The Annual Average Growth Rate (AAGR) is a simple way to calculate the average yearly increase of a value over a specific period. It's particularly useful for understanding trends in business, finance, or any data that changes over time. Unlike the Compound Annual Growth Rate (CAGR), AAGR doesn't account for compounding, making it a more straightforward, though less precise, measure for volatile data.
function calculateAAGR() {
var startValue = parseFloat(document.getElementById("startValue").value);
var endValue = parseFloat(document.getElementById("endValue").value);
var years = parseFloat(document.getElementById("years").value);
var resultDiv = document.getElementById("result");
if (isNaN(startValue) || isNaN(endValue) || isNaN(years) || startValue <= 0 || years <= 0) {
resultDiv.innerHTML = "Please enter valid positive numbers for all fields.";
return;
}
var totalGrowth = endValue – startValue;
var averageGrowth = totalGrowth / years;
var aagr = (averageGrowth / startValue) * 100;
if (isNaN(aagr)) {
resultDiv.innerHTML = "Calculation error. Please check your inputs.";
} else {
resultDiv.innerHTML = "
