1. What is NFL Passer Rating?

The NFL passer rating (also known as quarterback rating) is a measure of the performance of passers (primarily quarterbacks) in American football. It was adopted by the NFL in 1973 and ranges from 0 to 158.3.

2. How Does the Calculator Work?

The calculator uses the NFL passer rating formula:

\[ Rating = \frac{\left(\frac{Comp\% - 30}{20} + \frac{YPA - 3}{4} + \frac{TD\%}{5} + 2.375 - \frac{INT\%}{25}\right) \times 100}{6} \]

Where:

\( Comp\% \) — Completion percentage
\( YPA \) — Yards per attempt
\( TD\% \) — Touchdown percentage (TDs per attempt × 100)
\( INT\% \) — Interception percentage (INTs per attempt × 100)

Explanation: Each component is capped between 0 and 2.375 before being combined. The rating rewards efficiency in completions, yards, and touchdowns while penalizing interceptions.

3. Importance of Passer Rating

Details: Passer rating is the official metric used by the NFL to evaluate quarterback performance. It provides a standardized way to compare quarterbacks across different eras and systems.

4. Using the Calculator

Tips: Enter all percentages as whole numbers (e.g., 65.5% as 65.5). Yards per attempt should be entered as a decimal (e.g., 7.8 yards/attempt).

5. Frequently Asked Questions (FAQ)

Q1: What is a good passer rating?
A: 90+ is very good, 100+ is excellent. The maximum possible rating is 158.3.

Q2: How is this different from college football passer rating?
A: College football uses a simpler formula that doesn't cap components and produces higher numbers (typically 100-200 range).

Q3: What are the limitations of passer rating?
A: It doesn't account for sacks, fumbles, rushing yards, or game situations. Some prefer metrics like QBR that include these factors.

Q4: Who has the highest career passer rating?
A: As of 2023, Aaron Rodgers holds the highest career passer rating among qualified quarterbacks.

Q5: How is TD% and INT% calculated?
A: TD% = (Passing TDs ÷ Passing Attempts) × 100
INT% = (Interceptions ÷ Passing Attempts) × 100
