The formula
a = (CMP ÷ ATT − 0.3) × 5 b = (YDS ÷ ATT − 3) × 0.25 c = TD ÷ ATT × 20 d = 2.375 − INT ÷ ATT × 25 rating = (a + b + c + d) ÷ 6 × 100
Each component is held between 0 and 2.375, which is why the rating runs from 0 to 158.3. College football uses a different formula.
What to watch out for
Yards may be negative for a very poor game, and the cap still holds that component at zero.
