Are you trying to buy a house? Well, if so, this tells you how much you'll have to pay each month for it, factoring in taxes and loan terms, so you can immediately find out if a house or condo is just too bonkers for you.
Just a calculator for the US Federal Per Diem. I wrote one for Virginia, and was asked to do one for the GSA rates, so I did some rethinking and put it on this site. Business Offices loved the Virginia one to the extent that some require a printout from my site for travel reimbursements. The About page tells you a bit more and links to my personal site where I've written about it in even more detail.
As a fairly ardent Democratic supporter and political junkie, the unrepentant mistruths of Paul Ryan's GOP convention speech annoyed me a great deal. As a distance runner, Paul Ryan shaving over an hour off of his actual marathon time, and putting himself into the much-envied group of runners who've achieved a sub-3 hour marathon, outright angered me. And as a web nerd, I figured I could at least help others understand what their Paul Ryan marathon speeds would be -- so I built a quick calculator to do just that. Enjoy!
