Mortgage Calculator

Mortgage Calculator

A simple mortgage payment calculator, complete with amortization table. This is a very simple web application designed to be quick, easy, and unobtrusive. A general web search for "mortgage calculator" yields results of varying quality. Many are tied to mortgage brokers; at a minimum most are littered with advertisements. Some ask you to input personal information! Some are server-side scripted, meaning they are likely collecting any and all data they can... the list of grievances is endless.

I'm happy to present this simple tool, which has the following features:

  • Simple JavaScript that runs on your browser. This is a statically-generated site; by design I don't have the ability to log any submitted information.
  • Advertisement-free. I pay for this site out of my own pocket as party of my "hobby" budget. Some revenue would be nice, but for now I'm remaining principled.
  • No cookies or other tracking mechanisms. I get nothing out of this, so it would just be more work for me.
  • Simple, open site design. You can do a Ctrl-U to see this page's source, and then in turn you can see the minimal JavaScript used to do nothing more than compute payment info and the amortization table.
