Rating calculator

Hi everyone. A few of my friends and I play a few games a night a few nigths a week and I thought it'd be kinda cool to start our own little rating race against each other. Question is ... is there a free download of a rating calculator out there anywhere? Didn't find any through google, bing or at download.com. Hasta be one out there though, right?

See how these work out.
