How to Calculate Absenteeism Rate Monthly
Absenteeism is a critical Key Performance Indicator (KPI) for Human Resources departments and business owners. It measures the percentage of scheduled work time that employees miss due to unplanned absence (such as sickness or personal emergencies). High absenteeism can indicate low morale, poor working conditions, or health issues within the workforce.
The Absenteeism Rate Formula
To calculate the monthly absenteeism rate, you need to compare the number of days lost to the total number of days that could have been worked. The standard formula used by the International Standards Organization (ISO) and most HR departments is:
((Total Days Absent) ÷ (Avg Employees × Workdays in Month)) × 100
Here is a breakdown of the variables:
- Total Days Absent: The sum of all days missed by all employees during the month. This usually excludes approved time off like vacations or holidays, focusing instead on sick days and unexcused absences.
- Average Employees: The average number of staff employed during that month.
- Workdays in Month: The number of operational days in the month (usually between 20 and 22 for a standard Monday-Friday schedule).
Example Calculation
Let's look at a practical example. Imagine a company with 50 employees operating in a month with 20 workdays.
If the HR records show that a total of 15 days were missed by various employees due to illness:
- Calculate Total Scheduled Days: 50 employees × 20 days = 1,000 scheduled days.
- Divide Absent Days by Scheduled Days: 15 ÷ 1,000 = 0.015.
- Multiply by 100 to get the percentage: 0.015 × 100 = 1.5%.
In this scenario, the monthly absenteeism rate is 1.5%.
Interpreting the Results
Once you have your rate, what does it mean? While benchmarks vary by industry, general guidelines suggest:
- Below 1.5%: Excellent. Your workforce is healthy and engaged.
- 1.5% – 2.5%: Average. This is a typical range for many industries.
- Above 3%: Concerning. This may indicate burnout, poor management, or viral outbreaks within the office.
- Above 5%: Critical. Immediate action is required to investigate the root causes.
Why Track Monthly?
Calculating this rate on a monthly basis allows HR managers to spot trends quickly. For example, a spike in December might be due to flu season, while a spike in July might indicate dissatisfaction with vacation policies. Consistent monitoring enables proactive management strategies.
Strategies to Reduce Absenteeism
- Implement Wellness Programs: Encourage physical health to reduce sick days.
- Flexible Work Arrangements: allowing remote work can reduce absences due to minor personal issues.
- Return-to-Work Interviews: Briefly discussing an absence when an employee returns can reduce unexcused absences.
- Clear Attendance Policy: Ensure all employees understand the expectations and consequences regarding attendance.
