Pro Rata Share Calculator
A pro rata share calculation is used to distribute a portion of something proportionally among different parties. The term "pro rata" itself is Latin for "in proportion." This is commonly used in finance, law, and other areas where a total amount needs to be divided fairly based on individual ownership, contribution, or entitlement.
The basic principle is that each party receives or pays an amount that is directly proportional to their share of the whole. For example, if a company has multiple shareholders, dividends might be distributed pro rata based on the number of shares each person owns. Similarly, if an expense is to be shared among partners, it might be divided pro rata based on their agreed-upon ownership percentages.
function calculateProRataShare() {
var totalAmountInput = document.getElementById("totalAmount");
var yourPortionInput = document.getElementById("yourPortion");
var resultDiv = document.getElementById("result");
var totalAmount = parseFloat(totalAmountInput.value);
var yourPortion = parseFloat(yourPortionInput.value);
if (isNaN(totalAmount) || isNaN(yourPortion)) {
resultDiv.innerHTML = "Please enter valid numbers for all fields.";
return;
}
if (yourPortion 1) {
resultDiv.innerHTML = "Your portion must be between 0 and 1 (e.g., 0.25 for 25%).";
return;
}
var proRataShare = totalAmount * yourPortion;
resultDiv.innerHTML = "Your Pro Rata Share is: " + proRataShare.toFixed(2);
