Whether it stems from external events, work-related illness, or a lack of engagement, absenteeism is a major challenge for organizations. It can significantly impact productivity and disrupt day-to-day operations. Rising absenteeism can also negatively affect employees’ mental health, which must remain a central concern for employers.
However, by introducing indicators such as the absenteeism rate and studying its underlying causes, companies can develop strategies to manage and reduce absences. Let’s explore what absenteeism rate is, how to calculate it, and how to use it effectively.
What Do We Mean by Absenteeism Rate?
Absenteeism refers to the fact that an employee is absent from work (including remote work) when they are expected to be present. Absenteeism generally involves repeated or prolonged, and often unplanned absences.
It can be further categorized by criteria such as short-term vs. long-term absences, or whether an absence is justified (e.g., sick leave, work accident, family leave) or unjustified.
The absenteeism rate is simply the measure of absenteeism—evaluating the proportion of employees absent in relation to total staff, and/or the share of working hours or days lost compared to what should normally be worked across the company.
How to Calculate the Absenteeism Rate
As with many HR metrics, quantifying absenteeism helps organizations understand its causes and implement effective prevention and management measures.
Formulas to Calculate Absenteeism
The most common calculation is:
Absenteeism Rate = (Total number of days absent over a period ÷ Total number of working days) × 100
Absenteeism can also be calculated using hours rather than days. In this case:
Absenteeism Rate = (Days absent × hours per day) ÷ (Working days × hours per day × number of employees) × 100
This is the most commonly used formula in HR surveys and internal reporting.
For example: an organization employs 30 people, each working 35 hours per week (7 hours per day) over 22 working days in a month. If, over the first quarter, there were a total of 45 days of absence:
(45 × 7) ÷ (22 × 7 × 30) × 100 = 6.82
The absenteeism rate for the quarter would be around 6.8%.
This calculation can be applied at company level, by department, or over different periods of time for comparison.
Which Absences Are Included?
Not all absences should be included in absenteeism calculations. For instance, planned absences such as paid vacation, maternity/paternity leave, or training are excluded. In France, strike days are also not counted.
Absenteeism typically covers:
- Justified but unpredictable absences, such as sick leave, occupational accidents, professional illness, or family emergency leave.
- Unjustified absences, which are considered professional misconduct, such as missing work without approval or without a valid excuse.
Why Calculate the Absenteeism Rate?
Absenteeism can have serious repercussions for companies: reduced productivity and profitability, higher operating costs, deterioration of workplace climate, increased turnover, and damage to employer brand and reputation.
But is absenteeism the real cause, or just a symptom? Calculating the absenteeism rate helps answer that question:
- A low rate may indicate that issues are not linked to absenteeism but perhaps to market conditions, low engagement, or a weak business strategy. Or, it may reflect a healthy, engaged workforce.
- A high rate may signal serious dysfunctions that must be addressed to limit costs and negative ripple effects across teams and operations.
Another reason to calculate absenteeism is that it is a simple, accessible indicator requiring only a few data points. Integrated into a dashboard, it allows for quick and meaningful comparisons across timeframes, teams, and benchmarks.
How to Analyze the Absenteeism Rate
Like any indicator, data is only useful when analyzed. Monitoring absenteeism rate over time allows organizations to understand trends and evaluate the impact of measures implemented.
- Compare with national averages: for example, in France, the AG2R La Mondiale barometer (2023) reports absenteeism rates between 5.5% and 7% from 2019 to 2022. A rate below 5% is excellent; above 9–10% signals a critical issue.
- Analyze by department or team: if one department shows a higher rate, factors may include management style, workload, or scheduling practices.
- Look at recurring seasonal peaks: if absenteeism consistently rises in certain periods, anticipate and rebalance workloads in advance.
Keep in mind: zero absenteeism is neither realistic nor desirable. The goal is not elimination, but prevention, anticipation, and management.
