Earnings Credit Rate Calculator
This calculator helps you determine the effective Earnings Credit Rate (ECR) based on your account's average ledger balance and the earnings credit you receive. Understanding your ECR is crucial for evaluating the value of banking services and identifying potential cost savings.
function calculateECR() {
var ledgerBalance = parseFloat(document.getElementById("ledgerBalance").value);
var earningsCredit = parseFloat(document.getElementById("earningsCredit").value);
var resultDiv = document.getElementById("result");
resultDiv.innerHTML = ""; // Clear previous results
if (isNaN(ledgerBalance) || isNaN(earningsCredit)) {
resultDiv.innerHTML = "Please enter valid numbers for both fields.";
return;
}
if (ledgerBalance <= 0) {
resultDiv.innerHTML = "Average Ledger Balance must be greater than zero.";
return;
}
// Calculate the Earnings Credit Rate (ECR) as a decimal
// ECR = (Earnings Credit Received / Average Ledger Balance) * 100
var ecrDecimal = earningsCredit / ledgerBalance;
var ecrPercentage = ecrDecimal * 100;
resultDiv.innerHTML = "
Result:
";
resultDiv.innerHTML += "Your calculated Earnings Credit Rate (ECR) is:
" + ecrPercentage.toFixed(4) + "%";
resultDiv.innerHTML += "This means for every $1,000,000 in your average ledger balance, you received an equivalent of " + ecrPercentage.toFixed(4) + "% in earnings credit.";
