I have the beginings of a website using wordpress and i need to add in an online calculator. The calculator needed is similar to a mortgage calculator but with some extra fields to quantify savings an a mortgage if additional payments are added.
I have an example that is written in excel 2007 that we have been using but want to add this to a username and password protected page on our web site. the calculator should be able to calculate the savings on a given mortgage and display a result along with a graph of the savings. the results should be able to be printed as a PDF which can then be printed out or saved to a file. the calculator should only be able to be used online and not downloadable. I have more information and an example if you can assist. Thanks Alan
