Have a go at this crappy morgage calculator. Insofaras mortage calculators go, it’s middle of the road. It doesn’t allow for being an investor, which renders it useless to me – I have a substaintial investment income (only matched by my substaintial interest expense), and I’m not trading up from my current house.

But my biggest gripe is how the calculator has been “designed” to only work if you enter a valid, live email address. So this thing turns out to be a marketting tool, not a calculator per se. The address of me@example.com doesn’t work. If you enter an email address that isn’t live, it doesn’t give an error message – it barfs with an ASP error when sending the email fails. WTF? How is J Random User meant to figure that one out? Thankfully, it hands over the results (for what they’re worth) because jobs@google.com is a valid email address. Sorry about that, Google.
