We’re working on adding a few extra features like a mortgage amortization schedule, some help boxes, and the ability save your calculations. Stay tuned or subscribe to the feed to get updates on when these things roll out.
Let us know if you would like to get the frograte mortgage calculator on your own website. If we see that there’s enough interest in this, we’ll put together some free copy-and-paste code that will let you run a smaller version of this anywhere on your site so your users can run rates as fast as they can type. Drop us a note or give us your email address so we can update you (if and) when this service rolls out.
