1. What is QB Passer Rating?

The QB Passer Rating is a football statistic that evaluates a quarterback's passing performance. It's used in both the NFL and NCAA, with a maximum possible rating of 158.3 in the NFL and 1261.6 in NCAA (though typically scaled to look similar to NFL).

2. How Does the Calculator Work?

The calculator uses the standard passer rating formula:

Where:

• A = (Completions/Attempts - 0.3) * 5 (capped at 2.375)
• B = (Yards/Attempts - 3) * 0.25 (capped at 2.375)
• C = (Touchdowns/Attempts) * 20 (capped at 2.375)
• D = 2.375 - (Interceptions/Attempts * 25) (capped at 2.375)

Explanation: The formula combines four components measuring completion percentage, yards per attempt, touchdowns per attempt, and interceptions per attempt.

3. Importance of Passer Rating

Details: Passer rating is a key metric for evaluating quarterback performance, comparing QBs across different games and seasons, and assessing overall passing efficiency.

4. Using the Calculator

Tips: Enter all passing statistics from a game or season. Attempts must be greater than 0. All other values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What is a good passer rating?
A: In the NFL: 90+ is good, 100+ is excellent. The maximum is 158.3. College ratings are typically higher due to different defensive rules.

Q2: Why are the components capped at 2.375?
A: The caps prevent any single component from dominating the rating and maintain balance between the four factors.

Q3: How does this differ from QBR?
A: QBR (Total Quarterback Rating) is a newer ESPN metric that accounts for game context, while passer rating is purely based on passing stats.

Q4: What are the limitations of passer rating?
A: It doesn't account for rushing, sacks, fumbles, or game situation. It can be inflated by short, high-percentage passes.

Q5: Who holds the record for highest career passer rating?
A: As of 2023, Aaron Rodgers holds the NFL career record with a 103.6 rating (minimum 1,500 attempts).
