What Is QB Passer Rating?
The QB Passer Rating is a statistical formula used to measure the overall performance of a quarterback based on passing efficiency.
It considers four main performance areas:
- Completion accuracy
- Passing yard efficiency
- Touchdown performance
- Interception control
Each component is calculated separately and then combined to produce a final rating.
The rating scale typically ranges from 0 to 158.3 in the NFL system, where higher values indicate better performance.
How the QB Passer Rating Calculator Works
The calculator takes five inputs:
- Passing Attempts (ATT)
- Completions (COMP)
- Passing Yards
- Touchdowns (TD)
- Interceptions (INT)
Then it breaks performance into four components:
- Completion Rate Component
- Yards Component
- Touchdown Component
- Interception Component
Finally, these values are combined to produce the final passer rating.

QB Passer Rating Formula Explained
The NFL passer rating system is based on four mathematical components.
1. Completion Rate Component
a=(attemptscompletions−0.3)×5
This measures passing accuracy.
- Higher completion percentage = better score
- Lower accuracy = reduced rating
2. Yards Per Attempt Component
b=(attemptsyards−3)×0.25
This measures how many yards a quarterback gains per pass attempt.
- Deep passing improves rating
- Short passes lower efficiency score
3. Touchdown Component
c=attemptstouchdowns×20
This rewards quarterbacks for scoring passes.
- More touchdowns = higher rating
4. Interception Component
d=2.375−(attemptsinterceptions×25)
This penalizes interceptions.
- Fewer interceptions = higher score
- More interceptions = lower rating
Final Passer Rating Formula
After calculating all four components:
Rating=6a+b+c+d×100
This produces the final QB Passer Rating.
Important Rules in Calculation
Each component is limited between:
0 to 2.375This ensures balanced performance evaluation and prevents extreme values from distorting results.
