In this article I would like to share with you a simple program that I wrote using JavaScript to compute for the mortgage loan of the person. This program is very simple and easy to understand. I hope this program is very useful in your study how to program in JavaScript.

<h3> Mortgage Calculator </h3>

// This is a basic mortgage calculator. It calculates your monthy payment.
var principal_amt = parseFloat(prompt("Enter Principal Amount : "));
var rate = parseFloat(prompt("Enter Yearly Interest Rate : "));
hold_rate=rate;
rate = rate/100/12;
var terms = Number(prompt("Enter Term (years): "));
var hold_terms = terms;
terms = terms * 12;
var amt_solve = (principal_amt * rate) / (1-Math.pow(1+rate, -terms));
var payment_results = amt_solve.toFixed(2);
document.write("<font face='arial' size='4'> ");
document.write("Principal Amount Loaned : Php " + principal_amt + "</font><br>");

document.write("Yearly Interest Rate : " + hold_rate.toFixed(2) + "</font><br>");
document.write("<font face='arial' size='4'> ");
document.write("Terms of Payments (Years) : " + hold_terms + "</font><br>");
document.write("<font face='arial' size='4'> ");
document.write("Amount to be Paid Monthly : Php " + payment_results +".</font>");
