php automatically update text areas and such?

This is a complicated question and i know the answer will be equally as vague, but bare with me..

I have a program i'm building using html PHP and "spry tabs" via dreamweaver..

the point of this system is to give customers quotes. Our company gets people out of debt.

so for example, you'd put in their creditor information, the amount of debt they have with each creditor, and it will show the monthly payments they need to make, how much we can save them, and several other things.

the softare is not complete BUT. The way it works now is that when you update information, you have to hit UPDATE and it saves it to the database..

what i would like is for it to automatically do the math as soon as the information is entered. and then hit update to send it TO the database as updated information..

in other words, if we change the amount of months that they wish to be in the program, it will automatically account for that and change the fee structure etc etc.

i know that AJAX will do this, and i know that ASP.NET will do this.

i can DO IT in asp.net, but i don't know AJAX, Javascript, or whatever else that i could make use of to do this.

this is where the question gets vague..

HOW DO I DO THIS?

is there anything online existing that does math similar to this that i can take from study and alter to my needs?

what i need is something like this (assuming these are text boxes)

creditor 1 = 1000
creditor 2 = 2000
so on

===total debt = 3000 (automatically renders)

15% service fee = 450 (automatically renders)

etc... there are about 50 other things it NEEDS to do, but maybe getting that much will help me with the rest of it.

like i said i don't know javascript, so if you provide me with example code, please provide me with something that i can add math to simply.

thanks in advance
