How To Calculate Quarterback Rating

Quarterback Rating Formula:

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

Completions (comp):

Attempts (att):

Yards (yds):

Touchdowns (TD):

Interceptions (INT):

1. What is Quarterback Rating?

The Quarterback Rating (also known as Passer Rating) is a measure of the performance of quarterbacks in American football. It combines passing statistics into a single number to evaluate a quarterback's efficiency.

2. How Does the Calculator Work?

The calculator uses the NFL Quarterback 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:

\( comp \) — Number of pass completions
\( att \) — Number of 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.

3. Importance of Quarterback Rating

Details: The quarterback rating is a key metric for evaluating quarterback performance, comparing players, and assessing game strategy effectiveness.

4. Using the Calculator

Tips: Enter all passing statistics from a game or season. The number of attempts must be greater than zero for calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a good quarterback rating?
A: Ratings above 90 are considered excellent, 80-90 is good, 70-80 is average, and below 70 is poor. The maximum possible rating is 158.3.

Q2: Why is the rating capped at 158.3?
A: The formula was designed so that perfect performance in all categories would result in this maximum value.

Q3: Does the rating account for rushing stats?
A: No, this is purely a passing rating. Other metrics like Total QBR include rushing contributions.

Q4: How does this compare to college football ratings?
A: College football uses a different formula that produces higher numbers on average.

Q5: What are the limitations of this rating?
A: It doesn't account for game situations, opponent strength, or factors like sacks and fumbles.
