days × daily pay, plus any extra cost of cover.
- Lost output and strain on colleagues are not in the direct cost, so the real cost is higher.
- Look at patterns by team and over time, not only the company average.

Absenteeism rate
–
Absenteeism rate = absence days ÷ (employees × working days) × 100. Direct cost = absence days × (salary ÷ working days) × (1 + cover cost %). Lost output, slower service and the strain on colleagues who cover are not included, so the full cost is usually higher.
The formulas, step by step.
| Measure | Formula | Example |
|---|---|---|
| Scheduled working days | Employees × working days per employee | 200 × 250 = 50,000 |
| Absenteeism rate | Absence days ÷ scheduled days × 100 | 1,200 ÷ 50,000 × 100 = 2.4% |
| Daily pay | Annual salary ÷ working days | 60,000 ÷ 250 = 240 |
| Direct cost | Absence days × daily pay × (1 + cover cost %) | 1,200 × 240 = 288,000 |
What to count as absence.
Use unplanned absence: sickness, unauthorized absence and other days people were scheduled to work but did not. Leave out vacation, public holidays, parental leave and other planned leave. Be consistent: if you count half days, count them everywhere, and use the same definition each year so trends mean something.
Reading the patterns.
A rising absence rate in one team is a signal, not a verdict. Frequent short absences can point to stress, low morale or problems with a manager. Long absences more often reflect illness or burnout. Compare teams with similar work, look at trends over several quarters, and pair absence data with survey results on workload and energy before drawing conclusions. See absenteeism: causes and what to do.
What to do about it.
Talk with people when they come back, without blame, to understand what got in the way. Look at workload and staffing in teams where absence is rising. Make sure sick people feel able to stay home, so they do not spread illness or recover more slowly. And measure the earlier signals, such as energy, recovery and focus, so you can act before people are off sick. Capacity is the energy, recovery, focus and resilience a person has available to sustain performance.
thrive at work measures engagement (purpose, leadership, connection, growth) and capacity (energy, recovery, focus, resilience) in one anonymous assessment: see how the assessment works.
Most engagement problems show up first as falling energy, recovery and focus. thrive at work is a workforce performance platform: an employee engagement platform that also measures capacity to perform, so you can see strain by team before it turns into absence or resignations.
