1. What is Passer Rating?

The Passer Rating (also known as Quarterback Rating) is a measure of the performance of a quarterback in American football. It was adopted by the NFL in 1973 and has since become the official metric for evaluating quarterbacks.

2. How Does the Calculator Work?

The calculator uses the NFL's official passer rating formula:

Where:

• \( comp\% \) — Completion percentage
• \( yds/att \) — Yards per attempt
• \( TD\% \) — Touchdown percentage (TDs per attempt)
• \( INT\% \) — Interception percentage (INTs per attempt)

Explanation: Each component is capped between 0 and 2.375 before being combined. The rating ranges from 0 to 158.3 in the NFL.

3. Importance of Passer Rating

Details: Passer rating is the official metric used by the NFL to evaluate quarterback performance. It provides a comprehensive measure that accounts for completion percentage, yards per attempt, touchdowns, and interceptions.

4. Using the Calculator

Tips: Enter the quarterback's statistics from a game or season. All values must be non-negative, and passing attempts must be greater than zero.
