This calculator helps you determine the coupon rate of a bond, which is the annual interest rate paid on the bond's face value. Understanding the coupon rate is crucial for bond investors as it directly influences the income they receive from their investment.
function calculateCouponRate() {
var annualInterestPayment = parseFloat(document.getElementById("annualInterestPayment").value);
var faceValue = parseFloat(document.getElementById("faceValue").value);
var resultDiv = document.getElementById("result");
resultDiv.innerHTML = ""; // Clear previous results
if (isNaN(annualInterestPayment) || isNaN(faceValue)) {
resultDiv.innerHTML = "Please enter valid numbers for all fields.";
return;
}
if (faceValue <= 0) {
resultDiv.innerHTML = "Face Value must be greater than zero.";
return;
}
var couponRate = (annualInterestPayment / faceValue) * 100;
resultDiv.innerHTML = "The calculated Coupon Rate is: " + couponRate.toFixed(2) + "%";
