QB Rating Calculator (Passer Rating)













 

 

Introduction

The QB Rating Calculator, also known as the Passer Rating Calculator, is a valuable tool for evaluating the performance of American football quarterbacks. This metric provides a comprehensive assessment of a quarterback’s passing abilities, taking into account various factors such as completion percentage, yards per attempt, touchdown passes, and interceptions. Understanding a quarterback’s passer rating can help coaches, analysts, and fans gauge their effectiveness on the field.

Formula:

The QB Rating (Passer Rating) is calculated using the following formula:

Rating = (a + b + c + d) / 6 * 100

Where:
  • a represents the completion percentage factor.
  • b represents the yards per attempt factor.
  • c represents the touchdown percentage factor.
  • d represents the interception percentage factor.

Each of these factors is calculated as follows:

a (Completion Percentage Factor):

  • If a quarterback’s completion percentage is between 0 and 30.0, a = (completions / attempts – 0.3) * 5.
  • If it’s between 30.1 and 70.0, a = (completions / attempts – 0.3) * 0.25.
  • If it’s above 70.0, a = 2.375.

b (Yards per Attempt Factor):

  • If yards per attempt is below 3.0, b = 0.
  • If it’s between 3.0 and 12.5, b = (yards / attempts – 3) * 0.25.
  • If it’s above 12.5, b = 2.375.

c (Touchdown Percentage Factor):

  • If the touchdown percentage is below 0.0, c = 0.
  • If it’s between 0.0 and 11.875, c = (touchdowns / attempts) * 20.
  • If it’s above 11.875, c = 2.375.

d (Interception Percentage Factor):

  • If the interception percentage is above 9.5, d = 0.
  • If it’s between 9.5 and 1.875, d = (2.375 – (interceptions / attempts) * 25).
  • If it’s below 1.875, d = 2.375.

The calculated rating is then multiplied by 100 to provide a whole number rating.

How to Use?

Using the QB Rating Calculator is straightforward. You’ll need the following statistics for the quarterback you want to evaluate:

  • Completions
  • Attempts
  • Passing Yards
  • Touchdown Passes
  • Interceptions

Once you have these numbers, plug them into the formula to calculate the QB Rating.

Example:

Let’s say a quarterback has the following statistics for a game:

  • Completions: 22
  • Attempts: 30
  • Passing Yards: 275
  • Touchdown Passes: 3
  • Interceptions: 1

Using the formula, we can calculate the QB Rating as follows:

So, the QB Rating for this game is approximately 68.95.
