What code do you have so far?

This should be posted in the PHP forum, but don't double post. A moderator will probably move it soon.

Look into the use of Javascript to process data on the client side, or if you really want to get creative, AJAX.

Looks indeed like the perfect problem to tackle with an Ajax solution. That way you can, after the user has inputted some field(s), go to the server database, get the data and display it on the screen. All without screen refreshes.

But, as acoder put to you in an earlier post: "What code do you have so far?". Show it and we will see where we can assist you.

you can use the following code for a running total. customize it according to ur requirements.

function getTotalBurn()
f = document.form1;
superficial = parseFloat(f.a.value) + parseFloat(f.b.value)
f.c.value = superficial.toFixed(2)

<form id="form1" name="form1" method="post" action="" onkeyup="getTotalBurn()">
1st Number
<input type="text" name="a" size="10" />
2nd Number
<input type="text" name="b" size="10" />
<input type="text" name="c" value="0" size="10" />
