NFL Passer Rating Formula
The NFL Passer Rating is calculated using four components, each of which is capped between 0 and 2.375. The final rating is then derived from the sum of these components.
Let:
- ATT = Passing Attempts
- COMP = Completions
- YDS = Passing Yards
- TD = Touchdowns
- INT = Interceptions
Component Formulas:
Component A (Completion Percentage):
A = ((COMP / ATT) - 0.3) × 5
(Capped between 0 and 2.375)
Component B (Yards Per Attempt):
B = ((YDS / ATT) - 3) × 0.25
(Capped between 0 and 2.375)
Component C (Touchdown Percentage):
C = (TD / ATT) × 20
(Capped between 0 and 2.375)
Component D (Interception Percentage):
D = 2.375 - ((INT / ATT) × 25)
(Capped between 0 and 2.375)
Final Passer Rating Calculation:
Passer Rating = ((A + B + C + D) / 6) × 100
