NFL(National Football League) and CFL(Canadian Football League) QB formula
a = ((completions ÷ passing attempts) - 0.3) × 5
b = ((passing yards ÷ passing attempts) - 3) × 0.25
c = (touchdown passes ÷ passing attempts) × 20
d = 2.375 - ((interceptions ÷ passing attempts) × 25)
If any of a, b, c, or d are less than 0, then they calculated as 0.
If any of a,b,c, or d are more than 2.375, then they are calculated as 2.375.
Passer Rating = ((a + b + c + d) ÷ 6) × 100
| A perfect passer rating (158.3) requires at least | A minimum rating (0.0) requires at best |
