Understanding Annual Growth Rate (AGR)

The Annual Growth Rate (AGR) is a fundamental metric used to measure the percentage change in a value over a one-year period. It's widely applied across various fields, including finance, economics, business, and population studies, to understand trends and performance.

How to Calculate AGR:

The formula for calculating the Annual Growth Rate is straightforward:

AGR = ((Ending Value – Beginning Value) / Beginning Value) * 100

  • Ending Value: This is the value of the item at the end of the one-year period.
  • Beginning Value: This is the value of the item at the beginning of the one-year period.

A positive AGR indicates growth, while a negative AGR signifies a decline. For example, if a company's revenue grew from $1,000,000 to $1,200,000 in a year, its AGR would be 20%.

function calculateAGR() { var beginningValue = parseFloat(document.getElementById("beginningValue").value); var endingValue = parseFloat(document.getElementById("endingValue").value); var resultDiv = document.getElementById("result"); if (isNaN(beginningValue) || isNaN(endingValue)) { resultDiv.textContent = "Please enter valid numbers for both values."; return; } if (beginningValue === 0) { resultDiv.textContent = "Beginning value cannot be zero for AGR calculation."; return; } var growthRate = ((endingValue – beginningValue) / beginningValue) * 100; if (growthRate >= 0) { resultDiv.textContent = "Annual Growth Rate: " + growthRate.toFixed(2) + "%"; } else { resultDiv.textContent = "Annual Growth Rate: " + growthRate.toFixed(2) + "% (Decline)"; } }
