The main thing in this program is the formula of the GST Calculation. Here we put both back and front calculation for the GST. If is it GST Exclusive then GST over the amount and if is it GST Inclusive then GST in the amount.

The formula of GST Exclusive (Front Calculation)-


The formula of GST Inclusive (Back Calculation)-

inclusive=amount*100/(100 + gst_percent);

Back to coding, To complete this program with debugging free code you have to create only one file (index.php) because we use the bootstrap framework to style our CSS. And we also post data on the same page using the PHP function “isset($_POST[‘submit’]))” that only shows data ones it’s submitted.


Create a PHP file named ‘index.php‘ and put those codes given below.
