    NFL Quarterback Rating Formula

    (National Football League)

    a = (((Comp/Att) * 100) -30) / 20

    b = ((TDs/Att) * 100) / 5

    c = (9.5 - ((Int/Att) * 100)) / 4

    d = ((Yards/Att) - 3) / 4

    a, b, c and d can not be greater than 2.375 or less than zero.

    QB Rating = (a + b + c + d) / .06

    AFL Quarterback Rating Formula

    (Arena Football League)

    a = (((Comp/Att) * 100) -30) / 20

    b = ((TDs/Att) *100) / (20/3)

    c = (9.5 - ((Int/Att) * 100)) / 4

    d = ((Yards/Att) - 3) / 4

    a, b, c and d can not be greater than 2.375 or less than zero.

    QB Rating = (a + b + c + d) / .06

    NCAA Quarterback Rating Formula

    (National Collegiate Athletic League)

    a = (Comp/Att) * 100

    b = (TDs/Att) * 100

    c = (Int/Att) * 100

    d = Yards/Att

    QB Rating = a+(3.3*b)-(2*c)+(8.4*d)

    The formula is different for NFL, NCAA, and AFL. Most high schools use NCAA formula. Here is a link to a QB Rating Calculator: http://www.primecomputing.com/

    Use the formula off of wikipedia. The formula has several step to follow so it would be difficult to try and explain them all. THe 4 components the rating is based on are completions, yards, TDs, and INTs.

    Just make sure you use the NFL one.
