Add up costs script

[businessbytes]

I am trying to locate a script that will add up the start up costs for a business and/or any add up script that will allow me to enter subject matter and visitors provide input data.

If anyone could help I would greatly appreciate it.

Such scripts are usually tied to the page HTML code like form input names. I doubt you will easily find something generic that will suit all your needs.
The script is not that hard to write.
Use onchange event of form input elements to call a functions that polls all the inputs you need to sum and writes the result to a dedicated element.
