The full form of GST is Goods and Services Tax. Today I will tell you how to create a gst calculator by javascript code. First of all, you create an html form, add 3 text field and 1 button. For this you can see in the example mentioned below.

<html>
<head>
<title>How to Create GST Calculator using Javascript</title>
</head>
<body>
<div>
<label for="price">Price (before GST): </label>
<input id="price" type="number" value="1" />
</div>
<div>
<label for="gst">GST rate (%): </label>
<input id="gst" type="number" value="0.6" />
</div>
<div>
<button onclick="inpChange()">Calculate</button>
</div>
<div>
<label for="priceGst">Price (GST inclusive) : </label>
<input id="priceGst" type="number" readonly />
</div>
</body>
</html>

Then after that you write script code for gst calculation, for example you can see the script code given below.

<script>
priceEle = document.getElementById("price");
gstEle = document.getElementById("gst");
priceGstEle = document.getElementById("priceGst");
function calculateGst(price, tax) {
return (price * tax/100) + price;
} 
function inpChange() {
if(!isNaN(priceEle.value) && !isNaN(gstEle.value)) {
price = Number(priceEle.value);
gst = Number(gstEle.value);
priceGstEle.value = calculateGst(price, gst).toFixed(3);
}
}
inpChange();
</script>

You can add whole code to gst-calculator.html by creating a file. gst-calculator.html
