Attrition rate, often referred to as churn rate, is a key metric for businesses to understand how many customers or employees they are losing over a specific period. A high attrition rate can indicate underlying issues with product, service, or employee satisfaction. Calculating this rate helps businesses identify problems and implement strategies to improve retention.
function calculateAttritionRate() {
var employeesAtStart = parseFloat(document.getElementById("employeesAtStart").value);
var employeesAtEnd = parseFloat(document.getElementById("employeesAtEnd").value);
var employeesHired = parseFloat(document.getElementById("employeesHired").value);
var resultDiv = document.getElementById("result");
resultDiv.innerHTML = ""; // Clear previous results
if (isNaN(employeesAtStart) || isNaN(employeesAtEnd) || isNaN(employeesHired) ||
employeesAtStart < 0 || employeesAtEnd < 0 || employeesHired 0 or hires > 0, this scenario is unusual for attrition calculation.
// For simplicity and common use cases, we'll assume employeesAtStart > 0 for the average calculation.
// A more robust calculation might handle these edge cases differently depending on business context.
var averageEmployees = (employeesAtStart + employeesAtEnd) / 2;
var attritionRate = 0;
if (averageEmployees > 0) {
attritionRate = (departures / averageEmployees) * 100;
} else if (employeesAtStart === 0 && employeesAtEnd === 0 && employeesHired === 0) {
attritionRate = 0; // No employees, no churn.
} else {
// This case might represent starting with 0 employees and ending with some, or hires without a starting base.
// The standard formula's average becomes problematic.
// In such specific scenarios, context dictates how to interpret.
// For this calculator, we'll indicate an issue or assume 0% if no departures are possible from a zero base.
if (departures === 0) {
attritionRate = 0;
} else {
resultDiv.innerHTML = "Cannot calculate average employees for attrition rate with these inputs.";
return;
}
}
resultDiv.innerHTML = "Number of Departures: " + departures + "" +
"Average Number of Employees: " + averageEmployees.toFixed(2) + "" +
"Attrition Rate: " + attritionRate.toFixed(2) + "%";
