Passer Rating Calculator

Passer Rating Formula:

\[ Rating = \frac{(8.4 \times \frac{yds}{att}) + (330 \times \frac{TD}{att}) + (100 \times \frac{comp}{att}) - (200 \times \frac{INT}{att})}{6} \times 100 \]

1. What is Passer Rating?

Passer rating (also known as quarterback rating) is a measure of the performance of quarterbacks in American football. It is calculated using a player's passing attempts, completions, yards, touchdowns, and interceptions.

2. How Does the Calculator Work?

The calculator uses the NFL passer rating formula:

\[ Rating = \frac{(8.4 \times \frac{yds}{att}) + (330 \times \frac{TD}{att}) + (100 \times \frac{comp}{att}) - (200 \times \frac{INT}{att})}{6} \times 100 \]

Where:

\( comp \) — Pass completions
\( att \) — Pass attempts
\( yds \) — Passing yards
\( TD \) — Touchdown passes
\( INT \) — Interceptions

Explanation: The formula combines four components (completion percentage, yards per attempt, touchdowns per attempt, and interceptions per attempt) into one rating.

3. Importance of Passer Rating

Details: Passer rating is used to evaluate quarterback performance, compare players, and assess game strategy. It's one of the primary statistics used in football analytics.

4. Using the Calculator

Tips: Enter all required statistics from a game or season. Attempts must be greater than zero. The perfect passer rating is 158.3.

5. Frequently Asked Questions (FAQ)

Q1: What is a good passer rating?
A: In the NFL, a rating above 90 is considered good, above 100 is excellent, and the maximum possible is 158.3.

Q2: Why is the maximum 158.3?
A: The formula's design caps each component at 2.375, which when combined gives a maximum of 158.3.

Q3: How does college passer rating differ?
A: College football uses a simpler formula without the 158.3 cap, so ratings can exceed that number.

Q4: What are the limitations of passer rating?
A: It doesn't account for sacks, fumbles, rushing stats, or game context (like garbage time stats).

Q5: Are there better metrics than passer rating?
A: Advanced metrics like QBR (Total Quarterback Rating) attempt to provide more comprehensive evaluations.
