Understanding customer churn is vital for any business. Customer churn rate, also known as customer attrition rate, measures the percentage of customers who stop using a company's product or service during a given period. A high churn rate can significantly impact revenue and growth. This calculator helps you easily compute your churn rate based on the number of customers you started with, the number of new customers acquired, and the number of customers lost during a specific period.
function calculateChurnRate() {
var customersBeginning = parseFloat(document.getElementById("customersBeginningPeriod").value);
var customersEnd = parseFloat(document.getElementById("customersEndPeriod").value);
var newCustomers = parseFloat(document.getElementById("newCustomersAcquired").value);
var resultDiv = document.getElementById("result");
resultDiv.innerHTML = ""; // Clear previous results
if (isNaN(customersBeginning) || isNaN(customersEnd) || isNaN(newCustomers) || customersBeginning < 0 || customersEnd < 0 || newCustomers loss and start value
if (customersLost < 0) {
customersLost = 0;
}
var churnRate = (customersLost / customersBeginning) * 100;
resultDiv.innerHTML = "Customer Churn Rate: " + churnRate.toFixed(2) + "%";
}
