Passer Rating Calculator

Passer Rating Formula:

\[ PR = \left[ \frac{ \left( \frac{C}{A} - 0.3 \right) \times 5 + \left( \frac{Y}{A} - 3 \right) \times 0.25 + \left( \frac{T}{A} \right) \times 20 + 2.375 - \left( \frac{I}{A} \times 25 \right) }{6} \right] \times 100 \]

1. What is the Passer Rating Formula?

The Passer Rating (also known as Quarterback Rating) is a measure of the performance of quarterbacks in American football. It was adopted by the NFL in 1973 and considers completions, attempts, yards, touchdowns, and interceptions to evaluate quarterback efficiency.

2. How Does the Calculator Work?

The calculator uses the NFL Passer Rating formula:

Where:

\( C \) — Completions
\( A \) — Attempts
\( Y \) — Passing Yards
\( T \) — Touchdown Passes
\( I \) — Interceptions

Explanation: Each component is calculated separately and capped between 0 and 2.375 before being combined and scaled to produce the final rating.

3. Importance of Passer Rating

Details: Passer rating is the official quarterback statistic used by the NFL to evaluate quarterback performance. It provides a comprehensive measure that balances completion percentage, yards per attempt, touchdown percentage, and interception percentage.

4. Using the Calculator

Tips: Enter the quarterback's statistics from a game or season. All values must be valid (attempts must be greater than 0, and other values cannot exceed attempts where applicable).

5. Frequently Asked Questions (FAQ)

Q1: What is a perfect passer rating?
A: The maximum possible passer rating is 158.3. This requires exceptional performance across all statistical categories.

Q2: What is considered a good passer rating?
A: Generally, a rating above 90 is good, above 100 is excellent, and above 110 is exceptional. The NFL average typically ranges between 80-90.

Q3: How does passer rating compare to newer metrics like QBR?
A: While passer rating is the official NFL statistic, ESPN's Total QBR attempts to account for situational factors and rushing contributions that passer rating ignores.

Q4: Can passer rating be negative?
A: No, the minimum passer rating is 0 due to the capping of components at 0.

Q5: Why are the components capped at 2.375?
A: The capping prevents any single component from disproportionately influencing the final rating and maintains balance across the four statistical categories.
