Absenteeism Rate Calculator
Calculate the absenteeism rate for your workforce by entering the number of days absent and the total available workdays.
Total Days Absent
Total number of days employees were absent during the period.
Number of Employees
Total number of employees in the workforce.
Workdays in Period
Number of scheduled workdays in the period (e.g. 20 for one month).
Calculate
function absCalc() { var resultDiv = document.getElementById('abs-result');
var daysAbsent = parseFloat(document.getElementById('abs-days-absent').value); var numEmployees = parseFloat(document.getElementById('abs-total-employees').value); var workdays = parseFloat(document.getElementById('abs-workdays').value);
// --- Validation --- if (isNaN(daysAbsent) || isNaN(numEmployees) || isNaN(workdays)) { resultDiv.style.display = 'block'; resultDiv.className = 'calc-result calc-error'; resultDiv.innerHTML = '⚠ Please fill in all three fields.'; return; } if (daysAbsent totalAvailableDays) { resultDiv.style.display = 'block'; resultDiv.className = 'calc-result calc-error'; resultDiv.innerHTML = '⚠ Days absent (' + daysAbsent + ') cannot exceed total available workdays (' + totalAvailableDays + ').'; return; }
// --- Core Formula --- // Absenteeism Rate (%) = (Total Days Absent / (Number of Employees × Workdays in Period)) × 100 var absenteeismRate = (daysAbsent / totalAvailableDays) * 100;
// --- Derived Metrics --- var avgDaysAbsentPerEmployee = daysAbsent / numEmployees; var presentDays = totalAvailableDays - daysAbsent; var attendanceRate = (presentDays / totalAvailableDays) * 100;
// --- Benchmark Classification --- var benchmark = ''; var benchmarkClass = ''; if (absenteeismRate ' + 'Absenteeism Rate' + absenteeismRate.toFixed(2) + '%' + 'Attendance Rate' + attendanceRate.toFixed(2) + '%' + 'Total Available Workdays' + totalAvailableDays.toLocaleString() + ' days' + 'Total Days Present' + presentDays.toLocaleString() + ' days' + 'Avg. Days Absent per Employee' + avgDaysAbsentPerEmployee.toFixed(2) + ' days' + 'Benchmark Status' + benchmark + '' + ''; }
#### Formula
Absenteeism Rate (%) = (Total Days Absent ÷ (Number of Employees × Workdays in Period)) × 100
Attendance Rate (%) = 100 − Absenteeism Rate
Avg. Days Absent per Employee = Total Days Absent ÷ Number of Employees
#### Assumptions & References
- Benchmark thresholds are based on industry guidance from the U.S. Bureau of Labor Statistics (BLS) and CIPD (Chartered Institute of Personnel and Development) absence surveys.
