A capped, weighted formula
Each of the four inputs is bounded so no single stat dominates. That is why even a flawless line tops out at 158.3 rather than rising without limit.
Frequently asked questions
How is NFL passer rating calculated?
From four components — completion percentage, yards per attempt, touchdown rate and interception rate — each capped between 0 and 2.375, then combined and scaled.
What is a perfect passer rating?
The maximum NFL passer rating is 158.3, achieved by maxing out all four components. Anything over 100 is considered an excellent performance.
