Quarterback Efficiency Rating

Does anyone out there know specifically how this is calculated. The QER is constantly mentioned on TV during the games and in the papers on the NFL pages…but I have never seen a formula that explains how it is calculated.
Anybody have a clue?

Yup.

Easiest way is to look at the NFL’s own FAQ.

If you want to calculate your favorite QB’s rating, better have a pencil, paper, and calculator on hand… it ain’t quick.

Thanks…

I guess a better question would be who sat down long enough to figure this out!!!
