Quarterback Rating Calculator

American football is one of the most popular sports in the world, and the performance of a quarterback (QB) is one of the most important factors in a team’s success. To measure a quarterback’s performance accurately, analysts use a statistical metric known as the Quarterback Rating (Passer Rating).

However, calculating QB rating manually can be complex because it involves multiple formulas such as completion percentage, yards per attempt, touchdown rate, and interception rate.

That is why the Quarterback Rating Calculator is designed—to help players, coaches, analysts, and fans instantly calculate QB performance metrics in seconds. This tool simplifies complex football statistics into easy-to-understand results.

With just a few inputs—pass attempts, completions, yards, touchdowns, and interceptions—you can get a complete breakdown of quarterback performance including:

  • Completion Percentage
  • Yards per Attempt
  • Touchdown Percentage
  • Interception Percentage
  • Overall Passer Rating

What Is a Quarterback Rating?

A Quarterback Rating (Passer Rating) is a statistical measure used to evaluate the performance of a quarterback in football. It combines multiple passing statistics into one single number.

A higher rating means better performance, while a lower rating indicates poor passing efficiency.

The NFL passer rating scale typically ranges from:

  • 0 (very poor performance)
  • 158.3 (perfect rating)

This makes it easier to compare quarterbacks fairly across games and seasons.

Formula Used in Quarterback Rating Calculator

The passer rating is calculated using a combination of four key components.


1. Completion Rate Component

(CompletionsAttempts)0.3\left(\frac{Completions}{Attempts}\right) – 0.3(AttemptsCompletions​)−0.3

This measures passing accuracy.


2. Yards per Attempt Component

(YardsAttempts)3\left(\frac{Yards}{Attempts}\right) – 3(AttemptsYards​)−3

This shows how productive each pass attempt is.


3. Touchdown Rate Component

TouchdownsAttempts×100\frac{Touchdowns}{Attempts} \times 100AttemptsTouchdowns​×100

This measures scoring efficiency.


4. Interception Impact

2.375(InterceptionsAttempts×25)2.375 – \left(\frac{Interceptions}{Attempts} \times 25\right)2.375−(AttemptsInterceptions​×25)

This reduces rating based on turnovers.


Final Passer Rating Formula

(a+b+c+d)6×100\frac{(a + b + c + d)}{6} \times 1006(a+b+c+d)​×100

The result is then capped between:

  • Minimum: 0
  • Maximum: 158.3
